Octacube

Octacube (by Mindope) is a type of mind-teaser puzzle made up of eight cubes with colors on the faces. The object of the puzzle is to arrange the eight cubes into a 2×2×2 cube such that all faces show the same color on the inside and all external colors which magneticly touch are the same color. There are seven colors in the puzzle, and each of the eight cubes shows the seven colors, one per face.
