A Well-earned Special Winner

Elbow Room by Goh Pit Khiam
Goh Pit Khiam has figured quite a bit on this site over the years. He's very prolific but not just someone who exhaustively creates Burrtools assembly puzzles. He has a very odd brain that finds things that are clever and interesting. This week's puzzle is something very special.

Elbow room was a huge hit in the IPP design competition. In fact, it was considered so so good that it won a special award - something I have never seen before. The Jury gave it their Grand Prize and the Puzzlers voted it as their favourite from all the puzzles in the design competition. Together, this meant that it was awarded the "Puzzle of the Year" award - this is something I have never seen before and it is absolutely well deserved. It was my number one puzzle which I voted for and that is quite something because the field was so strong. I have already seen that several people liked it so much that they have created their own 3D printed versions. I really wanted to get it in wood - that way I would have a fantastic puzzle to torture people with and a wonderful wood object to go on display.

I had my suspicions about who had made it but wasn't certain until the day of the announcement of the winners. and literally as soon as it was confirmed as the winner and the craftsman revealed, I sent an email to Tom Lensch from the IPP dinner. It was so good that I couldn't even wait until after the dinner had finished! Tom responded pretty quickly and put me on the list for when he had made them. I must have reached the front of a long queue last week as I got an email asking to confirm my address and requesting a little PayPal transfer. The hop over the pond seemed to be exceptionally fast this time and just a few days later Mrs S was frowning at me for yet another delivery. She really shouldn't complain - I have slowed down my buying considerably this year!

The puzzle was nicely packed and I quickly revealed a nice chunky box made from Cherry with a single Voxel hole in the corner and Tom's mark on the inside. The blocks are a beautifully grained Sapele. There are 2 pieces with an extension on one side and a slot to take the extension and 2 pieces with just slots only. Finally there is a single square cotton-reel type piece which can join two slots. The aim, clearly is to place all the 4 pieces together inside the box as a 2x2x2 cube. However this is only possible if it is done as a sliding pre-linked snake assembly that transforms into a cube during the insertion.

Make an assembly to slide in - NOT like this!
Just the very idea of doing that is something that kept me going in the competition area. There is something very tactile about these pieces and making different shaped snakes of linked pieces that keep failing to be able to be inserted through the orifice was quite compulsive.

I think I must have spent a good 30-45 minutes being laughed at by various puzzlers when I kept failing but they also encouraged me to keep going.

Initially, I was just creating random assemblies and failing but after a while, I actually had to start think©ing about what I was trying and the logic gradually dawned on me. Finally I had my assembly and received a small cheer from puzzlers nearby. The IPP is great (just like the MPP) for having fun poked at you, receiving support when needed as well as cheers when earned. It felt great and due to the elegance of it, I had to keep it as my number one. My number two was the Step by Step by Yavuz Demirrhan because it was also a clever packing puzzle with an unusual twist to it. Elbow room won out for me because of its sheer elegance.

When I received my own copy, I had to play straight away and it was just as difficult several months later despite having been solved by me in the past. I spent a little while trying random things before my logical thoughts from June came back and I proceeded to work on it systematically. It didn't take quite as long this second time but was just as enjoyable.

This was sooooo good!
If you get a chance to work on this then jump at it - it is literally one of the best puzzles of the year. It is so simple in idea and yet so tough and logical to solve. The wood version is certainly the best but even a 3D printed one should be fun.

Thank you Tom.


It's arrived! Hooray.

Safe 2 from Pelikan design
Jakub and team had not managed to get the Safe 2 SD puzzle ready in time for the last release. Mine arrived on Thursday and so far I have found my first tool and managed to use it make things happen inside. I have no idea what it has done but there's some significant movement going on. I can also undo what I move but then gotten no further. 

It is still not yet up for sale but preorders are open if you contact Jakub. 

From my previous posts, the Frau L. and one version of Loach Bed is sold out but the rest are still available as I type so you should have a look before they sell out.

Back to Basics

And Still Not Good At It!

