TRIAD – Osanori Yamamoto

This week, I have Triad, designed by Osanori Yamamoto and built by Jakub Dvorak of Pelikan Puzzles. I purchased all the recent Pelikan puzzles – minus Excalibur – and will be writing my thoughts on all of them over the next couple of months.

This was the first of six puzzles that I opened and immediately I am made aware of how beautiful Pelikan Puzzles are. They are so well made, the tolerances are so small and the wood choices are impeccable. The difference between these and other puzzles is immediate. These puzzles are absolute works of art.

This particular puzzle contains 3 burr-type pieces enclosed in an open framed box. The pieces appear to be identical in shape, though Jakub has wisely chosen 3 different types of wood. This puzzle is smaller than the others, but that’s ok because I’m running out of room on my puzzle shelf!

This puzzle seems fairly straightforward. The three pieces can each slide independently of each other and there are no internal stoppers or notches in the framed box. It seems that it is just a matter of finding the proper sequence to remove the first piece. I would expect that the second and third piece fall out once the first is gone.

After playing around with this thing for a few minutes, I have a couple of observations. First, the pieces are not identical, there is a definite difference – though they all seem to share a similar forked end, there are seemingly some variations between the pieces. The second thing I noticed, is that this puzzle is a little trickier than I had initially thought.

The pieces move in and out and conveniently shift to make room

After about 20 more minutes of work, I have the puzzle disassembled. The moves are not too difficult to figure out and I don’t remember any dead ends, so it seems like a fairly linear path to resolution. Despite my initial prediction, once I had the first piece out, the remaining two pieces DID NOT just fall out. In fact, the final two pieces were pretty tricky. I had several “incredulous head shakes” at my own expense while trying to remove those final 2 pieces. There is definitely a particular sequence, even though it feels like it should be easy.

The pieces have been removed, now time to assemble

I’m a bit nervous about re-assembly though – I’ve made the decision to scramble the pieces and not reference any photos to attempt the re-assembly – wish me luck..

But before I re-assemble. Let me take a moment to once again point out how beautiful and well-made these puzzles are. I’ve examined the pieces thoroughly and am truly impressed by the workmanship. Everything is just perfect and precise. In fact, I’m out of adjectives to describe it. There’s just something incredibly satisfying about holding perfectly accurate wood structures…. Ok. back to it..

Well assembly is not easy. I’m still working on it, but I’ve noticed something very obvious that I had overlooked… The framed box isn’t square. Yeah, I know, super obvious, but for some reason, it didn’t really register. But since the 3 internal pieces are not all the same length, it is now clear which pieces are horizontal pieces and which one goes in a vertical orientation…

Yes! I’ve re-assembled the puzzle and it was super fun. This is a great little puzzle. It’s one of those puzzles with a perfect balance of difficulty and intrigue. It seems almost impossible at times, but there are enough clues available to sort of funnel you into the correct solution. Since the box is open, you can see inside and see all the movements. Thus, using a little logic, you can determine what pieces need to go where – they simply wouldn’t fit in a different orientation. So, armed with a little knowledge and determination, I think this puzzle is very doable for even a novice puzzler.

Solved puzzle was fun, picture is a little crooked.

Theres one or two clever little moves that allow this puzzle to work and I’m excited to run through this one a few times to see if I can really master what is happening.

The other thing to mention is that this puzzle requires zero rotations. There were a few times where the pieces “wanted” to rotate and I thought that maybe I could remove one with rotations, but I resisted the urge and you should too. Thanks to the incredibly precise nature of this puzzle, it was obvious that rotations were not correct, but if this puzzle were looser – it would be easy to accidentally rotate a piece.

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!

Okto Cube – Yavuz Demirhan

Today, we have another beauty from Eric over at Cubicdissection.com. This one is called Okto Cube and was designed by Yavuz Demirhan. This particular puzzle immediately caught my eye when it was listed, and I was very excited to work on it. I love the looks of it and it was equally fun to manipulate and discover it’s secrets.

This is a six piece board burr encased in an eight piece cube. The cube pieces are made out of solid wood which gives this puzzle an overall weight that is pleasing and the boards are well made and strong.

