Stuart Landsborough's Puzzling World is a tourist attraction near Wanaka, New Zealand. It started out as just a maze in 1973, but over the years expanded to accommodate a "puzzling café" where guests could try out several puzzles, rooms with optical illusions, the Leaning Tower of Wanaka (which has a backwards clock that was started on the eve of the new millennium) and other things. The operators of Puzzling World have for many years offered a monetary prize for anybody who can prove themselves to have psychic powers; all a potential winner needs to do is use their powers to locate a specific item located somewhere in Puzzling World's environs. To date the prize goes unclaimed, although only 6 'professional' psychics have attempted the challenge. The biggest challenge, a huge maze in which the traveller must reach four towers while navigating the maze.
