D’Alembert Roulette Strategy
The D'Alembert Roulette Strategy is a betting system much like the classic Martingale method. It's super straightforward and based on a progressive betting pattern. However, unlike the steep progression available in Martingale or Paroli betting systems, D'Alembert's is much flatter. The concept here is to add one unit to your bet after a loss and remove one unit after a win.
Judging by the name, a good guess is that it has French origins. But what you may not be able to predict is that this system has been around since the 1700s when French mathematician Jean-le-Rond D'Alembert invented it. It's relatively unpopular, but it’s the safest out of the lot. Let's see how this method can boost your winning chances at the Roulette table.
Applying the D'Alembert Roulette Strategy
The main idea is identical to the Martingale system, increase bets on a loss and decrease bets on a win. However, the changes are less aggressive, since it only involves a unit difference.
Here's an illustration;
- If a player stakes $5 and loses, the next bet will be $5 + $1 = $6
- If the following $6 stake loses, the next bet will be $7
- If the following $7 stake loses, the next bet will be $8
- If the following $8 wins, the next bet will be $8 - $1 = $7
The system works best with high odds bets. So, once again, like the Martingale method, even money bets like Red/Black, Even/Odd, and High/Low are the go-to, as they have winning chances of close to 50%.
There's little preparation required, and players can begin applying this method soon after setting their base bet amount. You can use it on any Roulette variant, and all top casinos have got a host of exciting Roulette options for you to put your skills to practice.
Advantages of Using This Method
The D’Alembert system is an excellent option for beginners and players on a limited bankroll. You're only adding a single unit with each loss, so there's a relatively low financial risk.
It's also quite interesting to know that you'll end up with a profit even when you lose as much as you win. Extending the previous illustration, let's say;
- You bet $5 and lose
- You bet $6 and lose
- You bet $7 and lose
- You bet $8 and win
- You bet $7 and win
- You bet $6 and win
After three losses and three wins, you end up with a profit of ( – 5 – 6 – 7 + 8 + 7 + 6) $3.
Besides, with this unit addition rule, you'll most likely never have to worry about hitting the table limit.
Drawbacks to This Method
The flat progression may be safe and easy, but it limits the win potential. It doesn't hold out in the long term, either. The chances of getting an equal number of wins and losses become less unlikely over time, and you'll definitely be at a disadvantage thanks to the house edge.
The D'Alembert system also fails at covering losses in the short term when a bad streak occurs. You would need an equally good streak to wiggle your way to a profit, and the chances of that happening are even bleaker.
Tips for Using the D’Alembert Roulette Strategy
- The recommended amount for the base bet is a small amount relative to your casino budget. 2% of your bankroll is a good place to start.
- Try out variations of the D'Alembert method like the adjusted progression and contre D’Alembert.
- Use this Roulette strategy for free at any of our recommended top online casinos before playing for real money.
Variations of the D'Alembert Method
Gambling enthusiasts have tried out several alternate versions of the D'Alembert Roulette strategy, and some of them have stuck over time.
D'Alembert with Adjusted Progression
This variant allows a bit of freehand for you to make your own modifications to the bet progression. For example, instead of adjusting by one unit, you can adjust by two or more units. This will increase your profit margin on successful bets. However, it also means you can lose more.
Another idea is to reset your stake to your base bet once you reach a specific amount. For instance, you can stop increasing your stake once you reach 4x your base bet. This helps curb excessive losses.
Contre D'Alembert is simply the reverse version of the standard rules. So, you'll be increasing your bet after a win and decreasing it after a loss. Here an equal number of wins and losses will most likely result in a loss. On the bright side, it requires a much smaller bankroll, and it's easier to recover from a bad streak with this method.
