Provably fair crash sites you can verify yourself

Provably fair crash sites let you check every round yourself. Before the round, the casino shows you a hash of its secret server seed; afterwards it reveals the seed, and you can rebuild the crash point from it. If the casino had changed anything, the hash wouldn’t match. Our partners Stake, Shuffle and Gamdom all run provably fair crash originals. Here’s how they compare and how to verify a round.
Best provably fair crash sites

How to verify a crash round
- Open the round in the game’s history and view the fairness details.
- Copy the revealed server seed, your client seed and the nonce.
- Paste them into our provably fair verifier or the casino’s own checker.
- Confirm the server seed’s hash matches the one shown before the round.
Algorithms differ by casino, so the casino’s own documentation has the exact formula. Our verifier has a generic mode and a Bustabit preset based on its published code.
What provably fair does and doesn’t prove
It proves the result wasn’t changed after you bet. It doesn’t remove the house edge, which is built into the formula. Read provably fair explained and is Aviator real or fake?.
Pro tip: change your client seed now and then. It’s free and makes your rounds your own.
