Good Puzzling Comes in Three's?

Three Pieces? Or Three Puzzles?
TripTIC
NeuroTIC
You cannot have too many Turning Interlocking Cubes! Especially made by Brian Menold or designed by the "Master of the TIC" - Andrew Crowell. Brian's last update had 4 TICs in it and I picked these 2 because I already had copies of the other two (SkepTIC previously from Brian and remaining unsolved as well as XiTIC from Bernhard:
XiTIC pieces
XiTIC assembled
I really need to find my copy of SkepTIC and solve the damn thing - I seem to remember that I bought it in March last year and could not assemble it and have put it down somewhere - who knows where!
SkepTIC pieces still to be assembled
When Brian offered these puzzles that I did not have in my collection, I could not resist. Well, you all know that I struggle to resist many puzzles that are put on sale and have really annoyed Mrs S by continuously increasing the size of my collection and failing to put them away. She was distinctly unimpressed when they arrived. I had been hoping to intercept their arrival without her noticing whilst I have had a few days of annual leave over the last 2 weeks. Unfortunately, she had me doing DIY and gardening for much of the time off and I couldn't get to the door in time to intercept before she got there. I was wiring in replacement smoke and fire detectors and up a ladder when the package arrived! I nearly fell off the ladder in my haste to get to the door first but she's too damn quick! 

In the evenings after finishing my enforced chores and (for once) not electrocuting myself, I set to playing with these fascinating TICs. The fun thing about both of the new arrivals is that they have only three pieces in each:
TripTIC made from Paduak, Canarywood and Angelique wood
NeuroTIC from mixed woods
I started with the "easy" one, TripTIC, as it only had 2 rotations and 11 moves. and quickly found the end positions for each of the pieces and individually found the rotations but when trying to put all three pieces together the pieces interfered with each other's moves. until I found a very nice little position for one that opened up a hole for the introduction of the other and after about 15 minutes I had a lovely little cube:
See! I can solve the odd puzzle occasionally!
Time to move onto the harder one...NeuroTIC also has 3 pieces but despite having only 2 rotations, it has a higher level of 13.3 and as Brian puts it: "some interesting moves". I definitely struggled on this one. I quickly determined the final resting positions but putting any third piece into the mix quickly blocked me. I couldn't seem to work out which piece to use first and I ended up having to solve this over 2 days. Yes, I forced Mrs S to allow me a little puzzling time during my time off. Whack! Ouch! Sorry dear. As Brian said, there are some really clever moves involved here and the final rotation that allows the rest of the puzzle to slide together is absolutely delightful. 
Absolutely wonderful assembly process
Disassembling the puzzle caused me a little trouble. I got all caught up and had a piece trapped and unable to release it despite working out the correct rotation first. This could easily also be a disassembly puzzle. 

I really never know how to store these puzzles - should I keep them disassembled? Or should I keep them as lovely looking cubes to be taken apart - this would help with storage but decrease the repeatability of the puzzles.

Of course, I couldn't buy just 2 TICs from Brian. I had to make the postage worthwhile - I also couldn't resist a third one being released by him from the amazing Haym Hirsh, the Green T-Box:

Green T-Box

I had already bought the original T-Box by Haym back in December 2021 and thoroughly enjoyed the sole process of packing 6 T-shaped bars into a beautifully designed box so how could I possibly resist a reworking of the original idea with another 6 T's of different dimensions and a different set of obstructions in the box? Again, it was beautifully embellished.

After spending a few minutes trying to rearrange the pieces in vertical positions from the placements they arrive in, I quickly realised that vertical placement was definitely not going to cut it! This one is damned fiddly - the tolerances of the woodwork is astonishing! Even a tiny amount of tilt to a piece will get it wedged in amongst the other pieces and require a frenzied shaking and tapping of the box on your palm to free them up. After ½ an hour of repeated attempts in the box, I had to start to think© outside the box and realised that it was not quite a case of simply shoving the pieces inside in the correct order and orientation. The pieces needed to be placed and some of them slid into position inside. It's a very satisfying feeling when the final piece drops in and the lid fits on top snugly.
Trust me, all the T's are inside
What is next for Brian and Haym? Will we have Black T-Box? Oolong T-box? Who knows! Whatever it is, I will not be able to resist. 

Thank you, Brian for a week of delightful puzzling to take my mind of the DIY and gardening. In fact, I have had quite the roll this last couple of weeks - I look forward to showing the completed puzzles off to you over the next couple of weeks.

The Vault Has No Room Inside

I Get A TIC Trying To Open It

TIC Vault by Andrew Crowell
I sort of knew that this puzzle creation was being developed but had no idea when it would be released. Andrew doesn't seem to market his toys very much and I heard nothing about it. I guess it will have been mentioned on the Discord but I just don't have time to visit it any more than once in a blue moon which probably means that I miss out on a lot of stuff. Luckily for me, at Peter Hajek's End of Year Puzzle Party, the TIC Vault was mentioned in the list of people's favourite puzzles of 2022 six times and  was the favourite for Goetz, who has absolutely impeccable taste that very much overlaps with mine. I contacted him and was told that some were being made and would be available soon and to keep an eye out for when they go on sale. I was very lucky to get one and took delivery at the end of January.

This puzzle is a triumph of 3D printing - it is stunning! The Vault itself is a deep Navy blue and has the characteristic 3D printing layers on it with a black central area circumscribed by a red circle inlay. The sides have very smooth inlaid patterned inserts which break up the layering. It really is pretty attractive and surprisingly heavy - I suspected there might be quite a few magnets embedded in it (one can be seen on the picture above). It is 5x5x2.88 inches in size which upset Mrs S as it will take up even more space that I don't have!  

