Corner sideways, different top colors

Read more

Corner and edge both on top, the white sticker faces sideways, and the top colors differ. Move them apart, then join them.

Goal

The corner and edge are both on top, and the corner's white sticker faces sideways. The two top colors differ.

How to recognize it

The color on top of the corner differs from the color on top of the edge. Then check whether white faces front or right, and where the edge is.

These two pieces cannot be joined right away. The algorithm splits them, then joins them again.

How to hold the cube

White cross on the bottom, the empty slot at the front right. Turn the top until the corner is at the top front right.

The main idea

As in the last lesson, the first half makes the pair and the second half is a case from F2L basics. Here the second half is always Insert from the right or Insert from the front.

For example, in U' R U' R' U R U R' the first half U' R U' R' splits and rejoins the pieces. The second half U R U R' is Insert from the right after one U.

Check before moving on

The front right slot is done, and the cross and other slots are untouched.

Common mistakes

  • Mixing up a white sticker facing front with one facing right. Look at the corner before you start.
  • Skipping the U at the start of an algorithm. It puts the pieces where the algorithm expects them.
  • Doing y' and forgetting that the slot is now at the back right.
  • Turning D and knocking the cross out of line.

Next lesson

Go to Corner with white facing up.

Step 1 / 9

y': Whole cube: turn 90°, front face goes right

The white sticker faces front, the edge is at the top front, next to the corner.

White cross on the bottom, the empty slot at the front right. Do y' first, so the slot moves to the back right.

Step 1 of 9: y'. Whole cube: turn 90°, front face goes right
