Provably Fair
You don't have to trust us — you can check. The outcome of every round is locked in with a cryptographic hash before you play, and revealed after so anyone can confirm it was never tampered with. No scam can survive math this open.
1. Commit (before you play)
The server generates a secret random seed and publishes only its SHA-256 hash. The outcome is locked in — it physically cannot be changed without breaking that hash.
2. Play with your seed
You add your own client seed and a nonce that counts up each round. Your input is mixed in, so neither side can control the result alone.
3. Reveal & verify (after)
When seeds rotate, the secret server seed is revealed. Hash it yourself: if it matches the hash shown earlier, the round was honest. Then re-derive the crash point with the formula below.
Verify a round yourself
Paste the values from any completed round. This runs the exact same public formula and tells you whether the revealed seed matches the committed hash, and what crash point it produces.
The exact formula (nothing hidden)
This is the same algorithm published in our casino integration docs. Run it in any language and you'll get the same result we do:
serverSeedHash === sha256(serverSeed) h = first 52 bits of HMAC_SHA256(serverSeed, clientSeed + ":" + nonce) fair = floor((100 * 2^52 - h) / (2^52 - h)) / 100 crashPoint = max(1, floor(fair * (1 - houseEdge) * 100) / 100)
Distribution: the probability a round reaches multiplier m is about (1 − houseEdge) / m. The minimum result is always 1.00x.
