# NxNxN Rubik's Cube Scrambler

On official WCA competitions they use not only the classic 3x3x3 Rubik's Cube but other cubes like the 2x2x2 Pocket Cube, the 4x4x4 Rubiks Revenge, the 5x5x5 Professor's Cube up to the 7x7x7 cube. With this online NxNxN cube scrambler you can generate random permutations for cubes up to order 11, the 11x11x11 Rubik's Cube being an existing puzzle.

Scrambles: Set how many scrambles you want to generate. This number may vary from 1 to 99 and it must be a valid integer. The bigger this number is the longer it takes the program to finish the calculations.

Length: Set the length of one scramble. For bigger puzzles like the 11x11x11 you'll need more turns to scramble it properly so you can increase this number to up to 999 moves. To see how the unscrambled puzzle looks, set this number to 0.

Separate: Long scrambles may be easier to read if there's a break after every five moves. Activating this checkbox the program will insert separators into the algorithm for a better readability.

Orient: On official WCA competitions cube puzzles and Megaminx are scrambled with the white face on top and the green face on the front. If this is not possible then the lightest face on the top and the darkest adjacent face on the front. Check this box if you need a random initial orientation for the puzzle.

FRU only: ie Front-Right-Up only. Set this if you want to use only these rotations.

## Notation of the NxNxN Rubik's Cube puzzles

If you are familiar with the notation of a classic 3x3x3 Rubik's Cube then you must know that this affects only the outer layers of the puzzle. This is enough to scramble a 2x2x2 Pocket Cube and a Rubik's Cube but for the 4x4x4 and bigger cubes we need to reach the inner layers too.

We marked every face of the cube with a letter which by itself means a clockwise rotation of the certain face and the letter followed by an apostrophe means a counterclockwise rotation:

• F: front clockwise
• R: right clockwise
• U: up clockwise
• B: back clockwise
• L: left clockwise
• D: down clockwise
• F': front counterclockwise
• R': right counterclockwise
• U': up counterclockwise
• B': back counterclockwise
• L': left counterclockwise
• D': down counterclockwise

The index numbers in the algorithm shows you how many layers you have to turn together:

• F2 - turn two (the first and second) front layers clockwise
• R3' - turn three right layers counterclockwise
• U32 - turn three upper layers 180°

For more examples or to see this in action please set the scramble length to 1 for a 11x11x11 cube and do some scrambles.
