roulette

Roulette is a gambling game, where a little ball rolls around a wheel and people bet on what number it will land on. Go lucky 7! Outside a casino, roulette can refer to an unnecessarily dangerous gamble.

It doesn't take any skill — just a whole lot of luck — to win at roulette. The wheel itself is called a roulette wheel. The game was invented in eighteenth century France, and you can still play it in casinos all over the world (though you have to be over 21 to enter those casinos). Russian roulette is a game of chance where people basically bet their lives. In French, roulette means "small wheel," from the Latin root rota, "wheel."
