Minesweeper is a single-player computer game. The object of the game is to clear an abstract minefield without detonating a mine. The game has been rewritten for nearly every system platform in use today. The most well-known version comes bundled with later versions of Microsoft Windows. The Windows version credits Robert Donner and Curt Johnson as its creators, but the game's origins can be traced back to a paper-based gambling game in the 1950s, and as a computer game to Cube from 1973.
