For example, consider the straight number bet in the European variation. With 37 numbers on the wheel, including zero, your chance of winning is 1/37. However, the payout if you win this bet is set at 35 to 1. Therefore, if you bet $1 on all possible numbers, you will lose $37 of your bet. Meanwhile, you’ll get $36 back on the payout, which includes $35 of your winnings and $1 of your winning bet refunded. In the end, the casino will be the beneficiary with $1 of profit ($37 minus $36). Therefore, the difference between the winning odds and the payout odds is the basis for casinos to stay profitable and continue to offer the game. In the long run, the casinos always have the edge, regardless of the wheel’s outcome.
