Everyone loves sudoku puzzles, finding them impossible to put down. The only problem: having enough sudokus to solve!

   Created in the United States, these addictive conundrums were originally called “Number Place” puzzles until their recent rise in popularity in Japan, where the name translated as sudoku. However, in a true sudoku, unlike a “Number Place” puzzle, the grids are symmetrical. This trait makes for a more elegant solve. Every puzzle included inside is symmetrical, which is not always the case in other sudoku books.

   In this “Martial Arts Sudoku” series, we’ve indicated the skill level necessary to complete each book in the same way Japanese karate levels are ranked: by different colored belts. This is the Second-Degree Black Belt volume, filled with puzzles that will provide a sly, absorbing test for even the best, most proficient experts.

   You’ll go crazy for these super engaging brain bafflers!

I am a confessed Sudoku addict. I have been looking for a book that
doesn't have any easy or medium puzzles, but all hards ones. I was very
happy to come across this one at Barnes and Noble and bought it for myself as a Christmas gift. This book will not disappoint if you are lookoing for a challenge.

Beware! This book mostly has very difficult puzzles that require knowledge of advanced strategies to solve such as X Wing, Unique Rectangles, XYZ Wing, XY Wing, Swordfish, etc. I love it as I do all of Frank Longo's advanced books. If you're looking for a challenge, this book will meet your expectations.

I found this book to be very challenging but not impossible. There were a few puzzles that I had to look up the answer, otherwise, I would have guessed. I really enjoyed doing these.

White rather than newsprint makes for easier working
