The game, the way it is described, is not provably fair for investors, as well as for players. I'll leave this post here and let you guys try to figure out why. (And if my post gets deleted, I will start a new thread.) It will have provable results, which is not the same.

*edit* Okay, someone else beat me to it. Exactly as a previous poster has described. The other way is to pause the game for everyone else just 1 second (or a time they can't notice) and calculate the desired bet ID needed for the win, then resume, grab that winning bet, and continue as if nothing happened.

It can be programmed in the server to do this transparently, and if no winning bet is found within 0.01 seconds, you can just skip it and try again later, attribute it to variances in lag.

Therefore, my statement is that it is not provably fair for investors, and it is also not provably fair for players. You might as well make it at least provably fair for players, and let investors take the chance that the site operators will not cheat.

Like the other guy said, I am not accusing anyone of anything, just that the way this is implemented is not provably fair for everyone.
