Peek-a-Boo! (Japan, ver. 1.1) — About this game
Peek-a-Boo! (Japan, ver. 1.1) makes a cleared brick pattern the condition for revealing its picture reward. The paddle travels along the lower screen and rebounds the ball into the remaining bricks. Letting the ball escape below loses the current chance to keep clearing, while another complete pattern advances the sequence of adult pictures. Rewards include male as well as female subjects. Follow the descending ball before looking at the uncovered image, then work toward the last isolated bricks rather than repeatedly sending it through an already cleared gap.
