The book Sudoku Difficult is another one in a series of Sudoku books and, in a sense, the crowning glory of the series. Of all the books in this series, this one contains the most difficult puzzles and presents the greatest challenge.
Sudoku Difficult is, as the name suggests, a book containing hard Sudoku puzzles. It is therefore not suitable for beginners, but is aimed at experienced players who also work with different Sudoku strategies.
Advanced and difficult strategies such as X-Wing, Forcing Chains, or XY Chains must be used to solve the puzzles in this book.
The book contains a total of 500 Sudoku puzzles. There are four puzzles on each page. You can order Sudoku Difficult for $9.99 (£7.99 / EUR 9.99 plus VAT) on Amazon*.
Details about the Sudoku Difficult book
The book contains:
- 500 Sudoku puzzles for experienced and skilled players
- With all solutions at the back of the book
- 4 Sudoku grids per page
- Book in A4 paper format
If you want to get an idea of the difficulty level of the Sudoku puzzles, you can download a sample page with four puzzles from the book on this page and print it out if you wish. This has the advantage that you can get an idea of whether the level of difficulty and the format (or size) are right for you before you buy. Of course, the level of the number puzzles also varies to a certain extent within such a book. However, the individual Sudoku puzzles are comparable to those in the linked file above.

The other books from this list are all at a simpler level than this one. However, the book on Sudoku strategies also contains lots of methods that are needed to solve these difficult puzzles.
