Ready Player One

Ten months after the first edition release, Cline revealed on his blog that Ready Player One itself contained an elaborately hidden easter egg. This clue would form the first part of a series of staged video gaming tests, similar to the plot of the novel. Cline also revealed that the competition's grand prize would be a DeLorean. The game Ultimate Collector: Garage Sale by Austin based developer Portalarium was featured in one part of the contest. The final stage of the contest was announced on August 1, and was to set a world record on one of several classic arcade or Atari 2600 games. This was completed on August 9 by Craig Queen, who set a new world record in Joust. He was awarded the DeLorean on the TV show X-Play.
