Wordoku (also known as Letter Sudoku) is played the same way as the standard Sudoku puzzle except that the letters A through I are used rather than the digits 1 through 9. If you enjoy Sudoku puzzles then this might be the book for you. It's a little different but just as much fun and every bit as challenging, perhaps more so until you get familiar with it. This edition contains 150 of the 9x9 grid version with other sizes also available.
