Every spin of the roulette wheel has an independent outcome and is uninfluenced by previous spins. Even if you get ten black numbers in ten spins, your chances of getting red are the same as getting black.

Roulette is a game of chance. You need to be able to determine the odds of winning and then place the best bets. American and European Roulette Roulette’s odds of winning are easy to calculate.

Whether you’re playing the European version (single-zero) or the American version with an extra slot in the double zero slots, the wheel can be divided into 37 or 38 slots.

The house edge is represented by the zero space(s). The house advantage in single zero Roulette stands at 2.7%, while 5.26% for double zero.

How to Calculate Roulette Odds

  • European Single Zero Game American Double Zero Game
  • (35-36)/37×100 = -2.7% (35-37)/38×100 = -2.20% (35-37)/38×100 = -5.2% (35-37)/38×100 = -5.2%

Beware of these Bets

Avoid single-number bets and five-number bets. These bets are only available on double-zero wheels and have the greatest disparity in odds and actual payouts.

Place your bets

Roulette is a game that you should play. Stick with bets that have odds that are close to their payouts. These “even money” wagers include betting on even, odd, low (numbers 1 through 18,), high (numbers 19 to 36), red, or black. These wagers pay at 1 to 1.

Roulette Odds: The Best Bet on the Table

You should look for a European single zero wheel that provides the rule “en prison.” If the ball lands on zero in an even-money wager, the croupier does not rake in your bet. Your bet will instead be ‘imprisoned’, or taken hostage. You are then forced to keep it on your table until the next spin. You can take your winning bet off the table if it wins.

This bet reduces the house edge for even money bets by half to just 1.3%