It arrived with another of Andrew's colourful cards describing the challenge:

1. Unlock the vault
2. Find Your Unique ID Number

Rules: No external tools, excessive force, shaking or spinning is necessary.
Fab, I Thunk! Reach in to the handy gripping sections for the nice quartz finish TIC in the middle. Grab and pull and nope...that ain't coming out of there that easy. Maybe the centre rotates and releases it? Nope! Maybe holding it in different angles or upside down will release it? You guessed it...Nope! My next attempt would involve spinning but that's not allowed/needed. I'm not sure that I want to waste a whole bottle of gin submerging the puzzle and really doubt that Andrew would be that devious. I am obviously missing something. But what?

And here I got stuck all of my first day of playing with it. I tried the same things over and over and over again of course but the answer was still Nope!

Maybe it would work another day? So I left it until the next day and again tried all the same tricks. Still nope!

This went on for 4 days in total and I began to think about tearing my hair out before remembering that I don't have enough to get hold of. I suspected that hair would not play a part in the solution and so I went back to Allard's think©ing trick. It hurt but I remembered a mechanism used previously by other puzzles and tried that. Initially, I tried it in the wrong place but kept at it all over the place and I had found a tool - it looked remarkably like a piece of the cube in the middle. One thing about this tool though...it had a funny shape on the end and a magnet embedded in it - Aha! I needed to try and use this tool next. Fortunately there are only so many places left for using the magnet and I found a couple of areas that caused a clicking noise. Despite a lovely and repeatable clicking noise, nothing else was changing. I could tell that I was going to exhaust my think©ing organ!

I tried something else and got my wonderful Aha! moment and visibility of a clever mechanism that had been used to lock it inside. I now had yet another tool. Now what could I do with that? Removing it had revealed some interesting stuff inside but nothing reachable with the tools I had. I know it's hard to believe but I got stuck again! Yes, being not terribly bright is not very helpful when solving complex puzzles.

After another day or so I noticed something slightly odd and tried to use it in various ways with no luck. But then the earlier clicks suddenly made sense. I had another tool/piece and then finally the cube pieces were all removable. Now I obviously had a TIC - lots of pieces. Lots and lots of pieces which had a very odd feature. Counting the voxels and the fancy features, I realised that something was missing - it was still in the vault and required a simple move to remove it. I had this:

Lots of pieces, lots of magnets and some odd slots
It was immediately clear that the TIC pieces needed assembly first. There were 3 pieces with slots in them and magnets at the end plus 3 pieces that would obviously engage into those slots and lock at the ends. BUT (a very big BUT) which went where? I am absolutely terrible at assembly puzzles and this challenge stumped me for quite a long time. Yes, embarrassingly it took me a week to work it out and get my TIC pieces assembled and then the TIC rearranged into another cube. My excuse for the long challenge is that whilst all the pieces are quite simple, it is quite tough to arrange them into a cube without interlocking them first and I struggled to visualise the shape they would make. Don't look if you don't want to see the assembled cube.


After that it was clear that the cube would interact with the vault (Nothing else was possible with the empty vault and moving the cube around the outside of it or underneath did nothing. I returned the cube to the vault and apart from a huge number of clicking noises, it did not do anything. I was obviously going to have to try other orientations. Was I going to have to try each face down and in 4 different directions? After another little think I had another a realisation that probably attempting 24 different ways to reinsert the cube was not what was intended. I thought, I saw, I conquered and another Aha! moment happened. This was really really clever. I had a coin telling me the puzzle was a TIC Vault but did not have my unique ID. Looking at what I had, a "what if I?" question occurred to me. There was a particular feature of the vault that did not seem to be necessary unless I used it in a certain way.

Aha!
Now that is absolutely wonderful! I had my unique ID and could see how the puzzle worked. It is a masterpiece and I have a candidate for puzzle of the year already! It's looking like 2023 might be a really good year!

All solved - I left my coins outside so will have to solve it again to return them
The reassembly is much easier to complete but still fun. This is an absolutely wonderful puzzle and I will challenge some people at work to play with it if we have any downtime - will go on display with the rest of my ARCPuzzles and be a centrepiece. Thank you Andrew for a wonderful odyssey that took me nearly 2 weeks to complete. Wonderful!

The Burr Bot Took His Gold to the Burr Bank

Burr Bank by Andrew Crowell
I have been home alone for a week whilst "she who must be flinched from" has been oop north visiting the outlaws. You might think that this would be fabulous as I could slob about, eat crap, watch a lot of action movies on the TV and play with my toys! Unfortunately, I still had to work and I had been left a list of chores to do and had to look after a disturbed cat. I am far to frightened of her to leave the place in a filthy state for when she came home so the cleaning etc still had to be done. I did manage to find a little time for some action movies (Dune was a little slow) but I always appreciate a film with Milla Jovovich in it. The puzzling was really rather good as you will read below.

Two weeks ago I wrote about Andrew Crowell's Burr Bot and I absolutely loved it! Unfortunately it is not available any more as Andrew has shifted his attention to the next puzzle in the sequence, the Burr Bank. As far as I can tell, it is not yet available for general sale and my copy is an advance one prior to him making them more widely available. I do not know how many of them will be made because this is a tour de force - Many people seem to think that 3D printed puzzles are easy to make, you just set the machine to go and the puzzle comes out the other end. I know for certain that this is not the case - the design has to be perfected which may necessitate multiple reprinting, the machine settings need to be just right, the finish and infill need to be perfect and, in the case of these, lots of magnets need to be glued in place. The thought and work that has gone into this creation is staggering.

