About Minesweeper
Minesweeper is a game of pure deduction dressed up as a game of luck. Behind the grid sits a fixed number of hidden mines, and every safe square you uncover shows how many mines touch it. From those numbers alone — no guessing required, most of the time — you can reason out exactly where the mines must be, flag them, and clear the rest. The famous first-click gamble gives way, within seconds, to satisfying chains of certainty: this 1 touches only one unknown square, so that square is a mine; this 2 is already satisfied, so its other neighbours are safe. Speed comes later, once the logic is second nature and you are racing your own best time. This version offers classic difficulties, works with mouse or touch, tracks your fastest clear, and never buries a solvable board under a forced guess. It is the thinking person's five-minute break.
How to play
- Click any square to start — your first click is always safe.
- A number tells you how many mines touch that square, including diagonals.
- Right-click (or turn on the 🚩 Flag toggle on mobile) to mark squares you think hide a mine.
- Reveal every safe square to win. Click a mine and the game is over.
Strategy & tips
- Start from the big open areas: a revealed zero automatically opens all of its neighbors, giving you free information.
- If a number already touches exactly that many flags, every other neighbor is safe — this is the game's most-used deduction.
- A "1" on a wall or corner is your best friend: it has fewer neighbors, so its mine is easier to pin down.
- When two numbers overlap, subtract what they share — patterns like 1-2-1 and 1-2-2-1 have fixed, learnable solutions.
- Never guess while a certain deduction exists somewhere on the board. Scan everything before you gamble.
FAQ
Can I lose on the first click?
No. Mines are placed after your first click, so the first square you reveal is always safe.
What do the numbers mean?
Each number counts the mines in the up-to-eight squares touching it, including diagonals. A blank square means zero adjacent mines.
How do I flag mines on a phone?
Tap the 🚩 Flag toggle above the board, then tap squares to flag them. Tap the toggle again to go back to revealing.
How many mines are there?
This board is the classic beginner setup: a 9x9 grid with 10 mines. The mine counter shows how many are left unflagged.
