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. But despite the simple mathematics that governs most roulette games, there is no such thing as a perfect roulette system. Reason number one is that you cannot alter the house advantage of 5.26%. The second reason being that no roulette system is able to determine the pecise outcome of every spin.
Roulette System: Probability Theory
Some authors base their roulette systems on probability. The system that works in poker games is not likely to work in roulette. Probability in roulette is based on evaluating all possible outcomes via the process of elimination.
So for instance, you make a Straight Up bet on 35. The first spin lands on thirty one. In the spin that follows, it does not mean that now you have thirty seven odds remaining since you subtracted thirty one from thirty possible results. 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. In its simplest form this type of roulette system tells you to double your bet after each loss until such a time that you 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 roulette system based on the Martingale system, you double up the bet to $10, $20, and then $40, which total up to $75 worth of losses. 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 good, right? 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 is the problem with luck. It comes and it goes but to wager all you’ve got on that one time win is a complete waste.
