Ever wondered how your Sudoku solving skills compare to others? Competitive player?
Well now you can solve Sudoku puzzles and see how your score compares to others solving the same puzzles.
Each day (North American East Coast Time), a new puzzle will be available for three different difficulty levels. Your score will be recorded and published (if you wish) so that you can rate yourself against your friends and others. When solving the puzzle, all the solve aids (including checking your input) will not be available.
