What you need to begin
You need: 1. A sudoku puzzle. I enlarged this one (which was the puzzle that appeared on Sudoku.com on July 8, 2006.) to make photography easier. I find this system work…
Fill in the "Missing Grid"
You see, a Sudoku puzzle is missing a grid. Once you put in this grid, it is sooo much easier. Enter the numbers 1 through 9 in a "tic-tac-toe" pattern in every blank b…

I know, they aren't really quadrants, but you know what I mean, don't you? If you've looked across the columns, and across the rows and there are all duplicates, then lo…
