Pelikan Summer Bonanza Part 1

Upcoming release from Pelikan puzzles
Thank heavens for Jakub and Jaroslav and team! I have received quite a few fabulous puzzles over the last few weeks and thought that I had lost my mojo (yet again!). I had not managed to solve very much at all and for some of the recent arrivals, I had not even managed to find the first move! I must be really dim! Then along comes Jakub with a beautiful package of 6 lovely puzzles giving me at least a hope of solving a few of them. I cannot do it all in a week and so have split the reviews over this week and next.

In the picture above starting at back left:

Kamelle by Volker Latussek

3 Candles by Osanori Yamamoto
Commotion by Tyler Hudson
Brick Wall by Lucie Pauwels

Jakub has been slightly worried about the fact that some of the creations are not selling as well as he would hope and wondered why. Whilst I adore burrs, I am aware that many puzzlers don't love them and prefer a different challenge. The puzzles in this release are a bit different from the usual and hopefully will be of interest to all you addicts out there. There is one burr but even this is different to the usual.

Commotion

Commotion by Tyler Hudson
Tyler has been quietly working in the background designing very interesting puzzles. They have tended to be various burrs or maze type interlocking puzzles and all have been really good. Certainly they have been good enough for the guys at Pelikan to mass produce and they have always sold out. This one is something totally new and an absolute delight. When it arrived, I took all 5 pieces out of the tray and wondered what I was supposed to do with it. I had to ask Jakub for instructions and Tyler also chipped in to tell me. My initial photo had been with the pieces removed and I had no idea how they had been arranged. 

I was instructed to reassemble it in the above conformation (Tray made from Garapa, 4 flower petals made from Wenge and leaves made from Padauk - it is really quite vibrant). There is a small gap in the tray at the top left and an obstruction to right. The aim is to slide the pieces around in the tray ending with the removal of the red leaves through that gap. 

I tend not to be a huge fan of the usual run-of-the-mill sliding piece puzzles because they end up being a huge amount of toil and trial and error. I usually solve them but in many times the number of moves that is the optimal. This creation by Tyler is totally different to these classic sliders. There is not a set move number to aim for - the challenge is being able to remove the piece at all! The movements can get really very restricted due to the size and shape of the pieces and some of the moves are coordinate motion (something I have not seen in one of these before) and a fair number of rotational moves involving one or more pieces simultaneously.

This was the first puzzle from the batch that I started with and really struggled for quite some time as it locked up again and again. Each time I backtracked and tried something different and found a new path opening up and sometimes being able to take it further. It took me 2 days of real concerted effort to find what I needed and removed the piece. This is an absolutely wonderful new take on a classic genre and is a significant challenge. Well worth buying when it goes on sale.

3 Candles

3 Candles by Osanori Yamamoto
Osanori-san features very heavily in this blog! He is an incredible designer - so much so that Pelikan use one of his creations in almost every single release. He specialises in packing puzzles with limited entry boxes but has designed in many other categories. This one is something rather special and fun. It is absolutely perfect for a puzzler of any level. I guess that I could now be considered an experienced puzzler (even if I am not very good at them) and this challenge really enticed me and I found it to be great fun.

Jakub and team have made the 6 pieces in this puzzle from a lovely rich and deeply grained Merbau with a single block of Maple. Initially, I thought this was a version of the Soma cube but the pieces are larger and there appear to be 28 voxels in total (one more than in the Soma cube's 3x3x3 requirement). I again, had to ask for instructions and was told that these pieces can be assembled into a cube with a single voxel protrusion and the aim was to do this with the protrusion being the white Maple cubie - the flame of the candle. There are 3 challenges for this puzzle: that flame can be in one of three different positions - centre, edge, corner.

I am not particularly good at assembling shapes from polyominoes - the Soma cube still is difficult for me despite having many solutions and I have so far completely failed to solve the Sisu puzzle from the last release (it is still in stock if you want a challenge). This challenge really gripped me - the premise is so simple and there is a major clue to start off with knowing the position of the flame. It is still a fabulous challenge which took me several hours before I had found all 3 solutions.

3 possible solutions
This, again, was so different to Osanori-san's other challenges and so accessible that it is a no-brainer purchase. Perfect to challenge yourself as a puzzle addict or to challenge e the significant others in your life.

Brick Wall

Puzzle face
Storage tray face
I have been watching Lucie Pauwels' designs with great interest over the years. She seems to create them in her head using simple home-made blocks and always manages to produce puzzles that are very different to those of the other designers out there today. There does not seem to be a computer used in the design process and this means that the puzzles that she creates are human solvable and require proper thought and logic to do so.

