Safe Cells
Open every safe cell and flag every mine — one wrong click ends the run.
Open a cell to see its number.
A number counts the mines hiding among its eight neighbours. A cell with no mines beside it opens its whole neighbourhood at once.
A number counts the mines hiding among its eight neighbours. A cell with no mines beside it opens its whole neighbourhood at once.
Once a number has exactly as many flags beside it as its count says, opening it again opens every other unflagged neighbour in one move.
A flag is a note, not a proof — it blocks an accidental open and feeds a chord. It never counts toward solving on its own.
There is no undo and no second guess at a mine — the board stays exactly as it was, exploded. Every day has a path through found by deduction alone. Stuck? A hint opens a safe cell or flags a mine. In ranked play, each hint adds 15 s.
Tap a cell to open it, long-press (or toggle flag mode) to flag a mine, tap an open number to chord its unflagged neighbours · keyboard: arrows move, Space or Enter opens, F flags, C chords
