Cast UFO - Level 4? Maybe not! And Some Monkeying About.

Hanayama Cast UFO
Something has definitely changed with Hanayama recently. Their puzzles seem to have become MUCH more difficult than ever before and I am not really sure that you can trust the difficulty level on the box. I struggled with the Cast Trinity for months and months before finally solving it and a part of that eventual solution may well have been luck (I do still thank that one is a really good puzzle) and the Cast Hourglass has confounded me for several months so far and is currently locked in an almighty mess which I cannot get out of.

The Cast UFO was released in Japan a month or so ago and it has just reached Europe and North America in the last week or so ago; it is also available from my friend Tomas at Sloyd if you live in Europe. I had placed my order with Nic Picot's Hanayamapuzzles store based in the UK a good few months ago and it arrived at the Sadler loony bin on Wednesday this last week along with another rather special puzzle from Big Steve. I started playing at first with the Brass Monkey but after an hour or so it had hurt me quite a bit and I was forced to put it down and play with something less painful.

Cast UFO
Lord! These things are hard to photograph! The Cast UFO is labelled as a level 4 out of the Hanayama 6 point scale (and PuzzleMaster call it a Level 8 (Demanding) on their rather odd scale of 5-10. This one should be a nice pleasant challenge without hurting my head too much. It was designed by the amazing Finish designer Vesa Timonen who has shown himself over the years to be rather prolific.

Made from their usual cast metal, this is a lovely thing measuring 4.8 x 4.8 x 2.7 cm and looks exactly like what the Sci-Fi movies of the 50s thought a UFO would look like. There is an inner ball made from 4 equal quarters which can rotate around inside and about each other - they are slippery little buggers which makes this one really quite infuriating to play with - every time you think you might be getting close to a conformation you want, the little buggers slide out of the way. The outer part of the puzzle (saucer) is made from 2 pieces which have been painted/anodised a shiny black colour. With the coolness of a metal puzzle to the touch, it really is a nice worry bead...as long as you don't try to solve it!

It looks pretty straight-forward what the approach should be - line up the quarters with the split in the outer saucer and slide it apart. Hahahaha! You don't really think that our clever Vesa would design anything that simple do you? Slightly ashamed of myself, I have to admit that I really did think that and I spent 2 days moving the inner pieces about into different positions to try it. On several occasions, I achieved a tantalising sliding of the saucer halves and I frantically tried to manipulate pieces to allow the slide to continue. Of course, it didn't work and for a couple of minutes, I even locked it up and spent a rather panicky time frantically trying to push it back together! Eventually (after a shameful 2 days) I conceded defeat with that approach and had to do some serious thinking© - Allard would have been proud of me! The important thing to do first with this one (and you could argue that it should be done with them all) is to really LOOK at the puzzle. What do you notice that is odd/interesting? Try to look inside as well for another clue.

I had an epiphany/thought which pointed at a new approach and I fiddled around with it for another couple of days. This is one tricky little sucker. Every time you think you might be achieving something the little internal pieces swivel around and nothing is in the right position anymore. There's nothing to grip hold of and I was reduced to wildly shaking it about which never seems to work.

Whilst watching TV, I wasn't really trying very hard and just managed to achieve something new. I tried to go further by grabbing at a piece and returned it to the beginning...Damn! But now I knew what was needed and another 20 minutes later it was dismantled:

Removed the ball from the UFO
4 sphere quarters and 2 saucer halves
There are quite a few really fiddly parts to the disassembly so this would qualify as a dexterity puzzle as well as a disassembly puzzle. Having taken it apart, the cleverness of the design can be examined and then put it back together. Again, that can be quite a feat of dexterity but eventually, everything is in exactly the right place and, clink, it is a UFO again.

I would estimate that this should be reassigned to at least a level 5 and more likely level 6. It really is quite a difficult puzzle to work out what is required and also to manipulate properly - even knowing what is required, I still find it quite tough to dismantle.

All in all, this is a fairly enjoyable puzzle and well worth a place in your collection (if you are a serious collector then it is essential). If you are new to puzzling or Hanayamas then it will be too difficult - I suggest that you buy a collection from PuzzleMaster and work your way through them from easier to harder.



Big Steve and Ali Do it Again

I mentioned earlier on that I had received a puzzle from Steve which hurt me. The pair of Brass Monkeys have produced the third in the series of their brass burr puzzles, suitably called Brass Monkey 3. Those of us who had bought from them previously were allowed the opportunity to buy early and, of course, I jumped at the chance. The new version should be coming up on their Etsy store very soon and will also be up for sale in PuzzleMaster if you are located over there.

