There are two main types of roulette: American and European. The American wheel has 38 numbers (1-36, plus 0 and 00), while the European wheel has 37 numbers (1-36, plus 0). The house edge on the American wheel is 5.

26%, while the house edge on the European wheel is 2.7%.

The house edge is calculated by taking the total number of possible outcomes and subtracting the number of winning outcomes. For example, in American roulette there are 38 possible outcomes (37 if you’re playing European roulette). Of those 38 outcomes, only 37 are winning outcomes (because 0 and 00 are losing numbers). So, 37 – 38 = -1.

PRO TIP:To calculate the house edge in Roulette, first determine the probability of winning for each bet type. For example, if you are playing American Roulette, a bet on red or black would have a 48.65% chance of winning since there are 18 red numbers and 18 black numbers out of 38 total. Then take the probability of winning (48.65%) and subtract it from 100% to get the house edge (51.35%).

The house edge is therefore -1/38, or -2.63%.

Roulette is a negative expectation game, which means that over time, you will lose money if you play it. However, it’s still a popular game because it’s easy to understand and it can be quite exciting.

If you’re going to play roulette, it’s important to know how to calculate house edge so that you can manage your bankroll and keep your losses to a minimum.
