Players control Tamagon, a green dragon who decides to "attack the Devil's World", along with a red Player 2 version of him. He navigates through a series of mazes and touches crosses to power up and summon the ability to breathe fire and eat the dots in the maze. Without a cross, he is completely helpless, and cannot complete the maze. The large winged demon simply called "the Devil" dances at the top of the screen, and will point in a direction for four of his minions to move the maze by using pulleys and ropes. This can be dangerous, as Tamagon can be squished by getting caught between a maze wall and the moving outer boundary. After the first maze is cleared, the next objective is to get four Bibles, and put them into a seal. The Bibles give Tamagon the same powers as with the Crosses. After carrying them all into the seal, the Devil flies to the next maze. In between, a bonus maze shows up where Tamagon collects six Bonus Boxes under a time limit. The pattern then repeats.
