Topic: Coinballer - An open-source multi-player Bitcoin gambling game. (Read 1223 times)

I was trying to make some tests on the game but sadly, OP has closed it due to the lack of gamblers

Hopefully, there will be another game developed by you so that we can have a play and review. I guess it is because of the lack of marketing campaigns so that there are not many people know about the game.

Good luck OP

I opened the Coinballer last day through the Bitcointalk forum. However, I was aware of the site several days ago. I wanted to give the review but I could not manage the time to review the site. I have spare a little time and trying to give my review about Coinballer. Once I opened the site I tried to check the menu and sidebar.

I have seen:
1. Logo
2. Current Games
3. Past games
4. Rules
5. New games and
6. About
While I click on the logo it redirects me to https://decision.casino/ which listed two sites. One is https://coinballer.net/ and another is https://satoshiauction.net/ I think this logo should stand for the site itself. Whether it redirects to the self-site or nothing. It can't be a good sign that while clicking on the logo it redirects to another site. Also, the logo is not enough good. And another point is that the site has no favicon. It is not a big deal but it could be good if you add a favicon.

I have not found any issues with the current game section. It is enough good.

The past games section is also enough good. It is just awesome.


I could not understand why 100 players are worth the game. And it is not mentioned what is the length and how to configure the length. On the site, they mentioned the length is configurable but not mentioned the method. What is the meaning of nth while n=configurable?
Why anyone needs the BTC address of all the players? And how to collect all those wallet addresses?
For a refund of the bitcoin, you will charge 0.0001BTC. Why the fees are fixed while the bitcoin fees vary from time to time? If the transaction fees deduct more than these then how the site will bear the fees?


It is very good that the player can select the block. There is a box and after the box, there is "th" I could not understand why they used it.

A few more options should be added. And those should be terms and conditions, frequently asked questions, and a privacy policy. And also there should have a home page/about us page while entering the site.

Even from reading the OP, the game is easy to understand, Like the name goes "Coinballer", we all know who a baller is in terms of wealth, so the game is all about who is more wealthier, the richer you are, the higher your chance of winning in this game.

From what I understand, there is a coin pot where every player can contribute any amount of BTC they are willing to risk to, and this contribution will go on and on,  and if eventually players stop contributing to the pot, the pot will still be open until 144 bitcoin block pass, ones 144 Bitcoin blocks have passed without any new contribution to the pot, the game will automatically end, and the winner will be the player that contributed the most BTC to the pot, all the BTC contributed to the pot will go to him minus 2% percent of it that goes to coinballer.

I think this game is very easy to understand, i hope this explanation helps you grab with ease, what the game is all about and its mechanics.

So you are telling me to stop calling you Bot? 😉
What next? You are not an AI yet. 😂
No, you don't send it back. According to the game rules you deserve the amount I sent. It was the website error which somehow skipped the code block or missed the code block to execute your payout. Enjoy it brother.

This will be more on testing, user experience than a review.

First impression: the site is so simple yet confusing. People will get puzzled, what is Coinballer? Because the first page or home page doesn't look like the site is a game or gambling. I need to access the About page first but no help for what is the game is all about.

Rules Page
The rules is something lacking and still confusing, a step by step of How-to start a game or how the game works with images or videos will be good addition.

New game page
Errors should be emphasized like having a red font color or background color is better.

About page
About page should explain and define what is Coinballer, what is the game is all about, the advantage of playing on the site, the difference of coinballer to other gambling site, etc.

Again, i will ask to add these pages as i still cannot see it on the site, such as Terms, Privacy policy, Faqs, Contact ^(optional), as these pages are important and some question and doubts should be catered.

Gameplay
Asking someone's wallet ddress before creating a game is a backward move for me, this will take time and realization of why should i play with user xxx if he can beat my ass since i only have this xxx bitcoin. Lol.
But this also prove how relentless someone is when the game started ^{(when participants deposits)}

The waiting of x confirmations always be setback when sending bitcoin, currently, waiting 5 block confirmation from 6 is still a long time to wait. Many gambling sites offers a 1 confirmation time deposit already. Implementation of lightning will be a good addition too, like giving option for lightning wallet to users other than the native wallet address.

I don't like the idea of sending the same amount of pot to the >1 winners, when the fact that you deposit the most ^{(well, i deposit the most in game 21  )}. There should be a ratio of amount for the highest bidder, to the lowest if there are >1 winners.

Conclusion
The idea of the game is unique, this prove how blockchain can be used such game/gambling like the lottery of guessing the end digit of a block.
But the game is not really fun for me, its indeed time consuming when more gamblers like the instant results except for sportsbetting. Well, considering this is based on bitcoin blocks, so users should understand about this game first before proceeding.

Lastly, for those users of "first impression last" updating the UI to modern look should be prioritize.

I'm human
I was wondering why I received 0.00049 BTC, since Coinballer already sent me 0.0005 BTC when OP did the payouts manually. Judging by the blockchain, he sent you back your 0.001 BTC. This manual fixing is confusing, so now what? Shall I send it back to you again?

I confirm that I received the coins I sent. I did not check my wallet yesterday but discovered it today earlier. It took me sometimes to figure out from where the BTC came until I read it.

 
@Bot, because of the bug although now it's showing correct share on the site but you received only the half of the coins you sent. Which means you deserved more 0.00049 BTC from the game which I sent few minutes ago.
dfef6ca653710fa8f0e5a4ff5d8ac79cf215fcec2b50db16e652dfd09e55a4e0

I did not take the fees and things in considering since it's something better ignoring than taking the hassle of calculation.

How about you read the OP and correct it yourself?

This game is as transparent as it gets!

 -  In all the auctions or bidding or bet that I have seen and read, this is the only auction or bet that I have seen that increases the price without any item being contested. I'm just being realistic, if I look at it, it looks like a scam but it's not. Because who has the highest bids all the amounts that gave bids, right?

Apart from that, the only ones I have seen that will benefit from this a lot are the whales or rich people who have the ability to control the auction or bidding price. It's a win-win for the host here because he has a 20% commission if I'm not wrong, please correct me if I'm wrong. It's clear that there is manipulation here, I just don't know if I'm the only one who thinks like this.

Hi there! I was interested in potentially participating in the review campaign, but I wanted to check if there are still openings available.

I took a quick look at the gaming site, but I have to admit that I'm still not completely familiar with this type of game – it seems like a new concept to me. The instructions on the site are somewhat limited, so I'm planning to spend some time studying all the details and reading through the comments of other members in this thread before I make a decision about testing out the game. Is it still possible to join the review campaign at this point, or are all the spots already filled?