There appears to be something extra
Steve said there would be something extra especially for me in the package. I was rather excited that I might be getting something as a bonus but when the inner box was lifted out of the postal packaging, there was a small clue what had been included - Damn, I was going to have to find a way to give it back to him...maybe at the next MPP?

Oh no! I won't be able to return this one!
Mrs S was very unimpressed at the arrival of part of Steve's tongue depressor collection. Unfortunately, this one had been personalised and therefore I was going to have to keep it - if Steve makes a habit of this, however, I will have to find somewhere to put it...maybe where "the sun don't shine" and he won't be able to see it? I have a certain set of skills that come with my medical training even if I went into anaesthesia to avoid that end of the patient!

Plastic caps removed - Mrs S is very worried that I will damage the granite.
2 engraved circles plus a central hole means it's number 3 - obvious isn't it?
Allard has solved his copy and has raved about it here - he says that you should definitely get one - in fact, he wrote that many many times so it must be true! So far I have found one thing of interest and hurt myself on it! Hopefully, I will find the solution without further damage to me or any damage to the kitchen. I'll let you know.

In the meantime, you should definitely buy this series of puzzles.

Osanori's Packing - Heaven and Hell

Pack 012 - heaven
Quite a long time ago Tom Lensch was kind enough to let me know that he was going to be making another beautiful copy of the Hoffman Packing Puzzle in gorgeous woods and, being a collector who loves his wood, I jumped at the chance. When the notice that he had completed them came through and the request for a little (quite a bit) of PayPal arrived, he also said that he was about to begin making a few copies of the latest packing delight from Osanori Yamamoto that had been showed off on Facebook recently. This new one was called Pack 012 which I initially struggled to understand why it had been so named. I had wondered whether it was because of the number of cubies/voxels in the shapes but was baffled when I counted 13. Now looking at the photo above I can see that the 3 pieces are effectively shaped like an O, a 1, and a 2 - Doh!

Pack 3
Tom had made the frame from Maple with the lid and base available either as American Walnut or as more Maple - I am a sucker for contrasting woods and you can see what choice I made. I think that the pieces to be packed were made of Padauk. The craftsmanship is stunning - the angles are beautiful and the joints perfectly smooth - I adore this sort of quality. This puzzle is surprisingly reminiscent of another recent puzzle from Eric Fuller that I had reviewed, the Pack 3. This puzzle also was very beautiful and surprisingly difficult (with one false solution).

I set to playing with this straight away - the aim, obviously, is to pack the 3 pieces inside the box. It looks very simple but the diagonal hole in the corner of the box, through which the pieces must be inserted, is surprisingly restricting. I am always very suspicious of puzzles by Osanori because a large number of them require rotational solutions and I automatically start exploring and looking for any sneaky little trick that may be possible. Tom's sturdy box and accurate pieces showed no sign at all of having any room to rotate at all in anything other than the z-axis i.e. the pieces could be twisted in the box but not made to stand up or lie down once they were inside. Maybe this was not a sneaky puzzle? After about a ½ hour of play, I had found a way to pack all three pieces inside.

They are inside but this is curiously unsatisfying
After my initial frisson of pleasure, I became aware of a curious dissatisfaction. Whilst all 3 pieces have been packed, the conformation is just not elegant. One thing to realise about Osanori's puzzles is that the solutions are almost always pleasing to the eye and leave a feeling of satisfaction at their elegance. This same thing had occurred to me with the Pack 3 puzzle and after discussing it with my genius friend, Derek, I was left knowing that my solution was not the required one. Back to the drawing board.

The following day, I returned to it and, again, convinced myself that rotations were not part of it. I proceeded to try various assemblies outside of the box. Luckily with just 3 fairly simple pieces, it is relatively straight-forward to make an assembly and then work backwards through a disassembly. Derek had assured me that this one should not really tax me much and, having put aside my disbelief, I worked on it for another ½ hour. AHA! He was right - this is perfect! It is simpler than Pack 3 which seriously challenged quite a lot of puzzlers. It is probably quite on a par with the Pin Block Case - about an hour of pleasant fiddling for most puzzlers. I don't think that the picture of the solved puzzle gives too much away but I have hidden it behind a button. Only push the button if you want to see the completed packing.



The Pack 012 was the packing puzzle "Heaven" - what, therefore, is the packing puzzle "Hell"? This, my dear reader, is the Galette packing puzzle, also designed by Osanori Yamamoto.

