Mindsweeper — a principled take on minesweeper

An excellent online and open-source version of minesweeper. Notably, every game can be won with logic alone (no guessing needed).

I'd suggest playing this with the following settings to minimize tedium and maximize fun:

• grid: evil
• mode: autopilot (also, try with "normal" to see the difference)
• punish guessing: on
• subtract flags: on
