There are 36 numbers on a roulette wheel. If a player bets on any number other than the number 1, the house edge against that bet is 2.17%. If the player bets on number 1, the house edge is 0%. This means that for every $100 bet on a roulette wheel, the player would expect to lose $2.17.
However, if the player bets $10 on each number in turn, they would win back their original investment of $100 since no number comes up more than once. In total, if a player bets $100 on a roulette wheel and each number comes up only once, they would win back their original investment of $100 plus $10 for every turn they bet. This means that the total amount of money won or lost on a roulette wheel is equal to the sum of all the numbers on the wheel minus the house edge which is 2.17% ($101 – 2.17%).