Solving this puzzle took a while. I brought it with me on Thanksgiving vacation, hoping that I would have some quiet evenings to work on it. Well, I didn’t have many quiet evenings, but I did get to work on it extensively, which was great.

I had played with this puzzle a handful of times before I made any real progress. I could move a few of the burr pieces, but always hit the same dead end. Eventually, I discovered that it wasn’t a dead end after all. Once in the “dead end” position, I found that the signed burr piece could move freely. I had missed this move because its quite easy for the pieces to bind up a little. I often had to pull on board pieces to make sure they were fully extended before manipulating the next piece. It seems to loosen up after a bit of use, but is something to watch out for.

Once, the signed burr piece moved, I was then able to remove 2 of the cube pieces, which was a very cool (and scary) moment. I was expecting the puzzle to fall apart at this point, but that wasn’t the case at all, in fact, I had a long way to go.

The Signed board makes an appearance and one cube is removed.

Removing the 2 cube pieces revealed more of the interior and allowed me to see just how complex this puzzle is. There sure are lots of moving parts! I continued to manipulate the puzzle and was able to remove the first board piece. Soon after, I found that 2 more cubes were ready to fall off. Awesome! This thing is really fun.

4 cubes and a board removed. This puzzle is fun!

I continued to manipulate the parts feeling certain that I was close to the end. But no.. the puzzle still held secrets for me to unravel. I persevered and after a bit more manipulation and I removed 2 more cubes! I was now down to the final 2 cubes!

This is where things got really interesting for me. I was working on the puzzle in front of the tv, sitting with family, and I just didn’t have the focus I needed. I began to worry that I wouldn’t be able to get it back together again! I was hoping that the final 2 cubes would come off easily, but that wasn’t the case. I was having to do more movements than I could keep track of and I made the decision to stop and reassemble. Bah! I always seem to do this. Luckily, I was able to get the puzzle back together, but I was a bit ashamed that I didn’t finish it.

I ended my vacation and flew home defeated. I had come so close to the solution, but didn’t quite get there.

Well, last night, I sat down, determined to redeem myself and finally solve this puzzle. I progressed through all the stages and once again found myself with the final 2 cube pieces attached to 4 burrs. I slowed myself down and analyzed the situation. There were a surprising amount of available moves and positions that I could find and eventually, I tried a combination of positions not previously attempted and voila! The 2 remaining cubes slid right off! Disassembling the final 4 burr pieces was not trivial either, but I got it done.

Whew! That was an awesome puzzle!

But.. it wasn’t over yet. I still had to assemble the puzzle. Interestingly, I didn’t have much trouble on the assembly. I think that my aborted attempt during thanksgiving vacation had given me a better understanding of the moves required, and so assembly felt rather easy. I think the most difficult part was getting it started. For some reason, I seem to have trouble assembling the initial 4 burr pieces. But once that is complete and I had slid on the first two cubes, it was all downhill from there.

I’ve since solved this puzzle a couple of times. I had to take some pictures and also wanted to better understand the mechanics behind it all. It is truly a remarkable puzzle and it is very repeatable once you understand the required positions. This is now one of my favorite puzzles! Check it out if you can!

Two Face 3 – Alfons Eyckmans

This week, I have another fantastic burr puzzle created by Eric Fuller and designed by Alfons Eyckmans. This one is called Two Face 3 and is one special puzzle – I’m still reeling from having just completed it.

To begin with, this puzzle is a beautiful work of art. Its visual appearance is stunning – the construction is superb and the choice of woods really elevates the whole design. It’s a 6 piece burr, but unique in that there are two outer cages that can move independently of each other. The inner cage has a few strategically placed cubes and cutouts that combine to make this not only a difficult puzzle, but also a very clever one. The construction of the cages is incredibly sturdy and they fit together very tightly making for a very solid feeling puzzle.

Beautiful construction and and high difficulty make this puzzle shine

The overall design is very clever. The use of two cages is not just for looks either, it factors into the solution.

