One of the traditional casino games is that of roulette. Roulette is a game where players place wagers on the results of a wheel spin and where the ball lands. On a typical roulette wheel in the United States there are 38 pockets while typical European roulette wheels have 37. The roulette wheel consists of pockets of alternating colors and is numbered from zero. The game is played with players placing bets based on a number of different scenarios. 

Players can bet on the exact number that the ball will land in, the color of the pocket that the ball will land in, and players are also allowed to place a wager on a range of numbers located next to each other that they anticipate the ball to land in. In addition to the red and black, there are also the green zero and, in American roulette, the green double zero.

The existence of the green pockets allows the house to maintain an edge when players bet purely on the color of the spin. After players place their bets, a croupier spins the wheel in one direction and then spins the ball in the opposite direction. The wheel and ball rotate and, as the ball loses momentum, it drifts down the outside of the wheel and comes to rest in a specific pocket. Once the wheel has stopped turning, the number and color of the pocket are announced and the wagers are settled. Don't play at unproven online casinos, try our list of best online casinos.
