Closed Box (black)

by Christoph Lohe

It measures 60 mm x 60 mm x 60 mm.

We used Wenge and Maple in the process of making this puzzle.

The difficulty is move: 23 (15.6.2).

Christoph Lohe wrote about it:

“With just three sticks of length five, densely packed into a cubic frame, the Closed Box is not the most difficult puzzle, but all but trivial to solve. It requires 15 moves to release the first stick, and it displays nicely with six closed sides. I am very happy to see it made in a high-quality Deluxe version with outstanding wood craftsmanship.”
