The EIGHT QUEENS Puzzle!


A chess queen can move in any straight line horizontally, vertically or diagonally. Click any square on the board to see where the queen can go.

Here's the problem:

Can you put EIGHT queens on the board so that none of them can go and attack another one?

This classic puzzle was invented by the brilliant SAM LOYD and he claimed he knew 12 different answers! He also said there was only one answer where no three queens were in an exact straight line at any angle and that's the perfect solution that we've given you. But can you find the other 11?
