Amateur archaeologist Andy Darley has discovered the Receda Cube, ending the first season of alternate reality game Perplex City and earning a hefty $200,000 reward (before taxes). Darley was joined by more than 50,000 other registered players, spread throughout 92 countries, on the two-year hunt. The cube was unearthed in Wakerley Great Wood, England, about 110 miles north of London.

Perplex City's first season was "played" using a deck of cards (collectible in packs) that featured various types of puzzles, from simple trivia to optical illusions; to an answer masked with heat-sensitive ink. Solutions often pointed players to further clues posted on websites, written in books, recorded in voicemails, and held by real-world individuals. Creator Mind Candy has confirmed that plans for a second season are underway.
