The size of a roulette wheel can vary depending on the casino or game being played. The most common size is a 37-pocket wheel, which is used in European roulette games. This size wheel has 18 red pockets, 18 black pockets, and one green 0 pocket.

PRO TIP:When purchasing a roulette wheel, make sure it is the standard size of 37 centimeters (14.5 inches) in diameter. A wheel that is either larger or smaller than this size could affect the outcomes of the game.

The American version of roulette uses a 38-pocket wheel that has two green 0 pockets instead of just one. This variation gives the house an even greater edge over players.

No matter what size wheel is being used, the odds of any given bet remain the same. A bet on a single number has a 1 in 37 or 1 in 38 chance of winning, depending on the variation being played.

The house always has an edge over players in roulette, so it is important to remember that no betting system can guarantee wins.
