     Polybius is a mysterious arcade game that is still shrouded in secrecy to this day. The lack of knowledge about the Polybius case has led to a couple of conspiracy theories. 

1. Was Polybius a government experiment that the only known survivor, Bobby Feldstein, was able to escape? 

2. Did Polybius even exist at all? 

Although the enigma that is the Polybius case is still debated even today, the most likely explanation is that Polybius never existed in the first place.