Eleventh Hour by Goh Pit Khiam
Once or twice a year, Tom Lensch emails out what he has been working on and lets interested puzzlers place orders. A few weeks ago the email came in just as I had purchased a few others and so my PayPal was tight and I also was aware that if post brought me too much then Mrs S would Whack! Ouch! me into oblivion.......again! I resisted the urge to buy it all and just picked a couple that I figured might just be possible for a man with my meagre bwain and which would not break the bank or Mrs S' patience. A week or so later I received the Eleventh Hour by Goh Pit Khiam (out of interest, I have seen the name as Goh Pit Khiam and Pit Khiam Goh - can anyone tell me how it should be written?).

It arrived in pieces made from what looks like Maple or Cherry and has Tom's fine stamp on one of the pieces. 4 pieces to construct into a 4x4x4 cube - surely, I must be able to manage this without too much difficulty after all these years? I set to work last weekend and very quickly managed to see the final position of all the pieces - yes, this might be an easy one! I was able to assemble any 3 of them quite quickly into their correct places but always was unable to get the 4th piece in. The way the pieces were interlocked always ensured that one was completely blocked from getting past. This was nice and fun - just the challenge I had been hoping for after desperately trying to solve the 3rd in the Hoffman suite from Pelikan. Whilst I have your attention, there are still a few left of the Sukiyaki, Steamboat and Fabrick puzzles on the Pelikan store - well worth a look.

I have had a lot of work to catch up on after my holiday and must  insist on using this as an excuse for my feeble bwain failing on this puzzle for several days. I was only able to play in the evenings but was getting nowhere fast. I even emailed Tom to ask whether this was a TIC but was reassured that it is "just" a simple interlocking puzzle. Damn! I'm rubbish at puzzles! Finally on Friday evening, I assembled my cube with a sigh of relief and a memory of the early days of my puzzling "career" - this simple interlocking cube takes me back to the fabulous creations from Rich Gain's Microcubology. Over that first couple of years of PuzzleMad, I must have bought 15-20 gorgeous interlocking creations (they sit in a tray on display in my second puzzle room - Whack! Ouch!). Only toward the end did I buy them in the disassembled state and solve them that way. I had kind of hoped that I might be better at them but Tom has proved me wrong!

5 days to assemble - that's rubbish!
Goh Pit Khiam also designs some interesting packing puzzles which I usually fail to manage but the Confound Space looked solvable by a mere human and I couldn't resist:

Confound space
6 blocks to place in a box with a limited opening - this is usually impossible for me.

Interestingly, I made a couple of discoveries very quickly and my "what if" sense made me try a few things and I was rewarded with my Aha! moment after just 20 minutes! Phew! I am not a complete eejit!

Pelikan's Post IPP Release

Wow! Just Wow!

Soon to be released by Jakub and team!
I seem to have received a delivery at the beginning of last week and the race was on. I had 7 fabulous creations to work on in just under 2 weeks. The upcoming puzzles from Pelikan are expected to be released later this week - probably 31/7.

From Back left we have:
Cabrio by Dr Volker Latussek
Cubi 8 Plus Alpha by Frederic Boucher
Camel by Theo Geerinck
Hitch by Émil Áskerli
Minima Tower by Frederic Boucher
Unlawful Assembly by Pit Khiam Goh
Curly Burr N8 by Frans de Vreugt

This is an amazing set of puzzle designs and beautifully created by the Pelikan team - there will definitely be something for everyone here.

Unlawful Assembly

Unlawful assembly by Pit Khiam Goh
I started with this delightful puzzle by the master of sliding move puzzles. I already own this one made from acrylic but the wooden one looks much more lovely. Pelikan have constructed this one from Garapa, Bubinga and Oak with wonderfully contrasting colours and a stunningly finished tray to pack the pieces into. There are 4 identical stepped pieces and a cross to fit inside the tray with the challenge being made by the fact that there is a considerable lip covering the tray making insertion of more than 3 pieces quite challenging. It is fairly easy to work out several possible square(ish) assemblies that might fit when playing outside the tray but getting them into the tray quickly gets quite confusing. The temptation is to try and squeeze one of the pieces diagonally under the lip of the tray but don't bother - that requires force and is the wrong way to do it.

