When someone bets on a roulette game, they are essentially placing a bet on the number that will come up on the wheel. Roulette wheels have 36 numbered slots, and each slot can hold either a black or red ball.
The balls are randomly placed into the slots, and from there the roulette wheel starts to spin. Roulette wheels typically rotate around 600 revolutions per minute, which means that it would take about 36 seconds for the wheel to complete one full rotation. .
As a result, roulette players often refer to the time it takes for the wheel to spin as “the house edge.” The house edge is the percentage of the time that a player will lose money by playing roulette. In general, the house edge ranges from 0.6% to 2.
6%. This means that for every 100 times that a roulette player bets on a number, they will lose 66 of those bets (or 6%).
