Sometimes Burrtools Is A Godsend...

And Often Not!

P3C by Yasuhiro Hashimoto (produced by Mine)
Every 6 months or so, Mine offers up a bunch of puzzles that his Japanese friends design (many of them appeared in the IPP design competition). The P3C arrived and I set to work on it shortly after it arrived. Needless to say, I failed! Again and again and again! It got to the point that I put it in my work bag and would get it out every few weeks to try and yes, you guessed it, fail again! 

There's another one that shares that fate - the Turning Quarter Hole has been in my bag for 5 years and still not been solved! OMG! I received it in March 2022 and still not solved it. Maybe I need to give up this puzzling hobby?

Interestingly, these two puzzles share the same 6 tetromino pieces and same aim of packing them in a box that measure 24 voxels in volume but have different dimensions (the P3C has a box that is 2x3x4 and the  Turning Quarter Hole box measures 4x4x2 with all 4 corners blocked by diagonal walls. Obviously the entry holes are different and the latter puzzle has a top lid that is captive but can rotate freely. 

These two have accompanied for such a long time that I eventually got desperate with one of them and decided to let Burrtools do a comprehensive analysis for me. I was pretty certain that it would not be able to solve it for me. The box has a nice 2x2 hole in the top and there are two single voxel holes in the bottom. I did wonder whether the solution would be linear with pieces needing to drop through the holes to allow others to pass over the top. But... after nearly 2 years of trying I was fairly certain that the holes in the bottom were just finger holes to allow manipulation and that some kind of rotation might be needed. 

I duly entered the puzzle entirely into that wonderful programme by Andreas and, as expected, no solution popped out. It did give me all the possible ways that the 6 tetrominoes could be assembled in the box. "All" that was needed was to try them all out systematically and work out which could be disassembled a reasonable amount through the hole in the top until there was room for other pieces to achieve any required rotations. BT found that there were 28 possible assembles and I started at number one. It didn't take much to work out that all but 3 of them were absolutely impossible as solutions. After this, I tried to be systematic on them and skipped past the solution for several hours. It was right in front of me but I couldn't see it! Those holes are not just finger holes - once you realise that there are a whole lot more possible moves to think about. I had my Aha! moment and finally one of Mine's creations can be put away. Yes, Burrtools to the rescue yet again.

I am not going to show the final packed solution because that is not allowed with these puzzles from Mine. I don't think he has any left but I am sure that you could find the shapes and print your own if you were allowed a 3D printer in your house. Unlike me who daren't even think about it.

I still have the Turning Quarter Hole puzzle accompanying me everywhere and I don't think that BT will help. 

Actually, whilst I am focussing on Mine's puzzles that are always with me there is an even "simpler" design of Koichi Miura's produced by Mine, the Chiral 2&2 which has also completely stumped me because rotations are going to be needed and BT won't help me:

Chiral 2&2 by Koichi Miura
This one has just 4 tetrominoes to be placed in a 3x3x2 box - yes, there are 4 spare voxels free inside so it should be easy peasy - but not for me. I have had this one and gotten absolutely nowhere. Sigh!

Finally, Tye Stahly sent me another Minima puzzle - this one, designed by Kyle Waszak and Ryan Sinatra, shares the 2x2x3 cavity of the usual Miinima box but has a slide on lid.  As soon as I tipped the pieces out, something didn't look right. I had to put my maths head on and calculate that 2x2x3 equals 12 voxels. Then I counted on the digits of two hands and then a foot (having taken my shoes and socks off) there were 12⅓ voxels on the pieces to be packed. Huh! Well, that's odd. Is there a hidden dimension or a portal to somewhere else? I quickly made two vital discoveries but they didn't seem to help with this puzzles at all. BT definitely wasn't going to help with this one! 

Damn you Tye! Is this another one that will be traveling with me for years to come? Sob!

If you want to try and succeed where I failed then it is still available from NothingYetDesigns.

Frederic, Tye And Josh Try To Kill Me...

But They Do It With a Jolly Good Puzzle

Res Q version 2
Happy New Year fellow puzzle sufferers! I hope that this will be a happy healthy one with lots of fabulous challenges ahead.

