# D’Alambert Roulette Strategy

## Roulette Tactics and Strategies in General

Roulette is a game invented by a mathematician: Blaise Pascal. His intentions were not creating a casino game, although the mathematical formulas developed by Pascal still determine your winning odds (and the advantage of the casino). For this reason, in order to have an idea of roulette tactics and strategies, you first need to learn these mathematical principles and possibilities. We will give you general information about roulette tactics first, then we will see how they work together to make the most use of these tactics. Let’s start from the beginning: There are 37 or 38 numbers on the roulette wheel. The difference is determined by the rule system used by the game: American roulette has an extra “00” section on the wheel, so the total number increases to 38. “0” and “00” are the casino’s digits. So if the ball falls to these sections, the casino is considered to have won. For this reason, the first thing we need to know is to play the European version of this game. There is only one “0” section on the wheel, therefore, this version offers a higher chance of winning. Stay away from the American roulette, the casino edge is too high because of the extra digit.

## Which Roulette Bets Are the Best?

As is known, there is not a single bet option in the roulette game. You can bet on a certain number, a range of numbers, certain colors and whether the result will be odd or even. For each betting option, your odds of winning vary. As you can imagine, betting on a single number offers the lowest winning possibility but the highest payout. The betting options that are most likely to win are color and odd-even bets. When you play these bets, your odds of winning are always 47.37%. Why not 50%? Because the “0” number on the roulette wheel, as mentioned above, belongs to the casino and always gives an edge of %2.63 to them.

This information is important because almost all roulette strategies are based on these four betting options. Other bets offer very low odds that cannot be calculated. In other words, they depend entirely on luck. For these four bets, even without using a tactic, your chances of winning are already high enough: 47.37%. With a few simple strategies, you can pull this number up even further. Since the payout rates of these bets are low, you won’t become a rich person with a few spins, but you will not go bankrupt too! You’ll see that there are dozens of roulette tactics on the Internet, but very few of them really work. The D’Alambert roulette strategy is probably the most known strategy. It is also the easiest tactic and can be applied even if you do not have any mathematical knowledge.

## What is the D’Alambert Strategy and How to Use It?

This strategy, developed by a French mathematician of the same name, uses a pyramid shape. The greatest feature of the system is that you can keep your losses to a minimum. It doesn’t help you get very high profits, but it prevents you from suffering excessive losses. Implementing the system is very simple: Let’s imagine you start playing with 1 unit (bet). If you win, you will add 1 more and play the next bet as 2 units. When you lose, you will remove 1 unit from your previous bet. So if you play with 8 units for example and you lose, your next bet will be only 7 units. But there is another very important rule to follow: You will only place bets for the 4 options we explained above: Color, Odd/even, 1 to 18, and 19 to 36.

D’Alambert system will allow you to control your losses. It is a progression system, which allows you have full control over your bets and budget. Here is a real-world example:

- We start by playing, let’s say, 100 EUR.
- When we win, our next bet will be 200 EUR.
- If we lose, our next bet should be 100 EUR again.
- The raise limit should be the limit of the table we are playing at.
- 100 EUR is our minimum bet. Even if we keep losing, our next bet should always be this number, until we start winning.

The biggest benefit of the D’Alembert roulette strategy is that it allows you to increase your bet amount more slowly. It is not an aggressive system like Martingale or Labouchere. You are less likely to lose large amounts by using this method. For example, if you lose 7 times in a row and follow the Labouchere method, you will lose 123 units in total. However, using the D’Alembert method will limit your losses to 28 units under the same conditions.

### Disadvantages of the D’Alembert System

The D’Alembert system assumes that the roulette wheel has a “memory” and sooner or later, you are bound to win. This is called the “gambler’s fallacy”. We like to think that if the ball landed on black, the possibility of landing on red becomes higher for the next spin.

Unfortunately, this is not true. There is no guarantee that the ball will land on a certain section and the odds do not raise with each spin. In fact, that 47.37% possibility is a “fixed” number, and although it is a high number, this gives no guarantees of a definite result. With every spin of the wheel, all possibilities are calculated from the beginning, possibilities do not increase nor ” accumulate”. You can see this yourself by playing heads or tails: Getting heads for 10 times does not guarantee that the next one will be a tail.

For this reason, using the D’Alembert system will not give you a profit guarantee, but you will be able to control your losses. In this respect, the D’Alembert strategy is a more suitable system for beginners. Its implementation is simple and does not contain complicated rules. Set yourself an upper limit, and even if you win, do not exceed this limit. This way, you can use D’Alembert’s system most efficiently.
