Topless Box – Eric Fuller

This puzzle box is quite amazing. The journey that it took me on from initial inspection to solution to understanding and examining the mechanics was nothing short of magical. I generally stay away from puzzle boxes – I spend enough time and money on other types that I have put a self-limitation on what I will buy – but when I saw this one offered by Eric, I just couldn’t resist.

A simple box flawlessly constructed and brilliantly devised.

The box itself is quite simple in appearance – and that greatly adds to the elegance of the experience. It’s a simple cube that has a lid on the top and a lid on the bottom. Both lids are secured by magnetic force and can be easily removed. However, removing them does not open the box, it just reveals a solid panel beneath. And… that’s about it. That’s all there is to work with.

The lid comes off, but the box doesn’t open.

With most puzzles that I have solved, there are pieces to utilize – you have to stuff a bunch of pieces into a box, or you have to take apart an existing cube, etc. The main difference here is that there is not much to work with. Thus, I had to really change my approach to solving this. I couldn’t just fiddle with pieces, I couldn’t really use trial and error, there was nothing to map out. It’s just a box with 2 lids. The process then, becomes more of a cerebral exercise. What exactly is going on here and what clues are there. The box itself feels empty. There are no rattling parts, nothing shifts inside, there really are no such obvious clues as to how to progress.

For many weeks, this puzzle sat on my shelf. I’d pick it up every once in a while and pop the lids off while shaking my head in defeat. After a few minutes, I’d return it to the shelf and wonder if I’d ever solve it.

Eventually, with enough prodding, I discovered how the box was put together. This was great, but at the same time I was even more confused. What was holding it together? How do I open it? The usual methods of spinning and banging didn’t yield any results nor did they feel like they should. It almost seemed that there was some magical force holding the box together. I was envisioning all sorts of crazy internal mechanisms holding it together, but nothing I imagined was even close. I tried all sorts of random things with the lids, but again, nothing yielded any results.

The box sat on the shelf for many more weeks and I moved on to other puzzles. Then, last night, I decided to spend some more time with it. Again, I ran through all of my previous failed ideas – and again they failed. I finally just say there and stared at the box and instead of trying random things, I used my brain to really think about things. This lead me to try something that then yielded a very small result and I knew I was on the right track. A few minutes later and I had the box open.

Amazing! The feeling of opening this was like none other! I was so excited, I was shaking and overcome with a flood of adrenaline. I had finally done it!

The inside of the box without revealing any mechanisms 🙂

Well, I knew what I had done, but I still wasn’t sure how it had worked, so I spent the next few minutes examining the insides, the mechanism and the trick to opening it. And I was further amazed – and impressed – and awed. In Neil Hutchinson’s Blog – Puzzling-Parts – He describes it as “elegant” – and I couldn’t agree more. It is so incredibly elegant. It’s so satisfying to finally understand how it works and to see the mechanism in action. I closed and opened the box many times and each subsequent time produced a huge smile, over and over.

Perhaps I should rethink my self-imposed ban on puzzle boxes. I know its a deep rabbit hole to venture down, but man, this thing was incredibly fun and supremely satisfactory to solve. Well done Eric. That was awesome!

MysTIC – Andrew Crowell

Ok, today, I have MysTIC – A very interesting 4×4 cube that I am anticipating will be difficult to solve. Here’s what Andrew Crowell says on his Etsy Page

MysTIC is a puzzle that a computer program I wrote designed. I built a copy, and then got frustrated because I couldn’t assemble it. I finally decided my program must have made a mistake, because the puzzle wouldn’t assemble… So I cheated and looked at the solution… And the puzzle does assemble, it just requires a few rotations, one of which I just couldn’t figure out, and a decent number of moves…

So let’s see if you are smarter than me, or more patient, or just plain lucky. Try to assemble this puzzle. If you fail I can give you the solution.

Well, that’s certainly a bit intimidating to read, but I’m gonna plow ahead and see what happens.

The puzzle comes partially assembled with just one piece left out. It is clear from looking at the cube and the missing piece that the leftover piece will indeed fit in the space provided, I just have to figure out how the heck to get it in there. I’ve got about an hour to kill, so lets see what happens.

This is how the puzzle arrived. Simple right? Just stick that piece in and call it a day.

Within the first few minutes of handling this puzzle, I’ve learned a few things. First, there are  only 5 pieces to this puzzle. And second, the first 4 are fairly trivial to put together. So clearly, the whole challenge to this puzzle is figuring out the sequence to get that final piece in. I suppose this is all clear from the description of the puzzle, but it’s even more clear when manipulating this puzzle.

Well, I am thoroughly defeated. In an hour’s time, I’ve managed to accomplish nothing other than to get myself extremely frustrated. The puzzle really seems quite impossible. I know it can be solved – unless this is a cruel trick, but I just can’t figure out how. I know there are rotations involved, but nothing I try seems to work.

Five beautiful pieces don’t make this any easier.

The above was written almost 9 months ago. I originally ordered this puzzle back in November of 2018 – and today – I’ve finally solved it. Talk about getting my money’s worth! This particular puzzle has sat on the shelf unsolved for all that time mocking me. Occasionally I’d pick it up and tinker with it, but I never got close to figuring it out. In the meantime, I’ve solved many other of Andrew’s TICs and it’s always been bothersome that this one remained unsolved.

Just a few days ago and I saw that Brian Menold was offering up MysTIC in his latest batch of puzzles. I briefly considered buying it, but since I already had a copy, I decided to pass. However, It revitalized my efforts to give it another go. I also had some new information to work with. Brian states in his description ” …this has a very challenging multiple piece rotation that is just amazing to me. This rotation can be made without any pressure or odd maneuvers. It must simply be done very precisely!”

Hmm interesting. So now I knew what to look for – a multiple piece rotation. Ok. Great. But still, how the heck does this thing work? I spent another hour or so working on the puzzle trying different procedures and configurations. I tried putting it together with just 4 of the 5 pieces. But I always came back to the same roadblock. There was a particular piece that I just couldn’t get to the other side of another piece.

Somewhere along the way, I arrived at this configuration. I love how these TIC puzzles can become so convoluted.

Frustrated, I put the puzzle down again for the day. This thing was really giving me a hard time. And then, tonight, I had my breakthrough. I’m still not entirely sure how it happened. I felt like the puzzle was falling apart on me, but then I noticed that the troublesome section was now in the correct position! A few manipulations of another tiny piece and I finally had this one together. Wow! I think I’d have to rank this one as the most difficult of the TICs that I’ve completed.

The completed puzzle! Brilliant!

Taking the puzzle back apart reveals the amazing movements required. I’m not sure how I stumbled upon the solution, but I agree with Brian that it is truly an amazing move – one of the coolest of all the TIC rotations I’ve seen. Now I know why it took me 9 months to solve! It’s that hard! I don’t want to give any hints, but suffice is to say that it really is quite remarkable.

Overall, one of the best of Andrew’s TICs that I’ve completed. It’s right up there with LunaTIC in difficulty and it provides a fantastic sense of accomplishment. Bravo!