Galette - hell
I had first come across the Galette puzzle as an entry in the IPP design competition in Paris in at which it was one of the top ten vote-getters. I had spent quite a lot of time on it in the competition room in Paris and had singularly failed to find a solution. I was delighted when Tom had offered it for sale after the IPP was completed and my copy arrived in October last year.

It looks like a simple packing puzzle with 5 tetromino pieces to be inserted into the covered rectangular space inside the frame. Again, rotations are possible (even required) around the z-axis but there is no way to stand a piece up on its edge. This is explained by the name - Galette is French for Wafer. The extra little twist to make this really tough is that the entry to the packing space is only through a 3x2 unit space in the lid or through a 1 voxel space in the lower edge. The extra interesting feature is that the bottom edge entry is part of the packing space - there are 21 voxels available and 20 voxels in the pieces - where is the gap supposed to be?

I went to play as soon as this arrived last year and after a week got quite demoralised. I put it away for a month and then tried again - nope! This went on for several months - I just could not find a solution! I became convinced that there must be 100s of possible assemblies to sift through and trial and error was required. After about 4 months I made a Burrtools file to count the assemblies - the required rotational moves told me that BT could not solve it for me, but at least I could find out how many hundreds of possible assemblies there might be.

BT worked on the challenge for exactly........1 second (on my 13-year-old computer) and told me that the space could hold the enormous number of 11 assemblies! Damn! I am really not very good at puzzling! I have picked it up again for a week or so every month and had a play - one of my issues with many packing puzzles is that I feel that there is too much random trial and error and not enough deduction in the solution challenge. Here, there is the challenge of finding the assembly and then working out how to put it in the box through the 2 small openings. I ended up taking notes on the shapes that I had tried and ruled out before suddenly finding something critical in February. I had my rather lucky Aha! moment and was left wondering why it had taken me so long. For me, this has been packing puzzle hell!

At last!
I really do not know how I did it and actually doubt whether I could solve it again! I am left wondering why it did so well in the design competition? For me, the amount of trial and error was too great. I love the craftsmanship but am not in love with the challenge.

As for trial and error, my initial approach to the gorgeous Hoffman packing puzzle has been one of frustration.

Hoffman packing puzzle - OMG - hell on earth!
The aim here is:
Fit twenty-seven blocks, measuring A x B x C into a cubic box with sides of A + B + C.
A, B, and C must be different and the smallest dimension must be larger than (A+B+C)/4
There must be a mathematical way to work out the best approach to this but if there are then it is way way beyond my skills! I guess this might take me several months or years too - gulp!

Hopefully, I might obtain a puzzle that I can actually solve soon!

Quite Simple...So It Took Me Six Months!

Two Face 3
This Man-bonic plague has continued for almost another whole week and only now is beginning to improve! I can now tell you that it is worse than She-bola as "her" suffering ended much quicker than mine and did not involve large postural drops in blood pressure which made me think I was going to die whilst I was forced to work in the garden! It is probably not a good idea to go wobbly with a length-extended hedge trimmer 2m above your head as you stand up!

Today I am going to give a much overdue review of a stunning puzzle designed by Alfons Eyckmans and produced back in October by Eric Fuller (for some reason this does not appear in his very fascinating Discontinued work archive). The Two Face 3 puzzle is a tour-de-force by both designer and craftsman as it consists of a frame within another frame and 6 burr sticks crossing them both to form a challenging puzzle with a level of 20.2.2.2.1.3 to disassemble. It was reviewed very nicely by Mike on his new blog (you really should keep an eye on his posts) and I have been meaning to write something about it since I received my copy. The problem? Not illness! This delay has been primarily because I could not solve the bloody thing!

First of all, let's discuss the joinery...the outer frame is Maple (I think) and beautifully slip-feathered for strength and then all the inner parts are Padauk. The inner frame is so perfect that it actually looks like it has been milled from a single piece of wood. The joints are completely invisible which is quite a feat. All 6 burrsticks are up to Eric's usual impeccable standard.

When first played with several of the sticks can slide and after moving a few, the inner frame can slide up and down too. There are a whole lot of possibilities and I suspected that finding the pathway to the solution was going to be a huge challenge due to multiple blind alleys. This made me shy away from it for a week or so but I left it on my pile of "currently playing" puzzles next to my chair in the living room so that I could pick it up again as the fancy took me (much to Mrs S' disgust - she thinks that pile is far too big). After a while, I thought to myself that Eric NEVER chooses to make a puzzle that is impossibly tough or full of dozens of blind ends. One thing to remember about Mr Fuller...he likes to have fun (sometimes I am sooo envious of him!) he produces puzzles that he himself wants to play with and so my initial worries about an impossibly tough burr were unfounded.

