3d puzzles with replaceable tiles

Abstract

A logic cube with changeable tiles is presented. The tiles which can be fit on the logic cube, have indicia in well-defined positions and orientations such that the resulting solid is an exact but larger replica of the initial logic cube. The tiles are such that they can be easily fit or removed, and do not fall off with the movement of the logic cube. They also do not obstruct the functionality of the logic cube. Other geometric shapes such as tetrahedron and dodecahedron and sizes other than 3×3×3 may be used.

What is claimed is: 
     
         1 . A logic puzzle comprising:
 a first geometric solid having a first predetermined number of visible outer faces, the first geometric solid comprising a plurality of second geometric solids, the plurality of second geometric solids each having a second predetermined number of visible outer surfaces;   the second geometric solids each being rotatable within the first geometric solid such that at least one visible outer surface of each second geometric solid comprises a portion of one of the faces of the first geometric solid for at least one rotatable orientation of the plurality of second geometric solids within the first geometric solid; and   at least one indicia disposed on the at least one visible outer surface of the second geometric solid,   wherein a pattern is created by a plurality of indicia, and each of the indicia are coupled to an indicia on another surface.   
     
     
         2 . The logic puzzle of  claim 1 , wherein the at least one indicia comprise a sticker. 
     
     
         3 . The logic puzzle of  claim 1 , wherein an indicia of the at least one indicia has a desired orientation that stays true after any numbers of moves/rotations of the layers of the first large geometric solid. 
     
     
         4 . The logic puzzle of  claim 1 , wherein a meaningful expression is created by a collection of the indicia. 
     
     
         5 . The logic puzzle of  claim 1 , wherein the indicia comprises text in one or more languages. 
     
     
         6 . The logic puzzle of  claim 1 , wherein the indicia comprises numbers in one or more arithmetic formats. 
     
     
         7 . The logic puzzle of  claim 1 , wherein the indicia comprises a pictorial or symbolic image. 
     
     
         8 . The logic puzzle of  claim 1 , wherein the indicia form Venn Diagrams. 
     
     
         9 . The logic puzzle of  claim 1 , wherein the indicia is three-dimensional. 
     
     
         10 . The logic puzzle of  claim 1 , wherein the indicia comprises Braille script. 
     
     
         11 . The logic puzzle of  claim 1 , wherein the plurality of indicia comprises elevations and ridges forming a three-dimensional maze. 
     
     
         12 . The logic puzzle of  claim 1 , wherein the first geometric solid comprises at least three rotatable layers along each axis. 
     
     
         13 . The logic puzzle of  claim 1 , wherein the geometric solid has a shape that is one of: cube, tetrahedron and dodecahedron. 
     
     
         14 . A logic puzzle comprising:
 a first geometric solid having a first predetermined number of visible outer faces, the first geometric solid comprising a plurality of second geometric solids, the plurality of second geometric solids each having a second predetermined number of visible outer surfaces;   the second geometric solids each being rotatable within the first geometric solid such that at least one visible outer surface of each second geometric solid comprises a portion of one of the faces of the first geometric solid for at least one rotatable orientation of the plurality of second geometric solids within the first geometric solid; and   at least one sticker disposed on the at least one visible outer surface of the second geometric solid,   wherein a pattern is created by a plurality of stickers, and each of the stickers are coupled to a sticker on another surface.   
     
     
         15 . The logic puzzle of  claim 1 , wherein a sticker of the at least one sticker has a desired orientation that stays true after any numbers of moves/rotations of the layers of the first large geometric solid. 
     
     
         16 . The logic puzzle of  claim 1 , wherein a meaningful expression is created by a collection of the stickers. 
     
     
         17 . The logic puzzle of  claim 1 , wherein the sticker comprises text in one or more languages. 
     
     
         18 . The logic puzzle of  claim 1 , wherein the sticker comprises numbers in one or more arithmetic formats. 
     
     
         19 . The logic puzzle of  claim 1 , wherein the sticker comprises a pictorial or symbolic image. 
     
     
         20 . The logic puzzle of  claim 1 , wherein the sticker form Venn Diagrams.
