Are you guys related to Walter Mackey?Gee, that's a good question, whoever you are that didn't ask it. For the uninitiated, Walter Mackey is the name of the gentleman who concocts those "Super Sudoku" puzzles for Dell's Sudoku magazines. They're the devils where you have a 16x16 grid and need to not repeat a number in any row, column, 4x4 box or (and this is the killer) long diagonal.
As far as we know, Walter Mackey is not related to the Puzzle Brothers. Nor is there a Walter Mackey in our family who gets confused for the creator of those s.o.b. Super Sudokus.
Thank you for not writing! More soon, so keep it here, dear!