Much appreciated!
Sent you a pm for refund.

unfortunately i can't find the time atm to check Coinballer.net thoroughly and leave a decent review. therefore i would like to send the 0.0025 back to the sender and apologize again for depriving someone else of the opportunity to participate in this review campaign...
shame on me

The game obviously is going to interest people to know what a block height is. Which means it's easier to introduce bitcoin to new people, not just introduce but to tell them here is a raffle, you can join and the pot is currently xxx amount, if you join with yyy then you are going to win a prize which is guaranteed. Who does not like free money (when win of course). We all do. The person then visits the site, learn about block height. He is one step ahead now. He is also learning the use of bitcoin knowing that it's an alternative currency which has a good use (not just to use it in the raffle).

In summary, there are a lot to learn about bitcoin than to play the actual game. But the current site is missing such information. The site needs a knowledge base section. Where it can have few articles about bitcoin, it's history, how blockchain works. It can cover all technical and economical aspects of bitcoin too. This way the site can be another bitcoin ambassador to spread the words out.

It's more effective because imagine in a corporate event where there are few hundreds or thousands of people are joining the event from around the world or even say from a local area. We see in such events they host raffles. They can introduce coinballer raffle or coinballer can sponsor a raffle. Result will be outstanding. More people will practically learn about bitcoin and it's use.

There are another important information pages are missing. Term and condition page, privacy, gambling aware information. Most of the people do not read it at all but eventually these terms protect the business. I understand right now the main focus is to develop the game but once the game is fully working then the next thing to focus will be to improve the information around the site before the commercial launch.

Thanks Coinballer and everyone else who were involved in this testing especially Edwardard and the Bot.

I checked the transaction and couldn't work out why it wasn't processed. My best guess is that we received this transaction whilst I was manually upgrading the system and it somehow skipped over the transaction.

I've manually processed this transaction and made manual payouts accordingly. Sorry for the mistake.

I made a script to audit the other transactions and everything seems like it's working. Please anybody let me know if there are any other problems with transactions not being received.


Sorry for the bug, I have made the payouts manually. Please let me know if something like this happens again.


That's correct, the game is only extended if the bet is equal to or exceeds the maximum bet. If you think the game is taking too long, you can always make a bigger bet, to make it harder to extend the game.


Yes this is correct.


This should be fixed for all currently open games, I made payout manually again for games that finished.

If you are still seeing this bug, could you please let me know which game is effected?


I've added short video, FAQ, ToS, PP, short explanation about open-source, contact info, display unconfirmed tx, and time approximations to the feature list for us to work on. Thank you so much for your review.


The game between LoyceV and BitcoinGirl.Club was manually adjusted. I couldn't find the bug that caused this so if it happens again please let me know.

I've added automatic refund of transactions past the deadline to the feature list to work on.

Thanks for your review.


I've added displaying unconfirmed transactions, usernames, countdown for remaining blocks, returning deposits made after games finished to the list of features to work on.

You're right about the play not being very attractive at the very beginning, I will think about ways to improve this.

Thank you for your review.

The owners of both the games are the same, but both  (coinballer and satoshiauction) are very different from each other. You'll know if you actually try them out. Also, both are open sourced.

Jayce has been working with them as a graphic designer for the site(s). Its still in an early stage. Hang on!

  - They are almost the same as the satoshi auction, who is the original of the two? So why is the interface design of this platform like that? He's so plain and simple that it's a bit unattractive, to be honest.

Then there seems to be a lack of information on what its mechanics are, then from what I can see there is still a lot to improve on this website as well.

Coinballer.net Review

I have looked at Coinballer's service repeatedly over the last few days and can give the following review:

---

Domain:

First of all, I have to say that I find the domain very appealing. Although it is only a .net domain, the name Coinballer.net is easily recognisable and stays in your head once you have been on the site. Good job. IMHO, it is a key point if you want to attract new players/customers in the future.

Afterwards I checked the site (as I do with every new service I visit) once on virustotal and again everything looked fine. Very nice. Testing could start straight away.

---

First Impression and Game Rules:

The first impression of the website is simple and clear. That is good. You can find your way around the clearly laid out main menu. The concept looks new and unique (very cool!). However, you are soon faced with the question: What is Coinballer exactly and how does the game work?

And this is where the problems start, unfortunately. If you click on the menu item "Rules" (https://coinballer.net/rules), the rules are worded so briefly that an "every day user" is completely unable to follow. I showed the website to a friend of mine who knows very little about crypto. And he doesn't understand a thing.

And if a user does not immediately understand how things work, he will only very rarely take the time to do so (Remember: Most of us are no tech geeks, we need explanations!). As a result, he usually leaves the website and Coinballer loses a potential player.

IMHO, that's why the "Rules"-section urgently needs to be reworked! Preferably with a detailed (!) description that includes either screenshots or videos of a complete game sequence.

Furthermore, pages such as a FAQ, Privacy Policy, Disclaimer or ToS are missing completely. In addition to that there is no support or contact form in case of problems during play. Okay... there is a short about page with a link to a LinkedIn profile and a note that the website is open-source, but IMHO this part also needs some rework. Don't forget to add an email or this Bitcointalk thread. If you want to do some support here (plenty of other projects do that too!).

Play on Coinballer:



I wanted to start a quick game (Game 30) that ends in 10 blocks, but then realised that at least 12 blocks are needed. Unfortunately, nothing was written about this in the rules. But there is an error, if you try to go below 12 blocks.

Error: An invalid length was provided. Length must be between 12 and 525600 blocks.

Furthermore, the maximum value of 525600 is quite high. Inexperienced users could accidentally start a game that will take months to finish. However, the high maximum also gives the possibility to start games that run over a longer period of time. As a provider, you have to weigh this up carefully. If a long game period should also be possible in the future, I would include a disclaimer that tells the player:

"Be careful, you are about to start a game that may not end for several months/years!"

In addition, I would also add the note that transactions require 6 confirmations on the Rules/FAQ pages. Moreover, it would be helpful if transactions that do not yet have 6 confirmations are also displayed somewhere on the Game page (e.g. TX bc1... - Betting Amount 0.001 BTC - 3/6).

Another cool feature would be a big button/text letting the players know how much is in the pot and how much the winner would receive (prize money minus fees). This of course needs to be updated once a new bet is placed.

In addition, it would certainly make sense to move all played games to a separate page (perhaps "Played Games" or similar). Of course, later on you could also add pages like "Highest Games/Jackpot", "Most Players", "Most Bets". If players see that a lot of BTC is being wagered on your site and that there are a lot of other players, this should act as a great incentive for many to try your service.

