Everyone can enjoy solving this brain-teasing puzzle! Now, Sudoku lovers can take their puzzle-solving fun to a new dimension. This puzzle combines the benefits of Sudoku and Cubing into a single game, providing a mind-bending challenge for all. The challenge of the Sudoku Cube is to get the numbers 1 through 9 on each of the six sides of the cube at the same time. # The Goal of Game The object of the puzzle is to arrange the cube in such a way that each cube face shows the digits 1 to 9 with no duplicate digits, similar to what you might see in a 3x3 block of the popular Sudoku puzzles. 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. # How to Play This app presents the cube in 3D with a smooth sliding operation, and you can change the perspective by tilting the phone, just like playing a real cube. Swipe across the cube to rotate one layer, and swipe across the blank area to rotate the whole cube. To start playing the game, click the Scramble button and the stopwatch will start. # FEATURES - 3D realistic graphics makes you feel playing with real cube. - Swipe the cube with your finger to rotate the layer of cube. Swipe through the blank area to rotate the cube. - You can also tap the Undo button to undo the last action. - Tilt the phone horizontally or vertically to change the viewing angle of the Rubik's Cube. - 3 cubes: 3x3x3, 4x4x4, 5x5x5 - 3 colour schemes Suggestions or questions?
