During the game, the players place their left hands on the PEU (Pain Execution Unit) which serves as a sensor and feedback instrument.
The following bonus items can be activated by hits in the current version of the software in 2006: No matter the score, the first player to remove his or her hand from the PEU device loses the game.
Apart from adjustable pain levels, it offers several replaceable whips and an additional source of light which players can use to produce glare on their opponent's side of the screen.
The higher processor performance makes it possible for the system to control the speed of the whip engine and the strength of the electric current individually.
It is equipped with a 15-inch LCD monitor and it was shown to the public on June 25, 2003 on the German Harald Schmidt television show.
Newly added fans in the PEUs cool the system down better between games to avoid electronic problems and can serve the players if they hit the right bonus item.
