What Yellow Tower Unlocks
Yellow Tower is the third stop on the recommended route. Clearing it opens the Tunnels — described by the community guide as the fastest movement option — plus all the main-area coloured doors. Once the tunnels are open, crossing the island between blorb hunts becomes dramatically quicker, so doing Yellow before your longest expeditions pays off. It also grants the Big Tunnel achievement.
The Five Blorb Puzzles
Yellow Tower's five blorb puzzles emphasise split viewpoint — different players see different fragments of information and must combine them. The verified shape:
- Blorb 1 — a split-info relay (you see half, your friend sees half).
- Blorb 2 — combine two viewpoints into one placement.
- Blorb 3 — a tunnel-adjacent navigation puzzle.
- Blorb 4 — a longer combined challenge.
- Blorb 5 — gates the tunnel entrance.
Co-Op Mechanic: Split & Viewpoint
Yellow Tower is where Big Walk leans on different players seeing different things. The fix is to externalise the info — sketch it, describe positions out loud, or use the map. Groups that hoard what they see stall here; groups that share fly through.
Difficulty & Time
Yellow Tower is medium difficulty and the most travel-rewarding. Budget roughly 30–50 minutes for the five blorbs — but the tunnels you earn save you hours across the rest of the game.
Co-Op Tips
- Once the tunnels open, use them to chain the train, cable car and shortcuts — they link the whole movement network.
- Assign a navigator who watches the map while others solve, so you don't backtrack.
- The coloured doors Yellow unlocks also open optional shortcuts worth grabbing early.
What Comes After Yellow
