How to use flags

Flags are used to mark tiles which you suspect may hide a mine. Putting a flag on a tile prevents you from clicking on it and possibly causing an explosion, which would end the game.

The exact look of the flags depends on the theme. You can change the theme by pressing the menu button in the top-right corner of the window and then selecting Appearance.

How to place a flag on a tile

Flags cannot be clicked. To place a flag on a tile:

  • right click on a blank tile.

Use of the question flag

If you are not sure whether a tile hides a mine, you can use the question flag.

To put an I'm not sure flag on a tile:

  • Right-click twice on a blank tile or once on a flag.

To enable these flags, press the menu button in the top-right corner of the window and enable the Use Question Flags preference.
