Abstract:
A three-dimensional puzzle is composed of, for example, 4n (n is a given natural number) puzzle pieces (51 to 54) each having a tetrahedron, formed into a first-order approximation Sierpinski tetrahedron when correctly connected, and showing two images. Fragments (PA1U to PA4U·PA1D to PD4D) of a first image (PA) are formed on two faces of each of the puzzle pieces (51 to 54), and fragments (PB1L to PB4L·PB1R to PB4R) of a second image (PB) are formed on the other two faces. Magnets (51a to 54a·51b to 54b) are so buried that two vertexes are N poles and the other are S poles. With this, a three-dimensional puzzle which is so difficult to require ability of imaging a solid figure, rewarding, as a tool for fostering the ability of imaging a solid figure, and useful as a decorative article or an advertisement exhibit when completed is provided.
