This cube looks like a 4x4x4 professor cube but turns like a 2x2x2 because of internal bandaging making it impossible to turn any single layer. What sets this cube apart from being just a 2x2x2 or 4x4x4 is while it turns like a 2x2x2 you can also do 180 degree turns on the edge pairs. Zygmunt's Cube is a very easy puzzle to solve but very fun to play with.
