How to play

9×9 with 10 mines, and the mine map is hidden from both players alike — the two views are identical.
Opening a safe cell scores +1 for every cell it newly opens.
Hitting a mine scores -1 and passes the turn; the field never floods for you.
When the safe cells run out, the higher score wins and equal scores draw.
