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.

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.

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.

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.

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!
