Good to know. I'll keep an eye out for that!

Usually it works if there is an ongoing promotion, which is no longer the case in this thread.

Does posting addresses in threads like these ever work? I love it.

To make it fair (the hourly game):

1) generate a digit ranging from 0 to 9.
2) make the system do this 4 times (so it generates 4 digits seperately in 4 steps, instead of generating a 4-digit number in 1 step).
3) the 4 digits together now for a number 0000-9999 (number 10.000 would be gone but number 0000 could be used as jackpot).

Use 1 Server Seed Hash (SHA-256) and 1 server seed per game (so not per digit, but per 4 digits) but do make 4 different client seeds (1 for each digit) per game. So all the 4 digits can be generated using the same "key", just using a different client seed for each digit.

Also, the client seeds should be generated in a way that the client seed of one digit will not influence the generation of a client seed of a next digit for that same game, ofcourse. 

And if possible, give more transparency on how the calculations are exactly done. Hashes converted to numbers, how it's done. By not knowing the server seed before the game, there's no way that would cause any harm i suppose ?


What i typed here is ofcourse still not 100% proof of fair play but i still have my doubts, like many others, on how the number is currently generated and there are possible ways to manipulate it in order to never (or barely) hit the jackpot. This 'method of generating' i wrote is still absolutely NOT legit or finished to be used, but might be a start to a provably fair game that makes people more certain they play something... fair. Hitting the jackpot right now just doesn't look like a 1/10.000 chance. Who can tell anyway? I'm not a scripter but i hope, in case you truly want your game to be provably fair to everybody, you will use a system like this and have a game where every number created, has an equal 1/10.000 chance of being created. And if that means the jackpot should contain less money for you to make some profits, that's fine by me. We all understand you can't give away more BTC than what the advertisement etc pays you, and respect a fair cut that goes to you in proportion to the work you put into this. Yet don't forget about the people making this happen for you :-) some more transparency would be very appreciated so we can all enjoy this game even more without questions being raised!

Thank you very much

I can play with adblock on, is it meant to be like that? I can remember some time ago it wasn't possible.

Well, the server and client seeds are 2 randomly generated strings that are generated before you make your roll. Yes, it would be ideal to let users enter in their own personal client seed to make it airtight but atm that would add a whole new level of complication to the code. I am however working towards doing that but won't be able to do it next week when I add the provably fair for free play.

I'm playing for few weeks now quite a lot and I don't have your luck, Rolled 9886+ 2 times out of 100+ maybe even 200+

But could it be possible to exclude big wins at all? Not that I doubt your integrity or anything but neither me nor any of my referrals did roll anything real or close to 10000 even once, lol...

This was one of the reasons I went for advertising (to see with my own eyes someone winning big time)

Yes, it depends on both the client and server seed (only the hash of which is shown before the roll).

As I got it the rolled number depends on both the server and the client, so it is not possible to throw away all potential big wins before you click ROLL, right?

this would be great as I have had questions about the free play roll too.  thanks wetsuit you seem really responsive and to be running a reputable free bitcoin site, which is so rare nowadays.

Well showing you the seeds in advance means that the generated number cannot be changed mid-way after you click ROLL. Note down the server seed hash, client seed and nonce before you play and after playing, note down the server seed of the previous roll. Then if you generate a SHA 256 hash of the server seed, it should match the server seed hash that was shown, meaning that the server seed wasn't changed after you clicked ROLL.

Then, using the formula on that page you can use the server seed, client seed and nonce to calculate the number that should have been rolled and then compare it to the number that was actually rolled, and if both match then you have confirmed that there was no foul play.

I'm not very good at explaining stuff but I hope this made it a bit clearer.

That's great, thanks ! By the way, could you explain how a 'seed' is proving fair game ? Because I don't understand how showing a seed for the next game proves anything when only the creator knows the algorithms to 'solve' the seed. Not that i doubt the system, i suppose it works as many sites use it, but for me (= a noob when it comes to scripting) it shows as much as posting a picture of a cat with a subtext "provably fair game, see fluffy cat image"

Yup, I can do that. It is actually on my list of stuff to do. Give me a week to implement it.

Hi,

I really like your site, but could you make the hourly 'Free Play' game also provably fair ? The game is great because of the chance to win 0.2 or 0.02 bitcoins but I don't see any real proof that you can actually win this at a fair 1/10000 and 2/10000 chance ? And without the top wins included in the game, there's no fun to it...

How do we know the number is generated in all fairness ?

I've been playing the hourly game many times a day for a while now and I seem to be having a number between 9886 - 9985 (earning you 2203 Satoshi) quite a lot (about 1 time out of 10 !!!) even though that's far more than the mathematical chance of 1 time out of 100 !!! Makes me believe that you silently increase the chance to win 2203 satoshi for making the game more popular... I'm wondering if you silently decrease the chance to win higher amounts too, otherwise you would not be able to make any profit out of your site...

And I know about the stats of payments shown on the site, but that doesn't prove the fairness of how the number is generated. So please show me i'm wrong by adding such an system to the site, as i love the concept of bitco.in !