I picked it up, again, and again, and again, and again! Over several weeks I had found a very nice pathway of about 14 moves and during that discovery, it is possible to see a lot of the interior shapes of the inner frame and more mobile burr sticks. At the point where I had reached, I could see what was required...I KNEW what needed to happen next and where it should be. BUT... I could not make it happen. After a few months of trying several evenings a week, I abandoned my idea and decided that I had been wrong all along and should go back to other pathways! Eventually, I found some new moves and managed to get some more burrsticks moved and stopped. Backtracking proved a problem for a couple of days and a minor panic occurred when I thought I was going to be stuck with 2 sticks poking out! Finally, after 3 or 4 nights I got it back to the beginning again and started afresh. Still the same issue... I could see what was required but I just couldn't make it happen.

Suddenly last week, whilst feeling sorry for myself and trying to avoid the laser burning stare for coughing and "snortering" whilst watching TV, I made a new move which I should have found before - it was just a single move from a position I had found before and I had no idea why I had not discovered it before. All of a sudden, the opening I had been trying to achieve just stared at me and I could pull a burr stick out and then dismantle the rest easily. The inner frame slid out with just a nice little friction showing how perfectly made it all was - I was finally able to marvel at the workmanship and design.

Just look at the tremendous workmanship!
It only took me 6 months for a level 20!
As for putting it back together? I had not paid any attention to how the pieces were oriented or where they came from so Burrtools came to my rescue! Subsequently, I was able to dismantle it and then reassemble it all from memory and deduction - it is a brilliant design and should NOT have taken me so long! My only excuse is that I am not terribly bright!

Obviously, after such a long time, this puzzle is no longer available. It is certainly one to consider bidding for if it ever comes up at auction - it is terrific in both design and construction. Trust Alfons to design something fabulous and fun and trust Eric to choose the best challenge and make it perfectly! Thank you, my friends!

I Grille(d) This Cube...

And Found It Wanting!
Grilles II cube - looks horrific
2 types of turns
Over a year ago, the Grilles II cube was released by MF8 (I have no idea what happened to the Grilles I cube) and I bought it without even a thought! It looked hugely complex, was much more interesting than a standard Rubik type puzzle and I knew that with its' unusual turning it would be a fascinating challenge...And then I turned it a bit! GULP!

4x4 curvy dino
This stunning puzzle is effectively a 3x3 Rubik cube i.e. face turning combined with a variant of a version of a 4x4 corner turning cube, the 4x4 curvy Dino cube which I enjoyed enormously, having reviewed it not long ago here. The 4x4 Curvy dino was a great fun puzzle and pleasant to play with - it had a nice challenge to it but was not impossibly difficult and was even soothing. Any puzzler interested in Twisties should have bought it and would be able to solve it without too much difficulty. The addition of face turning moves to the challenge looked like it would add some extra work but hopefully not too impossible for a neophyte like me. I turned it a few times to see how the pieces might interact and then threw caution to the wind and scrambled the bugger! Oh boy - that produced something quite horrific!

Houston! We might have a problem!
The scrambling process is quite a long one and takes a bit of an effort to work to separate as many adjacent colours as possible. It really does get very scrambled but straight away you come across a problem with this puzzle - the pieces catch on each other very easily - especially the face turns. Initially, I thought that it was occurring because I had not properly aligned the corner turns before carrying out the face turns - it is quite possible to keep the corners aligned because the whole puzzle is very "squishy". I started working on it over a table so that I could flatten it out properly before carrying out a face turn but at this point, it became clear that the problem was not just because of malalignment. Something inside would catch the face turns almost every single time.

It was not long before the air around me went blue:

That's a whole lotta pieces!
I had an explosion over a very deeply sleeping cat who was not at all impressed at 20 or 30 bits of plastic raining down on him! A small pop very rapidly ends up as a very major explosion. Then, having been scrambled, it is not just a matter of stuffing the pieces back in any old place - that is a way to end up with an impossibly assembled puzzle - a full disassembly is required. On several occasions, I actually lost one or two of the pieces in the crevices of my chair and thought I had a defunct puzzle.

I could not find any plastic flashing as the cause of the catching and explosion - rather I think that the corner pieces (which are assembled from 3 separate pieces) are not tightly held together and so anything which puts any stress on one side or other can make them fly apart and then the forces holding the rest of the pieces have been removed...BANG! The reassembly is not a trivial event either! This puzzle is extremely unstable until more or less the last piece has been inserted. If you attempt this then you WILL require tape - I find that light surgical tape is perfect.

