I wasn't fortunate enough to be able to buy one of Junichi Yananose Tornado Burr's when it was offered by either Eric Fuller however I am lucky enough to have a puzzle friend who was kind enough to let me borrow his copy to have a play.
When Brian Young made copies of this puzzle, there were only 30 copies made way back in December 2008. And when you see how it's made you'll understand why. Each piece is made from a single stick, and while it may not be apparent at first look why that's such an issue, I think it will become apparent as you read on.
The first thing that hits you about this puzzle is the scale. At 6" x 6" x 6" this is a very large burr. Brian has taken a great deal of care when finishing the ends of the burr pieces, and each is beautifully detailed, with a fit and finish that you'd expect from a master craftsman such as himself. The fact that this was part of his Craftsman line is really no surprise. The only other person I know of to have attempted this puzzle is Eric Fuller, and having seen his copy, while much smaller, it's every bit as well made!
With a modest 12 pieces in the puzzle, while it would normally be considered a significant challenge, the Tornado is a challenge in an entirely different way. This is no conventional burr puzzle. As I soon found out, no amount of pushing, pulling or tugging on any of the pieces will help you to find the 'first move' that you normally need to get a burr puzzle started. So with that done, what's left? I don't recommend blowing on it, or spinning it as you'll quickly end up dizzy and out of breath. The clue to the puzzle is in the name.
"This ingenious burr was designed by Junichi in May 2007 with "head and hands; no computer". Junichi had the idea for a multiple rotational movement but did not get to finally apply it to a puzzle until he came up with the Tornado Burr. People often ask puzzle designers "What was going on in your head to design this puzzle?" What was going on in Junichi's head when he designed the Tornado Burr? Visualising things going up and down and back and forth at the same time is one thing, but things going up and down, back and forth and around as well is quite another! Junichi says the Tornado Burr "has very eccentric movements" and challenges puzzlers to "Try your luck, and stop this fierce tornado."
Needless to say this puzzle is not solvable in any computer program that we know of.
Eccentric movements indeed! As you can see above, this puzzle has rotations, although not like any you'd have thought about before playing with this puzzle. How Junichi came up with this is beyond me. It's an insane puzzle mechanism, that simply imagining the interactions and movements entirely in your head takes a special type of mind.
Coming back to my comments about the pieces all being solid and the significance of that fact becomes apparent. For the puzzle to work, it needs dowels rather than notches in the pieces. Each of these rods was hand turned on the lathe and has to be very accurately made. Not only that but it is turned on an off centre axis, making things just a little bit scarier! Having done a lot of work on the lathe recently myself, I can truly appreciate the work that goes into making each and every one of these pieces.
At IPP27 in Australia, this puzzle received an Honourable mention. Having had the opportunity to play with one, I can see why. Despite not being a burr fan, I'd not hesitate to add one of these to my collection if it became available. The chances of that happening though may be fairly slim.
One of the Top 10 Vote Getters at this years IPP design competition was the Blind Burr, designed by Gregory Benedetti and made by Maurice Vigouroux. I had the great pleasure of being able to talk to Gregory about his puzzle designs and certainly enjoyed playing with his entry in the puzzle competition, so when I had the chance to pick one up on the day of the puzzle party, I didn't hesitate.
Made from some beautiful slabs of purple heart, the puzzle measures 3.25" x 3.25" x 3.25". Each piece is cut from a solid chunk of purple heart, measuring a full inch thick, so the pieces are incredibly sturdy and finished to the high standard that is common for work from Maurice Vigouroux. Each of the pieces is polished to a high shine, and the ends of the pieces have been chamfered to really finish the puzzle nicely.
As you can see each puzzle was numbered in a limited edition of 50, and the number is stamped into the wood, along with Maurice's signature. There was a very interesting discussion on one of the Puzzle Forum's about what makes a puzzle Limited Edition, which showed that there are many definitions to many different people. It turns out that in this case it's limited because Maurice agreed to make 50, and no more! The reason why is fairly obvious when you start to play with the puzzle.