The first time I worked on it, the solution took me a good hour or so to solve and that was only because I was familiar with the type of challenge. I gave this to a couple of my assistants/ODPs at work and watched them spend a couple of hours failing to solve it. Eventually I came back to the pieces all packed inside and I happily told them they had cheated! The pieces were in the conformation that can only be done by force. At this point they couldn't remove the pieces and a joint broke forcing it out. This is a great puzzle for beginners but don't let them attempt it unsupervised.

This puzzle should be in everyone's collection!

Curly Burr N8

Curly Burr N8 by Frans de Vreugt
This has been beautifully made with Maple and Merbau. Frans is an interesting designer - he is not prolific but everything he designs has something very different from the usual run of the mill burr designs. There are either interesting shapes or, more usually, interesting ways that the pieces interact and move. The Curly Burr N8 is definitely designed along those lines...it looks like a standard 6 piece and, indeed, there are 6 pieces, but they form frames that interlock inside each other along the same axis as well as interlocking along perpendicular axis. The upshot of this is that the pieces need to move apart from each other before any axial movements can occur. This makes it much more fun and much more mind-bending to solve. There are a few blind ends but not along long pathways and then the first piece comes apart after just 8 very odd moves. After this the remainder dismantles sequentially. The moves are so unusual that despite paying proper attention to what I had done, I could not reassemble it without Burrtools.

6 pieces that look like standard burr sticks
I think that even the burr aficionados amongst you will find the reassembly from scratch a real challenge  due to the unusual way the burr pieces move.

Camel

Front side
Back side
Yes!!!! I adore the animal themed puzzles that Jakub and Jaroslav produce. I know they are often very difficult to design and manufacture but they are just so lovely and give me an excuse to keep another one on display in my living room. Mrs S was away when this batch came in and when I showed her the photo of the delivery even she admitted the camel was very cute and really realistic. It has been crafted from American Cherry which gives it a rich brown "camel" colour. This is a collaboration with a master designer and craftsman, Theo Geerinck which means that the solution will be interesting as well as good looking.  

When first playing with it, only 3 pieces move and I comically pushed and pulled them and then tried to rip the legs or head off it. Of course, that doesn't work. I don't think any self-respecting camel will let you tear a leg or head off without complaining vigorously at you. I was stumped at this point for a rather long time. The fun thing with these sorts of layered constructions is that you cannot tell by looking at them which parts are supposed to be mobile and which are glued together. This leaves you pushing and pulling pretty much everything that you can get a grip on. After a whole day of getting nowhere, I tried a new technique and there was a "click". Aha! Then another click and another before I was able to remove a piece of camel anatomy. Before long I had the poor animal in pieces on my table and was able to see the ingenious locking mechanism which included a couple of pieces that are hidden inside. I scrambled the pieces and left it for a couple of hours and attempted the reassembly. Whilst not impossibly difficult, even that was a fun challenge as I had lost my orientation of several pieces.

This is wonderful and perfect to display as part of a puzzle menagerie.

Hitch

Hitch by Émil Áskerli
Émil is another very interesting designer producing burrs and interlocking puzzles with pieces that have clever ways of interacting. His Puzzlewillbeplayed page is absolutely fascinating. I initially thought that Hitch puzzle (made from Purpleheart and Zebrano) was a straightforward burr but I have ended up reclassifying it in my database as an "Interlocking puzzle". It looks like an 8 piece burr and is indeed made from 8 sticks but the interaction is interesting and requires a series of moves that lead logically one into the next until it is disassembled. Does this sound too easy? Fear not, the moves are very nicely hidden. Initially there are a few pieces that can move and the whole puzzle can form several different shapes at first. I went round and round in circles from shape to shape and looking to see whether it freed anything up. It requires careful inspection of all the pieces that you have in each conformation until you suddenly notice that a new move might be possible. Pelikan have constructed this nice and tight so that nothing moves without a deliberate attempt meaning you need to actually work out what to try rather than random pushing and pulling of the pieces.

Not really classical burr sticks
Only 7 moves are required to remove the first piece and 13 for complete disassembly but the discovery aspect is joyous. Even more fun (and definitely possible because I did it) is to reassemble it from scratch with scrambled pieces. A few of you may be able to do it without memory of the disassembly, but most experienced puzzlers should be able to work out the assembly with a little work. It's brilliant!

