Crash X calculators
These calculators use Crash X's published 96% RTP, so every unit you wager costs 0.04 on average whatever target you pick. Targets can go as high as the x999,999 ceiling, but reaching it is roughly a one-in-a-million event per flight, and your casino's own payout limit may cut a big win short. If you play both bet buttons, enter the combined stake: two bets per round double the turnover the edge applies to.

Session cost calculator
The house edge applies to every unit you stake. This is the long-run average; a single session can end far above or below it.

Expected return
96.00
The house edge is 4.0% of every unit staked, so 100 rounds at 1.00 cost 4.00 on average. Winning rounds do not reduce this: the edge applies to the total you put through the game.
Losing-streak calculator
How likely is a run of misses at your target? Worth checking before trying any doubling system.

Units a doubling system loses
255
Aiming for 2.00x, the chance of 8 misses in a row at least once in 200 rounds is 39.9%. A system that starts at 1 unit and doubles after every miss has lost 255 units by the end of that run.
Every calculator uses the published RTP of 96% and the same model as the methodology page. They show long-run averages and probabilities, not predictions. RTP & Fairness · Methodology
