Code Number Sudoku is a unique, patent-pending version of Sudoku. Certain numbers in each puzzle are "coded" with a symbol. When you figure out the number for a square that contains a symbol, you have figured out the number for all squares carrying that same symbol. For example, in a sample puzzle, if you determine that a square with a star contains a 5, you know that all squares with stars in that puzzle grid will carry the number 5. It's that simple! And it's even more fun than traditional Sudoku!
