Puzzles consisting usually of irregularly cut pieces of pasteboard or wood that when fitted together form complete pictures; historically, the images would not include maps nor would they purport to have an educational emphasis. For similar puzzles of maps, with an educational function, popular from the mid-18th to the early 19th century, use "dissected maps." For puzzles with tightly interlocking pieces made with a jig or jigsaw, use "jigsaw puzzles."
