Will Shortz Presents The Little Black Book of Sudoku: 400 Puzzles

Long recognized as a great "puzzler," not just for sudoku but for his NYTimes crosswords, Will Shortz provides 400 puzzles of difficulties ranging from "Light and Easy" to "Beware! Very Challenging!" Regardless of the level, these puzzles are scrupulously fair, requiring, in my experience, only two occasions of "trailing" (and those may have been my own fault), when most other such books often require the puzzler to use this "technique" many times during the book.

Will Shortz is a fabulous puzzle editor, and this collection is one of his best. The spine of the book is spiral, which fascilitates puzzle working. Extremely high quality paper makes it easy to erase notes or mistakes. I recommend this to anyone who enjoys sudoku. It has four levels of difficulty, 100 puzzles of each level.
