Sudoku Puzzle Book for Adults: 1000+ Hard Sudoku Puzzles with Solutions - Vol. 2

The Sudoku Puzzle Book for Adults: 1000+ Hard Sudoku Puzzles with Solutions - Vol. 2 offers a collection of challenging Sudoku puzzles for experienced solvers. The book follows the success of Volume 1, which was well-received by puzzle enthusiasts. One standout feature of this book is the difficulty level. Unlike other Sudoku puzzle books that include easy and medium puzzles, this volume focuses solely on hard puzzles, making it suitable for those who want a real challenge. The puzzles in this book require advanced techniques, such as x-wings, y-wings, and empty rectangles, which adds another layer of complexity for experienced solvers. However, some customers have mentioned that they did not find the puzzles as difficult as expected. While they agreed that the puzzles were challenging, they felt that the format of the book hindered their experience. The puzzles are quite small and cramped, with 12 puzzles per page, leaving no space to make notes. This can be frustrating for solvers who rely on note-taking as part of their solving strategy. Some customers also commented that the solution grids were the same size as the puzzles, making the book unnecessarily heavy and bulky. Despite these drawbacks, the book still offers great value for money, with over 1000 puzzles to keep solvers busy for a long time. It is recommended for those who are relatively new to Sudoku and want to tackle harder puzzles than what is typically found in newspapers. However, experienced solvers may find these puzzles to be quick and easy, suitable for solving in short intervals. In conclusion, the Sudoku Puzzle Book for Adults: 1000+ Hard Sudoku Puzzles with Solutions - Vol. 2 is a decent collection of challenging puzzles, especially for those who are new to Sudoku or enjoy quick puzzles. However, the format and size of the book may not be ideal for those who prefer larger puzzles with space for note-taking.
