Play Classic Minesweeper Online! This online version of the game brings together the classic with a newer theme. The goal of Minesweeper is to clear the board without hitting a single mine. The numbers that appear on the squares indicate how many mines surround that block - horizontally, vertically and diagonally. For example, a square with a 2 mean there are two mines touching that square. Play 3 different skill levels - Easy, Medium or Hard. The harder the level, the bigger the board and the more mines!
