Simple Sudoku (free, no ads)

Play easy, medium, or hard Sudoku games. Your score is based on your board difficulty: Hard boards increment by 1 every second, Medium every .9 seconds, and Easy every .8 seconds. Lower scores are better! You can enter a name to use on your local leader board or use one of the auto-generated names. The boards are complete with highlighting currently selected rows, columns, and boxes, as well as all instances of the selected number. At any time you can get a Hint for your selected square, or you can show the solution to a puzzle.
