Strategy backtester
Replay any flat / martingale / paroli strategy over the last N observed multipliers and see what the result would have been. Past multipliers are not predictive.
What-if simulator
replays your strategy over the last 1000 observed roundsFree Crash demo
The demo is play-money only. Place chips on whichever bets you'd take in the real game, each round resolves against the next spin from the live feed and your demo balance updates. History is tracked locally so you can review every settled bet.
Strategy backtest
The backtest replays your current stake plan against the last N real spins of Crash. Pick a window (50, 100, 200, 500 spins), set a starting balance, choose a progression (flat / martingale / paroli) and a maximum stake multiplier safety cap. The result panel shows P/L, ROI, RTP, win rate, longest win/loss streak, max drawdown and an equity curve. Stop-profit and stop-loss are honoured during replay.
What it isn't
A backtest tells you how a strategy would have done on the recent past — it is not a forecast. Future variance is your own. Use the simulator to develop intuition for stake sizing and drawdown tolerance, not as a prediction tool.
