What are the odds in roulette? The roulette odds of winning a round depend on the number of outcomes covered in the bet. If you bet on only one number, you are facing 1-in-37 odds in European roulette and 1-in-38 odds for the American version. In both cases however, the roulette payout for straight bets is 35:1.
Say a single-number bet has a 35:1 payout, and you betR$1. If you win, you'll get your money back plusR$35. Another example: If you win aR$100 bet (for a 35:1 payout), you get a total of $3,600 ($3,500 profit plus theR$100 you initially bet).
