I remember a long time ago (20 years ago?) playing some Windows minesweeper variant that someone had wrote. It did the "impossible to hit a mine on your first click" thing (That I believe Windows' Minesweeper didn't do), but also had different shapes. You could have a hex map, for example. Anyone know what I'm thinking of?
