Roulette
(sometimes known as 'rulet') is a casino game named after a French diminutive
for "little wheel". In the game, players may choose to place bets on either a
single number or a range of numbers, the colors red or black, or whether the
number is odd or even. To determine the winning number and color, a croupier
spins a wheel in one direction, then spins a ball in the opposite direction
around a tilted circular track running around the circumference of the wheel.
The ball eventually loses momentum and falls on to the wheel and into one of 37
(in French/European roulette) or 38 (in American roulette) colored and numbered
pockets on the wheel.[1]
