The D’Alembert Strategy

If you are new to the roulette table or a casual player who is after the entertain and a few wins, the D’Alembert Strategy should serve as the perfect fit. It bears some similarities with the popular Martingale strategy, but this one is designed as a low-risk version and should work well that can double one’s stake back, like an odd or even and red or black.

Things You Should Know About the D’Alembert Strategy

This strategy actually shares some similarities and counter-acts the limits of the Martingale Strategy. As a strategy, this was developed and popularized by Jean Le Rond D’Alembert, a French physician and mathematician. Born during the 18th century, D’Alembert has this belief that all outcomes with a 50-50 chance of winning will always balance each other out.

He explained that Outcome A will have a higher chance of winning if Outcome B had occurred many times in a row. For example, if the ‘red’ bet has been playing out for quite some time, it only follows that the chance of hitting a ‘black’ on the next round increases. In short, in the D’Alembert principle, outcomes are expected to balance each other out, resulting in both outcomes displayed almost the same number of times. Of course, this idea of D’Alembert has some problems knowing that each spin of the wheel is always at random, even though a certain number or event has occurred 20 or 50 times in a row.

Here’s How You Can Play the D’Alembert Betting Strategy

This strategy comes with basic rules and perfect when playing bet alternatives that can double your wager, like an even or odd and a red or black. First, you will need to identify first the base stake that you want to adopt. In every loss that you will encounter on the roulette table, you will need to increase your wager by a unit, but you will reduce it by the same number in case you win the round.

Of course, the exception to this rule is if you win the first time, and you will not be able to lower your base wager. Here, a betting unit is equal to the base stake, which means that throughout your play you will need to increase and decrease your wager depending on the results of the wager.

Say for example you started with a base wager worth €2, and you place this on a ‘red’ and you lost when the ball dropped. If this is the case, you need to increase your wager by one unit, boosting the wager to €4 on the next play. And if you lose again on the next round, you will need to increase the wager by a unit, pushing it to €16. But if you managed to earn a win, the D’Alembert Strategy calls for a reduction of your next wager by one unit.
