Stage 6 — put the last corners home

The top is all yellow now, but the corners may be in the wrong spots. Look for a corner that is already in the right place — its two side colours match the centres either side of it.

Hold that corner at the front-right and run U R U' L' U R' U' L. This cycles the other three corners around.

Repeat until all four corners are home. If no corner is correct to begin with, run the sequence once from anywhere and one will appear.
