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, helping you reason about safe cells and possible mine locations.
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.
How This Minesweeper Generator Works
Mines are placed after your first click, keeping that cell and its neighbours safe. The generator checks candidate fields with a logic solver and retries when necessary. After a limited number of retries it can fall back to a random field, so later positions are not guaranteed to be 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.
Are all boards solvable without guessing?
The generator tries to find a field that its logic solver can complete, but its random fallback means this is not guaranteed. The first click and its neighbours are always safe.
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.
What are the board sizes for each difficulty?
Easy is 9×9 with 10 mines. Medium is 12×12 with 20 mines. Hard is 16×16 with 40 mines. Expert is 20×20 with 70 mines. The first click and its neighbours are safe on every difficulty.
The Origins of Minesweeper
Minesweeper's roots trace back to a 1960s mainframe game called Cube and later to a 1980 game called Rlogic. Its most recognisable form emerged from the Microsoft Entertainment Pack for Windows in 1990, where it was included primarily to teach mouse skills to users unfamiliar with the new pointing device. The game's designer, Curt Johnson, based it on an earlier game called Mined-Out. By Windows 3.1 in 1992, Minesweeper came pre-installed on hundreds of millions of computers and became one of the most widely played games in history by sheer reach alone. The classic version was eventually removed from Windows 8 in 2012, but countless browser and mobile remakes have kept it alive. This version searches for fields its logic solver can complete, with a random fallback if the retry limit is reached.
How to Read the Numbers
Each revealed number tells you exactly how many of its eight neighbours (including diagonals) contain mines. Working from there:
- A "1" touching only one unrevealed neighbour means that neighbour is definitely a mine — flag it.
- If a number's count of flagged mines equals the number itself, all remaining unrevealed neighbours are safe to click.
- Compare adjacent numbers: if a "1" shares all its unrevealed neighbours with a "2," the cells the "2" has that the "1" doesn't must all contain mines.
- Corners and edges are often the safest starting areas because the constraint math is simpler with fewer neighbours.
- When the board feels stuck, scan for any number whose total unrevealed neighbours equals its mine count — those are all mines and can all be flagged at once.
Logic and Uncertainty in Minesweeper
Minesweeper can reach positions where the visible clues leave several possible mine arrangements. This generator searches for fields that its logic solver can complete, but it falls back to a random field after a retry limit. Use deductions where the clues establish a safe move; a later uncertain position can still require a choice under risk.
