Microsoft Minesweeper

Microsoft Minesweeper (formerly just Minesweeper, and also known as Flower Field) is a minesweeper-type video game created by Curt Johnson, originally for IBM's OS/2, that was ported to Microsoft Windows by Robert Donner, both Microsoft employees at the time.

The goal of Minesweeper is to uncover all the squares on a grid that do not contain mines without being "blown up" by clicking on a square with a mine underneath. The location of most mines is discovered through a logical process, but some require guessing, usually with a 50-50 chance of being correct.
