The Reverse D’Alembert System is a positive progression strategy that helps you capitalize on winning streaks when playing casino games such as roulette, blackjack, and baccarat.
It is applicable to 50/50 bets, such as a blackjack hand or a red/black side bet on roulette. This article explains the principles of The Reverse D’Alembert System, its pros and cons, and some popular alternatives.
What is the Reverse D’Alembert System?
The D’Alembert System is a negative strategy that requires you to increase the size of your bet by one unit after each loss, and decrease it by one unit following a win. The Reverse D’Alembert System is the opposite – you increase your bet amount after a win, and you decrease it after a loss.
You must start by choosing a base unit. This can be 5% of your bankroll, as an example. You then place your first bet for one unit. If that bet wins, you bet two units the next time. If that bet wins, your next wager will be for three units. If you lose, go back down to two units.
Reverse D’Alembert System Example
Imagine your base unit is $10. You place a bet on red at a roulette wheel. If it loses, you bet $10 again. Keep going until you win.
After winning, increase the size of your bet to $20. If you win again, go up to $30. If that bet wins, stake $40 on the next spin of the roulette wheel.
If you lose, go back down to $30 for the next spin. Keep going up by $10 after a win and down by $10 after a loss.
Reverse D’Alembert System Pros and Cons
The D’Alembert System is all about chasing losses, and it does not capitalize upon winning streaks. The Reverse D’Alembert System turns it on its head, and it does work well when you are on a winning run.
For example, if you start out by betting $10 and you win seven in a row, you will be up $280. If you were following the D’Alembert System, you would only be up $70, as you do not increase the size of your stake after a win.
The Reverse D’Alembert is a very easy system to understand, more so than alternative positive progression systems, so it is popular. It does not require a large bankroll, and it is reasonably low-risk.
However, it does not chase losses, so you can end up down by several units without increasing the size of your bet amount. It is also more cautious than some alternative methods.

Reverse D’Alembert System Alternatives
If you are looking for a more aggressive positive progression strategy, you could try the Reverse Martingale, which requires you to double the size of your stake after a win. If were to start at $10 and win seven in a row, you would be up $1,270.
However, if you lost your eighth bet, you would be down $10 overall. If you won seven in a row and then lost the eighth bet using the Reverse D’Alembert, you would still be up $200. Alternative positive progression strategies include the 1-3-2-6 Betting System, the Paroli System and the Oscar’s Grind.
If you would prefer to chase down losses, while bidding to secure a number of small wins, negative progression strategies such as the Martingale System, the Fibonacci System, the D’Alembert System and the Labouchere System might appeal.
They do not capitalize upon winning streaks, but they ensure that a big win can’t wipe out previous losses.
