Minesweeper Rules: How to Play Online

Minesweeper is a puzzle game where you clear a minefield without detonating any hidden bombs. You click squares to reveal them; numbers indicate how many mines are in adjacent cells. Right-click or long-press to flag suspected mine locations. Your first click is always safe, and you can 'chord' by clicking a satisfied number to reveal surrounding squares.

Minesweeper, a timeless classic, challenges players with a simple yet engaging puzzle. On Play Online Games, you can enjoy this strategic game directly in your browser, whether you are on a phone, Chromebook, or desktop. Understanding the basic rules is key to clearing minefields and improving your game.

Understanding the Basics of Minesweeper

The goal of Minesweeper is to clear a hidden minefield without detonating any bombs. When you start a game, the board is covered. You begin by clicking any square. Importantly, your first click is always safe and will never be a mine, giving you a clear starting point.

Once you click a square, one of two things happens: either it reveals an empty space, or it reveals a number. An empty space means there are no mines directly adjacent to it. A number, however, tells you exactly how many mines are located in the eight surrounding squares (or fewer, if it's near the edge of the board).

As you uncover numbers, you use logic to deduce where mines might be hidden. If you suspect a square contains a mine, you can mark it with a flag. On Play Online Games, you do this by right-clicking on a desktop or performing a long-press on a touchscreen device. Flagging helps you keep track of potential mine locations and prevents you from accidentally clicking them.

Advanced Play: The Art of Chording

Once you become comfortable with the basic click-and-flag mechanics, you can incorporate a technique called 'chording.' Chording allows for faster gameplay and is a hallmark of experienced Minesweeper players. To chord, you first need to have a number revealed on the board, and you must have correctly flagged all the mines adjacent to that number.

For example, if you have a '2' revealed and you have placed exactly two flags in the squares next to it, you can then click on the '2' itself. This action will automatically reveal all the remaining unflagged squares adjacent to the '2'. If your flags were correct, these newly revealed squares will be safe. If you made a mistake and an unflagged square was actually a mine, you will detonate it and lose the game.

Questions

How do I win a game of Minesweeper?

You win Minesweeper by successfully revealing all the squares that do not contain mines. Flagging all the mines correctly helps track your progress, but the primary goal is to uncover every safe square on the board without triggering a bomb.

What does 'chording' mean in Minesweeper gameplay?

Chording refers to an advanced move where you click on a revealed number that has the correct number of flags around it. For example, if a '3' has three flags adjacent to it, clicking the '3' will automatically clear all remaining unflagged adjacent squares, speeding up play if your flags are accurate.

Are the rules different for different board sizes?

No, the fundamental rules of Minesweeper remain consistent across all board sizes. Whether you play on the Beginner 9x9 board, Intermediate 16x16, or Expert 16x30, the mechanics of revealing squares, numbering adjacent mines, and flagging potential bombs are the same.
