Arrange the queens


Queens can move horizontally, vertically and diagonally any number of spaces as illustrated. One piece ‘attacks’ another if it moves to the same tile that the other piece is on. How can you arrange eight queens on the board so they cannot attack each other?

    These are the two possible solutions.
    This is usually solved with guesswork and checks, although using logic may be faster. We know that each queen must be in it’s own row vertically and horizontally. We also know that 4 of the queens must be on white and 4 on black. This is true as because with 4 queens on the same color all of the rest of that colored squares are vulnerable to be attacked. (It could be done with maths.)
