|a puzzle in which the player has to reassemble a picture that has been mounted on a wooden or cardboard base and cut into a large number of irregularly shaped interlocking pieces|
any set of varied, irregularly shaped pieces that, when properly assembled, form a picture or map. The puzzle is so named because the picture, originally attached to wood and later to paperboard, was cut into its pieces with a jigsaw, which cuts intricate lines and curves. Jigsaw puzzles may be very complicated vis-a-vis the number of pieces and the number of different cuts and thus take many hours to complete
