Consider an empty 4x4 grid. You have to place a different 2 digit number in each square.
Here's the catch: they have to add up to the same number on the horizontal axis and the vertical axis and on the 2 diagonal segments that make an X across the grid.
Here's the bigger catch: flip the grid upside-down and the horizontals, verticals and diagonals all still have to add up to the same number.
