When two layers are collected from the Rubik's cube, it remains to collect the last, third, layer. First of all, you need to collect the "header" of the upper face.
Instructions
Step 1
First you need to collect the cross on the upper side. It is not necessary, however, that the adjacent median rib cube stickers match the color of the central element of the adjacent side. There are three cases of assembling the cross.
Step 2
In the first case, when there is already one horizontal line of the cross, we raise the front part 90 ° clockwise, move the right part 90 ° away from ourselves, turn the upper edge 90 ° clockwise, turn the right part 90 ° towards ourselves, set the top edge 90 ° counterclockwise, rotate the front side 90 ° counterclockwise. The cubes fall into place, and a cross is obtained on the upper side.
Step 3
In the second case, when an angle has formed on the upper side, we turn the front side 90 ° clockwise, move the upper side 90 ° clockwise, move the right side 90 ° away from ourselves, twist the upper edge 90 ° counterclockwise, we lower the right side by 90 ° towards ourselves, turn the front face 90 ° counterclockwise. The missing cubes fall into place, and a cross is obtained.
Step 4
In the third case, when only the central element of the cross is present on the upper face, we apply the rotations from the first or second case. Then, depending on the formed figure, we perform rotations from the first or second case again.
Step 5
After assembling the cross, we proceed to further assembling the "cap" of the upper face, replacing the missing elements. There can be seven situations here.
Step 6
In the first situation, when almost the entire "header" is assembled, with the exception of two elements that are located on the sides of adjacent faces, we take the cube so that the "header" looks up, and one of the missing elements looks at itself and is in the upper right corner. Next, we turn the right side 90 ° towards ourselves, set the front edge 90 ° counterclockwise, turn the left side 90 ° towards ourselves, rotate the front edge 90 ° clockwise. Then we move the right side 90 ° away from ourselves, rotate the front edge 90 ° counterclockwise, move the left side 90 ° away from ourselves, rotate the front edge 90 ° clockwise.
Step 7
In the second situation, when the two missing elements look forward, we move the left edge 180 ° away from ourselves, turn the lower part 90 ° counterclockwise, rotate the left part 90 ° towards ourselves, move the upper edge 180 ° counterclockwise. Next, move the left edge 90 ° away from ourselves, rotate the lower edge 90 ° clockwise, rotate the left side 90 ° towards ourselves, move the upper edge 180 ° counterclockwise, rotate the left side 90 ° towards ourselves.
Step 8
In the third situation, when one of the two missing elements is on the back side in the upper right corner, we rotate the right side 90 ° towards ourselves, turn the front edge 90 ° counterclockwise, move the left side 90 ° away from ourselves, rotate the front edge 90 ° clockwise. Then we move the right side 90 ° away from ourselves, turn the front edge 90 ° counterclockwise, rotate the left side 90 ° towards ourselves, turn the front side 90 ° clockwise.
Step 9
In the fourth situation, when three elements are missing in the "header", one of which is on the left side edge in the far upper corner, we move the right side 90 ° away from ourselves, rotate the upper edge 180 ° clockwise, lower the right side to 90 ° towards yourself, twist the upper part 90 ° counterclockwise. Then we move the edge 90 ° away from ourselves, rotate the upper edge 90 ° counterclockwise, lower the right side 90 ° towards ourselves.
Step 10
In the fifth situation, when three elements are missing, one of which is located on the front side in the upper right corner, move the right edge 90 ° away from ourselves, rotate the upper edge 90 ° clockwise, lower the right side 90 ° towards ourselves. Then we turn the upper edge 90 ° clockwise, rotate the right side 90 ° away from ourselves, rotate the upper edge 180 ° counterclockwise, lower the right side 90 ° towards ourselves.
Step 11
In the sixth situation, when four elements are missing, which are located on the front and back faces in the upper corners, we rotate the front side 90 ° clockwise, then we perform the following turns 3 times: move the right side 90 ° away from ourselves, twist the upper part 90 ° clockwise, lower the right side 90 ° towards ourselves, rotate the upper edge 90 ° counterclockwise. Next, turn the front side 90 ° counterclockwise.
Step 12
In the seventh situation, when four elements are missing, two of which are on the left side face in the upper corners, and the other two are located on the front and back faces in the upper corners, we perform the following rotations. Move the right side 90 ° away from ourselves, turn the upper edge 180 ° clockwise, rotate the right side 180 ° away from ourselves, turn the upper edge 90 ° counterclockwise. Next, move the right edge 180 ° away from ourselves, rotate the upper edge 90 ° counterclockwise, move the right side 180 ° away from ourselves, rotate the upper edge 180 ° counterclockwise, move the right side 90 ° away from ourselves.
Step 13
After the completed rotations, the top in the last layer of the Rubik's cube will be collected. All that remains is to put the corner and edge elements in their place in this layer.
