Where to go
The puzzle is a dark performance structure south of Yellow Tower, around 3410, 1590. One side contains the lit booth or stage cue, while the opposite audience side has seven controls.
Number the seven audience controls, reverse the booth view horizontally, and press one confirmed position at a time.
At the dark stage south of Yellow Tower around 3410, 1590, put one player in the lit booth and one beside the seven audience buttons. Number the audience row 1-7 from the button player’s left. The booth view is horizontally mirrored, so convert positions as 1↔7, 2↔6, 3↔5, and 4↔4. The booth player signals the converted number with slow arm raises; the audience player repeats it, presses once, and waits for the next light. Never use the raw booth position without mirroring it.
The puzzle is a dark performance structure south of Yellow Tower, around 3410, 1590. One side contains the lit booth or stage cue, while the opposite audience side has seven controls.

Go south of Yellow Tower and confirm a lit booth opposite seven audience controls.
The central control has three mirrored pairs on either side.

From the operator viewpoint, label leftmost 1, centre 4, and rightmost 7.
Both players can repeat the same direction and centre number.

Write down 1↔7, 2↔6, 3↔5, and 4↔4 before the reader is isolated.
Every raw booth position has one converted audience answer.

The booth player identifies the current light, converts it horizontally, and signals only that converted number.
No raw unconverted number is announced.

The operator repeats the number, points at the control, presses once, and waits for visible progression.
The next cue appears or the stage confirms the input.

Repeat read, mirror, confirm, press. If rejected, stop and restart from the first newly lit position.
The reward releases only after the current full sequence is accepted.
Use one player for each information or action side. The booth reader converts; the audience operator presses.
Keep the two core roles unchanged. Extra players should spot, carry, or record the current sequence without creating a second caller.
