How to restore the picture of Rubik's cube

First of all, if you want to restore the Rubik's cube, you must first understand its structure. The Rubik's Cube has six colors and six faces, which are generally red, yellow, blue, green, white and orange. Each face is divided into central blocks (six in the middle), corner blocks (eight in the four corners) and side blocks (middle of four sides 12). Among them, the central block has only 1 face, which is a fixed structure, so if the central block is red, all other reds should be concentrated on this face. And the red central block is always opposite to the orange central block (stipulated by international standards). Each side block has two faces and two colors, and each corner block has three faces and three colors.

Next, we will use letters to represent each face.

Then put its bottom edge back in place (also known as the process of correctly restoring the bottom cross and four bottom edges)

Return to the bottom corner (restore the four corners of the first layer of the Rubik's Cube):

Equation 2- 1: (r ur')

Formula 2-2: (f' u' f)

Put the white corner block back in place.

Step 3: restore the middle edge (the step of restoring the four middle edges of the Rubik's cube):

Equation 3- 1: (u 'f 'u f) (u r u 'r')

Formula 3-2: (u r u' r') (u f u f)

Plane position of the top edge (also known as the top box cross, the color of the top surface of the top four edge blocks is the same as the color of the top center block):

Equation 4: f (r ur' u') f'

Vertex surface position (the step of adjusting all the top surfaces of the four corners of the Rubik's cube to the top surface):

Equation 5-1:r' u2ur' u r

Equation 5-2:u' r u' r u' r u' r u' r u' r

Vertex homing (the other two faces with four vertex angles of one face are the same color as the central block of the corresponding face):

Equation 6:R2

eight

Top edge homing (the color of the other side of the positioned four top edges is the same as the color of the center block of the other four surfaces):

Equation 7: (r u 'r) (u r u) (u r u r) (u r u R2)