This was another intimidating puzzle for me. It sat on the shelf for a couple of weeks before I started to tinker with it, and then it was another week until I really decided to put some effort into it. Whether it’s intimidation or a desire to relish the puzzle as long as possible, I find that sometimes, I’m just content to let it sit. Maybe I don’t want the experience to be over, so I procrastinate a bit, I let the puzzle breath like a fine wine, until that perfect moment arrives and then I sit down with a job to do.

And so, I finally sat down with this one last week and began to seriously work on it. I began exploring different moves and discovered some typical burr-type moves, but didn’t make any real progress. I kept going in circles, with no real progress made.

I spent a number of sessions doing this. Moving pieces, feeling like progress was made only to find myself back at the beginning. Early sessions like this are enjoyable to me – I don’t really want to solve it quickly, I just want to enjoy the experience for a while and Two Face 3 really delivered the goods. But, that said, after a certain number of sessions, i start to feel like I need to make some more progress – so, I increase my focus and start trying abnormal moves.

This yielded some success for me as I discovered an interesting placement for one of the pieces. Surely I was on to something here! But, even with this new discovery, I couldn’t make any progress. I was able to revert back to the beginning position and then repeat the move, but it still didn’t yield any solution.

After a few more sessions, I discovered a similar move at another location and then knew I was making progress. But, to my dismay, the solution still wasn’t there. Man, this puzzle really takes some work! I spent another day working various moves but couldn’t make progress. I had to be on the right track didn’t I?

Well, one morning, I took the half-solved puzzle to work with me and sat there fiddling with the pieces when suddenly, one fell out! Holy crap! I didn’t expect that, but apparently I had done the right thing and was rewarded. I spent the next 15 minutes carefully removing the remaining pieces and then bathed in glory as I examined all the pieces and marveled at the craftsmanship.

Then, fear set in. I went from joyful elation to fear. I was so happy to have solved the puzzle that I forgot to pay attention to the orientation and position of the 2 cages and the burr pieces. I didn’t really think about the fact that the 2 cages could be put together in 8 different ways… and if they weren’t put together correctly, then there’s no way the burr pieces would fit… How on earth was I going to get this thing back together…?

All the pieces have been removed! Halfway there!

Well, the good news was I had taken various photos while tinkering with the puzzle. So, I went back and took a look at those photos and was able to deduce the orientation and placement of the 2 cages – phew – crisis averted. Although, that would have made one heck of a challenge – to start with this puzzle completely disassembled and go from there. Maybe one day..

Anyway, even though I had the orientation of the cages documented, I still didn’t know how to reassemble this thing. I did keep track of the order in which I removed the burr pieces, and that would prove helpful, but it wouldn’t move the puzzle for me.

In the end it took me at least another 3 hours to put it back together. It’s a tricky puzzle and requires a very specific sequence to solve it. Interestingly, I employed a rotation to put it back together – I’m not convinced that it was entirely necessary, but at a certain point, rotating the burr piece allowed another piece to move where I wanted it and then I rotated the original piece back. Again, not sure if it was necessary, but I remember playing with a rotation when disassembling too, so perhaps it is required.

This may be the most difficult burr puzzle I’ve ever solved and I thoroughly enjoyed it. I’m not eager to solve it again anytime soon, but I do think I will revisit it one day and see if I can get a better handle on how it works. Highly recommended if you enjoy this type of puzzle – and there are even some left at cubicdissection.com

Six Rings #2 – Andrew Crowell

Today, I’m looking at a puzzle designed by Andrew Crowell and built by Brian Menold at Woodwonders. This is my first purchase from Brian, but it definitely won’t be my last. In fact, I’m having a hard time not pulling the trigger on the Perfect 11 and Evolution II puzzles still available on his site. Where does one draw the line when it comes to purchasing puzzles?

I was attracted to the description of this puzzle – “I learned that Andrew had written his own program to design his puzzles. He was able to come up with some very creative rotations in this way.” Creative rotations sound fun and a custom program to design puzzles? Color me intrigued!

