Available in PDF, EPUB and Kindle. Book excerpt: The hotter-than-hot puzzles, now in a format just for kids! Youngsters who want to start solving can have fun with these smaller sudokus that are right on their level. Instead of the usual sudoku grid, which goes from 1 to 9, most of these puzzles go only from 1 to 6. It's simpler, increases the chances for success, and minimizes frustration. At the same time, children are building their skills--and preparing themselves to work on the 22 regular-size versions that are found at the end of the book. An introduction teaches the basic sudoku rules and offers easy-to-follow hints on how to figure out which number goes where. "The new international craze!"--The New York Times "People are wild about it..."--Sherry Stern of the Los Angeles Times
