A Fun Week Of Torturing

Ice Cream SandWitch
Having had a bad week last week, I was really motivated to get back into it for this post. I took the three TICs that Allard gave me to work and tortured a couple of lovely girls who surprised me with their tenacity.
Georgia - my ODP
Even the radiographer!
Caduceus pieces
I had worked on Caduceus first after writing my post last week. It looks the easiest of them having only 2 pieces to fit inside. The fun thing about it is that both pieces have circular rods in them which implies that they will both need to undergo rotations to get them placed.

The first thing to do is go through some thinking© to work out which direction each of them need to be placed across the cubic frame. I was gratified to see that both girls who tried this puzzle did exactly the same thing before attempting the insertion. It's nice to see that thought is universal with puzzles. 

Having established the direction of travel we experimented to see how the individual pieces could be moved into place and then see whether the second one could be manipulated around the first. Oh boy! They really get in the way of each other. There are a LOT of moves and they dance around each other a huge amount. There are so many rotational and sliding moves that for me it is impossible to keep track of them. I managed to assemble it last Sunday evening and then couldn't take it apart again for a very long time.



Eventually I separated the pieces and watched in fascination as Georgia and one of the other theatre staff worked on it and was very gratified to see that they had the exact same experience. Both really enjoyed it and were keen to try the others. I love infecting others with the excitement of puzzling! Especially girls - we need more girl puzzlers.

The next 2 of the TICs from Alan Lunsford were Cobra and Hydra:

Cobra has only one rotational piece
Hydra has 2 rotating pieces
Cobra has the advantage that the two frame pieces are just like simple interlocking cube puzzles and relatively easy to work out where they go together but then whilst it is simple to see where the rotating piece has to go, it is actually a huge challenge to insert it into position. With everything you try the piece almost arrives but not quite. Many possible moves leads to the thing falling apart. None of the girls managed to get past this point and it was with some trepidation that I attempted it myself. It is damned tough. There is a very very nice sequence to get the thing assembled. Luckily with this one, once you have done it then the disassembly is not going to be hard to manage. It is really clever and perfect to get someone hooked - the ability to get so close and yet so far away is wonderful for the experienced as well as the newbie puzzler.

Hydra has 2 rotational pieces and it doesn't take long to work out where they have to go. Like the Caduceus, there is a whole lot of dancing with some rather extreme moves before it eventually slides together. Disassembly is also a challenge. It took me a good hour before I could say that I really understood the puzzle. I will be taking it to work to torture people for a few weeks.



If you have a 3D printer (Sob! Never me!) then I suggest you go to Alan's Printables page and download the files for these and make yourself some TICs - they are simply fabulous!

Next up, I tortured myself with George Bell and Nan Ma's Dodecahedron assembly kit. I spent quite a lot of time in the IPP design competition room in Italy attempting several of the challenges set out with these and completely failed. I came to the conclusion that my hands are too small or the pieces were too perfectly made with not enough gaps to help me. But, I am a sucker for a puzzle kit and the five challenges sung to me. I started with the easiest of them (rated medium) and after nearly an hour yesterday, I finally managed an assembly. Hooray!

Dear Lord! That was tough and it was the easiest!
I spent another couple of hours trying various of the other challenges and got absolutely nowhere apart from to teach the cats some swear words and to piss off Mrs S with all the muttering under my breath. The pieces can be assembled gradually by gently pulling apart and adding extras. This continues until there's no space for any more and then as long as the assembly is correct there's a space for the final piece but no way to insert it. Time to take a few out and place them in a different order. Finally you have to pull it apart to the almost falling to bits position and try and manoeuvre the last piece or pieces and let it collapse together into shape. Unfortunately, I have been completely unable to manage it - I pull it apart to the almost falling to bits and then as I wiggle, it just "falls to bit" - Aargh! I'll keep at it for a while longer but I'm losing hope. I saw a friend at the MPP manage them all but I have no idea how.

Finally I have to show off the Ice Cream SandWitch puzzle which I also solved this week.

Ice Cream SandWitch by Alexander Dangl
I never noticed the mis-spelling until now!
This puzzle was also an entry into the Design competition this year where it won a Jury Honourable Mention Award. I actually didn't play with it myself at the IPP because I had immediately decided that I wanted to buy a copy having seen p[eople enjoying it and with lots of shouts of delight as they solved it. The following day at the main puzzle party, I quickly found it for sale and got hold of a copy. Let me say straight up - it's a lovely thing and great fun to solve with plenty of Aha! moments.

