Rubik's cubes are less complected than you might think.

Image result for gan 356 xsThere are many misconceptions about the Rubik's cube and how it is solved. A lot of people think that you need to be some kind of all-knowing genius to solve one, but really it is kind of simple when you think about it. It is more memorization and recognizing when to do certain things than math and god-like powers. Yes, most people can't pick one up and solve it in 5 seconds, but I think that if you put enough time into it, you can solve it.

People also think that the world of cubing is made of just 3x3 solvers, but there is everything from 2x2 to 17x17 and even some less traditional ones like the pyriminx and the sweb.

The main concept of the 3x3 is algorithms (a series of moves symbolized by letters). The hard part is memorizing this series of moves and learning when to use them. Some people think you solve it side by side, but in reality, you do it in layers. The most popular method is called Freidrich's method, better known as CFOP. CFOP stands for Cross, F two layers, Orienting the last layer, and Permuting the last layer. The cross means that you make a cross, usually the white side, but what I see many people do is put any random edge piece in any place to make a cross. The problem with doing that is there is no way to solve the cube after you do this. If you look at the cube above, you will see a white side and if you ignore the corners, you will see a cross. Above the cross, the blue side and next to the white side is the orange side. If those pieces are in the wrong place, the cube can't be solved. This means that you need to line up the center pieces of the blue and orange the corresponding blue and white edge pieces. I know that this can seem complicated, but in practice, this can be one of the simplest parts. I know I just made a whole paragraph on how to make sure you have the right pieces in the right place, but you can't go anywhere without this.

I'm not going to go over how to do these things, just what they are. F2L is putting the white corner pieces and the corresponding edge piece, for example, the white, blue, and orange corner piece paired with the blue and orange edge piece. OLL is where you make the yellow side is made all yellow, this is where the algorithms are put into play. PLL is where you switch the yellow pieces around so they match up with the red, orange, blue, and green sides. All of this solves the whole puzzle

Sorry if I went on a bit of a rant, but hopefully if you read all of this, it makes you understand the Rubik's cube better.

  1. Yes, it isn't complicated. My sister can do the whole thing in 2.5 minutes. Great blog by the way.
