The exact origins of the game are obscure, but it seems to have evolved from "pitch and toss", a gambling game involving tossing a single coin into the air and wagering on the result of the toss which was popular amongst poorer English and Irish citizens in the 18th century. The prediliction of the convicts for this game was noted as early as 1798 by the colony's first Judge Advocate, as well as the lack of skill and consequent losses at it.

Roulette is a casino and gambling game (Roulette is a French word meaning "small wheel"). A croupier turns a round roulette wheel which has 37 or 38 separately numbered pockets in which a ball must land. The main pockets are numbered from 1 to 36 and alternate between red and black, with number 1 being red. There is also a green pocket numbered 0. In most roulette wheels in the United States but not in Europe, there is a second zero compartment marked 00, also colored green.