Cabrio

Cabrio by Volker Latussek
Doesn't look like much but it is absolutely brilliant!
No Pelikan release is complete without a design from Dr Latussek! When opening the package, it looks very understated. All you can see is a very nicely crafted box made from American Walnut which Pelikan have failed to close properly. Pulling off the lid reveals some rather lovely Zebrano pieces inside forming an apparent 3x3x3 cube. No wonder the lid couldn't close properly - it needs to be slid on from the side and the pieces are in the way.

Looks like a cube
5 pieces to be packed

The upshot of the sliding mechanism of the lid is that this is effectively a 7 piece puzzle with the pieces needing to interact with the base and the lid to get the cube inserted inside and the puzzle closed. It is very reminiscent of the fantastic Slide Packing puzzle by Hajime Katsumoto that won the Puzzlers award in 2016. This time instead of just 4 pieces to insert, there are 5 and 3 of them are non-planar shapes which makes the solution really quite counterintuitive.


I found quite a few 3x3x3 cube shapes that were possible but of course they all blocked the assembly of the lid and needed to start with a completely fresh way of thinking about this. Like many of Volker's puzzles, you need to think about the last piece to be inserted and how you might get access to that and then try and work with the remaining pieces and the lid to make that final assembly possible. There are 2 obvious possibilities for the final piece but then you will realise that you also need a proper plan for the penultimate piece and it is not as straightforward as you might anticipate. I worked on this for several days before I had a glorious Aha! moment and managed to put the lid on properly. This is a work of genius, just like the predecessor.

Are the pieces inside? Take my word for it - after a several day struggle, they are!

Cubi 8 Plus Alpha

Cubi 8 Plus Alpha by Frederic Boucher
This startlingly gorgeous creation by Frederic Boucher is one of the picks of the bunch this release. Not only is it stunning, it is also a very very challenging fun design. Frederic has an amazing and rather warped mind. He has collaborated with several of the very best craftsmen in the world to get his designs to the masses as well as makes some limited runs of his puzzles himself. I am delighted that he was able to find someone willing to make such a complex puzzle available. This beautiful creation has been produced by Pelikan from Wenge, Pink Oak, Purpleheart and acrylic. 

Some very interesting shapes here
There are 8 cubes with sticks of 2 different lengths which, when assembled together, form a 2x2 cube.  I have to admit that just making the cube (albeit with some holes) is a massive undertaking and really quite fun - its a sort of 3D jigsaw that has to slide together in order. However, the real challenge is to pack that cube inside the box so that no holes are visible from outside (unique solution). through a 1 cubie sized hole in the box. Frederic wrote that the pieces interract together like a train on its tracks during solving.

This puzzle is amazing and very very difficult! I might have needed some help with this one! 😱

Minima Tower

Minima Tower by Frederic Boucher
Allard has shown off a whole series of the amazing Minima puzzles created by Frederic and there are a good few more to come. Eric Fuller even converted one into a sequential discovery puzzle. Here we have one of the designs beautifully made by Pelikan from Mahogany and Ash. It doesn't look like much with a 2x2x4 box (upright it will be a tower, hence the name) and 4 simple L-shaped triominoes to be placed inside so that the 5 square holes are each covered by a piece of Ash. There is a single 1x2 voxel entryway. The box has lots and lots of finger holes for you to manipulate the pieces as there will be rotations required. I have only been working on this one for a day and so far not got even close to a solution. These puzzles are a delight and a real challenge but still very approachable by both beginners and advanced puzzlers alike. This will also be an essential purchase for many of you.


This is an absolutely amazing batch of puzzles to be released this time. There is definitely something that you will enjoy. My favourites are the Camel, the Cabrio and Minima Tower.

