Minesweeper rules

Although the game is extremely simple to understand, here are the rules.

To begin a game, click on or type F2 (notice that you can also click on ' New' in the 'Game' menu).
The purpose of the game is to locate all the mines hidden under the board, without exploding, and to do it in a minimal time. Here is the point of Minesweeper!

You have to left click on squares to know what'd on it. Either it is a mine, and it explodes and you lost and you have to restart a game, either it's not a mine, and you have a number between and , which indicates the number of mines in the eight surrounding squares. When you identify a mine, you can (you don't have to in order to win) mark it with the right button: it's a flag

Here's the starting board on beginner

on the left, the mine counter, which decrements for each flag put. On the right, the timer, who's wrong because it starts at 1.00 second.
