D’alembert Roulette Strategy

The D’alembert progression-based Roulette strategy takes its name from the 18th-century French Roulette theorist Jean le Rond d’Alembert. The method, similar to the Martingale strategy, whereby you increase your bet after a loss, is still risky but not as damaging on your bankroll if you hit a long run of losing spins. Let’s take a more detailed look at how this strategy plays out and determine if it works and if it’s worth using.

How Does The D’alembert Roulette Strategy Work?

Implementing the D’Alembert Roulette system is incredibly easy and consists of placing a single wager on an even money bet. All even money bets are red or black, 1-18 or 19-36, odd or even. Although these are not 50/50 bets mathematically, they are as close as you can get when playing European Roulette, as there is only one zero on the wheel. This means you actually have a 48.65% chance of winning.

Starting the strategy requires an even money bet, so I will bet €5 on red. If this bet is successful, I will profit €5 and start the process again by betting another €5 on red. As with the Martingale Roulette system, this strategy becomes a progression-based method once you hit a losing spin. However, the D’alembert slightly differs by requiring you to bet another unit every time you lose rather than doubling up your bet like you would in the Martingale.

So I’ve bet €5 on red and lost, as I started with a €5 unit; my second bet is now €10). If this loses, my next bet will be €15, increasing by 1 unit for every losing spin. The interesting part of this strategy is when you hit a winning spin again, let’s say I win on the €15 spin. Rather than dropping down to the original stake of €5 like you would with the Martingale, you drop down 1 unit so that the next bet would be €10.

You keep playing with this strategy, either increasing by a bet unit for a losing spin or decreasing by a unit for a winning spin. When this eventually balances out, and you get back to your original bet of €5 a spin, for every winning spin you achieved in that series, you will have made €5 profit for each one, leaving you in profit for your overall session.

Whilst there are plenty of plus points about the D’Alembert strategy, it also has its pitfalls. The steady incline of bets by one unit per time when losing will mean that it is very unlikely you will fall foul of reaching the table limit like you could when using the Martingale system. However, unlike the Martingale, if you have a terrible run using the D’Alembert method, you can find yourself having to get a lot of successful spins to get your money back.

Overall this is a good strategy if you have an endless amount of time and can wait for the good and bad runs to even themselves out, so you end up with a profit. The reality, however, is that sessions are often short, and you have either some good luck or bad, so if you do manage to get some success with this system and get yourself into profit, then be sure to cash it out and try again another day.
