ABSTRACT:
A simulated bowling game includes solid state logic circuitry for simulating the position of a bowling ball as it is rolled down the alley, for determining the simulated disposition of the pins upon impact by the ball, and for computing the score of each player after each simulated roll of the ball. In order to imitate the roll of a ball, a player selects an initial ball position and an initial ball direction. Encoders provide signals which correspond to the selected initial ball position and direction, and a random number generator provides a spin factor signal. A horizontal displacement signal is computed from the ball direction signal and the spin factor signal and is added to the ball position signal to establish the horizontal ball position at successive vertical positions along the alley. Pin disposition logic determines which pins will fall upon impact by the ball and is responsive to the horizontal position of the ball as it enters the pin target area, the ball direction signal, the previous status of the pins, and a random signal from the random number generator. A pair of pin status registers are provided for storing the current status of the pins and registering changes as pins are indicated as fallen by the pin disposition logic. A scoring pulse train generator is responsive to one of the pin status registers for providing a single pulse chain, a double pulse train, and a triple pulse train, which include, respectively, one, two, and three pulses for each fallen pin; the pulse trains are employed in the scoring logic. A pin display includes lamps which indicate which of the pins is standing; these lamps are controlled by signals from the other status register to indicate the current pin status. After a ball reaches the pin target area, a ball return sequence is established showing the ball returning down the alley back to the starting line.
