European Roulette has a wheel with 37 positions labelled 0 to 36. Positions 1 through 36 are marked with alternating red and black backgrounds and position 0 has a green background. Bets are placed on various positions on the table that correspond to different numbers, combinations of numbers, odd/even or red/black. After bets are placed a small ball is set in motion around the outer rim of the roulette wheel in the opposite direction of the spinning wheel. When the ball comes to rest in a numbered position, non-winning bets are cleared from the table and winning bets are paid according to the paytable.
