You are in a field that has been divided into squares. Mines have been planted under 99 of those squares. Your task is to plant flags on all the squares that have been mined and to clear all the other squares and to do it as quickly as possible.

Right-clicking on a square plants a flag and left-clicking on a square clears it. The counter in the upper left corner is the number of mines left to discover, assuming that all your flags have been planted on squares that actually are mined. If you clear a square that actually is mined, the mine explodes and the game is over.

When you clear a square, the number that appears in the square is the number of adjacent (horizontally, vertically and diagonally) squares that are mined. When you start the game a small area of the board is cleared so you do not have to begin the game guessing blindly.

Good Luck!
