The earliest known mention of the mythical video game Polybius was an article on the otherwise legitimate arcade gaming fan site Coinop.org posted on August 3, 1998.

The article was edited on May 16, 2009, after the "game" had achieved viral popularity, to inform readers that the site hosts had received new information about the game and were flying to Kyiv, Ukraine to investigate the title, which they would update the page on when they found out. No news has been recorded on Polybius since, but the website would have new games added to its database up to 2021.

Kurt Koller, the webmaster for coinop.org, would later claim in 2021 that he planned to go to Kyiv in 2009 to see Chernobyl, but his friend from Ukraine refused because he was expecting a child, meaning that the "Polybius update" may have just been an in-joke related to this visit.
