Jigsaw is a BBC show aimed at children between the ages of 4 and 7 that combined elements of puzzle solving and entertainment, which was broadcast from 16 July 1979 until 15 June 1984.

Written and directed by Clive Doig, the show was presented by mime artist Adrian Hedley, Janet Ellis and "Jigg" - a giant floating orange jigsaw piece, voiced by John Leeson later replaced by Tommy Boyd then Howard Stableford.

Ellis left in 1983 to become a Blue Peter presenter, at which point she was replaced by Dot, played by Julia Binsted - an anthropomorphism of the "cursor dot" (the dot made by the raster-scanning beam in the analogue CRT television sets of the time).

Featured supporting cast also included Paul Clayton, Biggum the giant (played by Leeson) and Wilf Lunn who appeared as a mad inventor. Other unusual characters included Pterry, a puppet Pterodactyl (operated by Joe Barton); Cid Sleuth (played by David Cleveland), a Sherlock Holmes-looking bumbling detective plagued by a mysterious burglar (David Wyatt); Hector The Hedgehog; and the O-Men (Sylvester McCoy and David Rappaport), a pair of hapless superheroes summoned by saying any six consecutive words containing a double-O (even the same word repeated six times counted once, albeit inadvertently - Dot said 'coo' four times imitating a pigeon, then Adrian mocked her attempt, saying it twice more to trigger the summon).
