Divide the two roles
What to know
The listener remains at the green speaker chair and identifies the music. The explorer travels toward the Green area, finds the light-blue station with matching music and locates the hidden box.
02 · Steps
Open the remote box
What to know
Once the explorer is in position, communicate through in-game voice or a walkie-talkie. The listener presses the chair-side button, opening the distant box so the explorer can take the red reward.
- Leave one player at the speaker chair
- Send another player to the matching Radio Station
- Confirm the music match
- Stand beside the hidden box
- Signal the listener to press the button
- Collect the reward while the box is open

Do not mix up the microphone puzzle
What to know
This is not the Five Microphone Puzzle, where multiple players speak and a listener chooses between voices. Those mechanics belong to a separate challenge.

What this guide does not claim
Community labels are not presented as official names. Approximate coordinates stay marked as approximate, version-sensitive facts need a publication-day check, and no unsupported platform, code, solo route or mod-only shortcut is invented.

Frequently asked questions
What is the direct answer?
Use at least two players. One listens at the green speaker chair while another finds the matching light-blue Radio Station and hidden box, then signals the listener to press the button.
How current is this information?
This page and its named source trail were reviewed on September 4, 2026. Platform, version and live-service details can still change after that date.
Are community puzzle names official?
Not necessarily. Big Walk does not provide an official name for every challenge, so this site identifies player-made labels whenever that distinction matters.
