There are a total of eight numbers that we need to distribute. Cells "C" and "F" each have 6 adjacent cells. That means that whatever numbers we assign to these two cells, they will be surrounded by all the remaining numbers except for one. That means we cannot place a number in these cells if it has two neighboring numbers among the set. Thus, "C" and "F" must be populated by 1 and 8, since these numbers only have one neighbor. Once we do this, the rest becomes fairly easy, yielding the final result: A : 7 B : 3 C : 1 D : 4 E : 5 F : 8 G : 6 H : 2 Note that this can be "reflected" either horizontally, or vertically or both and the solution will still be valid, since such transformations do not alter adjacency.
