D’Alembert System – Application with example
The D’Alambert system is a betting system with negative progression, where you bet more if you lose and less if you win.
The D’Alembert system is also called “Progression D’Alembert” or “Pyramid 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 times 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 winning immediately after a loss over a long period of time. The same applies vice versa. That is, a win is most likely to be followed by a loss.
Luckily, the amusement of casino games destroys most mathematical principles based on the long duration (or infinity) of things. So is the law of balance. Nevertheless, many players use the D’Alembert game system for Roulette, Baccarat and Blackjack (both 17 and 4, as well as various Blackjack variants).
Application – how is the D’Alembert system played?
D’Alembert is a system with negative progression.
You bet one unit higher on loss or one unit lower on win.
The D’Alembert Progression System is quite easy to use. This system only bets on simple odds, in Roulette this would be red/black, even/odd or 1-18/19-36. After each loss the player raises his bet by one unit. Conversely, the player reduces his bet by one unit after each win.
Let’s take a look at the system using a concrete example: If the player starts with €10 (€10 = one unit) and loses, he must bet €20 next time. If he then loses again, he must bet €30 the next time and so on. However, if he wins the €30 bet, he reduces the next bet by one unit to €20.
Other than with other betting systems, there are no cycles in Progression D’Alembert that bring the player back to the initial €10 bet. Each bet is either one unit higher or lower than the previous one, depending on whether a game was won or lost.
Advantages of the D’Alembert System
The advantages of D’Alembert Progression are obvious: It is easy to remember and use. The rule is easy to understand and can be implemented immediately in every game. However, if you are confronted with a series of losses, you will quickly notice that the stakes are skyrocketing. This makes the system quite risky, although less risky than the popular Martingale system (where the stakes are doubled after every loss).
In comparison to the Martingale system, which is based on a similar principle (although here the stakes are doubled after every 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 there is a chance to make up for the losses before the table limits or your own budget set limits for the system.
Disadvantages of the D’Alembert System
Was the stakes do not increase as rapidly with the flat progression of the D’Alembert System as, for example, with the Martingale System, but often not a single profit is enough to make up for the losses again. It may be correct mathematically that in the long run losses can be balanced again, but with the play in the genuine life comes sometimes differently. And then – at least in roulette – there is zero or double zero: The house advantage of the bank. And also the D’Alembert system cannot beat that. The chances stand thus also with this system for the player always a breath worse.
