How the D’Alembert Roulette System Works
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.