Conclusion:

My experience with Coinballer is mixed. The product doesn't seem mature yet and it might need some work to turn this website into a real game that people actually play. Nevertheless, I find the idea exciting and with dedicated devs, a great product can certainly be developed here.

I also think the basic game idea is plausible. If players are willing to keep increasing their stakes, the pot can grow pretty quickly. And then players are likely to bet more and more to win the game (We all know this from auctions, where the bidders go into a frenzy and keep bidding each other up - even if they were initially only prepared to put down a much lower amount.).

The UI/UX needs to be reworked, of course. I don't want to list all the points I mentioned here again - but I think my review and the other reviews here will show that there is no shortage of points in need of improvement.

Anyway, I hope my review helps and you guys will create a cool game in the long run. Good luck!  

First: it felt more like testing than reviewing. I know the site is still in development, but in my opinion there are still too many problems to go live. The Rules don't cover some of the possible scenarios I can think of. My first impression after being happy to see a new type of game was confusion. It took me a while to realize for instance sniping isn't possible.

I started my Review yesterday:

I can complete my Review now that (my) Game 22 ended. See:
It took me a while to realize a game with 2 people and 2 winners makes no sense: you'll get back 49% of anything you deposit, and so does the other player. That means there's no incentive to deposit anything, but it did it as a test.
There was a problem with the game: one of the deposits wasn't registered, despite having many confirmations before the game ended. The final prize was based on only the first deposit, the second deposit is still unaccounted for. Needless to say: this shouldn't happen. Update: it's fixed.

Suggestions

• I get that you don't want to work with unconfirmed transactions, but can you at least add a notification when one of the addresses has an incoming deposit?
• Add a warning when someone creates a game with the same number of winners as players. Such a game makes no sense.
• The maximun number of blocks 525600 between the last bet and the deadline is very large. Not everyone knows blocks take 10 minutes, and if someone accidentally sets it to 10 years, they'll complain. I'd say lower the maximum number of blocks. See Game 27:
  
  

• With multiple winners, can you (optionally) make their prizes pro-rated? So if there are 5 players and 2 winners, each winner gets a prize depending on how much they deposited.
• Ask for less confirmations, waiting an hour on average for 6 confirmations makes the game very slow. And most websites don't require that many confirmations, usually 1 is enough unless there are large amounts involved.
• Add (optional) labels to the addresses when creating a New Game, to make it easier to distinguish addresses for the players. Or at least number the rows with addresses.
• The "Current confirmed block height" is 6 less than the current block height. I get that the difference is 6 confirmations, but this can be confusing. Example: if the deadline is 800000, and the current confirmed block height is 799995, it's already too late to make a deposit but that isn't clear from the game.
• I know it shows the current block height and the deadline, but comparing large numbers isn't trival. Can you show a countdown for the remaining blocks?
• I get that you don't want to work with unconfirmed transactions, but can you at least add a notification when one of the addresses has an incoming deposit?
• Maybe you can you add a FAQ with some screenshots of finished games, to make things clearer. And add more information, what happens for instance if a deposit confirms after the game ended? Will you return it?

Game play
I haven't seen a game that's attractive to deposit if nobody else deposited yet, and that could stop people from starting a game.
Takes for example Game 21:
This game has a minimum of 3 winners out of (up to) 10 players. If you're the first to deposit, and nobody else deposits, you get back less than 33% of your deposit. That's a huge risk to take!
If 5 others have deposited (that's the current state of the game in the screenshot), you'll need to deposit at least 0.00010000 BTC to get a prize (or 1 sat more to eliminate another player). That a much more attractive bet.
If there's only 1 winner, it's still not attractive to be the first, but at least you'll get back 98% if nobody else deposits.
I can't think of a way to improve this, and it may be inherent to this kind of game, but shouldn't a game be attractive from the start?

I wanted to be fair, so I sent 0.6mBTC (half of the bug bounty) to your wallet. We both played a role in finding the bug, so I thought it was appropriate to split the reward.


It appears that the issue has been fixed for everyone. Based on the outcome of Game #22, it seems that LoyceV and BitcoinGirl.Club shared the pot. However, upon further inspection, it looks like the second deposit was not taken into account in the total balance. This could potentially be another bug, or at the very least, a flaw in the software that needs to be addressed.

@jackmurray, perhaps the simplest solution to this problem would be to automatically return all transactions that are confirmed after the deadline to the sender (minus the transfer fee)?

My review about Coinballer (Done)

First visit

Using Tor Browser, i visit Coinballer website. I don't see annoying "security check" or CAPTCHA which is a bit nice compared to few casino i've visited. The website design is extremely simple which reminds me of 90's website, although slightly modern design would be great and could attract more people. I have slight positive first impression.

Just like other member, i have difficulty understanding the rule. I had to re-read the rules few times and read discussion among member in order to understand the rule. Even so, there's one point i misunderstood (more detail below). So it'd be great if short video or example of game session with some explanation is exist.

Exploring other page, i didn't find few important page such as FAQ, ToS (Terms of Service) and PP (Privacy Policy). Many people would either perceive it as red flag or doesn't take your casino seriously. You really should add those page since it also could save you from answering similar question many times.

As open source user, it's nice addition that the website is open source. But most people either don't care or don't know the benefit of open source software, so adding one/two paragraph explanation about it could give user better impression. And while we're at it, the "About" page should include another ways to contact you (such as email address or this Bitcointalk thread).

Play a game

Since the game require you to include Bitcoin address of all players in advance, i decide to include Bitcoin address of all reviewer and see who joined. It's more convenient and took less time compared with contacting each potential player where. As you can see on game 21, i set it to have 10 player, 3 winner and 576 blocks (about 4 days) length. Initially i mistook 576 blocks as length of whole game rather than length between last bet and deadline. Had i known about it, i would set it to only 288 or 432 blocks (about 2 or 3 days).

Checking other games, there are many finished game and unfinished game with empty pot. It'd be great if list of finished game only can be seen on different page. And since there are many unfinished game with empty pot, personally i'd like the website to emphasize game with non-empty pot.

Now about UI/UX, there are few lacking things. While now we know 6 confirmation is needed, it'd be great if the game show transaction/balance which doesn't have 6 confirmation yet. It'd be nice assurance for user that the system already detect the transaction and they send Bitcoin to correct address. The website also only use block height/total block count as time reference. Adding different time unit such as "576 blocks (4 days or ended on 10/01/2023 10:00 AM)" would give user better idea and saving their time from using calculator and looking at calendar.

