Rubik's The Void Puzzle

There's an extra challenge when solving this puzzle-because something's missing! There's a hole where there should be a middle. The VOID is amazing to see, to touch and to contemplate. Its movement is more magical than any other puzzle of its kind. Scramble The VOID's vibrant rings, then try to restore a solid-colored ring on each sidde. Doing so is a feat of cosmic proportion.

For ages 8 & up.
