A LOGIC GAME WITH A QUICK START
What is Minesweeper?
Read clues, then choose a safe square
Minesweeper is a single-player logic puzzle played on a grid of covered squares. Some squares hide mines. Open a safe square to reveal a number showing how many mines touch it, including diagonals. Use those clues to work out which nearby squares are safe and which should be marked with a flag.
A round ends when you reveal every square without a mine. You do not have to flag every mine to win, but flags make your deductions easier to track. This version gives each new board a safe first move and supports keyboard, mouse, and touch controls.
The clue counts all eight surrounding squares, including diagonals. A 1 means exactly one neighboring square contains a mine; a 0 means no neighboring square contains a mine and can reveal a useful open area automatically.
Pick a board that matches your experience
Beginner uses a 9 by 9 grid with 10 mines. Intermediate uses 16 by 16 with 40 mines. Expert expands to 30 by 16 with 99 mines. Each difficulty has its own personal best and leaderboard, so quick wins on a small board are not compared with a larger one.
The timer starts with your first move. Finish the board to record a time, then try again to improve it. The online ranking keeps your best time for each period and difficulty; your personal records also stay in this browser.
The timer starts when you reveal the first square, so you can choose a difficulty and get comfortable with the controls first. Use the zoom controls to fit or enlarge the board, especially on Expert and smaller screens. Personal bests stay in this browser, while leaderboard submissions are grouped by difficulty and period.
Return for the shared daily board
The Daily Challenge gives every player the same seeded board for the day. Its leaderboard is separate from Classic, and the fastest successful clear ranks highest. Choose a difficulty, study the opening clues, and make each move count.
The game is designed for short sessions on desktop, tablet, and mobile. On a phone, use Reveal and Flag mode buttons so the board stays comfortable to tap without relying on a right-click.
The shared layout changes at 00:00 UTC, and each difficulty has its own daily board. A daily attempt belongs to the UTC date when you started it, so restart after midnight if you want a result on the new ranking. Choose Classic for a fresh random board at any time.
Build a steady routine for reading clues
Start with a number whose covered neighbors are easy to count. If its value matches the number of covered neighboring squares, those squares are mines. If it matches the flags already around it, every other covered neighbor is safe. Check diagonals and compare overlapping clues before you make a move.
On desktop, right-click a covered square to add or remove a flag. On a phone, select Reveal or Flag before tapping. Clicking an open number also tries to open its remaining neighbors when the nearby flags satisfy the clue, a shortcut called chording. Flags are optional for winning: open every safe square to clear the board.
- Count diagonal squares as neighbors.
- Combine clues when they share covered squares.
- Use flags to organize your reasoning, then verify them against the numbers.
