Players can move the wheels in the corners of the board to reveal secret passages, to show which doors may or may not be available to use, or the Dark Mark may appear. In this Harry Potter Edition of the Clue game, a student has vanished from the Hogwarts School of Witchcraft and Wizardry. Who can solve the mysterious disappearance? Kids play as Harry, Ron, Hermione, Ginny, Luna, or Neville, and try to discover who did it, what spell or item was used, and where the attack happened.
