1 means 1 There is a mine at the top, bottom, left and right, and at the oblique angle, advancing in turn, 2 to 2, 3 to 3. If you light a flag that is really a bomb in the square, it will be safe. If a flag that is not a bomb is lit in the square, it will be killed in the back. The question mark is three. I'm not sure if there is a bomb here. There will be no manslaughter. There is a trick. At the same time, click the left and right beside the number to clear the mine.

The first point must not be ray, haha.

Click the left button to open it, and right click to mark the thunder with a flag. At the same time, the numbers of the left and right key points can judge whether the surrounding mines are marked.

Each number represents nine squares around this number, and there are several thunder! For example, 1, there is only one thunder in nine surrounding cells, two thunder in nine surrounding cells, and so on.

You can dig this box by clicking. If you dig a mine, you lose.

If a number appears on the square, it means how many mines are in the eight squares around it.

To mark a square where you think there may be mines, right-click it.

The game area includes minefields, mine counters and timers.

The number is the thunder of eight squares around this square. The question mark was put up by myself. You can put a question mark where you can. The flag is to ensure that there is thunder.
