Seasoned roulette buffs favor single-zero tables because they are fighting a smaller house edge in such games. In roulette, the house gets its edge through the addition of the zero pocket. If it wasn't for the zero, you would play a game of even chances, or at least with bets on number properties. The house take single-zero tables yield is 2.70% (1.36% with La Partage and En Prison). The addition of the 00 pocket on the double-zero wheel almost doubles the house edge, boosting it to 5.26%.
