A Sudoku Cube is an extremely challenging puzzle that combines the 3-dimensional spatial relations of a Rubik's Cube and the mathematical algorithms of Sudoku. In order to solve the Sudoku Rubik's Cube, the numbers 1 through 9 must appear on each face of the cube, although not in any particular order.

Brush up on your Rubik's Cube skills before attempting to solve a Sudoku Cube. You can visit a site like Doing the Cube to learn how to solve the ordinary Rubik's Cube in a minimal amount of time (see Resources below). While the Sudoku Rubik's Cube is considered much more difficult, playing with a Rubik's Cube will help to develop your spatial-relations skills.
Solve the Sudoku Rubik's Cube by learning the ultimate objective of the puzzle. Unlike traditional Sudoku, the numbers 1 through 9 do not need to be in order, as they must merely be represented once on each 3-by-3 grid face. In addition, the numbers will be oriented in the same direction on a properly solved puzzle.
Use a pencil and a piece of graph paper to help you solve the Sudoku Rubik's Cube. By drawing a diagram of an "unfolded" cube and entering various numbers on the grid as you solve the puzzle, you can use mathematical algorithms to solve the puzzle in the same way as traditional Sudoku.
Start the Sudoku Rubik's Cube by noting that the center square is fixed and will ultimately determine the orientation of the other numbers on that particular face of the cube.
Find the right corners to each face of the Sudoku Rubik's Cube. By noting the orientation of each corner number, you should be able to solve the 16 corners with relative ease.
Find the correct edge numbers between the corner squares, and solve the edges one at a time. Ensure that you are not undoing what you have already solved by writing down the numbers of each edge as you go along.
Tips and warnings
- You may want to use a traditional Rubik's Cube and turn it into a Sudoku Cube by placing adhesive stickers on each square. The original cube is much easier to turn than the newer product, with much smoother action between the squares.
