Basic gameplay works just like you are used to: Try to uncover all squares.
Left-click a square to tell you how many mines are adjacent to it. If you accidentally left-click a square that contains a mine, it's game over. Uncover all the squares and you've won.
There is also a timer; Try to play as fast as you can to uncover all the squares to beat your previous time.
To help you keep track of which square may have a mine, you can right-click a square to place a marker. Right-click again to remove the marker.
When you uncover all the squares, the smiley face wears shades, which means all is dandy.
