Sudoku Puzzle Solver will solves Sudoku problem within seconds. Sudoku Puzzle Solver has been tested with various Sudoku difficulty levels; easy, medium, hard & expert, it never fails as long as the puzzle is valid. Sudoku Puzzle Solver is easy to use as it is really straight forward. Just tap the cell where the value is known & set it as required by choosing the correct number for the cell. Repeat the process until all known cells are filled. Once all done, just tap SOLVE to let Sudoku Puzzle Solver app do the magic. All the solved cells will be highlighted in green for your reference. It will also tells you if the puzzle that you have provided cannot be solved or an invalid puzzle after it has finished checking. In this case, you have to re-checked, whether the Sudoku puzzle supplied is not matching the Sudoku puzzle that you wanted to solve, perhaps you have input one or more values in the wrong cells. Before solving any Sudoku Puzzle, you can also tap the PEEK button to view all the possible values for each cells for that given Sudoku Puzzle. This is useful if you want to solve the Sudoku Puzzle manually without using the auto solve solution, this way the Sudoku Puzzle Solver app will just act as a helper to you. If you see an empty cell while using the PEEK feature, this means that there is no possible value for that cell (the end). Note that you have to tap on PEEK button everytime after you have updated any cells to update as it will not auto update for you. So what are you waiting for, get Sudoku Puzzle Solver app now & start solving those super difficult Sudoku challenge & puzzle out there in seconds. ** Note that there were very few extremely difficult Sudoku puzzle that we have tested requires a little bit of time to solve them (our record max is 22s). So please be patient while waiting, should you encounter one of the type, thank you & ENJOY!
