Indiana Jones and The Last Crusade Hints

How do I open the door in the room with the six skulls?

  • 1 of 6: You haven't read the diary, have you?
  • 2 of 6: Try pushing the skulls.
  • 3 of 6: Notice that the skulls act as some kind of instrument?
  • 4 of 6: The musical manuscript in the diary tells you which notes to play.
  • 5 of 6: A note on the top line indicates the leftmost skull.
  • 6 of 6: A note on the second line indicates the second skull from the left, etc.
