Spread the Love. The Puzzle Love that is.

This summer I had fun doing twisty puzzles with the Czech kiddos. Some of the puzzles even got to leave with them and travel around the world. The yellow Bump Cube and the Carbon Fiber 3x3x3 went with Annie. The Redi Cube and a Six Spot Cube went with Alex. A 2x2 Cube and the Rediminx went with David. Annie and Alex each mastered the ones they took along with them. David is great at the 2x2 using the 3-step method Solution Guide we made together. And we played a little with the Rediminx and I'm confident that he will be able to figure it out. Perhaps we can do some puzzling together in Google Meet.

Shape Mods

Mirror Blocks by color

Mirror Blocks by shape

Ghost Cube

Red Twist

Fluctuation Angle Cube

Windmill Cube

Pyramorphix

Master Pyramorphix

Most of these are relatively simple to solve. The one that gave me fits this time was the Ghost Cube. I took photos before scrambling it and used them when solving. It was still very difficult for me.

2 Weeks???

Has it been that long since I did an Eyes Closed Solve on my first try? Yesterday I had another fail on the first try. This morning I got it right.

I'm thinking about going back to using only the F Perm on the corners and M2 as much as possible on the edges. But on this last solve look how much jumping back and forth there was on the edges. Maybe I should go back to using only the F Perm for awhile until I am good at it again. I dunno.

Well, I tried another solve and again messed up on the first try. On the second try I just did the corners then checked, and checked several times through the edges. No messups, but lots of looking at it to make sure I hadn't messed up. Sheesh.

I have put the Tangram Cube away. And until I get confirmation that Josiah still wants to learn the Mirror Blocks, I am not solving it like I was every day. I am determined to get back to being able to solve the cube Eyes Closed on the first try consistently.

Plus I want to start learning OLL for the 2x2x2.

It is a little later in the day. I finally solved one first try start to finish eyes closed! It was less to remember and twist though as three of the top corners only needed to be twisted. Here is the scramble:

Practice Practice Practice

Just did an eyes closed solve. I got confused the first time through and forgot at least one of the steps. It was a mess when I opened my eyes. Tried again, writing it out this time in the spreadsheet. Well, I just wrote the letters, even though I had sentences for part of it. During the solve my mind wandered some and I thought maybe I had skipped something but when I opened my eyes it was all solved. Phew.

The Tangram Cube is still fun and has my interest. I try to solve it once a day at least.

The Mirror Blocks Cube lessons with Josiah started last Monday. We got through the intro and the first step in solving it. I should solve it at least once a day too. I got some stickers for mine and am going to get a new one and more stickers. For now my old one is naked so I don't solve it by color, just by shape. That's OK, since that is where I need the most practice anyway.

I also gave the Lidbeck family a bunch of my puzzles. Skewb, Square-1, Super Square-1, Snakes, Magic, Pyraminx, the Tower thingy with all the shades of different colors of balls, and maybe more.

Rubik's Cube Books

I got my first Rubik's Cube in the early nineteen eighties. The only way I could solve it was to take it apart and put it back together solved. Until, that is, I got some little books that explained sequences of moves that could be used to put pieces where you want them without messing up what was already in place.

The Simple Solution To Rubik's Cube
by James G. Nourse
Notes on Rubik's Magic Cube
by David Singmaster
Solve That Crazy, Mixed-up Cube Puzzle
by Don Frederick.

I think I put together my own strategy using bits and pieces gleaned from all three books. Eventually I lost interest and forgot how to complete the cube, forgot I had those books, and lost track of the cubes.

Mark Jeays' Working Corner Method

http://jeays.net/rubiks.htm

In 2007 my interest in Rubik's Cube was rekindled when I watched the movie The Pursuit of Happyness. Marae found my 1980s cube for me and I tried to solve it. Huh-uh. I could do part of it, but not the last layer. Looking online I found various tutorials. Mark Jeays included YouTube videos with his Solution 2. This method worked for me and although I no longer use it in its entirety, nor could I, as I have forgotten the yellow edges sequences, I still find the basic working corner technique helpful, and use a slightly modified version of his corner twisting technique at times.

In the summer of 2014 we packed 30 or so puzzles and flew to visit Raymond and Fam in the Czech Republic. Breann, who had learned this method and no other, made some comment about bubururu or something like that, and it piqued my curiosity. What were those algorithms, and how similar are they to the EPS technique I use now when using a working corner? So I looked them up. Actually, the three algorithms were for dealing with the two last edges solved, which either needed to be swapped, or flipped, or swapped and flipped. The swapper is very similar to the one I have learned and used since, but I actually like it better in one sense, with a slight modification.

To swap UR and FR without flipping:

U' R U' R' U' R U' R' U'

To swap and flip UR and FR:

F' U' F U' F' U' F U2

To flip UR and FR:

F' U F U' R U' R' U

Will I actually learn and use these? Probably not. But I like them. :)

There is a slightly different implementation of the Working Corner Method. Arnaud van Galen calls it the Keyhole Method. I like his demonstration better than the one I originally learned. It just dawned on me why he is able to get away with doing it the way he does. He goes ahead and finishes the F2L before going to the last layer, unlike the way Jeays uses the working corner (keyhole) to also get the last layer. Since I no longer use the working corner to get the last layer, I should implement Arnaud's technique.

Jasmine's Scalable Method

http://peter.stillhq.com/jasmine/rubikscubesolution.html

This was the next method I learned. For awhile the idea of speed cubing appealed to me. This promised to be a good beginner's method for those that wanted to go on to faster method's later. Now that I know what I know, I wouldn't recommend this method if your goal is to be able to consistently solve the cube in less than 30 seconds. Rubik's Speedsolver Champion Leyan Lo presents a beginner's method that I like the looks of although I've never learned it. I have recently watched Arnaud van Galen's complete beginner's method video series and recommend them. Gilles Roux presents a beginners' method that is very close to one of my favorite ways of solving the cube. The simplicity and comprehensibility make this method a good place to start if you want to understand the Rubik's Cube. Also, if you are interested in speedcubing you should check out this YouTube video.

After trying for months to get under a minute with both Jasmine's Method and the Corner's First Method—and failing, I finally decided to quit trying and just enjoy cubing at a nice slow pace.

Don't get me wrong. Jasmine's Method has its merits. The sequences for orienting the last layer edges and corners, and permuting the last layer edges are still in my arsenal of useful algorithms.

Adam Cheyer's Corners First Method

Philip Marshall's Ultimate Solution

http://helm.lu/cube/MarshallPhilipp/
After learning to solve the cube corners first, what is next? An Edges First Method! This was a very difficult tutorial to follow, but once I got it, it was my favorite way to solve the cube for awhile. It uses only a few algorithms, and when you are finished solving the cube you feel like you've solved the puzzle, not just used memorized sequences to unscramble it.

Gilles Roux presents a beginners' method that could be used to solve the cube edges first. The simplicity and comprehensibility make this method a good place to start if you want to understand the Rubik's Cube. His technique is much easier to follow than Marshall's.
