Many roulette players like the challenge of playing American roulette, but others tend to shy away from it due to the extra zero pocket. European and French roulette both have 37 pockets and a house edge of approximately 2.7%. In the American variant, however, the presence of the double zero pushes the house edge up to 5.26%. As this format of the game depicts the worst possible odds for the player, it’s generally advised to go for the European or French variety if you want the best possible chance at winning.
