Squary Packs, Quadro, Snake Pit, Mushkila

Yavuz Demirhan (check out his Etsy store)

In case you haven’t noticed, there are a lot of puzzles out there. A lot. Within the various subgenres of mechanical puzzle-dom, therein lies nearly infinite possibilities – who would have thought that even “just” a 4×4 cube could contain so many possibilities as to continuously bring us more TICs and Somas and so on…

Squary Packs

Some puzzles push out into their own territory, their movements and solution sitting somewhere amidst or between those that already exist. Yavuz Demirhan’s Squary Pack series is a great example of such a design: they are 2D/3D packing sliders that require you to navigate four dual-leveled pieces through a restricted one-piece-size opening at the center of the space to cover the bottom of the square box. The pieces are all flat-bottomed, with various voxels of different dimensions further complicating the solution, requiring you to slide your pieces around as you attempt to find a way to insert whichever piece needs to go in last; some of the series are further encumbered by blocks affixed to the box. You need to get all pieces in with the blocks facing up and you will find varying degrees of difficulty identifying where and when in the dance of pieces you can insert the final pieces.

The result can be quite tricky and is most definitely fun. I initially got #2 and 4 (knowing as I did that I would almost certainly end up wishing I had just gotten them all – my recent delivery of #1, 5, 7, and 8 shows I was most definitely right in thinking I had been wrong). My first impression was that they are quite attractive looking puzzles: his work is always wonderful looking and these are no exception. Dark wenge boxes with a reddish sappeli for those with blocks attached, which cover one of the two levels and protrude above the acrylic top for half that height. The pieces match the boxes with the same wenge contrasted by light ash blocks atop them. On the bottom of the box he has his logo/initials engraved above the name and # of the puzzle. Interestingly, they range considerably in the square’s dimensions (while all sharing a height of 3.5 cm): 1 & 2 are 7.5 cm, 3-5 are 9.5 cm, 6 is 11.5 cm, and 7 & 8 are 13.5 cm (ranging in price for a reasonable $30 – $50 depending on size). I’m happy to say that Yavuz is designing additional Packs, extending the series to (at least, I believe) 15.

Sitting down with the Packs, it took a minute to orient myself to what exactly I needed to do – initially, I solved my first two incorrectly by placing one of the pieces upside down (which was itself a non-trivial solve). I later learned that this was not correct and proceeded to attempt to (re)solve them correctly. It is necessary to find a way to get three of the pieces into the Pack such that there remains room for the 4th to be inserted and slid into the existing space – oftentimes requiring that the remaining pieces dance around before this becomes possible. This is complicated further in those Packs that contain internal pieces blocking the way. Each solution is unique and while these puzzles share a pleasantly consistent aesthetic, they are quite diverse. They range in difficulty: all the feedback I have heard from our fellow puzzlers has been most definitely positive, although some have felt that a couple of them were a bit easy. Regardless, I found them all to be challenging, with some being quite difficult (particularly #2 & 4). The coming versions are apparently a further step up in difficulty, and I look forward to getting them once available.

Yavuz has been making puzzles for a while and has a LOT more interlocking and packing puzzle designs out there (he has a few hundred on PWBP); while he produces his own works from time to time, it is not at all uncommon to find his works included in the puzzle releases of others (including one design set to come out in this week’s CubicDissection release). While I have a few of his designs that were made by other puzzle-makers, I also have the pleasure of owning a few more that he made himself – also 3D packing puzzles with restricted openings. His work is all wonderfully precise, using quality woods that look and feel great.

Quadro

Quadro is a small-ish puzzle whose wooden box and acrylic top share an aesthetic with the Squary Packs (the puzzle’s name also etched into the bottom). It consists of 6 identical squares that must fill a rectangular box – while not interlocking, the solution will require a rather delicate dance to allow you the chance to drop that last block in with the satisfaction the comes with finally filling this up with those. This is one of those puzzles that is more complicated than it looks without being something insurmountable – I still managed to go in circles for quite a while, even asking other puzzlers if perhaps there was a “trick” that I was missing. Eventually I actually stopped and tried that thinking thing I’ve heard so much about, soon managing to find the right moves (leaving me wondering how I had managed to do everything but the one thing that would work).

Snake Pit

Snake Pit eschews the acrylic top for an attractive mix of light and dark woods with an opening that runs the length of the puzzle and is 1/2 as wide, leaving one voxel on either side. There are 4 pairs of mirrored pieces that must find their way inside for a fun solution that was just the right level of difficulty for me.

Mushkila

Mushkila is my newest acquisition, having received it along with my second order of Squary Packs. It uses a beautiful mix of woods with lovely grain patterns that play nicely with the mix of red and dark and light brown. Interestingly, the opening is not a regular shape: it runs the length of the box (similar to Snake Pit) to allow the single rectangular piece to go in and also adds a square cut-out to allow the five angled pieces to go in at any orientation. This gives it a bit of a deco look, which meshes well with his choice of woods. I have yet to solve it, but having spent a little bit of time on it, it is clearly a non-trivial solution that should provide a fun solve while looking great on my shelf.

