Rubik's Cube Recovery Guide

Answer 1

The following is a Rubik's cube restoration tutorial:

** 1. Restore the white cross on the bottom (Take the third-order Rubik's cube as an example)**
1. First, he turned the white prism block to the bottom and aligned the color of the prism block with the center block. If the position of the edge block was wrong, it might need some adjustment of the edge change formula, such as the operation formula "top, outside, bottom, inside, top" and so on.

2. He could also use some small tricks, such as turning the white edges on the side or on the top by moving the white edges aside.

** 2. Restore the bottom and middle corner blocks (Third-Order Rubik's Cube)**
1. He found a corner block with a white color on the top floor and looked at the matching color of the corner block. For example, the corner and prism were orange and blue, and the orange-blue prism had to be found on the top floor. If the top floor didn't have one, he would choose a white corner block and its matching prism block combination.
2. He adjusted the corner block that he found to the top of the corresponding center (such as the orange-blue center), and operated different formulas according to different situations to restore the bottom corner block and the middle prism block at the same time. For example, the formulas "Right Turn Down Right Up","Right Up Left Down Right Up Right Down","Left Up Left Down Right Up Right Down","Right Up Right Down Right Up Right Down","Right Up Right Down Right Up Left Down", etc.

** 3. Readjust the top floor's orientation (Third-Order Rubik's Cube)**
1. Make the top color the same as the center color (e.g. all yellow). If the top image was a yellow center and two diagonally opposite yellow corner blocks forming an oblique line, the two sides with the same color on the side would face the back (or the side with a single color would face the position of the right hand). The operation formula was "up, left, down, left, down, up, reverse, left, down, up, reverse".

** 4. Adjusting the color of the side (Third-Order Rubik's Cube)**
1. When the three corners on the side were in the wrong position and the edges were in the right position, according to the specific direction of the corner (such as the counterclockwise rotation direction, etc.), the corner with the correct position of the corner was placed in the upper left corner. The operation formula was "up, back, up, down, back, up, down, up, up

For the second, third, and fourth level of the fifth-order Rubik's cube:
1. First, look at the color of the big pillar. If the top is blue and on the left-hand side, use your left hand to hook up and back down.
2. Then, he turned the Rubik's cube around, and White made a hook up and down for himself.
3. Find a group without a red color. After matching it, if the top is red and on the left-hand side, tick it up and back down.
4. He turned around and made a hook on himself.
5. For the rest of the groups, if they were aligned, they would hook up and down on the left hand side, then turn around and hook up and down on themselves in blue. If the last group was on the right, they would first hook up and back with their right hand, then turn around and hook up and back with their left hand.