There are no real spoilers here but I have hidden several of the other photos behind spoiler buttons - don't click if you don't want to see.

Just like with Burr Bot, the aim is to open it up and find the hidden treasure inside - in this case it will be gold. Comparing it to the prior creation, this one is obviously significantly more complex. There is the usual four horizontal burr sticks (which I assumed were different form the predecessor) and also the vertical one that interacts with them. Except this time, the vertical one is trapped by a lid with a hole in it. Interesting to see but nothing moves apart from the horizontal sticks so off I go to see what is possible. Just like before, there are quite a few movement possibilities and I was worried that I would get lost (this is always my perpetual fear when playing with complex burr puzzles - I have one of Alfon's puzzles trapped in a halfway position which I cannot get out of).

I needn't have worried, the movements are not so many that I could not keep track. I made a particularly interesting discovery and was able to do it repeatedly and was happy to proceed with the next step. I was able to remove the top panel:




At this point I got a bit overconfident - remembering what had been done with Burr Bot, I attempted to do the same thing...again and again and again! 

Of course, I was too stupid to realise that Mr Crowell was not going to make it easy for me. I got stuck at this point for a couple of days - what I wanted to do just wasn't going to happen and I was too thick to stop and try something else. Eventually, I got fed up with failing and looked properly at what I had and what I could do. There was something obvious to try that I hadn't thought of (did I say already that I am not terribly bright?) and once I thunk it then I had something else to try as a result. 


This is fantastic! I really felt like I had achieved something and still had a long way to go. Looking at the lid and base was no help. There was obviously stuff to be done with them but I couldn't see how it was possible.

Maybe if I went back to what I had been trying and failing at before? Well that was clever - now my impossible aim seemed to be achievable.

Having done the puzzle multiple times now, I have come to realise that Andre has done something rather unexpected with the puzzle sequence. I can't tell you what it is but if you get a copy for yourself and play a few times then you will notice something special about the sequences that are needed. It is an added bonus that made me grin for quite some time.



Once I had feed a fair number of parts of the puzzle and looking at what I had, there seemed to be something obvious that I needed to do. I mean, really really obvious! So I did that obvious thing multiple times without anything happening. Yes, stuck again! At this point it was time for me to think© yet again. I am not good at think©ing and having to do it multiple times during one puzzle solve was pretty painful but quite enjoyable - everything that you need is there in front of you but despite being in plain sight, is not obvious. I noticed something special about one of the pieces and realised that was going to be useful. Also, at one point I did wonder to myself, why do I have two of those when previously I had achieved my procedure using just one of them? (No I can't show them to you) and then the reason hit me in the face. I had to use both of them (it was not because one was spare). 

I tried something doing something for a third time and this time it was useful:

That shark gets everywhere!
The rear of the coin - a ?
Having found the money, I was all flushed with success. Solved a puzzle in time for the blog post this week except...why was the a ? on the back of the money? I also had a nagging thought that maybe it was not the end result that was intended. The pieces that I had did look like there was another area to explore and the instructions (which I had not read since I took the photo a few weeks ago) were clear that the "cantankerous fellow" had hidden gold in the bank. The coin I had found was definitely not gold in colour. Time to think© yet again and maybe find some other tool and way to open the final compartment. It didn't take me much longer but the Aha! moment was wonderful - I had plundered the plastic gold:

Aha!
What an incredible puzzle! There are multiple facets to it with tools to discover and work out how to use. Some parts have wonderful moments of realisation to them only after doing them a few times. Every single corner, plane, flange and magnet has been carefully designed into the puzzling process. Andrew has taken what he learned from Burr Bot and taken every aspect a step or two further. I adore my wooden puzzles but this is something I will treasure for a very long time - despite being plastic, it is still beautiful and is one of the best puzzles that I own. It will be a major contender for puzzle of the year 2022. Thank you, my friend!



Wil Tricks Me!

Aus dem Effeff
Recently I made a rather special purchase from Wil Strijbos and was delighted when there was a little extra gift in the very well taped box. The Aus den EffEff puzzle is a "simple" packing puzzle. A complex shaped hole in the frame in which there are a bunch of Eff's (10 of them). They are dual sided being white on one side and a really vibrant red (presumably Padauk) on the reverse. The instructions are to take all of them out and place all the pieces in place red side up. As you all know, I am terrible at this sort of puzzle but there is something compulsive about it - the pieces fit together nicely and it is strangely therapeutic placing them in the frame so that they lock together. At least it is for the first week!!! 
😱😱😱

I have spent quite a few hours idly trying to put this together and was beginning to wonder whether this was one of those impossible puzzles that I have been a victim of before. I always would get extremely close and yet there was always one voxel in the wrong place:

Almost there but almost is not good enough!
I've been having a little email conversation with the great Michel van Ipenburg recently and he asked how I was getting on. After admitting my total failure he offered a clue - literally an emphasis on a single word did it for me. The solution was obvious if I had tried to actually think© about it but that is not my strong point and it took a little nudge. The aha! moment is delicious and I finally managed to pack the puzzle properly. Wonderful challenge as well!

