A 2 at the very edge of a wall adjacent to two hidden tiles means they're both mines.Be very careful, because while this technique is useful (and integral), if you fail a spot check and don't see that there's already a mine diagonal to your 1, you will probably die. Why? Because there's only one available tile adjacent. If you have a 1 on a corner, it's a mine.Minesweeper is known to have quite a few little strategies: Middle-clicking a number with a matching number of flags adjacent to it uncovers all squares adjacent to it that are not flagged, which will set off a mine if even one flag is in the wrong square. Right-clicking places flags where you think there's a mine. That number tells you the number of adjacent mines. By left-clicking any square on the grid, you will either open a new area, detonate a mine or find a number. The levels will affect the size of the board (9×9, 16×16, 16×30) and the number of mines (10, 40, 99) respectively. When you start the game, first you must select the difficulty: beginner, intermediate or expert. Minesweeper is a nice little puzzle game packed with every version of Microsoft Windows up to Windows 7.
