Grooved 6 Board Burr #4 – Junichi Yananose

Yay! I’m back with another board burr – This time, it’s number 4 of the 6 burr series. Thank God it’s not number 3!

This is another beautiful puzzle that utilizes Hickory and Rose Alder with pins of Bamboo. The two wood varieties achieve a nice contrast and while not exotic looking, this puzzle has a subtle beauty that is very pleasing.

This puzzle was a joy to play with. The moves are fun and satisfying. It was a bit tricky at first, although the start is very limited, the puzzle soon hits a dead end and it’s a bit difficult to figure out.

The key with this puzzle, in my opinion, is to really try to accomplish specific moves and positions. With the previous 3 board burr puzzles, I would mostly just explore every possibility with no other intention in mind. It felt impossible to actually try to solve the puzzle. Instead I was left wandering around, moving back and forth until something new opened up. With #4, I was able to determine which piece needed to come out first and was then able to strategically figure out moves to make that happen. This made it more rewarding to solve. There were even a couple of a-ha moments that really stood out.

There is one pin and groove in particular that was hidden the entire puzzle. This made things challenging, yet fun. I kept wondering why the heck certain pieces wouldn’t move as expected – turns out they were held in place by this hidden pin and groove.

I found myself a bit stuck toward the end of this puzzle – I had in fact solved it, and all I had to do was slide the piece free, but I kept searching for more. When I finally slid the piece off, I felt silly for not trying it sooner. After removing the first piece, there is still a challenge left to remove the remaining pieces.

Some interesting channels, notches and two types of pins make for some fun moves.

To me, this is a classic board burr puzzle. It’s approachable and would likely take a novice a long time to solve, but the solution isn’t terribly difficult – just keep at it and you’ll get there. Where #3 had endless pathways, dead ends and was difficult to keep track of, #4 was far more straightforward. There were some hidden moves, and a few tricks to unlock a certain piece, but overall this was a great puzzle that has given me motivation to continue with the series.

Bring on #5!

Final thought – This series is criminally underrated. There are only a few reviews online and further, a couple example have sold on the Cubicdissection marketplace for ~$60-$80 each. Perhaps board burrs are not that desirable to collectors, but these 6 Burrs stand at the top of my collection. I’ve gotten dozens of hours of very challenging puzzling out of them and they are large, heavy and well-made. What’s not to love?

Grooved 6 Board Burr #3 – Junichi Yananose

Oh boy, this one is going to be tough. I’ve been manipulating it for a casual 15 minutes and can already tell that I’m going to struggle. There are multiple paths to start with and they all seem to get complicated real quick. I’m attempting to map this thing out, but it’s going to be exceedingly difficult to keep track of the moves. It’s not simple board moves, it’s block changing multi-piece moves straight out of the gate and unless I take a photo of each move, or draw it out on paper, I’m not sure my brain can handle it. It takes something like 33 moves to get the first piece out, so I’m going to need all the luck I can get.

Ok. I think I’m making some progress. Out of the 3 beginning options, I think I’ve narrowed it down to only one path. The other 2 has multiple forks, but all came to an end within a handful of moves. That only leaves one option. Time to explore further.

Hmm. Thought I was on the right track, made it about 10 moves in, but then found another dead end, so I must have missed something. Time for bed. I’ll live to fight another day.

Day two. Stuck again after about 14 moves. This thing is tricky!

Day three, Day Four, Day Five. I’m losing a little hope here. I find myself in the familiar position of trying the same thing over and over hoping for a different result. But, as you can imagine, nothing different happens. No progress. What did I miss where is the move?

Day Six and I’ve found a new move that shifts things slightly. It seems to dead end though. The promising new move isn’t so promising after all. But it is something different, so there’s that.

One of the many complicated configurations found in this puzzle

After more tinkering, I found yet another move which allowed piece to be moved to their furtherst extend. But, maddeningly, they would not release! More tinkering and I found a way to remove the first piece! But, it requires a rotation. Juno mentions a shortcut using a rotation to remove the second piece, but I haven’t read anything about the rotation I found. Should I use this rotation or should I continue my search for the correct move. Well, I’d like to do it correctly, so no rotation for me.

OK. Officially frustrated. My careful, controlled approach is failing me. I’ve now resorted to uncontrolled fidgeting and manipulation. I’m now attempting to change the orientation of the puzzle in order to get my brain to think about different moves. I’ve traced the same moves over and over so many times that I’m now conditioned to solving the puzzle wrongly. Hopefully flipping the puzzle over, will allow me to see moves I hadn’t seen before because clearly I’m missing something.

