US Patent 7559552 Coin roulette arcade game

An arcade game is disclosed having a rotating roulette type wheel with holes along a concentric circle of the upper face, and a coin track for carrying a coin from a player to the roulette type wheel at the position of the holes, which serve as targets. An optical sensor signals a microprocessor that a coin is entering the rotating playing field, and a second optical detector detects the nearest target and communicates a target value to the microprocessor. The microprocessor compares the timing of the coin passing through the coin track and the passage of the most proximal target, and awards the target value of the time between the two events is within a predetermined interval.
