The letters in the formula represent the front of F- Front, the opposite side of B- Back, and the side facing away from you (you can't see it). The edges, corners and central blocks on the left side, left side, right side, top side and D -Down bottom of the Rubik's Cube are angles of two colors, and the central blocks of three colors are fixed on the surface.
In the process of constructing the top-level cross floret, it is necessary to put four white edges on the top with a yellow central block.
To complete the bottom span, this step needs to turn the small flower pieces to the bottom, and the positions and colors of the bottom four pieces should be correct.
To complete the repair of the bottom layer, it is necessary to put four white corner blocks on the bottom layer to complete the bottom layer, and the position and direction of the corner blocks need to be correct.
To complete the repositioning of the second layer block and four second layer blocks, the position and direction of the second layer block need to be correct, and the four sides of the top layer without yellow need to be restored in turn.
There are four situations in restoring the third-floor span. You need to adjust the direction of the four top edges to build a yellow cross. When building a yellow cross, you don't need to look at the position of the top edge or the top corner.
This step is to transfer the yellow faces of the three corner blocks on the top floor to the top floor. These two cases are simple mirror images, but the formulas used in these two cases can also deal with the remaining five cases. The upper part of the graph is two simple cases.
The other five top colors are solved here. You can use the two formulas in the sixth step to restore the top color. You need to rotate the Rubik's Cube between the two formulas.
In this step, there are two situations in which the four corners of the third floor are returned. In the second case, four corners can be returned by two formulas.
Restoring the third-level Rubik's Cube (the last step of the Rubik's Cube, after this step, your Rubik's Cube will be restored) will encounter two basic situations and special situations, and the two formulas used in the sixth step also need to be superimposed and restored.