It is available in 3 ice cream flavours (pistachio, vanilla and the strawberry that I have). The aim is to work your way through finding and using tools to get yourself the coin to allow you to buy more ice cream. At the moment it is available from PuzzleMaster and sold out at Tye and Amanda's Nothing Yet Designs (they may well get more n stock in time).

Initially, the only obvious tool is a bolt that slides part way out when you tilt the puzzle downwards. The first thing to do is work out how to release the bolt and then see where it can be used to make other things happen. The first couple of moves are quite easy to find and will lull you into a false sense of security. I managed those first couple of steps very fast and then got stuck for a while. I had a bolt, a magnet and that was it. There are lots of magnetic areas inside the puzzle but I was unable to manipulate them. I had to put it down for a while due to demands by the present wife that I do some stuff for her. Later on, I returned to the puzzle and noticed something really quite subtle. Aha! I now had...another magnet and nothing to do with it.

I'll not tell you what I did next as I don't want to spoil it for any of you but I have to say that you need to use physics to solve this one and after another few moves you have your coin to allow the purchase of more ice cream. It's wonderful and certainly a candidate for my top ten(ish) of 2026. I will be bringing this to work to torture people as well. My work bag is always shoulder bruisingly heavy because I bring so many great puzzles with me. Torturing people is fun!

A 3D Printer Is NOT Allowed

Thank Goodness I Have Puzzle Friends!

Dodecahedron Assembly Kit by George Bell
Printed by Allard (thanks mate)
I am absolutely amazed - my post views have passed the 7 million since I started writing in March of 2011. Thank you for reading my crap!
 

After the last 2 weeks of desperately trying to solve the upcoming Pelikan puzzles as quickly as I possibly can, I have been rather fatigued and not actually done any puzzling at all this week. So I don't have anything to really review today. I did attend the MPP number IIXIIXIIXIIXIIXII yesterday (yes that does seem to be a Roman numeral! Allard needs to remember the number L for simplicity.) and one of my favourite things when I go there is to pick up a bunch of plastic freebies that Allard and other friends have produced for visitors to take home.

I have a rather big birthday coming up soon and I had hoped that maybe a Prusa or Bamboo toy-maker with all the multi-colour trimmings might be a possible gift from she who frightens the Gods - I even suggested it to her (Whack! Ouch!) However, the present Mrs S is very frightening. She has said on numerous occasions when I mention a possible purchase, that the arrival of a 3D printer in her house (NOT mine) is definitely grounds for divorce and I really cannot afford a divorce! This means that it's absolutely NOT happening, no matter how nicely I ask. No, she is not worried about noise or electricity usage. Her primary reason for the absolute moratorium on this wonderful technology is that she is aware that the profusion of wood and metal "stuff" that keeps arriving and cluttering the house will rapidly be supplemented by a huge bunch of "ugly plastic crap". Modern 3D printers produce stuff that is much less ugly now but she does not want yet more puzzles arriving courtesy of the printer. Sob! Luckily, I have wonderful friends like Allard, Rich and Dan who can make 3D printed puzzles which I can smuggle in without risking life, limb and sanity. Oops! Sanity went a very long time ago.

One puzzle set that arrived yesterday courtesy of Allard was George Bell's incredible entry into the Assisi IPP design competition. Whilst it didn't win an award, it was a fabulous challenge which I spent quite a lot of time on. Interestingly, I had almost no success. It is a series of coordinate motion challenges and I left Italy rather frustrated thinking that it was impossible for someone with relatively small hands. I do tend to pride myself on having fairly decent hand control and dexterity (on Wednesday I had to put a cannula in a vein on the front of a patient's shin under ultrasound guidance!) but I really struggled with it. At the MPP the puzzle was attempted by a few people and even the most difficult combination was assembled successfully. I now have the option to try them myself in the privacy of Puzzlemad HQ without anyone laughing at me with every failure.

Another advantage of a 3D printer is that all the wonderful new TICs that get designed can be quickly added to a collection without having to wait for a craftsman to make them in wood. I adore TICs and interlocking puzzles. Allard had 3 new TICs from Alan Lunsford sitting to be taken home. They were smuggled into the house with my MPP box and secreted quietly where she can't see.

Caduceus
Cobra
Hydra
I can't wait to work on these. 

