Provably fair games

Play with confidence! We guarantee that every game you play at Bitcoin Games is completely fair. You will be dealt a completely random deck of cards every game, and we can provably demonstrate that we have in no way manipulated the shuffle.

Instead of just taking our word for it, we make available all of the information you need to verify that our game is fair.

The reason that we can guarantee this is that your web browser supplies a random number that we must incorporate into the random number generator in a provably consistent way. Our server first shuffles the deck, and your computer then gives us a random number that we must use to repeatedly cut the deck. Since our servers do not know what random number your computer will send, we have no way of knowing how the shuffle will look in the end.
