Sudoku: 200 Mixed (Easy, Medium, Hard) 9x9 Sudoku, Vol. 2

Each edition of the 200 Mixed Sudoku series contains 200 computer-generated Sudoku puzzles in three levels of difficulty: easy, medium and hard. Sudoku puzzles are asymmetric Sudoku with a variety of predefined numbers. There are four puzzles per page whereby each number square in a Sudoku provides enough extra space within the square 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, and have only one possible solution at a time. This book contains solutions as well as general game instructions for each of the 200 puzzles.
