Perplex City is a long-term alternate reality game (ARG) presente by Mind Candy, a London-based development team. The first "season" of the game had players looking for "The Receda Cube" (referred to simply as "The Cube"), a priceless scientific and spiritual artifact to the people of a fictional metropolis known as "Perplex City", that had been stolen and buried somewhere on Earth. The game offered a real-life £100,000 reward (approx. $200,000 or €150,000) to whoever found it. Like most alternate reality games, the story of Perplex City is told through blogs, puzzles, and other various media.
