Minesweeper

How to play: clear every square that has no mine under it. A cleared square shows how many of the eight squares around it are mined, and a blank one opens its neighbours for you. Where you are sure a mine is buried, flag it: right-click the square, or turn on Flag mode so that taps plant flags instead of digging. The counter tracks how many mines you have yet to flag. Your first dig is always safe; after that, one mine ends the game.
