  • Patent number: 6520854
    Abstract: A roulette wheel assembly and table arrangement includes a roulette wheel rotatably mounted in a wheel bowl, and driven by an electric motor. Thirty seven slot compartments are located around the wheel circumference to receive a roulette ball. In operation the wheel is rotated and the slot compartment floor is lowered to allow a ball from the previous game to be thrown outwardly and fall into a ball magazine. A firing breech is opened to allow a ball to enter a firing chamber. On the command, an air blower blows the ball into a firing tube which propels the ball tangentially onto the bowl in the opposite direction to the travel of the wheel. The ball travels across the bowl onto the wheel and finally lands in a compartment. Each player around the table has a betting station giving the betting choices that make up the game.
