100 Sudoku Windoku Puzzles 9×9 | Kindle Scribe | Learn to Solve Series | Digital Puzzle Book | Volume 1 | PDF for e-Readers | Brain teasers

A Sudoku Windoku has an extra constraint from classic sudoku. There are four 3×3 shaded squares that should contain the numbers 1 to 9 as well.

This book is the book #20, and part of the series “LEARN TO SOLVE”, series that will cover all the puzzles that exist in the world, and along the way new ones will also be developed.

Learn To Solve – Sudoku WINDOKU 100 consists of mixture of 9×9 puzzle grids with different difficulty, total of 100 different puzzles. Each puzzle is unique, and great care is taken to make sure they do not repeat in any of the other books.

Puzzle difficulty is progressively increasing, from super easy, medium, hard to extreme.

This way you can monitor your progress as you are learning to solve the puzzle, or if you are already familiarized with sudoku puzzles, this could be a challenging book to see where do you stand with puzzle solving, on what level will it become too hard for you?
