What is Roulette?

Roulette is a casino game played with a small ball and a wheel. Players place bets on specific numbers or various groupings of numbers, the color red or black, and whether the number is odd or even or high (19-36) or low (1-18).

A roulette wheel consists of a slightly convex wooden disk with thirty-six compartments that are painted alternately red and black and numbered 1 to 36. On European wheels a green compartment carries the number 0.
