    Building 64 · remember the lights

    Face the room using the generator, ICR-7 island and Docks exit below. Tap the panel that flashes. Each round has a new sequence, and the same panel can flash more than once.

    Changing rounds clears this sequence. Undo restores it.

    Your sequence

    0 / 1 flashes recorded. Tap the next flashing panel.

    Your first flash will appear here. Record what you see; the helper does not detect the game screen.

    Find a panel in the room · photo references
    Panel A: Punchcard corner. Compare the real machine and nearby landmarks.

    The photographs show real panels; the schematic keeps their relative positions. Match landmarks when approaching from another doorway.
