Martingale Strategy Simulator

A fast three-step workflow

How to use the martingale strategy simulator

1
Enter the known information
Add only the values or source text the calculation needs. Useful examples and safe defaults are already selected.
2
Adjust the assumptions
Use the extra controls to match your real task instead of accepting a hidden one-size-fits-all assumption.
3
Review the complete result
Check the main answer, supporting values and method before copying, downloading or acting on the result.

What makes this tool more useful

Simulate 10,000 bets from a $1,000 bankroll and a $1 base stake, or change every assumption. Compare famous progressions against flat betting and see how table limits, losing streaks and finite bankrolls change the result.

How the calculation works

Each round is generated from the selected win probability and payout. The chosen progression changes stake size after wins or losses, while bankroll and table-limit checks cap every wager. A Monte Carlo panel repeats the same setup with different deterministic seeds.

Use the simulator to examine volatility, maximum drawdown and ruin risk—not to predict a future outcome or guarantee a profit.

Formula references

Educational simulation, not a winning system

Gambling involves financial risk. Betting progressions change bet size and volatility, but they do not remove the house edge or make independent outcomes predictable. Results are simulated examples, not advice or a promise of profit. Never chase losses; if you gamble, set a fixed entertainment budget and stop when it is reached.

Private, fast and mobile-ready

The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
