Megaminx Page Added

The Megaminx looks very complex with its 12 faces and colors, yet is very simple. Like the Rubik’s Cube the centers are there as reference points, but they do not have to be oriented like they do on some of the shape modified puzzles like the Rhombic Dodecahedron, or like they do on picture cubes. The Megaminx is also simple like the Rubik’s Cube in-that it does not change shape as do the Octagonal Prism, the Fisher’s Cube, and the Master Pyramorphinx.

I like the QJ brand tiled Megaminx. If I ever get another Megaminx, it will probably be a Holey Megaminx.

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.

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.

Fisher’s Cube Page Added

Added a page for the Fisher’s Cube. It discusses briefly the three I have, and talks a lot about how to solve the 6-color variety. Maybe someday I’ll work out a strategy for solving the single-color ones. I think it would involve solving the middle layer centers first, as then I think every piece would automatically be in the right place. Some of them would just need to be flipped or twisted.

Skewb Page Added

Today was Skewb day!

Originally I experimented with the Skewb, writing down different sequences and what they accomplished. Then came the task of deciding which ones to use to solve it. I like simple. By that I mean few things to have to remember. So when it comes to getting the centers after all the corners are solved, I know there are other ways to go about it that may be quicker, or require fewer moves, but by using one familiar easy to remember 3-cycle, there is a better chance I will not forget it. So sometimes when solving the centers I only need to do the 3-cycle one time because it happens that 3 of the centers are already solved. But more often I need to do it multiple times, getting one or two centers at a time until there are three left that can be placed with one final 3-cycle.

Say after getting the corners, one center happens to be solved. Do a 3-cycle that solves the opposite center. Perhaps one other will be solved at the same time, in which case the other three can be done with one more 3-cycle. Otherwise, it will require two more times through the 3-cycle sequence.

Solve the Cube Edges First page

The Solve the Cube Edges First page explains one of my favorite ways to solve a 3x3x3 cube. It explains how to use the simple Up-Replace-Down technique to insert either bottom layer corners or middle layer edges. Then it explains how to use the Up-Replace-Down 3-Cycle to solve the last layer edges in one step and corners in another. Although it doesn’t use the term, The Move, it does show the sequence of twists to do The Move, as they can be used to flip two edges. I discovered The Move when figuring out the Skewb, and have since applied it to Jing’s Pyraminx, the Pyraminx, the Bandage Cube, and now even the 3x3x3.
