Crash

About

Crash is a real-time multiplier game. Each round, an increasing multiplier ticks up from 1.00x; you can cash out at any moment. If the multiplier 'busts' before you cash out, you lose the stake. Bust points are pre-committed to a server seed before the round starts.

How a round plays

• Place a bet in your chosen asset before the round starts.
• The multiplier begins at 1.00x and climbs in real time.
• Cash out at any point to lock in stake x current multiplier.
• If the round busts before you cash out, the stake is lost.

Provably fair

• Each round derives its bust point from HMAC-SHA256(server_seed, client_seed || nonce) - committed before the round, revealed after seed rotation.
• You can rotate your client seed at any time; the next round uses the new value.
• After rotation, the verifier app at /verifier reproduces every round you played from the revealed server seed + your nonces.

Every round is verifiable from a server seed (revealed after rotation), your client seed, and a per-round nonce. See how it works for the full construction.
