Move the four yellow corners into place with one algorithm, done once or twice.
Goal
Move the four yellow corners to their spots. The top stays yellow; the edges may still be out of place.
How to recognize it
A corner is in its spot when its two side colors match the two centers next to it. Look only at the corners.
Steps
- Turn the top (
U) until at least two corners are in their spots. This is always possible.
- All four corners right: go to the next lesson.
- Two correct corners side by side: hold them at the back, then do
R' F R' B2 R F' R' B2 R2 U'.
- Two correct corners diagonal: do the algorithm once. Turn
U and hold the two correct corners at the back, then do it again.
Memory tips
The algorithm is long but has a rhythm: R' F R', B2, R F' R', B2, then R2 U'. The two middle beats are alike, with F changed to F'.
Check before moving on
Turn U to test: at some point all four corners match their centers. The top is still yellow.
Common mistakes
- Looking at edges instead of corners.
- Holding the two correct corners at the front instead of the back.
- Forgetting the final
U'.
