Introduction

Minesweeper is a classic deduction game where you reveal safe cells while avoiding hidden mines. Numbered cells show how many mines touch that square, so every safe move comes from reading patterns, marking certain mines, and expanding open space without guessing too early.

How to Play

Open a cell to begin. The first move is safe, and empty areas expand automatically. Use flag mode or right click to mark cells you believe contain mines. Read the numbers around opened cells, compare them with your flags, and reveal every non-mine cell to clear the board.

Reading the Numbers

Each number tells you how many mines are touching that opened cell, including diagonals. If a 1 touches only one hidden cell, that hidden cell must be a mine. If all mines around a number are already flagged, the remaining neighboring hidden cells are safe.

Why the First Click Is Safe

A frustrating first-click loss does not teach anything, so this version creates the minefield after your first move and keeps that starting cell and its neighbors safe. You still need logic after the opening, but the game begins with useful information instead of chance.

Better Minesweeper Strategy

Work from open edges, not isolated guesses. Compare neighboring numbers to find shared hidden cells. When a number is fully satisfied by flags, use it to expand safe areas. Save uncertain guesses for the end of a board, when there are fewer unknown cells.

Difficulty and Replay Value

Beginner boards are good for learning patterns. Intermediate boards require more careful flagging. Expert boards have denser mine placement, so progress depends on disciplined deduction and avoiding unnecessary flags.

Frequently Asked Questions

What do the numbers mean in Minesweeper?

A number shows how many mines are touching that cell horizontally, vertically, or diagonally.

Can the first click hit a mine?

No. This version generates a safe starting area after your first click, so the opening move will not lose the game.

How do I place a flag?

Use flag mode on touch devices, or right click a hidden cell on desktop. Flags help track cells that you believe contain mines.

How do I win Minesweeper?

Reveal every cell that does not contain a mine. You do not need to flag every mine, but accurate flags make solving easier.

Is Minesweeper mostly luck?

Many boards can be solved mostly by logic. Some late-board positions may require probability, but careful number comparison reduces guessing.
