D'Alembert Roulette System
Inspired by the theories of a mathematician dating back over 200 years, from whom it also takes its name, the D'Alembert roulette system is one of the gaming strategies used by many players in the world, especially to minimize losses and prolong the length of your gaming budget. In fact, the D'Alembert roulette system is not designed to favor large instant wins, however, it can help you make a profit in the long run.
Just like the martingale system, this is also applied to outside bets such as odd or even, high or low and red or black. The progression that makes up the system is quite simple: the player adds one unit to their bet after each losing spin, while removing one unit after each winning spin. To better understand how it works, let's take an example. Let's assume we are using an initial bet of € 1 on red. After the first spin, the bet was lost. For this reason, on the next spin we continue to bet on red, but this time € 2. In the event that the spin is still a loser, we will have to bet € 3 on red on the third spin. In case of a win, to continue the progression it is necessary to return to wager 2 €, removing one unit after the win.
As you can see, the system is slightly more intricate than the martingale and does not allow you to profit after a single winning spin. Taking the example above, if the player decided to stop playing after the win on the third spin he would not actually get any profit since the total cost of € 6 for the three spins is exactly the same as the win. However, if the fourth spin turns out to be a winner, the player would make a net profit of € 4.
This means that the D'Alembert roulette system requires a longer playing time to allow you to take a real advantage. The player must always keep an eye on his spending and stop the system when he reaches a satisfactory net profit, given by the sum of several winning spins. The D'Alembert system is not perfect. The strategy is based on winning and losing streaks, trying to make the most of a win and minimizing the risk of losing large parts of your budget. This is why after each winning spin the player must remove one unit from his bet in order to protect himself from a possible subsequent losing spin which could jeopardize the net profit.