The Brick wall is a chunky puzzle (20.5x15x3cm) made from a gorgeous vibrant Bubinga and Maple. The reverse side of the puzzle is a tray which holds the pieces (Maple) which are to be the grout in the tiled wall. There are 11 differently shaped pieces of grout which need to be assembled inside the wall. The premise is very simple but the actual solution is not. I started as I always do with a random insertion of pieces in positions that looked good. With Lucie's puzzles, this approach really doesn't tend to work well and it ended for me several times with an almost, but not good enough assembly:

Well that didn't work
After a whole 2 days of failure, I decide that it was time to think© and use some logic. The pieces are shaped in such a way that there can be only one solution and the best way to go about it is to restrict the positioning of a certain few pieces from the very beginning. Once that has been done, the sequence for insertion is really pretty logical - there is a little trial and error where a piece has a little vertical symmetry but it only requires a quick test to see which way around it goes to allow other pieces in.

Despite the fact that this looks like an impossible trial and error challenge, believe me, it is not. Like most of Lucie's puzzles, this is a test of logic which you will really enjoy once you have decided to go that path. It will also look absolutely gorgeous on display.


That is it for this week - hopefully I can solve the other 3 for next weekend. There is a very challenging puzzle from Alfons Eyckmans and also something ferociously tough from Dr Volker Latussek. I know they are tough because it took me ½ an hour just to remove the pieces from the delivery configuration in the boxes! 
The upcoming puzzles will probably go on sale after 16th June.

A Puzzling Tribute to Christoph Lohe

Very sad news
After my last post (about Christoph Lohe's marvellous design, Neighburr) I received an email from both Laszlo Molnar and Goetz Schwandtner with the very sad news that Christoph had sadly passed away at the end of January this year. It would appear that his family had not had contact with him for a  few days and contacted the police and he was found in his flat. It has been judged to be natural causes. As many of us puzzlers are getting older this sort of thing should not come as a shock but he was only 65 years old. I guess that with what I do for a living, I should not be that surprised.

He was a significant scientist having  received a MSc in Experimental Physics from the Technology University Aachen in 1989 and a PhD in 1993. He worked as a Product manager Ferrofluidics, Nuertingen, Germany, 1996-2000. Project manager Aixtron AG, Aachen, since 2001. As a scientist of note he had been listed as a noteworthy physicist by Marquis Who's Who.

I considered Christoph a friend. We had never met and I was not constantly in touch with him but we exchanged emails every few months to discuss puzzles and his wonderful designs. You can still buy some of them from PuzzleMaster here or print them yourself from Thingiverse here.

His amazing skill as a designer is shown by the fact that I have reviewed 20 of his wonderful designs here on my little section of t'internet. I thought that it would be a nice think to look back at a few of my absolute favourite of his designs. 

Collaboration with the TICMaster, Andrew Crowell
Cyburr and Chamburr from Pelikan
Climburr from Matt Nedeljko               
When the first 2 came out from Pelikan, I wondered whether these two masters of puzzle design had created a completely new type of puzzle and raved about them. They made my top 10(ish) in 2021. The Climburr was felt to be too difficult to produce in wood by Jakub and it was only when Matt Nedeljkogot the courage to attempt them did we get to attempt the final one in the series. Spoiler alert - it was fabulous and made the top ten in the next year.

Locks, Locks, Locks!
Burrlock E
Key Trap
Christoph had a bit of a thing about locks and keys but not in the classical sense. He designed burrs in that shape. The fun thing is that rather than make simple 6 piece burrs where the pieces interact in the 3 axes, Christoph made the burrs with a frame to restrict movement and a key and shackle (and pieces) to lock up in at least 2 of the axes. The one amazing thing about all of Christoph's designs is that they are not terribly high level but are always challenging and fun without being too arduous. I absolutely adored these. The fact that even the late Eric Fuller thought well enough of these to make one of them, does show how good they were.

Framed Burrs
I adore a burr that has just the standard 6 pieces but is constrained in its movement and interaction by the presence of a frame. It makes them so much more interesting.

Neighburr by Brian Menold
Bouquet
Castle
Timburr
Again, we have puzzles that are so good that both Jakub and Brian Menold decided they were worth putting the effort into manufacturing in reasonable numbers. They all had something special and were all great fun without being too difficult.

