D’Alembert Roulette Strategy

The D’Alembert system is one of the easiest roulette strategies available to players, and is commonly used to make small profits in short bursts.

You’re unlikely to see massive wins from this strategy, however, with some patience, you can see the smaller wins develop and grow without the risk of wagering a lot of money.

How To Use The D’Alembert System

The D’Alembert system is a negative progression strategy, so you’ll be betting more after a loss. Here’s how you use the system:

  • Choose an initial wagering unit (this can be any amount you like). Make this an affordable amount as you’ll only be betting more than this later on.
  • After a loss, increase your bet by one unit.
  • After a win, lower your bet by one unit (going only as low as your original bet).

The idea behind this strategy is that when you’re on a winning streak you can make safe bets and keep your losses low. When you’re losing, placing a larger amount will quickly see your balance bounce straight back up, allowing you to control your losses.

Here’s an example of how the D’Alembert system works:

  • Place 1 unit and lose (-1).
  • Place 2 units and lose (-3).
  • Place 3 units and win (0).
  • Place 2 units and win (+2).
  • Place 1 unit and lose (+1).

As you can see, even after suffering more losses than wins, you’re still able to end with a profit. At the same time, because there was a winning streak, having to lower the wager meant that when the loss eventually came, it didn’t have much of an impact on the total sum.


  • No large losses, meaning you can manage your money.
  • Plays the numbers in your favour, allowing you to see a profit even if you’ve lost more than you’ve won.
  • Simple to understand and implement.


  • Only works in short bursts, don’t use this strategy for hours on end.
  • You’ll only see larger wins over a long time.
  • A losing streak will ruin your bank balance.
