The one, a very difficult Bandaged Puzzle, is advancement of the famous Wall/Burr Cube 4*4. It’s also difficult to scramble the puzzle as well as Burr Cube. One has to think well to break and mix up central elements. In order to start a long way to a solved puzzle. As well as in a previous version 4*4, it’s possible to twist inner units of cubes 2*2 & 4*4 along the central axis.I’ll be probably solving it till doomsday. http://player.youku.com/player.php/sid/XMjg3NjMzNzcy.swf
