Big Walk Hand Signals: Communicating Without Radios

Updated 2026-09-03 · Steam Big Walk

Big Walk hand signals are not a menu of built-in emotes. The game gives you arms you can point, wave and flail with, listed on the Steam store page under a feature called Arms and described as a way to get a message across when talking is off the table. Everything beyond that is a code your group invents: a few agreed poses and counts that mean something specific to you. Players who have finished the challenge puzzles say a pre-arranged gesture system is the most reusable trick in the game, because one code works on puzzle after puzzle.

Why signals matter: voice does not travel

Big Walk runs on proximity voice chat. The store page describes voices fading with distance, echoing along corridors, muffling through walls and crackling over walkie-talkies. That is deliberate. When House House patched voice volume in 1.4.8 (7 August 2026), they raised quiet microphones toward the intended level but said the distance at which voices drop away was left alone, calling that falloff a specific and important part of how the game plays. The fix made friends louder up close and at middling range, not audible from the next ridge over.

That leaves a real gap. You split up, someone climbs a tower, and the only channel left is line of sight. Fandom's overview makes the same point: the island is large and voice range is short, so getting separated is normal and groups fall back on other signals to regroup.

What your arms can do

Action	How it works	Where it is documented
Point (left hand)	Bound to the left mouse button by default on PC	Mod README describing the game's pointing state
Point (right hand)	Bound to the right mouse button; both hands at once is allowed	Same README
Wave and free-form gesturing	Listed on the store page as a way to communicate when you cannot talk	Official Steam store description
Throwing and arm movement basics	Taught by posters in the Tutorial Zone	Fandom Tutorial Zone page

Two independent hands is the important part: a signal can carry a value, not just a direction. Which hand, how high, how many times. That is the basis of every code below, and the Tutorial Zone is where the game teaches those arm basics, so send a brand new player back there before the drawbridge.

The community signal chart

One Steam guide, Hand Signals for Long Range Communication With No Radios, publishes a letter-by-letter chart for spelling words across a distance. The author's only written instruction is that letters are arranged by how common they are, so when decoding you read from the top down and stop at the first match. The chart is an image rather than text, so this wiki does not reproduce it; read the letter assignments from the guide directly.

Two caveats. It is one player's invention, not an official system, so nobody in a public lobby will know it, and spelling more than a word or two at telescope range is slow. Most groups take it as inspiration and build something shorter.

Building a code that actually works

The most detailed player account comes from the author of the 100% achievement guide and its companion guide to the seven purple challenge puzzles. Their advice, presented as what worked for their duo rather than as a rule, is to attach gestures to labels rather than meanings: number the things on screen, then signal the number. Here is how they describe the nine-speaker challenge, where talking is not allowed. Player-tested, not official:

Situation	Code they used	What it communicates
Nine sound pads laid out four, four and one	Left arm raised N times, right arm raised N times, both arms for the odd one out	Which pad in which row
Nine symbols, same room split	The same pre-agreed gesture set, reused	Which symbol to press
Light-hunting challenge, one player has only a red lamp button	One flash yes, two flashes no	Answers to spoken yes or no questions
Anything has gone wrong	A rapid burst of flashes	Stop, reset, start the question over

Three principles fall out of that, and they generalise beyond the challenge area:

Agree the code before you split. Players report the same gesture vocabulary carried across many different puzzle types without being reinvented, which only works if it is settled in advance.
Encode positions, not concepts. Left, right, both, and a count is a tiny alphabet that covers a surprising number of grids. Trying to mime "the flower one" ends badly.
Reserve an error signal. A burst meaning "ignore everything, restart" beats any extra letter, because a silent puzzle with no undo is where groups lose runs.

The 36-drawings challenge is the counter-example: it allows talking, and the same guide's advice there is to interrogate details out loud. Signals are for when speech is blocked, not a substitute for it. More on those rooms is on puzzles.

When to use a tool instead

Signals are free, but the island is full of communication items that beat them at range. Item behaviour below is from the community Fandom item pages.

Item	What it does	Where it is found
Walkie-talkie	Voice across long distance; holding transmit blocks incoming audio, like the real thing	Paired holders around the island, per a player-made locations guide
Megaphone	Pushes your voice well past default proximity range	Three yellow stepped pedestals; patch 1.5.1 (28 August 2026) increased the voice-amplifying item's reach
Flare gun	Fires a flare upward to show where you are, and doubles as a light	Starting Area and elsewhere
Laser pointer	A red beam for indicating a distant object, or aimed skyward so people can find you	Tower tops and the Map Room
Whiteboard	Type a message for others to read	Outside the Map Room, plus one behind the GPS
Cowbell	Rings as an attention-getter	Tutorial section
Binoculars	Not a signal, but what lets you read someone else's from a ridge away	Tower tops

A pairing players recommend for vertical splits: one person up a tower with binoculars, one on the ground with a laser pointer or big arm signals. Spot lists live on megaphone locations and radio locations, and every item is catalogued on items. The handheld radio is a music receiver for unlocked channels, not a comms device, despite the name.

Silent-by-design puzzles

Some rooms remove speech on purpose, which is where a rehearsed code stops being a novelty. Fandom documents a soundproof puzzle in which one shape lights up inside a sealed room and whoever is inside must get the matching button across without speaking, over several rounds. A separate symbol-peg puzzle seals one player in with an arrangement they have to relay outside, and leaving early resets everything.

Both are the shape the numbering trick is built for. Decide your labels while you are still standing together, then close the door. New groups should start with guide; the voice-settings side is on multiplayer.

Sources and last check

Checked 3 September 2026. The letter chart's existence and reading order come from the Steam guide Hand Signals for Long Range Communication With No Radios; its chart is an image and is not reproduced here. The numbered-gesture codes, the one-flash-yes and two-flashes-no convention and the reset burst are player-tested methods from the author of the purple challenge puzzles guide and the Big Walk 100% Achievement Guide, not official mechanics. Arm and gesture features and the proximity voice description come from the official Steam store page. The falloff distance being intentionally unchanged is from House House's 1.4.8 announcement of 7 August 2026; the voice-amplifying item's increased range is from the 1.5.1 notes of 28 August 2026. Item behaviour, the Tutorial Zone posters and both silent puzzles are from player-written Fandom pages, and walkie-talkie and megaphone placements are player-reported from Steam location guides. Which mouse button drives each hand comes from a Thunderstore mod README reading the game's pointing state, not official documentation, and is not confirmed for controller or console players.
