MineSaver is a minesweeper screensaver and solver written by Patrick Craig.


Patrick Craig (UK) started playing minesweeper in 1995 while completing his Biological Computation MSc at York University. During this time he wrote a program for himself to solve Minesweeper. After completing his degree he converted the program into a screensaver.

The program works on Windows 98 and earlier versions. Put it in the 'Windows/System' directory and rename the 'exe' to 'scr'. You can adjust solving speed by changing display properties, either by right-clicking on the desktop or via the Control Panel. At top speed Beginner and Intermediate are solved in 1 second and Expert is solved in 2 seconds. On default settings Expert is solved in just under a minute. The program cycles through each level, playing each one until it wins. The solver does not read memory so it loses after incorrect guesses. Lost games result in one of three responses; 'Blast', 'Damn', or 'Oh Dear'. Success messages include 'Yes' and 'Cool'. Smiley faces appear in the background while solving and count from 8 to 1 before turning into brightly coloured circles.


MineSaver was the first and so far only screensaver for minesweeper enthusiasts. It was also one of the first solvers.
