This is the third version of Juno’s grooved 6 board burr series puzzle which requires 34 insane moves to remove the first piece from the assembled shape. The difficulty of the puzzle is extreme and even disassembling is quite challenging. You can easily be disoriented and lose the idea whether you are assembling the puzzle or disassembling.

Puzzle solving computer program BurrTools says that it has 1676 assemblies and a unique level 34-9-9-6-2 solution but there is at least one shortcut solution to remove the second piece from the assembled shape using a rotational movement. Thus, we simply say that it is a level 34 burr. #1 was level 22 and #2 was a relatively easy level 25, so these numbers will indicate to you how tough #3 would be.

Our original plywood of New Guinea Walnut and European Beech is used for the main part of the puzzle and its white eight teeth that are hidden when the puzzle is assembled are made of Silver Ash. It was a bit challenging to produce the puzzle pieces because they have grooves on the side. Concave for the teeth parts were also having to be shaped out by a CNC router not to lose decent accuracy. The puzzle required time-consuming work and we produced more numbers than #1 and #2 to keep the retail price the same as the former series.

The puzzle is sold assembled. The solution to this puzzle will be supplied upon request by Burr Tools file format.
