Gyron was originally released in 2 parts, Gyron Atrium
and Gyron Necropolis
. The first person to solve the puzzle in the Necropolis would win a Porsche 924 motor car or £12,500 cash. Since around 60 people did, a play-off was simultaneously organised in London, Spain and Denmark for a third challenge, specifically written for the event, Gyron Arena
. The winner solved the puzzle in 18 minutes.
Afterward, Gyron Arena
was published on budget.