Build it up section by section and tape them in place
Having successfully assembled the puzzle, it was time to scramble again...BANG! Oh Lord! Not again! A second reassembly and I put it aside for a few months to calm my nerves!

It remained stored as a potential puzzle to try for many months and I picked it up again a few months ago and scrambled it. As with a lot of puzzles which appear to be a more complex version of something already in existence, my aim would be to reduce it to one of the base puzzles - in this case, I would attempt to reduce it to a 3x3 which I could then solve as a standard Rubik cube.

As with most corner turning puzzles that are not really deep cut (like the Skewb), movement of the pieces around the edges is fairly trivial and usually can be done with the ever-helpful up, up, down, down combination. I started pairing up the larger parts of the edges - that would be pieces like the red and blue piece at the bottom of the picture above. This was very similar to solving a standard 4x4 - make the edges and then store them out of the way - easy until you have just 2 or 3 left but definitely a fun challenge. At this point I found I had a surprise:

All double edges are paired up and placed
BUT the red-yellow and opposite orange-yellow pairs need to swap
I had 2 pairs of edges that needed to be swapped. Nothing I tried would work - time to THINK©...It took me a week to sort that one out! It was time to solve the centres of the edges - using my standard up, up, down, down moves with setups too and all was going well. Or so I thought...

All the edges are done but I had 2 swapped
Again, this stumped me for a week! THINK© again! This time I had to use the up, up, down, down rather creatively and several times. Not on the small edge pieces but to reverse the entire direction of an edge. It is a standard series of moves in the "Ultimate solution" and rather fun to have to use it here. Finally, just the outer edges to move about and BINGO!

The puzzle was solved after just 10-11 months! Most of the time it was sitting on a shelf or in my bag waiting to be solved but a fair bit of time was thinking©. Time to try again and Boom! I had pieces again. Laborious reassemble and after calming my nerves TRY AGAIN. Solved it! Yay! A third time and oooooh! What is this? Another unexpected event - a single corner turned:

Nice corner parity!
Luckily this was not terribly hard to fix - if you remember the Dreidel cube (ecstatically reviewed here) then a similar event can occur with that and the solution is the same - it's not tough - just needs more thought.

I usually try to solve a puzzle 8-10 times to prove to myself that I have mastered all nuances of it but this I probably only managed 5-6 solves of this - it just kept exploding on me! For this reason, I have to come to the conclusion that this is a very nice puzzling challenge but definitely NOT one I can recommend to most puzzlers. It is just too unstable and the reassembly is neither trivial nor fun. If you are a collector then go for it and just be very careful when you play with it - you will enjoy the challenge of the solve but if it catches in any way at all then just stop and backtrack and realign before trying the move again. I am pleased that I own this puzzle and have solved it but it is going back in storage and is unlikely to ever be scrambled again.

Part way through my solution of this one, I did think there was a remarkable similarity to a puzzle I bought from Chewie's Custom Stickers, the Corona cube:

Corona Cube
As you can see it is an edge turner and a corner turner - only one level of corner cut and the depth is different - it was fun to scramble this one and see how it compared:

Very similar cuts but not quite the same - how would the solve be?
The puzzle was FDM printed and took quite a bit of effort to move and hurt my hands a bit in the process but at least there was no popping.

A nice challenge
The Corona cube was easier to solve with fewer pieces but very stable. After a couple of solves, I put it away as my hands were killing me. I still have a few more twisties awaiting my attention but they scare me to death! Plus after the Grilles II cube, we are all exhausted!

Wow! Dad! I need to lie down after solving that one!

Assembly of Puzzles - a Toughie but a Goodie

Puzzle Splines
It's a bank holiday weekend here and I am really not up to much! Sniffle! Cough! Splutter! Groan! Yes! I have Man-bonic plague! Today's blog post nearly didn't happen. Not because I have been feeling like death for over a week now (I did manage to go to work and infect a large proportion of the operating theatre staff) but because I managed to infect Mrs S too and it mutated into something much worse...She-bola! As a result of this plague in the Sadler household death nearly did visit me in the form of a vengeance-seeking woman! Luckily I am just fit enough to evade her grasp/knives/lasers!

Today, I am focussing on some assembly puzzles that have finally fallen to my feeble skills recently.

The puzzle above is the latest offering from Michail Toulouzas - offered by my friend Bernhard Schweitzer. It is the Puzzle Splines which is a relatively new idea from Michail. It was offered either in Sugar Maple with Pink Ivory splines or, as in my copy, there were a few made from Wenge with the Sugar Maple splines. I cannot resist contrasting woods and chose this. It is pretty big at 11cm across and forms effectively a cube with triangular outcroppings from it. It certainly is stunning and quite heavy.

