Pedagogical, educational and educational game, of the type constituted by reliable parts, characterized because this constituted by six oblong pieces coupling between themselves to form a spherical body, of whose six pieces exist three equals (3), which are the basis of the construction, two equal (3) that complement with the previous and a last piece (1) that constitutes a closing type pin of the sphere assembly, presenting these parts the following configuration: a) the piece (1) is constituted by the intersection of a sphere with a prism of rectangular section that presents one of its diagonals coincidente with the radio of said sphere. B) the piece (2) is constituted by the intersection of a sphere with a prism of rectangular section, which presents one of its diagonals coinciding with the radio of such sphere and that, in its time, presents two emptied in quadrant in the diedro opposite to the surface curve of the piece that defines a pyramid of square base, coincidental with the diagonal plane ortogonal to the radio of the sphere; c) the piece (3) is constituted by the intersection of a sphere with a prism of rectangular section, which presents one of its diagonals coinciding with the radio of said sphere and that, in its time, presents two emptied in quadrant in the diedro opposite to the surface curve of the piece, that define a pyramid of square base, coincident with the diagonal plane ortogonal to the radio of the sphere, and a third emptied in quadrant coincident with one of the side sectors of said pyramid.
