Every casino round is decided by a seed we commit to before the round starts and reveal after it ends. Nothing about the outcome can be changed in between, and you can check that yourself below — in your own browser, without trusting our server.
Before a round we generate a secret server seed and publish only its SHA-256 hash. The public seed (the round ID) is visible from the start.
Once the round settles, the server seed is revealed. Hash it and it must equal the hash you saw before the round — proof it was never swapped.
Recompute HMAC-SHA256(serverSeed, publicSeed:nonce). Its first 8 hex characters ÷ 0xFFFFFFFF is the roll that produced the result.
For dice, roll = ⌊r × 100⌋ + 1, giving 1–100.
No settled rounds yet.
Pick a round on the left or paste seeds from your own bet history. You can also try any seeds you like — the outcome is deterministic.
