This is a good book on Sudoku for kids. The book includes 77 puzzles. The puzzles are of two sizes: 6x6, and 9x9. The solutions are at the end of the book. There are no categrories or levels of difficulty for the puzzles.
The first three pages in this book are dedicated for strategy, hints, rules, or tips. All the puzzles in the book are Classic Sudoku (with numbers). There are no Alphabet Sudoku (with letters) or Symbol Sudoku (with shapes and symbols) like the two books "Kindergarten Sudoku" and "Super Sudoku for Kids". Also, there are no simple 4x4 puzzles like some of the other books.
