WHITE ON TOP · LEFT EDGE FLIPPED

F2L case 21: white on top · left edge flipped

Algorithm

RU'R'U2RUR'

It takes 7 moves: R U' R' U2 R U R'. Do them in one go, without pausing: the step-by-step below shows the cube right before each turn.

Hold the cube with the white cross on the bottom, the green centre in front and orange on the right. The pair —the white-green-orange corner and the green-orange edge— goes into its slot at the front right. For the other three pairs, turn the whole cube until their slot is at the front right and use the same algorithm.

The video is in Spanish, but the moves are the same in every language.

Step by step

The pair is in full colour with a black outline, the first two layers in normal colour and the yellow layer faded, because its position doesn't matter for this case.
