Introduction to the Pages Page Added

I am working on a page that tells a little bit about each of the other puzzle pages. Since I have not finished posting pages on all the puzzles, this intro page is a work in progress. I haven’t even finished telling about all the pages I have so far.

I also switched from the template iNove to Silver is the New Black today. And have started grouping my pages together rather than listing them all separately.

Pyramorphinx Page Added

This puzzle from Mefferts doesn’t turn very smoothly, but when I can deal with that, I enjoy playing with it. It is a triangular pyramid—tetrahedron—that can morph into several other shapes. It is also fun to put patterns on it.

I’ve included photos and a video on the Pyramorphinx page.

So Clever, Yet So Confused

Clever has recently come out with a new stock of old puzzles, one of which is the Skewb Ultimate, which I do not have. There are several skewb-like puzzles out there. I have a Skewb and a Jing’s Pyraminx. With the Skewb there are 6 square pieces of a single color each. That means orientation doesn’t matter. On the Jing’s Pyraminx there are 4 triangular pieces of a single color each. Again orientation doesn’t matter. But with the Skewb Ultimate some pieces have 3 colors and some have 4, so orientation matters for every piece. That makes the Skewb Ultimate the most challenging of the Skewb family. A couple days ago I was participating in a forum post about the Jing’s Pyraminx, and an idea surfaced. If I would strategically add stickers to some of the pieces of my Jing’s Pyraminx, I could make it so orientation matters on every piece. That way I can have the challenge of the Ultimate without having to buy it. 😀


So why the confusion? In looking for a way to twist the centers of the Jing’s Pyraminx without scrambling edges I dug out the notes I had made while experimenting with the Skewb. I found a sequence that I think will work. But when executing it, I noticed that part of it involves doing The Move. I hadn’t recognized it as such before, because of the way I hold the puzzle and twist it. It just doesn’t seem very The Move-like.

Then comes the issue of notation. In one puzzle I call The Move R↑ L↑ R↓ L↓, and in another I call it R↓ L↓ R↑ L↑. And in my notes I use numbers that stand for the corners instead of R and L and have a confusing little arc to indicate clockwiseness.


Got it. Worked through the notation and came up with a solution. It looks complicated, but after doing it a few times it seems to flow rather smoothly. I’ve edited my Jing’s Pyraminx page.

Virtual Magic Polyhedra

Find them here.

Yesterday I solved a Pyraminx Crystal for the first time. It will probably be the last time too. It wasn’t a hold-it-in-my-hands puzzle. It was a virtual one. But I got to see what it was like. Pyraminx and Megaminx strategies were required. I used The Move a lot to 3-cycle edges. is selling Pyraminx Crystals right now for $42, but the virtual version is free. 😀

2×3×3 Rectangular Prism Page Added

The 2×3×3 is interesting because if you hold it so white or yellow is up then the sides can not turn 90˚ like they can with a normal Rubik’s Cube. Only 180˚ turns work.

If you know how to solve the cube corners first, then it is easy to use that method to solve the corners of the 2×3×3, but the edges are probably easier to 3-cycle home than trying to apply the Corners First edge strategy.

There is also a simple corner 3-cycle, so if you want to solve the edges first, then cycle the corners home, that works too. Or if you want to use a block building strategy, that can work. Sometimes with these two strategies, though, you end up with 2 swapped corners. It isn’t as easy to swap two corners as it is two edges, but it can be done using a simple algorithm and 3-cycles.
