PROBLEM TO BE SOLVED: To provide a puzzle of assembling single solid blocks to form a shape of a soccer ball (sheared regular icosahedron) (FIG. 3) and the like such that patterns and magnetic poles match with each other at junctions, respectively. SOLUTION: Sheared regular tetrahedron building blocks (1) each having two pairs of magnetic poles (a solid composed of four regular hexagons and four regular triangles) are used to constitute an icosahedron (soccer ball shape) and the like. The regular hexagons (2) of the building blocks (1)are provided with patterns at the surfaces thereof to forming the puzzle.