So, in the absence of my own 3D printer I will be "forced" to attend MPPs so that I can endure being made fun of but still manage to pick up plastic toys without being told off. See you all at the next one.

A Jigsaw But Not A Jigsaw

Jigsaw Box by No Problem Puzzles
Kumiki Crane
It has been a busy week at PuzzleMad HQ. Despite the catastrophic loss of the orthopaedic cement supply to the National health service, I had a very full week of operating and then lots of meetings to attend. This was then followed yesterday by an MPP (I am sure that Allard will write this up soon) and today by a fun episode of DIY. Someone has decreed that the compact fluorescent tubes used in my under cabinet lights in the kitchen are no longer available in all the sizes I need (one had blown last weekend). Mrs S decided that it was necessary for me to replace the light fittings completely so that she didn't chop any fingers off whilst cooking. Today, I have failed to electrocute myself, which is a bonus, but spent a good 3 hours with LED fittings, wires and junction boxes. Mrs S is now happy (phew) but it does mean that I have actually not managed to solve anything complex this week (apart from a bunch of Karakuri puzzles that I managed to get my mitts on at the MPP). My unsolved puzzle backlog is epic!

I did come home from Birmingham yesterday with a couple of freebies. The Jigsaw Box designed by Theo Geerinck and the late Symen Hovinga and a Crane puzzle rather reminiscent of the origami flapping birds that I used to make as a kid (I can still remember how to fold it).

Whilst relaxing in front of the TV with Mrs S last night, I took the crane apart and scrambled the pieces. 

Quite lot of small parts to fall down the sofa
Once I had left it for a while I attempted the reassembly. I didn't think it would be terribly tough but Mazikeen was very intrigued by the small green pieces. She would not get off my lap and would not stop pawing at them. At one point she grabbed a wing and ran off with it 😱. I really don't want to have a partially assembled puzzle and even more didn't want a trip to the vet for removal of puzzle piece from cat intestine. So ensued a hilarious romp around our conservatory as I chased the puddy tat behind the sofa and out the other side before retrieving the errant piece. The reassembly took me another 20 minutes due to constantly dropping pieces whilst preventing the minx from running off again. The assembly, once completed was a nice rewarding challenge and requires a little thought to ensure that the key piece actually locks in place. Thanks Allard.


Next up, the Jigsaw box. 3D printed with 4 identical walls to the box and a lid and bottom. the walls can slide onto each other sequentially but this leaves the top and bottom of the box blocked. It seems impossible to place them. Time for a think© and it quickly becomes apparent that this little challenge is not a Jigsaw. It's a coordinate motion puzzle. I was kind of hoping that I might have more luck with this than the last coordinate motion puzzle that I picked up at an MPP!

This six piece puzzle from Stewart Coffin remains in pieces!
Luckily, the jigsaw box is only a little bit fiddly and doesn't require 4 hands and the ability to reverse gravitational fields. After a few minutes, avoiding the cat and jiggling pieces about to the right position and then pushing them all into place simultaneously, I had my Jigsaw box:

Strangely satisfying!
Hopefully this week will give me a bit more puzzling time.

Triforce From Hanayama

Hanayama Triforce
Just a very quick review today. At the last MPP, I got the opportunity to buy (thanks Steve) all three of the latest Hanayama Legend of Zelda related puzzles (Triforce, Hyrule Crest and Master Sword). They do seem to have increased in price considerably compared to the other Hanayama cast puzzles, presumably there is a premium that the Hanayama company are having to pay to Nintendo for the rights to use those names and the imagery that goes with it. Whether the extra cost is worth it to you will be something that you have to decide but, let's face it, most of us are completely addicted and cannot really resist a new one and, in the grand scheme of our puzzling habit, these are really relatively cheap. 


The Triforce has been rated with a difficulty level of 5 out of 6 by Hanayama and, by PuzzleMaster, as 9 (gruelling) on their odd scale of 5 to 10. I must say that I completely disagree with these ratings. I would place it as a 2 out of 6 or 6 out of 10 (PM).

The puzzle is quite attractive made from 2 colours of matt metal (brass and pewter colour) and looks like it has been aged. The puzzle is a diminutive 6.2 x 5.3 x 1.2cm and feels well made. The Zelda Royal Hyrule Crest insignia is on the front of the centre piece.

Obviously, the aim is to separate all four pieces and then put it back together again.

