Provably fair, not "trust us"
Every single round gets its own random server seed, hashed and shown before the round starts. Once the round is settled the seed itself is revealed, so you can recompute the result on your own machine. House modes (Crash, Upgrader) run on a fixed 4% edge; player-versus-player modes (Coinflip, Colors) take a flat 5% per side instead.
Fresh seed per round
Each round generates its own random server seed and publishes only SHA-256 of it. The commitment is stored before anything is rolled.
You set the client seed
Your seed is mixed in. Because you control it, we can't precompute a result that works against you.
Nonce counts up
Every round increments a nonce, so results stay deterministic and can never repeat by accident.
Reveal and verify
When the round settles, the server seed is revealed in your history. Hash it, compare with the commitment, then reproduce the roll.
Your seeds
There is nothing to rotate: the server seed is new for every round and revealed as soon as that round finishes.
Manual verifier
Paste any revealed server seed, the client seed and the nonce. This runs SHA-256 in your browser — the exact same function the games use.
