Roulette is a thrilling game of chance that has captivated players for centuries, thanks to a strategy known as the D’Alembert. 

The technique was derived after the French mathematician Jean-Baptiste le Rond d’Alembert. In this guide, we will explore the D’Alembert Strategy in detail, providing you with a roadmap to master this balanced betting system in roulette.

But first, let’s learn how a mathematician developed such a system.

Origins of the D’Alembert System

The D’Alembert Strategy is often associated with d’Alembert due to its name, but there is no definitive evidence that he explicitly created or endorsed this betting system. The strategy might have been attributed to him posthumously as a tribute or as a way to honor his contributions to mathematics and probability theory.

It’s important to note that d’Alembert was an influential figure in the 18th-century Enlightenment movement, where scholars explored various scientific and philosophical concepts. Probability theory and the analysis of games of chance were subjects of interest during this time. Therefore, d’Alembert’s mathematical insights influenced the development of betting strategies like the D’Alembert Strategy.

Regardless of whether the French mathematician developed the system or not, the method is still an important piece in making a winning game plan in roulette.

D’Alembert Strategy: What is It?

The D’Alembert Strategy is a straightforward and conservative approach that aims to minimize losses and secure small, incremental wins. Its core principle revolves around adjusting your bet sizes based on wins and losses. By doing so, the strategy helps create a balanced progression while mitigating potential risks.

To get started, simply follow these key elements:

Even-Money Bets

The system is commonly used with even-money bets in roulette, such as Red/Black, Odd/Even, or High/Low. These bets offer nearly a 50% chance of winning.

Betting Unit

Establish a comfortable betting unit, which serves as the foundation for adjusting your bets throughout the progression. Starting with a conservative unit allows for a reasonable progression while minimizing potential losses.

Getting Started

To implement the D’Alembert Strategy, players must first learn to do a simple progression based on wins and losses.

In other words, whenever a player loses, they must increase their bet size by one unit. The objective of this incremental increase is to recover the previous loss gradually. Otherwise, decrease the bet size by one unit to protect the winnings and reduce potential losses.

To execute the strategy, follow these simple steps:

  1. Start with your initial betting unit.
  2. Place your bet on an even-money bet of your choice.
  3. After each round, adjust your bet size based on the outcome. Increase by one unit after a loss, decrease by one unit after a win.
  4. Continue this progression until you reach a predetermined profit goal or decide to end your session.

And in each gambling session, it is also important to consider your bankroll so as to:

  1. Set a Loss Limit: Determine the maximum number of units you are willing to lose during a session. If you reach this limit, consider ending the session or taking a break to prevent further losses.
  2. Establish a Profit Goal: Set a realistic target for the number of units you aim to win. Once you achieve this goal, evaluate whether to continue playing or adjust your strategy.
  3. Account for Table Limits: Ensure the table you are playing at has betting limits that accommodate the progression of the D’Alembert Strategy.

In applying the method to its fullest potential, practice is key. Observe your progress, evaluate your results, and make necessary adjustments. Every player’s experience may differ, so adapt the strategy to suit your playing style and risk tolerance. But if you want to try other strategies, might as well learn the Double Street Quad.

Learn to Set Limits

While the D’Alembert Strategy offers a balanced approach to roulette betting, it’s crucial to be aware of its limitations:

No Guaranteed Wins

Roulette is ultimately a game of chance; no strategy can guarantee consistent winnings. The D’Alembert Strategy can mitigate losses, but it cannot eliminate them.

Slow Progression

The D’Alembert Strategy focuses on incremental wins and losses, which means it may take time to achieve significant profits. Patience is key.

House Edge 

Remember that the single-zero (or double-zero) on the roulette wheel gives the casino an edge. In European roulette (single-zero), the house edge is approximately 2.7%.


The D’Alembert Strategy offers a balanced and measured approach to roulette betting. This strategy aims to minimize losses and secure incremental wins by adjusting your bets based on wins and losses. 

Remember to exercise responsible gambling, never wager more than you can afford to lose, and enjoy the thrilling world of roulette armed with the knowledge of the D’Alembert Strategy.

And while this guide is for informational purposes, roulette remains a game of chance. This means that strategies cannot guarantee consistent winnings. The best way to not squander your resources is to gamble responsibly.
