How it works
Six mines are placed after your first reveal, outside that cell and its eight surrounding positions. A number counts mines among the neighboring cells, including diagonals. Open all 30 safe cells to win; revealing a mine ends the round.
A useful example
A 1 touching exactly one covered cell identifies that cell as a mine if all its other neighbors are open. If a 1 already touches one correctly placed flag, its other unmarked neighbors are safe. Flags are your notes, not proof.
There is no clock. Start from an edge of the revealed area, compare neighboring clues and avoid guessing until the available deductions are exhausted. Some positions still require a guess.
