OLL 29
The algorithm, how to recognise it and how to practise it without cheating.
Recommended algorithm
R U R' U' R U' R' F' U' F R U R'13 moves
How to recognise it
Yellow on top: the back and left edges and the two right corners. The front-left corner's yellow faces you.
Its inverse is another case
Do the 29 algorithm backwards, R U' R' F' U F R U R' U R U' R', and you are solving 44.
That's why CubeDojo never scrambles 29 that way: it builds a random state with the case fixed, so you practise 29 and not 44.
