Each edition of the Samurai Sudoku Puzzle series contains 60 computer-generated Samurai Sudoku with three levels of difficulty: easy, medium and hard . Samurai Sudoku puzzles are asymmetric Sudoku with different amounts of predefined numbers. Each Samurai Sudoku takes up a full page so that there is enough extra space within the box to write smaller, optional solutions as you work through the puzzle. All puzzles can be easily solved by excluding numbers by process of elimination from other columns, rows, or boxes, leaving only one possible solution . This book contains solutions for each of the 60 puzzles, as well as general game instructions for the Samurai Sudoku.
