A common roulette wheel

A Roulette is a gambling game that is most often played in a casino. Roulettes use a spinning wheel with slots numbered 0 to 36 as well as a small ball to land on the numbers. These numbers alternate in a red/black pattern, with the 0 being green. The players must bet on what number the ball will land on. In addition to betting on numbers, players can also bet on odd and even numbers, colors, and a combination of numbers.
