Ever since roulette became a popular gambling pastime in the 18th century, players have been trying to find the way to beat the house. One of the betting systems that developed in this quest for a perfect roulette strategy is D’Alembert – named after a famous mathematician who developed it.
The D’Alembert roulette betting system relies upon a simple rule: every time you win, decrease the size of your wager; every time you lose, increase it. Of course, this needs to be done in accordance with several other rules in order to get the system to work.
Before you start playing roulette using the D’Alembert betting system, you need to do a small amount of planning. First, see what the table’s minimum bet is, and set your starting bet to a medium size. You need to be able to successively lower the starting bet without going below the table minimum, as well as to increase the bet without spending your budget too fast. Then, decide how much you are going to decrease or increase your bet each time you win or lose, respectively. The size of decrease/increase needs to stay the same throughout the game.
Another thing that shouldn’t change during the game is your bet (e.g. Black, Even, 1 to 18). The D’Alembert betting system will only work if you keep betting on the same outcome. Note that you should only place bets that give you nearly 50% chance of winning, such as Red/Black, Even/Odd or 1 to 18/19 to 36.
The D’Alembert betting system in roulette works best in long gambling sessions, and only carries the risk of small to moderate losses when the player experiences a long losing streak. Altogether, D’Alembert is a well-balanced, negative progressive system and its simplicity makes it a good strategy for beginner roulette players.
