Riddle of the Sphinx Hints

Where is the code for Gatenbrink's door?

  • 1 of 6: For a clue, go back from the Queen's Chamber towards the outside, until you reach the junction with the ladders.
  • 2 of 6: Examine the floor to the sides of the passage.
  • 3 of 6: There is a small grate in the floor.
  • 4 of 6: Open the grate and look inside carefully.
  • 5 of 6: Taped to the right side of the opening is a note.
  • 6 of 6: The note says the code can be figured out by adding the last four digits of Gil's campus ID number and the date the Sphinx scaffolding was constructed.
