A maze has two opposing substantially coextensive walls one of which forms an inner three-dimensional form or shell and the other which forms an outer form or shell. Each of the shells is generally in the form of a cube and the inner shell is fixedly positioned within the outer shell so as to maintain a predetermined, uniform distance between the inner and outer walls. The outer wall is formed with a network of channels which, together with the inner wall, define a corresponding network of passageways. The passageways on each side of the outer cube are connected to the passageways on the adjacent sides of the cube so as to form interconnected passageways which permit one or more marbles, for example, to move through the passageways on one or more sides of the cube with changes in orientation of the maze in space. Apertures are provided in at least one passageway on each side of the cube for providing points of entry and exit for the marbles into and out of the maze. By selective changes in orientation of the maze in space marbles within the maze can be made to move through the passageways without escaping through the apertures.