I initially thought that it would be a kind of disassembly puzzle and one at a time pushed at the vertices and saw that they could be slid off the cube:

A couple removed
6 different splined corners
So far this has not been too puzzling - the remaining cube is rather rattly and I realised that this could also be separated into pieces - not easily, however - there seemed to be a little coordinate motion and twisting required. Should I take some notes? Draw some diagrams? Nah! I'm far too sick to go hunting for a pencil! I wanted to stay sitting down and keep going. I soon had 3 more pieces:

Yay! An assembly challenge!
Even in my totally befuddled, drugged to the eyeballs state, I was able to see a few of the possible assembly patterns of the basic frames and managed quite quickly to assemble something that had an interesting position of the splines that even I could tell was impossible to assemble the remaining corners on. Back to square one. Luckily there are only so many ways to assemble the frame and on my second attempt, I found an assembly that worked. I had solved a puzzle under the influence of a very strong cold remedy...maybe I should solve all my puzzles that way?

Flushed with success at assembly, I threw caution to the wind and climbed the arduous mountain of (13) stairs in my house to the upstairs puzzle room and retrieved the Kubikub 2 puzzle that I had bought a few months ago from My lovely Turkish friend, Yavuz Demirhan. He sells his puzzles through his Etsy store which is well worth keeping an eye on for future updates.

Kubikub 2
This is a pretty simple design consisting of a gorgeous Wenge frame and 3 sets of double conjoined cubes made from Padauk intertwined inside and flush with the surface of the frame. The puzzle is not as simple as it would initially appear as it requires 13 moves to remove all 3 pieces from the frame. When I first received the beautiful puzzle, I fiddled a bit and realised that the disassembly was not going to be the challenge - I could remove the pieces pretty easily and then having learned the moves and preserved the orientation of the pieces and frame, I knew that reassembly at that point would not be terribly tough. So it went back on display until I was ready for a proper assembly challenge:

How hard can it be?
I scrambled the pieces for the photo and left them a few hours whilst I lay down to feel sorry for myself. An hour later, feeling not in the least bit refreshed having drowned in mucus, I set to work on the reassembly challenge. I realised at this point that the frame is not symmetrical which makes this a considerably tougher challenge. Idle random moves hardly ever solve a puzzle in my experience and they certainly didn't do it this time. What they did do is show me that there were only a few positions of the frame where both ends of the double cubes could be flush with the surface of the frame. Then it was a matter of working out where it would be possible to arrange all three of them so that they could be flush. I was on my way - actually being logical! Not at all like me...these are damned good drugs!

It took me another hour to find a very fun little sequence where the first 2 of them would fit in place and then how to move them in such a way as to accept a third. Yet another assembly puzzle solved despite my feverish brain. I should get sick more often - what am I saying? Ignore that!

Finally - I went back to a puzzle that has kept me busy for nearly 3 months - Goodie! Yes, it really is a goodie!

Goodie from Stephan Baumegger
Goodie was an unexpected gift in the package from Stephan when I purchased the incredible Hydrant puzzle (reviewed here). It had been Stephan's exchange puzzle at the 38th International Puzzle Party last year in San Diego. He had designed and made this one from Zebrano and was rather pleased with it.

I, of course, was also delighted! I had an extra unexpected puzzle! It was gorgeous, made from beautiful wood and looked like a nice but not too tough challenge:

7 pieces to make a 5x5x5 cube
How hard can it be?
This is a dissection of a 5x5x5 cube with only orthogonal cuts and I was sure that it would not be terribly hard. Lord help me! How wrong I was! I sort of got a hint that it might be quite tough when, having taken my photos of the pieces, I tried to put them back into the box for transport to and from work with me...I couldn't get the bloody things back into the box and close the lid! Am I really that rubbish? Erm...yes! Sob! I took it to work a few times in a bag because, to my eternal shame, it took me a month before I was able to pack the box properly!

There are some rather interesting pieces which scream that they should go together - and I dutifully fell into Stephan's trap:

2 mirror image pieces
They slot together like this
Having got myself fixated on this I worked on this puzzle many evenings for 2 months. I did try a few other ideas but I was getting nowhere and was starting to suspect that Stephan was laughing at me. I must have spent many many hours on this getting nowhere but always going back to those two pieces that fit together so well. In the flush of my success from the other 2 puzzles above, I decided it was finally time to solve this bloody Goodie/Baddie! Another hour went by and another and I began to tear out the last few strands of my remaining hair when suddenly I had an epiphany! OMG! Aha!

