Office Secret Phone Number

Answer. Use the telescope on the advertisement beside the Office subway bench to read 277-5944. Dial it on the in-game desk phone, then wait behind the lowest stairs in the three-level vending room for about one minute. Put on the headset and finish seven boards.

I am repeating a number that several guides print. It belongs to a game computer. Do not call it on a real phone. The chain is one of the three Stay secrets for Ending C.

  1. Telescope. Look at the advertisement beside the subway bench with the telescope.
  2. Desk phone. Dial 277-5944 on the fictional Office desk phone. The Morse message means Behind the stairs 1 minute.
  3. Stairs. Stand behind the lowest stairs in the three-floor vending machine room and wait about a minute.
  4. Boards. Put on the headset and solve seven boards. The linked player guide shows each layout; click the smiley face for the final square on the last board.

Ending C link

This is the Office third of Stay. Timesville uses 18 fish, Fish Paper, the Lost Key and a window-mode lock; Misery Town uses the projector remote and mime-room map. The regular waterfall keypad is not the Timesville secret.

The Behind Stairs guide translates the Morse hint as Behind the stairs 1 minute. Complete all seven boards after putting on the headset; on the last board, click the smiley face to reveal the final square. The source contains screenshots of each board.

Questions I keep seeing

Can I dial 277-5944?

Only on the fictional Office desk phone. Do not dial it on a real phone.
