Four Cubes by Cubic Dissection

"Four Cubes is Kohno Ichiro's follow-up to the brilliant Three Cubes puzzle. This sequel puzzle features two pairs of identically shaped pieces embedded with magnets similar to Three Cubes. The goal is to combine the elements to create a stable assembly forming four distinct, equal-sized cubes, each connected to the neighboring cube with no more than a half-face. Despite having two possible solutions, Four Cubes is a step up in difficulty. A secondary challenge is possible: find a solution that creates two bars of equal length.

Once solved, the puzzle snaps into shape, resulting in a beautiful and entertaining fidget toy. Four Cubes belong to a set, including the Three Cubes and Five Cubes puzzles. Each escalates in difficulty.

This batch of Four Cubes was constructed from nicely figured Bubinga lumber. Approximately 65 copies of are available. Four Cubes ships in an unsolved configuration."