Can a Robot Choke? Burr Bot by Andrew Crowell

Burr Bot by Andrew Crowell
Before I start today, I have to inform you (if you hadn't noticed already) that the puzzles I reviewed last week have been released for sale on the Pelikan puzzles store. Almost all of them are still available as I type this.

I have known Andrew for a rather long time and have had a LOT of fun with his puzzles over the years. Originally he was known for his gorgeous wooden creations - mostly interlocking puzzles of his own design as well as remakes of a few of his favourite Stewart Coffin puzzles.
Diagonal cube
Locked cube III
I was amazed by the quality and finish from a relative newcomer to the puzzling world at the time. and then it went a little quiet before he burst back onto the world having taken the rarified arena of Turning Interlocking Cubes (TICs) so beloved by me and one of my mentors, Bernhard Schweitzer, totally by storm and designed some of the most amazing puzzles any of us had ever seen. Whilst he still produced a few of his own designs in wood he has moved into 3D printing in a big way and sells them via his store here or through Etsy

I am always looking for more beautiful wood but I still love the puzzling experience in plastic but tend not to put many of these on display. The advantage of the plastic is that I can box them up and store them in my garage and then play with them again at a later date without having to worry that they might degrade in storage. Today's puzzle will definitely not be going into storage now that I have solved it - it will go on display in one of my cabinets - it is a stunning puzzle in looks as well as play experience. The Burr Bot came to my attention when it appeared in the IPP design competition last year. Unfortunately due to this pesky virus thing, we couldn't all get together and play with them and the viewing and voting was done on-line. I was very intrigued - it was a sequential discovery puzzle as well as a burr. It also won a Jury Honourable mention prize. I was determined to get a copy. 

At this time work caught up with me - the virus was running riot through the UK and hospitals were chock-a-block. My workload went through the roof and I had very little time for puzzling, let alone purchasing. I completely forgot about it until my friend Steve reviewed it (along with a rather wonderful looking cocktail) on his blog. If Steve professes to loving a burr then there must be something very special and/or very clever about it...he will be the first to admit that burrs are not his thing. As you all know, they really are my thing. So I wrote an email to Andrew asking if one might still be available. To my shame, I wasn't paying proper attention to my email app and sent the email to Andrew Coles (owner of the puzzle lock company) who delightfully was obviously used to this mistake happening and forwarded it on to the correct Andrew. Phew!

Before you head off to ask Andrew for your own copy of Burr Bot, I have to sadly inform you that they have sold out and Andrew has moved on to the next in his puzzle series. I was just in time because he had a few parts still lying around and was happy to print the pieces that he needed to complete the remainder of the puzzle. Lucky me! In fact he also offered (whilst he was posting to the UK) to make and send me the puzzle he has switched his attention to - Burr Bank which is supposed to be more complex and the next step in the evolution of this puzzle sequence. Well it would be rude to turn him down so I risked the wrath of Mrs S and both puzzles were being made and arrived a couple of weeks ago.

That week was quite a busy week for Mrs S and the various postal services as I also received the latest delivery from Jakub with the Pelikan puzzles to review, a gorgeous pair of puzzles from Stephan Baumegger as well as a lovely heavy metal delivery from Mr Strijbos. I won't say what she said when my delivery from Mr Fuller arrived this week. Let's leave it at Whack! Ouch! Sorry dear. Let it be known that whilst I apologised for so many arrivals, I did NOT promise not to buy any more.

My work has become quite chaotic over the last few weeks and months. There is a lot of staff sickness in hospitals just now due to Covid and this is placing a lot of strain on services. I spend my time trying very hard to get the work done and help my colleagues clear the enormous backlog of cases that have built up and often finish work late. I also am the fool who volunteered to write the on-call rotas for our department and am having to scrabble around on a weekly (if not daily) basis to fill suddenly opened gaps caused by sickness. Al of this does not leave me much time for puzzling and when I do have time, leaves me with a brain that doesn't seem work right. It was with considerable trepidation that I picked up Burr Bot and read the instructions. 

The cute cubic bot had swallowed something and it was definitely audible when gently shaken. There was no other information so I assumed that it was just a burr that I needed to dismantle. Looking at it I could see 4 horizontal sticks in the frame which would interact with what looked like a vertical central burrstick. Time to investigate and see how they interact. Whilst I love this sort of puzzle and have a MASSIVE collection of these interlocking cubes from Alfons Eyckmans, I do often really struggle to solve them due to getting terribly lost. 

There certainly is an interesting mechanism inside - I got a clue to this when I picked it up from my armchair and the key to the Popplock T13 was hanging from the bottom! There appear to be magnets inside!

Within a few moves!
I quickly became engrossed and realised that there was more to this than met the eye. The central piece rises up but the bottom piece is not attached to it. Whilst that was distracting, I did not know what else I could do and just carried on exploring. One evening in front of the TV left me going round and round in circles with the pieces quite well trapped amongst each other. I had to be careful not to be too noisy - 3D printed puzzles do make a certain scratchy noise when the pieces are moved and I did not want to upset "she who must be flinched from". I was also making lots of my usual muttering noises which she also finds very annoying ("Do you have to breathe like that?" I often hear). I got stuck that first evening but had a breakthrough the following one:

I had a key piece - now what? I got sidetracked trying to remove the cross pieces for an evening before abandoning that as fruitless. There are clearly magnets in it (both the interior of the Bot as well as the key) and it was going to be important to work out how they should be used.

Mrs S was very amused to see me rotating and spinning the bot whilst trying to stroke various parts of it with the magnets. Nope! That was not working for me - time to Think© - ouch!

