of the night's escapades anything could happen." An "armchair treasure hunt" is an activity that requires solving puzzles or riddles in some easily portable and widely reproduced format (often an illustrated book), and then using clues hidden either in the story or in the graphics of the book to find a real treasure somewhere in the physical world. This type of treasure hunt may take months to solve and often has large prizes to be won. An early example of the genre is Kit Williams' 1979 book Masquerade while games still in play include The Secret and On The Trail of the Golden Owl. An unusual example of the armchair treasure hunt is the book MAZE: Solve the World's Most Challenging Puzzle by Christopher Mason, with the publishers awarding a prize of $10,000 USD to the reader who deciphered and solved a riddle using clues in the book's illustrations. Ultimately the prize was split among the twelve readers who came closest to the solution. The contest is now void, though MAZE remains in publication. In 1956, comedian Jan Murray created and hosted a variation for television, also known as Treasure Hunt. This US game show featured a pair of contestants answering questions to qualify to go on a treasure hunt that involved choosing from among thirty treasure chests that included anything from gag prizes to valuable merchandise and/or cash. The show also offered home viewers a chance of a treasure hunt, when a postcard was chosen from a large drum by a young guest who revolved the drum several times to randomise the entries. The show aired daily in the morning and once a week in the evening until 1959, when the networks began canceling game shows in the wake of the quiz show scandal. In 2012, the Guinness World Records title for 'most participants in a treasure hunt game' was set by Team London Ambassadors, who broke the previous record (of 308 participants) in London. 466 Participants, all London Ambassadors for the Olympic and Paralympic Games, worked in 93 teams of five, each completing a set of twelve clues hidden on either side of the River Thames, starting and finishing at City Hall, London. The treasure hunt in the form of a spy mission game formed part of World Record London for 2012. A separate points competition was held with one team emerging the winner of the 'treasure'. Internet
