Roulette became popular in Western Europe in the 18th century and from then people tried to create a system that could beat the roulette wheel.
Jean le Rond D’Alembert was a mathematician who invented this roulette system based on his own idea that for a long period of time, all the numbers in the wheel will come up equal. On his theory, if you make a bet and win, you have a big chance of losing on the next spin, and the other way around. Having this in mind, D’Alembert had found out that if you bet less after you win and bet more after you lose, so if you win you reduce your bet into 1 and if you lose you increase it by 1.
If you win, then you reduce your next bet with $1 and bet it on the same color. You have a 50% chance of winning in the roulette game if you use this system. To use this, you need to double the amount of the bet you lose in the previous round. In that way you can earn some profit if you win. This system assumes that the probability of two losses in a row is a lot smaller than a single loss.
By using the D’Alembert Roulette strategy, you are taking a big risk of losing a few times in a row. So the wise move is not to start with a high amount of bet and learn about the betting limit of the casino. There is a small possibility that you will always win in a row but losing is for sure going to happen.
If you are not familiar with this strategy, you might want to consider testing it in online casinos. You can play for free using virtual money and see if this system works for you. You don’t only get to know the best way to make profit but also teaching yourself to become responsible and careful.
