Eight Queens Puzzle (v. 1.0) Разработано F. Permadi

Place 8 queens on the chess board in such a way so that no queen can attack each other.  Click on an empty square to put a queen. If you change your mind, you can click on the square again to remove the queen. If you see yellow squares, then two or more of your queens are fighting each other.