Anyway, the puzzle arrived quickly along with a couple of other ones I had ordered, and Brian even threw in a free gift puzzle since I was a first time customer. Awesome! (I’m still working on the gift puzzle..) And my first impression of these puzzles – They smell great! No, seriously, these puzzles have a unique smell and I can’t get enough. There must be a light stain or oil on the wood, and as weird as it may sound, I was delighted to rip open the shrink wrap and awaken my olfactory senses. In my mind, I was transported to the workshop and could feel the fine craftsmanship oozing from the mix of woods.

Ok, ok, enough of how the puzzles smell. How do they solve? Well, this is one interesting puzzle. It really has some fun moves and the shapes are so unusual that it presents a nice challenge.

I spent the first 5 minutes just trying to get something to move. The puzzle felt solid and tight and no matter how I tried to pull, push and twist, I couldn’t get anything to budge. This made me happy, clearly there was something going on that I hadn’t figured out yet. The puzzle required me to focus, to concentrate, this wasn’t going to be an easy stroll through the park.

Where to begin? Push and Pull as I might, the cube didn’t budge.

After a few more minutes of play, I found the opening move and shortly after that I discovered the first rotation. Wow, this is a really fun move that I had to repeat over and over because it was just so well executed.

Finally, I was ready to move on and solve this thing. But alas, I was stuck. Surely I had the opening moves correct, but I wasn’t sure about the 5th move. There was a small “trapped” piece on the inside of the cube and I spent a good amount of time manipulating that piece. It could rotate a few different ways and there were several pockets it could be moved into. However, none of these options seemed to release any pieces.

It only takes a few moves to turn this symmetrical cube into a lopsided monstrosity.

I re-assembled the puzzle and started again. I wasn’t in a hurry to solve it because the opening moves were fun to execute, but eventually, I had to move on, so I tried something different and finally discovered how to unlock the first piece. The trapped piece came out next and I was left with only 3 pieces.

I don’t want to spoil anything, but the way these 3 larger pieces interlock is really quite beautiful. It isn’t particularly difficult to get them apart – In fact the pieces are so unique that there aren’t that many options for them to move, but it is very satisfying and even a little surprising how they interact.

The first time I re-assembled the puzzle I was a little intimidated. I didn’t spend much time memorizing positions or anything, I just figured I could get it back together – and I was right, it’s not too difficult, a little perseverance will do the trick. But, it sure was fun.

This is a very enjoyable puzzle that had enough surprises to keep me interested and was difficult enough to keep me engaged. There is one rotation in particular that is very enjoyable and made me feel like Indiana Jones pulling the lever on some ancient treasure. I think the tolerances, build quality and design all work together to really make this puzzle shine. I look forward to purchasing many more puzzles from Andrew and Brian both.

The Puzzle is disassembled. Take a look at those funky pieces!

TRAP-R2 – Osanori Yamamoto

Today, I have an very interesting puzzle called TRAP-R2 designed by Osanori Yamamoto and crafted by Pelikan Puzzles. It’s only a 4 move puzzle, but those 4 moves aren’t as easy or straightforward as it may seem.

The puzzle itself is beautiful. It reminds me of a double decker coaster, but I won’t be setting my beer on it anytime soon. The two coasters are separated by 4 corner posts and in between is a circle of wood that can be spun around. Spinning the circle reveals something unseen – some sort of impediment that prevents it from moving smoothly around. The thing is, you can’t see what is happening, so you have to work out what to do by feel.

It doesn’t take long before pieces begin to move, but the first available movement isn’t necessarily the correct one. What makes this puzzle really work is the fact that the tolerances are so tight. The pieces have to be in the exact correct position in order to solve it. This can be a little frustrating because if you are just a millimeter off, it won’t budge.

Super Tight pieces make this a challenge.

The first time I solved it was a complete fluke, I was just playing with it and manipulating the pieces, when viola!, it came apart. I studied the internal pieces a bit and thought “hmm, that’s not so difficult” and managed to put it back together. Confident that I knew how to solve it, I tried to repeat the process, but this time, I couldn’t open it! How can that be? I had solved it and seen its’ secrets. But nevertheless, it took me longer than I’d like to admit to solve it again.

