Puzzle and playing method using puzzle

Abstract

A puzzle includes a plurality of pieces having the same outer shape, the plurality of pieces are divisionally arranged in a plurality of layers, and the pieces assigned to each of the plurality of layers are selectively arranged at locations on a plane of the layer. Each of the plurality of pieces includes an opaque part, and at least one of the plurality of pieces further includes a transparent part. The opaque parts of pieces assigned to a given layer are formed to cover, of true patterns and dummy patterns on a lower side of the layer, the dummy patterns, and the true patterns seen through the transparent parts of the pieces are combined to form one pattern.

1 . A puzzle including a plurality of pieces having the same outer shape, wherein
 the plurality of pieces are divisionally arranged in a plurality of layers, and the pieces assigned to each of the plurality of layers are selectively arranged at locations on a plane of the layer,   each of the plurality of pieces includes an opaque part, and at least one of the plurality of pieces further includes a transparent part, and   the opaque parts of pieces assigned to a given layer are formed to cover, of true patterns and dummy patterns on a lower side of the layer, the dummy patterns, and the true patterns seen through the transparent parts of the pieces are combined to form one pattern.   
     
     
         2 . A puzzle according to  claim 1 , further comprising a base member having a base of the one pattern formed on an entire surface, the base including the true pattern and the dummy pattern,
 wherein pieces of a lowermost layer are arranged on the base member.   
     
     
         3 . A puzzle according to  claim 2 , wherein
 the plurality of layers include an upper layer and a lower layer,   the opaque parts of the pieces assigned to the lower layer are formed to cover portions other than the true patterns and the dummy patterns, and   the opaque parts of the pieces assigned to the upper layer are formed to cover at least the dummy patterns.   
     
     
         4 . A puzzle according to  claim 1 , wherein
 the plurality of layers include an upper layer and a lower layer,   the opaque parts of the pieces assigned to the lower layer form true patterns and dummy patterns, and   the opaque parts of the pieces assigned to the upper layer are formed to cover at least the dummy patterns.   
     
     
         5 . A puzzle according to  claim 1 , wherein the pieces are made of a transparent material, and the opaque parts are formed by coloring the transparent material. 
     
     
         6 . A puzzle according to  claim 1 , further comprising a storage box which divisionally stores the plurality of pieces in the plurality of layers,
 wherein each of the plurality of pieces has a rectangular outer shape.   
     
     
         7 . A playing method using the puzzle of  claim 6 , comprising the steps of:
 in a state in which the plurality of pieces are divisionally arranged at predetermined positions in the plurality of layers in the storage box, removing one piece of the pieces arranged on an uppermost layer; and   moving the remaining pieces arranged on the uppermost layer in vertical and horizontal directions using a free space corresponding to the removed piece, thereby completing the pattern.
