Crash Lab
Test a crash strategy on thousands of simulated sessions. See how often it ends ahead, how often it loses the whole bankroll and what it costs on average. Everything runs in your browser. No money, no prizes.
Simulator
How the simulator works
Each round draws a crash point from the standard crash-game law: the chance of reaching a multiplier x is RTP ÷ x. Your bet wins if the round reaches your target and loses otherwise. A session ends when its rounds run out, when the bankroll can no longer cover the base bet, or when it reaches the profit you set with “stop when up by”.
- Fixed cash-out: the same bet and target every round.
- Martingale: after a loss the next bet is multiplied so that a win recovers the losses plus one base bet (×2 at a 2x target). After the maximum number of doublings the loss is accepted and the bet resets.
- D’Alembert: one base unit more after a loss, one less after a win.
- Paroli: the bet doubles after a win, up to three wins in a row, then resets.
- Two bets: two base bets every round at two different targets.
The random numbers come from a seeded generator, so the same settings and seed always reproduce the same run, and a copied link shows others exactly what you saw.
How to read the results
- Sessions ahead can be high for short sessions or with a “stop when up” rule. That rule turns many small wins into finished sessions and leaves the losing ones to run on; it changes how results are spread, not the average.
- Average result converges to 3% of the total staked, whatever the strategy. Compare it with the line “the house edge predicts”: with enough sessions the two match.
- Lost whole bankroll is the tail risk that systems like the Martingale trade for frequent small wins.
What it cannot tell you
Real games may use a different RTP, a maximum win, or other rules; check the game’s info panel and adjust the RTP field. The simulator does not predict real rounds, and no simulator can: each round of a real game is decided independently. It exists to show why no betting pattern beats the house edge.
