MQBE

MQBE is a puzzle based on Professor Ern” Rubik's Magic Cube (called Bv”s Kocka in Hungarian), the 20th century's most amazing puzzle.
In the late 70s and early 80s the Cube became a world-wide fad. While fads come and go, for some of us the Magic Cube remains as fascinating as ever. After all, there are not too many puzzles that offer 43,252,003,274,489,856,000 patterns. To have seen all possible patterns, if you could have viewed 1,000 patterns every second, you would have had to start when the universe was born.
Each of the six surfaces of the cube (Top: BLUE, Bottom: WHITE, Front: ORANGE, Back: RED, Left: GREEN, Right: YELLOW) are made up of nine squares. The central square on each surface can never change its position, but all of the other squares can be rearranged as slices of the cube are rotated clockwise or counterclockwise. When the slices are rotated, the colors on the cube's surfaces are scrambled, reset, or pretty patterns can be created. The primary purpose of the puzzle is this: given a random pattern, find the minimum number of rotations that will restore the colors to their original pristine positions.
