SUDOKU COLLECTION

By James E. Riley. Traditional Sudoku number puzzles are solved using reasoning and logic—no math skills required! There are a number of strategies to employ in solving each unique puzzle, and each book begins with a thorough introduction and helpful tips for developing solving techniques. Sudoku Sums follow the same rules as the traditional puzzles, only now numbers must add up in groups to equal a given number. Wordoku is a variation using letters instead of numbers, with the additional challenge of discovering a hidden nine-letter word or phrase. Finally, Variety puzzles provide a little bit of all of the above. All books include answer keys. Good Year.gdypuzzles
