Tips for Understanding the D’Alembert Roulette System

There are so many gambling strategies, and some of them may even work if you implement them properly. In general, the betting systems are invented to be a guide for those who want to use some strategy in order to win.

But, it doesn’t mean they work for everyone. We can say that even the luckiest among the gamers are not using commercial strategies. But, they are a nice point to start and build your own unique approach to gambling.

One of the most popular methods is the strategy of Jean-Baptiste le Rond d’Alembert, a famous French mathematician. He invented a system similar to the Martingale, but less progressive and more likely to recover than previous losses. Most of these betting systems can be used on every online casino, including, but you have to make sure you understand them pretty well.

So, today we will focus a little more on the D’Alembert roulette system, and we will see how you can use it in your everyday gambling routines.

How does this roulette system work?


As you can imagine, D’Alembert is the easiest to implement when playing roulette. In general, the method uses basic principles like Martingale, but it is not as aggressive. When applying this method, you need to increase the bet every time you lose and decrease it when you win. Although it sounds like something you can not imagine doing, you must know that this system, at times, really works.

The theory is that when you have an equal number of wins and losses, you are not at zero, but you have made a certain profit.

To begin with, you have to choose how much you start with. In online casinos, you do this with virtual chips that you later convert into winnings. If you are a beginner, you can play with a small bet, so you can see how this system works. When you realize, you can relax more and “untie your arms” and take more risks.

Gambling is an activity in which if you do not take risks, you do not gain anything, but you do not lose. And if you take the risk, then the situation is “all or nothing”. In roulette you do not have many possible outcomes, so sometimes it is perfectly okay to gamble. However, to apply D’Alembert successfully, you must also know the rules of the method.

And here are the basic rules you need to know before you implement the strategy:

  1. Choose the basic amount with which you will start the game. Most often, players choose a value of about 1% of the total budget available to them. This will help you to have control over how much money you can afford to spend.
  2. Next, you need to choose your bet, for example, whether it will be red or black, even or odd, or it will be from 1-18 or from 19 to 36.
  3. If you win, lower your stakes. For example, if you bet $ 10, this time you bet $ 9. But if you lose, add another dollar.
  4. It is very important to stay consistent when it comes to this variable unit, which you add or subtract from your wager.

Example of how D’Alembert Roulette strategy works


Knowing the rules, we need to give you an example of how you should apply them. At the beginning of the game, you decide what will be your bet in roulette, and then what will be the unit that you will give and take. In this example, we will take that you invest $ 20 and subtract or add one dollar each, and play a total of 10 times.

If you lose the first time, you add another dollar to the next hand. So, you have $ 21 and 9 more attempts. When you lose for the second time, you add another dollar and you have $ 22 and 8 attempts.

If you win this time, it means you are left with $ 21 (plus the amount you won) and 7 attempts. If you win again, you have $ 20 (plus the amount you won) and 6 attempts. Let’s say you lose in the next attempt. You now have $ 21 and 5 more attempts.

If you lose this time you need to add another dollar, i.e. 22 dollars, and 4 more attempts. In the next two wins, you lose two dollars, and you add one to the loss, but even if you win again, you come to the conclusion that you have not lost anything at all.

However, keep in mind that in this example we have described an ideal and non-dynamic situation and that in reality, it would not be so ideal. But this way you at least get an idea of ​​how this system works.

Advantages and disadvantages of this system


Like everyone else, the D’Alembert system has its pros and cons. For example, the great advantage is that it is easy to learn how this system works. You can also play at tables with limits, but also have constant control over what you do.

The downside, as you may have guessed, is the minimal profit and the ability to go home without losing almost anything ideally. However, the system is not very applicable in more dynamic games, where it is necessary to follow other players in their bets. If you have a long losing streak, then you are getting more and more into your bankroll and you may feel like you have nothing to lose.


This is an article that describes the basic rules of the D’Alembert strategy, and an easy example of how to understand it. As we said, the example shows an ideal situation but gives a clear image of what you have to do, in order to apply the system properly in your gambling habits.

You can revise other games, and see if you can apply this system there. But, we can say that it’s best to stick to roulette because that’s why this strategy exists in general.
