Covert Sudoku iPhone app for iPhone and iPad

This puzzle game, created especially for i-Phone, works just like Sudoku or Number Place: the user inputs numbers 1-9 in the blank spaces to solve the puzzle. Designed so that you can play Sudoku even on the sly, this game looks like a calculator instead of a game, featuring easy-to-read numbers and simple-to-use buttons!
This is a very user-friendly game. In case you get stuck, just press “Show Hints” to display some possible answers in the blanks—one will be the right one! The game can also be saved in the middle, so you don’t even need to finish all at once—you can keep going back to it anytime you have a free moment. The user can also save screenshots of any puzzles solved. So solve lots of puzzles, save screenshots of all of them, and show your friends how smart you are! For times when you just need to give up on a puzzle, press the Solve button to see the entire set of correct answers. For info on the rules, refer to the Help guide.
The paid version of this game can be played an unlimited number of times, so keep on playing!
