Big Walk Interrogation Puzzle
A concise reader-and-placer guide for the cliffside one-way-glass puzzle.
Table of contents
Quick answer: split the group across the one-way glass, use the red light as part of the communication channel, and relay which symbols belong in which positions.
Find the cliffside room
The green puzzle building is set into the side of a cliff. Confirm Interrogation Puzzle under the Puzzles filter on the interactive map before sending anyone inside.

Relay every symbol placement
- Assign a reader and a placer before the room divides the group.
- Agree on position numbers and a small vocabulary for the symbol shapes.
- Move the players to opposite sides of the one-way glass.
- Use the red light when the room requires a visual signal between sides.
- The reader calls one symbol and its destination at a time.
- The placer repeats the call, makes the placement, and waits for confirmation before moving to the next symbol.
The recorded reward is a Red Blob. Read the current symbol layout; do not use a screenshot as a universal answer.
If a placement is rejected
Start with the first disputed position and verify the reading direction on both sides of the one-way glass. Test the red-light signal again. If another target is active in the selected world, complete the visible room state rather than assuming a fixed count.
