If you are looking for a low-risk betting strategy, then you should consider the D’Alembert method. D’Alembert betting strategy, like many others, tends to offer small wins but can lead to significant losses. It involves increasing bets after losses, similar to the Martingale, Labouchere, and Fibonacci strategies, though it is less aggressive. As an experienced bettor who has already tried numerous betting strategies, I will provide you with all the crucial information on how this strategy works. 

What Is The D’Alembert System?

This betting system is attributed to Jean-Baptiste le Rond D’Alembert, an 18th-century French mathematician. Similar to Martingale, it is a negative progression method involving increasing bets after losses and decreasing them after wins. However, compared to Martingale, the D’Alembert betting system increases stakes at a slower pace, reducing the risk of excessively high bets. 

Based on my own experience, I believe that this strategy is a more cautious alternative to aggressive betting systems. While this offers an advantage by reducing the risk of substantial losses, it also means that losses are recuperated at a slower pace. Consequently, after I tried it in practice, I discovered that the likelihood of experiencing losses is slightly higher, but any losses incurred tend to be less severe during streaks of bad luck.

The D’Alembert system in sports betting is based on the gambler’s fallacy, also known as the Monte Carlo fallacy. This is the mistaken belief that the likelihood of an outcome alters when, in reality, it remains constant. D’Alembert was misled by this fallacy, asserting that the probability of a coin landing on heads increased with each occurrence of tails. However, this notion is incorrect, as the probability remains unchanged regardless of prior outcomes.

How The D’Alembert Strategy Works In Sports Betting

This system for betting operates on the principle of increasing bets after losses and decreasing them after wins. Using the example of a coin toss, if a bettor loses a bet on heads, they are instructed to stick with heads and raise the bet size. In the D’Alembert betting system, the progression of bet increases is more gradual than in other systems, which helps mitigate the risk of extremely high stakes. 

After putting it to a test, I found that this method is particularly effective for markets with two potential outcomes, such as Over/Under, Both Teams to Score, or Asian Handicaps, and can be adapted to various sports. While this provides certain benefits like decreased chances of significant losses, it also means that recovering from losses takes longer. 

For example, if your initial bet of $1 is unsuccessful, you will need to raise your stake to $2 in the subsequent round. If this bet also fails, you will then wager $3, and so forth. However, following a winning round, you will observe that you’ve not only recouped previous losses but also generated a small profit. So, this strategy can lead to short-term wins, helping to generate profits or cover losses from poor runs.

How To Build a D’Alembert Strategy

Drawing from my practical experience, I will guide you through the process of building the D’Alembert betting strategy step by step. First of all, this system is based on units, where the initial wager amount serves as the base unit. For example, you decide to bet on a football match between Dallas Cowboys and Washington Commanders, with odds of -110 and +120, respectively, an initial wager of $10, and a total bankroll of $100. To keep it simple, we’ll consider that all the next wagers will be with the same odds.

If your base unit bet at odds of -110 succeeds, you gain a clear profit of $9.09, leaving your balance at $109.09. Upon another successful wager, you increase to an $18.18 net profit, maintaining the same base unit stake. This elevates your balance to $118.27. Should the third bet end with a loss, you suffer a $10 reduction in your bankroll, bringing it down to $108.27. Subsequently, you add a base unit and bet $20 for the next round.

If you face another consecutive loss, your bankroll decreases by $20, leaving your net profit at -$1.82 and your balance at $98.45. At this point, you have made four wagers totaling $50, with a 50% win ratio (two wins and two losses) at odds of -110. Your net gains consist of $18.18 from the first and the second bets, while losses from the third and fourth bets amount to $20.

If you choose to continue with the D’Alembert betting progression, you will add one base unit to the last $20 bet. With a $24 win, you’ll gain a net profit of $4.45, boosting your bankroll to $102.90. Achieving a 60% win rate will earn you $4.45, making the strategy profitable in the short run.

Advantages And Disadvantages

If you are hesitating whether to utilize the D’Alembert betting system for making your own bets, I compiled a list of benefits and drawbacks.


  • A low-risk betting strategy, suitable especially for beginners in online gambling.
  • Straightforward implementation without intricate calculations required.
  • Modest profits in quite a short period of time.
  • Universality in diverse sports disciplines.


  • Relatively low profits which may not be advantageous for professional bettors.
  • No guarantee of constant profits.
  • Slow recovery from a prolonged losing streak.

Comparing The D’Alembert System To Other Strategies

As a sports betting expert, I should point out that the D’Alembert betting strategy is not a single variation accessible to bettors. There are also other alternatives that have their own mechanics and offer their benefits. Below, I will provide you with an insight into the nuances of two other alternative approaches to the standard system.  

Multi D’Alembert Progression

This variant allows flexibility in adjusting your stake amount throughout the progression. It means that progressions can either increase or decrease, each leading to different overall results. Depending on the specific game and bets involved, these progressions can bring positive or negative results.

Reverse D’Alembert

In this variant, you simply reverse the standard D’Alembert system. Instead of increasing bets after losses and decreasing them after wins, this system involves increasing bets after wins and decreasing them after losses. 

Is it Worth Using this Strategy?

Through my profound expertise in sports betting, I would say that the effectiveness of the D’Alembert betting system in securing profits is debatable. While it might work well in the short term, especially when facing more losses than wins, it has a flaw. Relying on a specific sequence of outcomes makes it vulnerable during extended losing streaks, potentially resulting in significant financial losses.

My research showed that there are a few adjustments that can be made to enhance the appeal of the D’Alembert system in sports betting. For instance, increasing the stakes by two or more units after each bet can potentially improve profitability, especially when outcomes alternate between wins and losses frequently. However, this approach carries the risk of larger losses during extended losing streaks.

Another modification involves setting a maximum stake level, after which the stakes are reset to the base level. For instance, you might opt never to exceed five times your base stake. This can help minimize losses during prolonged losing streaks but may also reduce the likelihood of recovering losses.


Summing up, I find the D’Alembert betting system to be a nice choice for bettors who prioritize a low-risk approach to wagering. While it may not yield substantial gains in the short term, its steady and consistent nature makes it quite appealing for some gamblers. The system’s simplicity, versatility across various sports disciplines, and modest risk of losses make it particularly suitable for beginners in the world of betting. However, like with any other betting strategy, I strongly recommend being cautious while implementing this approach and avoiding the temptation of increasing your stakes rapidly in an attempt to recover losses.
