White corners

Read more

Place the four white corners to finish the white layer. White stays on top, with one short algorithm for each way white can face.

Goal

Finish the whole white layer. The top is all white, and the top row of each side matches its center.

How to recognize it

A white corner has three colors, one of them white. Its spot is between the three centers with exactly those colors.

How to hold the cube

Keep the white cross on top, as in the last lesson. The target spot is always the top front right, closest to you.

Steps

  1. Find a white corner in the bottom layer.
  2. Turn the bottom (D) until the corner sits right under its spot.
  3. Turn the whole cube so that spot is at the top front right.
  4. See where the white sticker faces, then do the matching algorithm.
  • White faces right: R' D' R.
  • White faces front: F D F'.
  • White faces down: R' D2 R D R' D' R.

Memory tips

The first two are mirrors: the right hand does R' D' R, the left hand does F D F'. The third turns the corner so white faces a side, then inserts it like the first.

Corner stuck in the top layer

Is a white corner on top but in the wrong spot or twisted? Hold it at the top front right and do R' D' R to drop it into the bottom layer. Then follow the steps above.

Check before moving on

The top is all white. The top row of each side matches the center of that side.

Common mistakes

  • Putting a corner into a spot that is not between its three centers.
  • Misreading where white faces and picking the wrong algorithm. Look at the white sticker first.
  • Turning the cube over. In this lesson white stays on top.

Next lesson

Go to Middle layer. From then on, the white layer goes on the bottom.

Step 1 / 3

R': Right face: turn 90°, front face goes down

White faces the right side.

The corner is in the bottom layer, right under its spot. White cross on top, its spot at the top front right.

Step 1 of 3: R'. Right face: turn 90°, front face goes down
