The goal of the game is to uncover every square without a mine under it. By uncovering a mine, you will lose.When you uncover a square, it will display a number that describes how many mines are in the surrounding eight squares. You can place a flag on a square to signify that it has a mine under it. You do not need to place flags to win, but they sure are helpful! If you have marks selected, you can flag the square once more to mark it as a possible mine. You cannot uncover flagged squares, but you can uncover marked squares, so be careful. To unflag or unmark a square, flag or mark it again. If you get too frustrated, you can start a new game and try again!
