Abstract

A laminated three dimensional jigsaw puzzle includes multiple pieces superposed with one another and each piece having a dimension different from the others. Each piece has bosses on top of the piece and recesses in a bottom face of the piece to receive the bosses of the adjacent piece.

1 . A laminated three dimensional jigsaw puzzle comprising: 
 multiple pieces combinably superposed with one another and each piece having a dimension different from the others.    
     
     
         2 . The laminated three dimensional jigsaw puzzle as claimed in  claim 1 , wherein each piece has multiple bosses formed on a top face of the piece and multiple recesses defined in a bottom face of the piece to correspond to the bosses of an adjacent piece so that the bosses are able to be received in the recesses of the adjacent piece to form a three dimensional pattern.  
     
     
         3 . The laminated three dimensional jigsaw puzzle as claimed in  claim 2 , wherein the bosses and the recesses of the same piece are mis-aligned with one another.