Initially, when playing there is absolutely no movement at all apart from a very slight wiggling of the pieces which might give you a hint of what is supposed to happen. At this point nothing else is possible. With a little "manipulation" there suddenly is more possible and then you seem to be almost there. Almost...but not quite. There has been a good amount of sliding as the description mentions but the pieces are still locked together. Thinking© further along the lines of what was the initial move will quickly have you separate the pieces. The picture of the pieces doesn't really spoil it but I have hidden it behind a button.


Having scrambled the pieces for a while then reassembly takes a little thought to work out what orientation and position everything should be but not a huge amount. I did find for a few days that it made a rather pleasant worry bead to fiddle with. This one will not give any seasoned puzzler much of a challenge (do please ignore the difficulty rating) but it is another one for a collection and is a nice one for newbies. The Zelda theme may attract a bunch of non-puzzlers to try it and maybe they will be hooked in our hobby too.

Octaballs - Never Look A Gift Horse In The Mouth...

It Might Bite You or Poke You or Frustrate You!

Octaballs by George Bell (kindly made by Allard)
At the beginning of the year Allard reviewed a nice little bunch of puzzles that he had made based on some new designs by George. He called them "diabolical" and I was intrigued. I have lusted after a full set of the Pennyhedron puzzles from the ever so slightly warped Australian dentist Stephen Chin (Ok he is more than slightly warped!) but have never managed to find them at a reasonable price and Chinny keeps threatening to fleece me when I have talked about buying them. George worked with Chinny on many of them and more recently has expanded the geometry to include a hybrid shape between an octahedron and a ball - hence the Octaball. I think there are quite a few new interlocking designs that he has found.

I commented on Allard's page that I am not allowed a 3D printer (apparently, I am told on good authority that arrival of one of these "terrible addictive devices" is grounds for divorce). I was thinking about asking George if I could buy a set from him when Allard let me know that he had made a second set and would let me have them. I thought that it was terribly good of him to preserve my marriage like that. They arrived in mid January and I had a look and admired the lovely materials that had been chosen for the printing. They have really improved over the years. Allard had bundled them all into a ziplock bag all together but had given me a list of the numbered pieces which belonged in each puzzle.

Later that week, one evening after work, I set to attempting the first assembly. I picked one at random. I couldn't work out which was going to be the easiest and chose the first with all 4 identical pieces. It is pretty easy to assemble the first 3 into the shape and can see how the last one will go in. Putting the bloody thing in, however, is another thing entirely! These things have teeth or pointy bits. As you probably know, these are coordinate motion assemblies and I am really not great at that sort of thing. You would think that with what I do for a living, I might find these relatively easy. Except that by and large, I don't do things that require multiple hands holding things in precisely the correct precarious position. I spent an hour attempting to assemble this first one and failed with a lot of swearing which upset Mrs S almost as much as the purchase of a 3D printer. I moved on to another one which had 4 different parts. There is no difficulty working out what goes where but actually doing it was really really tough. I failed on all 4 of them that night and for a little while had a sore thumb where I had managed to lever a pointy bit under a thumbnail.

Tyler had chimed in on Allard's post and had concluded that no human can assemble them without assistance from another helpful human and I was beginning to think he might be right. Allard maintains that Gill did not assist him but who trusts what Allard says about anything? I looked around the house to see if I could find a "helpful human" and there does not appear to be one of those living with me - I was doomed to fail, suffer sore thumbnails and swear a lot before receiving the laser stare and even a Whack! Ouch! On evening number 2, I juggled all the pieces using a hand to hold them and a thigh to prevent a piece falling out whilst I introduced the final piece and Aha! I had a result.

Over the next two evenings, I managed to assemble 3 pieces in, extend the coordinate motion out as far as possible whilst maintaining stability (with a couple of them, I had to work out which pieces were the best for this extension). Then I used various parts of my anatomy as a third hand/stabiliser as I extended beyond stability and finally introduced the fourth piece. I quickly realised that using my nose as a stabiliser was no use as I couldn't then focus close enough to see to introduce the next piece. Thighs seem to work best and one time the top of a sleeping cat's head did the trick. It took me over a week and I had some assembled Octaballs:

Phew! That was a bugger!
These have been sitting on my desk all assembled and looking lovely since then. Unfortunately, I have to chair several MS Teams meetings every month and having a nice big screen at home means it is better to work in my study than in my office in the hospital. The trouble with that is that, I have these lovely big worry-beads just a foot away from me whilst I chat to colleagues. I cannot help myself - I often pick them up and find it quite relaxing to gently start the coordinate motion off and slide them back and forth. Except...