Challenging for me to wrap my head around, even when solved.

This time, I was more determined to figure out what was going on. I don’t know if my tiny brain was just misfiring, but it was surprisingly tricky for me to figure out. There are really only 2 internal pieces and the circle so it can’t be that hard, I thought, but sure enough, it was still a bit perplexing. The way the two internal pieces fit together is rather clever and figuring out how to free that circle took me a while.

I did some mock assemblies, where I really tried to get a grasp of the exact movements required to solve it and finally was able to understand exactly what needed to happen. But despite this knowledge, it is still challenging for me to solve it – mostly because of the tolerances and the fact that there are no significant markings available to use for orientation.

Seems like it should be straightforward, but it’s not.

Overall, I really like this puzzle and am happy to have it in my collection – however, I would only recommend it for hard-core collectors. I think its probably a bit too expensive for the average puzzler. There are still some available at Puzzle Master, but I think, for the money, you could get something with a bit more repeatability to it. Still, if you’re like me and just can’t resist spending all your money on beautifully crafted puzzles, this one may be worth it, and if you know someone who owns this puzzle, definitely give it a shot!

Hanayama Infinity

Ok. Gonna do another real time run through with the Hanayama Infinity. I haven’t played with this one before, so this will all be done on the fly. I’ll start on the puzzle and every so often – 5 or 10 minutes, I’ll stop and record my progress and thoughts. Maybe this will reveal something interesting about the process – maybe not. But, its the process of solving these puzzles that I want to capture here. Solving puzzles is about being systematic and exploratory. Lets see if I can get this one solved here tonight.

First off, the puzzle is another beauty. Like most Hanayama puzzles, they are usually bigger and heavier than I anticipate from the picture. This one looks like its made of 3 pieces. 2 circular bearings and an outer casing. One thing that I notice right away is that each bearing has a circular cut-out where the other bearing fits. From the picture, I figures only ONE of the bearings had this cutout, but upon flipping the puzzle, I can see that both have this cutout.

Ok, lets see if I can discover anything in 5 minutes.

Five minutes in and I haven’t solved it, but I have learned a few things. I’ve been able to manipulate the two bearings a bit and am starting to understand how the puzzle moves. The two bearings are able to rotate around – i haven’t been able to complete a full 360 either. I’ve gotten the stamped bearing to rotate probably 300 degrees, and the blank bearing only about 15 degrees. The bearings also can move up or down and moving them up and down unlocks the turning ability. The sides of the bearings are visible at times and I can see interesting shapes and tracks that are interlocking on each other and preventing or allowing movement.

Solving the puzzle will likely be a matter of knowing the correct position and/or sequence to release the two bearings. I’m not sure if I can take a systematic approach or not. I felt like I was making some progress in the first 5 minutes, lets see what happens next.

Ok, I’m now 15 minutes into this and I feel like I’m getting close. I’m pretty sure I have one of the bearings in the correct location. There is a scallop cutout that is lining up with a protrusion on the case. But, the other bearing isn’t budging and right now it feels a bit stuck. But, I’m hesitant to move the piece that is the correct position. But looks like thats exactly what I’ll have to do if I want to progress.

This puzzle is fun to manipulate, but is a little frustrating because pieces seem to lock up at points. I don’t yet know if this is sequential in any manner or whether I just need to get the pieces into the correct position.

32 minutes and 54 seconds total time, and the puzzle has been solved. I’m not sure if I did things correctly or not. It seemed to me like I could rotate the stamped bearing fairly easily, but the non-stamped one was difficult to move. I ended up moving the stamped bearing around about 300 degrees and then that would allow the non-stamped piece to move about 15 degrees, and I’d move the stamped piece back to the start and that would allow me to move the other piece 15 degrees. I kept at this until the puzzle was solved.

Hanayama Cast Infinity Solved — Sovled! You can see the “scallops” on the inside of the casing

The inside of this one is really cool. Its really amazing to interlock the bearings and move them around and see how they catch on each other and how moving up and down opens up new pathways. Overall, I’m very impressed with the design on this one. It seemed obvious from looking at it how it would work, but its design makes it really challenging. I think I’m going to hold off on putting this back together – I need to understand how the bearings interact better to see if I did things correctly or picked an inefficient solution.

