Roulette is a casino and gambling game (Roulette is a French word meaning small wheel). A croupier turns a round roulette wheel which has 37 or 38 separately numbered pockets in which a ball must land. The main pockets are numbered from 1 to 36 alternate between red and black but the pockets are not in numerical order around the wheel and there are instances of consecutive numbers being the same color. There is also a green pocket numbered 0 and in most roulette wheels in the United States but not in Europe there is a second green pocket marked 00. If a player bets on a single number and wins the payout is 35:1 meaning that for each dollar bet one wins an additional $35.00. After determining winning wagers and paying them off casinos commonly leave winning bets on the table. The player is not obliged to leave that bet down but if removing it should wait until the glass pawn (or other similar marker) has first been removed by the croupier. Other betting options with lower payoffs include bets on multiple numbers in various combinations or ranges on all odd or all even numbers or by color.