A bloody cat jumped on my lap during one meeting frightening me half to death! The Octaball in my hands that was partially opened flew out of my hands and sprung apart on the floor. In my and his surprise, he shot of my lap and knocked another onto the floor disassembling it as well. The horror on my face was visible to everyone in my meeting. It may have been even harder to assemble them a second time! Aargh! They have been put away in one of the bookcases to prevent this happening again. 

Another gift horse came from Neal. When I bought the set of Dessert TICs he added in a couple of gifts to the package that he had 3D printed. Again, I am not allowed one of these and so I can only ever get these from other people. I reviewed the wonderful Screw burr in May and loved it. Also in the package was a copy of Screw Fit by Oskar:

Screw Fit by Oskar
It has also been beautifully made and is lovely and bright. It consists of a ring made of 4 pieces held inside a nut. There is nothing for it other than to try and screw the nut off the ring and it becomes immediately clear that odd things are happening. The different pieces move in all different directions until they suddenly fall out - OMG!

That wasn't very bright of me
After my initial pleased exclamation, I put the pieces in the bag and left it for a few weeks to try and forget the way they had been assembled/disassembled. 

I was able to work out several times what was required but actually doing it is less easy than it sounds. It would appear that this one also needs more than 2 hands i.e. a helpful second human which I don't have. In the end, after much "effing and blinding" this went together again with instructions to self:
"Don't do that again!"
Unfortunately, I don't often listen to myself and the worry bead thing happened again. I now have it in pieces next to me again and fully expect it to stay this way for a while. I am definitely not terribly bright - but the lovely shiny toys keep talking to me!

Thank you to both of my wonderful puzzling friends who have delighted and frustrated me for so long.

Anyone Want a Pelikan for Christmas?

Upcoming delights from Jakub and Jaroslav
10 or 11 days ago I received a rather large box! Mrs S was very unhappy about the rather large box and I had to apologise profusely about the state of my collection and how it had spilled everywhere in the house. She did have to admit that my recent partial tidy up had improved things but foresaw (probably realistically) that the latest set of arrivals might just undo all that. But...I have readers to think of and the danger I take on with every delivery is just for you!

Bornage

Bornage by Stephane Chomine
I adore Stéphane Chomine’s designs - they always have a simplicity to them yet also are a real challenge. This is definitely the case here with a level of 17.6.4.5. How can it be so difficult? There are just 4 burr sticks (gorgeous Purpleheart) in a very simple frame (made from Merbau). Starting off, there are only a few moves possible and they stop in a blind end very quickly. Only one sequence seems to progress and this promisingly opens up the visibility inside very quickly. After a short while it really looks like progress has been made and it would separate soon but I came to a hard stop here. Despite great visibility, I could not progress and was locked going back and forth to this position again and again. I must have been missing something but could not see it for the life of me. Eventually after putting it down for an hour I came back to it and then was able to find the sneaky move and dismantled it. 

 

As always with Stéphane it is a stunning design, beautifully made with moves as smooth as silk that was a delight to solve.

Vega

Vega by Stewart Coffin - 2 versions available
Vega is another classic Stewart Coffin puzzle based on the triangular star base puzzle. They are absolutely gorgeous in a Zebrano with either Purpleheart or Wenge corner tips. As you all know these puzzles dismantle into 2 groups of 3 pieces before fully falling apart. The 6 pieces here are identical and I thought that this would mean that there was only one solution. Interestingly this one only comes apart in one specific direction which took me a good few minutes to find. The craftsmanship is absolutely perfect with no clues whatsoever as to which direction it dismantles. Eventually I found the direction of travel and had it apart to admire the precision of the angles. 

Classic triangular star pieces
Then I reassembled the trios of pieces to put together in 2 halves and they were blocked! This surprised me - the puzzle has handedness and can be assembled in either way but the pairs must be correctly grouped. I corrected the assembly and after a little while fiddling to get the alignment just right (it needs to be absolutely perfect to get them to slide on each other) I reassembled the beautiful star. Later, I disassembled again and thought about my initial difficulty and realised that there are 2 distinct assemblies of these pieces which have a set “handedness” - the end result is identical but they are different assemblies. As a mark of the precision, they fit together absolutely perfectly regardless of how you pair up the pieces or which handedness you choose to assemble them in. All decent puzzle collections should have an assortment of these star based designs.