At this point, I noticed something (no I can't tell you what it is) and this led very nicely to another discovery and then some experimentation produced a whole new challenge. I was off again. 

The remainder of the puzzle required more discoveries, more think©ing and more experimentation - I got quite good at manipulating the burr sticks during this and only got trapped 4 or 5 times. After my 7th or 8th Aha! moments I was finally able to cure Burr Bot's indigestion - it's a kind of radical way to do it (similar to what I see at work many days). In medical terms we have had a laparotomy (opening the abdomen), gastrotomy (opening the stomach), before delivery of the unwanted contents.

Not a spoiler - it was always obvious this was going to happen
It would appear that Burr Bot has swallowed a shark. No wonder he was feeling a little under the weather! At this point, I did think I had finished but there was still some unused parts of the puzzle and something was still gently rattling. After the next step (which I did wonder whether he would survive) I also had the coin that keeps his heart beating:

So much fun!
Time to take the photos and then reassemble it all before trying again to make sure that I properly understood it. A mark of a thoughtful design here, is that the reset of this wonderful puzzle is not just a reversal of every step that has been done so far. It can be reset very easily and then just needs a reinsertion of the key into the top. Fabulous!

I am very grateful to Andrew for finding the spare parts lying around to make me a copy. I can see why he won a prize in the design competition - it is a wonderful odyssey with personality and fun as well as a really nice sequence of discoveries, experimentation and thought. I am looking forward to working on Burr Bank which is supposed to be even tougher and more fun.

Thank you, my friend!

An Entirely New Type of Puzzle?

The recent collaboration between Chris Lohe and Andrew Crowell
Last week's post showed off the recent releases from Jakub and Jaroslav at the New Pelikan Workshop and I am pleased to see that many of you did read my drivel and have bought the wonderful new toys when they went up for sale. In fact two items are sold out already (if you did miss out on anything then I am sure that they will eventually be stocked by PuzzleMaster). I received all 7 of the puzzles and I am always very aware that Jakub is waiting for my reviews before he puts them up for sale so the pressure to solve and write is very high. Luckily for me this time there were two of the batch that were sent to the Zen puzzler himself, Ken Irvine, for review and I did not have to be too fast with these. Ken is a master of the design and solution of interlocking puzzles and is very uniquely placed to give an opinion of the two beautiful lumps of wood and if you read the blurb on the Pelikan site on them, then you already know that Ken was extremely enthusiastic. I did, however, really want to try them and give an opinion for you all (even if I am not sure why you even read my stuff let alone pay attention to what I think).

First of all, let me say that these puzzles are absolutely amazing and you should buy them straight away - unfortunately the Cyburr has sold out already but in my opinion the Chamburr is the best of the two and certainly MUCH more difficult. Stop reading this right now and rush over and buy - you will not regret it.

I have waxed lyrical about Christoph Lohe and his designs many many times over the years - he has a very unique talent for designing puzzles that are just the right difficulty level and really interesting to solve with some very long and difficult to find sequences but always fun to work through - he is almost a savant. Then we are all aware of the incredible effect that Andrew Crowell has had on the puzzle world. He has taken the rather small rarified area of Turning Interlocking Cubes (TICs) into the stratosphere in terms of interest and difficulty. So...when these two incredible puzzle designers team up I just have to sit up and pay attention! This is should definitely prove to be something simply spectacular and YES it is incredible - it is almost like they have developed a whole new category where the interlocking puzzle is combined with the TIC without making something that is impossible for humans.

Cyburr
Starting with Cyburr (this is the one you should pick up first), we have a gorgeous cube made with a Mahogany frame and Maple burr sticks. It has been beautifully finished and the initial moves are buttery smooth. There are a number of choices possible at the beginning and quickly you can home in on the correct path. Some puzzles I find are spoiled by having too many blind ends or some that go much too far before petering out. I like a fascinating sequence with a few side paths to explore but not too much risk of getting hopelessly lost. During the pathway through this disassembly, there is a wonderful dance as the pieces are weaved around each other inexorably towards an exit. The exit this time seems possible at several times as the burr sticks get less and less interwoven but even when one is separated from the pack then it still cannot be simply pushed out. This is where Andrew's wonderful skill has come in...rotations are required. Not too many that it is possible to get hopelessly lost and entangled. He has designed it so that rotations are actually very difficult to achieve and are only possible with exact positioning of all 3 of the pieces within the frame. This is not going to happen by accident - it requires thought©. The Aha! moment is wonderful. Two rotations are required and the pieces are ready for your exultant photo:

Stunning precision on that craftsmanship
The reassembly is a serious challenge! This puzzle cannot be solved by Burrtools but the process of disassembly should take you back and forth enough to lay down a decent muscle memory to allow you to scramble the pieces and still be able to put it back together again. If I can do it then all of you (who are considerably cleverer than me should manage it). I do agree with Ken that this puzzle is probably too difficult to be sent out as pieces to be assembled from scratch - only a very few of us could manage that. The Cyburr has a sequence 38 moves to remove the first piece which is a prodigiously high number especially as 36 are linear before the first rotation is required. If you see this up for sale again then buy it!

