Although it is said that the outcome in a game of roulette is almost completely dependent on someone’s luck, there are some systems that have evolved over the years. It is widely believed that these systems allow gamblers to get past the house advantage that every casino builds into the game.

**The Labouchere System**

The Labouchere System, also called the Cancellation System is considered a perfect system for the game of roulette. If you want to follow this system you need to take a piece of paper and write down the number of units of betting you are trying to win along with the number sequence that can help you reach this goal. So, to win 15 units you need to have the sequence 1-2-3-4-5. You now add the first and the last number. i.e. 1 and 5 and bet the amount, i.e. 6. If you win you cancel 1 and 5 and now take the sequence 2-3-4. Add 2 and 4 and bet another 6. If you lose you add a new number to the sequence, i.e. 6. Now add 1 and 6, i.e. 7 and bet this amount.

**The Martingale System**

For the Martingale System to work you need to bet on even. You bet an initial figure and double it if you lose. If you win you bet the same initial figure. So, if your first bet was $10 and you are increasing by $10 for every subsequent spin, you bet $20 in the second spin if you lose and $10 if you win. The fundamental of this system is that your final will wipe out all the losses you have incurred so far. The drawback is that you may go broke if your run of losses goes on.

**The d’Alembert System**

The d’Alembert System works opposite to the notion that once you win you keep on winning. It assumes that your chances of winning are less when you have just won and the chances of winning are more when you have just lost. So, if you bet $5 and win you should bet $4 in the next spin. On the other hand if you bet $5 and lose you should bet $6 in the next spin.

These are the three most common systems used in roulette. Many people have benefitted from these systems and many haven’t. You need to try them out and see if they work. If they indeed work then you may as well continue with them.
