Topic: POTLUCKGAME.COM Multiplayer Bitcoin game LAUNCHED!! - page 11. (Read 7052 times)

Hello All!
We have updated potluck with new sign up bonuses. Every new member will get 100bits to try the game. All the existing members also get 100 bits! If you sign up with a promo code, you will get 150 bits sign up bonus!Enjoy the game! and as always we are open for any feedback.

Cheers!

This is how the edge would be in your example:

pot value at the end of the game: 5000 satoshis
your bet: 2500 satoshis
house edge = 1% of potValue = 50 satoshis
your profit = 5000 - 50 - 2500(initial bet amount) = 2450 satoshis (1.98x) return

if you joined potluck with a promo code, then the promo code owner would get a cut too.

promo code owner commission = floor(5% of house edge) = 2 satoshis
final house edge : 50 - 2 = 48 satoshis

There is no fee on the bets.

apart from house edge, the only other fee is the withdrawal fee of 0.0002 BTC (to cover the bitcoin transaction fee)

Does this clarify your doubt? Cheers!

So for now the limit of max bet is 2500 sat? But what I really mean is not about the house edge, because this is bases on pvp games right? I mean about the fee for you guys like how much you guys get on every single bet or every payout? Let say I bet for 2500 sat and the total pot is 5000 so if I win how much is the payout? 5000 sat or 4500 sat based on your 1% house edge if you mean that fee?

Here is exactly how it looked on my end just now:


But I refreshed the site couple times and you are right there is lock indicating secure connection appeared after some time:



Have you changed something?

That is odd. When we visit https://potluckgame.com we are seeing the green lock in chrome browser. We will test the config once again. Thanks for pointing this out.

By HSTS you mean SLL protocol or HTTPS? No, it is not working for me either. I can't see icon indicating secure connection at all.
Since SSL protocol is not only showing on single machine I guess it is a problem with it on your side.

Hey cjmoles,
Thanks for the reply. The highest active users count was 11 on day 1. One thing we have observed is that there is no enough room to try the game with 1000 satoshi signup bonus. We are planning to change this to 100bits. So that players can wager more, win more and also withdraw BTC. We will post a new message once these changes are live.

How's the traffic been so far?  Are there any peak hour statistics so we can figure out the most optimal time to participate?  Those would be some helpful numbers to the devoted gamblers out there since it's a multiplayer game....right?  That'd be sweet if you could include some running numbers for us!

Hey quintuple,
Thanks for the screenshot. We are working on the fix.
HSTS is enabled on the website. didn't it work for you?

Hello All,
Here is an update for provably fair system.


We see the following advantages:

• Server can't predict totalTicketsWithoutLastBetTickets during the first 20 seconds when the game is active.
• Server can't change totalTicketsWithoutLastBetTickets after the game is in 'pause bets' state.

So even if genius player / operator places the last bet hoping to win every time, the last bet will be excluded from the rngSeed calculation. So he/she can not influence the outcome.

I think you need to improve the design a bit, it doesn't scale well at the moment.

Also, no HSTS?

Thanks eternalgloom!
yeah, we are going to design the logo currently, it's not on high priority. But it should happen in a couple of weeks!

Hey Erza,
If there is only one player, then server bot (singSling) will play with you. In order to keep the game provably fair, singSling can't choose any bet amount. It has to match your bet. So if you have 3 bets (100 satoshis each) then singSling will place a bet of 300 satoshis.

Yes, the game launched today we are hoping that people like our game and have fun playing it. The maximum bet per round is 2500 satoshies and there is no limit to max payout. Potluck will never put a limit on max payout.

The house edge is just 1% or less (if the winner belongs to an affiliate program, hen the affiliate owner will get a cut in 1% commission)

Hope this answers your doubts. Cheers!

This is answerred in the OP:

The website looks pretty good, but you might want to add a logo that you can use a favicon

Totally agree with you! and thanks a lot @MartinL for an excellent gist. Provably fair game and high-quality UX are our top priorities. So we will work to find a perfect provably fair solution. Meanwhile, if you find a solution and we use it, we would definitely reward you with some BTC! Stay tuned! we will post another message when we have one. Cheers!

What about if there is only one player? So your bet will be refund or it stay until someone place a new bet? And btw i only saw 3 people online on your site? Does this thing will really affect on your play? And how much is the max bet for each and the max payout?

And is there any fee after each bet done? May be for you guys because i saw that you saying about giving every pot to the winner here

Unfortunately that is not true: Even within the constraints of the maximum bet limit–which can be circumvented by using multiple accounts anyways–it is very easy to find the correct number of tickets to purchase.

This simple proof of concept finds all valid wager sizes with which the last player to join any given round would win. Even for games in which many tickets have already been sold finding a winning ticket is virtually guaranteed.

Your code samples were missing the createHMACHash function, so I had to assume how it works. Let me know if yours doesn't use a SHA256 and I'll update the PoC. I have also modified findWinningTicket to return the winning ticket number directly. Apart from that your code is unchanged.


That would make the calculation slightly more complex but would not change the number of winning tickets one can expect to find.

For the game to be provably fair you essentially have to prove that the house cannot know the game result in time to cheat. One solution to that end is to use a key stretching function for the game result calculation, which would make it impossible to calculate whether a wager will win or not before the game ends. This is detrimental to user experience, though, as players would have to wait for at least the round duration to find out who won the game.

Thanks for your feedback JackpotRacer!
We will have a look at the FAQ section!. Feel free to try the game with 1000 free satoshis.

nice idea but please check your FAQs regarding HE imo there is need of corrections text wise cause it could be misunderstood

good luck

Hey MartinL,

Thanks for your reply!

Here is how the provably fair system currently works. (we are open for any suggestions)

1) when you place a bet, you get the tickets range in response. (visible in my bets section) This is important so that server can't reshuffle the bets in order to win the game.

2) The server doesn't know the winning ticket before the 20 seconds (end of the game). As the total pot value is taken into the random number generator.


3) if the operator places the last bet, his/her tickets will be last in the sequence (tickets distribution starts from 0 onwards). Also, no one can place the bet amount more than maximum bet. So it is extremely difficult to come up with the amount to make the last tickets win.

one way to make it even more difficult is to include the last bet amount into the equation. Something like this:

Let me know what you think.
