Abstract:
A maze structure including:an end level comprising: a first end surface; a plurality of exterior walls extending outwardly in a generally perpendicular direction from the first end surface of the end level adjacent a periphery of the first end surface defining a perimeter of the end level; a plurality of interior walls extending outwardly in the generally perpendicular direction from the first end surface of the end level within the perimeter defined by the exterior walls of the end level, the interior walls dividing the end level into a plurality of chambers; and a second end opposite the first end surface which is at least partially open; at least one stacking level comprising: a first end surface: a plurality of exterior walls extending outwardly in a generally perpendicular direction from the first end surface of the stacking level adjacent a periphery of the first end surface defining a perimeter of the stacking level; a plurality of interior walls extending outwardly in the generally perpendicular direction from the first end surface of the stacking level within the perimeter defined by the exterior walls of the stacking level, the interior walls dividing the stacking level into a plurality of chambers; and a second end opposite the first end surface which is at least partially open; the first end surface of the stacking level including a plurality of apertures therein, each being arranged to communicate between one of the chambers of the stacking level and one of the chambers of a level supported adjacent thereto through the at least partially open second end of said level supported adjacent thereto; said at least one stacking level being arranged to be supported on top of the end level with said at least one stacking level being arranged to be supported on an adjacent one of the levels in a plurality of relative stacking orientations therebetween with each of the apertures in the first end surface of said at least one stacking level being arranged to communicate with one of the chambers of said adjacent one of the levels through the at least partially open second end of said adjacent one of the levels in each of the plurality of stacking orientations; the end surface of each level comprising a plurality of interconnected modular units which are selectively separable from one another, each modular unit having an end surface with side edges and at least one wall extending outwardly in the generally perpendicular direction from a respective one of the side edges thereof, each of the walls of the respective modular units forming part of the interior and exterior walls of the level.
