DÁlembert system text with roulette wheel and ball in background.

The D’Alembert betting system is a negative progression system, meaning that players increase their bets after a loss and decrease them after a win. It is named after French mathematician Jean le Rond d’Alembert, who believed that small, incremental increases in the size of bets would eventually result in a win. The D’Alembert system is often used in casino games such as roulette and blackjack, but it can also be applied to other forms of gambling, such as sports betting.

History of the D’Alembert Method

The D’Alembert method was developed by Jean le Rond d’Alembert in the 18th century. He was a French mathematician, philosopher, and scientist who is best known for his work in the fields of calculus and probability. D’Alembert believed that if a player increased their bets by a small amount after a loss and decreased them by the same amount after a win, they would eventually come out ahead. He argued that this system would allow players to take advantage of the “law of averages,” which states that over time, the outcome of a game will tend to balance out.

How the D’Alembert Method Works

The D’Alembert method is a relatively simple betting system that involves making incremental changes to the size of your bets based on the outcome of previous rounds. Here’s how it works:

Start by choosing a base bet amount and a betting unit. The base bet is the amount you will wager on each round, and the betting unit is the amount you will increase or decrease your bet by after each round.

Begin playing the game and make your base bet on the first round.

If you win on the first round, reduce your bet by the betting unit on the next round. For example, if your base bet is R10 and your betting unit is R5, your bet would decrease to R5 on the second round.

If you lose on the first round, increase your bet by the betting unit on the next round. Using the same example as above, your bet would increase to R15 on the second round.

Continue this pattern of increasing your bet after a loss and decreasing it after a win until you reach your desired level of profit or stop playing.

How To Use This Method

To use the D’Alembert method, follow these steps:

Choose a base bet amount and a betting unit. These should be based on your personal bankroll and risk tolerance. It’s generally a good idea to start with a low base bet and a small betting unit to minimise your risk.

  1. Begin playing the game and make your base bet on the first round.
  2. If you win on the first round, decrease your bet by the betting unit on the next round.
  3. If you lose on the first round, increase your bet by the betting unit on the next round.
  4. Continue this pattern of increasing your bet after a loss and decreasing it after a win until you reach your desired level of profit or stop playing.

Variants of the System

There are several variants of the D’Alembert betting system that players may choose to use. These include:

Multi D’Alembert Progression

The Multi D’Alembert progression is a variant of the D’Alembert system that involves increasing or decreasing the size of bets by a multiple of the betting unit rather than just the betting unit itself. For example, if the betting unit is R5 and the progression is set to 2, the size of the bet would increase or decrease by R10 after each round. This variant of the D’Alembert system can be more risky than the traditional version, as it involves larger swings in the size of bets.

The Reverse D’Alembert

The Reverse D’Alembert is a variant of the D’Alembert betting system that involves increasing the size of bets after a win and decreasing them after a loss. This is the opposite of the traditional D’Alembert system, which increases bets after a loss and decreases them after a win. Some players believe that the Reverse D’Alembert system may be more effective than the traditional version, as it takes advantage of winning streaks rather than trying to balance out losses.
