D’Alembert Roulette Strategy

The D’Alembert roulette system is also known as the Montant Et Demontant, meaning upwards and downwards. Since this is more like a pyramid combination, it is basically based on a mathematical balanced hypothesis that was conceived by a French mathematician of the same name.

This specific strategy has some of the same similarities that the Martingale system has, applying to the even money outside bets only and to be profitable is with an even distribution of outcome. The players who want to keep the amount of their bets and losses to a minimum favor this method.

The simpleness to the progression of the betting is as follows: One unit is added to the next bet after each loss and one unit is deducted from the next bet after each win. If the player is starting with an initial bet of 9 units, a loss would then raise the next bet to 10 units. If this is preceded by a win then the next wager should be 19 units. So if there is another win then it would lower the next bet to 8 units.

This betting system relies on the players deception meaning that the player is more hopeful to lose following a win, and more hopeful to win following a loss.

This strategy is a common one, but some players find it confusing at times.
