Minesweeper is a classic puzzle game where you uncover squares on a grid while avoiding hidden mines. The goal is to reveal every safe square without detonating a single mine.

Click a square to reveal it. If it contains a mine, the game is over. If it's safe, it shows a number indicating how many of its eight neighboring squares contain mines. A blank square (zero adjacent mines) automatically reveals its neighbors.

Use the numbers as clues to deduce where the mines are. For example, if a square shows "1" and only one adjacent square is still hidden, that hidden square must be a mine. Right-click or long-press to flag squares you believe contain mines — this helps you keep track.

Start by clicking near the center of the board for a better opening. Work outward from revealed numbers, using logic to identify safe squares and mines. This free online version features a clean interface and works on both desktop and mobile.
