Quadlock I & Burrlephant 3

Jerry McFarland

By now, you may have heard about the awesomeness that is Jerry McFarland’s Fidget Burr (you can check out my review here); since enjoying the pleasure of solving Fidget Burr, I have had the good fortune of obtaining and solving two more of Jerry’s puzzles: the older Quadlock I and the quite new Burrlephant 3. Both are excellent puzzles, offering unique takes on burrs by adding take-apart / trick box-type elements to the mix, with perhaps a dash of sequential discovery.

Quadlock 1

Quadlock 1 is a squashed cube made of 19 individual burr sticks, originally made by Jerry in 1992, and remade in 2008 and 2011 (possibly again since then). It is a 4 x 4 x 3 “cube” that measures 3.5″ x 2.6″ (after 2011, Jerry began making a slightly smaller version). It is made of Walnut, Mahogany, and Maple, although there are some versions made of alternate, exotic woods, as well. I have two copies of this excellent and quite challenging puzzle, which only goes to show that I truly think it is a great puzzle: they are both copies of the earlier, larger versions (one has the serial number “14 JM 94” and the other copy has “10 JM 92” – I am not certain if this means that they are from 1994 and 1992 but I will update once I ask Jerry about it).

If you have solved interlocking puzzles, you will know that many feature some sort of key piece, which must be discovered and moved before you can hope to progress. Quadlock 1 takes this a few steps further, with four pieces that work together to form a lock, preventing any further movement. After fumbling for some time, I found that it is better to approach this almost as I would an attempt at lock-picking, as I was better able to conceptualize how I might find my way past. As you are working on these early steps, you have no indication of what it might lead to: the other pieces permit no movement, whatsoever, forcing you to add some tension in various places as you struggle to find the correct movements and configuration of the four locking pieces (again, as one might a lock). You are unlikely to succeed early on without some amount of close observation, finding the correct moves step by step rather than all at once. It has only been a few weeks since I solved the puzzle for the second time, and I am already confused as to how I can repeat the process, showing the puzzle’s excellent replayability.

Once you find your way past this first wall, you are rewarded with some interesting movements, opening the puzzle up enough to permit the removal of some pieces. You are not done, of course, as you must now discover steps necessary to fully disassemble the puzzle, although you have now successfully navigated the main challenge. From this point, you will still need to think and explore as some of the next steps are certainly non-trivial, albeit perhaps not as difficult as the opening sequence of moves. Having found these next steps, the puzzle comes apart in a way that is conceptually similar to Fidget Burr, while consisting of totally different arrangements; at this point, disassembling it completely is pretty straightforward, leaving you with a nice pile of lumber.

My first time through, I chose to let the pieces sit for a day or two before returning to it for reassembly. I was able to reassemble the puzzle (mostly) without the assistance of burrtools or the instructions Jerry provided with the puzzle. His instructions are quite welcome, as they provide clear assistance without actually showing you specific the moves (as with burrtools); it will tell you which pieces need to be manipulated but leave it to you to find how this must be done (which at times is certainly not totally straightforward).

There were a couple particularly tricky aspects to reassembly – the main locks were actually not so difficult in reverse, but I found a couple steps midway that had me turned around, requiring more than a little Ikea-style mid-process disassembly; the pieces have enough non-uniformity to create the need for careful observation lest you find yourself painted into a corner.

I found this puzzle to be an excellent interlocking burr cube (squashed or otherwise) – the addition of a “trick” locking mechanism making it especially fun. I hope to eventually collect Quadlocks III and IV (II was essentially a 23-piece version of I, and very few copies were made, so my completist urges are that much more likely to go unfulfilled).

Burrlephant 3

I am clearly a fan of Jerry’s work – I have pieces he made for Bill Cutler that show his skills as a craftsman, and his own designs blow me away. Burrlephant 3 is another example of Jerry’s ingenuity as a puzzle designer, with multiple trick phases belying its playful exterior. First off, it is important to distinguish this from Don Closterman’s Elephant puzzle; I’ve not done that puzzle, but it appears to be a kumiki-like 3D assembly, and, as such, is nothing like Burrlephant in anything other than a cursory look at its appearance. Closterman’s Elephant could be an amazing puzzle, I’ve no idea, but I am mostly sure that it does not contain the mechanics of Jerry’s that separates his puzzles from most interlocking burrs.

Burrlephant 3, in case you’ve not noticed, looks like an Elephant, complete with trunk, tusks, eyes, and big ole ears. It is an interlocking figure, comprised of 27 interlocking pieces of Jatoba, Bloodwood, Bubinga, and Ebony, as well as a few additional magnets and metal pins. Not counting its ears or tusks, it is a sizable 4.4″ x 5.5″ x 2.2″, making it significantly larger than Quadlock 1 or Fidget Burr.

When I started working on it, I quickly found that there looks like there is at least one aspect that appears similar to Fidget Burr, which a halfway close inspection of the photos will show; however, the mechanisms are not at all similar: Fidget Burr has an easily accessible button that leads to instant action, whereas Burrlephant requires much more exploration to make any sort of progress. You are able to find some movement quickly, but this does not appear to do anything helpful.

Burrlephant 3 essentially consists of 4 challenges, some requiring several steps to complete. Only after solving the fourth challenge, which rewards you with the key piece containing the serial number, are you are able to fully disassemble the puzzle into its 29 distinct parts. The puzzle succeeded at misdirecting my focus for some time, before I was able to fall upon the first challenge, decidedly the easiest of the four as trial and error will most likely get you there before too long. The second challenge requires some thought, and develops a better understanding of certain aspects of the puzzle, before leaving you with a few pieces in your hands and no idea how to proceed.

This third challenge is my favorite and is the one on which I spent the most time (mostly doing the same few things over and over while incredulously shaking my head and wondering it it was broken – spoiler: it wasn’t). You must first use what you know about the puzzle to determine what needs to happen next before you can hope to do anything else. Once you have considered the what, the how is going to take even more thought; trial and error will help to eliminate your options, but I found I was only able to find my way through by engaging in some good old critical thinking. Having found the solution, I am impressed by how simple and elegant it is to do despite having been so difficult to figure out. This part of the puzzle is pretty ingenious and relies on some precise designing and craftsmanship to accomplish. I actually repeated the step a few times, just because it made me happy – always a sign of a good puzzle.

At this point, it is fairly clear what you need to do for the fourth challenge; accomplishing this task is a bit tricky, and I was able to figure it out before too long, some trial and error pointing me in the right direction and leading me to the removal of the key piece. Having removed most of the tricky parts of the puzzle in overcoming the various challenges, complete disassembly is now fairly straightforward.

The puzzle comes with Jerry’s description and solution, in text and pictures, and Jerry has again labelled some of the pieces to aid in reassembly; he stepped it up a bit from Fidget Burr, etching them into a few pieces that could easily get mixed up otherwise. Sitting back and looking at the rather enormous spread of pieces before me, I nonetheless felt confident that I would be able to reassemble it without too much frustration; there is one part that is a bit tricky, due to the necessary placement of some magnets, but a bit of dexterity gets me through, allowing me to return to reassembling the main challenges of the puzzle.

Overall, Burrlephant 3 is an excellent and super-fun burr puzzle with elements of sequential discovery and take-apart trickery that earns it the right to stand apart from other puzzles, unique in its cross-genre design and its slick and playful appearance. In many ways I prefer its quiet, contemplative rhythm to Fidget Burr’s in-your-face action; either way, it is just another example of Jerry’s craftsman-informed ingenuousness, which has me craving his next creation.
