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. The puzzles start with a few easy ones for warming up, but the majority of the puzzles are hard and can take hours to solve.
This book is for those who feel ordinary Sudoku puzzles are too easy or too quick to solve and want more challenging puzzles. If you solve two of these every week this book will last you a year!
