About Minesweeper
Minesweeper asks you to clear a grid without detonating any of the hidden mines beneath it. Every safe square you uncover shows a number: how many mines touch that square, counting all eight neighbours. Those numbers are the entire information channel, and the whole game is the deduction you build from them.
It is far more a logic puzzle than a game of luck, which is the part newcomers usually miss. The opening click is a genuine gamble, but from the first numbers onward most moves are provable. The two rules that carry most of the game are simple: if a square's number equals the count of unopened neighbours, every one of them is a mine; if its number equals the flags already around it, every remaining neighbour is safe. Apply those repeatedly and large regions unravel. Only occasionally does a board present a genuine coin-flip. This version offers easy, medium and hard grids with flagging and a timer.
How to Play Minesweeper
- Left-click any square to uncover it. The first click is always safe.
- Read the numbers — each one counts the mines touching that square across all eight neighbours.
- Right-click a square to flag it as a suspected mine and keep track of your deductions.
- Uncover every safe square to win. Detonating a mine ends the game.
Tips & Strategy
- Learn the two core rules. If a number equals its unopened neighbours, they are all mines; if it equals its surrounding flags, the rest are safe.
- Work the edges and corners first. They have fewer neighbours, so their numbers constrain far more tightly than numbers in open space.
- Flag deliberately rather than defensively. Flags are what let the second rule fire, so accurate flagging is what makes regions cascade open.
Frequently Asked Questions
A number is the count of mines in the eight squares touching it, including diagonals. A 1 means exactly one of its neighbours is a mine.
No. The first click is always safe, which is why the board only becomes solvable from that point onward.
Mostly not. After the opening, the large majority of moves are logically provable. Genuine guesses come up occasionally, but a player who deduces properly wins far more often than one who clicks hopefully.
No. You win by uncovering every safe square. Flags are a bookkeeping aid for you, not a win condition.
