Play Minesweeper

Minesweeper is a free online puzzle game.  This game's objective is to clear a rectangular board comprising hidden mines without detonating some of them, together with assistance from clues regarding the number of nearby mines in each area.

Clear all of the squares on the board that do not have mines, and flag all of the mines.  Left-click your mouse to reveal hidden bits.  Use the numbers you find to figure out where the mines will be: each number tells you how many the surrounding eight tiles (up/down, left/right, or diagonal) are all mines.  Once you've figured out which a mine is, then click on it to put a flag there.  How fast can you clear the entire board?
