# 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

Mefferts.com 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. 😀

## Confused

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.

## Clear

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.

# Sudoku Cube Page Added

Here.

I also added a page for the Floppy Cube that isn’t a cube. I did the Floppy Cube page in Excel.

# 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.

Mefferts.com 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.
