Theoretical Outputs Only
Every number generated by the calculator, the simulator, and the payout tool on this site is the result of a mathematical model applied to standard roulette constants. Theoretical outputs describe averages, distributions, probabilities and exposures. They do not describe the future. Treat any number on this site as an explanation of structure, not as a forecast.
Not Financial Advice
Nothing on this site is financial advice. The tools do not assess your individual financial situation. They do not recommend any wager. They are not investment guidance. Any decision involving real money should be made with appropriate professional advice and a clear understanding of your own circumstances.
Not Gambling Advice
This site does not advise anyone to gamble. It does not recommend specific strategies, specific casinos, specific stake sizes or specific session lengths. It explains how the Martingale system works and where it fails. The point is education, not encouragement.
Not a Prediction Tool
The simulator generates random independent spins using a standard random number generator. The calculator produces theoretical probabilities derived from the rules of European, French and American roulette. Neither tool predicts the outcome of any specific spin at any specific table. Predictive use is impossible because the underlying process is random.
Random Roulette Outcomes Cannot Be Predicted
Roulette outcomes are independent random events. The wheel has no memory. A long run of red does not increase the probability of black on the next spin, and a long losing streak does not make a win "due". Believing otherwise is the gambler's fallacy. The math on this site assumes independence because that is how real wheels behave.
Past Spins Do Not Affect Future Spins
This is the same point worth repeating because it is the most common misunderstanding in roulette. Each spin is independent. The probability of red on the next spin is the same regardless of the history of previous spins. No betting system can change that, including Martingale, Fibonacci, Labouchere, D'Alembert or any other progression.
Calculator Limitations
The Martingale calculator uses a simplified model of the system. It assumes standard even-money bets, independent spins, no table limit unless set explicitly, and no rule variations beyond La Partage and En Prison being not assumed by default. Real casino conditions can differ. The calculator is a teaching aid, not a casino-floor planner.
Simulations Are Educational
The strategy simulator is a Monte Carlo learning tool. It is not connected to any live game. Its results do not represent specific casinos, dealers or tables. Many runs of the simulator produce a distribution of outcomes that illustrates how variance and house edge interact, which is its only intended purpose.
User Responsibility
By using this site, the reader accepts that all decisions about real money play are their own responsibility. The site provides educational content. It does not accept responsibility for losses or other consequences of using betting systems in real casinos. Anyone uncertain about whether to use a betting system at all should default to not using one.
Legal Age and Jurisdiction
Gambling is restricted by age in every regulated jurisdiction and by law in many places. Anyone who plans to gamble must verify that they meet the legal age requirement and that gambling is legal in their country and region. Visiting this site does not authorize any reader to gamble where it is not legal for them to do so.
