Nine-Colour Cube Nine-Colour Cube The Nine-Colour Cube ("see below" for other names) is a cubic twisty puzzle. It was invented in 2005 by Milan Vodicka and mass-produced by Meffert's seven years later. Mechanically, the puzzle is identical to the Rubik's Cube; however, unlike the Rubik's Cube, which only has 6 different colours, the Nine-Colour Cube has 9 colours, with the individual pieces having one colour each. The puzzle is known under several different names. Milan Vodicka, the inventor, initially gave it the name "Nine-Colour Scramble Cube", which reflected the key feature and the "de facto" objective of the puzzle. This name was
N-dimensional sequential move puzzle the 2D puzzle cannot be scrambled at all if the same restrictions are placed on the moves as for the real 3D puzzle. The moves actually given to the 2D Magic Cube are the operations of reflection. This reflection operation can be extended to higher-dimension puzzles. For the 3D cube the analogous operation would be removing a face and replacing it with the stickers facing into the cube. For the 4-cube, the analogous operation is removing a cube and replacing it inside-out. Another alternate-dimension puzzle is a view achievable in David Vanderschel's Magic Cube 3D.
