Rubik's cube

When solving a Rubik's cube, the process involves multiple steps focused on organizing different layers and aligning stickers correctly. A common challenge arises when the middle layer isn'

8. Position upper layer Edges

F2 U’ R’ L F2 L’ R U’ F2
counter clockwise
F2 U R’ L F2 L’ R U F2
clockwise

7. Position the upper layer Corners

Swap corners
You may need to do this twice to move diagonally
L’ U R U’ L U R’ R U R’ U R U2 R’

6. Solve the Yellow face (top face)

1 corner sticker = position cube as above, then action algorithm
0, 2 matching corner stickers = position yellow corner to the X, then action algorithm
R U R’ U R U2 R’

5. Create the Yellow cross (top face)

Orient cube with yellow stickered top face as above, then perform the algorithm Ultimately, this will result in a yellow cross
F U R U’ R’ F’

4. Solve the middle layer

Occasionally you will find no edge pieces in the top layer without yellow stickers but the middle layer is not solved. In such cases, displace the matched middle-layer edge piece by performing the left or right trigger. There should now be an edge piece in the top layer without a yellow sticker. Solve for it as described above.
Identify edge pieces on the top layer that do not have yellow stickers. Once you find an edge without a yellow sticker, rotate the top face of the cube until the outward facing sticker on that edge piece is directly over the center piece of the same color. Once it matches, look at the upward-facing sticker on that edge piece. That sticker will match the center on either the left or the right. If it matches on the right, perform the following algorithm: U + Right Trigger Doing so will disturb the first layer. Fix the displaced white corner sticker as you did in step three. If it matches on the left, perform the following algorithm: U’ + Left Trigger Doing so will disturb the first layer. Fix the displaced white corner sticker as you did in step three.

3. Solve the first layer

If you have an outward facing white sticker in the bottom layer, face it toward you and position the cube so that it is either in the bottom left or bottom right corner of the side facing you, and perform either the left or right trigger, respectively, to relocate it to the top face of the cube.
If you have a white sticker facing the top, position the white sticker over something that is not white (because it will disrupt whatever is underneath), and, depending on if the piece is on the right or on the left, perform a double trigger
Look for white stickers on the top layer that face the sides. Each white sticker should be on a corner piece with three stickers. Rotate the top face of the cube so that the sticker beside the white sticker that is also outward facing (i.e., not the sticker on the top) diagonally matches the center of the same color. Once you’ve paired them, face the color-matched stickers toward you. If the matched sticker in the top layer is right of the center, perform the Right Trigger. If the matched sticker is left of center, perform the Left Trigger.
Triggers
Right Trigger = R U R’
Left Trigger = L’ U’ L

2. Create the White Cross

For the rest of the solve, the white cross will be on the bottom
For each petal on the “daisy,” match the non-white sticker to the center piece of the same color. Once matched, turn the face with the matching center two times. Repeat this process three more times. When you are finished, the bottom face of the cube will have a white cross.
