Some grass blocks hide mines. Dig the safe ones! Each number tells you how many mines touch that spot. Plant flags where you think the mines are.
Win games to unlock new fields to dig in.
Click or tap a grass block to dig it. Right-click, long-press, or switch to Flag mode to plant a flag. Your first dig is always safe. Tap a number that already has the right number of flags around it to dig all its other neighbours at once. Drag to turn the camera a little, pinch or use the mouse wheel to zoom, or use the buttons. Win games in a row to build your streak and unlock new themes.
