The roulette wheel

The main element in roulette is, of course, the roulette wheel. There are several kind of wheels. The most common casino roulette must have certain dimensions due to regulations. It must be 80 cm (32 inches) in diameter. You can find smaller ones in social clubs (45 to 70 cm) and even smaller ones in home games. Typically, wheels are made of wood, but some can be made of other materilas such as plastic or sintetic material.
The most important variation in roulette wheels has to do with the layout. It varies according to the kind of game played. The two most common variations are the American wheel and the European wheel.
Both of them have numbers from 1 to 36. European wheels also have a green well marked 0 and american ones have the same numbers only with two green wells marked 0 and 00. As you can see on our article “casino´s edge” the single zero wheels give the house and edge of 2,70% while the American wheel has an edge of 5,26%.

When it comes to online roulette, wheels can be even more diverse. Some have extra wells (like an extra yellow bonus well in some double bonus roulette) and others have some part of the wheel marked for new different kind of bets. Wheel variations are appearing so therefore new roulette wheels are being created continuously.
Of course, table´s layout have some variations too, adding additional sections to wager. Our advice is to check your casino´s rules and stay away from bets you don´t fully understand.
