Several Companies make these jigsaw puzzles. They take two basic forms: 1. A short back story is provided while the picture in the jigsaw puzzle provides the primary challenge. 2. A full blown story is provided for which the jigsaw puzzle picture provides clues.
These puzzles are light, easy stuff but a worthwhile distraction none the less.
