Mines - The Rules
The game is also known under the name Minesweeper: a board contains certain bombs, that must be indicated by the player. You can find with a click the number of bombs found in the 8 neighbor squares; if a square is in a corner or on the board margin, then the number of neighbors could be smaller than 8.
In order to mark a square as having a bomb, you can right click it. Otherwise, left click it to find the number of bombs in the neighbor squares.
The game is over when all the squares, bombs excepted, are discovered. The game is lost when you left-click a bomb.