Game 21 finally finished after 4.5 to 5 days since the creation. I sent 10K satoshi during the game and received ~11K satoshi in return which is nice. I briefly checked the transaction on certain Bitcoin block explorer and found out each transaction only send Bitcoin to one winner. I would recommend you to perform batching in the future to reduce satoshi spend on TX fee.

Conclusion

I have not so positive experience with Coinballer. The game itself isn't really fun since i have to contact people in advance, which is cumbersome when people around you isn't willing to bet with real money. I also feel the only suspense/adrenaline comes from player who're willing to keep make a raise. But take note i'm not gambler.

From UI/UX and marketing perspective, some effort is needed to attract average player/gambler. Aside from what i've mentioned above or already mentioned by other player, here are few additional recommendation.

• Coinballer source code has no license yet, so you should add one. MIT is simple and popular option, but AGPLv3 also works if you want to put few restriction.
• For game with multiple winners, having option to share the pot evenly or based on deposit amount would be great option.
• Let player know that amount on "Currently each winner will receive" doesn't consider Bitcoin transaction fee.

If someone bids 1 mBTC, and someone else bids 1.01, they can play ping-pong by adding small amounts.

Agreed, you can bot it though just to annoy people.
If I understood the mechanics, only a higher than current max bet would restart it - and that's the way it should work IMO.

______________________


Good that this was fixed already, I just came to confirm that although I'm the only one that bet on the outcome eventually I walked away with 0 BTC

Is it fixed for all currently opened games, or will it be fixed only for the newly created ones?

As I understand the betting rules. The only allowed bet is the max bid made by the winning user. So if someone bid 1mbtc then no one can bid lesser than that amount to become a valid winning bid for the auction.

This is what I understand on the game design to avoid spam bids just to extend the duration. @jackmurray can you verify this?

The payment confirmed but the amount still does not reflect on the site. I am taking a note about it. May be a bug?

I think once the deadline block height confirmed it will activate and send the winners their coins. But question is what will happen when there are unconfirmed tx?
They are not taking it in calculation until 6 block mines. But if they take it in consideration before the tx confirms then there is a chance for double spending too.

In our case game 22. My tx confirmed already but it's not showing on the site. Considering it's not showing yet, the prize for both of us are 0.000049 BTC each where it was supposed to add more 0.001 BTC with the total except the 2% charge.

Update:
Yes, just read LOL

It looks like you made a deposit that didn't show up even after 52 confirmations.

Fees spiked yesterday. @jackmurray : can you check the above transaction? What happens to a deposit if it gets confirmed after the game ended?

There were a few people saying they want to join an open game, rather than have to create a game with players' addresses.

For these people wishing to join an open game, you may prefer https://satoshiauction.net instead, which is a similar game, but every game is open to everybody to play.

We got some really cool testers down the line. Keep it going guys
Yep, and btw if anyone wants, they can access the site through .onion link as well provided below.

Critical reviews are welcomed if they are to the point. Everyone feel free to point out any major issues you got. I agree with you that a short youtube video explaining the game will be much appreciated (as visual info is grasped better than the text).

---

Good find @FatFork and congrats for the bonus tip , well deserved !

Yes, you found a critical bug. I've fixed it here.

I've sent 0.00121738 BTC to the address on your bitcointalk profile as a reward for pointing this out. Thank you.

In theory, that's the way the game is supposed to work (or at least, that's our understanding of it). However, it doesn't seem to be living up to that expectation in practice. We'll have to see how Loyce's game turns out before we can say for sure. In the meantime, you can check out my review of Game #23 in the previous posts.

No, because OP has confirmed that you can decide how many winners will be there in a specific game whenever you create a game. I was also confused about this but I have even seen 2 players in 1 game and both of them getting something because the creator chose 2 winners (LoyceV's game you can check in this thread).

So does it mean that people wil contribute to the pot and in the end only ONE person will win the whole pot and the rest all contributors will lose the moeny  
Also, this mean that the game does not depend upon luck but the one who is able to contribute most money will win in the end. This favour the rich as if you have a lot of money you can win the pot. Anyone with limited money will lose the game    This game is for the rich people ?

It looks like many members have already identified several issues with the game. However, the most concerning issue for me is that I believe I have discovered a critical bug in the gambling mechanics. I'm curious to know if anyone else will experience this problem as well.

In the following part of the review, I will be discussing Game 23, which was a completed game between me and cryptofrka.



Game flow:
cryptofrka funded 8000 sats to this address: bc1qgdh69sd0ldyapk3ux8kztkhfpx25le7lt6fjt0. I was supposed to send a certain amount to the address: bc1qdm8mnf5mfnhw6447dkev6s3fze63333vch5h28, but unfortunately, the transaction wasn't confirmed before the deadline due to a low fee. However, after the game round ended, I received an amount of 7840 sats to my payout address in this transaction.

If my understanding is correct, the system awarded the entire pot amount (minus the 2% fee) to only one participant (me), despite the game being set up for two winners (which is evident from the screenshot). Furthermore, I won the game even though I didn't even participate in it. I'm unsure if this was a random occurrence or due to my address being first on the list, but either way, this is not the intended behavior of the system and I believe it to be a serious bug.


*OP, this is my review, although I'm sure I will contribute to this thread more in the future and express my opinion as the game develops further.

If it works this way the game is open to cheating where a player gathers a group of people to watch the game and keep raising bets by depositing dust to the same address. I bet it would be possible to make a bot to do it automatically. Once the number goes up without the bot depositing anything, the bot adds to the pool from your wallet to make sure you're always on top, even when you sleep
The same bot could also extend the game forever by adding one sat per hour or something. Of course nobody will bother to do that when people are fighting over pennies in a local game, but the possibility is there.

I understood that differently, for example if the max bet is 1mBTC, a bet of an additional 1mBTC or more needs to be made to restart the timer.

But yeah - haven't tested it so I'm not really sure. Your logic makes sense as well.

Anyone can deposit to the highest funded address, thereby raising the maximum bet.

Based on the rules, not really.

The rules say:
The game ends when a certain number of bitcoin blocks have passed without a raise that is equal to or exceeds the maximum bet. This length is configurable.

Haven't tested if that is actually true ingame though.

But yea, if you start with pennies bets, someone can raise contnuously just to annoy you

Each deposit resets the game:
So any troll can delay our bet for a few cents per day

Let's have some fun then LOL

But I am going to use the address given for me. So that you don't tell people I did not send anything 😉

Edit:
Which means we need to wait long time what will happen if the deadline block resolves before my transaction confirms?

