Big Walk: How to Solve the Red and White Dome Microphone Puzzle

The red and white striped dome in Big Walk holds a co-op puzzle built entirely around sound. Inside you’ll find a chair with a headset, a red button console, and a semi-circle of microphone stands. The goal is to work out which single microphone is transmitting cleanly, then press the button tied to it. It sounds easy, but every microphone picks up your voice to some degree, so the seated player has to judge clarity rather than just whether they hear something.

Quick answer: Put one player in the chair with the headset and send the other to speak into each microphone in turn. When the seated player hears one mic come through crisp and close, they wave their arms, and the second player presses the yellow button on that stand to fill the meter and finish the puzzle.

What you need before starting

This puzzle cannot be solved alone. You need at least two players, one to sit and listen and one to move between the microphones. It sits inside the large red and white dome that overlooks the ocean, and it can be located on the map around the coordinates 34, 12.

The layout is fixed. A green chair with a headset hangs at the center, and several microphone stands are arranged in a semi-circle in front of it. Each stand has its own button. Only one microphone is active during each round, and the seated player is the only one who can tell which one it is.

Player roles

Role	What they do
Seated player	Sits in the chair, wears the headset, and listens for the microphone with the clearest signal.
Testing player	Walks to each microphone stand, speaks into it, waits for the arm-wave signal, then presses the correct button.

If you have more than two players, spread the extra people across the stands so each person covers one or two microphones. That speeds up testing and cuts down on running back and forth.

How to solve the microphone puzzle

Have one player sit in the chair and put on the headset. Wait until they confirm they can hear room audio before anyone starts speaking.

Send the testing player to the semi-circle of stands. There’s no set order, so pick one end and work across so no microphone gets skipped.

Speak the same short phrase into each mic, something like “test, test,” at the same volume and distance every time. Keeping it consistent lets the seated player compare each mic fairly.

The seated player listens for clarity, not loudness. The correct microphone sounds crisp and close, as if the speaker is right beside them, while every wrong mic sounds distant, muffled, or echoey.

Once the seated player is sure, they wave their arms to signal the live microphone. Big, obvious waves work best, since arm gestures are the only way to communicate the answer.

The testing player presses the yellow button on that stand. A correct answer adds progress to the meter in front of the chair.

Repeat the process for each round, always following the seated player’s judgment, until the meter is completely full.

How to know it worked

Each correct pick fills part of the green meter beside the chair. When it reaches full, confetti drops and the reward is released, which confirms the puzzle is complete. If nothing happens after a button press, you chose the wrong microphone. There’s no penalty and no reset, so simply go back to listening and try again.

Common mistakes to avoid

Mistake	Fix
Seated player signals on any audible sound	Wait for unmistakable, close-up clarity before waving.
Testing player speaks at different volumes per mic	Use the same phrase, volume, and distance at every stand.
Testing player decides the answer from their own end	They hear themselves through every mic, so always wait for the arm wave.
Both players rush through the stands	Test each mic two or three times so the clear one stands out.

Note: This is a separate challenge from the green chair with the low microphone found elsewhere in Big Walk. That one uses different mechanics, so don’t assume the same logic carries over. The red and white dome puzzle comes down to two things: the seated player’s patience and the testing player’s consistency. Trust the clarity rule over everything else, and it usually falls in a few minutes.
