How does the d'Alembert work?
The d'Alembert gambling system is a negative progression system. In other words, you raise the bet when you lose and lower it when you win.
Invented by French mathematician Jean le Rond d'Alembert, it is based on 'the equilibrium of nature' which means it works when you get an even number of wins and losses for the same bet.

d'Alembert Gambling System
Stable and simple
The d'Alembert gambling system has similarities with the Fibonacci, in that it's reasonably stable for alternating results, but unlike the Fibonacci system, even a mild consecutive losing streak results in a loss.
It has the advantage of being simple. The bets can be tracked as you go - there's no need to write anything down.
The stretched d'Alembert
Many roulette strategists swear by the d'Alembert system or variations such as the 'stretched' d'Alembert - where the bets only change after a number of winning or losing bets eg 1,1,1,2,2,2,3,3,3,2,2,2 etc.
Small, consistent wins
Like all negative progression gambling systems, a long streak of losing bets can cause moderate losses.
Our gambling strategy tells you to limit losses by deciding in advance how much you're willing to lose. The last test suggests going for no more than 5 or 6 consecutive losses.
If you're a medium-risk gambler, the d'Alembert system will suit your style. It gives you the chance to make consistent wins without the threat of massive losses.
Try it yourself - risk-free
If you're unsure where the Evens chance bets lie in our featured games, you may prefer to try the d'alembert system for free on the 50/50 bets (Odd/Even, Red/Black, 1-18, 19-36) in roulette. To facilitate this, we're pleased to provide the following link:

Sequence
The sequence of bets in a losing streak is therefore:
1
2
3
4
5
etc
The sequence of bets for 3 losses and 3 wins would be:
1
2
3
4
3
2
Cancel losses with wins
The advantage of this system is that it doesn't chase losses, it gets them back slowly, always certain that in the long run the results will be 50/50.