You sneaky b.......! How could I have been so stupid? Scrap that! I know I am stupid but how can I have been so stupid for quite so long? Aaargh! Only the drugs helped me solve it - I need more!

Finally!
It's a Toughie but a real Goodie
If you get a chance to try this puzzle then jump at the chance!

Have I finally cracked my inability to solve assembly puzzles? No, I don't think so. My brain has been altered by a befuddling virus/plague and then further addled by some very strong medication - I seriously do not recommend puzzling on drugs!

Now, what shall I work on next? I am far too sick to go outside and partake of the peculiar British habit of gardening on a bank holiday weekend! I need to stay indoors and exercise by lifting small cubelike structures.

I should also sit down with Burrtools to put this thing back together - it has been sitting in pieces on my desk for 10 days!

Terrax has lots and lots of pieces!

Robert Sends a Twofer Which Scares Me!

The Incredible Stickman Dwemer Construct Puzzlebox
Well, here I am running late! Mrs S has been away most of the week visiting the outlaws and, as is usually the case, she times it for just when my workload goes through the roof! I think she does it on purpose! Instead of having plenty of time, home alone, to play with all my toys and write a nice blog post, I have been up to my eyeballs in work and even spent all day yesterday writing our on-call rotas! I only just finished up this puzzle this morning after doing all the chores that "she who scares the bejeezus out of me" had set for me to do before she gets home.

Yes! It's a box! And No! I was not tricked into purchasing it! My cardinal rule is if I have the opportunity to buy a box from Stickman (aka Robert Yarger) then I just hand over the cash! Mrs S doesn't know that but let's not tell her, shall we? This particular box was offered out quite some time ago and it took Robert a good bit longer to complete the design and make the batch than expected. The wait was more than worth it! It really adds something to my little collection:

My Stickmen (including a Stickboy and a Stickman apprentice) - plus a few other beauties.
The Dwemer Construct Box is named after an ancient lost race in the Elder Scrolls, well known for their skills in crafting mechanical items.

This incredible construction is big...REALLY big and pretty damned heavy too. It has a handy top rail which is perfect for carrying it about. Every time I played with it I lugged it out of the display cabinet and then put it back after I had got stuck - Mrs S would not tolerate it being left lying around in the living room!

Looking at it closely it is clear that a huge amount of work has gone into it and pretty much all of it is crafted from wood with only a few well place brass screws holding components together. Lots of things turn and can interact with other pieces in mysterious ways. Not all are visible either - requiring a fair bit of deduction/guesswork during the process. It is very quickly apparent how the lid is attached to the box and what is required to allow that lid to be removed...the issue is making it happen! None of the appropriate parts are able to move in appropriate directions as they are blocked by other parts of the puzzle.

I worked on this, on and off, for a couple of months and kept getting stuck. They always come with a wonderful spiral-bound booklet but I try not to use that unless absolutely necessary. My stubbornness has left my Stickman Perpetual Hinge unsolved for more than 5 years! There are four phases to the solution of this puzzlebox and I got the first within a day or so. Step 2 took me over a month and then the others the same again. Some of the moves require a bit of a leap of faith..."Am I really supposed to be able to do that?" Eventually, (yes I did peek at the booklet just once) I had the release mechanisms all aligned correctly and I gently lifted the lid off to see why the puzzle had been making so many rather loud rattling noises whenever I picked it up and moved it from display to living room:

Inside is a bag of bits - including a screwdriver!
I said this puzzle is a Twofer! Robert did us proud with this one and this explained the delay. Not only do we have a beautiful large complicated box to solve but we have all the pieces inside to construct a second challenge - "two fer the price of one"! In fact, this was very nearly a "threefer" - he has ideas for another challenge but did not have time to make it - it is possible that the third challenge is made available sometime in the future (obviously we all expect to pay for it if it happens). After the solution to challenge one is a rather startling page in the booklet:

OMG - I'm gonna have to be brave!
This morning I spent a happy hour or so playing with my bag of bits and the screwdriver - this left me with a rather horrific worksurface with even more bits than I would have believed possible:

OMG - I have locked the cats out of the room! I can't afford any mishaps here!
The quality is simply stunning - everything is so perfect. The instructions for the disassembly and new assembly are step by step and quite easy. I have a small issue with an alignment of one piece in the new challenge that I am waiting for an answer from Robert but I suspect I have made a schoolboy error.

Even seeing the construction process for the second challenge amazingly does not give away how to actually solve it! I know how some of the pieces interact but have no idea how to open the box.

