3. Eight Queens
In chess, a queen can go any number of spaces in a straight line vertically, horizontally, or diagonally. Can you fit 8 queens on a chessboard so none of them can attack any of the others? Try it on a real chessboard (or 8x8 grid) using pennies for queens. Want to start smaller? Try it with just 4 queens on a 4x4 board.