Breakthrough!!!

This is one epic puzzle. My god. This thing is complex. I’ve finally taken the first piece out and it was completely unintentional. I had a breakthrough moment where I found a completely new path that I had never explored. I was certain that I was finally getting close, but again I found a dead end. I decided to retrace the steps to take it back to the beginning and search for a missing path. But somehow, on the path back to the beginning, I apparently found the correct path and though I thought I was going back to the start, pieces just kept moving and moves just kept appearing where they hadn’t before and I just decided to forge ahead, getting completely lost in the process. I was in awe as the puzzle moved further and further apart but still held together. My god, how can a single puzzle have so many paths?

So here I sit, with one piece out and once again, I’m stuck and can’t get any more pieces out. This puzzle is relentless!

Omg. I’m ready to break out the saw or hammer on this puzzle. I’m going to have to come back another day to try to remove the next piece. I’m just frantically moving pieces around hoping and praying that something will release. But NOOOOO. This puzzle has other ideas. Dammit Juno. How the hell did you design this diabolical thing?

I have finally done it. This has to be one of the most difficult puzzles I’ve ever disassembled. This thing is unreal. Taking out the second and even the third piece took me over an hour. It seems you have to backtrack a crazy amount of moves – pretty much back to the beginning to take yet another path to release that 2nd piece. It’s the puzzle that never ends.

In the end, I didn’t feel joy at solving this, I just felt relief.

The pieces don’t look so intimidating, but trust me, this thing is very challenging.

There is absolutely no way I would ever be able to reassemble this thing. I’ll have to resort to the burr file – which will be a first for me. But I just can’t imagine even attempting to put this back together.

In the end, I did contact Pluredro and they quickly sent out the Burr Tools file. I loaded it up and managed to put this thing back together. Even that was not easy. I’m not well versed in Burr Tools and had to spend a good amount of time going through step by step, rotating the puzzle around on the screen to make sure I had everything correct. The process confirmed, once again, that this is a very difficult puzzle.

The thoughts of solving 4,5 and 6 doesn’t sound very appealing at the moment. But, I’ve set out with a goal, so I’m going to give it the best I’ve got. Hopefully the next ones aren’t as ruthless.

Grooved 6 Board Burr #2 – Junichi Yananose

Here we go again! This time with Grooved 6 Board Burr #2

This one is supposed to be much easier than the first. We shall see!

Before we begin, I have to talk about the beauty of this thing. It’s incredible. Constructed of Bubinga and European Beech, it is much heavier than the first and in my opinion, is even better looking. The Bubinga has a wonderful wood grain throughout and it is nicely contrasted by the lighter, yellowish Beech. Also of note is the lack of visible grooves and pins. They are still in there, you just can’t see them without moving pieces around. I love this concept – the idea of creating a simple looking puzzle that hides all the intricacies internally that are only revealed through manipulation. There’s no way to plan ahead with this puzzle, you have to start solving in order to learn how to solve it. Very cool.

The description includes “..but we believe that many burr puzzle lovers can assemble the puzzle without any clue.” Challenge accepted! With the previous puzzle, I utilized stickers and photos for reassembly. This time, I’m going to give it a shot without those aids. Wish me luck!

As with the first puzzle in the series, this one is a joy to hold and manipulate. The pieces slide easily and the heavy nature of the wood makes for solid sounding “thunks” and “claps” as the pieces are pushed and pulled.

Wow. First impressions – I’m stunned. This puzzle isn’t what I expected. There seem to be numerous ‘half-moves’ involved and the puzzle quickly becomes a little loosey goosey and that makes it hard to keep track of what the heck I’m doing. I like to backtrack often in order to keep an idea of where I’m at with a puzzle, but I’m having a hard time doing that here, so I have just pushed forward.

I soon found a move where I thought that pieces would come out, but at the last second, they stopped and I wasn’t able to remove them after all. Super fun and exciting, but slightly intimidating.

After this, I once again decided to return the puzzle to the original state. The next day, I set about again and could only get about 6 or so moves in. I couldn’t seem to find the move that I completed the previous day. I became rather frustrated as I knew this move was so close, but I just couldn’t unlock it! Gahh!

Well, eventually I found it and it was again thrilling to see the pieces slide all the way to the edge without coming out. What the heck was holding it together? I reworked this move a few times and eventually discovered what I had been doing wrong. Now that I was familiar with these moves, I decided to press on again.

Pieces sliding way out! Close, but no cigar!

