DIRECT ANSWER

ScreenHype's August 2026 walkthrough associates the Yellow Tower with the Yellow Tunnel, reports the tower at 3310, 1560 and the tunnel at 3500, 1620, and says five puzzle rewards release a key that is shaped through five cutters. No official page reviewed confirms those coordinates, the nearby-puzzle list, or the cutter route. Use the spoiler-light checks first and treat every precision detail on this page as that outlet's single-playthrough report.

What is confirmed

  • Official sources confirm cooperative puzzles, communication tools, and 2-player, 3-player, and 4+ world configurations; they do not name the Yellow Tower or tunnel.
  • ScreenHype publishes a dated, illustrated Yellow Tower route with six nearby puzzle candidates and a five-reward panel.
  • The exact coordinates, puzzle labels, role sequences, tunnel purpose, and key-cutter route on this page all depend on that single outlet unless stated otherwise.
  • The official FAQ tells the host to use the accessibility menu when starting a session, but it does not give a button-by-button path or explain the setting's effect on this tower.

Before the route: confirm you are at the right landmark

No-spoiler check: look for a yellow-coded tower area and a separate tunnel entrance rather than assuming every yellow object belongs to the same objective. Record your host's world choice before comparing a guide. The official FAQ confirms three configurations and says some world details change; it does not identify which Yellow Tower targets scale.

ScreenHype reports 3310, 1560 for the tower. Its tunnel route goes southeast from the tower, descends the south side of the mountain, and follows the rock face to an entrance reported at 3500, 1620. These coordinates are useful as recovery points after the in-game map is available, but they are not House House coordinates and Big Walk HQ has not repeated the walk.

Editorial preparation: regroup before starting a puzzle, decide who describes and who acts, and keep a light source available if the route runs into night. The PlayStation hands-on report observed that darkness affected exploration and that groups sometimes split briefly, while the official design makes staying in contact part of the challenge.

Keep in mind

Single-source route: if the colour, terrain, or mechanism does not match ScreenHype's description, do not force the coordinates. Verify the host configuration and game version, then identify the landmark again.

Choose five reported reward puzzles

ScreenHype documents six nearby candidates while saying the tower panel needs five rewards. That gives a group a practical choice: inspect the mechanisms and leave the least comfortable challenge for later. The article also frames these as puzzles its group completed near the tower, so this page does not call them the only valid Yellow Tower rewards.

Hint level 1: inventory the roles before touching a start control. The reported set includes collecting coloured pieces, comparing sounds, matching audio across separated rooms, mirroring stage directions, carrying symbol pieces between aerial platforms, and relaying light positions between buildings. Those descriptions come from ScreenHype's photographed route, while the broader communication patterns also fit the official design baseline.

Hint level 2: choose a communication protocol suited to the obstacle. For sound, number or name each source before the sequence begins. For mirrored directions, agree whether instructions refer to the viewer or operator. For remote lights, name walls and positions while both players can still talk. For item transport, decide who reads the target order and who moves pieces.

Progressive hints for the six documented candidates

Collection puzzle — Hint 1: search by colour and elevation, not in a single flat circle. Hint 2: the ScreenHype route says some pieces require using terrain or a tunnel approach. Full-source warning: the same article reports four types and a large collection total in its two-player run, but this site does not universalize that quantity across configurations.

Sound puzzles — Hint 1: treat the challenge as comparison and memory, not musical performance. Hint 2: assign stable names or numbers to every microphone or speaker before pressing anything. ScreenHype describes one open sound-check structure and another split-room music comparison, but exact prompts can be configuration- or attempt-dependent, so no fixed answer string is published here.

Stage-direction puzzle — Hint 1: the clue and buttons are viewed from opposite sides. Hint 2: translate the light position into the operator's perspective before signaling. ScreenHype reports a seven-position panel and recommends sending the converted position through gestures. The core useful rule is perspective reversal; this page intentionally avoids claiming that a particular light number is the current answer.

Aerial-seat puzzle — Hint 1: one side shows candidate pieces and the other shows the required order. Hint 2: use the moving chair as the information-and-object bridge. ScreenHype also describes a faster item-carrying approach, but that shortcut may depend on available storage and physics, so the supported route here remains compare, select, transport, and place.

Cliff-room puzzle — Hint 1: one building supplies light information and the facing building supplies buttons. Hint 2: use the communication point between them and describe wall plus relative position. ScreenHype reports this at 3290, 1670. The coordinate, room roles, and exact repetition count are single-source details.

Keep in mind

Third-party single-source hints, not official: all six candidate descriptions and coordinates in this section come from ScreenHype's photographed route.

Tower completion and tunnel unlock — full spoilers

Full progression spoiler: ScreenHype says five earned rewards are placed into the panel on top of the Yellow Tower. A key becomes available behind the panel. The guide then takes that key to a cutter near the tower door and follows the revealed arrows through four more cutters before using the final shape at the Yellow Tunnel lock.

This is the only directly readable walkthrough used for the exact sequence, so Big Walk HQ does not reproduce its turns, screenshots, or claims about what lies beyond the tunnel. If the first cutter or arrow is missing, confirm that all panel slots are visibly satisfied and that you picked up the released key. Those are logical checks based on the reported mechanism, not a guarantee that every current build responds identically.

ScreenHype calls the tunnel part of later progression and mentions additional discoveries beyond it. To avoid unnecessary story spoilers, this page stops at the door. Continue with your group and let the game reveal the destination rather than treating a guide's post-tunnel description as required preparation.

Keep in mind

Evidence boundary: Yellow Tower → Yellow Tunnel, the five-reward panel, and five-cutter path are all one ScreenHype account. House House's official pages reviewed for this build do not document this chain.

FAQ / VERIFIED ANSWERS

Frequently asked questions

What does the Yellow Tower unlock?

ScreenHype reports that it unlocks the Yellow Tunnel. The official FAQ and press kit reviewed for this build do not name that tower-to-tunnel relationship, so it remains an attributed single-source claim.

EvidenceHow to Unlock the Tunnels in Big WalkBig Walk Frequently Asked QuestionsBig Walk Press Kit

Where is the Yellow Tower?

ScreenHype reports 3310, 1560. Treat that as the guide author's observed coordinate, not an official marker, and use visible yellow structures and terrain to confirm the location.

EvidenceHow to Unlock the Tunnels in Big Walk

Do I have to solve all six nearby puzzles?

The ScreenHype route documents six candidates but describes a five-reward panel. That supports choosing five from its nearby set; it does not prove every reward is interchangeable in every world configuration.

Are the Yellow Tower solutions the same for every group size?

Do not assume so. House House confirms that some things change between the 2-player, 3-player, and 4+ worlds, while the exact steps here come from one outlet's playthrough.

Can we skip a Yellow Tower challenge?

The official FAQ says the host enables challenge skipping from the accessibility menu when starting a session. It does not provide a button-by-button walkthrough or explain exactly how that option affects this tower.