A few years ago I had missed out on the late Eric Fuller's collaboration with the amazing Frederic Boucher producing the beautiful Res Q sequential discovery puzzle. A very trusting friend, Andrew Coles lent me his copy and it took me months and months to solve it. In the meantime Frederic himself made me a special edition which he called Visitor Q+ with an extra step just for me. I loved it (even if it took me an unbelievable amount of time to solve. 

Needless to say, I recalled playing with the puzzles but had absolutely no recollection of the solve process. I didn't even remember the first step! Mrs S would view this as a reason to only own 4 or 5 puzzles and keep solving them in rotation with no memory of when I did it the previous time. Tye Stahly of NothingYetDesigns had collaborated with Joshua Clouser to reproduce and expand the Res Q puzzle. They offered a pre-order and having missed out on the original, I pitched in without even thinking about it. The puzzle arrived a few weeks ago and I had to put it aside whilst I worked every weekend for two months! In fact, I am working again this weekend - no rest for the wicked! I finally decided to start work on it on New Years Day! I had a day off and "she who must be feared" did not have a list of chores for me to carry out. I had a whole day to work on it.

Comprehensive instructions but no clues
The alien is trapped in the vortex 

The puzzle has been beautifully 3D printed with a heavy infill and is quite weighty as a result. 

It comes with a page of instructions. The most important part at the beginning is to retrieve the spaceship whilst avoiding rotations of the vortex parts and also the ship itself. 

That sounds great but in the start position nothing can move at all! Great! I was stumped immediately. Sigh, not terribly bright. 

There is a clue - the Guitar pick on the top. This had not been on any of the original puzzles and I had to ask Tye whether the pick was removable as it was held on the green lump quite hard. Having gotten permission to use a bit of force to retrieve the pick, I had to work out what to do with it. 

You would think that I might have some recollection of one or two of the moves from my previous experience but nope, I am completely blank! Just ask Mrs S about what is in my head...I am a proper bloke and my head is completely empty almost all the time. I have quite severe insomnia and the ladies I work with always ask whether I lie awake thinking of "stuff" when I wake in the middle of the night. They are literally amazed to hear that when I am conscious, my head is completely devoid of anything resembling thought! As a result of this emptiness, I had no idea what to do with my immovable puzzle. I had a guitar pick and a few places to try and slide it so I guess it's time to see what happens when I do.

I found a few places it would go and after a few minutes had my first Aha! moment. I found something new and the possibility to retrieve a new item. Nowhere for it to be used yet but progress was being made. At this point the vortex was mobile, really, REALLY mobile! This thing anted to rotate but care was needed to not allow rotations. The spaceship becomes visible and can be moved around with the vortex spinning around it. The spaceship cannot be removed easily as the holes are all too small or require an impossible rotation to achieve. The exit is pretty obvious but needs a lot of moves to be reached.

At some point, I must have inadvertently rotated a piece and then got stuck. The rocket would not advance or return and I couldn't work out how to undo the rotation. Aargh! Chest pain number 1 took a good while to settle as I worked feverishly to return to the start. After about an hour of swearing and clutching my chest, I was back at the beginning and determined not to do that again! After a bit of a breather I started again with better concentration and control. It only took me an hour or 3 to retrieve the spaceship.

Colourful spaceship
The curved top of the rocket was part of the reason I struggled to control rotations. IT almost insists on turning sideways in the vortex. I was hopeful that the tool I had retrieved earlier could be used on the rocket. The tool has a very tiny thread on it and there seems to be a hole for it on the side of the rocket. I must have spent a good 30-45 minutes trying to get it to do something with no success. The trouble with being a man of a certain age is that you cannot see small things very easily. Using the magnifier on the phone proved to be a dexterity issue as I didn't have enough hands and Mrs S was not going to assist me in my madness. eventually I got a bright light, my phone on a tripod with magnifier activated and still failed to get anything to happen. At this point I had to conclude that I was attempting the wrong step with the wrong tool in the wrong direction and using a non-functional bwain! sigh. Back to the drawing board aka the vortex. 

Time to fiddle with the vortex and peer inside. Another Aha! moment occurred. I had seen something that might be useful. Time to manipulate the vortex and get to use my tool. Erm! That was the theory. Nothing would allow the vortex to reach the correct state to allow the next step. I had to contact Tye at some point to ask about rotations. he said they were required but could not remember which ones - that is helpful! At least I had permission to spin stuff but I recalled the earlier chest pain/heart attack caused by spinning a piece and not being able to undo it. I decided to take notes on what I had done in which direction.