Here We Go Again - Spring With Pelikan (part 1)

Pelikan offering for April
Hello again everyone! I'm a bit behind with my puzzling this week - it's been a bit hectic and I have had to do extra work to cover sickness and other "stuff" at work. I was hoping to have all the reviews for the latest offering from Jakub, Jaroslav and team all done in a week but I will have to split it up into two posts. We have some terrific challenges on offer here:

From the back left:
Euclid for Bernhard by Dr Volker Latussek
Stefka-flop from Dr Volker Latussek
SISU by Benjamin Heidt
YLEM by Benjamin Heidt
Airlock by Pit Khiam Goh
Xmas Stocking by Osanori Yamamoto

These should be going on sale on April 15th hopefully. I can review four of them today and plan to have the rest of the reviews up next weekend. Here we go...

Airlock

Airlock by Pit Khiam Goh
Pit is an incredible designer - I have seen his puzzles do very well in the design competitions and I have a good few of his designs in my collection which have appeared in this blog. This one is wonderful as well because of a series of really nice Aha! moments.

I had been certain that I had seen this somewhere before but a search of the internet only found a few pictures that did not ring any bells. It is a tray packing puzzle with a restricted entry hole. It has been beautifully made by the Pelikan team from Wenge, Purpleheart, Mahogany, Maple and Limba with an acrylic grille over the top. The delivery placement is useful to keep the pieces together and shows that certain moves will be required. removing the pieces reveals that all the pieces will need rotation and that 2 of the pieces are really quite restricted in how they move and can be placed.

The aim is to place them all back in the tray without any of them appearing in the entry hole and this is a real challenge. I started with this because it looks so enticing and I was hoping would not be too horrendously difficult. My solving success the last couple of weeks has not been great and I wanted something to boost my confidence. Erm... whilst I did solve it, it was not a quick easy solve. The pieces can conveniently be placed on top of the grille for planning purposes and it quickly becomes apparent that almost everything you try ends up blocked. Planning to get the most awkward pieces out of the way was an interesting challenge and taught me a lot. Random placement will not work for you here. You will need to think© and plan ahead. There are several of these Aha! moments and the solution is delightful. This is a fabulous puzzle that will delight experienced puzzlers as well as newbies alike. I will be taking this to work to torture colleagues and medical students during the day.

Xmas Stocking

Xmas Stocking by Osanori Yamamoto

An odd time of the year to have this one brought out but delightful nonetheless. I would suggest that you all buy this as either a belated Christmas present to yourselves or as an advance one for December for the significant other puzzler in your life. Hopefully you can stash it away for long enough and still remember where you put it. It is a rather pocketable size - perfect for your own Xmas stocking. As delivered there are 3 little feet inside the stocking already and 2 outside. Time to work out how to get them all inside.

Like many of Osanori-san's creations, there will need to be rotational moves but the box has very tight tolerances and the pieces can only rotate in certain ways (even with the box empty). Add in a few of the feet then the restriction gets significantly worse. As usual, I would suggest that you work this one in reverse - find out how they can be packed and then see if that packing is removable. This approach gives a couple of great Aha! moments again to help you on your way but even then, more thinking© is required. Gravity may be helpful to you at times and less helpful at other times - there is very little room inside for poking a finger in. Planning is everything with this one!

YLEM 

YLEM by Benjamin Heidt
This is the second time the Benjamin has appeared here and the second Pelikan release that includes his designs. There is something very clever about his designs which are delightful to see on display and also brilliant to explore and solve. This stunnning creation in Acacia and Purpleheart appeared to me initially to be "just" an 18 piece burr but with an odd configuration of the pieces leaving a hole in each of the 6 faces. But...this is not "just" another 18 piece burr - it can quickly be seen that it is a 19 piece burr (something I have never seen before) and it requires a fair bit of exploration to work through. 

These high piece number puzzles always frighten me because they often either have an incredibly complex/high level disassembly or after a couple of pieces are removed, can become very unstable and collapse on you. I can reassure you that this wonderful burr has a fantastic and almost logical unlocking mechanism which is an absolute delight to work through. There are a few moves available at first and the easy ones don't appear to lead anywhere. After some exploration and a nice Aha! moment, a new move becomes available which is very helpful in revealing the beginning of a locking sequence. The disassembly is a wonderful and very achievable level 19.2.2.3.2.3.2.2.1.1.2.1.1.1.1.1.2. giving a total of 46 moves to take it completely apart.

