A fast three-step workflow
How to use the roulette 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
Test red/black, odd/even, dozens or a straight number on a real 37- or 38-pocket model. Compare flat betting with Martingale, reverse Martingale, Fibonacci, D’Alembert and 1-3-2-6 without risking money.
How the calculation works
A seeded random generator selects an actual wheel pocket on every spin. Zero and double zero lose outside bets; winning wagers receive the displayed standard payout. Progressions alter stake sizing but never alter pocket probability.
Compare how wheel type, wager type, bankroll, limits and stake progression affect a long simulated session.
Formula references
The method is documented against these primary or first-party technical 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.
