Multi-functional pyramid sphere-puzzle system

Abstract

A multi-functional pyramid sphere-puzzle system includes five types of basic sphere pieces. The basic sphere pieces comprise one three-sphere piece and four different four-sphere pieces. The three-sphere piece has a 120-angled array. The first four-sphere piece is arranged in a vaulted array, the second four-sphere piece in a first three-sphere linear array, the third four-sphere piece in a second three-sphere linear array, and the fourth sphere piece in a right-angled array. In puzzle game, the selected types and the desired amount of the sphere pieces can be assembled to form the pyramidal array with various orders.

1 . A multi-functional pyramid sphere-puzzle system, comprising: 
 a plurality of three-sphere pieces each having three identical sphere units defining a single type of a three-sphere array adapted to fit for a triangle-based pyramidal array; and    a plurality of four-sphere pieces each having four identical sphere units defining at least one type of a four-sphere array adapted to fit for the triangle-based pyramidal array;    wherein the selected types and the desired amount of the three-sphere pieces and the four-sphere pieces can be assembled to form the triangle-based pyramidal array with various orders.    
   
   
       2 . The multi-functional pyramid sphere-puzzle system as defined in  claim 1 , wherein the three-sphere array of the three-sphere piece defines an angled array.  
   
   
       3 . The multi-functional pyramid sphere-puzzle system as defined in  claim 2 , wherein the angled array of the three-sphere piece has an included angle of 120 degrees.  
   
   
       4 . The multi-functional pyramid sphere-puzzle system as defined in  claim 1 , wherein the four-sphere arrays of the four-sphere pieces are selected from a group including a vaulted array and a first three-sphere linear array.  
   
   
       5 . The multi-functional pyramid sphere-puzzle system as defined in  claim 4 , wherein the group further includes a second three-sphere linear array and a right-angled array.  
   
   
       6 . The multi-functional pyramid sphere-puzzle system as defined in  claim 1 , wherein the fourth order of the triangle-based pyramidal array can be constructed by the four-sphere arrays of the four-sphere pieces consisting of a vaulted array, a first three-sphere linear array, a second three-sphere linear array and a right-angled array.