Unconventional packing puzzles
Whenever I think of this particular type of challenge the names that always spring to mind are the incredible Alexander Magyarics and Osanori Yamamoto. But they were not alone, Christoph also had a fascination with these and designed some amazing puzzles:

Liliput
Trenta
Box with 2 balls
Kamelle Box
This is only a few of his great contributions to the puzzling world as well as to my collection but they include my favourites.

Do you have any favourites that you think should be given special mention? If so then please leave a comment below.

Rest in peace Christoph - I was proud to call you a friend.

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.

Truly Something to Behold

Soon to be released by Pelikan
At  the beginning of the week before last I took delivery of a VERY large box from Jakub and Jaroslav containing 7 puzzles and a request to have reviews as quickly as possible. I am just human and with my simple brain cannot possibly solve all of these in that short time (especially when you realise that there are hundreds of challenges here and some are really very difficult indeed.

Here we have:
Back row:
    Matchbox Playground - an extension of Oskar's original design by Péter Gál
Middle row:
    Filling V by Dr Volker Latussek
    Flummox by Benjamin Heidt
    Appletree by Benjamin Heidt
Front Row:
    Parallel Burr Cube #2 by Osanori Yamamoto
    Rattle Twist Duo by Osanori Yamamoto
    MRI by Benjamin Heidt

My picture does not do justice to the beauty and quality of them all (for that, you should wait for the official photos from Ivan Danik which appear on the Pelikan site.

Pelikan 2024 Feb

Stunning series this time with what looks like one of the most gorgeous puzzle sets I’ve ever seen.

Filling V 

Fillin V by Volker Latussek
Sent with just the triomino left out

Dr Latussek returns to challenge us with another of his wonderful packing puzzles that look much easier than they actually are. This one made of ????? comprises 6 L tetrominoes plus an L Triomino giving us the required 27 voxels to make up a solid cube. I could instantly see that there were several ways to make the cube and each of these could be attempted in several orientations with respect to the box. This box has a nice large slotted entry hole which looks like it shouldn’t be much of a hindrance to inserting the pieces. Dr Latussek said this:

"While working on the FLOP series, I had some fun working with completely filled boxes. I ‘d already done some preliminary work using L-shaped tetracubes, so it made sense to me to work on Lazlo Molnar and Alexander Magyarics’ six Ls puzzles and to combine them with the V-shaped tricube to make one of the 65 possible cubes and then put them in a box with only one opening. Of course, I started with my usual CASINO box, only to learn that this recipe doesn’t produce a sufficiently challenging puzzle, and neither does a FLOP box. Actually, I probably shouldn’t have been surprised. Given the filling of a cube-shaped box, the actual design task was to find the correct, single, continuous opening.

Despite the numerous specifications, FILLING V is a challenging puzzle whose solution still surprises me. But there will never be a FILLING I."

Having found several possible cubes, I quickly noticed that many could be discarded because of the requirement to place an L shape (or even more than one) in at the end as a last piece. This cut down the options considerably and then left me with the need to place 5 pieces in the box. Here lies the challenge for this puzzle. There seems to be plenty of space to place 5 pieces but with lots of wiggle room and all you can do is wiggle and I needed quite a bit more space than that. At this point it’s a request to think© and notice what the box does allow you to do. There is a really lovely Aha! moment here and suddenly the wiggle room becomes room to really do something. Burrtools told me that there are 65 possible ways to assemble the pieces into a 3x3x3 cube but I found something pleasing quite early on.

I placed my last piece in the box with a huge grin on my face! This is, on the face of it, a much simpler puzzle than the Flop series but I think is better for it. The best description is “elegant” - it’s almost as elegant as the classic Casino which won so many accolades.

It’s an essential purchase!

Flummox

Flummox by Benjamin Heidt
This beautiful and rather diminutive creation was designed by a new name on the scene, Benjamin Heidt. If this is a typical example of puzzles from him then I hope that Jakub and Jaroslav make more. It is a fabulous variant on the classic 6 piece burr with length of 6 voxels (pieces made from a vibrant Purpleheart). The addition of little additional pieces (made from Maple) added onto the sides of the burr sticks which interfere with the the usual movement of the pieces and make the solution much more interesting.

The solution level is: 13.4.2.3 which is just right for all but the most masochistic of burr solvers and is delightful to explore. From the start position there are 4 or 5 possible moves and then further exploration after some of them. This took me about an hour to solve using my usual to and fro method which also meant that I could reassemble it from memory. The really good solvers will disassemble it relatively quickly and then have a really nice challenge assembling from scratch.

