The Eight Queens Problem

1 - 8 9 - 16 17 - 24 25 - 32 33 - 40 41 - 48 49 - 56 57 - 64	Mark 8 checkboxes as if they were queens on a chessboard. The idea is to place them on the board so that they cannot 'take' each other. For non-chessplayers: make sure there is no more than one queen in a line, horizontally, vertically or diagonally. Then press the check button to see if you have done it correctly.
