D’Alembert Roulette Strategy – The System Explained and Analysed
The D’Alembert roulette strategy was created by French mathematician Jean-Baptiste le Rond d’Alembert in the 18th century. Known for his complex mathematical ideas, d’Alembert designed this system as an alternative to the Martingale strategy, aiming to minimise its flaws.
While it reduces the risk of rapid losses, no strategy is foolproof against a long losing streak, a challenge all betting methods face. D’Alembert’s system offers a more balanced progression but, like any strategy, cannot guarantee immunity from prolonged losing sessions.
What Is the D’Alembert Strategy All About?
D’Alembert’s betting method is progressive, adjusting based on the previous round’s outcome. After a loss, the player’s bet increases by 1 unit, and after a win, it decreases by 1. To start, players must choose their initial stake and unit value.

A Practical Example of the System.
We’ve chosen to illustrate a positive win to loss ratio by way of example to give you an adequate point of reference. In the table below, you will notice that the highlighted rows, representing the winning rounds, are four while the losing rounds are only three.
| Round | Bet | Outcome | Profit |
|---|---|---|---|
| Round 1 | £2 | Win | £2 |
| Round 2 | £1 | Lose | £1 |
| Round 3 | £2 | Win | £2 |
| Round 4 | £1 | Lose | £1 |
| Round 5 | £2 | Lose | £2 |
| Round 6 | £3 | Win | £3 |
| Round 7 | £2 | Win | £2 |
As you can see, the first bet results in a positive outcome and £2 is won. That means in the next round, the hedging properties of the system kick in and the bet is 2-1 = £1. This one bet is not successful, therefore, in round number three the wager placed is again 1+1 = £2. The same pattern continues until the 7th and final round. Although the given example is given in the context of favourable circumstances, it’s important that using this system, players turn a profit even when the number of win rounds equals the number of lost rounds.
D’Alembert vs Martingale vs Fibonacci: Which Strategy Succeeds Where?
The D’Alembert system was created to address the flaws of the Martingale strategy, offering a more balanced approach. At the same time, another notable betting method, the Fibonacci roulette strategy, also provides a structured alternative.
Did D’Alembert successfully strike a balance between minimising risk and securing steady profits? To truly evaluate its effectiveness, it’s essential to compare all three systems—Martingale, Fibonacci, and D’Alembert—and see how each handles risk and reward in roulette.
| Roulette Strategy | Type | Limitation | Recommended Bets | Potential Winnings | Risk |
|---|---|---|---|---|---|
| D’Alembert | progressive | Low Table Limit | Even Bets | Average | Long Losing Streaks |
| Martingale | progressive | High Table Limit | Even Bets | High | Long Losing Streaks |
| Fibonacci | progressive | High Table Limit | Even Bets | Average | Long Losing Streaks |
Similar to Martingale and Fibonacci, the D’Alembert strategy involves placing even-money bets like red/black or odd/even and increasing the bet after a loss. However, unlike Martingale, D’Alembert’s more gradual progression means your wager size won’t skyrocket, even after several losses.
As a result, it requires less capital to play, making it suitable for players of all experience levels and bankrolls. This balanced approach offers a lower-risk alternative to other progressive strategies, providing more control over your bets without overwhelming your bankroll.
Main Advantages and Disadvantages of the D’Alembert System.
Keep in mind that the house always has an advantage when playing even-money bets, despite them appearing to have a 50% win rate. This is because the zero (0) sectors don’t count towards any of the even-money bets, such as red/black or odd/even. This small edge is the downfall of all strategies that rely on even-money wagers
- if wins/losses are 50/50, you turn a profit.
- Highly customizable (many variations)
- Economic and player-friendly
- Vulnerable against long losing streaks
- The hedging aspect cuts total profit
- Can’t neutralise house edge.
While D’Alembert’s betting method is appreciated for its simplicity and balanced approach, it’s important to proceed with caution. The gradual increase in bet size may feel manageable, but the system still doesn’t overcome the house edge.
Even though the possibility of ending up a small winner when wins and losses balance out is tempting, players must remember that no strategy guarantees consistent profits. Modified versions may sound appealing, but the inherent risks remain, and relying too heavily on the system could lead to significant losses over time. Responsible gambling is key
How to Play the Reverse (Contra) D’Alembert Strategy?
To address one of the disadvantages of the standard D’Alembert system, the reverse D’Alembert method takes a different approach to wins. Here, players increase their bet size after each win, aiming to capitalise on a winning streak.
However, caution is still necessary, as no strategy guarantees success. To play this way, you’ll need to follow a few structured steps, gradually increasing your bet to take advantage of potential winning runs while maintaining control over your bankroll. Always keep responsible gambling in mind when using this method.
- Determine the size of one unit of bet
- Choose how many units your first bet will be
- Add one unit to your next bet after winning and subtract one unit after losing
- Aim for an equal number of wins and losses (or better) to cash in a profit.
Test the D’Alembert Strategy with Real Money
While strategy is important, the casino you choose plays a crucial role in your game. Ensure the casino is licensed by the UKGC and promotes responsible gambling. Look for trusted payment methods for safety and security.
Always read the terms and conditions before claiming any bonuses. Most new players can benefit from welcome offers, providing extra funds to test your strategies, but understanding the bonus requirements is essential before getting started.
D’Alembert Roulette System in Summary
If you’re thinking about trying the D’Alembert strategy, it’s important to proceed with caution. Low-stakes live roulette tables are ideal for practice, but remember, no strategy is foolproof. While D’Alembert offers a structured way to manage your bets, its risks shouldn’t be ignored.
Consider starting small and adjusting based on your comfort level. For higher-stakes players, mixing strategies can help spread risk, but always be aware that losses can still accumulate. As with any system, responsible gambling is key to ensuring an enjoyable experience without risking too much.
