Roulette is a game that is highly stacked in favor of the house when compared to other casino games. It is mostly a game of chance, and depending upon whether it is a “single-zero” or “double-zero” wheel, the house edge is generally 2.7 percent or 5.26 percent, respectively.

This being said, it’s best to come to the wheel with guarded expectations. People often make money at this on an individual basis, to be sure, but the overall odds are in favor of the house in the long run. For every big loser at Roulette, chances are that there is an even bigger winner somewhere appeasing the gods of chance.

Betting Systems
There are three basic betting systems that have been known to generate some success, though they each have their own downfalls.

• Martingale

This system involves simply doubling the amount bet each time you lose. It sounds scary at first, but there is some merit in using it. How do you do it? If you bet \$10 on even and lose, drop \$20 on even. If it loses, go for \$40. If you win, you will have a profit of the original bet, which was \$10 in this example.
The problem arises when you lose consecutively enough to the point which you cannot double your previous loss due to the table limit, and the profit is gone.

• Grand Martingale

This is like the Martingale method on steroids; in addition to doubling your bet when you lose, you add the original bet to it. If you win, your profit becomes twice the original bet, and using the above example, your profit would be \$20.
The problem here is that reaching the table limit happens more quickly, meaning it takes less consecutive losses before your profit is lost to the house.

• Cancellation

This can be a bit confusing, but you are less likely to blow your entire bankroll as quickly as the Martingale systems do.
You start with a series of numbers, for example: {\$2,\$3,\$4,\$5} or {\$1,\$1,\$1}. We will consider the first set in the following example.
Your first bet would be the first and last number in the series added together, in this case \$2+\$5, or \$7.
If you win, cross off both these numbers, and play again, using the \$4 and \$3 that are remaining as your next starting point.
If you lost the first round, you would then place the losing bet amount, \$7, to the end of the list, which would now be {\$2,\$3,\$4,\$5,\$7}. Your next bet would be the sum of the first and last numbers in this series, or \$9.
This method continues until you either exhaust your bankroll, or all of the numbers are crossed off. If you get to cross off all of your numbers, you have made a profit.
