Minesweeper is a puzzle video game created by Microsoft in the 1990s. The game was written by Robert Donner and Curt Johnson. Johnson stated that Microsoft Minesweeper's design was borrowed from another game, but it was not Mined-Out, and he does not remember which game it was. The game gained great popularity in the 90s and 00s among Windows PC users, as it was preinstalled in the operating system.
The board is divided into cells, with mines randomly distributed. To win, you need to open all the cells. The number on a cell shows the number of mines adjacent to it. Using this information, you can determine cells that are safe, and cells that contain mines. Cells suspected of being mines can be marked with a flag using the right mouse button.
