App: American Minefield
Developer: Theodore Mitchell
Genres: Games, Puzzle, Casual

The US has become a minefield, and it is your job to save the American people by locating and dismantling the mines.  Dark green counties are safe and give hints about the amount of danger in neighboring counties.  Mark a county with the green button, and uncover more hints with the red button at your peril.

Four maps come free with the app, and the rest are available as in-app purchases.
