D’Alembert Betting System in Roulette – How & When To Use It

The D'Alembert betting system is one of the simplest and most popular strategies used in gambling, including roulette. It bears most similarities to the Martingale strategy, but it’s far less aggressive, making it common among beginners and casual roulette players.

Below, you can learn how the D’Alembert betting system works and decide whether it fits your gambling style. 

What Is the D’Alembert System — The Gambler’s Fallacy

The D’Alembert betting system is named after Jean-Baptiste le Rond D’Alembert, an 18th-century French mathematician. During the research, D’Alembert concluded that external and inertial forces acting on bodies form an equilibrium system. This conclusion became known as the D’Alembert Principle and laid the foundation for Newton’s Second Law.

According to him, the chances of a coin landing on heads increases if it has already landed on tails multiple times in a row.

In roulette, the D’Alembert equilibrium law stemmed from the idea that future outcomes could balance the unlikely results in the past. For instance, if a ball lands on black several times in a row, it’s bound to fall into the red pocket, becoming the more likely outcome. 

However, the premise itself is flawed as the odds remain the same, regardless of the previous outcomes. This concept is also known as the gambler’s fallacy, and many casino players have fallen for it, chasing losses and going bust. 

Does the D’Alembert System Work?

D'Alembert Strategy RouletteThe D’Alembert is a negative progression system standard in even-money roulette wagers. It harnesses the idea that players should have roughly the same amount of winning and losing bets.

So, instead of decreasing the stake after losing, a player increases it. Likewise, a player should reduce the stake after winning a wager.

It’s a straightforward betting system with only several rules. Here’s a short guide on the steps you should take:

  1. Decide on the base unit — Before starting the game, decide on the base staking unit. The amount could be as high or as low as you’d like, but a rule of thumb is that it shouldn’t exceed 5% of your entire roulette bankroll.
  2. Start with one unit — Start the roulette session with the precise unit and return to it every time you begin a new game.
  3. Increase the stakes after a loss — If you lose a wager, you’ll increase the stake by one unit. So, if your initial stake was $5, the next one should be $10, and so on.
  4. Decrease the stake if you win — After a winning bet, you’ll reduce the stake by one unit. You won’t have to change the bet amount if you’ve won with the base unit.

Implementing the D’Alembert betting system is simple, but the question is — does it work?

Many players have tried and tested this strategy, and one thing is sure — the D’Alembert system can help you win in the short term, even if you lose a series of wagers.

However, for that to happen, you need a particular sequence of results. That’s where we see the main flaw, as any series is possible, and entering a lengthy losing streak can be quite costly.

The main weakness of the D’Alembert system is that nothing can guarantee if or when the losing streak will end. Therefore, while it can be advantageous for a short gambling session, it can also decimate your entire bankroll without giving you a chance to recoup the losses.

Pros and Cons of the D’Alembert System

D’Alembert System vs. Other Roulette Betting Systems

Over the years, roulette experts have created many strategies to try and boost their winning odds. Today, players can choose between several tried-and-tested betting systems such as:

Each focuses on different game elements and carries specific rules that apply to various playing styles. While most are aggressive and require higher stakes, the D’Alembert system is the most efficient in low-stakes roulette games

For instance, the Martingale system requires you to double your stakes after winning, which can be quite risky. On the other hand, the Fibonacci strategy, which relies on the famous string of numbers, requires players to join the last two bets and place them in a new round. 

Both strategies imply increasing your stake after winning, while the D’Alembert offers some balance between raising and reducing the stakes. Therefore, the D’Alembert could help you minimize the losses without hitting the table limit or going bust.

Conclusion

Although everyone knows that roulette strategies can’t guarantee wins, they can give more winning opportunities and help preserve your bankroll. The same goes for the D’Alembert system. It’s a simple strategy to implement and somewhat safer than other betting systems, as the pace at which you increase your stakes is slower.

However, it’s unlikely you’ll cover your previous losses with one winning bet, so it’s crucial to understand the risks before moving on with the strategy.
