D’Alembert Roulette System

The subject of betting systems (such as the D’Alembert roulette system) is controversial. On the one hand, you have pushy salesmen telling you they have the key to winning at roulette every single time. On the other hand, there’s a school of thought that says there is no way to invent a winning betting system for any casino game.

Before you make your mind up about the D’Alembert Roulette System, read on to learn how it works, how it was designed, and what we think about it.

How To Use The System

This roulette system is extremely simple. To follow the D’Alembert roulette system, you start by making a wager of moderate size. This bet should be worth at least a few dollars more than the table limit, but a bit larger might be better. Ideally this should be an even-money roulette wager like red/black or even/odd.

If this starting bet is won, collect your winnings and repost the same bet worth $1 less. If your wager loses, however, you need to sustain the loss and repost a bet worth $1 more than the original bet. As you play on, you need to treat each and every wager like this. Stick with the same exact bet; each win means you need to bet less, and each win means you need to bet more.

The Theory Behind The D’Alembert Roulette System

Basically, the D’Alembert roulette system relies upon the fact that, over time, there will be normal distribution of all possible outcomes. To try to take advantage of this information, the D’Alembert uses the spins you’ve already seen to predict what outcomes will (or will not) appear soon.

When you make your bet smaller after a win, it is because you believe that it is unlikely that the same bet will win immediately again. When you increase the size of your wager after a loss, it represents the belief that it is less likely that the same bet will lose two times in a row.

Does This System Work?

The D’Alembert roulette system makes a great deal of sense, but if it seems too good to be true, that’s because it is. The driving force behind the D’Alembert system is one of the most common gambling misconceptions: The Gambler’s Fallacy. This is the belief that past spins directly affect future spins, but in reality this is not true.

After a roulette spin results in a 14, the ball is removed and the wheel continues spinning. By the time the dealer gets around to starting the next round, everything is completely random. The following spin is completely independent from the first example, and another 14 is just as likely to appear as ever.
