# D’Alembert system

## The basis of the D’Alembert system

The D’Alembert system, as mentioned, allows you to play roulette with more confidence and less risk. As in the Fibonacci system, in the D’Alembert system you also play on the (as good as) 50/50 possibilities that roulette offers. These are the red/black, even/odd and 1-18 or 19/36 options.

Depending on your betting budget, each time you lose in the round you are going to bet an extra unit the next time. With a one euro bet, this is the easiest way to display it; 1 (loss), 2 (loss), 3 (loss), 4 (gain). But it could also be that you play with units of 5 euros and then you add 5 euros per losing round to your bet. After each win you go back one step in your bet.

### The 50/50 system in practice

As with any other roulette strategy, or roulette in general, your goal with the D’Alembert system is, of course, to win as much as possible. If you systematically opt for 50/50 options, then it is first of all important that you stick to your original choice; are you willing to bet seven or eight rounds in a row on one color, on odd or on the first 18 numbers?

On the other hand, it is important that you have enough budget to implement the D’Alembert system in practice. So you should not play with units of 5 euros, while your total budget is only 30. You then need to win within six rounds, which is rather risky, since roulette is a general game of chance.

### An example

The D’Alembert system has been around for a long time, yet few people choose this roulette system. Too bad, because if you don’t like to lose money during an evening out, then this system is extremely suitable. You don’t have to take any unnecessary risks and with a little bit of luck, you’ll have a nice accumulated profit at the end of the evening. To give an example of the D’Alembert system, let’s assume a 5 euro table, because that is the minimum standard in Holland Casino. You’ve brought a budget of 50 euros with you to the casino and with that you can play up to 10 rounds.

In order to maximize your chances of winning, choose a table where an odd number has been hit five times in a row and naturally choose an “even” number to bet on. Not only do you feel more likely to win, but it’s also statistically a good option to bet on. It looks like this;

• First bet: 5 euros on even (loss)
• Second bet: 10 euros on even (loss)
• Third bet: 15 euros on even (win)
• Fourth bet: 10 euro bet (loss)
• Fifth bet: 15 euros bet (loss)
• Sixth bet: 20 euros (win)
• Seventh bet: 15 euros (win)
• Eighth bet: 10 euros (win)

Playing Roulette with a system

### The outcome of the D’Alembert system

The above example is obviously a rosy view of how the D’Alembert system should work for you. Your third bet is turned into a profit and thus your first two bets have been made good. Therefore you go back one step and the fourth and fifth bets result in a loss of 25 euros. The sixth bet, however, provides another \$20 profit and your seventh and eighth bets also provide \$25 profit. At the end of the day, you’re left with 20 euros in pure profit. Congratulations, you have correctly implemented the D’Alembert system and won!

Roulette is for many people one of the most fun and frequently played casino games. The game with a total of 37 numbers is familiar to everyone and not difficult to understand. Many people who play roulette in Holland Casino use some tactics or a system, but in practice they don’t know whether this can actually lead to winning. Roulette, however, is an ideal game to apply systems to, in order to increase your chances of winning. It is a risk-averse system, but in many cases it also allows you to win less money.
