How to Play
- Click any cell to reveal it. The first click is always safe and opens a connected area automatically.
- Each revealed number shows how many of the 8 surrounding cells contain a mine.
- Right-click or long-press a closed cell to place a flag where you think a mine is hiding.
- Click a flagged number cell whose flag count matches its number to reveal all remaining neighbours at once (chord click).
- Reveal every safe cell without hitting a mine to clear the board and win.
About Minesweeper
Minesweeper is a classic logic puzzle where you uncover a grid of hidden cells, using number clues to deduce the location of mines. Each number tells you exactly how many mines touch that cell, giving you everything you need to reason your way to a clear board without ever guessing.
Classic Minesweeper Game Online — Free and No Ads
This is a free Minesweeper game you can play directly in your browser. No download, no install, no account, and no ads. Open the page on your phone, tablet, or desktop and start playing immediately on a clean notebook-style grid.
Four difficulty levels let you choose the right challenge. Easy starts with a 9×9 board and 10 mines. Medium widens the board to 16×9. Hard and Expert scale up the grid and mine density, demanding longer chains of deduction to reach a solution.
No-Guess Minesweeper — Every Board Solvable by Logic
Most Minesweeper generators place mines randomly and accept that some positions require blind guessing. This version generates boards differently: mines are placed after your first click and the result is checked by a constraint-propagation solver — the same logical rules you use as a player. If the board cannot be fully solved by logic, the generator tries again. The puzzle you see is always solvable without guessing.
Minesweeper Strategy and Tips
What makes Minesweeper satisfying?
Every number on the board is a constraint. Two or three overlapping numbers often pin down a mine's location with certainty. The moment you flag a mine and watch adjacent numbers become satisfied — unlocking new safe cells in a chain — is the core reward of the game.
Basic deduction rules
Two rules carry you through most boards. If a number equals the count of its remaining closed neighbours, all of them are mines — flag them. If a number equals the count of its flagged neighbours, all remaining closed neighbours are safe — reveal them.
The subtraction technique
When two numbers share some candidate cells, subtract their constraints. The difference tells you exactly which cells in the non-overlapping region are mines. This technique unlocks positions that neither rule alone can resolve.
Good habits for solving Minesweeper
- Start from the corner of the opened area where numbers have the fewest unknown neighbours.
- Flag mines as soon as you are certain — correct flags let you chord click adjacent numbers faster.
- Use the chord click: when all mines around a number are flagged, clicking that number opens all remaining neighbours instantly.
- Work outward systematically rather than jumping around the board at random.
- Use the Hint button when stuck — it opens one safe cell so you can continue deducing.
Why Minesweeper is a great logic game
Minesweeper rewards careful reading of constraints rather than memory or reflexes. Each number is a small puzzle in itself, and the satisfaction comes from chaining deductions across the board. Even a short Easy session exercises the same systematic thinking used in harder logic puzzles.
FAQ
What is Minesweeper?
Minesweeper is a classic logic puzzle. The goal is to reveal every safe cell on a grid without uncovering a hidden mine, using number clues to deduce where the mines are located.
Is this Minesweeper free?
Yes. No ads, no account, no download. Open the page and play immediately in your browser.
Why does the first click never hit a mine?
Mines are placed after your first click. The clicked cell and all its neighbours are always kept safe, which guarantees a meaningful opening area to start from.
What does no-guess mean?
The board generator verifies that every safe cell can be found by logic before presenting the puzzle to you. You never need to guess randomly — every step follows from the number clues already on the board.
How do I flag a mine on mobile?
Long-press a closed cell to place or remove a flag. On desktop, right-click achieves the same result.
What is the chord click?
Clicking an already-revealed number when the correct number of its neighbours are flagged opens all remaining closed neighbours at once. It speeds up play once you are confident in your flags.
Are my best times saved?
Yes. Your best time for each difficulty is stored locally in your browser. It is not sent anywhere and persists between sessions.
Does this Minesweeper connect to Logic Notebook?
Yes. Clearing a board, improving your best time, and reaching higher difficulty levels all contribute to your Logic Skill and Stamps in My Logic Notebook.
