How the result is calculated
float[i] = HMAC_SHA256(server_seed, "client_seed:nonce:cursor"), 4 bytes per number 0 ≤ f < 1 crash = max(1.00, floor(99 / (1 − float[0])) / 100), capped at ×1,000,000. The chance the rocket reaches multiplier x is 99% / x. Hence 99% RTP with any strategy. Payout is capped at ×10,000: at that multiplier the bet cashes out by itself. Bet up to $10,000 ÷ multiplier, at most $5,000.
How a round works
- Waiting for a bet. Pick an amount and, if you like, an auto cash-out.
- Bet accepted. The server locks in your bet and the round’s crash point — its hash is in the “Provably fair” tab. A second later the rocket launches.
- Flight. The multiplier climbs. “Cash out” pays bet × the current multiplier.
- Crash. If you didn’t cash out before the crash, the bet is lost. After a cash-out the flight fast-forwards so you can see where it would have crashed.
Bet up to $10,000 ÷ multiplier, at most $5,000. Auto cash-out goes up to ×10,000 and the payout never goes higher: the rocket cashes out by itself. The ½, 2× and “Max” buttons only change the amount.
