Nine-Colour Cube other, there is no parity constraint; all of the above positions are attainable. The full number is therefore: Out of the 268 240 896 000 possible configurations, there are 80 that represent a solved puzzle. These solutions fall into three categories: 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
Sudoku Cube are the Sudokube and Roxdoku, as well as cubes with 4×4×4 squares instead of the normal 3×3×3. This cube is very difficult compared to other cubes because as well as requiring basic knowledge of a Rubik's cube, the player must also know basic sudoku concepts. Any wrong move could put the puzzle in jeopardy. 3-D programming languages such as VPython can be used to create simulations of a Sudoku Cube. Such simulations can offer features such as scaling the sudokube (to create 4×4×4 or 5×5×5 puzzles), saving, resetting, undoing, and the option to design one's own sudokube patterns. Sudoku Cube
