Put one player in the soundproof room, match their five current poses to the nine handled pose pieces, and submit the row without losing its order.
Go to the red-and-green split building around 3250, 1940. Put one performer in the right soundproof room and leave one builder with the nine pose pieces. Lock the room and start the puzzle. The performer reads the five current actions from left to right, stands by the viewing window, and acts out one pose at a time, returning to neutral between poses. The builder numbers the nine candidate pieces, records the matching piece for answer positions 1-5, places those five pieces in the same order, checks the row once, and submits it. If a pose is rejected, repeat only that position with a larger arm or body angle; the five-pose target stays the same for the retry. A correct row releases the red Blue Tower control-panel piece.
Travel to approximately 3250, 1940 on the lower Blue Tower route. The correct landmark is a red-and-green split building with two enclosed rooms, a central activation control, a viewing surface, nine loose tiles marked with body poses, and an outside reward pedestal. A room showing ordinary abstract symbols is a different locked-room puzzle.
Meet at the two-room structure around 3250, 1940. Confirm that its handled pieces show standing, crouching, and arm-position silhouettes rather than abstract icons.
You can see the two rooms, viewing surface, central control, nine pose pieces, and reward pedestal in the same small area.
Send the performer into the right soundproof room. The builder stays outside with the nine handled pose pieces and must be able to see the performer through the viewing surface.
The performer is inside the target room and the builder has an unobstructed view plus access to every candidate piece.
Arrange the nine pieces in a stable 3-by-3 reading order and label them 1-9, top-left to bottom-right. Take one reference image if the pieces are scattered. Also write five empty answer slots: 1, 2, 3, 4, 5.
The builder can name any candidate by one number and has not moved a piece into the answer row yet.
Use the central control to lock and start the room. Wait until the performer can see the first pose prompt and the outside controls are active before interpreting anything.
The room is active, the performer has a visible target, and the builder can still see them at the window.
Starting at the leftmost target, the performer stands close to the viewing surface and holds the exact arm height, side, and standing or crouching state. Hold for two clear beats, return to neutral, then show the next target. Repeat through position 5 without changing the order.
The builder has observed five separate poses and can identify the neutral boundary between every pair.
For each answer position, write the candidate number before touching a tile. Read the recorded sequence back as five short pose descriptions, then place the matching pieces into slots 1-5 in that exact order. Treat the performer's left and right as authoritative so the view is not mirrored accidentally.
All five slots are filled, and each physical piece matches the written candidate number for the same position.
If two pieces look similar or the room rejects the row, keep the recorded order and point to the disputed answer position through the window. The performer repeats only that target with a larger arm angle or a deeper crouch, using neutral before and after. Replace only the proven wrong piece; the target remains static across the retry.
The builder can state exactly which one of the two candidates matches the exaggerated pose before resubmitting.
Run one final left-to-right check, activate the submission control, and wait for the success state. Collect the released red control-panel piece before the group leaves for Blue Tower.
The row is accepted, the room exits its active state, and the team has the red Blue Tower piece.
Use one performer in the right room and one builder outside. The builder operates the start, keeps the written five-position record, and handles every piece.
Keep only one performer and one piece-handler. Extra players can call out candidate numbers or watch arm-side details, but one builder owns the final sequence so the row is not reordered.
