At the bottom of the screen, you'll see blocks arranged in a line. Each block has points. The player drops a ball from the top of the screen, and it bounces off obstacles, heading toward the blocks. If the ball hits a block, it earns you points and destroys the block. If you manage to clear a full line of blocks, all lines below it rise by one level, and a new line of blocks appears from the bottom, giving you more opportunities to score. The key is to keep the ball hitting blocks as much as possible to maximize your score.
