All the starting numbers have been stripped away, leaving you with something truly intriguing: Naked Sudoku. Each puzzle is a variation on regular sudoku, but there are no starting numbers to help. Instead, you must use other types of clues to determine where to begin. In one variant, for instance, greater-than and less-than signs point out the way. These are sudoku puzzles that will push your brain to the limit and expose your true sudoku talent.
