Rising multiplier game with real-time cashout
Step-by-Step Guide
- 1
Place your bet before the round starts. You can optionally set an auto-cashout multiplier.
- 2
The multiplier starts at 1.00x and rises continuously — slowly at first, then accelerating.
- 3
At any moment, the multiplier can crash to zero. The crash point is predetermined before the round.
- 4
Click Cash Out to lock in your current multiplier. Your payout = bet × multiplier at cashout.
- 5
If the multiplier crashes before you cash out, you lose your bet entirely.
Provably Fair System
The crash point is computed as max(1, floor(0.96 × 2^52 / (hash_value + 1)) / 2^32), where hash_value is derived from HMAC-SHA256(server_seed, client_seed:nonce). The 0.96 multiplier enforces the 4% house edge. The server seed hash is committed before each round, and the full derivation is verifiable after seed rotation.
Visit the Fairness Verification page to verify any past round with your seeds.
