Roulette, meaning ‘small wheel’ in French is a popular casino gambling game. A croupier spins a Roulette wheel and introduces a small ball into the spinning wheel, which has 37 or 38 numbered pockets in which the ball will land. The main pockets, which are alternately red and black, are numbered from 1 to 36 starting with a red number 1. The 0 is colored green. In roulette wheels in the U.S., but not in Europe, there is a 00 which is also colored green.

If a player’s bet on a single number comes up, he will win at odds of 35 to 1. The bet itself is returned, so in total his bet is multiplied by 36.

Bets are placed on single numbers, combinations of numbers, ranges, odds/evens and red/black.