Rosebud

Rosebud by Stewart Coffin
I have never actually seen one of the Rosebud puzzles in the flesh/wood before! I have seen photos and blog posts but people seldom bring them out to let others play with them because it's such a difficult challenge to reassemble it. This amazing design by Stewart Coffin is one that sets the masters of their craft apart from a mere journeyman woodworker. Rosebud is a coordinate motion puzzle that is one of the most challenging to manufacture as the tolerances have to be accurate to fractions of a millimetre to allow the pieces to slide on each other and for it to close up into the rosebud form without showing any gaps. I have never owned one of these because the level of craftsmanship makes them very rare and very expensive. Of course, Jakub and Jaroslav have managed to make a superb version that is absolutely perfect with the wood choices being evocative of a rose and the precision being simply spot on. Finding the proper pressure points to cause it to slide apart is difficult but then you need to control it so that it doesn’t fly apart. You need to catch it in the expanding splendour that reveals the Rosebud come into bloom before the petals fall off and it dies like a fading flower. 


Just like the Vega, this puzzle is another based on the triangular star base but is fully coordinate motion. As are many puzzles based on the star, there is an alternative assembly which is a fun challenge even if the result is not interesting. You need to work out the proper combination and orientation to allow the pair of triplets to interlock. Having found the incorrect assembly and taken my photo, I couldn’t for the life of me remember the orientation that it went together and spent a frustrating time trying to find the disassembly. 

I definitely recommend buying the jig!
Reassembly into the true Rosebud form is the real challenge. It is so difficult to assemble that most puzzlers need a jig (or 4 more hands) to hold the pieces properly for the assembly. Luckily Pelikan have made a jig to help you which you may choose to buy with your puzzle. I heartily suggest that you do and I hope that you use it correctly unlike me! I didn’t realise that it has one side for display of the blooming rose and the other for reassembly. I spent a good hour or more desperately trying to assemble the puzzle using the jig the wrong way around. Even using it the correct way, the reassembly is a massive challenge. This puzzle is a masterpiece and should be on every serious collector's shelf.

Dracula

Dracula by Alfons Eyckmans - NOT just another 6 piece burr
Alfons Eyckmans is a master at designing burrs (in fact all interlocking puzzles). The Dracula is a member of his Burr zoo set of puzzles but unlike previous designs this contains a blood drinking vampire in his coffin. Fittingly, he is made from a very pale Maple inside the light excluding Wenge six piece burr. This is one of the most enjoyable burrs I have played with for a long time. The design is very reminiscent of the fabulous 6 piece burrs designed by Stephan Baumegger which have the sticks based on a 3x3x9 grid which allows very complex interlocking shapes to be created. They must be an absolute nightmare to manufacture but, as expected, they are absolutely perfect. The disassembly did not take me very long but was absolutely delightful and even Mrs S laughed to see the contents hidden behind the spoiler button.



Pearl

Pearl by Lucie Pauwels
This attractive puzzle by Lucie Pauwels is sent out in a special travel conformation - it is a nice hollow 3x3x3 cube containing a nice marble (pearl) and held in a frame by long dowels that go through each corner along each axis. The dowels need to be pushed out and the cube dismantled. I scrambled the pieces and left them for a while to lose any memory of the positioning and then set to rearranging the pieces back into shape. This is a nice logic puzzle that shouldn’t take long for experienced puzzlers but might be a decent challenge for a beginner. I found it quite fun after the effort required for the others. Looking at a Burrtools file there are 2 possible assemblies but I have so far only managed to find one of them.

Twinkle star

Twinkle star comes in a beautiful box
Inside a lovely puzzle
There are two puzzles by Osanori Yamamoto in this selection and they have been beautifully made in miniature form with extreme precision and are sent out in a lovely little box made from Cherry which also has been beautifully made. The box could definitely be used elsewhere like a bedside table for jewellery or another small object. Inside the box is one of Osanori-san’s delightful puzzles with captive pieces on a board. The aim is to rearrange everything so that the Merbau pieces can be removed from the Wenge frame and then reassemble later. This one requires a couple of nice rotational coordinate motion moves before they can be removed (there is also an alternative route of disassembly that requires some linear moves as well). This was not as difficult as some of his other challenges but fun all the same.


