I've written many times on this blog that I solved the Rubiks Cube in the 5th or 6th grade. My brother showed me a move, when applied, did not affect the opposite side. And since then I like to play with the cube to help me relax.
While in Germany last December, my wife bought me another Rubiks Cube, except this one has 4 x 4 pieces instead of 3 x 3. So I've been tinkering with it from time to time. The other day I was able to get 3 of the 6 sides to match. Then 4. And last night I had all but 2 pieces in the correct position. In trying to solve it, I messed it up completely. And had to work at getting it back to its 4 sided state.
The patterns are similar to the 3 x 3 cube, except not exactly. There are some new moves required and I'm still learning them. Except some of the moves are the same, and I got it to a point that I remembered from the other cube. So I twisted and turned and when I aligned the colors, holy smokes, all 6 sides were now in the correct position. I solved the 4 x 4 sided Rubik's cube last night. Yay.
There's also a 2 x 2 cube which I solved while working for the County in the late 2000. All have similar patterns but some have different patterns.
I like to work with the cube. Solve problems. Get into the zone, tune out and focus. Kind of like programming.
And there you have it~!
