Polybius

Sinneslöschen translates from German as Sense-Delete.

The true history of Polybius remains obscure. The game is reported to have been released into a small number of Oregon arcades in a suburb of Portland. After playing, players reported a number of problems including sleep disturbance, nausea, and game aversion. These effects spawned a number of rumors ranging from government mind-control experiments to the supernatural. The game's existence is dubious and details regarding possible gameplay and buried beneath layers urban myth.

A Polybius machine was featured as a gag in the September 24, 2006 episode of The Simpsons, titled "Please Homer, Don't Hammer 'Em...". In an arcade full of '70s/'80s arcade machines, Polybius can be seen in the background. On its panel only one button can be seen, presumably the start button. To further the spoof, the front of the machine was printed with the words 'property of US Government'.
