Before I begin, I recommend reading my review on the roulette system. It is by far the best on the web at the moment.
For a game that relies on the whims of Lady Luck and Dame Fortune, roulette has inspired quite a lot of people to invent roulette systems that are “guaranteed” to work. Yet apart from simple mathematical equations that rule roulette games, there is no perfect roulette system. Reason number one is that you cannot alter the house advantage of 5.26%. Reason number two is that no roulette system can accurately determine the outcome of each spin.
Roulette System: Probability Theory
Some authors base their roulette systems on probability. Now, while this kind of roulette system works perfectly in poker games, in roulette, it’s not likely. Probability in a roulette system works by determining all the possible outcomes through the process of elimination.
So for instance, you make a Straight Up bet on 35. The first spin shows you 31. In the next spin, it doesn’t mean that you only have 37 odds left since you subtracted 31 from your 38 possible outcomes. It’s quite possible that the next spin will result in the same number, the number 31.
This is why a roulette system that is based on pure probability will not work. In theory, perhaps this roulette system works but in practice, it’s not likely and you’ll end up losing more than you intend.
Roulette System: Martingale
Several roulette systems are variations of the martingale system, which is basically a “double up until you win” approach to gambling. This system tells you to essentially double your wager after each loss that you incur until you eventually encounter a winning spin. With such a system, your final bet will make up for any losses in previous bets, making you a nice little profit.
For example, you bet $5 and lose the first spin. Using the Martingale system, you continue to multiply your bet by two to $10, $20, and then $40, which total losses in the amount of $75. Your wager is multiplied by two from $40 to $80 on the 5th spin, now you are risking $155. However, you get lucky and win, earning you a profit of $5. Sounds appealing, correct? Wrong.
This roulette system only works if you have an infinite amount of money and an infinite amount of free time. Sure, there is no doubt that eventually, you will win. That’s the thing with luck. It comes and it goes but to wager all you’ve got on that one time win is a complete waste.
