Covert Sudoku Free for Everyone app for iPhone and iPad

This is an advanced-level version of our fun puzzle game. To play, the user enters 1-9 like in Sudoku or Number Place, only there’s one HUGE difference between this app and other puzzle games: it’s designed to look like a calculator—which means that anyone who sees you playing this game would think you’re hard at work! The numbers are easy to read, and the buttons are incredibly user-friendly. Since the level of difficulty ranges from Average to Difficult, everyone from beginners to seasoned players will love this one. It can generate a virtually infinite number of games, so you’ll never, EVER get bored. But sometimes you might get stuck....when that happens, you can press the Show Hints button to get some clues. And whenever you solve a puzzle, the Facebook Upload button appears. Impress your friends with all your wins!
*Remember, if you give up and hit Solve, the Facebook Upload button won’t display, but you can use the Hint button and still Upload when you solve.
