Roulette - A wheel features red and black slots that have the numbers from 1 to 36 on them and two green zero slots. The table features the numbers and several additional sectors on which you can place bets. After all the participants in the game have placed their bets on the table, the dealer spins the wheel and throws in a small ball. Whichever is the number of the slot the ball lands in is the winning number. If you have bet on that number or on a group of numbers that contain it, you win.
