Developer’s description of game: Sudoku for the iPhone.
Sudoku on the iPhone is played exactly the same as Sudoku anywhere else. The point of the game is to use the numbers 1-9 only once in a row, column and 3×3 box. It starts off by giving you a screen in which some of the numbers are already filled in…you go from there. You can add a number by clicking in a blank box, it will give you the number 1, to change it from a number 1 you just keep tapping until you have the number you want. If you get stuck and your brain starts to hurt from trying to figure it out, you can start over with a new game by hitting “new.” There is also a “check” button that tells you whether or not you really solved the puzzle. This game is TOTALLY addicting and one of my favorites. Sudoku is available through the Conceited Software source. Screenshots:
