There is one bat per side, a top and bottom boundary, and a center net. The individual scores are counted and displayed automatically. Considering the option where all bats and four angles are used, after the reset has been applied, the score will be 0-0 and the ball will serve arbitrarily to one side at one of the angles. If the ball hits the top or bottom boundary it will assume the angle of reflection and continue in play. The player beeing served must control his bat to intercept the ball. When a hit is detected by the logic circuit, the section of the bat which made the ball contact is used to determine the new angle of the ball. To expand on this, all bats are divided logically into four adjacent sections of equal length. When using the four angle option, it is the quarter section of the bat which actually hits and determine the new direction of the ball. The direction does not depend upon the previous angle of incidence. With the two angle option, top and bottom pairs of the bats are summed together and only the two shallower angles are used to program the new direction of the ball. The ball will be then sent back to the other player, bouncing on top and bottom boundaries as necessary until it reaches the other player.

This action is repeated until one player misses the ball. The circuitry then detect a score and automatically increments the correct score counter and updates the score display. The ball will then serve automatically towards the side which has just missed. This sequence is repeated until a score of 15 is reached by one side, meaning the end of the game. The ball will still bounce arround but no further hits or scores can be made. While the game is in progress, 3 audio tones are generated by the system to indicate top and bottom reflections, bat hits and scores.
