This algorithm is one of the essential OLL cases. It helps you orient the last layer more efficiently.
About This Case：
OLL27 is a three-corner-up pattern with one corner dark, giving it an uneven look.
Recognition：
Three yellow corners are oriented; one remains white.
Memory Hint：
27–28–29 form a family—start by checking which corner is the odd one.
Execution Tips：
Keep the cube level; tilted angles make this case harder to read.