This led to more interesting moves – there are a number of times with this puzzle where a series of micro-moves are required. It is great fun, but hard for my brain to comprehend. At last I came to a configuration that once again felt like pieces could fall out and sure enough a piece dropped out the bottom while I was holding it. Had I solved it? Was this the intended solution?

It’s hard to say, by my count, I was only about 19 moves in and Juno’s description says 25 to get the first piece out. Hmm. So, I put the piece back in to check for more moves. Sure enough, I found a couple more of those micro-moves that allowed me to remove the first piece in a much more elegant manner. Ta Da!

Fun, Fun Fun! What a very cool puzzle. The inner workings of this puzzle are a wonder to behold! And to my surprise, 2 of the pieces were complete rings, with no grooves or pins at all! Juno has done it again!

Now, the question remains, Can I reassemble this thing without relying on my notes or photographs? I’m going to come back in a day to let the memory of the positioning and movement fade a bit and see if I can do it!

Ok, let’s see if we can do this. How hard can it be? Looking at the pieces, it is fairly obvious as to how it should go together. There’s only 2 boards that have pins. And there’s also only 2 boards that have grooves. It’s also fairly obvious which pin board goes with which groove board, so now all I have to do is actually assemble the shape.

So far, assembly isn’t going too well. I am quite sure I know which pieces fit where, but at present, they won’t go back together. I’m going to keep at it for an hour or so and see if I can make some progress, but so far, no luck.

Holy crap I did it! With enough tinkering and guesswork, I finally figured out the arrangement necessary to put it back together. I got some strange looks from my family (and dog) as I was shouting “Yes! YES! YEEESSSS!” but it was certainly worth it. Really, it wasn’t that difficult, I already knew which piece had to go together and I was pretty sure about their orientation, it was just a matter of figuring out how to get them together. In truth, the pins and channels guided the way. I extended the board pairs to their maximum – essentially putting the pins at the end of their grooves and then tried to assemble the thing. Pretty quickly I knew I was on the right track and in fact the assembly went together rather quickly from this point.

Overall, another fantastic puzzle. Definitely way easier than #1 and I’d say this puzzle is even approachable to folks who are new to puzzles.

Two down, 4 to go!

Pinned Framed Burr S – Junichi Yananose

Woot! Another Juno puzzle from Pluredro.com! I don’t buy a lot of puzzles from Pluredro, but this one looked unique, so I couldn’t resist.

This is yet another puzzle that I’ve been ignoring for too long. Released back in February 2020, I purchased this puzzle, along with the “L” version. Both have been sitting in a box in the basement awaiting my attention. Well, I’ve been on a puzzling binge lately, so let’s get started!

The construction of this puzzle is very nice. The framed box is super solid and the burr sticks feel substantial. If anything, this puzzle has a rather plain appearance. It doesn’t scream “pick me up!” like other puzzles do. But looks can be deceiving and the real allure of this puzzle is hidden away, out of sight.

There is a nice audible click and clack as I play with the puzzle which is super pleasing. It’s a borderline fidget toy as you can just sit there and watch tv while pleasantly click and clacking away. Every once in a while you find a new move and the piece push further into the frame which is very satisfying and encourages continued exploration.

The objective of this puzzle is to remove the 4 burr sticks. The burr sticks move by pushing on them, but hidden within the puzzle are an unknown number of pins and channels which must be negotiated in order to remove the pieces. The fact that these elements are hidden really adds to the fun and difficulty of this puzzle.

Pieces move in, pieces move out. Am I making progress? I don’t know.

I didn’t know how to approach this puzzle, so I just played with it. I thought about trying to map out the path that the pins follow, but the problem with that is that I can’t see the pins, don’t know how many there are or where they are located. So, mapping seems out of the question.

In the end, I didn’t even try to keep track of things, I just set my mind to removing the burr sticks and proceeded with a semi-reckless determination to just make it happen. And after many hours, I succeeded!

I was sitting on the couch pushing the burr pieces around (most of the time, I didn’t even focus on what I was doing) and suddenly a piece landed in my lap! Whelp, guess I did it!

Pieces removed. Very interesting arrangement of pins and channels for this puzzle!

Removing the rest of the pieces was a little challenging as it turns out some of the pins are offset, so they can only be removed after the first piece comes out. There’s definitely some hidden trickery happening here and it’s very, very interesting to handle these burr sticks and see how they interact with each other inside the frame.

