OLL 22 · the Pi
All four edges already point up, and all four corners still lean over. Nine moves finish the yellow face.
All four edges already point up. Only corners are left to turn, which makes these the cases beginners see first in the two-look method.
In this case all four edges already point up, and all four corners still lean over. The algorithm turns every last sticker of the top face yellow in one pass; where the pieces then sit is the next stage's problem.
Cubers know this one as the Pi. Names like this survive because solvers see the shape thousands of times and talk about it.
One last layer in fifty-four arrives exactly like this. The diagram shows the top face as you would see it from above, yellow where yellow already shows, with the outer ticks marking where the missing yellows currently point.
Checked by simulation before publishing: the position shown plus the moves shown must produce a finished cube, and the algorithm must touch nothing outside its own job. The diagram and the player are drawn from the same simulated position, so they cannot disagree.