Chamburr
Next up is the Chamburr (I am not sure why it is named this but for me this is the "Champagne of the interlocking cubes" - it is stunningly fun and really quite a tough challenge. I did not know at the time that this was the harder of the two and this was the one that I started with. Again it is beautiful with the frame made from Merbau and the three burr sticks made from a lovely warm Pink Oak. It is slightly less aesthetically pleasing than Cyburr purely because it doesn't have the completely filled face that the other does. But it is stunning. The movements of the pieces are smooth and again there is just the right number and depth of dead ends to explore. The Chamburr is slightly easier at the beginning than the Cyburr but gets MUCH more difficult about ⅔ of the way through. With both of these puzzles, Pelikan has made all of the internal edges of the burr sticks and the frames very sharp which I suspect is to prevent any illegal rotations being found but the adverse effect of this is that finding some of the linear moves can be quite hard as the pieces need to be held just right and everything lined up perfectly for them to slide on each other. This can be a little infuriating at first but it does mean that finding the linear moves is more than just pushing and pulling the pieces randomly. It is more that the moves need to be thought out and planned. After 10 or 15 minutes of play with each of these puzzles I came to appreciate the precision and sharpness of these edges and used them to my advantage.

The Chamburr has a couple of very interesting rotations that are possible at about the ¾-way mark and apart from a bit of a panic when I thought I couldn't undo them, I realised that this made for a fun dead end and quite a bit more exploration without risking getting lost. After realising my misstep, I continued. The linear part of the path for this one is VERY complex and several times I got to a point where I could not backtrack without a huge re-exploration of that part of the path. I must have gone back and forth over that section of the solution 10 or 15 times before I understood the dance path of the pieces and could repeat them easily. After 43 moves (amazingly, all of which are linear) the first piece can be removed. This is a stunning odyssey before the remaining pieces can be taken out of the frame with a rotation:

43 moves to take the first piece out!
Despite the fact that the initial part of the solution is linear, this is by far the toughest of the two. It is incredibly difficult to find your winding path through the moves - these pieces dance about in and out of each other and the frame but the pathway is really well hidden. The requirement for the rotations is the icing on the cake - it makes the puzzle constructable and also means that if you get stuck you cannot just go to Burrtools and make yourself a solution file. You HAVE to persevere with it and work it out. It is worth it - just keep trying and you will understand it eventually.

Reassembly is just as challenging - the rotations are easy to find but then you have to backtrack through that very well hidden pathway. It took me several hours over 2 evenings to get there. This is a candidate for one of the puzzles of the year for 2021 - AMAZING!

At the moment the Chamburr is still available here - buy it straight away and if you find Cyburr up for sale again then don't hesitate.

Celebrating 10 Years Helped By Pelikan Puzzles

The upcoming release from Pelikan
I am going to start today's blog post all sentimental and maudlin. If Allard can do it then certainly I can too - I am MUCH more of a sentimental fool than him. Yesterday was the 10th anniversary of my very first post on this blog. It was really just an announcement of an intention to write about puzzles and then the following day (14th March 2011) was my very first puzzle related article and I started with something special - the original Revomaze series. It was these gorgeous lumps of heavy metal that got me hooked. I needed to find a way to take my mind off an unexpected near death experience and these were it. Of course, any true bloke who gets interested in a new toy will take to the forums and those bastards lovely ladies and gentlemen got me hooked on more and more puzzles. Within a few months they had forced me into taking the huge leap to my first really "expensive" puzzle (Tom Lensch's version of the Mazeburr). Yes, I was hooked! I wanted to publish at least once a week until I either ran out of puzzles, ran out of steam or Mrs S murdered me and I have actually managed that for 10 whole years (Mrs S really has come close to ending the blog though). Initially I was publishing 2 or even 3 times a week but that gradually settled down to my usual weekly schedule. I had been advised by a blogging guru to set a schedule and stick to it - apparently your readers have certain expectations and you should try not to disappoint them. Indeed on a few occasions if I dared to be late then I would get an email asking if everything was Ok and where was their weekend reading? I settled into a routine and have managed to write something every week apart from on 2 occasions - I think I can be forgiven for missing the day after my mother died and also last year when I was really ill with Covid having caught it at work. 

In this 10 years, bloggers have come and gone but the people/puzzlers behind them all remain - this is just a hobby and people have to live their lives. I am very proud to stand alongside Allard in completing 10 years of entertainment for the community. In that time there have been 619 posts on my main site plus 138 on the associated New additions page (this was the only way Blogger would let me set up a separate page) and my pageviews ramped up quite quickly. As of publication today I have received 1.9 million pageviews and now that so many have occured after my mother died I can now convince myself it wasn't just all her. My most viewed posts are on the Hanayama Cast Quartet at 23,300 views followed by my post about twisty puzzle parity at 22,800 views.

Puzzlemad New stuff page
I was achieving 10-15,000 views per month but the last 15 months have seen a sudden increase to 30,000! Unbelievable that so many crazy people out there want to read my drivel! My readership is truly global which boggles my tiny mind. 
What happened at the end of 2019?
It has been the community out there who has kept me going. The trouble with blogging is that it is a huge effort to do this week in and week out and it often feels that you are shouting out into the void. Over the years many of you have contacted me or left comments on my posts as well as been in touch via my personal Facebook page. It is those moments of contact and feedback that make it all worthwhile. I do not try to monetise this hobby - I  gratefully receive a few $CAD each month from PuzzleMaster if you buy from them via a link on my site but that is the only income I get. To be honest, I am not really interested in the idea of earning money from my hobby. I am lucky enough to work in a position where my income is secure and I want this to remain a hobby. I have turned down offers of sponsored posts, advertising and SEO posts. For me, this should be all MY work. Except (and it's a very BIG exception) for the guest posts provided for me by my wonderful friend and foreign correspondent, Mike Desilets. He has come up with the goods for me when I was either too busy or had nothing prepared. I also like to think that he provides a great view of an alternative side to this hobby. He certainly collects, solves and writes about modern puzzles but primarily he has shown off the more vintage side that I have very little knowledge of. I am exceptionally grateful to him for all his efforts on my/our behalf.