Beautifully made pieces

Appletree

Appletree by Benjamin Heidt
Here we have another very interesting design by Benjamin Heidt. It is a beautifully burr made in the shape of an Apple tree complete with apples amongst the foliage. It has been stunningly created using American Walnut, Acacia with Padauk apples.

This takes a bit of fiddling and exploration in every direction to find the first piece to move and after this, if you’re anything like me, it’s followed by an “Oh my God!!!” moment as all of a sudden a whole LOT of pieces move in various directions. Slight panic ensued and I quickly decided to return to the beginning and discovered that it wouldn’t go - aaargh! It took a frantic few minutes to sort of scrunch it back together and breathe a sigh of relief. I had to gird myself before trying again. This is fun! For me it’s a puzzle version of a rollercoaster.

Having done that several times and worked out how it locked and unlocked, I proceeded to explore and quickly found that several pieces were removable. I kept them in a place where I could tell the position and orientation. After removing 4 or 5 the trunk fell off and it sort of scrunched up again. I was lost! Despite this, the puzzle remained pretty stable even if everything was jiggly. I actually struggled to remove the remaining pieces, they did not just fall apart. Over the next 20 minutes I gradually disassembled it piece by piece and, oh boy, there are a lot of pieces.

Appletree pieces
After all of that, I had not even done the main challenge! This is not a stunningly designed sequential disassembly puzzle as I alluded to above…it is actually an assembly puzzle - the tree, as received, is in a "transport configuration" - the actual aim of the puzzle is to assemble the tree again but with 4 red apples on each side of the tree. There is no way that I was going to reassemble the transport solution without assistance let alone the main challenge and so I am off to Burrtools for a happy time sketching pieces out. Great fun!

Rattle Twist Duo

Rattle Twist Duo by Osanori Yamamoto
My friend's version
This beautiful interlocking puzzle designed by Osanori Yamamoto is made from Maple (pieces) with 2 different frames: one Jatoba and the other Zebrano. This one was so good that it was made for me by my greatly missed friend and mentor Tsy Hung Chein (aka Felix). Felix had one of the best eyes for a fabulous puzzle and if he took the time to make a copy and send it to me then you can be assured that there is something special about it. I had absolutely adored the copy sent to me - and I am delighted that many others will now get to experience a puzzle that looks simple but has significant challenge to it. 

Osanori-san’s documentation that he sent to Jakub said that the 2 interlocking pieces should be sent out locked on one frame with the aim being to remove them and place them on the other and then return it to the start position. Like many of his creations, rotations are both possible and required. For a puzzle with only 2 pieces to be fitted on a relatively simple frame, this should not be so difficult. Despite having done it before, it took me a good hour to disassemble one and assemble the other. 

Then going back the other way after a delay to allow forgetting was just as much of a challenge.

Parallel Burr Cube #2 

Parallel Burr Cube #2 by Osanori Yamamoto
Another challenge by Osanori-san, this consists of a Frame made from Bubinga and a set of 6 board burr pieces made from Limba. It is strikingly beautiful. Initially I thought that this was just a framed 6 board burr but it’s not quite this. The boards are held apart from each other by the frame making sure they interact loosely with each other being trapped by just the end-plates of each board. At the beginning there are several possible moves but the paths are mostly dead-ended after just 1 or 2 moves. This means no huge long fruitless pathways to explore. It requires a search for something that goes somewhere and for me, took quite a while to find the required move that opened up the puzzle for further exploration. The first piece can be removed quite quickly after just 6 moves which then allows you to peek inside and gain some more understanding of the interaction of the pieces. Having removed the first piece, it does not seem to get any simpler and the puzzle transforms into almost a disentanglement puzzle - it is like unravelling a knot inside a box whilst you can only see a small section of the knot at a time. It is at times frustrating, sometimes fiddly as the boards can catch on the edges as there is a little wiggle room, but is always an enjoyable exploration. The move count is not particularly high but it is still fun to explore and work out at each stage how to make room for the next piece to slide.

