If you're already familiar with the classic sudoku puzzles and enjoy working them, you'll love solving our clever variation! Each puzzle has two extra types of clues - sums and "twins" - to help you figure out which numbers are missing. There's a comprehensive, step-by-step tutorial at the beginning of the book to teach you all the tricks and tips you'll need to start solving. The 75 puzzles range from easy to challenging, and there's a handy guide in the back to simplify the solving process.

The kind of logic used in these puzzles is the same as for regular sudoku, but with more kinds of clues, fewer starting numbers are needed. These puzzles are great for ages 10 and up - or for younger kids who already have a good grasp of logic.

This listing is for ONE book. Please convo me for larger quantities - price breaks are available!

(Note: Although the books were professionally printed, all other aspects of this book, including every puzzle, the layout, cover design, artwork, publishing, etc., were all created by the authors, and have been deemed handmade by Etsy.)
