Burrs With A Twist

Literally... With Twisting Movements In Them!

Trust Steve to produce something funny with an extra twist in it!
Boarin' Burr - the boars appear on every surface

First of all, I MUST give proper attribution to the origin of last weeks main puzzle. The wonderful version of the Diagonal Star puzzle that I wrote about last week should actually be named the Sequential Cube. It was designed by the amazingly talented George Bell as a variant of Lee Krasnow's very rare Sequential Star. Practice does improve things with this puzzle - I can now solve the Sequential Star version and the 9 move version quite easily. The 14 move seems to be more problematic for me but I keep trying. If you get a chance to play then go for it - it's very mind-bending.

I should also point out that we have a new blog in the puzzlesphere - Fraser, whose name I forgot last week, has started an unassuming little place on the internet where he asks the useful question: Can an idiot solve it? This looks really useful to me - I have been an idiot my whole life (I'm pretty old now) and am rubbish at puzzles. I will be using his advice to see whether I should bother trying to solve some of the puzzles I see on the internet. Go show him some love/views! 

Today, I am writing about a couple of puzzles that look like burrs and sort of work like burrs in that they are composed of interlocking sticks but there is something twisted inside both figuratively and literally.

The IPP provides all of us with a list of puzzles we want. I am lucky enough to be given a few of them every now and then. Everything that the TwoBrassMonkeys do should be added to your list of things you want because there is always something special about them. Here, I have Steve Nichol's exchange puzzle. He designed a burr with some extra challenge to it. The theme is both the boars that are often found zooming around Italian towns causing havoc (Steve, cause havoc??? Oh yes! everywhere he goes) and of course, the name refers to the fact that pieces rotate like bores. and effectively double lock the burr sticks. Steve likes interlocking puzzles but always seems to want to make something a bit more interesting than a standard version. He has created them from hexagonal sticks and round sticks to confuse you. He's made odd movements and multi-step sequential discovery burrs which won my puzzle of the year for 2024. There seems to be no end to the ways that Steve wants to play with your head. In this case he has a burr with boars that got bored and bored their way inside your burr:

If you push on a boar then it unscrews from the puzzle!

This is interesting and very ingenious. It is quite reminiscent of Oskar's screw burr but extra confusing! Obviously this cannot be entered into Burrtools so you will need to be careful. Luckily everything is sequential and you quickly can produce a bunch of very odd looking sticks. Make sure that you mix them all up so that you have no idea what came from where and what orientation they were in when you started. This was one of my mistakes initially. It did not occur to me that stick orientation would be that critical when I scrambled them and I really struggle to reassemble it the first time.

There's nothing boring about this puzzle!
I have absolutely no idea how he designed this

The multi-coloured sticks can be assembled into a six piece burr in lots of ways but the locking mechanism comes from the bores/boars. Take a look at the notches in the sticks and with a little care it is possible to put it back together again with only a little trial and error as sticks may need switching end over end.

Great fun, with a twist - just as we would expect from Steve. Thanks mate. I assume that this will be put up for sale at some point. Keep an eye out on the Two Brass Monkeys website.

SV Burr by Richard Williams (P91 puzzles)

This burr is a fascinating design by Richard Williams. The aim is to disassemble and reassemble the burr and, most importantly, in the process, understand why it has the name SV Burr - what is SV? I bought it at an MPP last September having watched lots of people struggle both with the disassembly but also get caught out by the reassembly. I made sure not to watch what they were doing and what they had found along the way. I took it home and began playing. Initially it has absolutely no moving parts and takes quite a bit of pushing and prodding to make your first move. Very quickly a tool is o=in your hands - not what you would usually think of as a tool - it's just a bolt. What can you do with a bolt in a burr?

There are a couple of holes in the puzzle where you can poke the bolt but no real clue as to whether this is having any effect. After poking and pushing and screwing and unscrewing I did find something and then movement happened. Yay! After that, nothing else was possible but I did have another hole. I "screwed" my courage to the sticking place and put the bolt in the hole and closed up the burr in the hope that I could now use gravity to pull or push something inside. Well, that was a stupid thing to do because now I couldn't move anything. After a day, I contacted Rich to see whether I was on the right track and apparently I had been very stupid! He had never even considered that anyone would be so stupid as to do that and advised me to try and undo what I had done. As always, never underestimate my stupidity! Eventually, I did manage to undo the mess that I had got myself into but it took a couple of days - phew! Then, of course, there was more stupidity! I tightened something to much and stripped some of the plastic off - this rendered my puzzle non-functional! Aargh! Yep, I'm an eejit!

