The goal of the ARG Perplex City (Mind Candy, 2005) was to find and recover the Receda Cube, a mysterious object stolen from the fictional city. The puzzle-based treasure hunt involved collecting trading cards and meeting other players to solve puzzles. Andy Darley eventually unearthed the cube, buried in Wakerley Great Wood, UK. He won the game’s £100,000 ($172,000) cash prize for his efforts.
