Sudoku (free, no ads)

Play easy, medium, or hard Sudoku games for free and with no ads! The game boards are complete with highlighting currently selected rows, columns, and boxes, as well as all instances of the selected number. The number buttons keep a count of how many times they currently appear on the board. At any time, you can get a Hint for your selected square, or you can show the solution to a puzzle. If you don't want to finish a game right away, no worries! You can exit the app and pick up where you left off later by selecting the same difficulty and then selecting "Resume". You can enter a name to use on your local leader board or use one of the auto-generated names.
