Turn On is a "game version" of the classic child's game of electricity. Players draw cards, set the timer, then attempt to follow the directions on the card within the allotted time (typically :15, :30, :45 or :60)

The "gimmick" in Turn On is that the instructions on the cards always involve the two players touching the metal bars projecting from the sides of the game, and at some point, each other. As the human body is capable of conducting a slight electric charge, completion of the instructions also completes the circuit and the game board buzzes (there is no sensate feeling - i.e. no one gets shocked) letting players know they have successfully completed the task. The team totaling the highest point total (based on the time allotted for completed cards), is victorious.

A number of blank cards also came with the original version to allow player "variations".