19 pieces - beautifully made by Pelikan!
This monster was beautifully stable right down to the last few pieces. I very much doubt that many people can assemble this from scratch but a few of you will be able to. Some may be able to remember what you did and be able to backtrack. I, on the other hand, barely remember my own name and therefore had to resort to Burrtools for the reassembly. Entering the pieces into that wonderful program and then adding the colour restrictions for the assembly was also great fun and a nice part of the challenge. The assembly required quite a bit of dexterity initially but was a delightful part of the challenge. If you like complex burrs but are frightened of too high a level then this is perfect.

I hope to finish the rest of the puzzles this week and get my reviews up for you next weekend.

Keep an eye out for these - they are fabulous for all levels of puzzler.

A Gift That Was Fun and Gifts That Are Humbling

Boxed Six Board Burr by Frans de Vreugt
The Dutch tend to be pretty amazing puzzlers! I know several and work with quite a few to produce the CFF journal and they never cease to amaze me with their skill, knowledge and sheer bloody-minded persistence at solving things. I hope, one day, to be as good a puzzler as the Dutchmen (and woman) that I have met. I doubt very much that I will manage it but I'll keep on trying!

At the last MPP, Frank was thinning out some of his puzzle collection (only the ones that aren't part of his particular special interest, Kumike and Journet puzzles) and he handed me a couple of IPP exchange puzzles. Both of them had been given by Frans de Vreugt. The Boxed six board burr was one of Frans' own designs which had been made in association with Buttonius and given away in 2004 at the Tokyo IPP (24). I did not realise properly what it was because it had been packaged with 4 of the burr plates in the frame. After I took that assembly apart and realised that the pieces are really quite simple, I was very attracted to it. I am awful at assembly form scratch and board burrs are particularly difficult for me. I have had the RIPley board burr next to me on my desk for the last 3 years and have not even come close to assembling it!

RIPley by Andrew Crowell and made by Brian Menold
I just cannot solve it despite years of attempts!
So with some trepidation, I began fiddling with the boxed burr earlier this week - I figured that with such simple pieces, I might actually stand a chance. It is very portable being only 35mm across and easily pocketable for fiddling at work. Unfortunately, I seem to specialise in very  major surgery these days and I have to keep my concentration 100% on what is going on - I kept taking the puzzle out to play and quickly realised that I couldn't do it at work. In the evenings, I had better luck and managed to find a nice logical assembly of the board burr outside of the box and attempted to repeat the assembly with the box. Oh dear, the slots in the faces of the box are very restrictive and my "beautiful" assembly wouldn't work. At this point I seemed to have some blinkers on and I couldn't find an alternative assembly for a couple of hours over 3 evenings whilst watching TV with Mrs S. Eventually I found an assembly that looked like it might just work - after carefully arranging the pieces in the right order I set to work and assembled the puzzle:

Assembled - very simple and very clever
I kept it assembled for a few days until I had time to take my photo and then discovered that I couldn't take it apart. It's quite humid and hot in the UK at the moment and some puzzles are getting a little tight. This was a little tight but the internal edges were not bevelled and moves had to be perfectly aligned to get them to move. I had found one move but the second move would not happen. It took me a rather frantic hour to find that a different piece needed to move first and then it could be disassembled. Just a little gift from a friend - it was great fun and a lovely challenge.

Quantum Entanglement designed by Pit Khiam Goh
Another present from Frank at the MPP was the boxed 6 piece burr very reminiscent of the Internal combustion burr made from metal that I reviewed way back in 2011 except this has 6 sticks that lay across each other in 2 groups of three. When I took the photo, I thought that the aim was to find a way to insert the two loose burr sticks into the puzzle as it had been given out. I did have a quick fiddle and it looked to me like the pieces that were in the box were actually captive. Doh! I am not terribly bright, though. After my success with the boxed burr, I properly looked at this and realised that it would be impossible to insert the other two pieces in this configuration. I then spent 10 minutes and removed all the pieces (eejit that I am I forgot to take another pic!). I then looked into how these pieces could be positioned that might form an assembly. I did find a few and realised that I was in trouble. If I could easily find a few ways to orient the pieces that might work then there were probably going to be quite a lot and I would never be able to work out which was the right one let alone find a 48 move assembly.

