The game consists of four handles each equipped with a button. Each player grabs a handle and the game is started. A red light starts to blink and a nasty wailing sound is played. Suddenly, the light will turn green and the sound will go silent. At that point, players must push the button on their handle. The last player to do so gets an electrical shock. A player will also get shocked if they push the button too soon--while the light is red.
The game uses three AAA batteries, so the shock isn't dangerous, but it certainly adds an element of tension to an otherwise rather simple test of reaction speed.
