Roulette originated in 17th-century France, evolving from earlier spinning wheel games. The term "roulette," meaning "little wheel," reflects its design. By the 18th century, the game took on its modern form, influenced by European gambling practices, with mathematician Blaise Pascal playing a significant role in its development. Roulette gained popularity in European casinos, particularly in Monte Carlo during the 19th century, and solidified its appeal with the addition of the green zero pocket, which introduced a house edge.