The desk is out of control! She says I MUST tidy up!
I hope to continue this wonderful hobby of puzzling and blogging for another 10 years at least as long as you will keep reading and as long as Mrs S will let me. I have a serious space problem - and have rearranged my collection many times and expanded from one small study into another room. When I mention taking over another room, the laser burning stare moves to between my eyes and I can smell/feel burning coming from my forehead. The conversation closes abruptly at that point! 

Now on to today's puzzle reviews. For my tenth anniversary post, I am so pleased to have received early copies of the upcoming releases from Jakub and Jaroslav at Pelikan puzzles. This particular batch is absolutely stunning and has some really special and unusual puzzles in it.

Pepper Castor

Top view
Bottom - the pepper casting view
This beautiful puzzle screamed at me to be tried first. It's a design by Alexander Magyarics, it's beautiful in Zebrano and Padauk and most importantly it's based on a triangular grid. Very few puzzle designs (other than 2D packing puzzles are very made using a triangular grid. I suspect that this is primarily because it is harder to design them with it being very hard to tell during the design process whether there will be unwanted rotational shortcuts. Also there are very few craftsmen willing to put in the time and effort to make the required jigs to these accurately. Here we have the perfect combination of a talented designer who has obviously done his homework and ensured there are no shortcuts as well as some of the best craftsmen in the world!

This puzzle is named after the pepper shaker/castor because of the pattern of holes on one end and it quickly becomes apparent that they are there for a reason. My first reaction during my early moves was that this was seriously fiddly. Then I realised that changing the orientation of the puzzle made certain moves easier to control and then I discovered that after 3 or 4 moves, my ability to backtrack was gone! I was stuck with a piece packing out and unable to visualise the internals to reset it. Oh well! Better carry on then. After about a ½ hour of progressively more anxious swearing, I removed the first piece and then the other two. There was no Aha! Moment as I had no idea how I had achieved it. I took my photo and realised that I had scrambled the pieces! At this point, it became quite apparent that this puzzle is a very special variant on the usual Magyarics theme... he had created a fancy low piece number interlocking packing puzzle. Very similar to many of his others but with the twist of a triangular grid and holes top and bottom.

Incredible pieces!
Repacking was a serious challenge, first reproducing the shape to fill all the gaps in the box and then working out the sequence. Finally actually having the dexterity to do it was a nice added bonus. This is a terrific puzzle as well as a gorgeous one!

Rattlesnake

Rattlesnake - you can see why
No release from Pelikan these days is complete without another wonderful packing puzzle from Alexander Magyarics. This beauty is stunning with a Wenge box complete with fairly large but quite restricted opening and 3 pieces to be placed inside made from Zebrano. As usual, the question I always ask myself is:

"there are only 3 pieces...how hard can this be?"

Well, either I am stupid (probable) or this one has a serious challenge to it (quite likely). Several times I tried to get 2 pieces inside the box only to have one rotate inside and then block all other movements. Nearly gave me a heart attack at one point when I couldn't take the pieces out that I had placed in the wrong positions!

Not only is the opening fairly restrictive but the shape of the rattlesnake piece also ensures that the approach to insertion is very limited. In fact, there are only 4 orientations of that piece that will allow it to be inserted. What is more, the medium sized piece only has 7 possible insertion methods. I tried to be fairly methodical and realised quite quickly that I was unable to keep track of the possible combinations. Starting with that large piece, I ended up randomly looking at assemblies that sort of fit the 3x3 cube and discarded the ones that the second piece could not be inserted. This gave me quite a few possible assemblies which I made outside the box and then tried to simulate the disassembly. This took me several hours because I got fixated on one particular orientation of the snake which looked fantastic but would not assemble in place. Time to Think© again! Getting past my fixation proved a real challenge. I found another series of very nice assemblies but could not seem to get them to work until Aha! There was a wonderful moment when I noticed a possible move that is very very well disguised. I had worked it out. Getting the pieces into the box was then a bit of a dexterity puzzle as well. This is wonderful, right up there with the very best of Alexander's designs. It looks so simple but really takes some thought.

Brilliant!

Sliders

Now that is a complex construction!
I'm sure by now you all know that I adore the 3x3 cube based packing puzzles with unusual piece shapes and restricted entry into the container. I have lots of them from Osanori and Alexander and am always in the lookout for new variants. Imagine, if you will, yet another one, beautifully made by the guys at Pelikan but making things much more interesting the box has captive pieces which hook over two of the sides which can slide into any of the three positions on each of them. This means we have a similar type of packing puzzles but where the box can effectively change shape before and during the solution process. It also means that we have seven challenges where the "sliders" have to end up at different positions (the eighth potential configuration has no solutions). This is a puzzler's dream - beauty and multiple puzzles in one. It has been superbly constructed with a gorgeous Pink Oak box, Wenge captive sliding pieces and vibrant Purpleheart pieces.

These seven challenges are definitely not trivial, in fact I've only managed to solve 3 of them so far. I don't think that I have found the "best/longest" solution to them so I will have to keep looking. This one definitely needs to be solved outside first before attempting to fit it inside - but the captive sliding pieces make the thought processes much more difficult. This puzzle is absolutely fabulous and great value for money - go buy it now!