After taking some photos and admiring the craftsmanship, I set to put it back together. Oh boy! I was expecting things to go relatively smoothly, but turns out re-assembly is quite difficult indeed! My first attempt failed. I think I put things together wrong in a way that would never be able to be solved. Some of the pieces moved around and I thought I was putting it back together, but there was one piece that didn’t seem to “engage” the other pieces, so I eventually had to back track, remove the pieces again and start assembly over.

I think I went through this process 3-4 times, spending hours trying to reassemble the puzzle with piece in the wrong place. Eventually, I got fed up with things, pulled all the pieces out and decided I needed to be more systematic. I examined the pieces, how they interact and tried to really understand things to help me better assemble.

I discovered that there were a couple of different ways to insert the burr stick that fell out first. One of the ways lead to dead ends, the other lead to the solution. It was true, I had been doing it wrong, so I tried the second option and things started to go together better. It still took me a couple of hours to get the puzzle back together though!

Wow! what a challenge. I really thought this would be more straightforward and easy, but it proved to be a worthy adversary. I’m quite scared to try the “L” version, as it looks way more complicated, which is scary indeed. Thanks Juno! I enjoyed this one.

Sequential Discovery Burred Box – Junichi Yananose

Oh man, I’m so excited. I just received a package in the mail from Pluredro.com and I am now the proud owner of the Sequential Discovery Burred Box! This particular box was announced on social media (as far as I know) and sold out super quick (In 5 days!). I was on vacation at the time, but managed to sneak an order in when inventory was down to only 3 or 4. Well, I’m glad I put in the order, because this puzzle sure looks like fun.

A Quick Warning! – I’ve tried hard not to include any spoilers in my write-up, BUT, if you own this puzzle and haven’t yet solved it, I would avoid reading any further. You have been warned!

The only spoiler-free image I can show! Many secrets hidden inside this puzzle.

I’m going to do a running commentary for this blog post – I’ll write down my thoughts as they come and try to share in the discovery of solving this puzzle (hopefully!) I want to be careful not to post any spoilers, but also want to share the process – the successes, the failures, the frustrations and ultimately, the triumph! Let’s get started.

This puzzle is super unique. It is a sequential puzzle, that also has a small cavity inside. Is it a puzzle box? Is it a burr? Is it sequential? Yes, yes and yes!

My initial impression is that it is pretty big. It is bigger than my hand, and yet despite that, it is surprisingly light. It is hard to believe that there is a sequential puzzle box incorporated into this common 6-burr shape – but we shall see.

My initial inspection doesn’t reveal much. There are no loose pieces rattling around inside and there is not obvious initial move. It feels solid with very little play between the burr pieces. Closer inspection reveals that there aren’t 6 separate burr pieces either – some of them are fused together or made from a single piece of wood. Ok, enough of the examining, its time to start working on it and see what happens!

Wow! Very quickly, I’ve made my first discovery – and it is pretty exciting. That quick rush of adrenaline that spiked up and down my spine is exactly why I love puzzles. Without revealing any spoilers, I can say that this first discovery has revealed some of the puzzle’s interior and also given me access to a “tool” of sorts. I’ll see if I can put that to use…

But before I use the “tool” I’ve discovered that there are now some movements possible that weren’t possible before. And it’s even more exciting because this new movement now opens up some more areas and also unlocks an additional piece. This is really cool stuff and despite my skepticism this puzzle does indeed hide more secrets than seemed possible.

I’ve managed to use the tool and one of the pieces to make another move and now I am stuck. Is the puzzle solved or is there more to it? I fiddle some more and am feeling pretty certain that there is more to do here. There is still another area that I haven’t touched and then I discover there is also another tool to use! I can use the first tool to free the second! I’m having so much fun here!

There aren’t a lot of options left at this point but I still have to try out a couple of alternatives to see what works. Finally, I notice an area that I had not yet utilized and it just so happened to be the exact size to fit one of the other pieces… But I didn’t have things oriented correctly, so had to give it a second try and YES! I’ve done it! One last little trick and I’ve discovered the small cavity and the “Juno” brand! Wow. That was so cool!

One more shot of puzzle. Very clever indeed.

I’m just amazed at how much was packed into this puzzle. True, it’s not a small puzzle, but my first impression was that it would be pretty simple, and in fact it turned out to have many more moves and sequences than I thought it would have. Lesson learned – don’t judge a puzzle my its’ weight!

Overall, this puzzle was delightful. I really, really enjoyed it and hope that Juno makes many more of these types of puzzles – in fact, I may have to purchase one of his puzzle boxes because I enjoyed this so much. While this particular puzzle is no longer available, its popularity and quick-selling performance makes me confident that there will be more of this type coming in the next year – and I can’t wait!
