Play The D'Alembert System- a Betting Strategy

The D'Alembert system is named after Jean le Rond d'Alembert (1717 – 1783) who was a French  mathematician.

This system, also called montant et demontant (from the French, climbing and descending), is sometimes called a pyramid system.

It is based on the mathematical equilibrium theory devised D'Alembert in the 18th century.

Like the Martingale, this system is often applied to the even-money roulette bets (such as red/black), but can be played across a number of online casino games.

It´s a progression, and a very simple one at that. After a loss, one unit is added to the next bet, and after a win, one unit is subtracted from the next bet.

So say your starting bet was 5. Lose, and you bet 6 on the next bet. Lose again and you bet 7. Win and you bet 6, win again and you are back down to 5, and so on.

This system plays to the often held belief that you are less likely to win after a win and less likely to lose after a loss. This belief is often known as the Gambler´s Fallacy, because statiscally, this is not the case. The roulette wheel, craps table, blackjack shoe and slots machine are inanimate objects. They do not have a memory! Your chances of winning after a win are exactly the same as your chances of losing after a win.

Basically, what the French mathematician was trying to demonstrate, is that if you take a number of events together, and the results skew one way, then the system will automatically tilt back to the equilibrium. So if you are monitoring 100 spins of the wheel, for example, and you see R,R,R,R,R,R,R,R (8 reds in a row), the system will veer back so that over the course of a session you will see 50 red and 50 black (or near to it).

But you have to be careful here! Predicting the total number of reds in 100 spins is one thing, but in roulette you are betting on the next spin and the next spin only! You are not betting on the result of the next 100 spins. And in the case of 1 spin, your odds of spinning a black are exactly the same as your odds of spinning a red, whether you have had 8 reds in a row previously or not.

Of course, this doesn´t necessarily mean that you can´t give the D´Alembert a test. Just remember that given the nature of this system, it can drag on so make sure (as you should always do) that ave you have set firm profit and stop loss limits.
