Sudoku Solver
 
Enter in a sudoku game and this applet will solve it using logic rather than a brute force test of possible combinations. Note that some of the more difficult sudoku puzzles can't be solved by this applet because it isn't programmed to look ahead multiple steps.
Instructions:
- Left-click on an empty space to select it, then type in a number.
- Once all numbers are entered press the 'Solve' button.
