The same as Martingale, the D’Alambert roulette system is based on a negative progression and can be used in all even chance bets, such as odd/even, red/black, or 1-18/19-36. It was named after the French mathematician Jean-Baptiste le Rond d’Alembert, who has gone down in history as a victim of his own philosophy.
Even though it’s not known how much this cost him, but he fell for the gambler’s fallacy – misbelief that the probability of an outcome has changed when it’s actually remained the same. So keep that in mind while reading this article.
How to use D‘Alambert System
It‘s not a secret that the D‘Alambert system is one of the most common and popular betting systems out there. The main reason for that – it’s really not complicated and easy to learn. You already know that it is a negative progression system and there are 4 basic steps to master it:
- Stick to the base unit. The first thing you need to do is set a base unit you’ll be using. A safe shot would be to go with 2% of your bankroll. Never change base unit midgame.
- Always start with one base unit.
- Go up after a loss. After every loss, you should add one base unit to your next bet. Let’s say your base unit is $2 and you lost your first bet, then the next one should be $2 + one base unit ($2). If you lose again, you should repeat the same – $4 + one base unit ($2).
- Go down after a win. Just like after losing, your bet should be alternated by one base unit. The difference is that after winning you should go down. If you won with $6 bet, your next one should be $6 – one base unit ($2).
This betting system doesn’t require you to count or memorize anything and in theory, you should come out with a profit due to winning bets being at higher stakes than losing bets.
Advantages of D’Alambert System
As mentioned before, the D’Alambert system is not complicated so there is almost no chance of a human error. Also, you can play with a very low bankroll and minimize your risk of losing a significant amount of money. It features a relatively low risk and can be a great way to steadily grow profit.
Disadvantages of D’Alambert System
Since this is a low risk strategy, you can’t expect a lot of winnings. Basically, you should win as many bets as you lose, and only record profit because of winning bets being bigger.
Obviously, the biggest risk and disadvantage is going on a ridiculously long losing streak that can burn your bankroll.
Extra tip: set a target for a profit and stop-loss margin and stick to it. Discipline is always a good idea.
