Formulas to solve Rubiks cube
On this page you can read about formulas, what they are and how they are denoted.
A formula is a prescribed number of turns performed consecutively. Formulas are an important tool in solving Rubik’s cube. Using formulas you can get pieces of the cube in their places while preserving solved parts of the cube. They are presented in a specific format on this site. The abbreviations used in formulas are explained below.
Sides of the cube
The sides of the cube are abbreviated as follows:
- F = Front side
- B = Back side
- L = Left side
- R = Right side
- U = Up side
- D = Down side
Turning a side
All sides of the cube can be turned in two ways, clockwise and counterclockwise. The starting point is an imaginary clock on the concerned side, looked upon from outside the cube. A quarter turn in a clockwise direction is noted by means of the letter abbreviation of the side which is turning. So:
F = Front side turning, one quarter turn, in the clockwise direction.
To denote a counterclockwise turn, the letter i (for inverse) is added. So:
Ri = Right side turning, one quarter turn, counterclockwise.
Below, a number of pictures of a solved cube whereof one side has been turned a quarter.
Notation of formulas
The individual turns are denoted in the format above and are separated by commas.
Example of a (simple) formula:
Formula: F, Ri
First turn Front side clockwise, then turn Right side counterclockwise.
Turns concern sides of the cube that rotate, not a cube that rotates as a whole.
In addition to side turns, some formulas also contain slice turns, which are inner layer turns. The slice turns on this site concern the layer between the Left side and the Right side.
