The standard notation system used by speedcubers worldwide to write down moves and algorithms. Every letter represents a specific turn — learn them once and you can read any algorithm.
The six basic moves. Each letter refers to a face of the cube. A plain letter means a 90° clockwise turn (as if you're looking at that face).
Suffixes that change how a face turn is performed. These apply to any face move.
Lowercase letters turn two layers at once — the outer face plus the adjacent middle layer. Common in advanced algorithms.
These turn only the middle layer between two opposite faces. Essential for algorithms like the H-Perm and Z-Perm.
Rotations turn the entire cube without moving any layer relative to another. They change your perspective but don't affect the solve state.
Algorithms are written as a sequence of moves separated by spaces. Read left to right and execute each move in order.
