In one embodiment two or more maze units are stacked, one on top of the other, with aligned exit and entry holes so that a ball or marble that successfully traverses an upper unit falls into an entry point of a lower unit. In another aspect two or more maze units are interconnected end-to-end on the same level. Methods are disclosed for the use of such mazes in a variety of didactive scenarios.
