When determining your roulette odds you must take certain factors into account. The most important is whether the roulette wheel has a double zero slot. Most roulette wheels in the United States have both a zero and double zero. Under standard U.S. roulette rules the house edge is 5.26% for double zero wheels, except for the 0-00-1-2-3 bet which has a house edge of 7.89%. |

Single zero roulette wheels can be commonly found online and outside of the United State. The odds for a single number changes from 1/38 to 1/37 on single zero tables. This drops the house edge to 2.70%. In standard U.S. casinos these tables are generally only found in high roller rooms. |

There are several variations of the "en prison" rule that also affect the house edge. In Atlantic City all even money bets follow a variation of this rule. In the event the ball lands in 0 or 00 the player will lose only half of any even money bet. This lowers the house edge to 2.63% on these bets. This rule does not apply on single zero wheels. On single zero roulette tables using the European "en prison" rule the house edge drops to somewhere between 1.35% and 1.39% for even money bets depending on the variation of the rule. This rule does not affect non even money bets. |
