Live demo & backtest
Place practice bets against the live feed using a demo balance, or replay a fixed allocation across the last N spins to see how it would have done. Balance and bet history persist across reloads.

Click a number to place the active chip; right-click or the × on hover removes it. A number hit pays stake × multiplier (the lightning multiplier of that round). Upstream exposes the landed number only on bonus rounds — plain leaf rounds without a number count as a loss for number bets.
Free Lightning Storm 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 Lightning Storm. 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.
