Crash game
A game where a multiplier rises from 1x until it crashes, and you must cash out before the crash to win.
In a crash game, each round starts at 1.00x and a multiplier climbs. The crash point is decided before the round starts. You win your bet times the multiplier if you cash out (manually or automatically) before it crashes, and lose your bet if you do not.
How results are generated
At provably fair casinos, crash points usually come from a precomputed chain of hashes rather than from each player's own seed, because all players share the same round. The casino publishes the hash of the final element of the chain before the game starts, and each round's result can be checked against it, often combined with a public value such as a future block hash. Implementations differ, so check the casino's own documentation.
Why it matters
Crash is fast and social, which makes it easy to play many rounds. The house edge is usually built in by a small chance that a round crashes instantly at 1.00x, plus the payout formula.
Worked example
You bet $10 with auto cash-out at 2.00x. If the round reaches 2.00x, you receive $20. If it crashes at 1.73x, you lose $10.
