Decision Review

Martingale

Betting systems choose your stake; playing strategies choose your action. Combine one of each in Simulation. These presets do not count cards or establish an advantage. Pros describe useful comparisons, not promises of profit.

All strategies

Bet sizing · Established progression

Martingale

How it works

Double the previous opening bet after a net loss; reset to one unit after a net profit. Hold after break-even.

Example: With a $10 unit, loss → loss → profit gives next bets $20 → $40 → $10.

Pros

Simple rules; short losing sequences can be followed by recovery.

Cons

Stakes grow rapidly. Limits, split losses and partial payouts defeat the idea of guaranteed recovery.

Shared simulator rules and table limits

Simulator conventions: a unit is your base bet. Progressions use the complete round’s net result, including splits and insurance. They continue through cycles until the requested round count or an unaffordable bet. Opening bets are capped at the table limit. Martingale and D’Alembert update from the capped stake. Fibonacci stops advancing at the first sequence value reaching the cap, then moves back normally on profit; no hidden debt builds beyond the cap. Splits and doubles can add exposure. These adaptations differ from systems designed for even-money bets and fixed win goals.

Choosing a preset keeps your other settings and custom decisions. Custom decisions take priority; use Reset to basic strategy to clear them and restore the basic playing preset. Insurance is controlled separately. An unavailable custom action falls back to the selected playing preset.
