Become a master in solving classic Sudoku 9x9. After solving all the puzzles in this book, you will be a Sudoku Pro. You start with easy Sudoku puzzles and you gradually build your way up to extremely hard Sudoku puzzles.
The goal of Sudoku is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 to 9 exactly once.
Classic Sudoku 9x9 - Easy to Extreme is a collection of 276 puzzles:
- 54 easy Sudoku 9x9 puzzles
- 54 medium Sudoku 9x9 puzzles
- 54 hard Sudoku 9x9 puzzles
- 54 extreme Sudoku 9x9 puzzles
- 60 extra logic puzzles
I guarantee that every logic puzzle in this Sudoku puzzle book has been carefully checked to ensure that each puzzle has only 1 solution.
None of the puzzles in this book will appear in any of the other PuzzleBooks.net books.
Sudoku is also known as Number Place, Nanpure, Su Doku. Quite often Sudoku is misspelled as Suduko, Soduko, Sodoku, Sudoko, Suduku and Soduku.
This book seems to me to be very complete. It contains many sudoku puzzles with different levels of difficulty but it also contains other different puzzles. Before each type of puzzle we can find a good explanation with instructions for resolving them.
However, I have not resolved the puzzles because I received the e-book in pdf format :(
