The D’Alembert Betting Strategy is a popular method among gamblers looking for a more balanced and less aggressive approach compared to the Martingale system. Developed by the French mathematician Jean le Rond d’Alembert, this strategy is based on the idea that wins and losses will eventually balance out over time.
How Does the D’Alembert Strategy Work?
The D’Alembert system follows a negative progression approach but in a more controlled manner than the Martingale. Instead of doubling your bet after a loss, you increase your bet by one unit. After a win, you decrease your bet by one unit.
Example:
- Start with a $10 bet.
- If you lose, increase your next bet to $20.
- Lose again? Increase to $30.
- If you win at this point, decrease your next bet to $20.
- Continue increasing after losses and decreasing after wins.

When to Use the D’Alembert Strategy
The D’Alembert system works best with even-money bets, such as:
- Roulette: Betting on Red/Black or Odd/Even.
- Baccarat: Betting on Player or Banker.
- Blackjack: Flat betting on individual hands.
Advantages of the D’Alembert Strategy
- Low Risk: Unlike Martingale, the progression is slower, reducing the risk of massive losses.
- Easier Bankroll Management: The gradual increase and decrease in bet size make it more sustainable.
- Better for Longer Sessions: The system is less likely to wipe out your bankroll quickly, allowing for extended play.
Limitations of the D’Alembert Strategy
- Chasing Losses: Although more controlled, it still relies on recovering losses over time.
- Short Streak Vulnerability: Consecutive losses can still accumulate, and you may struggle to break even if wins and losses alternate frequently.
- Potential for Slow Recovery: Unlike Martingale, it may take more time to recoup losses due to its gradual progression.
Does the D’Alembert Strategy Work?
The D’Alembert system is suitable for players who prefer a steady and cautious approach to betting. While it doesn’t guarantee consistent wins, it helps mitigate the impact of losing streaks without the rapid escalation of bets seen in the Martingale strategy. When used responsibly, it can be a strategic way to enjoy even-money games with lower risk.
Final Thoughts
The D’Alembert Betting Strategy is a practical choice for those who want to combine strategic betting with manageable risk. It works best when you set clear limits and keep track of your bet adjustments. As always, gamble responsibly, and never chase losses beyond your comfort zone.