At the next MPP, I had to give it back to Rich to fix. I eventually got it back at the last MPP and promised to be more careful with it this time. I started again determined not to prove myself too foolish. I did the first moves again and achieved my sliding burr moves. This time I did not lose a piece inside. I worked on various other possibilities and somehow managed to get more movement. I was screwing and unscrewing but not understanding why it changed things inside. Despite that, I managed to progress. At some point a new too dropped out and I had no idea where it came from. A little exploration revealed a hidden compartment which had been the hidey-hole. The new item was an odd looking tool but there was only one place it could go and in it went. In fact it went in and out several times causing some more screwing movements and another piece came off/out. Turning the puzzle over caused yet another tool to drop out and this time I had noted where from. After searching about there was only one place to try it and yes, more screwing about. Then the final piece was removable and the burr came fully apart:

A six piece burr?
Nope! A lot more than that.

After this it becomes clear what the SV stands for - I'm not going to give it away. You need to get your own copy of this and work it out for yourself. Thanks Rich!

So we have to burrs that have lots of twists in the tale and twists in the puzzling. Fabulous - I need to lie down now as I'm really quite dizzy.

A Good End To A Bad Week! Sort Of...

MPP puzzle haul

It has been a rather bad week. Some very very big very looong operations which were not expected to be so big or so long which turned a couple of normal days into some very stressful big days. There is an old adage in anaesthesia that "many a good anaesthetic is spoiled by a surgeon having a fuck up" and this was very much the case. Nothing incompetent I hasten to add but just unexpected, unprepared for occurrences on the surgical side made my life very tough. It did mean that I had managed no puzzling at all during the week and was hoping that I might manage something to write about at or after the MPP. I was really quite pleased when the weekend hit and it was one of those days to get in the car and drive a couple of hours to Birmingham for an MPP with an unrecognisable roman numeral on it. I always buy a gigantic pile of car sweeties (I always lie to Mrs S about exactly how many bags I consume) to keep me going during the journey there and back - the constant dipping into the bag(s) prevents a knackered sleep deprived puzzler from dozing off in the car. It also has the added advantage of leaving me completely wired with a sugar high for a day of puzzling and banter. You will find out later when Allard writes his review of the day that I was particularly wired at one point and the tongue was loose! 😱🤣

One piece "unpacking" puzzle - OPUP

OPUP starting position

After getting home on Saturday night I picked up a couple of toys to play with and my misery continued. I had watched several people play with Dan's exchange puzzle the One Piece Unpacking Puzzle. A play on the original One Piece Packing Puzzle from the late Eric Fuller. Dan was kind enough to give me a copy and said that it really wasn't that difficult. Bastard!

I was hoping that I would have more luck with it than Eric's original which took me the best part of a year to solve!

Only took me a year! With some help

I duly removed the wire loop and took out the cube - There are 24 possible ways to insert the cube into the box and Sod's law actually made me get it right on the 20th try! This didn't bode well!

Now unpack the bloody thing!

AT the MPP, quite a few people played with it and I caught cries of delight at their success. I was very careful not to watch what they had done and this was the first one that I picked up when I got home. How hard could it be? Oh you stupid boy!

I have now spent about 4 hours playing with it and found a tool which has no apparent use and that is it. I have used a light source and a magnifier and found nothing useful at all. I'd like to put it down to fatigue from the week but nope, it's purely that I am rubbish at puzzles! There is only one cube to remove from a box! The temptation is to try and stuff a shim down the edge but it would need to be very thin and that would be cheating. Dan may be helping me out sometime! 😭

Next up when I got too frustrated with the OPUP, I had to play with something else to prevent me throwing it across the room. I picked up the Hamstersaurus puzzle which, with that name can only have come from big Steve!

Just from the name, you know who's puzzle it is

It was a burr and I really thought it was a variant on the tetrahedral burr that I had had fun with from my last MPP. A standard 6 piece burr but with extensions on it which interfered with movement and really messes with my feeble brain:

It's rather beautiful and has very sharp points!

It took me about 10 minutes of pushing and pulling everything in every direction to find the first move. The new shape still messes with your head. I then got a bit of a shock! It's not a standard 6 piece burr. As soon as the first slide has happened, it becomes clear that Burrtools is not going to help me later. There are diagonal faces inside! Oh Lord! Is this like the NOS burrs from Gregory Benedetti? Was I going to have 6 bright colourful pieces in a pile forever more? The rest of the disassembly took only a few minutes and I carefully took photos of the pieces as they came out. I then scrambled it to take my photos and then give me the reassembly challenge:

Hell! That is going to be a challenge to reassemble!

