Provably fair

Every round is committed before it starts and revealed after it ends, so the crash point can never be changed once bets are open.

Before betting opens, the server publishes a commit hash of its secret seed.
You and other players contribute client seeds during the round.
After the crash, the server reveals its seed; the SHA-512 combination yields the exact crash point.

Verify it yourself

Open the in-game provably-fair verifier to recompute any round's crash point in your browser from the revealed seeds.
