The game of roulette traces it's origin to England in the early 1700s in a game called Roly Poly. It featured black and white spots with no numbers. The French redesigned it in the late 1700s to include numbers. Original American wheels had 31 numbers plus a 0, 00, and an american Eagle for the third zero number. Today's European roulette wheels usually have only one zero while most American wheels have a zero and a double zero. Both the American and European modern wheels have 36 numbers. Roulette is the most popular casino game in Europe.
