Rules and Strategy

Roulette Strategy

Online roulette is above all a game of chance. It’s impossible to predict with 100% certainty, 100% of the time, which number the ball will land on. Each roll is independent of the last which means in statistical terms it’s not impossible for the ball to land on the same number or colour multiple times in a row.

During your first few games of online roulette, it’s important to use a reliable strategy. This allows you to be more comfortable with the game before you start taking risks. If you bet large amounts during your first few games, you run the risk of eating into your bankroll very quickly and it might discourage you from playing in the future. It’s equally important to be in a good frame of mind when you play. Staying focused enables you to avoid making any big mistakes which could prove very costly in the long run.

Your best bet in European and American Roulette is the "outside" one (red, black, even, odd ...), which gives you a 48.64% and 46.37% chance of winning respectively. For example, if you place $1 on the "outsides" during each turn in European Roulette, after 37 rounds you'll end up with $36.00. This is because you will fall at least once on the 0 which is the casino's advantage.

If you think it's possible to beat the roulette wheel on a regular basis, with a betting system like the "Martingale" for example, think again. The only potential winner in the long run in that scenario is the casino, given its advantage by way of the zero (and the double zero in American Roulette). However, that's not to say that during a hot streak you couldn't win over and over with this system.

Before you start playing, it is recommended that you read the rules of roulette. They are not as complicated as they seem, and once you have read and understood all the subtleties of playing, roulette becomes much more fun. You can practice for free on our site, which is a very good way to grasp the nuances of the game. It is also good way to remind yourself that ultimately what's most important is for you to have fun!

The Probabilities in Roulette

We will explain the probabilities of the different possible combinations in roulette. It is easy to calculate the chances and it’s equally important to understand them when you make a decision before the ball is launched.

American Roulette Statistics

American Roulette has 36 numbers as well as a zero and double zero. So, there are 38 possible slots into which the ball can land. If you bet on a single number, you have a 1 in 38 chance to win. Here are the probabilities for all possible combinations in the table below:

Red1 to 146.37%
Black1 to 146.37%
Even1 to 146.37%
Odd1 to 146.37%
1-181 to 146.37%
19-361 to 146.37%
1-122 to 131.58%
13-242 to 131.58%
25-362 to 131.58%
Any number35 to 12.63%
Split17 to 15.26%
Trio11 to 17.89%
Four numbers8 to 110.53%
Line5 to 115.79%
Combination 0, 00, 1, 2, 36 to 113.16%

Playing a single number gives you a 35-to-1 chance. The roulette wheel statistically would have to spin 38 times for this number to hit. Thus, 2/38 of the spins go directly into the casinos pockets, which is equivalent to a margin of 5.26%.

European Roulette Statistics

European Roulette has 36 numbers as well as a zero, or 37 possible slots into which the ball can land. So if you bet on a single number, you have a 1 in 37 chance to win. Here are the probabilities for all the possible combinations in the table below:

Red1 to 148.64%
Black1 to 148.64%
Even1 to 148.64%
Odd1 to 148.64%
1-181 to 148.64%
19-361 to 148.64%
1-122 to 132.43%
13-242 to 132.43%
25-362 to 132.43%
Any number35 to 12.70%
Split17 to 15.40%
Trio11 to 18.11%
Four numbers8 to 110.81%
Line 5 to 116.20%

Playing a single number gives you a 34-to-1 chance. Statistically speaking the roulette wheel would need to spin 37 times for this number to hit, which represents an advantage of only 2.7% for the casino.

In conclusion

Simply put, don't play American roulette if you can avoid it. It has the additional slot, the double zero, and this makes the house advantage much higher during the game. Ideally you want to play European roulette exclusively if you can.