Assembly was pretty straightforward, but still took me a good 10 minutes to complete. Overall, I really enjoyed this one. I’ll have to complete it a few more times to see if I can really get a mastery of it.

Hanayama Cast Infinity — Back together again.

Hanayama Cast Elk

Ok, new format. Tonight, I’m going to document the puzzle solving experience. I have the Hanayama Cast Elk puzzle and I’m going to try to solve it while documenting my thoughts every 15 minutes. Hopefully this will capture the process or evolution of solving one of these things. I’m also hoping that I will perform better due to the greater focus required. Anyway, we’ll see what happens.

Begin: (first impression) – My initial though is – “how hard can it be?” I mean it’s only 2 pieces. Surely there can’t be that many ways to manipulate the two pieces, right? Beyond that, the puzzle is another excellent Hanayama. It has good weight to it, it has a nice shiny finish – similar to vortex. And, overall, its just pleasing to hold. Let’s see what I can figure out.

Only two pieces, but still tricky to solve.

Whelp, I solved it in 11:26, so didn’t need the full 15 I guess. It funny, cuz I had the pieces in the final position a few times, but didn’t “make the move” until later on after I had exhausted a few other possibilities. Really, there weren’t that many positions for the pieces to be in, which was making me a little frustrated after the first 5 minutes.

I initially figured out how to move the pieces through each other and felt good, but then I couldn’t progress any further. The pieces were easy to manipulate and many times, they were very close to passing through each other, so much so that I began to think that perhaps this was one of those lopsided puzzles where one protrusion is slightly smaller on one side than the other. I kept chasing this idea for a while – really examining the puzzle to see if there were any anomalies in size or shape.

Ultimately, I didn’t find any anomolies, the puzzle looked symmetrical, even upon close inspection. So, I went back to manipulating the pieces. After a while, it seemed like I had exhausted the possibilites, so as per usual, I concentrated on doing things different. I was trying to go against natural instincts and move pieces opposite to what was natural.

This technique is something I use all the time in puzzling. Trying the same thing over and over doesn’t usually yield results, so consciously doing things differently often helps.

Anyway, just like that, I had the pieces back in a familiar positions but this time, tried a slightly different move and viola! They separated.

After getting them apart, I quickly put them back together again, feeling confident that I knew the secret… except I was wrong… It wasn’t quite as simple as I thought and in fact, I’m confident that I got lucky the first time. Because this time, I was having a harder time finding the solution. It took me a solid 20 minutes to get the darn thing solved again, and I’m feeling confident now that there are in fact some subtle differences in shape and size in the pieces, arms and slots.

Pretty cool puzzle. I definitely don’t have it mastered, i’ll have to solve it a few more times, but it was fun and I liked it a lot – even if I did get lucky.

Pyrigan #360

Last week, I received a package of puzzling goodness from the fine folks at Sloyd.fi The package took a little while to arrive, but it was worth it!

Inside was the Pyrigan #360 – an intriguing nickel-plated aluminum puzzle with an entrapped turquoise ball. This puzzle is wonderfully crafted and has tons of appeal.

8/17 I’m in love with this puzzle. It’s gorgeous, intriguing, and compelling. In my world, this in the pinnacle of puzzling. It’s like holding an alien relic, its full of intrigue and mystique. It’s very well made, it feels heavy and solid and even though I know it comes apart, it is held tight with precision tolerances. It’s begging to be opened. The turquoise ball sits there waiting. You can even touch it – but you can’t have it… yet. I feel like a treasure hunter holding this thing.

I’m going to put in 15 minutes and see if I can discover anything.
Ten minutes in and I am still in love with this puzzle. It is so pleasing to hold and manipulate. Its the perfect size and weight. I’m no further along in solving it, but I do have a few ideas and I have learned a couple of things. I spent a bit of time with my ear pressed up agains each side of the puzzle as I tilted it around trying to decipher what was inside. It sounds to me like there is one very small metal ball along with 2-4 metal rods. Subtle tilts in the 360 will make the small ball roll back and forth, but it takes a bigger angle to make the metal rods shift position.

