Roulette was an Earth game of chance. The object of the game was to predict where a ball dropped onto a rotating wheel would land once the wheel had stopped moving. It was similiar to Dabo.
In 2365, William T. Riker, Data, and Worf observed, among several other games, roulette tables in the casino of the recreated Hotel Royale on Theta VIII. (TNG: "The Royale")
Vic's Las Vegas Lounge had a roulette table. In 2375, Frankie Eyes invited Kira to "hit the roulette table." (DS9: "His Way", "Badda-Bing, Badda-Bang")
