Sudoku Puzzles, which some refer to as Rubik's Cube of the 21st century, are now also available in the shape of a 3x3 Rubik's cube.
Called Sudokube, this puzzle is effectively a Rubik's cube, but instead of being made of colours, it is made of numbers. You play Sudokube in the same way as you would a Rubik's Cube, but you need to get the numbers aligned on each side as you would in a Sudoku grid.
And if you hate spending that $10 on a Sudoku cube, get hold of a normal Rubik's cube and glue numbered labels to each of the cube edges as shown in the figure. If you have old date calendar at home, you can cut the digits from that calendar and glue them on the Rubik's cube. Happy solving.
