Reverse D’Alembert- Roulette Strategy

Reverse D’Alembert Betting Strategy

The Reverse D'Alembert Roulette strategy is based on modifying the roulette bets in the opposite way as you would if you were using the D'Alembert strategy. The rules of the D'Alembert strategy state that the bet should increase by one unit after a loss and decrease by one unit after a win. In the reverse D'Alembert strategy the bets are made in the opposite way. So when there is a loss the bet should decrease by one unit, until the base bet is reached and when there is a win the bet should increase by one unit until the limit of the table, or the player has been reached.

How the Reverse D'Alembert Betting System Works

Before starting to play, the amount of the base bet must be established. To do this, firstly the total size of the bankroll must be established and then a betting unit that is around 2% but no more than 5% should be used. It is also important to consider the bet limit of the table that

will be used. You should make your bets on the options that have as close to a 50/50 chance of winning so either Red or Black, Odd or Even, 1 to 18 or 19 to 36.

It is easy to understand that the reverse D'Alembert strategy, in the case of a series of consecutive losing rolls, will decrease the amount of the player's balance less than if the D'Alembert system or Martingale system were being used. The rules of the reverse D'Alembert strategy mean that a lower bankroll can be used at the start of the game.

Reverse D´Alembert Betting System Examples

Here is an example of a game situation that has a series of unfortunate spins one after the other. The roulette table has a lower limit of 10 and an upper limit of 750. The scenario is that the player has made a base bet of 10 and bet on red but the ball has landed on black numbers 7 times in a row.

We will compare the differences between the bets if the player uses the Reverse D´Alembert, D´Alembert or Martingale Strategies:

1 10 10 10 Lose
2 10 20 20 Lose
3 10 30 40 Lose
4 10 40 80 Lose
5 10 50 160 Lose
6 10 60 320 Lose
7 10 70 640 Lose
TOTAL 70 280 1270  

If the player was using the Reverse D´Alembert then their next bet would be for 10 and they would have bet a total of 80. Whereas if the D´Alembert was used then the player would make a new bet of 80 and would have bet a total of 360. In order to make the next bet using the Martingale strategy the player would need 1,280, which is obviously higher than the table limit of 750, and they would have bet a total of 2,550.

Obviously the results will be different if the outcome of where the ball lands is a mixture of losses and wins:

1 10 10 10 Lose
2 10 20 20 Lose
3 10 30 40 Win
4 20 20 10 Lose
5 10 30 20 Win
6 20 20 10 Win
7 30 10 10 Lose
TOTAL 110 140 120  
PROFIT -30 10 0  

However, in the same way as in the other anti-progressive systems, in the D'Alembert inverse strategy, with a few wins in a row the bet grows by one bet amount. Therefore, it is important that the player decides before sitting at the table what their loss limit will be and stick to it. This also applies to winning amounts, it is advisable to have a win limit, for example 30% and once this is reached they should leave the table.