I was not particularly upset by this as some puzzles just need Burrtools and I find that whole process really quite fun (I know that George Miller considers it perfectly acceptable to play with BT as a solution method). I programmed in the pieces and it spat out a solution in about 3 or 4 minutes. I had been correct to give in so fast - there are 964 assemblies and only one solution! I assembled the puzzle using BT and was amazed at the beautiful interplay of the pieces - the box literally is only there to keep them all in the correct planes. I have kept it assembled and will work on a disassembly at a later date but I fully expect this to be a rumblingly impossible experience for me!

The WDIGMI Xmas puzzle from Tanner Reyes (made by Tye Stahey)
I had admired the Xmas question mark puzzle on Facebook a while ago but had not bought a copy because I figured that it would be too difficult for me. Tanner saw my admiring comment and had a copy left over and he generously decided to send me a copy as a gift. 

Tanner burst onto the puzzling scene with his incredible YouTube channel "What Did I Get Myself Into". In it he shows off some of the most complex and beautiful puzzles that have ever been produced and does it with humility and humour showing off his huge enjoyment in this crazy pastime we have gotten trapped doing. His collection is pretty awe-inspiring and having started puzzle design and teamed up with Tye from Nothing yet designs. The puzzle had obviously been made for Tanner to give away as Christmas presents and mine arrived complete with a lovely wooden Christmas label. I put it down for the week whilst I played with the supposedly simpler puzzles above and have been working on it yesterday evening and today.

There are 7 pieces to fit inside the question mark and three holes in the top to place them through. Except the bottom hole is too small to insert any pieces through and must be there to allow manipulation and orientation as the pieces slide down. This puzzle is lovely to play with and very tactile. So far I have gone through the gamut of randomly inserting pieces and moving them into random positions, randomly inserting pieces and moving them into specific positions and finally trying to assemble a reasonable shape outside the puzzle frame in the hope that I will find at least something that might possibly fit. I doubt very much that I will mange this but it is gorgeous to look at and beautifully made. I do not know whether it can be solved using Burrtools - I suspect that the holes in the top mean that rotations will be needed but if I ignore those then I might at least find an assembly or two. First of all, I will need to work out how to use the non-rectilinear grid in BT. Again, humbled by the generosity and brains of my fellow puzzlers. I wish I was as good at solving these things as people think I am.



I was delighted to receive the Burrtools file for the Sher-lock - a notched Trifecta direct from Girish himself. I had tried to find an assembly for the puzzle with the key pointing frontward but despited finding several possibilities, there was no way that I would be able to put it together. My plan is to assemble it using BT by my side and then leave it for a while before attempting the disassembly myself without having any memory. As expected with all of Eric's creations it is gorgeous in this orientation:

Time to work on taking this apart.

Also - for those of you who have purchased the "Ode to the Bevel" puzzle by Dr Latussek from Pelikan, a correspondent of mine who is exceptionally talented has found a second solution to the puzzle. It is very clever even if not quite as elegant. If you have solved it one way then you should look for the other  solution. I love it when this happens as it gives you much more bang for your buck. I do hope that another run of these will be made - it is a terrific puzzle.

Counting to 4 in the Correct Order

Number Blocks
Mrs S has been away for over a week visiting the Outlaws. She returned home yesterday whilst I was at work and this meant a  flurry of cleaning up my mess (with dozens of puzzles lying all over the house) and then making the place look vaguely presentable and doing a bit of my assigned DIY over the last few days. This has left me knackered but at least I have managed to solve a few puzzles to blog about. Today I have a lovely puzzle that was great fun and is absolutely perfect to take to work for "normal people" to play with. It's a little bit of a shock to have to finally admit after all these years that I am "not normal"! 😱😱

Recently, I had a little chat with Tom Lensch via email when I was seeking a copy of his award winning 4 Pac puzzle designed by Hajime Katsumoto. This had been very highly rated by Allard as well as appearing a few times in the EPP book. Of course, Tom always has a bunch of creations on the go at any one time and sometimes has a few toys lying around from previous batches. He talked me into purchasing a new version of the Melting Block puzzle (it has a bunch of gloriously coloured woods which I couldn't resist) as well as the Number blocks by Goh Pit Khiam.

