The D’Alembert is a system that advises to raise your bet after a win and lower it on a win. This strategy can be used for any casino game, but in this guide, we will be looking at how to use it in roulette. Unlike the Martingale strategy, with the D’Alembert roulette system, you only increase or decrease your bet by a small amount.
When you consider using the strategy, instead use it on a bet that has a 50% chance of winning. These bets are even/odd, red/black, and 1-18/19-36 bets. Find out more on how this roulette system below.
The strategy uses a negative progression pattern. You can use the D’Alembert roulette system as per below:
Wager on an even chance.
When you lose, you will increase your bet by 1 unit.
If you win, you will reduce your bet by 1 unit.
You will repeat this pattern until you hit your loss limit or make a profit.
Once you have made a profit, you will collect your winning and choose to stop or start over.
For a more precise understanding, we will look at how this applies to a roulette game. Firstly, you will choose which roulette game to play.
You will start the game by placing a bet of $5 on black.
The wheel is spun, and the ball lands in the 29 black pockets. Since you bet on black, you win and get a profit of $5. You will keep your profit and place a unit bet on black.
The wheel will spin again, and this time it lands on seven red. You lose your bet by $5 and add a unit to your stake, making a bet $10 black.
When then the ball lands on black 24 you win and make a $10 profit. You will then reduce your next bet by a unit, making it $5.
