We make regular Sudoku puzzles and custom Sudoku puzzles for books, newspapers, magazines, organizations, even individuals. We turn coffee into puzzles. Today, I am going to show you how to play Sudoku. We will cover the rules of the game and some basic strategies you can use to solve Sudoku puzzles. I am going to go step by step and walk you through the entire solution to a Sudoku puzzle. Along the way we'll discuss the rules of Sudoku, whether or not you should guess when playing Sudoku and the techniques I call one choice, one place, scanning and double scanning. Then we'll use all these techniques to finish the puzzle together. Before we get started, you might want to print your own copy of the Sudoku puzzle we'll be working on today, or if you prefer, you can just follow along with the video. The Sudoku puzzle we'll be using is available for download and printing at I am an Associate Professor of Mathematics at James Madison University in Harrisonburg, Virginia and part of my research centers around the mathematics of games and puzzles. Now, put on your thinking cap and get out your pencils; it's time to play Sudoku.
