While Gretel remained unsolved (the first time), I became aware of how many excellent packing puzzles there are out there – and, unsurprisingly, Cubic Dissection held several excellent examples of my newfound delight.

I decided to take a few steps back, opting for a couple “easier” packers; mostly, I think, so I could show myself that, yes, I am actually capable of putting things into something else.

Pin Block Case is wonderfully made, as one would expect from anything from CubicDissection, with perfect dimensions that allow its pieces to juuuuust fit. True, it is not perhaps as challenging as some of its noteworthy cousins, but it does not change the fact that the solution is elegant and satisfying. Designed by Hajime Katsumoto, CubicDissection had released it as a part of their (unfortunately discontinued) Artisan series.

It is a pretty straightforward puzzle: 4 blocks with small metal pins on one side and a slot running down another must fit into a cube with one corner open. This is made much more difficult by the fact that the slots do not run the length of the block; the perfect fit into the cube creates a challenge in fitting them in despite the pins’ best efforts to the contrary.

I think that this is an excellent introduction to packing puzzles, and to wood puzzling generally; it shows how something that seems simple is not necessarily easy. What’s more, trial and error may help you to see what not to do, but the solution is best found by stepping back and, well, thinking.

Suddenly, the necessary angles and orders became clear, and they slipped in perfectly and elegantly, as though I should have known all along that is how they were meant to go. And an excellent final detail: unlike many packing puzzles, Pin Block may be displayed and shared solved without spoiling anything – all one sees are 4, apparently plain, same-sized blocks resting comfortably behind the quarter cut hole. Removing them offers the same challenge in reverse, although it should of course first be approached unsolved, as with packing puzzles generally.

Not being the most difficult puzzle is an attribute of this lovely piece; the satisfaction of the graceful solve is not lost in such relative simplicity, quickly adding packing puzzles to my addiction while putting a happily stupid grin on my face.
