Big Walk Cooperative Obstacle Course Puzzle
A complete Blue Tower course walkthrough from the first wall to final confetti.

Table of contents
The Blue Tower obstacle course is a sequence of group gates: stack over the first wall, hold doors, lift teammates up blocks, coordinate far controls, and finish with a tomato-timer handoff. Reset the failed segment instead of restarting the whole route. The name is descriptive.
Quick solution
- Find the multicolour slope course at approximately 3700, 1950.
- Stack a teammate over the first wall and have them hold the entry door.
- Leapfrog the group up the tall blocks, then crouch under the low barrier.
- Cross the red planks and press every active far-wall control together.
- Split at the final platform: one player keeps the timer above while another reaches the holder below.
- Throw, catch, and seat the timer to open the final door and release the piece.
Find and stage at the course entrance
The course sits on the wooded slope below Blue Tower. Group up on the broad yellow entry platform before climbing; loose players arriving late can become trapped behind a held door.

Clear the wall and hold the door
Build the first player stack on flat ground. The upper player crosses the wall, finds the inside door control, and holds it until every teammate passes. Do not release the control just because the first follower is through.

Lift the group through the middle course
Use catch-and-lift handoffs on the tall block section. Crouch under the low wall, keep to the red planks, and count the active controls at the far wall before pressing. Larger selected worlds can show additional inputs.


Complete the final timer handoff
Leave the sender on the upper platform beside the tomato timer. The receiver uses the red stairs to reach the distant holder and calls ready. Send the timer only after that call; the receiver catches it and seats it immediately.


Recover the failed segment
| Failed segment | Recovery |
|---|---|
| A teammate is behind a door | Return one player to the local hold control; do not restart earlier completed obstacles. |
| The stack slips | Rebuild on the nearest flat surface and lift one teammate at a time. |
| Far controls do not register | Count the current world's active stations and press on one call. |
| The final throw misses | Return the timer to the upper start and place the receiver before trying again. |
