Information About Roulette
Roulette is a casino and gambling game named after the French word meaning "small wheel". In the game a croupier spins a wheel in one direction, then spins a ball in the opposite direction around a tilted circular surface running around the circumference of the wheel. The ball eventually falls on to the wheel and into one of 37 (in European Roulette) or 38 (in American Roulette) colored and numbered pockets on the wheel.
Wheel layout
The main pockets are numbered from 1 to 36 alternating 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 a green pocket numbered 0, and in American Roulette there is also a second green pocket marked 00.
Betting
Players can place a variety of 'inside' bets (selecting the number of the pocket the ball will land in, or range of pockets based on their position), and 'outside' bets (including bets on various positional groupings of pockets, pocket colors, or whether it is odd or even). The payout odds for each type of bet is based on its probability. There are usually posted rules for table minimum and maximum bets, and these rules usually apply separately for all of a players 'inside' and 'outside' bets for each spin.
