Abstract

A jigsaw puzzle including a puzzle board, a plurality of puzzle pieces for removably placing on the puzzle board in a predetermined configuration, and control circuitry for automatically effecting a mechanical action visually discernible by a puzzle solver on successful assembly of the entire jigsaw puzzle. Exemplary mechanical actions include rotating a clock's hands, a vehicle's wheels, and the like.

1 . A jigsaw puzzle comprising a puzzle board, a plurality of puzzle pieces for removably placing on said puzzle board in a predetermined configuration, and control circuitry for automatically effecting a mechanical action visually discernible by a puzzle solver on successful assembly of the entire jigsaw puzzle.  
   
   
       2 . The puzzle according to  claim 1  wherein said control circuitry includes an electric motor for rotating an element mounted on a puzzle piece of said plurality of puzzle pieces for effecting a mechanical action visually discernible by a puzzle solver on successful assembly of the entire jigsaw puzzle.  
   
   
       3 . The puzzle according to  claim 1  wherein said control circuitry includes a one shot timer for automatically switching off said control circuitry a predetermined time after successful assembly of the entire jigsaw puzzle.  
   
   
       4 . The puzzle according to  claim 1  wherein said control circuitry illuminates at least one light emitting device on successful assembly of the entire jigsaw puzzle.  
   
   
       5 . The puzzle according to  claim 4  wherein a light emitting device backlights a non-opaque puzzle piece.  
   
   
       6 . The puzzle according to  claim 1  wherein said control circuitry includes a playback mechanism for playing back a pre-recorded soundtrack on successful assembly of the entire jigsaw puzzle.
