Product Description

Sudoku is the number-placing puzzle that is spreading across the world, engaging the minds of people of all ages. The rules are simple, you don't need to know any mathematics, all you need is logic. Samurai Sudoku puzzles are like traditional Sudoku puzzles but with five interlocking Sudoku grids. This book contains 100 of these massive puzzles, including solutions. All the Samurai Sudoku puzzles in this book are symmetric. The rule is the same: Each row, column and 3x3 box in each puzzle grid must contain the numbers 1-9 only once. All puzzles in this book are hard, however the puzzles get progressively harder and the puzzles at the end may be considered very hard. This book is for those who feel ordinary Sudoku puzzles are too easy or too quick to solve and want more challenging puzzles. These puzzles can take hours to solve and if you solve two of these every week this book will last you a year! Have fun!

Fun, but could have been more challenging
I enjoyed this collection of puzzles. I don't think the puzzles are as hard as the author claims, "all the puzzles in this book are hard" maybe 20% are more involved; it is true that the last third of the puzzles are more difficult than the fist third, but it took me only 30 minutes to do puzzle number 100.

On the plus side, the author managed to avoid all of those annoying "choose a number and see what happens" tricks that some sudoku books are full of. A number of the puzzles had some very interesting logic sequences which were fun.

The secret to Samurai Sudoku is the central puzzle; solve it and the puzzle reduces to 4 independent sudoku puzzles. I believe that in most cases, once the central puzzle was solved, the remaining puzzles were much too easy. The author typically puts 30+ clues in the outer puzzles. I really think they should have been reduced to lower 20 or high teens.

Nonetheless, I consider this a book worth purchasing, it took me just under two months to finish the book in off hours and at bedtime, and how can you go wrong with two months of fun for only $9.99.

As good as the first book!
Like the first volume, Peter Greene's 2nd book of samurai sudoku puzzles is great fun! The puzzle are symmetrical and pleasing to the senses. The page size is comfortable for working the large puzzles and the paper is a good for the inevitable erasures. Very few of the puzzles leave you with several sets of pairs, which result in having to guess and check.

Mr. Greene says if you do two puzzles a week, the book will last almost a year. Well, who can be limited to two a week? Maybe I'm just getting better at doing these puzzles, but I got through the whole book in a couple or three months.

My favourite puzzles
I really like these bigger Sudoku puzzles, since the regular ones are a little too quick to solve. This book has enough puzzles to last you a looong time. The first book was great and this one looks like it's keeping up the same quality! Very good!
