What Is This?
Minesweeper is a classic logic game played on a grid that hides a fixed number of mines. Every safe cell you reveal shows a number telling you how many mines sit in the eight cells around it. From those numbers you work out where the mines are, flag the ones you are sure about, and reveal every safe cell to win. A single click on a mine ends the game, so the whole game is about reading the numbers and never taking a step you cannot justify. This browser version keeps the classic rules with three difficulty levels. Beginner runs a small grid with few mines, Intermediate scales it up, and Expert gives you a large board where careful counting matters on every move. There is no account and no download, and the timer records how fast you clear each board. The first click is always safe, which lets you open the game without needing a lucky guess.
How to Play
- Choose Beginner, Intermediate, or Expert, then click any cell to start. Your first click is always safe.
- Each revealed number counts the mines in the eight cells that surround it.
- Right-click a cell on desktop, or long-press on mobile, to flag a cell you believe is a mine.
- Clear every non-mine cell to win the board. Revealing a mine ends the run.
- If a cell has as many flagged neighbors as its number shows, the rest of its neighbors are safe to reveal.
- Use the timer to compare how fast you clear the same difficulty across sessions.
How the Score Is Calculated
Your result is how quickly you clear the board, and the timer runs from your first click to the last safe cell. There is no point system, so a clean, steady clear beats a frantic one full of flips and missed flags. The timer rewards smooth logic, not speed of clicking, because a fast player who makes one mistake and detonates gets no score at all. A win is always a better result than a loss, even if the winning time is slower, because minesweeper is a logic game before it is a speed game. Your best clear time on each difficulty is saved on your device, so you can chase it on the next board. The size of the grid and the number of mines change with the difficulty, which is why Expert times run so much longer than Beginner ones. That steady progress is the point: each difficulty is a ladder, and the time you beat on one level is the time you bring to the next.
Tips to Improve
- Start in the middle of the board. Your first click is safe, and opening a wide area gives you many numbers to work from at once.
- Work from the edge of revealed areas inward. Cells on the boundary have the clearest logic because their unknown neighbors are few.
- When a number equals the count of its flagged neighbors, every other neighbor is safe. That is the single most useful rule in the game.
- When a 1 touches exactly one unknown cell, that cell is a mine. Flag it before touching anything near it.
- Count carefully around a 2 or 3. Working out the count in your head beats flipping cells and hoping.
- If a flag is wrong, everything downstream is wrong. When you doubt a flag, unflag it and recount before revealing.
- Guess as late as possible. Most beginner and intermediate boards can be solved with logic alone; only expert boards occasionally force a choice.
Common Mistakes
The most common mistake is flagging carelessly. A wrongly placed flag blocks your count, and the confusion usually leads to a misjudged reveal a few cells later. The second mistake is revealing a neighbor of a number before checking whether it should be flagged first. A cell showing a 1 with one unknown neighbor is a mine, and revealing that neighbor detonates it. The third mistake is rushing. Minesweeper punishes speed with a loss far more often than it rewards it, so a steady scan of the numbers is the difference between clearing a board and restarting it. Finally, do not treat a lost game as a failure of logic; some expert boards genuinely come down to a guess, and even strong players lose those.
