Abstract: An educational game having a number of parts where each part has a contact surface with first and second magnets movably joined to and interior face of the contact surface. A rod that defines a longitudinal axis parallel to the contact surface has the first magnet at one end and a second magnet at the opposite end, with the magnets having their polarity reversed to each other. An elongated housing encloses the rod on the interior face of the contact surface, and it moves the rod on the longitudinal axis along the housing.

Abstract: Puzzle formed by a plurality of cubes. Puzzle formed by a plurality of cubes, wherein each face (3) of each cube shows a fragment of an image, and which is formed by a quantity of cubes whose square root is a whole number. The cubes may be arranged three-dimensionally forming a bigger cube in such a way that each of the faces of the bigger cube shows an image formed by the fragments of images of each of the seen faces (3) of each of the cubes. Each of the cubes can have reversible connecting means for connecting the cube with cubes adjacent thereto preferably by means of movable magnets. The puzzle can be used as a flags construction game.

Abstract: Didactic game piece that has a contact surface (3) and contains at least a first magnet (5) with its magnetic axis facing towards the contact surface (3), in which the first magnet (5) is connected to the piece in such a way that it is possible to shift the magnetic axis with respect to the contact surface (3), such that any contact surface of any piece may face any contact surface of any other piece, the two contact surfaces being connected through the action of the attraction forces of the respective magnets. The didactic game comprises a plurality of such pieces and may be a cube puzzle formed by a plurality of cubes in which each of the cubes is a piece according to the invention.
