Lloyd King is a puzzle designer living in the UK.
King specialises in creating novel and unusual puzzles with "Aha!"
Many lateral thinking puzzles are open ended, with numerous possible correct answers, but King strives to create puzzles with a single answer, which should become obvious with the illuminating "Aha!"
He has written a number of books, and his puzzles are often quoted and used as illustrative examples in works by other authors, including "Riddles of the Sphinx" by David J Bodycombe.
King's puzzles have also appeared in the "Get Smart in a Week" creativity test on BBC1 in 2006, in OMNI, The Times, The Independent, GAMES and various other publications, games and advertising.