Suddenly, I had a specific goal and the ability to move things however I wanted. It took a while but I was able to retrieve the first of the antenna rods to release another tool and then using this, the second antenna rod. I now had another tool. From here on it was a matter of gradually releasing tools from various parts of the vortex. It needed the vortex to be manipulated appropriately. Almost all of the tools are magnetic and snap together with a satisfying but rather alarming click. At one point, I had inserted one tool into a hole where it stuck to the next and then wouldn't come out. Time for my third episode of chest tightness (no radiation to arm or jaw luckily) and some more thought. That was painful too.

I was able to dislodge the magnet and the next tool by slapping the puzzle into my palm. It didn't feel right so, again, I asked Tye and he more or less told me off by asking whether Eric would ever implement something like that? Of course, the answer to that would be a firm no and, suitably chastised, I returned the pieces from whence they had been released and had another little think©. At this point point I had quite a lot of pieces, most of which were magnetic and a reasonable amount of space in the vortex to manipulate them. More pieces came out until I had all of them with the exception of releasing the alien and finding my puzzle number. 

I knew where it was, I could achieve it using an illegal move and I knew how to achieve it the "correct" way but I could not get my external magnet close enough to achieve what was required. I spent about 3-4 hours trying every rotation of the vortex pieces I could find with no progress. Nothing I could find would allow the vortex to get to a position that was useful. New Years Day was over with a headache and chest pain not caused by booze. I was having a "fun" time.......I think!

The following evening after work I got back to it - desperation was setting in as I had nothing else for the blog and I am working on Sunday. I HAD to solve it on Friday or Saturday. I had learned a lot with all the manipulations I had carried out and luckily had kept good notes of what I had moved. At this point I thought "in the box" and used both light source and fingers to investigate. 

OMG! That is really sneaky - why did I have no recollection of it?

I now knew what was required but needed to make a LOT of room to achieve it. Again, this sequence nearly gave me a heart attack as I could only ever get two pieces of the vortex into position at any time and each time I tried to backtrack, I would get stuck. After another few hours, I finally worked it out, manipulated the vortex in 4 dimensions and was able to use a combination of multiple tools at once to rescue the alien and find my number. OMG what a relief.

Two antenna rods, silver fuel disk, gold rector orb and radioactive fuel
My number is my age - 43 🤣
Now, having admired what I had, I could take my photos. There were a lot of pieces and I actually couldn't remember where they all had come from or where they all went. I also only had a vague idea how to undo all my vortex moves to return to the beginning. Luckily the reset is only a small subset of the moves to solve it. Most pieces can be returned to their places without complex manipulations once you have worked out where they should be. The hardest part is undoing the vortex moves. I was slightly horrified to realise that my notes were quite good for repeating the solution at a future date but absolutely awful in helping undo the moves to return to the beginning. I had to work it all out all over again in reverse.

If you cannot work out how to reset the vortex then Josh has designed this with an easy cheat. There are two very fine hex screws on the top which allow the memory challenged puzzler to unscrew the lid and reset from above:

Two screws make an easy reset
Needless to say, I am a sucker for punishment and have started to enjoy the chest pain so I worked on solving the puzzle in reverse. It took another ½ hour but I was able to startle Mrs S and the kitties with my shout of final completion. I did prove to myself that my notes worked for a forward solve as I repeated it again straight away. I took a photo of all the pieces which is not an easy thing to do as the strong magnets all want to snap together. 

It is a tiny bit of a spoiler which I have hidden behind a button - you don't have to look at unless you really want to. 



OMG! It is soooooo good! My first puzzle of 2026 is straight in as a candidate for my top ten(ish) of 2026. Unbelievable! It's not wood but it has been beautiful made and doesn't feel plastic/flimsy in any way. I hope the year continues like this. Don't tell Mrs S but there might be a few puzzles on order already.

If you get the chance to play with, or even better, buy this puzzle then don't hesitate. This is probably an essential purchase for any serious collector or puzzler. Thank you Frederic, Josh and Tye for a great start to the year even if it did cause 3 small myocardial infarctions!
