<p>Jigsaw cube comprises the outer cage (1) in the shape of a prism, inside which cubicles (2) are arranged in a sliding way, while the cage (1) has openings (3) in its walls to shift and hold separate cubicles (2), whereas the number m of the cubicles (2) arranged in sliding way is given by the relation: m = a.b.c-1 where a, b and c, which can be the same or different and represent an integral higher than 1, indicating a number of openings (3) per row in the wall at three various edges of the prism crossing in one point. Separate wall of internal cubicles (2), margins (5) of openings (3) of individual walls and/or separate walls of the cage (1) are of a different colouring, while separate walls of inner cubicles (2) in the arranged condition have the same colour as the appropriate margin (5) of the opening (3) and/or an appropriate wall of the outer cage.</p> |
