Suppose you have 19 hexagons arranged in roughly a 3x3x3 hexagon (so there is a center hexagon, surrounded by 6, surrounded by 12, just like in Settlers of Catan). Place the numbers 1 through 19 into these 19 hexes (once each) so that the sum along any diagonal is the same. Note that in each of the three directions, there are two 3-hex diagonals, two 4-hex diagonals and one 5-hex diagonal.
