In the version for the NES, the player must avoid being caught by Harry and Marv for 20 minutes. During this time, Kevin can set various traps using items scattered around the house, each with a different corresponding strength and allowing the person tripping them to be knocked unconscious longer. Kevin can also hide behind certain parts of the house, but only for two consecutive turns; any other concurrent passings will result in a game over.
