Memsweeper is a clone of Minesweeper, a single-player computer game where the object of the game is to clear an abstract minefield without detonating a mine. Memsweeper introduces a twist on the original game. Every block references a point in memory. 'Safe blocks' reference allocated memory, while the 'mines' point to unallocated portions of memory. Clicking on 'mines' induces failure within the software itself. The space of play has been shifted from representational failure to real computational failure. The stakes are much higher in this version.
