Minesweeper
Read the land. Trust the clues. Clear your next field.
First dig opens a safe area. Numbers count all eight neighbors.
Tap a square. Tap an opened number to clear around its flags.

Dig opens a square; Flag marks a suspected mine. Right-click or long press also flags. Use arrows to move, Enter or Space for the chosen mode, and F to flag. Opened clues clear their unflagged neighbors when the flag count matches; wrong flags can still hit a mine. Clear every safe square to win. Larger fields pan inside the board. Random fields can require guesses.

How to play Minesweeper
Uncover every safe square without opening a mine. An opened number tells you how many mines touch that square, including diagonally. Use those clues to decide where to dig and where to place a flag. Flags mark your suspicions; they do not prove that a square contains a mine.
Dig, flag and clear around a clue
Choose Dig or Flag, then tap a square. On desktop, right-click also toggles a flag. A short long press flags on touch screens; moving your finger cancels the press so you can pan larger fields. You must remove a flag before digging that square. An empty opening automatically uncovers connected empty squares and their numbered border, while leaving flags closed.
In Dig mode, tap an opened number to chord: if exactly that many neighboring squares are flagged, its other neighbors open together. A matching flag count is not a correctness check. Incorrectly placed flags can expose a mine and end the field. Flags are optional for victory; every non-mine square must be open.
Three classic fields
- Beginner: 9 × 9 squares and 10 mines.
- Intermediate: 16 × 16 squares and 40 mines.
- Expert: 30 × 16 squares and 99 mines.
Mines are placed after your first actual dig. That square and all its valid neighbors are protected, giving you a safe empty opening. Flags placed before your first dig do not start the timer or choose the mine layout. These are ordinary random fields: first-dig safety does not guarantee that every later decision can be solved without guessing.
Phone, keyboard and full screen
Dig and Flag have large, separate buttons. Pan horizontally or vertically inside larger fields; the rest of the page stays within the screen. With a keyboard, arrow keys move between squares, Home and End move across a row, and Enter or Space uses the selected action. F toggles a flag directly; C chords an opened clue. Use Pause to hide the field and stop active time. Full screen keeps the controls together; Back or Escape returns to the page.
Saved progress and fresh attempts
Your current field, flags, active time, preferences and achievements save in this browser when storage is available. Leaving the tab pauses active play. A saved field waits for Resume when you return. If saving is unavailable, an on-screen message explains that you should keep the tab open. Sound starts off, and celebrations respect reduced motion.
A mine ends the current field. There is no Undo or revive. Restart is practice on the same mine layout: it reopens your original first area, keeps the attempt's previous outcome and flag history, and resets the clock. It cannot turn a lost field into a fresh win. New field creates a fresh attempt. Random fields are not guaranteed to be winnable without guessing.
Eight small milestones
Earn stars for a first opening, 25 safe squares in one field, a safe chord, a fresh field cleared, an Intermediate clear, an Expert clear, a fresh clear without ever placing a flag, and three different fresh clears. A fresh clear has no restart or earlier mine hit in that attempt. Reopening a result, restarting or reloading does not duplicate a win. Achievement celebrations stay below the board and never cover a clue.
