What is the Martingale Strategy?
The Martingale is a progressive betting system where you double your bet after every loss and return to your base bet after a win. The idea is that one win recovers all previous losses plus a profit equal to the base bet.
Why Use a Martingale Calculator?
While the strategy sounds appealing, the math reveals hidden risks. Our calculators show you exactly how much bankroll you need, what your probability of ruin is, and whether the expected value is positive or negative for your specific game and parameters.
Key Insight
Without a bonus or promotional edge, Martingale has negative expected value in every casino game. The calculator helps you quantify exactly how negative — and whether bonus offers can tip the math in your favor.
