Big Walk Five-Minute Room Puzzle
The literal answer to the Blue Tower countdown room—there is no hidden switch.

Table of contents
The coastal countdown room is intentionally literal: bring the required group inside, start every active control, let the doors lock, and wait for the full five-minute display to reach zero. There is no hidden switch to hunt. The label used here is descriptive.
Quick solution
- Find the red coastal building at approximately 3590, 2020.
- Bring every player required by the selected world inside.
- Put one player on each active control and hold them until the timer starts.
- Remain in the room after the doors lock.
- Wait for the five-minute countdown to reach zero.
- Collect the released control-panel piece.
Identify the countdown building
Descend from Blue Tower through the trees toward the beach. The red house has a large black timer display visible near its entrance, making it distinct from the nearby symbol and obstacle-course buildings.

Start every active control
The 2-, 3-, and 4+-player worlds can expose different active inputs. Walk the room before starting, assign one player to every lit control, and press or hold them together until the doors close and the display begins counting down.
Do not use a memorized player count as the authority; use the active controls shown in the current session.
Wait inside the locked room
Once the timer begins, the puzzle action is simply staying inside. The furniture and corners do not hide another step. Use the wait to regroup, check communication, or decide which Blue Tower challenge comes next.

Confirm completion
The reward unlocks when the timer reaches zero. Wait for the doors and reward state to change before leaving.
Recover when the timer does not run
| What you see | What to do |
|---|---|
| The doors stay open | Check for an unstaffed active control and restart together. |
| The display never begins counting | Make sure every required player is inside and every lit input is held. |
| A teammate left before completion | Regroup the selected-world team inside before another attempt. |
| The timer is running but the group is searching the room | Stop searching and wait for the display to reach zero. |
Continue the Blue Tower route
Take the reward to Blue Tower. The complete Trains route covers the panel, cutters, and main station. Continue to the Cooperative Obstacle Course when the group wants an active teamwork challenge.
