[WorldUrbanLegend] Polybius
Polybius is a fictional arcade game from 1981 that appears in urban legends. This legend describes the game as part of a government-sponsored psychological experiment involving crowd participation in Portland, Oregon. It is said that the gameplay produced intense mental and addictive effects on players. Several publicly installed arcade machines were reportedly visited regularly by "black men" who collected data from the machines to analyze these effects. Ultimately, all Polybius arcade machines are said to have disappeared from the arcade market.
According to this urban legend, in 1981, when new arcade games were rare, an unprecedented new arcade game appeared in various suburban areas of Portland, Oregon. The game became so popular that it was addictive, often leading to lines forming around the machines and fights breaking out over who would play next. It is said that black men visited these machines to collect unknown data and allegedly test reactions to the game's mental effects. Players reportedly experienced a range of unpleasant side effects, including seizures, memory loss, insomnia, nightmares, and hallucinations. After its release in 1981, Polybius is said to have vanished without a trace about a month later.
The company most commonly mentioned in stories about this game is Sinneslöschen. Writer Brian Dunning describes this term as "improperly expressed German," meaning "sensory deletion" or "sensory deprivation." The word is derived from the German Sinne ("senses") and löschen ("to extinguish" or "to delete"), although the combination is not standard German. Sinneslöschen would be a more accurate expression.
The game is named after the classical Greek historian Polybius, who is known for asserting that historians should not report unverified content from interviews with witnesses.
The first online mention of Polybius is believed to be an article from coinop.org written in 1998, which claimed to own the ROM image file of the 1981 arcade machine and expanded the legend. On May 16, 2009, it even promised future updates while announcing plans for investigative flights over Kyiv, Ukraine. The first printed mention of Polybius appeared in the September 2003 issue of GamePro magazine, which contributed to popularizing the legend with a feature titled "Secrets and Lies," declaring the game's existence as "uncertain," thereby stimulating curiosity and spreading the story.
