Each edition of the 1000 Hard Sudoku series contains 1000 computer-generated Sudoku puzzles. The Sudoku puzzles are asymmetric Sudoku with 32 predefined numbers from 1 to 9. This gives the level of difficulty as hard. 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, leaving only one possible solution. This book contains solutions as well as general game instructions for each of the 1000 puzzles.
