Sudoku Basics
Sudoku (or su doku) is a game of numbers -- specifically, the numbers 1 through 9 -- but it really isn't about math. It's about logic.
Instead of 1 through 9, you could use the first nine letters of the alphabet or a set of nine symbols, and it would be the same game.
The basis of sudoku is a nine-by-nine grid. You've got three sections to think about: rows, columns and boxes.
