D'Alembert System application with example

The D'Alambert system is a betting system with a negative progression, in which you bet more when you lose and less when you win.

The D'Alembert system is also called "Progression D'Alembert" or "Pyramids game system". It was named after Jean-Baptiste le Rond D'Alembert , one of the most important mathematicians and physicists of the 18th century. Not only did he have it with mathematics, he also worked as a philosopher in the age of Enlightenment.

The strategy named after D'Alembert is a loss progression and is based on the law of equilibrium. The law says that a player has a very high chance of an immediately following win over a long period of time after a loss has occurred. The same also applies in reverse. That is, after a win, there is a high probability that a loss will follow.

Unfortunately, the entertaining nature of casino games nullifies most of the mathematical principles based on the long duration (or infinity) of things. So is the law of compensation. Nevertheless, many players use the D'Alembert game system for roulette, Baccarat and blackjack (both 17 and 4, as well as in various blackjack variants).

Application - how is the D'Alembert system played?

D'Alembert is a system with negative progression.
You bet one unit higher in the event of a loss or one unit lower in the event of a win.

In the system of progression D'Alembert is quite easy to apply. With this system, you only bet on simple chances, in roulette this would be red /black, even / odd or 1-18/19-36. After each loss, the player increases his bet by one unit. Conversely, the player reduces his bet by one unit after each win.

Let's look at the system on a concrete example: if the player starts with â'10 (â'10 = one unit) and loses, the next time he has to bet â'20. If he then loses again, he has to bet â'30 the next time, etc. But if he wins the â'30 bet, he reduces the next bet by one unit to â'20.

Unlike other betting systems, there are no cycles in the Progression D'Alembert that bring the player back to the initial â'10 bet. Each bet is either one unit higher or lower than the one before, depending on whether a game was won or lost.

Round	Use	Result	Profit (net)
1	CA$10	Loss	- ABOUT$10
2	CA$20	Loss	- ABOUT$30
3	CA$30	Loss	- ABOUT$60
4	CA$40	Loss	- CA$10 0
5	CA$50	Profit	- ABOUT$50
6	CA$40	Profit	- ABOUT$10
7	CA$30	Loss	- ABOUT$40
8	CA$40	Profit	CA$0
9	CA$30	Profit	CA$30

Advantages of the D'Alembert System	Disadvantages of the D'Alembert system
The advantages of Progression D'Alembert are obvious: it is easy to remember and apply. You understand the rule quickly and can implement it immediately in every game. However, anyone who is confronted with a series of losses will quickly notice that the stakes are skyrocketing. This makes the system quite risky, although less risky than the popular Martingale system (where the bet is doubled after each loss).	Compared to Martingale System based on a similar principle (but here the stakes are doubled after each loss), the D'Alembert is less risky. Because it uses a flatter progression than the Martingale system. This means that the stakes increase more slowly and thus there is a chance to compensate for the losses before the table limits or your own budget set limits to the system.

The D'Alembert of Blackjack and slot machines

The D'Alembert system is most often played in roulette, but this strategy can also be used in blackjack and slot machines.

If you want to use the D'Alembert system in blackjack, it works just like in roulette: after each loss, the player increases his bet by one unit. Conversely, the player reduces his bet by one unit after each win.

And the D'Alembert system is just as easy to use for online slots: after each loss, increase the bet by one unit, after each win, decrease by one unit.

Variant: Inverted D'Alembert System

Sometimes a Contra-D'Alembert system is also used, which reverses the strategy. That is, after a win, the bet is increased, and after a loss, it is reduced. So it's a profit progression. The advantage over the original D'Alembert variant: even less capital has to be used, because those who suffer losses over a longer period of time do not always have to invest more money in the game and try to compensate for them.

The Contra D'Alembert system is therefore not quite as risky as the standard D'Alembert system. But even this system is not a guarantee of safe or long-term profits in the casino. First of all, with this system it is advisable to think about how long you want to use them in the game. There are players who – as with the Martingale system - set themselves, for example, 4 or 5 wins, after which they no longer increase their bet, but start again at the original bet and go through the progression from the beginning.

D'Alembert system: conclusion

The D'Alembert system is often used in online casinos and gaming houses, especially by players with a more cautious disposition. It's a system that beginners can use as a guide, but in the long run the D'Alembert system isn't there to leave the casino with huge winnings. It certainly doesn't hurt to have a look at the system, if you want to take an even lower risk and always have your budget in mind, you should try the Contra D'Alembert system. As with all betting systems, the same applies to D'Alembert and Contra D'Alembert: The advantage still lies with the bank – if it were different, the system would be banned very quickly.

It is best to try the D'Alambert strategy right away and find out if it suits you.
