How does the D’Alembert system work?

This betting system is used if you want to make an even-money bet on a roulette table.

Experts have suggested that this system can be used on other wagers apart from roulette games.

The theory is beliefs that the disparity between your wins and losses will be roughly the same.

To make it clearer let’s use the red and black options a roulette table.

This theory expects that red would like to appear almost the number of times during a gaming session as black.

This system is straight to the point and very easy to understand.

This forms part of why it is popular among gamblers.

For easier understanding, we have specified the basic steps with examples.


  • Always determine what your base betting unit will be. You can choose the lowest amount on the betting line.
  • For instance, if the betting line comprises the following amounts $2, $3, $4, $5, and so on, it will be advisable to start with $2.
  • Also, another way to choose your base bet is to use 2 or 5 percent of your bankroll.


  • Don’t bet more than one base staking unit for the first bet.
  • For example, if you choose $2, stick to this amount until the end of the betting cycle.


  • If you lose a bet, increase your stake in the next cycle by one unit.
  • For instance, if your base bet is $2, and you lost the bet, the next should increase to $4.
  • Then if you lose, your next stake should be $6.


  • This is the opposite of step 3.
  • When you win any bet, your stake should reduce by on staking unit.
  • For instance, if you stake $6 and win, the next wager should be $4.

The whole system is very clear and simple. If you win the same number of bets that you lost, you definitely get some profit.

It is simple because you staked more when lost and stake less when you won.

It sounds very interesting but does it really work?

Let’s find out.

Is the D’Alembert system an effect system?

It is obvious that the D’Alembert system can help a gambler win some cash but some doubts may arise. Does it work always?

Certainly, this theory is just like any other betting system is likely to fail at some point. The major advantage of this strategy is that it will help you mitigate your loses and increase your chances of winning.

For example, if you stake $5 and lose, then stake $10 in the next cycle, you will recover, your previous loss.

The challenge with this system is when the stake starts increasing – especially when you lose more than two cycles.

  • It enables players to recover their losses quickly
  • This system gives you an edge over the house

History of the D’Alembert system

Let’s digress a little. D’Alembert system is named after Jean-Baptiste le Rond d’Alembert a French mathematician.

He has developed this theory after he had played several times and lost. One of D’Alembert’s mentors was Isaac Newton.

Jean like other Players relied on the popular gambler’s fallacy. After it didn’t work, then the D’Alembert system was formulated.

His betting principle became popular and so many gamblers make use of this theory. Casinos and software developers also embraced this system to ensure fairness.


D’Alembert system appears to be flawless but just like most betting strategies, it has some flaws.

Assuming you have more than 6 straight losses, it means that you will be losing 6 times your base bet. This is the major downside of this betting system.

Come to think of it, with this system, you can recover all your losses with just one win. How?

If you stake $5 and lose, then stake $10 in the next cycle and win, you will recover your initial $5 and some profits.

Some may say this system encourages chasing loses but it is not entirely so. The aim is to recover all your losses as quickly as possible and maintain a lead against the house.

You can give this betting system a try when you are playing for fun. If you use it while you are playing for real money, the possibility of losing more money is higher.

However, you have a 50 percent chance of winning some money using this betting strategy.
