A cubical maze module, counterintuitive in operation, consisting of a hollow cubical box having six transparent walls with eight circular openings of the same diameter; the walls defining four tortuous conduits, each extending from and between a circular opening, eccentrically located, in the center of one quadrant of a wall, and a circular opening, eccentrically located, in the center of one quadrant of an adjacent wall; the tortuous conduits forming passageways for a ball. No matter which side is up, on a horizontal surface, the ball is always able to traverse a plurality of tortuous conduits, under gravity, while not able to traverse one or two other tortuous conduits, as the module is manipulated about the three-dimensional axes. A cubical maze module can be used singly, or as a plurality of identical cubical maze modules which are interchangeable; with each additional module the tortuous conduits can be linked to allow passage of the ball through progressively longer and exponentially more complex combinations of paths; it is possible for up to four paths to cross within one cubical maze module.