First challenge solved - YAY!

Akku

Akku - looks formidable straight away!
Dr Volker Latussek has been providing some fabulous puzzles to Pelikan for a few years now. They are all extremely clever and challenging - some so clever and challenging that they are beyond my abilities (blush, Euklid for Nick remains unsolved). In this release we have Akku (I am not sure why the German word for battery is the name of this puzzle - maybe Dr Latussek will comment below). This consist of a wonderful Acacia box and some very precisely crafted Maple pieces to be packed inside. There are 9 L shaped pieces to be fitted into the interior of the box. The cavity is 4x4x3 units in size and each L is 3x3x1 unit meaning that there will be just 3 holes in the packed puzzle but with such a large awkward shape the assembly will need some rotations to get the pieces into the restricted opening.

This is how it arrived - I cannot put it back this way!
The puzzle is shipped in a special shape that Dr Latussek instructed and I took the pieces out of the box for the photo only to find that I could not get them back into that shape again! This was going to be a foreboding of what was to come. I spent quite a while trying to find how to assemble a 4x4x3 cuboid from these pieces and even this was a struggle. In the end I resorted to Burrtools to try and find the possible arrangements - there are 6 ways to assemble the shape. Time to pick one and get it into the box. Easier said than done! This is a serious puzzling challenge. After 2 evenings of attempts, I finally worked it out - wonderful idea. Think of how best to rotate an L shaped piece and then see what you can do with it. My solved picture is behind a spoiler button - it doesn't give a lot away but there is some info in the picture that might give more of a hint than you want - you have been warned! Don't click the button!

Fake Cube

Fake Cube - this is beautiful and looks impossible
This glorious work of art has been made from Acacia and Padauk. The aim is to assemble the complex pieces into a cube shape which can be stood on its' corner in the stand - these 10 identical and oddly shaped pieces need to assemble into a 6x6x6 cube. Just doing the simple maths tells me that this doesn't add up - each piece is 18 voxels in volume  with 10 of them making 180 voxels in total and the 6x6x6 cube will be 216 voxels - quite a large discrepancy. Hence the name...the Fake cube needs to be assembled so that just the exterior looks like it is complete and hides the holes inside and on the walls adjacent to the case. This reminds me of a stunningly beautiful and much more complex version of the Half-cube puzzles from Vinco. Yet again, I removed all the pieces for my photo and couldn't put them back into the packing position (I love how all of his puzzles have a specific arrangement for transport). I have not had long enough to play with this puzzle - I have managed (by pure luck) to make a shape that will fit into the case but clearly not correct as there are lots of holes visible on all sides:

I'm fairly certain there shouldn't be gaps there
The more that you play with this the more compelling it becomes. Initially it seems to be quite unintuitive and a whole lot of random trial and error but as I played I realised that the way the pieces fit together was extremely constrained and I needed to work with this constraint to create at least 3 complete faces and 8 (out 12) complete edges which would be visible. in the case once complete. Easier said than done! I have not had enough time yet to solve this one but I think with a few more hours of trying I will get there. It is a seriously difficult assembly/packing puzzle but like most of Dr Latussek's creations, it can be solved more with thought than trial and error. For once I am hoping that my thinking© might actually help here.

Chamburr

Chamburr
I have not yet had time to play with this one and will review it properly as soon as I have. When the "TIC master", Andrew Crowell gets together with the master of interesting interlocking shapes, Christoph Lohe then I have to pay attention! These puzzles are very reminiscent of several of the best interlocking puzzles of all time (Lucida and Identical twins by Osanori) but almost certainly are going to be significantly tougher to solve. Chamburr is made from Merbau and Pink Oak and looks fabulous with Pelikan's usual perfect accuracy.

Cyburr

Cyburr
Another that I haven't yet played with. Like Chamburr, it is a collaboration by Andrew Crowell and Christoph Lohe but this time made from Mahogany and Maple. The aim is to separate the pieces from the complex frame and I have no doubt that it will involve some complex rotations in the process.

 

On loan from Shane
Just a quick (and not terribly happy) sidenote. Not everyone in this community is great - I am incredibly proud to have in my collection the complete set of Hales puzzles and they form a centrepiece in my collection. I am very aware that these are effectively just on loan as the agreement with all of Shane's puzzles is that they should never be sold and should be returned to the creator when no longer required. It would appear that there is one deceptive person who has been skirting the edge of the community for a few years and due to his terrible behaviour has been shunned by pretty much everyone. If you want to learn some new interesting swearwords then ask Eric Fuller about Niko. Niko uses a number of aliases and has duped puzzlers and craftsmen into giving or selling cheap and has even tried to hack Eric's site. He has a blog which is pretty rubbish and uses it to deceive quite a few naïve puzzle creators into giving him copies of their creations which he has then flogged at huge profit. He has now managed to con a holder of Shane's Viper puzzle out of someone when they were at a low point in their life and has put it up for sale at an exorbitant price.

Please do NOT buy this puzzle from him - he is an untrustworthy conman and does not own that puzzle to sell - Shane wants it back. If you are contacted by him then just refuse to continue to speak to him. He has several names that he uses including first names of Niko, Nick or Nicholas and surnames of Azerty, Nicolas or Demarquez. He is not worth your time - all of us puzzle bloggers have ceased contact, he has been banned from all the auction sites and most craftsmen including Eric and Wil Strijbos are refusing to deal with him. This says it all!
