D'Alembert Progressions
D'Alembert: We increase the next bet with one unit if we lose and we decrease one unit if we win. The aim of this system is to find a balance between the two chances. The D’Alembert System works by the assumption that over a given period of time, there will be an equal number of wins and losses. This system has two big benefits over some other systems. The first is that your bets don’t increase as fast as some systems, and this lets you stop the session at any time for a small to medium loss. The second benefit is that if you find your bankroll to be positive during the game, you can stop the system at any time and accept a win. When you play using the D’Alembert system you will only win if a balance of wins and losses has been achieved starting with a series of negative spins. This system works only if there is a balance between winning and loosing bets. This system is not as potentially dangerous as the Martingale System but you must always be prepared for some very large losses.
Here you can find and example:
| Number of bet | Result on odds of 2.00 or more | BankRoll (100) |
| 1 | Lost | 99 |
| 2 | Lost | 97 |
| 3 | Win | 100 |
| 2 | Lost | 98 |
| 3 | Lost | 95 |
| 4 | Lost | 91 |
| 5 | Win | 94 |
| 4 | Lost | 90 |
| 5 | Win | 95 |
| 4 | Win | 99 |
| 3 | Win | 102 |
D'Alembert reverse: The D'Alembert system can be played reversed too. Instead to increase when you lose, you can decrease of one unit and the same if you win you increase your stake of one unit
Good Luck with your bet !
