Big Walk Multi-Light Puzzle
A two-building communication route for reading and pressing the lights in order.
Table of contents
Quick answer: this is a two-station communication puzzle, not a single building. Put one player in each waterside structure, agree how you will name the lights, then use the intercom and red-light channel to relay the sequence shown by the current attempt.
Understand the puzzle before pressing anything
The two players do not begin with the same information. One station supplies a light sequence and the other side must act on that information. The intercom and red light are part of the communication route; neither is a fixed answer.
The useful rule is describe, repeat, then press. Random inputs make it hard to tell whether the error was a bad callout, a reversed layout, or the wrong step in the sequence.
Find both buildings
The pair sits on a ledge over the water. Open the interactive map, enable Puzzles, and select Multi-Light Puzzle. Finding the rounded structure below is only half of the location check.

The second station is a separate, flatter building in the same puzzle pair. Move one player to each structure before beginning.

Assign the two stations
Use two simple role names. They are callouts for your group, not labels shown by the game.
- Reader: watches the current sequence and reports one step at a time.
- Operator: identifies the matching control, repeats the call, and makes the input only after both players agree.
If extra friends are present, keep one beside each primary player as a checker. Do not let several people call different lights over the intercom at once.
Agree on a light language
Before the first real input, freeze both players' viewpoints and name each visible position consistently. Left-to-right numbers are the shortest option when the layouts support them. If the two stations are arranged differently, use unambiguous position words instead and confirm what each label means.
Also agree on one meaning for the red-light signal, such as ready for the next call. That convention is a coordination method, not a hidden universal code. Do not change its meaning halfway through the attempt.
Relay the current sequence
- The Reader announces a single light using the agreed label.
- The Operator repeats the label without pressing anything.
- The Reader confirms or corrects the repeat.
- The Operator presses the matching light once.
- Both players pause and read the room's next visible state.
- Use the agreed red-light signal before moving to the next call.
- Repeat until the puzzle releases its recorded Purple Blob reward.
The repeat-back in step 2 is important: it catches left/right reversals before they become an incorrect input.
Confirm completion instead of guessing
Treat the Purple Blob becoming available as the completion check. A red flash or a single changed light can be an intermediate signal, so do not walk away until the reward state actually changes.
No universal light sequence, fixed light count, or reusable button code has been verified. Read the active room rather than copying an answer from a different world.
Recover from a stopped sequence
If progress stops, do not immediately restart with rapid guesses.
- Stop all inputs and say the last call that both players confirmed.
- Check that both players kept the same viewpoint and numbering direction.
- Test the intercom and the agreed red-light signal once.
- Resume from the room's current visible state if it clearly presents one.
- If the state is ambiguous, reset the attempt through the controls the room actually exposes, then rebuild the callout map before pressing again.
Different 2-, 3-, and 4+-player worlds can change puzzle complexity. The exact light count for every world size is not yet captured, so visible controls in your selected world take priority over any count implied by this guide.
