*** Based on the famous queen's problem, you have to place 8 queens on the chessboard in such a way so that no one can attack another and try to do it in minimum number of moves.

*** Now combined with four (4) Knights interchange (swapping) puzzle.

*** You can select either 'Queen Mode' or 'Knight Mode' from options menu.

The following are the rules of the game:

#The green dots are the possible places where the queen can move.

#The black queen is your current position and white queens are the ones which are already explored.

#You can also undo by clicking on the undo button and the current queen will go away. Previous queen will be the current queen.

Hint button shows the possible moves remaining.

Clear button clears the chess board.
