OLL 5
The algorithm, how to recognise it and how to practise it without cheating.
Recommended algorithm
r' U2 R U R' U r7 moves
Alternatives
(U2) l' U2 L U L' U l7 moves · with the left hand
How to recognise it
A yellow 2×2 square on top. Hold it at front right: the front side shows no yellow.
Its inverse is another case
Do the 5 algorithm backwards, r' U' R U' R' U2 r, and you are solving 8.
That's why CubeDojo never scrambles 5 that way: it builds a random state with the case fixed, so you practise 5 and not 8.
