How the D'Alembert System Works
The Pyramid Method
The D'Alembert system is based on the theory of equilibrium - wins and losses will eventually balance out.
Betting Rules
- After a loss: Increase your bet by one unit
- After a win: Decrease your bet by one unit
- Minimum bet: Never go below your base bet
- Goal: Return to base bet with profit
Example Session (Base: $10, Unit: $5)
- Bet 1: $10 - LOSS → Next bet: $15
- Bet 2: $15 - LOSS → Next bet: $20
- Bet 3: $20 - LOSS → Next bet: $25
- Bet 4: $25 - WIN → Next bet: $20
- Bet 5: $20 - WIN → Next bet: $15
- Continue until back to $10...
Strategy Tips & Warnings
Advantages Over Martingale
- Slower progression - Linear growth instead of exponential
- Lower variance - More manageable bet sizes
- Smaller bankroll needed - Less aggressive system
- Better for long sessions - Can withstand more losses
Important Limitations
- Equilibrium theory is false - Past results don't affect future outcomes
- House edge still applies - No system beats negative expectation
- Slower recovery - Takes longer to recoup losses than Martingale
- Can still hit table limits - With very long losing streaks
Best Practices
- Use small unit increases (10-20% of base bet)
- Set a maximum bet limit (e.g., 10x base bet)
- Play on even-money bets (roulette, baccarat)
- Have a bankroll of at least 50x your base bet
- Set stop-loss limits before starting