4 Pac
I immediately fiddled with the 4 Pac and realised that this was going to take some serious working out time which I didn't have straight away and suspected that the New Melting Block might be totally beyond me, so I started on the Number blocks. 

This gorgeous puzzle was created and entered into the IPP design competition way back in 2015 where it won a Jury honourable mention award. It has been reviewed by Jerry Loo who really enjoyed the solving. I am not entirely certain how I missed out on this one (I suspect that I ran out of budgeted funds or had been treated with terrible bodily harm by "she who frightens the bejeezus out of me"). I already have the Arrow blocks and the Road blocks already and very much enjoyed them. 

The aim of the puzzle is to convert one to orientation to another:
            1    2                1    2
                           →
            4    3                3    4
There are also several other orders that you can attempt but they are quite a lot simpler (although still a fun challenge). Obviously this cannot be like the traditional 15 puzzle - there is no gap to use to slide the pieces around with. Obviously something has to come out first and I discovered that by turning it over to look at the reverse of the tray: The 4 has no protrusions and then the other pieces can slide. Simple I thunk©, now I slide them into the correct position and reinsert the 4 piece. Of course, our good friend Pit would not have made it that easy - the sliding does move things about but you always get blocked no matter what direction you try. I guess that I had better take all the pieces out?

Now you can see why the puzzle isn't that simple
Maybe the tray needs to be rotated before trying my simple reinsertion? Nope, too easy - the tray just has a slot under the frame all the way around with no obstructions. Time to Think© again - ooh that's painful!

The challenge is not terribly difficult - I think it must have taken me about two hours over a couple of sittings. The lovely thing about this puzzle is that there are 2 very distinct Aha! moments before you can solve it. The first of them I came to quite quickly because whilst I'm not terribly bright, I am not entirely stupid! The second Aha! moment took much longer. I seemed to get fixated on trying one particular thing which was not going to work but I tried anyway...multiple times. Doh! Eventually I had my breakthrough and could count to 4:

I can finally reach 4!
I then brought this wonderful challenge to work where I tortured a few ODPs, nurses and medical students who needed a break from my barrage of information. It was really quite fun to watch them all go through the same process as me. The got fixated on the same problems and eventually had the same Aha! moments (occasionally with a little nudging) and were all delighted with the challenge.

This fabulous puzzle is well worth obtaining and sharing with friends if you can find a copy.



Dale Shows Passion Before Wedding Vows are Allowed

Passion Puzzle by Dale Overy
I have enjoyed Dale's company at many MPPs over the years. He sits quietly solving stuff with ease and enjoys showing off new finds and new creations. He has a particular penchant for disentanglement puzzles which is a delight for me because so few puzzlers seem to really love them. I had purchased a few little toys from him at the last MPP and promptly hidden them when I got home so that Mrs S did not see me moving a bunch of extra toys into the house after a day away. With so much work on my plate, I promptly forgot them and only found them again whilst "she who makes murder hornets fly away in fear" was away.

The Passion puzzle may look very familiar - it looks rather like the classic Wedding Vows puzzle which I reviewed in 2015. The aim is to move 1 bead across to the other side alongside its' lover. Of course, the bead will not fit through any of the holes in the puzzle. There are a number of similar looking puzzles that I have reviewed in the past but they have had very different solution paths. It is definitely not a hugely tough puzzle compared to the monstrosities that I have acquired from Aaron Wang or some of the worst of the sadly missed Livewire company puzzles. But the challenge is really quite fun and, dare I say it, probably suitable for beginners or non puzzlers.

The fun thing for me is the realisation that this lovely challenge is one step before the Wedding vows. You definitely need to go through the Passion puzzle stage before reaching the Wedding vows:

Very clever.
I still have a couple of others to play with from Dale that will keep me jingling and annoying "she who can freeze a lake with just a look". Whack! Ouch!
