Rama Hints

How do I open the tetrahedron?

  • 1 of 4: There is an indentation on the wall next to the tetrahedron.
  • 2 of 4: It's shaped like the tuning forks that you've been finding in the corridors of New York.
  • 3 of 4: Try using them in the indentation.
  • 4 of 4: The one with 1 colored mark on it will cause a biot to exit from the tetrahedron.  There's no way to enter the tetrahedron, but watch the biot to get a hint for another puzzle.