Luckily, Steve has designed this in such a way that the reassembly is possible using logic and a knowledge of burrs (a little bit of my too and fro memory probably also helped) - this one is possible for a simpleton like me in an hour or so. Phew! Some success at last!

Now I need to start shaking the OPUP vigorously to try and dislodge the cube! 😱🤣

A Lone Star Burr Is Not Really a Burr

But It's A Really Fun Puzzle!

2 of the 3 deliveries in one week
Whack! Ouch!

Yes, it's been yet another 6 day working week for me and as a result not much time or energy for puzzling. Luckily I only have one more Saturday to work and then I can have a little rest. Whilst puzzling takes a good bit of time and energy, collecting only takes a message or a click of a button and is much easier! This week Mrs S found out how much easier as she ended up answering the door to various delivery men 3 times. Between her purchases and mine, we are now on first name terms with all our postmen/women as well as the Evri and UPS drivers. I had been lusting after the Minima set by Tye Stahly and Frederic Boucher after Allard's amazing review and when another set was made, some PayPal was offered and Richard from UPS came to the door. I couldn't resist adding a 5 piece jigsaw from Haym Hirsch into the box. Then yesterday whilst at work Mrs S was forced yet again to open the door and receive a delivery of Mr Strijbos' last 2 exchange puzzles. Do you think I should tell her about the big box that Ali brought back from IPP for me? I think I should pick it up direct at an MPP rather than risk her wrath by making her bring in another package! 😱😱😱

The next day was the delivery from Big Steve and Ali with their IPP exchange puzzles inside and of course, the masterpiece collaboration with Shane Hales, the Who Dares Wins lock/box aka Haleslock 6. You just cannot beat the Two Brass Monkeys for puzzling beauty.

I had to get something solved for today and after quickly putting the key into the Who Dares Wins lock and finding that it doesn't turn at all in any position, I had to try something that I might actually manage to solve this week. I suspect that the Haleslock 6 might take me a year or two to complete and certainly not in a few days. I picked up the one puzzle that the boys had described as "not super difficult" and hoped for the best... Steve's Lone Star Burr (not a burr)

Lone Star Burr

It really is quite stunning. A lovely big dodecahedron with the Texas flag on each side which will come apart into a 5 piece interlocking challenge. I had not really paid attention to the description saying 5 pieces on the site and just placed the order as soon as I knew they were on sale. This lack of attention led to a a bit of an issue with the solve for me.

On Thursday evening after work, I sat down and pushed and pulled at various bits to see what I could make happen - after a few minutes I found a section had moved a mm or so and I actually began to wonder whether it actually was a burr but that initial slide stopped and I had to squish it all back together again. After a few tries, I managed to grip it right and my squish and pull ended up with it pulling apart into two halves. This put an end to my delusions of burr-ness. My first erroneous thought was that this was a wonderful variant of the Diagonal star puzzle and that each half would then split into 3 more pieces. Before continuing with the disassembly I checked out the way the odd shaped halves slid together and marvelled at the design chops that managed to make this sort of dissection possible. Steve is yet another of those geniuses to join Derek!

I put the two halves down on the sleeping cat on my lap and the slid off and fell apart. Oh dear! It's not a variant of the diagonal star! This was "just" a dissection of a dodecahedron and was not going to be as easy as they said on the website:

Five very complex pieces

I spent the rest of Thursday evening swearing at Steve under my breath as I systematically failed to reassemble the bloody thing! Unlike the Diagonal star, this can only be reassembled in one way with the correct set of pieces in each half. Of course, I had absolutely no recollection of what had come from where and so tried to be systematic. This is not that easy with such complex pieces as it's quite tough to make any of them fit together. That evening, I did manage to successfully create two good looking halves:

Two halves - bloody useless to me!

It looked so good! I lined the halves up and tried to push together. The gaps all matched perfectly but there was no way that was going to happen for me. Time to annoy Mrs S by swearing like a navvy and starting again. I worked on it on Friday after work as well and again failed. "Not super difficult", my arse! It actually took me a third session of play after work on Saturday before it finally went back together. The way it slides together is really quite pleasing as everything just lines up beautifully and what looks like it might catch and obstruct just glides past. 

I really need to try something easier and give my very simple bwain a bit of a rest! Maybe a 5 piece jig5aw might be easier? Knowing Haym, I very much doubt it!

I think I will put the key in this one more time and see whether it turns this time - the Einsteinian approach to puzzling!

I will dare but I am unlikely to win!
