Brain teasing 3D Sudoku Cube

Sudoku puzzles have titillated our grey cells for long but are still reasonably enticing by testing our mettle and entertaining us at the same time. This new 3D Sudoku Cube blends a Rubik cube of 3×3x3 cubes with Sudoku. Just rearrange the 70×70x70mm cube so that each face shows digits 1 to 9. Easy, isn’t it?
