Learn all about the D’Alembert Roulette Strategy. This meticulously crafted approach to betting adds a nuanced layer to the classic game of roulette, offering a calculated balance between risk and reward. In this introductory guide, we invite you to explore the intricacies of the D’Alembert strategy, unlocking the potential for strategic triumphs and an enhanced gaming experience at Bet88 Casino.

What is the D’Alembert Betting System

The D’Alembert betting system draws inspiration from the renowned French physicist and mathematician, Jean le Rond d’Alembert, known for his contributions to D’Alembert’s principle. Interestingly, d’Alembert was also a notable gambler, and the betting system bears his name due to his inclination towards the gambler’s fallacy.

In essence, the system addresses the gambler’s fallacy, a misconception where players believe that a specific outcome is more likely to occur on the next spin because the opposite result has appeared multiple times in succession. D’Alembert’s approach counters this fallacy by relying on the principle of eventual equilibrium in even-money bets. Advocating for consistency, players employing this system place the same even-money bet on each spin. The strategy aims to prevent players from being swayed into favoring a particular option based on the mistaken belief that it is “due” to occur.

How Does the D’Alembert Strategy Work

The D’Alembert system offers a simple yet effective approach to roulette strategy, particularly suited for even-money bets like Red/Black, Even/Odd, and 1-18/19-36. Unlike the aggressive doubling of the Martingale system, the D’Alembert method employs a flatter bet progression, making it one of the safest and easiest strategies to execute.

To begin, players must determine a ‘unit,’ representing the base wager amount. This unit should be a fraction of their total funds, typically recommended at 0.50% or 0.33% to ensure prudent bankroll management.

The strategy involves gradually adjusting bets based on game outcomes: increasing after losses and decreasing after wins. Starting with one unit, players add or remove a single unit as needed. This gradual adjustment helps mitigate losses during losing streaks and maximizes gains during winning streaks, creating a balanced and sustainable betting approach. 

The below table will show you how a game will go when you apply this strategy:

Round 53Loss-3
Round 64Win4
Round 73Loss-3

We can see that the number of wins and losses were identical but we still have a profit at the end.

Pros and Cons of the D’Alembert Strategy

Let’s understand the pros and cons of this strategy before applying it in the game.


  • Effective bankroll management tool
  • Simplicity makes it accessible for all players
  • You maintain control over your spending by setting the unit amount


  • Potential for a losing streak, inherent in casino games
  • Unlikely to yield significant winnings, given the nature of the strategy.


The D’Alembert Roulette strategy offers a balanced and systematic approach to playing the game, particularly suitable for even-money bets. Its simplicity and gradual adjustment of bets based on game outcomes make it appealing for players seeking a methodical and low-risk strategy. While no strategy can guarantee consistent wins in the long term due to the inherent randomness of roulette, the D’Alembert system provides a structured framework that can help players manage their bankroll effectively and enjoy a more controlled gaming experience on platforms like Bet88.
