Provably fair

A provably fair game commits to its outcome before it knows your stake, and gives you enough information afterwards to prove it did. No trust required, and none asked for.

• Server seed — a secret value we generate. You get its hash up front, which is a fingerprint we cannot change our mind about.
• Client seed — a value from your side. You can set it or reroll it whenever you want.
• Nonce — a counter that goes up by one with every bet on the pair, so no two rounds share a combination.

The result comes from those three values and nothing else. Not your balance, not your stake, not your history.

1. 1
   We hash the server seed and publish the hash. The outcome is now locked in.
2. 2
   You bet, with your client seed and the current nonce attached.
3. 3
   The game combines server seed, client seed and nonce, and derives the result.
4. 4
   When the seed pair is rotated, the server seed is revealed.
5. 5
   You hash the revealed seed and compare it with the hash from step one. Same hash, same seed, honest game.

Every casino bet carries its hashes with it. Open a bet in your account or in the live feed and the hashes are on the record, alongside the game, the stake and the payout.

• Provable fairness applies to our Originals. Games from outside studios run their own certified random generators and are audited by their own testing houses.
• It proves the result was not tampered with. It does not remove the house edge — see what is RTP.
• It says nothing about how much you should stake. That part is on you: read responsible gambling.