Probably another 3 months to solve this one!
I'll keep you informed of my progress through challenge two.

Now Mrs S has just arrived home from Edinburgh and I had better finish this and pay her some attention - if I don't then we may not make it our 25th anniversary and I won't be allowed to keep the Berrocal Goliath that is my present for lasting so long. Plus, I actually think I could do with a little bit of relaxation for the rest of the weekend - what little is left!

Rex Makes it Super Complicated

.......And Beats Me!

Kusing 25
I have now received 2 of Rex Rossano Perez' wonderful puzzles as gifts now. I wrote about the first one which was given to me by my friend Ali and Rex himself here in September last year and then another 2 of them which I bought from Rex here. They are beautifully made puzzles cut from Acrylic and the common feature is that there is always a Filipino coin inside needing to be released by some mechanism or other - it may be a maze, a sequential discovery puzzle using tools provided or a sequential movement/sliding piece puzzle. I successfully solved the first 3 and was terribly chuffed because the internal mechanism of these is pretty complex. On Facebook Rex has designed and produced (in limited numbers another bunch all with a similar theme and I am quite keen to try out some more.

The Kusing 25 was another gift from Rex and after a very long trip around the world, it arrived in early March. After the obligatory photos I set to playing with it and within a few moments dropped a tiny piece/tool out onto the cats head and lost it down the side of my chair cushion. After a fair bit of cursing, a scratch from the unimpressed cat, I retrieved it and had a look to see where it came from and what I had done to get it to come out of the tiny hole. Much to my chagrin, I was completely unable to put the piece back into the puzzle! The hole from which it had dropped had closed over and nothing I did would allow it to be reinserted! You can see where this tale of woe is going, can't you?
Having failed to backtrack, I decided to continue puzzling and see what could be achieved by using that tool in the two suspicious looking holes in the bottom of the puzzle.

As if invited by the designer, I inserted the tool into one of the hoes and twisted randomly...nope no change in the puzzle. On to the second hole and suddenly the slider was able to move back and forth. Twisting around I could stop and start the slider moving and at times was unable to twist the tool anymore. I played with this for a whole evening and nothing seemed to be happening! On evening 2 I persisted in my random fiddlings and noticed that despite keeping the tool rotated in one place the slider seemed to sometimes move and sometimes not move. At some point during this, the coin was suddenly able to move inside the puzzle - I had absolutely no idea why!

Manfully, I persisted in further random movements for several days and, all of a sudden, the coin dropped onto the cat! YAY! I think! It was solved! Except it really wasn't. A puzzle is NOT solved until it has been done, undone and done again. The important thing is to understand how it works - I wrote about this here and here. It was time to try and reset it back to the beginning and try again - GULP!

Solved it! Except I hadn't really! No idea how I got this far.
I have spent the last 3 weeks trying to reset this blasted puzzle and somehow managed to lock the coin back inside without understanding how but could not get the coin locked under the window and certainly not get the tool to stay in its small receptacle. To my eternal shame, I ended up undoing the nuts on the puzzle and gingerly pulling apart the layers!

OMG! That is an incredibly complex and clever mechanism! I am absolutely amazed that I managed to remove the coin by accident. It took me about a ½ hour to understand all the steps and then another hour to get the pieces all back into position! Damn! That takes some dexterity!

Starting with a fully reset puzzle, I went through what I thought was the correct set of moves and it seemed to be working when suddenly a new piece fell out! That wasn't supposed to happen! Back to pieces it went and I saw my silly mistake and this time it was a functioning puzzle.

With the benefit of hindsight/maliciously dismantling the bloody thing, I am now able to retrieve the coin almost at will and then put it back. The toughest part of it is the reset - getting the tool back into its little hole.

This is an amazing and complex sequential discovery/sequential movement puzzle which really beat me and is well worth obtaining if you can. Don't expect to beat it quickly or easily!



Alfons Beats Me Too!

Kalinka
I am completely addicted to interlocking cube puzzles and I could not resist buying another 5 of them from Alfons Eyckmans. Apart from having very little time to play, I have worked on several of them and not gotten very far. Yesterday I had an hour to spare and Mrs S allowed me to play with one in peace. Eventually, I produced my lovely pile of pieces and created a Burrtools file! Unfortunately, I cannot put it back together unaided!

Lovely pieces!
My computer has been trying to find the solution and after working for 16 hours so far is nowhere near a solution. It just recently announced that it might take another 1.2 years which is probably more time than Mrs S will allow me to have a pile of pieces lying around! My iMac is 12 years old and kinda struggles with complex tasks!
