<p>Construction game of three-dimensional geometric structures based on a plurality of plates of a certain thickness which take the shape of a regular polygon with an even number of sides, preferably hexagonal or square. Said plates are characterised in that they have positive joins in half of the consecutive sides and negative joins in the other half, the positive and negative joins are complementary and are used for joining two parts to form an arbitrary dihedral angle. The parts are also equipped with a fit used for joining two of them parallel to their planes. The special arrangement of the positive and negative joins on both sides of the part, where all those of the same type are consecutive, affords great flexibility to the system. The joins are symmetrical with respect to a plane perpendicular to the plane of the part which passes through the perpendicular bisector of the face in which it is situated.</p> |
