Junpei finds an assortment of files within the different escape rooms in Zero Escape: Nine Hours, Nine Persons, Nine Doors. They are viewable under the "Files" button, but are not all viewable at the same time, as it is impossible for Junpei to visit all of the locations that contain files in one playthrough. Some of them are used as hints in order to solve some of the puzzles, while others are important key items found during the story and have nothing to do with the puzzles.

  • Add up all of the numbers involved.

  • Keep adding digits until you are left with a single digit number.
  • That number is the [digital root].
  • (Example: 6 + 7 + 8 = 21 -> 2 + 1 = [3])
  • (Example: 1 + 2 + 3 + 4 = 10 -> 1 + 0 = [1])
