The Eight Queens

Cease the war of The Eight Queens on the chessboard!

Can you bring peace to the chessboard by placing eight queens onto the board but prevent them from capturing each other? In this game you will be given a standard chessboard, and the 8 queens will be placed on the right of the board. According to the rules of chess, a queen can capture another piece on the same line in vertical, horizontal or diagonal direction. You can click and drag the pieces and place them onto the board, but note that they cannot be removed after settling. A queen cannot be placed if it is on a capturing line of another queen on the board. The number of queens you have put and the amount of time spent are recorded on the left of the screen. When no more moves can be made, the game ends. Conquer the queens and win their allegiance!
