SudokuSolver

For you to play Sudoku with your phone, or solve one for you.

In this app, you can either choose predefined Sudoku puzzles from 4 different levels, or you can create a new puzzle from newspapers or books that you have.

When solving the problem, you can switch on/off the Assist switch, which gives you tip about current possibles.

All predefined puzzles are proved to be solvable, but in "Create" mode, the puzzle you typed in will only be solved if itself is solvable.

More features will come in later version.
