To illustrate, if you bet $1 on the number ‘12’ and it hits, you’ll be paid $35, plus your bet back, for a total of $36. This gives the house a slight edge of 2.6 percent (more in American roulette).
On a European roulette wheel, the payout for hitting a single number is 35-1, yet the odds of it happening are 37-1. The odds of real money roulette are fixed and they payouts are slightly less than the actual odds of the outcome. The odds are built into the game and they are always in the house’s favor. The answer is that it’s very hard to beat the roulette wheel. For centuries, mathematicians, physicists and players have tried to beat the game of roulette.
