The 1.4% is called the House Edge, the casinos' fee for running the game, employing dealers, and entertaining guests that aren’t gambling at the moment, and it exists because of the green zero on the roulette wheel. However, when you look closer at the roulette odds table, you see that while the payout is 1:1, the probability of winning the bet is only 48.6% so where did the other 1.4% go? The roulette odds are seemingly 50-50 for both outcomes, and the bet payout would be 1:1 you get double your money back. The red or black bet means that you can bet on one of the colors, let’s say red, and if the ball stops on any of the red numbers, you win, and any other color will lose. The most classic bet in roulette is the red or black bet.
