What is Roulette?

Roulette is a game of chance where players wager on various numbers or groups of numbers. Each bet has a different payout and odds. There are many types of bets, but they all fall into two categories; outside and inside bets.

The wheel consists of compartments painted alternately red and black and is numbered from 1 to 36. A green compartment labelled 0 is also present on American wheels.


Roulette is a game of chance that uses a spinning wheel with 38 (or on modern European/Latin American tables, 37) numbered divisions to determine the outcome of a spin. Its origins are obscure but fanciful tales abound. One theory suggests that it was invented by the 17th-century French mathematician Blaise Pascal, while another claims it was borrowed from the older games hoca and portique. Until about 1900, most encyclopaedias described the game with 38 numbers as being English in origin.