P-Badge

P-Badge comes in a lovely little box
Beautiful puzzle inside
The second of Osanori Yamamoto's lovely little sliding piece puzzles in beautifully made boxes is P-badge. This one has 3 P-shaped pieces made from Wenge held on an Acacia frame. The gorgeously precise puzzle is perfectly encased in an Ash box. The removal of the pieces requires only linear moves and is delightful in the sheer perfect precision of the manufacture. The real challenge is the reassembly after scrambling the pieces and leaving them for a while. It’s not a hugely difficult challenge but a nice one to show off to beginners.


Eros

Eros by the incredible Dr Volker Latussek
Did you enjoy Casino by the amazing Dr Volker Latussek? If not, then there’s something wrong with you - in my opinion it is one of the best puzzles of all time. If you did like Casino then you will love Eros! Volker has altered the Casino design he has split 2 of the circles in half and added them to adjacent edges of a square to make a couple of hearts. These 2 hearts (made from a lovely red Bubinga) need to be placed in the beautifully crafted box with the rest of the disks which have been made into rounded squares to make the challenge tougher. Initially, it’s even pretty difficulty to work out an arrangement that could possibly fit in the box...the dimensions will not allow a stack of 4 pieces (they all have the same thickness). Then, once you think you have worked out an assembly, the actual insertion of the last 2 pieces is incredibly hard to work out. The lip on either side of the entry hole really gets in the way. There is no squeezing it through...it just won’t work that way. The correct sequence of moves is essential. I absolutely adored this puzzle, I personally think it is slightly simpler than Casino but the Aha! moment is just as delicious. I think this is the pick of this release from Pelikan.

Snooky

Snooky by Stephan Baumegger
Stephan Baumegger designs some very interesting puzzles and my favourite burrs from him have been his 6 piece burr variants with complex piece shapes that turn the puzzle into a sort of burr with a maze. The Snooky is just one such burr...it is just 6 pieces but the basic sticks (Pink Oak) have been modified by the addiction of small Wenge extensions. These extensions make it look very attractive but block many moves that you might want to try. The difficulty level is not particularly high at 10.1.2.2 (which to me is a good thing) and the number of blind ends is just right. There are quite a few moves to start with, but once the beginning of the correct pathway is found then the disassembly is a matter of exploration. I really enjoyed it and had done enough back and forth that I was also able to reassemble it without Burrtools.

Snooky pieces
All in all, a lovely addition to any burr collector’s display.

Corner pack

Corner Pack by Lucie Pauwels
Corner pack by Lucie Pauwels looks absolutely stunning with a pair of very striking woods - the box is made from Acacia and the rather complex pieces to be placed inside the box are a nice grained Wenge. It arrives with all the pieces inside but flush with the top surface. There are 3 L-shapes of various sizes and 7 corner pieces as you can see in the photo. All the pieces need to be placed inside the box to end up with the pieces under the lip which is on 3 of the 4 sides. This means there are a lot of complex shapes to be placed and a restricted entry as well. Once packed, the entrance to the box will be completely filled.

This is an incredibly difficult challenge which I have failed to solve after 3 days of attempts. There is certainly a logic to this because the pieces are quite complex and the correct way to make them link together is rather awkward and then trying to get that to happen through the top hole has proved completely impossible for me so far - I will keep at it! This is an essential for you packing puzzle aficionados.

Detonator

Detonator by James Fortune
James Fortune has appeared in the puzzle world in the last couple of years and this is the first puzzle of his that I have tried. He designs fairly complex burr type puzzles (and also SD puzzles) which he 3D prints and sells from his web store. I have not bought any as yet but should probably remedy that soon. As always, I think that most puzzles look much nicer in wood and the gorgeous detonator made by Jakub and Jaroslav here is made from a vibrant Padauk, Wenge and Garapa. It looks just like one of the detonator boxes you would see in the old cartoons. It is not for the faint hearted as it has a solution level of 56.7.3.1.2.2.2.2. The version here has quite a lot of moves which lead to several possible pathways. So far I have not managed to get very far due to my need to keep moving back and forth so as not to get lost. The movements are beautifully smooth and the bevelled pieces don't catch on each other preventing discovery. This is going to be a difficult puzzle to solve but should be a lot of fun. It will look glorious on display as well.


So what should you buy? Well, I would suggest all of them! But if you cannot manage that extravagance then pick those that meet your own puzzle preferences. BUT Everyone should get Eros! Everyone should get the Rosebud (don't forget the jig) and my next favourite amongst them has to be the Dracula.