All of these packing puzzles share a simplicity and elegance, both in terms of their aesthetic as well as their movement – I highly recommend following Yavuz’s Etsy page as I know that any time Yavuz has something available, I will happily say “yes, please” to whatever it is, sight unseen

Anti-Gravity Box

Frederic Boucher, 3D Packing Puzzle, 2.25″ x 2.25″ x 1.5″

A few months ago, I wrote to Frederic in the hopes that he might happen to have a few puzzles that were seemingly unavailable. Most were, but he did happen to have a last copy of Anti-Gravity Box, which I happily requested, along with a few other new puzzles that he had on hand.

I have solved several of Frederic’s puzzles in the past – 3D and 2D packing puzzles that offer a serious challenge, comparable to pieces by MINE or Osanori Yamamoto, featuring elements such as interlocking elements and restricted openings.

Anti-Gravity, however, adds new mechanics by introducing a number of magnets into the mix. This makes for a unique and novel puzzling experience; it is no longer “just” about finding a way to get the pieces into their frame, as the magnets throw one’s general approach out the window.

The box is a 3×2 voxel frame that features a removable, acrylic top, allowing you to easily reset the puzzle and view your progress. The box has two, single voxel openings at 90 degrees to one another; both are in the middle of the bottom level, allowing you to enter each axis, but offering no room for angles of any kind. You must fill it with 6 identical rectangular 3×1 blocks; 2 have two magnets on one side, 3 have magnets on one end, and one block has none.

There are rules, of course: you need to place it on a flat surface and you are not meant to pick it up or tilt it (of course, you may hold it while you insert other pieces); you cannot poke your finger into either of the openings to push the pieces; it goes without saying that you cannot just lift off the top and place them in. The removable top is a kind addition, as it avoids the need to struggle to remove pieces when you have eventually found you had made a mistake. The puzzle arrived with the pieces stacked neatly inside. It is kind of cool to have a puzzle so confident in its structure, that it can come fully solved without having spoiled anything.

While by no means simple, neither is it an overly difficult puzzle – in my experience, one of his other packing puzzles was more challenge than I could meet (I am admittedly not so great at packing or interlocking puzzles generally – my interest far exceeds my ability when it comes to these types of puzzles).

More importantly, this is a very fun puzzle, and one with which trial and error will not get you very far; knowing the pieces you can eventually figure your way through it.. After spending a few minutes playing with it, experimenting to get to know the pieces and what they can and can’t easily do, I had to stop and think. This led to the first big aha moment of a series of such moments, leading to the full solution. Each step is its own planned approach, each piece requires forethought once a workable order has been determined. Apparently, this has two approaches that lead to similar solutions; I have found one and will undoubtedly spend some more time to find the second.

TL;DR: Anti-Gravity Box by Frederic Boucher is an original approach to a 3D packing puzzle, with magnetic pieces needing to be stacked using entries that allow for little margin of error. While not Boucher’s hardest puzzle, each move must be planned and purposeful through thoughtful approach and not just trial and error. It features a convenient removable top to reset after you inevitably make a mistake, and is so confident in its own puzzling, that it can arrive solved without lessening its challenge.

Packing It In 2: Pack Harder

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.

Packing It In: Pack Hard

I’m sure they’ll all go right back in – yeah, sure they will….

First off, I’ve decided to dispense with some of the bells and whistles to my posts, as I’ve found it prevents me from sitting down and writing. And I know my one (imaginary) follower is just salivating for more of my puzzling narratives.

Recently I began exploring packing puzzles; as one who had come to puzzles with a fascination with boxes and locks, the elusive, hidden “trick” being the main attraction, packing initially seemed a bit…. meh.

Once again, I was quite wrong! I began with Baumegger’s Gretel, quickly becoming disappointed I had not also bought her brother at the same time. First off, it is a truly lovely puzzle. The various woods are smooth and the colors play wonderfully with one another. Perhaps my favorite detail is the tiny nub at the top that secures the clear, acrylic cover (assuming you can solve it of course).

Stephen was easy to contact and talk with, and the puzzle arrived soon. For such a small, straightforward task, this thing was HARD. Maybe it is the ancient Tetris player within, but I took to it immediately. Solving it would take much longer, and in the meantime I would go on to collect several more packing puzzles.

Eventually, it just…. worked. Such satisfaction. I gleefully showed my wife, who glanced briefly over (“that’s nice, babe”), before returning her attention to the show I’d forgotten we were way supposed to be watching. My focus was all on my perfectly packed puzzle, grinning proudly (me, not the puzzle). My little cover slipped on, perfectly held in place, and off she went to join my small collection of solved packing puzzles.

Fast forward a couple weeks, and I was taking a pic to show a fellow puzzler how pretty she is: hold on…. I can’t take the pic of it solved lest too much be revealed. I’ll just dump it out; surely I can repack it, no prob.

Yes, it remains unsolved. Yes, I swear it was packed. Yes, she got moved back to her evil, unfriendly and unsolved cousins. Maybe she’s mad I didnt get her brother? Well, guess I have no choice. What’s one more puzzle? Right, it’s just one. One never hurt…… Sigh……