I've probably mentioned before that I'm not a huge Burr puzzle fan. There's many other puzzle types out there that I get far more excited about than Burrs. So why did I make sure to get a copy of this one. And why's it called a Blind Burr .... in my experience pretty much all Burr's are blind. Well I'm not sure I can answer the second question, but I will answer the first. And the answer is pretty simple, this is no ordinary burr!
Edit: I can't answer why it's called the Blind Burr, but Greg did. Check out the comments for the answer!
Immediately on picking up the puzzle, you find that there are three pieces which are pretty loose, and move a fair distance. Looking at the inner part of the piece which slides out you'll see it's completely smooth, so whatever burrs exist, they are only in the top 1/3 of the piece which remains hidden in the centre of the puzzle. Of course all of this movement doesn't really help much, as there is no movement at all in the remaining three pieces. Strange and definitely not an average burr.
Despite the piece on the right in the image above leaving enough space for the top piece to slide over it, that piece won't budge. Something in there is keeping it in place and there's no real hint of movement. Time to go back to the drawing board and figure out what else can move in the puzzle.
After some feeling around, you start to see that there may be another way to make progress, and sure enough that yields a little more movement in one of the pieces, and after that the rest of the puzzle will come apart using coordinate motion. It's a really beautiful movement if not particularly difficult, and well worth the time to understand.
I don't want to give too much away, as the discovery of the puzzle mechanism is a joy but you can see the seven pieces which make up the puzzle, with some familiar 45 degree blocks in there which are used in the coordinate motion. That cube was a bit of a surprise!
Putting the puzzle back together is marginally trickier than taking it apart as some dexterity is required during the assembly, and despite taking it apart and putting it back together a number of times now, I still struggle a little to get the first three pieces aligned correctly.
All in all it's a great design, and rather deserving of its Top 10 vote. All of these are currently sold, but if you see one come up for sale, grab it. It really is a fun puzzle, and even for a non-Burr fan like me, you'll enjoy it.
The Tubular Burr is a 3D printed puzzle, created by a good friend of mine Derek Bosch. The goal of the puzzle is simple. Remove the two black pieces from the cylinder and put them back. Derek kindly gave me this version when I gave him a copy of the Involute puzzle by Stewart Coffin I made recently.
Measuring 1.5" tall x 1.75" diameter it's a good sized puzzle, and as you can see from the photos, having the puzzle dyed with different coloured pieces from the cylinder really makes the puzzle pop. The White Strong and Flexible material really stands up well in the puzzle, and despite the model being hollow, there's no worry about anything breaking.
Inside the cylinder are a couple of notches, and both pieces are also notched. These notches all interact with one another inside the cylinder to make for a fairly tricky puzzle. Don't be put off by the fact that this is a 3 piece puzzle. I'll attest to it not being easy to solve. (See my later comments on that!) It total it takes 14 moves to re-assemble the puzzle so it's a good challenge.
Derek originally created this for IPP29 in San Francisco as his design puzzle entry, where it was created from sheets of laser cut acrylic which were glued together. He also used it as his Exchange party puzzle that year too. The puzzles for the IPP were created from a clear blue acrylic, however the first time I was able to play with this puzzle was with Derek's prototype "Darth Vader" version which is made from solid black acrylic. If I'm honest, I love this clear version, and can only imagine that it makes things even more infuriating as you can see everything that's going on inside the cylinder! Truly an excellent puzzle as nothing is hidden.
Derek first gave me this puzzle to play with one morning at work, and I took the pieces apart and placed all three pieces back on his desk. He told me that wasn't good enough, put it back to the way it was when he handed it to me. When I first played with the puzzle it took me around 5 minutes to take the pieces out of the cylinder, and less than a minute to put the pieces back in. When I handed it back to Derek less than a minute after he'd told me to put it back, he was astonished. I had put it back together far faster than anyone else had, and generally, he notes that it's much harder to put the pieces back in than it is to remove them.
