The rules of roulette are very simple. In this game, you have a wheel with red and black slots, numbers from 1 to 36, and one or two green zero slots - depending on whether you are playing European single zero roulette or American double Zero roulette. In addition to the steering wheel, you have a table with numbers and a few extra sectors that you can bet. After all the participants in the game have placed their bets on the table, the dealer turns the steering wheel and throws a small ball. The number of slots in which the ball falls is the winning number.
