How to recover if the Rubik s Cube flashes? How to recover the Rubik s Cube

It's the Rubik's Cube that box stupid hat, the function Rubik's Cube software sweep.

Here's how to restore it:

1. Find a random color first, and directly restore it to a complete surface.

2. Four-sided bottom layer and center block restoration: take the complete surface of the first step of restoration as the bottom, restore the trapezoidal shape formed by the bottom layer and the center block of the four sides (as shown in the figure below) while the second step is completed, the side of the first step is still intact, and there is no trace of luck in these two steps, so if you want to complete the reduction of the Rubik's Cube, the above two steps are the most basic, and this needs to be explored and practiced by yourself.

3. The "plus" and "subtraction" in the Rubik's Cube formula refer to "clockwise" and "counterclockwise" respectively: the complete surface completed in the first step has been used as the bottom surface, and the face facing itself is the "front", and the lower two layers of the four sides are complete, which refers to the complete restoration of the lower two layers of the four sides (as shown in the figure below), and the formula is: the moving block is the middle block of the upper layer on the side, and it is judged according to the color of the side whether it moves to the left side of the middle layer or moves to the right side:

Middle left square subtract up, subtract left, add up, add left, add up, add up, add up, subtract up, subtract before; The center and right squares are added up, right, subtracted, subtracted, subtracted, subtracted, subtracted, added, added.

4. Restore the top layer of the cross: After completing the third step, the next step is to restore the top layer of the cross (as shown in the figure below), the specific formula is: front plus, right plus, top plus, right subtraction, top subtraction, front subtraction.

5. The square block on the top layer of the four sides (cross homing): the square in the top layer of the four sides, that is to say, the square in the middle of the top layer of the four sides corresponds to the center block of the middle layer (as shown in the figure below), the formula is: first of all, the condition is to find the only side of the four sides that can be opposed, and this side is the "front", and the others are not faced.

If there are two sides that can be matched, use the following formula once, and you can achieve the conditions for using the formula: right plus, plus up, right subtract, add up, add right, add 180 degrees, right subtract.

6. The alignment of the squares on both sides of the top layer of the four sides (the corners of the upper layer are aligned): the squares on the top two sides of the four sides are aligned, which refers to the alignment of the squares at the upper corners of the four sides, and the homing does not mean that the color should be aligned, as long as the color of this piece corresponds to the color of the three sides, as shown in the figure below. The mantra is:

First of all, the condition is to find a counterpoint angle and put it on the top right of the top layer of the "front" surface, if you can't find the counterpoint, you can use a formula, you can see the counterpoint: up, right, up

7. The completion of the top layer refers to the completion of the matching of the color of each side of the four corners of the top layer in the state of the four corners of the sixth step (as shown in the figure below), the formula is: right subtraction, bottom subtraction, right addition, bottom addition, right subtraction, left subtraction, right addition, bottom addition (repeatedly use this formula, each pair of upper corners, is to use a "plus" and then complete the next corner).
