A new daily set is ready.
Swipe sideways to explore the field, or choose Fit board.
Open the leaf to begin. Your first opening is safe.
Right-click or hold a tile to flag. Keyboard: arrows to move, Enter reveal, F flag, H hint.
Every daily board has been checked by our logical solver from its marked safe opening. A path to the finish exists using revealed numbers and the mine total. No-guess describes the board: you still choose which moves to make, and a mistaken move can uncover a mine.
Open a tile to reveal a clue: its number counts mines in the eight surrounding squares. Flag places you think contain mines. A layered hint starts with clues to examine, explains a deduction, then offers a move you can apply. Hints use visible numbers rather than looking up a hidden mine.
Try the three shared daily boards, then generate a fresh practice field. Entries, flags, elapsed time and rewards save in this browser. There is no countdown. Undo lets you recover from a mistaken move; a shared result records hints and mine rescues.
