Roulette Game Odds

Roulette, like craps, is an independent variable game where luck determines the winners. An air of sophistication graces the table and the possibility of winning up to 35 times your bet creates an enticing lure for many players. The odds in roulette are easy to calculate. The wheel is divided into either 37 or 38 slots, depending on whether you are playing the European version (single zero), or the American version which has an extra space in the double zero. The zero space(s) represent the house edge. If there were none, it would be an even money game. The house advantage in single zero roulette is 2.7% and for the double zero game it is 5.26%.

Looking at the chart above, you'll find the European single zero game offers the same payouts, but better odds than the American double zero game on account of there being one fewer slot on the wheel. While it is rare to find the single zero game at a casino in America, this game is standard among online casino sites. Online casinos generally offer better odds than those found in land casinos across the board, and this holds true for the game of roulette.  



Bets To Avoid

The bets to avoid in this game are probably all single number bets and the five number bet (only found on double zero wheels) because these types of bets have the largest disparity between true odds and actual payouts.



Best Bets

If you plan to play online roulette, stick with the bets whose odds almost mirror their payouts. These 'even money' bets include betting on Even, Odd, Low (numbers 1 through 18), High (numbers 19 through 36), Red, or Black. All of these wagers pay out at 1 to 1.
