If you have played roulette before in a regular casino, then you already know how to play online roulette as well. The gameplay is the same, and the rules are very similar no matter if you play American, European, or French roulette. The differences between those two types are minimal, and between betting online and in a land-based place is no difference.
So, what you have to do is anticipate where the ball will land on the spinning wheel. You can bet on a certain number, you can bet on odds and evens (which means bigger winning chances, but a lower win), you can bet on colors – black or red, or you could bet on number series, as numbers 1-18.
The differences between American, European, and French styles in online roulette are the same as in land-based wheels.
The house edge on American wheel is higher, which means slightly lower winning chances. French roulette, on the other hand, has some special proprieties unlike the other two. The main one is the “La Partage” rule.
This rule could give you a small percentage of your bet back, which means that French roulette, compared with the other two types, offers something more you could use to your advantage. However, in online casinos, this rule might be often cut out.
