Verifying a Game Result
Step-by-step checks for confirming a past game result yourself.

server seed, client seed, nonce, hash, RNG, riggedChecking a result needs the server seed out in the open, and the seed in use right now is still secret. So verification always ends with a rotation.
- Before playing, note the server seed fingerprint shown in Settings, under Fairness.
- Play as normal.
- Rotate your seeds from the same page. The old server seed is revealed.
- Hash the revealed seed with SHA-256 and compare it to the fingerprint from the first step. Any online SHA-256 tool works. A match proves the seed was never swapped while you played.
- Recompute the results. The Provably Fair page on the main site carries a calculator for each game: give it the revealed server seed, your client seed, and the nonce of the bet, and it rebuilds the outcome step by step.
The nonce counts your bets under the current seed pair, starting from zero. One round consumes one nonce, with two wrinkles: opening several cases at once consumes one per case, and a blackjack hand consumes a single nonce for everything in it, splits and dealer cards included.
If a recomputed result ever disagrees with what happened in the game, that is what this system exists to catch. Open live support with the seeds and the nonce to hand.
