3x3 Notation
In cubing, "notation" refers to the system of symbols and letters used to describe moves on a cube. It allows cubers to follow along with "algorithms" (a sequence of moves that are required for switching specific pieces on a cube). Here’s an overview of the basic 3x3 notation:

Double Layer Moves
Whilst the WCA doesnt official use double layer moves, some other algorithms may use them. Double layer moves like 'f simply mean you move the FRONT 2 layers clockwise (the same would work with 'r' or 'd'). You can also get double layer moves for a 180 degree rotation in which case you would see something like 'f2' (meaning you would rotate the front 2 layers 180 degrees). In some other articles or websites you may see these are 'Fw' or 'Dw' (meaning Front Wide or Down Wide).
Face Turns
Each letter represents a face of the cube that should be turned:
- R (Right)
- L (Left)
- U (Up)
- D (Down)
- F (Front)
- B (Back)
A letter without any additional symbols means a 90-degree clockwise turn of that face. A letter with an apostrophe (e.g., R') means a 90-degree counterclockwise turn. A letter followed by the number 2 (e.g., R2) means a 180-degree turn in either direction.
Notation Examples
- R U R' U': This notation represents a sequence of moves for algorithms commonly used in solving.
- R2 D2 F2: Each move here turns the respective face 180 degrees.
