8 Queens (itch)

Try to place all 8 queens on the chessboard in this classic puzzle!

Eventually I aim to add levels, with each chessboard being one size larger than the next (except for 2 and 3, as there is no solution to those chessboards).

Press the arrow keys to change the board's colors, and click on the board to place or remove a queen. Circles appear in the places where queens cannot be placed.
