Welcome, Surveyor
Read the numbers. Each revealed number counts the mines touching it. Deduce which hidden tiles are safe and which are mined.
Flag and chord. Right-click (or long-press, or flag mode) to flag a mine. Click a satisfied number to chord — clear all its neighbours at once.
Speed and cleanliness score. Faster solves with fewer wasted clicks earn more. Harder minefields multiply your points on the leaderboard.
Sounds, music and themes live under Settings.
