100 Samurai Sudoku Puzzles 2

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!
