Algorithm

RU2R'U'RUR'U'RU'R'

11 moves. Execute with the solved layers on the bottom and the last layer on top.

Setup / recognition

Apply this scramble to a solved cube to reach the OLL 21 case so you can practise it on demand:

z2RUR'URU'R'URU2R'

Category: All Corners Oriented. This is one of the cases you recognise by the shape the top stickers form before the algorithm.

About this case

OLL 21 (H Cross) is an OLL case — the orientation step of CFOP. All corners oriented, H pattern on top. Once the last layer is fully oriented, the top face shows a single colour and you move on to PLL to permute the pieces into place.
