The game of American Roulette is played on a wheel which presents 38 numbers containing boxes 0 and 00. The presence of these two zeros decreases the possibilities of the players and increases that of the casino. The game is played with a ball and a carpet. The numbers alternate between black, red and even, odd. The house advantage is here is merely 5,26%

A dealer spins the wheel in one direction and then rolls a small ball in the other direction. The ball then drops into one of the slots as it begins to slow down. 

The object of the game is extremely simple: players must guess in which slot of the roulette wheel the ball thrown by the dealer will end. They thus predict the winning number by placing their chips on a carpet installed in front of them where all the numbers entered on the roulette wheel are represented with their respective colors.
