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
Professor's Cube them make up the supporting frame and these have extensions which hold rest of the pieces together. This allows smooth and fast rotation and creating arguably the fastest and most durable version of the puzzle. Unlike the original 5×5×5 design, the V-Cube 5 mechanism was designed with speedcubing in mind. The original Professor's Cube is inherently more delicate than the 3×3×3 Rubik's Cube because of the much greater number of moving parts. Because of the fragile design the Professor's Cube is not suitable for speedcubing. Applying excessive force to the cube when twisting it may result in broken pieces. Both
