Bonus Roulette Roulette Systems

Bonus Roulette Roulette Systems. One of the most popular betting systems in roulette is the Martingale. There are a great number of variations of it. The principle is following: when you win, you pocket your bet. If you lose, you should double your previous bet. By doing this in case you win, 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. The system is based on the assumption that after a win you are 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.
