Most of my designs are named No Name, blank, space, or whatever your favorite term is for an unfilled spreadsheet cell used to contain a puzzle’s name. It seems that my creativity process shuts down after the puzzle design is complete. My first few puzzle designs were lucky to have been named by my wife (Eviction, Confusion, Secret Garden, The Couch, The Maze). Some later puzzles were named after the wood used to make them by the craftsmen who made them as a way to identify them (Pink Ivory Ring, Multiwood). Even others were named for their warm reception by the puzzle community (Reject #1, Reject #2, Reject #3). I completely empathize with puzzlers that collect puzzles with no names. Around our house, we refer to Yunichi’s new puzzle as Yukari’s Cube.
|The Little Present|
Since Yukari didn’t provide a picture of the puzzle in the solved state, I wasn’t sure if the cube was solid (easier), had holes (more difficult), required odd angles (even more difficult), or was a completely cosmic cubic space created by an insanely convoluted wooden shell (who comes up with these crazy ideas kind of difficulty). I didn’t even know if you could make a cube with 9 corner pieces before all the angled cuts are added. The 9 corner pieces are made with 27 cubes, the same as a 3x3x3 cube, which is a good first indicated that it might be possible. I decided to test that out first. I found out that … well you should figure that out for yourself. I’d hate to be the despoiler of frustration (i.e., fun).
My 5 year old grandson, not one to be constrained by complex geometric shapes like cubes, set out to design his own solution and built an abstract pagoda. We even built a little present complete with bow.
Yukari was right in pointing out that many puzzlers will be able to solve this relatively quickly. Yukari alluded to a little trick, but from my perspective, I think that there are 2 that you need to overcome. Unfortunately, I can’t mention them here without spoilers. It took me about 10 minutes to construct the cube, which included the time spent on deciding what the cube looked like. However, I half expect someone to eventually tell me one day, “That’s not the solution”.
Yukari included the sad disclaimer that there is no plan to produce this puzzle but I wouldn’t be surprised if Yunichi had some puzzling tricks up his sleeve to add to this puzzle. Maybe someday it will become one of Yunichi’s groovy puzzles or the core of a grander undertaking. Keep your eye on the Pluredro shop.
