Every Orientation of the Last Layer case for CFOP, grouped advice on recognition and a learning order.
How to learn OLL algorithms
OLL (Orientation of the Last Layer) makes the last face one colour without disturbing the first two layers. Full OLL has 57 cases; 2-look OLL splits the job into edge orientation and corner orientation.
Recognising OLL cases
Look at the top-colour edge stickers first: do they form a cross, a line, an L shape or a dot? Then check the corners and the top-colour stickers on the sides.
Group full OLL cases by their top pattern, such as square, lightning, T, P, W or C shapes. Similar top patterns can have different side stickers, so inspect both before choosing an algorithm.
Headlights are two corner stickers of the same colour facing the same side. Note their location and any adjacent blocks, then align the cube to the orientation shown for the case.
A practical OLL learning order
Begin with 2-look OLL: orient the edges to make a cross, then orient the corners. The F R U R' U' F' sequence (OLL 45 here) is a useful edge-orientation building block.
Learn the seven corner-orientation cases with the cross already formed: OLL 21–27 in this library, including Sune and Antisune. These finish the corner-orientation step of 2-look OLL.
Move into full OLL one small pattern group at a time. Start with cases you already recognise and sequences you find comfortable; there is no compulsory order for all 57.
Mix your new cases with older ones in practice. Check recognition before turning, and keep your 2-look approach available for cases you have not learned yet.
Remembering algorithms and finger tricks
Say the case's recognition cue before executing it. Break the sequence into familiar triggers, such as R U R' U' or R' F R F', and practise the joins slowly. Alternate similar-looking cases so you learn to distinguish them, not just repeat one sequence.
