Where to go
From Red Tower, look across the surrounding island for the separate green building with a glass-walled room, a long light meter, four reachable exterior buttons, and one raised exterior button beside a rock.

BIG WALK Glass Room Triangles: Relay the Current 1–5 Button Order
Number the four lower controls from left to right and call the raised control 5, then relay each triangle that lights inside the glass room.
Direct solution
At the green glass building, number the four lower outside buttons 1–4 from left to right and call the raised button 5. Put one player inside and close the door. The inside player watches which triangle lights, calls only that number, and waits; the outside player presses the matching button once. Repeat for every new light until the progress wall fills and confetti releases the red blob. The source run shows 3, 4, 2, 1, 5, but that is a worked run—not a code to enter blindly. Use the rock to reach button 5, then carry the blob back to Red Tower’s third receiver.
Before closing the door
- Bring at least two players: one signal reader inside and one button operator outside.
- Agree that the four lower controls are 1–4 from left to right and the high control is 5.
- Keep a walkie-talkie or voice connection active; if audio fails, agree on finger numbers before separating.
Exact steps
Source time 07:23Temporary frame 1Reach the separate green glass building
Leave Red Tower and travel to the green building that contains the visible red blob and glass-walled triangle puzzle.
You can see the long dot meter outside and the enclosed signaling room inside the green structure.
Source time 08:03Temporary frame 2Name the outside controls 1 through 5
Facing the controls, number the four lower buttons 1, 2, 3, 4 from left to right. Call the separate raised button 5. Both players must use this same map.
The operator can point to any called number immediately without asking left or right.
Source time 08:12Temporary frame 3Close one reader inside and watch the glow
The reader enters using the door button and closes the glass door. Watch the five triangle positions and report only the position that is currently glowing.
One triangle is lit for the reader while the outside operator remains beside the numbered controls.
Source time 08:22Temporary frame 4Call one number and press it once
The reader says a single number, then waits. The operator presses that matching exterior button once and confirms the progress meter moved before asking for the next signal.
The long wall meter gains progress and a new triangle becomes the active instruction.
Source time 08:42Temporary frame 5Use the rock when the signal is 5
When the top triangle indicates button 5, climb the nearby rock, jump toward the raised control, and interact at the top of the jump. Continue until the meter is full.
The high input registers, the meter completes, and confetti marks the solved puzzle.
Source time 09:02Temporary frame 6Collect the released third red blob
Take the red blob after the confetti. Attach it to a teammate’s backpack if you want both hands free for the return trip.
The blob is out of its enclosure and either held or secured on a player backpack.
Source time 09:31Temporary frame 7Insert it into Red Tower receiver 3
Return to the top of Red Tower. One player holds the third red receiver button while the carrier removes the blob and inserts it into the third container.
The third blob stays seated in its Red Tower container after the button is released.
Player-count plan
2 players
Use one reader and one operator. The operator repeats every number before pressing so a broken voice transmission does not create a wrong input.
3-4 players
Keep only one reader and one final operator. Extra players can stand by button 5 or watch the meter, but should not press unless the operator explicitly hands off that number.
Common mistakes
- Entering the source video’s example 3, 4, 2, 1, 5 without reading the current glowing triangles.
- Numbering the lower buttons from opposite directions inside and outside.
- Pressing several guessed controls before confirming that the meter moved.
- Calling the raised control “top” sometimes and “5” at other times, which creates duplicate vocabulary.
How to recover
- 1.Stop pressing, let the signal settle, and restate the shared map: lower left-to-right is 1–4, raised is 5.
- 2.Have the reader call one number and the operator repeat it back before every retry press.
- 3.If voice fails, the reader shows 1–4 fingers for the lower controls or points upward for 5; the operator points at the intended button and waits for a nod.
