For official WCA scrambles hold the hold the Megaminx with WHITE top and GREEN front.
Cube Notation is letters and letter character combinations to describe specific turns on a Megaminx. The purpose of notation is to easily describe an algorithm or a scramble.
IMPORTANT: For the Megaminx, the notation used for scrambles differs from the notation used to describe algorithms.
Official WCA Scramble Notation:
In the official WCA Megaminx scramble notation, there are three types of turns: Right, Down, and Up. For the Right and Down turns, you will always perform a double turn. A "++" indicates a clockwise turn, while a "--" signifies a counterclockwise turn.
For Megaminx Algorithms we use a different notation. The images below illustrates the turns.
