A Sudoku puzzle variation called Samurai Sudoku consists of 5 overlapping Sudoku sub-puzzles. In this book you get 150 Hard Samurai Sudoku.
Puzzles consist of five overlapping Sudoku grids and follow the same rules as Sudoku in that every row, column, and block of each of the five grids must contain the numbers "1" to "9". Where the grids overlap, the rows and columns do not go beyond their usual length but the interlocking blocks give you more clues. Samurai puzzles provide five times the challenge, fun and satisfactionRelated Subjects
