There are many roulette systems out there that exist. Among all of them, the martingale system has been around since the 18th century and is acknowledged as the most popular to date. Martingale was initially made to refer to a category of betting strategies where a gambler gets to win his bet if a head comes up after tossing a coin and loses if it a tail shows up instead. This strategy will dictate that a player should double the bet for every loss so he could recover what he lost from the previous bet and win an equal profit with his original bet.
Application of the System
The martingale system is easy to follow and one can easily catch up on this idea real quick. Players may start going for progressives which is the main basis of the system when betting in roulette games. One should bet on even money wagers only such as betting on black or red, high or low, odd or even. If you lose your bet, double the bet amount on your next try. If the next one is another lose, double the amount again on your next bet such that when you win, you get all your previous losses back. In eight consecutive bets where you would double your previous bets, you would need a bankroll of at least $ 255 when starting with $ 1 bet. From bets 1-8, what you would need to shell out each time are $ 1, $ 2, $ 4, $ 8, $ 16, $ 32, $ 64 and $ 128.
Many beginners may start wondering about the logic of betting $ 255 only to win back $ 1 of bet. The answer is that, in most instances, the probability of losing 9 bets in a row is very minimal and you are winning the entire bets you placed instead of winning just $ 1.
Probabilities for Roulette Variations
Several casinos may offer either American or European roulette and between the two, the European version is a better option for the Martingale system. This version approximately provides an equal chance than American roulette. It is also 20% safer to play. The probability of winning an even money bet in the European version is 48.6% while it is less at 47.3% for American roulette. The probability of losing nine consecutive bets is higher with the American version at 0.31% while it is set at 0.25% for European version. With the European version, there is a probability of losing once in 400 spins when compared to 1 in 320 spins for the American version. On the flipside, the probability of losing in as many spins is quite high. This means that the Martingale system will prove to be profitable even with the American version of roulette.
Consider, too, the limits set for betting. The chance of using this Martingale system can be limited. This is all the more true if you are tight on your bankroll and are scared of losing that much. Think first if this is the system that's best suited for you.
