Provably Fair

Every game result on CrustyBets is determined by three inputs: a server seed, your client seed, and a nonce (game counter).

Before you play, we show you the SHA-256 hash of our server seed. This is our commitment — we can't change the seed after you see the hash. After you rotate seeds, the old server seed is revealed so you can verify every game.

Result = HMAC-SHA256(serverSeed, clientSeed:nonce) → first 32 bits → float [0, 1)