To be honest this game has too many weaknesses to abuse.

Correct. And that makes it kinda useless: if you do nothing, you win 0.00004900 BTC now. Anything you deposit, adds to your and my prizes. In retrospect, this wasn't my brightest moment

I just realized it doesn't even matter which Betting address from Game 22 you use. I could just as well have deposited to "your" Betting address, the result is the same.

Utterly pointless

How do I join? I even tried to join Bot's game number 22. There are no button, no input box, nothing LOL
Someone please explain.

Edit: Let's see if I get it correct.
I see game 22 has my address. So it's between me and Bot.
So it needs to send btc to bc1qyhcndnuufr92dtl6gvxdctf3ctcyu0nfq6kzp3

Assuming bc1q5gz6c5u3c8p6e6mtgnq0gxre9mkrgvav3n0q4g is Bot's address. According to the rules, we will share half of the money (of total).

Does it means I will get 0.00004900 BTC even without sending any BTC?

Shall I wait? 🤣
Don't worry I will send you if anything arrives in my address. Let's test what happens.

Or I will need to send any amount of BTC to share the prize? I will send a fraction of BTC which will be just enough to make a transaction 😉

IMO this is going to extremely limit the amount of players you'll get on the site. It's just too much of a hassle to gather a group of people willing to play this game with you and then make them join the same game and deposit coins.

Nobody is going to start empty games knowing that he'll be charged anyway, regardless of whether the game takes place. I know this is a beta stage of the game and it's how the system works, but the whole point of playing a PvP betting game is getting a random opponent.

I just know that if I try to explain to a friend that if he goes to that site he can win money if he wagers more than me, but loses if it's less than me, and then we all pay a fee on the win, I'm going to get that "are you trying to scam me?" look.

My Feedback

• The current confirmed block height display on the game is delayed by 7 blocks on blockchain record. This should be sync since players is checking on it real time when they place bets.

• I’m having problem too on creating multiple game using different wallet address. The new game that I create doesn’t appear and all the field is clear after I click the create game button.
• Make all the wallet address clickable with embedded link from blockchain explorer so that every bets can be verified easily by just doing one click on the address to redirect on explorer.
• Add game result summary on each round ended that includes the total winning profit of the winner excluding the transaction fee and also provide a transaction ID for the payout to the winners to give more transparency to the outcome.
• Please make a step by step guide on how to play the game. A demo video or picture instructions is easier to understand rather than a pure words of guide. This game is new and easy to make an error that will result to permanent loss once user sent Bitcoin to the wrong address. It’s better to have a clear mechanics on the game to make it clear. Most of the tester here is not new on gambling yet we are all still confused on the gameplay using the rules given on the website.

*I will keep updating my feedback as my bet progress.

That's to the point.
Now I understood when OP said that I need to speak with people who are ready to play the game, before I put different payout addresses.

@OP, I have an idea which might help you provide an exciting game to your players.
Why not ask everyone to create an anonymous account with an already allocated alias to them once they visit the website? They can decide if they want to add a password and an email to their account. If not, they will only need to save their private link that goes to their alias and their games as well as their stats.
I was reminded of a game named Satoshidice and I think that game used the same method.
This way, nobody will need to provide any payout address or need betting address, they will see everything in their profile (their betting address after the game is created, and payout address will be the same used to send the funds from). Example: I create a game, the game will only show my alias and the next person will be able to join the game (if you add a 'join' button there) and the host will still only be able to see the next player's alias without knowing who is behind it and betting how much, because only the 2nd player will see his personal betting address for that game he joined, so everything is hidden here except the alias). However, you may determine the number of winners on the game page and let the aliases know how many winners will be there for that specific game.
Hope this helps.

Review

I really dislike giving negative reviews when I know that somebody that cares about the product they are making is on the receiving end of it - and I feel that's the case here.
However, I hope you will understand that the intention of the review is to give you sincere input and some ideas on how to make the game better.

First of all - the rules have to be described better. Maybe use some examples, or make a 1-minute youtube video. Before creating the game, I did not know how it works at all - so if I just wanted to join somebody's game I would not know where to start.
I still don't know if it is possible to join somebody else's game if my wallet address is not defined when the game is created - and if that's the case, then it's something that should be added.
The distribution of the rewards in case of multiple winners should be explained as well - is it a percentage of the bet or just 1/3 of the amount wagered, and in that case 1st and 3rd place pay out the same. In that way it is even possible to win the competition, and end up with a loss.

If I'm playing a game, the experience should be way smoother. In the current state I'd have to collect people's addresses before creating a game which is kinda pointless - the game should allow me to join whichever open game is currently available.
Again - if that is currently possible that is great - but the site does not tell me that I can or how can I.

The biggest issue I'm having is that it should be a wagering game, where I bet against someone else for profit. I should not know how much he wagered - because then I can always react later and easily bot the system so it always shows me the ideal bet to place.
6 blocks confirmation is also something that should be lowered.

I feel this is in an early stage and many issues need to be changed/revised if the game has a chance to have a future.

I do like the simplicity of the webpage though - to finish it up with 1 positive.

The creator of the game decides how many winners the pot will be divided among. For example, for Game #25 it would be you.


If you create the game and no one else participates, then you will be the winner and win the entire pot (minus 2% fee).


I believe you've created a game for only one player since you haven't defined other payout addresses.


Yes, I think so.

That would be ideal, yes. But I'm not skilled a developer enough to add this feature yet, it would take a lot of work to process reorganisations if there is a small fork in the chain.


It is counted if the transaction makes it into a block before or equal to the deadline height. The the deadline is reset to 144 blocks later (or whatever you configured the game for).


It is configured at the start of the game, the person who sets up the game decides this.


The platform still takes 2%. I can configure this to take out only a withdrawal fee, I guess.

You should also arrange with the players in the game to play before the game starts.


The person who creates the game must provide the payout address for each player.

Then the betting address for each player will be displayed on the game page.


Yes, that is correct. The betting address is the same, and each new bet is added to the previous total bet.


Heh, yeah, 2-person game with 2 winners is kind of pointless.

So, who decides the number of winners in a game?
The host himself/herself?

And let's say I create a game and nobody participates, what will happen after the number of blocks passed?
Will I get a refund (excluding the 2% fee that the platform takes)? Or will it be a full refund? A little bit curious about this.

EDIT: Where does the 2nd player gets his betting address?

