When the robot comes into contact with a machine, it gives it the option of gamble for an extra life or for its death. The droid can also decline to gamble, leaving the machine activated and an bonus is awarded, depending on how much remaining energy the droid has.
Each room is filled with a variety of hazards; including meanies that regenerate when shot at, and laser beams and sliding blocks that must be avoided. Starting from the first room that the droid enters, its energy quickly drains, meaning that the droid needs to find a machine as quickly as possible.
