Step 2/4 · Faster reduction

Last two centers

Read more

Seven cases for the last two neighboring centers, each with one short algorithm. Includes the fix for fully swapped centers.

Goal

Solve the last two centers once the other four are done. Each case needs one short algorithm.

How to hold the cube

Yellow on top, white on the bottom. The last two centers are on the front and right faces. Here the front is blue and the right is red.

How to recognize it

Count the blue pieces on each face, then see whether they form bars or diagonals. The seven cases below differ in those two things.

Memory tips

  • The algorithms use only R, F and the horizontal slices Uw, Dw. Outer turns never break a center.
  • Every Uw or Dw is undone later, so the top and bottom centers stay put.

Common mistakes

  • Finishing with the two centers fully swapped. Use Centers fully swapped instead of starting over.
  • Holding the last two centers at the front and back. They must be next to each other, at the front and right.

Step 1 / 4

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

The front has a red piece in its top right spot. The right has a blue piece in its top left spot.

Yellow on top, the red piece in the top right spot of the front. The algorithm swaps the two pieces through the lower slices.
