Don't take our word for it. Check it yourself.
Every result comes from a server seed, your client seed and a bet number. We lock in the server seed before you bet and show it when you rotate, so you can re-run any round here in your browser and get the same answer.
Server seed
We generate a random 32-byte seed and show you only its SHA-256 hash. The seed itself stays sealed until you rotate — so we cannot change it once you have the hash.
Client seed
Your half of the entropy. Set it to anything you like at any time. Because it is mixed into every HMAC, we cannot predict outcomes without knowing your choice first.
Nonce
A counter that increments with every wager on the current pair. Same seeds, different nonce, completely different outcome — and every round stays independently checkable.
