About this monstrous puzzle:
This is the three-dimensional spherical labyrinth that challenges the limits of your manual dexterity and spatial understanding as you maneuver a 5/8" wooden marble through its entire course. The Superplexus is a complex network of chicanes, multi-planar hairpin turns, spirals, and staircases--even a vortex. Hand made from 3- and 6-ply Finnish birch that form the track, over 400 hours are involved in its construction. The labyrinth is set inside a 36" diameter acrylic sphere affixed to a Jatoba base using a stainless steel gimbaled mount that allows you to tilt the sphere in any direction to guide the marble.

If you're short on cash (or the sweater vest) you could consider the regular Perplexus Maze Game for a mere $22.
