About Minesweeper
Minesweeper is a number-based logic puzzle. Open safe squares and use the numbers to infer which neighboring squares hide mines. This free browser game has three classic difficulties, no download and no sign-up.
The first reveal creates a random board and keeps that square plus its neighbors free of mines. This gives you room to begin, but later positions may still require a guess. Flags are your annotations, not verified answers.
How to play Minesweeper
- 01Open a square. The first square and its neighbors are safe; empty spaces open together.
- 02Each number counts mines in the eight surrounding squares. Right-click or use Flag mode to mark a suspected mine.
- 03Reveal every safe square to win. Click an open number when its surrounding flag count matches to open the remaining neighbors. Incorrect flags can trigger a mine.
Minesweeper controls
- Mouse or touch
- Click or tap to reveal. Right-click to flag, or switch to Flag mode before tapping. Large boards scroll inside the play area.
- Keyboard
- Tab into the board. Arrow keys move between squares; Enter or Space uses the selected action. F toggles a flag, and Escape returns to Reveal mode.
- Quick reveal
- In Reveal mode, click an open number when its adjacent flag count matches. All remaining neighbors open together; incorrect flags can lose the game.
Minesweeper difficulties and best times
Beginner: 9 × 9 squares with 10 mines. Intermediate: 16 × 16 with 40 mines. Expert: 30 × 16 with 99 mines. Larger boards have more mines and more clues to compare.
New game and difficulty changes create a fresh round. The timer starts on the first reveal, includes time away from the tab and stops at the result. Each difficulty keeps its fastest winning time in this browser when storage is available; unfinished boards are not saved.
Minesweeper tips and strategies
Use a satisfied number
If a revealed 1 touches exactly one correctly flagged mine, its other hidden neighbors are safe. Count carefully before using quick reveal: a misplaced flag satisfies the count without making the other squares safe.
Compare shared neighbors
A 1 and a neighboring 2 may share the same hidden squares. Once one mine is accounted for in the shared group, compare the remaining squares around the 2. If the available clues do not force a result, acknowledge the uncertainty rather than treating a flag as proof.
- Compare overlapping numbers before making a guess. A flag records your idea; it does not confirm a mine.
- Start with Beginner to learn the patterns, then try larger boards. Random boards are not guaranteed to be guess-free.
Minesweeper patterns and controls
Compare the same covered edge cells across neighboring numbers. The overlaps can show which cells are mines and which are safe.
In both examples, the numbered row is open and the only unrevealed neighbors of each shown number are the covered cells directly above it. Every other neighboring cell is already revealed. These local conditions make the deductions valid; the same number sequence elsewhere may not have the same answer.
1–2–1
The left 1 covers the first and middle cells; the right 1 covers the middle and last. The center 2 covers all three. Together they force mines at both ends, leaving the middle safe.
1–2–2–1
The outside 1s each cover a pair. The first 2 then forces the third covered cell to be a mine; the right 1 makes the last cell safe, and the second 2 forces the other middle cell to be a mine. Both outside cells are safe.

Mark mines, then quick reveal
1. Solve the overlap
For this 1–2–1 edge, the two outside cells are mines and the middle cell is safe.
Flag: reasoned mine · Check: reasoned safe cell
2. Mark both mines
The middle cell stays covered while you mark the two outside cells.
On desktop, right-click both outside cells to flag them.
On a phone, chooseFlagthen tap both outside cells.
3. Quick reveal from 2
Quick reveal opens the safe middle cell, which shows 2.
In Reveal mode, click the open center 2.
On a phone, switch toRevealthen tap the open center 2.
Phone controls
- In Flag mode, tapping a flagged covered cell removes its flag.
- In Reveal mode, a flagged cell stays closed; tapping it does not reveal it.
- Swipe or scroll inside the board to reach cells on larger boards.
Quick reveal checks only whether the flag count matches the number; it does not verify flag positions. A wrong flag can make the count match and expose a mine. If the count differs, nothing opens.
Minesweeper FAQ
Is this Minesweeper free?
Yes. Play here without a download or account.
How do I win?
Reveal all squares that do not contain a mine. You do not need to flag every mine.
Is the first click safe?
Yes. Mines are placed after the first reveal, outside that square and its neighboring squares. Placing a flag does not start the timer.
Are all boards solvable without guessing?
No. These are random classic boards, not certified no-guess puzzles. The safe first reveal does not guarantee that every later move can be deduced.
Do I have to flag every mine to win?
No. Reveal every non-mine square. Flags only protect squares from accidental reveals and help track your deductions.
Can I play on a phone?
Yes. Use Reveal and Flag modes. Each cell has a touch target of at least 40 pixels; swipe or scroll inside the board for larger difficulties.
Where are my records stored?
Winning times are kept separately for each difficulty in this browser. They do not sync across devices. If storage is unavailable, the game still works.
Can I play at school or work?
The game needs no installation or account, but access depends on your network rules. This site cannot guarantee that a network will allow it.
