Well, it's pretty hard….I GUESS. Though, technically, shouldn't the world's hardest Sudoku just have a single '9' in one of the cubes and the rest of the grid is otherwise blank? Or some kind of specialty Jumanji-esque puzzle that unleashes a dragon every time you fill in a space? You laugh now, but in a world where Battleship and Stretch Armstrong are movies, it's only a matter of time before we see "Sudoku: The Movie," starring, oh, let's say Michael Keaton.
