Strategy Guide
Negative Progressions
Martingale doubles after each loss (exponential escalation). Fibonacci follows the sequence (1,1,2,3,5,8...), a slower climb. D'Alembert adds 1 unit per loss, the gentlest. Labouchere uses a cancellation sequence with moderate escalation.
Positive Progressions
Paroli doubles after wins (max 3), capitalizing on streaks with only 1-unit risk. 1-3-2-6 uses a fixed 4-step sequence: losing at step 3+ still profits or breaks even.
The Truth About All Strategies
No betting strategy changes the expected value. The house edge applies to every bet regardless of pattern. Strategies only reshape the distribution of outcomes — more frequent small wins vs. rare catastrophic losses, or vice versa.
