This algorithm is one of the essential OLL cases. It helps you orient the last layer more efficiently.
About This Case：
OLL15 is a chunky horizontal Knight Move pattern, featuring a wide 2×2 block and an offset sticker.
Recognition：
A 2×2 square with one extra yellow forming a wide, horizontal pattern.
Memory Hint：
Identify the wide block first, then the offset piece—this combination uniquely defines OLL15.
Execution Tips：
U and U' are frequent; practice left-hand U flicks to keep the algorithm fluid.