For example, I created Game 25, the betting address left from my address is for me, right?
Then where will the 2nd player send his coins? If he will send them on the same betting address as mine, then will the 3rd person use 2nd player's betting address to send his bet?

If someone wants to increase the size of his bets, will he use the same betting address where he sent his funds earlier?

That's a lot, usually 1 is enough for small amounts.
Follow-up question: what happens if a transaction is added right before the deadline? Does it wait for 6 confirmations and still count it?

My game with 2 players is an instant win for BitcoinGirl.Club now. A 2-person game with 2 winners was a bad idea.

I appreciate the effort you made to update the information on the website. However, I see that there are still some delays. For example, in Game 23 I have a transaction with 7 confirmations, but the site still doesn't reflect the correct balance.

EDIT:
OK, I see now that the balance is updated. I'm not sure if it's because of the 8 blocks after the first confirmation or some unspecified time after the 6th confirmation. Btw, do you really need 6 confirmations for this? Wouldn't it be better if the balance was reflected in real time?

If there are 3 people playing a game with 2 winners, and they bet 10k, 15k, and 12k satoshi, then the 15k and 12k betters will each win.

The total in the pot is 37k, so the total winnings will be 98% of that, which is 36260 sat.

So the 15k and 12k betters will each receive 18130 satoshi.


Yes, everything is transparent. This is intentional, otherwise it would not be possible to check the host is behaving correctly.


This is a great idea, thank you so much. I will add this to the game page now.

It means the number of winner. 1st, 2nd or 3rd base on the game summary when you check active games. I agree that the statement is kinda confusing. It really just the ranking of winners based on the amount of bets.

All the bets will be updated on the game summary after 6 confirmation. Everything is recorded on the game summary.

The only thing missing is the announcement of winner and how much he/she win excluding the fee besides manual computation on data given as per the game 1 result https://coinballer.net/game/1

Guys, I'm a bit confused on the whole concept.
The nth person who places n (highest amount) number of btc till it reaches current block+ 144, will be the person who takes part of the pot or the whole winnings?

And when everything is transparent on the Blockchain, won't the players know all the bets by checking each of the addresses on the list? Or am I missing something?

What I’m confused right now is there’s only one betting address during the start of the game which is assigned to the creator of the game base on my created new round Game 18. If I understand the game correctly, New player that want to challenge needs to send first Bitcoin on the first betting address before  the game will assign new betting address to the new player then repeat process for new player. This kinda confusing instead of having a button to add betting address for new participants by just entering there own wallet address like the procedure on creating the game to make it easier to compete.


I’m late to see your post because I already created a game before you made a post. Also I’m waiting for my deposit to appear on the website which makes me offline in the forum for a while.


This is true. I patiently wait for my deposit to appear and it took 6 confirmation before my bet become updated on https://coinballer.net/game/18

Thanks all for testing the site, I really appreciate it.

Yes, there must be 6 confirmations before txs will show up.

I've added a message on the site making this more clear.

The site is in active development so please let me know here if there are any more issues.

I briefly checked source code of Coinballer and found it uses Bitcoin full node to obtain the data[1]. And it looks like it has 6 minimum confirmation[2], so that might be why the address/pot balance isn't updated yet.

[1] https://github.com/jackmurray90/coinballer/blob/main/bitcoin.py#L6
[2] https://github.com/jackmurray90/coinballer/blob/main/bitcoin.py#L14

I think the balance won't show, otherwise if you were playing 1v1 you'd always know how much the other person has wagered.

Still - it can be tracked on the BTC explorer - so I can see how much each of you wagered anyway.
To prove this, LoyceV's wager is 0.00000666 BTC, whereas yours is 0.00001000 BTC. Please confirm if true.

At this point I have a lot of issues with how it is set up and considering that BTC is transparent - in this state the game is not in a good state.

I wonder if it has to do with the fact that I funded 2 Games in 1 transaction.

Well, it looks like we've both got three confirmations on our transactions, but the game balance is still stuck at zero. Is this a glitch in the matrix, or just a cleverly disguised feature? Hard to say... Only the developer knows for sure.  

It does not matter if i understand correctly, since the winner will be identified on what betting address has the most balance in the end on the set block.
So anyone can send btc on the betting address and winner will receive all the sent btc from all of the betting address ^{(or from anywhere else)} minus the host fee to the winners payout address.
This is all assuming since there's no rules mentioning that its not allowed.

If I understood correctly, to participate in Game 21 created by ETFbitcoin, you need to send BTC to the designated "Betting address" (listed in the left column of the table).

So for example, my "Payout address" is in the right column and my "Betting address" is in the left column:



It's a good question, but unfortunately the instructions are incomplete, so I'm not sure if the address the funds are sent from matters or not. It's possible that it doesn't matter, but without more information, it's hard to say for certain. The only way to know for sure might be to try it and see what happens.


I agree.

I think I'm starting to get it. See https://coinballer.net/game/21, find your Payout address in the list, and deposit to the Betting address that's left from it on the same line.

I don't think the sending address matters.

Does anybody have a clear understanding on how to participate? To which address should I be sending my bets?
And what if I want to send from another wallet? Am I excluded because only 1 of my wallets are registered or not?

At first glimpse it is quite confusing to understand how the game works.

I am inviting everyone who accepted on "Coinballer Review Campaign"[1] (@shasan @Coin_trader @PX-Z @LoyceV @bullrun2020bro @BitcoinGirl.Club @FatFork @cygan @cryptofrka) to join Game 21[2]. Here are the details of the game,

• Bitcoin payout address is based on campaign's spreadsheet[3].
• Top 3 player can win the game.
• The length of this game is 576 blocks (about 4 days), where deadline of the review is 7 days.

P.S. In next few hours i'll send 10K satoshi to my payout address.

I'm not much of a gambler, because I don't want another addiction in my life. But I like games, and Coinballer looks like an entirely new concept. The last time I saw a new game, was 4 years ago, but that one doesn't exist anymore.
The site works on Tor without complaining or captcha. I like the simplicity.

But my first impression: I don't get it
The Rules don't help much:
I created Game 20 Game 22. The 2 hours isn't enough if you're offline, let's make that Game 22. From what I understand, we'll indeed receive an equal share of the pot. But we don't need to contribute the same amount, and it looks like depositing 0 is enough for a share too.

Suggestion: The (potentially long) list of addressess makes it hard to find your own. It would be nice if New Game allows Labels to be added (although that creastes at the risk of tricking someone into depositing to the wrong address).

---

---

I've deposited to Games 21 and 22, but after 2 confirmations, still nothing shows up.

