Description
Equa – Advanced Take Apart Puzzle
Equa is a cast-metal take apart puzzle designed by Oskar van Deventer and produced by Hanayama. A planet-like center sits tightly inside an enclosing ring, giving the puzzle the appearance of an astronomical model.
Discover how to remove the central form from its surrounding ring, then put it back together. At first the center appears able only to rotate on its axis; the challenge is to understand what the geometry permits beyond that first impression.

Features:

Why You'll Enjoy It:
