Mine Logic

Read the numbers to find safe cells. No guessing required.

Choose a tool, then tap a cell. Repeat to erase a mark.

Use arrow keys to move and Enter to act. Scroll the enlarged board to reach every cell.

How to play

Each number counts mines in the eight surrounding cells. An open blank cell has no neighboring mines. Flag confirmed mines and open confirmed safe cells. Open every safe cell and flag every mine to finish. A safe region is already open, and every puzzle can be solved without guessing. You can undo an accidental opening.

Once a number has enough neighboring flags, its other neighbors are safe. When its remaining mine count equals its unknown neighbors, all of them are mines.
