Provably fair

Every result is HMAC-SHA256(serverSeed, clientSeed:nonce). We commit to the server seed by publishing its hash before you bet, and reveal the seed when you rotate — so you can recompute every round and confirm nothing was touched.

Your current commitment

We published this hash beforeyour next roll. We cannot change the seed behind it without breaking the hash — that's what stops us rigging anything.

server seed hash: —client seed: — · next nonce: 0

Rotating retires the current seed and publishes it below, so you can verify every round you played on it. A brand-new commitment starts immediately.

Blackjack tables commit a fresh seed per round— copy that round's seed & hash from the table (revealed when the hand settles) and check it below.