Would you like to play with me?
I assume you have already created a new game? Can you confirm that it is okay for me to send my deposit to the specified address?

EDIT:
I'm backing off. I've already found a new partner.

Do you want to make this as an actual gambling business or you are simply experimenting?
This forum thread seems kinda lazy for a serious gambling website.
Your concept isn't new and there were multiple games trying to copy the same concept.
I wonder how do you plan to stand out from the crowd and offering something, that's never seen before.
Your website looks clean and simply, but it lacks uniqueness.
Good luck with this project, but I'm not an optimist.

You have to create the game yourself by clicking on the New game button and the address for payment will be available, from this moment a round equal to 144 blocks begins. I just tried it and that's what happened, of course there will be a lot of empty rounds, but the initiators are always the players themselves.

It really took me more than five minutes to understand the system. A very fresh idea, at least for me. First I thought I can bet on existing games but then realized I will need to be on the list when the host will create the game (I am still not sure). Still in doubt which address to send the stake, how it will be held (assuming the site will give an address) and many more things. I will wait for response for a partner before I give my review.

First of all an algorithmic typo needs to be corrected:
On the New game page, nth highest bet needs to write a method to replace "th" with

"st" when n=1,11,22...
"nd" when n=2,12, 22....

Full review is in progress which means I will update this post later or I will quote only the review part and continue in a new post.

I'm not so sure that this kind of game mechanics is new, it's simple auction-style bidding in a digital format, and this type of gameplay is something we've seen before. And, you don't have to actually play it to understand it because it's actually very simple, whoever makes the highest bit wins the entire pot.


A strong reputation is a no-brainer for any gambling platform worth its salt. After all, players entrust their hard-earned coins to the custody of the platform, and a spotty reputation is a surefire way to chase them away. The design of the game requires this trust, making the reputation of the platform a vital factor in its sustainability.

Signature campaign doesn't increase any reputation since the purpose is only for advertise their site in this forum, you need to look 1xbit where they're launch many signature campaigns and they're still scam until now. This is why you get red tagged due to your own careless lol.

@OP why need to be hurry to built reputation?

It's because such site has limited bankroll or they're don't have any interesting promotion to attract new players.

Aside from the fact that this site is open source which is a new introduction to gambling which is a plus for the coinballer, its way of receiving deposits is may too centralized and at that, there is a high risk of the wallet holder walking away with players deposits, it is better to use casino smart contract address than having to deposit into a single wallet. I know there is the prospect for this casino to succeed and build a good community base in this forum by listening to feedback and taking the necessary steps to build a formidable site that will become 1st open source gambling site in the forum which is a good development to look out for, I have not attempted to visit the site but since the just launch their review campaigns. So let's see how things go as we read the reviews of members of this forum.

I don't know, but it seems like this type of game or bet is very new to this forum or ever to the casino. To understand it we have to play it or at least Op can give a free test so that we become more familiar with how betting works on this new gambling site, but seeing what Op has explained gives a little illustration that we have to prepare good budget to win the bet.

Thank you so much for testing the engine, we have responded to this problem and added address validation to the site.

I have sent 0.002 BTC to your address at 1BtcBoSSnqe8mFJCUEyCNmo3EcF8Yzhpnc as a reward for pointing this out. Thank you again.


Thank you, I have added a link to LinkedIn.

As for the UI, I am not a frontend designer. I will pay for help with frontend design if the site gets a little bit more attention. Thank you for your feedback.

Whether his project is successful or not, building his reputation on this forum should be a good thing to do if he plans to stay longer and want to get customers from here. If it fails, sure there might be some "bad" projects in his CV, but if he's honest then people have some history to look into.

BTW, OP mentioned he used to work for FAANG in the past. If this is true, I think putting a LinkedIn or something similar is a good idea. Your current about page tells so many things but it is hard to look into detail about it. Since you decide to open up about your identity, posting your work history in detail should not be a major problem for you right? That way users can have an easier way to check your CV without waiting for days for customer support to answer their query.

Consider improving your UI design too. Your website looks very simplistic and it is hard to sell to young people nowadays. If they are your target audience, UI is important. But of course, it should not be a priority if there is still a function/feature that you need to implement asap, such as a possible threat of invalid data mentioned above. While it is unlikely, you should not underestimate people's carelessness on the internet. CMIIW.

Better to hire a manager for this and an escrow so we can have the assurance that this promotion is paying and OP should also consider the budget for promotions. I’m hesitant to visit the site as well because of the way he introduce this project here in the forum, having a limit for a gamblers for now is quiet ok, just need to understand the mechanics to qualify.

Though he posted profile on the site, it doesn't mean he can easily earn credibility on this site.
It would take time before people will be comfortable sending money to this game.
Because at a glance of the site itself, it is not the interface of a regular casino, it is more on leaning a casino with short lifespan in the business.
We don't know how this will progress in the coming days, but sure, he has all the time to build his reputation for this project.
But based from my experience, I have seen such similar concept of game not to survive long or not attracting enough players to sustain this business.

If you have received a signature campaign by one of the sites, then you don't need to think about increasing your reputation in this forum.
Your job is only to carry out promotions as it should be for other members who use this forum to be able to attract or make other members interested in what you have promoted.
If you really want to improve your reputation, do it by serving and providing comfort to users who visit your site.

You can slowly build up your reputation by handling your players well. And by well, I mean, no delayed payout/withdrawals, and good customer support (through email or here in the forum). Running good promotional events like signature campaigns, and contests is just a plus.
As for now, focus on building your site since currently, the website itself looks bland and uninviting. It would have been nice if it had a little artistry or even just a few touches of colors before you launch a campaign to promote it. But since yo have Jayce working on it, I'm sure it'll turn out great.
Also, adjust a few mechanics in the games. Coinballer for example has a 144-block waiting time just to see the results. No casual player would wait that long.

Basically signature campaign has nothing to do with reputation, reputation is more about how the site serve the players.
OP should not be focused on how to get reputation but he should be focused on how to manage the site and serve the players so players will feel great to be there.
However I really doubt that this kind of game will survive in this gambling industry.
He has started a signature campaign but he forgot that it wont attract players to play, because campaign is just an advertising tool to make people aware about its existence but what make people attracted to play is something else.

Happy new year to you guys and have the best of 2023 to coinballer, welcome on board and am happy that you are responding to all enquiries and adhering to a few suggestions as there made here.
Between since you already working with Jayce to design for your site graphics you indeed made a good choice working with Jayce so we can expect something good after the set is ready.
wishing you guys the best in the new year and beyond.

