European wheels have only one zero, giving the player a better chance of winning. | Roulette By Country | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Casino Edge Affect the PayoffLet's calculate how the casino's edge affects the payoff of a wager on our favorite number, seventeen. We have already calculated the probability of the number showing, which is 1 out of 38 or 1 to 38. If the house did not have an edge over the player, the correct payout for winning the wager would be the real odds against winning the bet, which is 37 to 1. However, the house gains an edge by shortchanging the player on the payoff of a winning bet and only pays the wager at 35 to 1. The house keeps 2 out of the 38 numbers for itself. These numbers are the zero and double zero. The house edge over our bet on the number 17 can be calculated as follows: Wheel with zero and double-zero - 2/38 = 0.0526 or 5.26% Wheel with one-zero - 1/37 = 0.027 or 2.70% As we shall see later, some casinos use a special rule for roulette's outside bets which allows the wager to stay up for an additional spin after a zero appears. In this case the bet is said to be imprisoned. This rule lowers the house edge even more. | Online Roulette Software ProvidersBetSoft RouletteMicroGaming RouletteNetEnt RoulettePlaytech RoulettePlay’n Go RouletteRTG RouletteWMS RoulettePlayson RouletteNYX RouletteEndorphina RouletteiSoftBet Roulette | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
