To mark a mine you add 'M' (eg, D7M) and to flag you add '?' (eg, D7?). You move by entering the co-ordinate (eg, D7). Most of these games were found in the archive of abandoned programs at. It seems strange now, but the original Minesweeper (1990) had a menu option to play in monochrome in case the user did not have a colour monitor. For example, CGA (1981) had 16 colours, EGA (1984) had 64 colours, and VGA (1987) enabled 256 colours. Many DOS games mention what graphics are used. All games here have been tested using DOSBox or Windows 3.1. If you are using a 64-bit version of Windows you need to use a DOS emulator, such as the free DOSBox. In fact, DOS games are fully supported on Windows until 98/ME and will work on most later 32-bit versions, while they are fully supported on all OS/2 versions and their successor eComStation (2001). Both can be used on Windows (1985) or OS/2 (1987) because Microsoft was involved in writing both operating systems. The EXE files are a type (MZ) native to MS-DOS. The COM files are an older format used by an early operating system called CP/M, and since MS-DOS derived from a clone of CP/M it also used the COM extension but made its COM files incompatible. MS-DOS games are 16-bit programs which are either COM or EXE files.

Microsoft published Windows Minesweeper in October 1990 so DOS versions are not historically important except for the fact a different DOS game called Relentless Logic inspired the creation of Minesweeper. DOS refers to a group of similar operating systems with the most famous being MS-DOS (1981) by Microsoft, which was sold as PC-DOS on IBM computers. This is a collection of minesweeper games for DOS.
