Another popular roulette system is the d’Alembert system. This system assumes that after a win, a player is less likely to win again. So after a win, you subtract a chip from your bet. The d’Alembert system also assumes that you’ll be less likely to lose after a losing spin, so in that case, you add a chip to your bet. The flaw in this thinking is that the roulette wheel has no memory, and each spin is an independent trial with exactly the same odds of a win or loss as the previous spin.

The d’Alembert Roulette System springs from the progression named after the great mathematician and physician, Jean Baptiste le Rond d’Alambert who lived and worked in France in the 18th century. The d’Alembert roulette system is based on the following rule: each time a player loses, one unit should be added, so that in total the sum of units will be one unit more and each time when a player wins the value of a bet should be one unit lessened.

The d’Alembert roulette system is thoroughly advised to be applied to even odds. It’s obvious that you can have either red or black numbers, either odd or even numbers, though you shouldn’t forget about a zero slot in European roulette and both a zero and a double zero slots in American roulette, for the zero slots influence losses greatly. Beyond doubt the probability of a player’s win is likely to increase when there are no zero(s). By the way, if you intend to have 100 spins a day, that’s why making your mind to put your stakes on red numbers for fifty spins at the beginning, and the rest fifty spins you want be red bets, you can’t be sure that it’ll be red numbers that will win at first and black numbers then. However, you can shift your bets from red to black colour boxes, hopefully fortune will shift ball slots together with you, so that you win as much as possible. For 100 spins we suggest 100 wins, though the d’Alembert roulette system is as risky as all the other betting strategies, including the Fibonacci roulette system. Nevertheless it can be red numbers or black numbers that will be preferred in a row, give it a try, you can like the game, as a roulette game is thought to be one of the easiest games played in casinos.
The D’Alembert system is usually applied to even bets (such as black or red). Very simply, depending on whether a bet wins or loses, you’ll either decrease or increase your next stake accordingly.

For example, if you bet £2 on red and your bet loses, you’d double your next bet to £4 red. If this bet wins, you’d reduce your next bet by 50%, back down to £2. As you can see, by increasing your stake when your bet loses, you aim to recover your loss and make profit with the following bet(s).

The genius aspect of the D’Alembert is the reduction in stakes following a win – it may sound crazy to seemingly take a step backwards, but in fact you’re protecting your win. Following a win, your probability of a consecutive win decreases – therefore reducing your bets makes sense until your probability of winning again increases!
The D’Alembert system can work like clockwork, and many people swear by its consistency – however, be aware that you can still lose using this system. As with all roulette strategies, you always run the risk of hitting a spell of losing bets – therefore it’s vital to have a stake limit where you stop betting, before you blow a hole in your bank! If you’re unfortunate enough to have a bad run, either quit your session or start again with your minimum stake.

The d’Alembert roulette system is fairly simple to use, because there are no difficult series that are impossible to remember. In conclusion it should be noted that there is the anti-d’Alambert roulette system, as well as there is the anti-Martingale roulette system.
