Score 4

Score 4 is a 1-player arcade game for the TRS-80.

Nineteen balls are dropped one at a time into a 4 x 4 vat containing the numbers 1 - 16. The ball slowly drops down to lower positions, while moving left and right. The player tries to press a key, when the ball is sitting on a number, removing that number from the board. If the player selects a key on an empty space, that ball is lost. The player scores points for removing 4 in a row, the 4 outside spaces, or the 4 inside spaces, to a maximum score of 19. There are 9 levels of ball speed, and balls can also be lost by hitting the bottom of the vat.
