Sudoku Cube

You know Sudoku: numbers 1 to 9, each row, each column, each box exactly once. Sounds manageable, right? The Sudoku Cube sees it differently and literally turns the classic puzzle in all directions.What you have in front of you is a rotating cube based on the Rubik's Cube principle, but instead of colored surfaces, numbers reign supreme. Your goal: arrange all six sides so that each displays the numbers 1 to 9 completely.Perfect for anyone who finds ordinary Sudoku too two-dimensional. Solving optional, frustration included. A strenuous brain workout guaranteed. ;)