The other thing I noticed is that if I keep moving it around and pulling and twisting, there are times, were there is slightly more movement/play between the pieces. This leads me to believe that there are several metal rods that are holding this thing together and that rotating/tilting the 360 causes the rods to move. I believe that if the 360 is rotated/tilted/spun in the proper manner, it will open up. There’s not really any other option to open it. I don’t think the blue marble has anything to do with the solution and I don’t believe that I can simply push/pull in an area to open it. There have to be pins on the inside and some manner of moving the 360 will put the pins in the open position.

A close-up look at the seams. Everything is very tight.

8/18 Ok. I have 15 minutes to work. let’s go!….And its solved. 07:29 into the 15 minutes and blammo, she’s a done deal. It happened waaaay quicker than I thought it would. That was pretty damn exhilarating though.. I don’t want to give away the solution, but needless to say, I was manipulating the 360 a bit and it seemed like it loosened up some. I didn’t know if my mind was playing tricks on me, but I could have sworn it was held together very tightly when I first looked at it – now it was a little wiggly. Hmm.. This was encouraging, so I continued the same sort of manipulation and it loosened up even more! At this point I became suspicious that my mind was tricking me, so I stopped what I was doing and tried to reset the puzzle – sure enough, it tightened back up. Clearly I was on to something.

I went back to the original plan and tried again. It eventually loosened up again a bit. So I kept at it and sure enough I could now twist the pieces and create a 1mm gap between them. And then, it was solved. In fact, I think I may have solved it earlier, I just didn’t pull on it correctly.

Inside the secret was revealed, and I have to say – Its really impressive. I don’t want to give it away, but it’s a really clever twist on a classic. My initial prediction of one small ball and 2-4 metal rods wasn’t that far off. And it’s all engineered with such precision – I’m so happy to have this puzzle in my collection and I can’t wait to see what John (the inventor of the puzzle) comes up with for his next puzzle.

Hanayama Cast Dial

Another fun puzzle from Hanayama! I love these puzzles that seem so impossible at the beginning, but slowly reveal the solution over time. This one was wonderful to solve and is very cleverly built.

At first, it just seems that there is no way to make any progress. There is a triangular frame that is made up of 2 pieces and an internal, rotating “dial” that is also made of two pieces. The only thing that stands out is that the 2 dial pieces have different thicknesses. But otherwise, there isn’t much to go on.

The 2 dial pieces can rotate independently, but it doesn’t seem to affect anything. Its a confounding situation to have a puzzle that seemingly has no entry points. Its also a bit frustrating, because there’s not much manipulation to be had here. A lot of Hanayama puzzles consist of 3 intertwined pieces, so you can at least fiddle with them and change positions – but with Dial, there just isn’t much to play with. You can flip the dial and turn the 2 half, but nothing else.

The first time I picked this up, I didn’t get anywhere. It just didn’t seem like there was anything to manipulate. But, as I resisted this puzzle later on, it came to me that I just had to work with what I got.

I noticed some subtle variations when spinning the dial – sometimes, the triangular frame seemed to loosen up a little bit. So, I played around with this for a while. The hard part here, is that it is difficult to grab the frame. I had a good idea on how it would open, but it was hard to apply pressure in the right place. Eventually, I achieved the first move. It was glorious to feel this thing open a bit after a few hours of tinkering.

But, it wasn’t over yet. As I tried to open it further, I accidentally closed it again and had to start over. It was a bit of a bummer, but ultimately helped because the second time around, I was more aware of how it was working.

Eventually, I got the thing open and the internal secrets were revealed. Now, all the turning made sense to me as I could see how things worked mechanically.

The Dial has been opened. The backside of the dials hold the secret.

Reassembly was a bit tricky, but it also revealed to me more of how things work. Once everything was positioned just right, I was able to close the dial back up.

Overall, a very fun puzzle that was quite challenging to me.
