Werner Miller's Magic Square Puzzle #4

Published on Sunday, June 06, 2010 in , , , ,

Werner Miller photographIt's Sunday, and that means it's time for the last of Werner Miller's devious magic square puzzles!

I'd like to thank Werner Miller publicly for very generously devising these puzzles, and letting me share them with you. Next Sunday, Grey Matters will return to its regular blog posts, and the answer to this puzzle will appear at the end.

For those who are new, here are the basic rules of the puzzle:

You're given the same set of 4 starting numbers grouped together in similar locations in a 3 by 3, 4 by 4, and 5 by 5 grids. The object is to fill out the grids with other numbers in such a way that the following conditions are satisfied when the grid is completed:

1) Only positive whole numbers are used.

2) No number is duplicated in a single grid (the same number may be used once in each of the 3 grids, however).

3) Each row, each column, and both diagonals of a single grid must total the same sum. All 3 grids in a puzzle, however, are not required to have the same sum (and usually won't). In other words, each grid must be a magic square, but all 3 grids do not have to have the same magic square total.

4) Puzzles will be posted here each Sunday, with the answers to a given puzzle being made available the following Sunday.

The solution to the 3X3 grid is incorrect. Rightmost column sum is 47, which is inconsistent with the other rows, columns, and diagonals that total 48.