I can confirm that having played around with the copy Derek gave me, I've not repeated this incredibly fast re-assembly, and in fact the second attempt took me a good 20 minutes to put the pieces back in! (going back to the Involute I gave him, he's still not taken it apart in over 2 months, so I think on average I'm still up - or rather Stewart Coffin is!)
Going back and resolving it several times now, it still takes me on average 5-10 minutes to put it back together, so perhaps my first attempt was beginners luck! I am getting quicker as I remember the solution but I get the feeling that leave this for a few months and come back to it and you'll still find it a challenge every time.
This is a great little puzzle, and is well worth picking up a copy if you weren't lucky enough to be part of the IPP exchange. Visit Derek's Shapeways Shop to pick one up, or one of his Maze Cubes. They're offered both dyed and undyed, and while frustrating me that I didn't solve it as quickly the second time, it proves that it's not a simple puzzle, and well worth owning.
The Wine Barrel Puzzle is a 12 piece Burr Puzzle, and another of the Puzzles I picked up while in Calico (Death Valley). This is a nicely made puzzle from Creative Crafthouse. To read about some of the other puzzles I bought while in Death Valley head here.
This is an old puzzle, dating in origin to somewhere around the early 1900's, and is an interestingly turned burr. When assembling the puzzle, the last two pieces are inserted together to form a key piece which keeps the puzzle in its barrel shape, holding all 12 pieces together. Fairly easy to take apart, once you find the key pieces, as with most Burr style puzzles, this isn't as easy to put back together, however the Creative Crafthouse version does come with the solution on a folded sheet of paper if you get stuck.
I'm no expert on Burr style puzzles, but I managed to put this back together in a very respectable 15 minutes, having left the pieces alone for a bit after dis-assembly, so it was less likely I could just remember how they came apart.
This particular puzzle is offered in two different sizes, and the one I have is around 3" high, and 3" in diameter, making this the large version. I have no idea what the wood used is, however it has a very interesting grain pattern, and makes for a nice looking puzzle.
As I mentioned, the puzzle comes apart into 12 pieces, 5 pieces are pairs, which make up either side of the barrel, and the remaining two are unique. Overall, the build quality is fairly good. A couple of the pairs of pieces aren't exactly the same size, so putting them into the solution back to front does leave a slightly misaligned finish, however it certainly doesn't stop the puzzle going together very smoothly.
On one of the larger pieces in my copy, there's a section of tearout, however again, this is entirely cosmetic, and hidden inside the puzzle, so really is of little consequence.
All in all a really nice version of this puzzle, offered for a very reasonable price. Well worth the money!
Many of you know me on a few of the forums around and about the puzzling community, and a fairly well known Puzzle Box maker, let's go with Allard's name for him and call him 'Stick guy' posted asking what I was up to. It's no secret I've bought a bunch of tools, and even started to use them to create the building blocks of puzzles, but I've never really mentioned what I was planning.
Well I answered Stick Guy's "challenge", and put up a brief summary of what I had been doing and what I was doing. You'll know if you're a regular reader that I designed a puzzle which I call Lock Cube some time back. I even prototyped it in Lego, then had it printed at Shapeways. Well at some point I'll be making it out of wood too. (At least that's the plan)
So here's where things get interesting, and when I get to the point of the title of the post. Seems like a few people out there are interested in owning a copy of my Lock Cube, when I make it.
Now at this point, many things go through my head, including a few that I can't print...
"Are you serious?"
"You really want one?"
"People want to own a puzzle I designed?"
"Is my puzzle good enough?"
"What will people think of it?"
The bottom line is that I was truly humbled by the response from quite a few people asking if I'd make a copy for them. I never expected to make more than just the one for myself, so this was a shock for me, and really left me not quite sure what to say. Quite impressive really since I've written an entire post about it!
So to everyone that has already shouted 'Me please' for a copy of a puzzle that I've not yet made from wood - Thank you.
If you want a copy, let me know. I'm not promising anything at this point, but I'll keep it in mind as I make those early copies.
