Sudoku Kube is effectively a Rubik's cube, but instead of being made of colours, it is made of numbers. The idea of the game is to get the numbers 1-9 on each side of the cube. You play Sudoku Kube 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. In this game you really have got the best of both worlds.
