The player has six hours of game time to collect 36 puzzle pieces. Every time the player dies, 10 minutes are deducted from the total time. The puzzle pieces are assembled in groups of four. The puzzle pieces overlap so that three pieces can be assembled before the player realizes he must start over. Pieces may be in the wrong orientation, and the player may have to use the horizontal or vertical mirror images. Additionally, the puzzle pieces are randomized in every game. A completed puzzle forms a nine-letter password which lets the player reach Professor Atombender.
