Abstract

The invention provides a puzzle embodied in a 3-sided regularly shaped pyramid comprising eleven smaller 3-sided pyramids and four small octaeder shaped bodies, which smaller pieces are connected to a string forming an endless chain. The complexity of the puzzle is achieved by coloring the side planes of the smaller parts in various colors and connecting the smaller pieces in a certain sequence to a string. The solution of the puzzle is obtained by placing the smaller parts of puzzle in such a way that the large pyramid is formed and the side planes of the large pyramid are uniformly colored by the smaller pieces. A preferred embodiment is given in FIGS. 1 and 2 comprising the 15 smaller pieces of FIGS. 3 and 4 placed in a continuous string as shown in FIG. 5.

Dependent claims

A 3-dimensional, geometric puzzle comprising:

eleven tetrahedral pieces, each identical to one another in shape and dimension and each having a shape and a plurality of edges conforming to a regular tetrahedron having surface planes, each of said plurality of edges being of a first length;
four octaeder pieces, each identical to one another in shape and dimension and each having a shape and a plurality of edges conforming to a regular octagon having surface planes, each of said plurality of edges being of said first length;
and,
means for connecting said tetrahedral pieces and said octaeder pieces in a specified sequence in a strand, said pieces are distanced from one another in said strand to permit orienting of said pieces relative to one another to form a 15-member structure having, in its assembled state, a plurality of edges and a shape conforming to a regular tetrahedron having surfaces, each of said plurality of edges of said 15-member structure being of a second length, said second length being substantially equal to three times the length of said first length.
