About Roulette Game Martingale System

About Roulette Game Martingale System. The Martingale is the best-known roulette betting system. It varies greatly. The principle is following: when you win, you pocket your bet. But when you lose, you double the size of your previous bet. If you win that will guarantee you get back your previous loss and one more unit. And so on.
The Martingale System works great only in case you are not limited in your bankroll and betting.
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 are less likely to lose after a losing spin, so in that case, you add a chip to your bet. The fact that the roulette wheel has no memory and each spin is an independent trial with exactly the same odds of a win or loss is the previous spin is a weak point of the system.