You can see how the pieces are locked in place
Having dismantled the puzzle over about an hour or more, I had kept the pieces in order of their removal and remembered which position they had come from. All with the aim of facilitating reassembly without resorting to Burrtools. I was feeling quite proud of myself as I inserted the first three and then for some reason the fourth one just couldn’t be inserted. What was I doing wrong? A careful look at the shapes of the pieces revealed that the second piece had been inserted upside down followed by the third correctly and this couldn’t leave room to insert the next. OK, having realised this, take it apart again…except I couldn’t dismantle it! Aargh! Minor panic ensues and I have to work out all over again how to undo the interior disentanglement puzzle I had created for myself. After a frantic 10 minutes, I had all the pieces and admonished myself for being an eeejit and not keeping track of piece orientation as well as order. After this it went back together nice and smoothly. This puzzle is wonderful - it looks great, is sort of a burr and disentanglement puzzle at the same time and, if you are good enough, it can be a really tough assembly puzzle as well.

MRI

MRI by Benjamin Heidt
This new rather quirky and very attractive puzzle design by Benjamin Heidt is a new type of puzzle for Pelikan and I am not certain how to categorise it. Apparently Benjamin is a technician who works on MRI machines in hospitals. He must be very used to working with magnets and there are several of them inside this puzzle. It looks just like an MRI scanner complete with a patient (he has hair and a nose!) on the scanning platform inside the magnet. The aim is to remove the patient from the scanner by unlocking the hidden interior mechanism. One thing Benjamin should know is that you must NEVER bring another ferrous metal object inside the Faraday cage walls of an MRI room because it will turn into a missile if released in the room (believe me, I have seen it with an old Molybdenum steel oxygen cylinder - it moves very fast and does a LOT of damage!) but here he has disobeyed all the rules. The puzzle has a magnetic ball bearing on the floor held by a magnet embedded inside it and obviously this magnetic bearing is used to somehow unlock the patient from the scanner and remove him. 

I do not know how many steps is required because I have so far not managed to do much more than make interesting clicking noises as I move the bearing over the surface. I am making things happen inside but so far I have made no progress with the release - my patient may well starve to death in the MRI! I may be reduced to having to take it to work and asking a kind radiographer to take an Xray of it for me.

This is certainly something interesting which we have never seen before from the Pelikan workshop. Well worth adding to your collection for the quirkiness and the considerable puzzling challenge.

Matchbox Playground

Matchbox Playground - an extension of Oskar's idea by Péter Gál
This rather large puzzle set must be one of the most beautiful puzzle sets that I have ever seen! It is simply stunning and an amazing scope of work by the designer and by the craftsmen. It is the result of an epic amount of work by the incredible puzzle designer, Péter Gál.

The box opens like a matchbox
There are puzzle sheets and an explainer inside
Cubic dissection version
I have quite a few burr sets and this one ranks up there alongside the very best of them and will take pride of place in my collection. It is not a burr set but a set of increasingly difficult assembly puzzles based on the wonderful and clever Oskar’s Matchboxes puzzle that has been produced by several craftsmen over the years as well as 3D printed. Oskar's original puzzle had 5 pieces and I found that one pretty challenging. Later the idea was extended by Alexander Kapkan with 6 pieces and again by Onno Hein with 6 pieces in a different configuration. Over more than a year Péter had performed an exhaustive computational analysis. A smaller version of this had been released in the IPP design competition in 2016. Péter's analysis was restricted to a 3x2x1 matchbox with the matches attached at the gridlines giving 14 possible match/matchbox pairs. This puzzle set is contained in a gorgeous box shaped and sliding open like a matchbox itself to reveal the full set of 14 possible pieces and an envelope with an explanation and puzzle challenges ranging from using just 4 pieces up to the maximum of 13. 

Just look at the presentation here - it is amazing!
There are effectively hundreds of challenges here as each one has multiple solutions to find. The individual boxes are stunningly made out of Maple, Wenge and Jatoba and the case made from Maple, Wenge and Oak.

This picture will be essential if I am going to put them back!
When I took a few out to admire them, I realised straight away that I would need a photo of how they were arranged in the box! If you do just tip them out then an additional challenge for you will be to pack them back in again - I was not brave enough to do that! The challenges are really fun to do and require considerable thought. The cards show just the required pieces and not the eventual shape that you need to use. This means that simple entry into Burrtools is not possible. I have managed the first couple of challenges and really look forward to spending real time with this set. This is absolutely fabulous! I have put 3 of my solutions to the first challenge behind a spoiler button - if you plan to buy the set then don't look at it:


Should you buy this set? Hell yes! It's stunningly gorgeous, a whole lot of puzzling challenges. I absolutely love puzzles that come with a booklet of challenges e.g. the Peanut puzzle, the cubic Mazeburr, Rhombic Mazeburr and Split Mazeburr and this new one from Pelikan is just amazing!
