The short answer

The room holds empty tile slots. One player outside uses a telescope while their partner holds each tile up inside until its mark becomes visible; memorise the marks, carry the tiles out, shut the door, and recreate the sequence on the display panel.

The same family as the green tower's invisible ink: it puts looking and placing on opposite sides of glass.

Step-by-step4 steps

  1. 1

    Split it: one holds, one watches

    The room left of the scaffold house has a set of tiles and empty tile slots. One player holds tiles up inside while the other watches from outside through a telescope.

    Room A - can only lookScreen / disc / tile patternOnly he can see thisx Cannot see the buttons oppositeRoom B - can only act5 buttons (matching positions)x Cannot see room A's screenVoice is cutAll that is left: gestures - knocks on the partition - pointingAgree "which one from the left" first, then start transmitting
    Schematic: separated communication. One side can only look, the other can only act, and the channel between them is cut on purpose - orange barn, silent room, interrogation room and beach house all fit this model.
  2. 2

    Memorise the marks

    The marks on the tiles are invisible at rest and only appear when a tile is held up at the right angle. Memorise them one by one.

  3. 3

    Carry them out and shut the door

    Take the tiles outside and close the room door behind you.

  4. 4

    Recreate the sequence on the display panel

    On the display panel outside the room, rebuild the sequence in the order you memorised. Match it and it is done.

Where it goes wrong

These are the questions real players search for most. Working through them in order usually finds the cause.

Have the player inside change the height and angle they hold it at. The telescope's field of view is narrow, and it only works from the right position.

Split the memorising. One person takes the top half and one takes the bottom, which beats one person brute-forcing all nine.

After finishing:1 blue tower part.

Where this solution came from

games.gg's Chinese guide Color Tile and The GameSlayer's Invisible Ink describe the same thing - telescope, hold the tile up, recreate the sequence after shutting the door; bigwalk.tips records another instance of the same mechanic under the green tower entries.

Puzzles in this game are not assigned in a fixed order: most of them reward the same generic red gourd, so you can clear any set of challenges around a tower. That is why two guides list different puzzle line-ups for the same tower — neither is wrong. Unless a coordinate is credited to a named source it is a community measurement, and later versions can shift it; once you are in the area, trust the landmark over the number.
