How Crash works

Place a bet before the round starts. The multiplier rises from 1.00× and grows on a smooth curve. At a random point the round crashes, if you cashed out before the crash, your bet is multiplied by the value at cash-out time. Auto-cashout lets you lock a multiplier in advance (e.g. 2.00× = 2× return triggered automatically).

Strategy & bankroll

The expected value of any cash-out target is identical (99 cents on the dollar), what changes is variance. Cashing at 1.50× hits ~66% of the time and turns small profits into a flat curve. Cashing at 10× hits ~10% of the time but each win is a 10× multiplier of your stake. Fixed-fraction sizing (1–2% of bankroll per round) and a hard stop-loss are the only meaningful protection against tail-risk.

Verifying a Crash round

The crash point is derived from HMAC-SHA-256 of the seed pair plus nonce, mapped through a public formula that gives a 99% RTP target distribution. The seed pair is published the moment the round resolves, recompute and confirm the crash multiplier independently.

FAQ snapshot

Is there a strategy that beats Crash?

No. The 1% house edge is mathematical and provable. Any 'system' that claims to flip the EV is wrong, period. Bet sizing changes variance, not return.

What is auto-cashout?

A pre-set multiplier the system locks in for you. Useful when you want to play many rounds without missing the cash-out window. Same EV as manual.

Can the round crash at 1.00×?

Yes, instant crashes happen ~1% of the time and are part of the published RTP. Auto-cashout at 1.01× still loses the round in that case.

Can two players see different crash points?

No. The crash point is global and identical for every player in the round. Your individual cash-out time decides your result; the crash itself is the same number for everyone.