Thank you for mentioning my service, SquirrelJulietGarden I want to confirm that jackmurray and I have been working on it since the last month and hopefully we could show it as soon as possible. Happy New Year guys!

From your signatures, you owned two casinos: Coinballer and Satoshi Auction and one exchange.

I saw two mini signature campaigns for Coinballer and Satoshi Auction that were started hours ago.
With the announcement for Fryx Finance, you should make a graphic for it.

For two casinos, you can hire jayce to design more attractive graphics.

Making multiple accounts won't give benefits the cheaters of whatever you call them for this game since only one who will win – the one with biggest bets of the day.

About the holding of funds, it depends on the reputation of OP and the site, its like doing escrow here, which needs of time to allocate to make a good reputation – its all about trust. Which i think is need risks knowing there are escrows or services who runs its users funds after building its reputation.
If something a smart contract can do about the holding and dispersing the funds to the winner, it will be a great feature.

There's no quick fix for building a strong reputation online. It takes time and patience. You need to be consistent with your efforts, and if you're willing to put in the work, it will pay off. I agree with the given suggestions, by actively posting updates and following best practices for interacting with others on the forum, you can steadily improve your reputation over time. It's all about consistently demonstrating your credibility, reliability, and professionalism. Keep at it and your reputation will surely grow!

Or some will make their multiple accounts to participate the game.
How can the OP make sure that there will be no cheating on this game?
Also, with what is happening these days, how can you trust the word of an anonymous person?
Assuring no rug pull will happen if he will be holding a significant amount of money.
Indeed, it would take time for a new site to build their credibility in this community.
If the person is serious on this business, he will slowly improve his site for the betterment of his game.
But with the content of his site right now, I don't think many people will trust a handsome amount of money on his site.

This will take a lot of time and if OP is serious about the services he’s offering right now here in the forum, then probably many will slowly trust this platform. It will always hard to attract 100 players in just one game where they will gamble to win the spot, probably many are still hesitant to try this platform. 2% fee for the host seems reasonable for me, will try to know more about this project first before trying it.

^Definitely right, there is no shortcut in gaining trust here, it should take a long process altogether with a good service with your gambling casino that should not have shady activities or becomes rug-pull top the users. Revealing your identity is not ideal for fast gaining trust, probably it will boil out to the worst if revealing your identity becomes a danger to your side. Running a signature campaign or any business ad, being active here in the forum will make your reputation increase. However, you are in a good step, in answering those concerns about your website on this thread will increase the chances.

Just checked the site and I found out that the site is very similar to this one which I can say created by the same person or a team. This is the site I was talking about. I posted in it earlier but it seems that OP deleted the thread of promoting the site when I checked my post and I can't find it in my post history. I was just curious as to why OP deleted the thread. It is a different website if I say about it but many people will say that these websites are created by the same person or team because of its similarity.

Unfortunately, you cant fasten this process, but being actively posting here your updates, doing trades to anyone, as well as following some recommendations to your site, fixing/solving issues, etc. can help. Well, also running a signature campaign which i saw that you already did will also build reputation of someone else business/service here.

Thank for you for testing the engine.

I believe that people can only put html escaped text into the page. I'm not too concerned about this vulnerability at the moment.


I promise not to rug-pull any of the players that I am hosting the site for.  

Yes, I agree that a smart contract would be better. If I get more funding I will fund development into this.


Thank you for your appreciation.


Thank you so much for the feedback, I have purchased the domain https://decision.casino and will work on adding the brand to the other websites soon.


Like I said, I promise not to rug-pull on any users. I've also been transparent about who I am on the website, so my reputation is on the line.

Please anybody let me know if there's anything else I can do to increase my reputation.


Thank you for the feedback, I will add the feature to have a top 5 players win soon. And thank you for the words of encouragement.

^ Hey Jack Murray, it would be nice if there is a top 5 winners, it is very hard to compete in only one position and it is unfair to the small-scale players like me that only spend an amount that we can afford. However, even though it is open source but I agree with the above said that it should be on a smart contract that player only connect their wallet via API, they still have control over their wallet. Overall, your concept is good for those gamblers who care about their privacy. If you will succeed here and become a fully well-established gambling casino, for sure you are the first gambling casino that has that kind of feature here. If you are serious about this you can make an ANN thread here.

From what I understand from OP's explanation of the game play or should I say mechanics, this is not a fair game, it a game for only the rich, any pleb who enters this kind of game would just end up wasting their money, or should I say would be foolish because he or she would just be giving the little he or has to the rich.

Its a game for the rich to debate or fight over who is richer, and as we know, when two elephants fight, any grass under their feet suffers, so Goodluck to those playing, I am not a rich man yet, so this type of game is not for people like me.

I believe this website is connected to your Satoshi Auction(https://bitcointalksearch.org/topic/m.61523202 ) since it has same format and both manage by you. Why not merge it on a single casino so that you will have more games offered on a single brand name. The games is obviously share same theme and it will be perfect to be running on one casino.

I really like this fresh idea of games but as @seoincorporation pointed out, It’s very hard to trust the game like this which is just a PVP much while you hold the prize pool in your wallet. You are new in the forum so I doubt user can trust to place any bet on this PvP game.

The game is very nostalgic and same idea with the old FishvsFish before which 2 sides compete by putting BTC on each wallet. This is a team effort game which is why it’s exciting to play rather than a single betting competition.

People who like to use martingales and to bet more and more, will be seduced by that game. Well it's the same thing in wagering tournaments but at least you don't lose all your money if you are not the winner in this kind of tournaments. I don't like very much those games actually because we never know when the owner or one of his friend is playing. And if he is losing he could simply say something went wrong, and cancel the round, but it wouldn't be fair.

hello jackmurray

I was testing your betting engine, and you didn't sanitize the betting input, that way users can create a game with invalid data resulting in the loss of their money if they place a bet.


And I don't like the fact that your coins are under your custody because at any moment you can walk away with the money. It would be nice if that could be controlled by a smart contract or a third party.

But a big +1 for making the project open source.

In this game, up to 100 players are gambling on who has more resources.

Players can make a bet or raise their bet at any time.

The game ends when 144 bitcoin blocks have passed without a raise. This will take appoximately one day.

The player who has contributed the most money to the pot at the end of the game wins the whole pot, minus a 2% fee for the host.

In the case of tie, funds are distributed equally and any fractional remainder is left with the host.

My host can be found at https://coinballer.net/ as well as a link to the source code.

We hope you enjoy!

Kind regards,
Jack Murray
