The D’Alembert roulette system is a simple progression system. After each win, you subtract a unit and after a loss, you add a unit. You can start at one unit or sometimes 5 to 10 times the minimum. In our example, we will start at 5 units.
| Bet Number | Units bet | Result | Running Total |
|---|---|---|---|
| 1 | 5 | loss | -5 |
| 2 | 6 | win | +1 |
| 3 | 5 | loss | -4 |
| 4 | 6 | win | +2 |
| 5 | 5 | win | +7 |
| 6 | 4 | lose | +3 |
The D’Alembert, like most betting systems, uses the even money bets (red/ black/ odd/ even/ high/ low) to cut down on variance. In the example above, there are 3 wins and 3 losses. When the wins and losses are even, the gains are just the number of wins. Due to the 0 in roulette, you can expect to win 18 times and lose 19 times out of 37 spins.
Basically, as with most progressive systems, they work in the short term. A long streak will bankrupt you though. Its no where near as aggressive as the
Code for roulette Xtreme, it’s in the built-in system files too.
