The object of the game is to surround the computer's cycle(s) with a trail of light. If your cycle runs into the side walls, or light from your or any of the other cycles, you lose a player. After each successful completion, either more computer cycles are added or they get faster.
You can move your cycle in all directions by using the control pad. Use the Fire button to speed up.
The game speed can be changed during the "Introduction" display. The speeds can be changed by using the control pad.
