Big Walk Guide

Map and coordinates

16 verified coordinate points, ordered by progression. This page answers three things: how a coordinate is read, which puzzle each coordinate belongs to, and how far the target is from where you are standing right now.

Learn to read a coordinate first

Coordinates in the game are four-digit numbers, formatted like 4166, 1899 or 3930, 1900. You read them like this: the first two digits number the vertical grid line, and the last two subdivide within that cell. So 4166 means vertical line 41, 1899 means horizontal line 18, and the intersection is your target cell.

Schematic: how to read a coordinate. 4166 means vertical line 41, 1899 means horizontal line 18, and their intersection is the target cell.

Prerequisite: until you have the folding map from the red tower, these numbers are gibberish to you. This is the single biggest reason coordinate puzzles trap people - not that you cannot read them, but that you have no tool that makes them readable yet.

Coordinate finder

Type in the two numbers on your screen and we tell you which verified location you are closest to, by how much, and which guide to open. This one tool is the reason this site exists - every piece of data it needs (13 cross-checked coordinate points) is already here, whereas elsewhere you get either a static image or a long table.

Any format works: 4166, 1899 and 4166 1899 both parse.

  • Red tower
  • Green tower

The chart only shows the 13 locations whose coordinates could be cross-checked. The yellow, blue and black tower areas have no reliable sources, so they are not plotted - that is not a missing drawing.

Coordinate quick reference

16 points

Coordinates marked community field report come from a single guide source and may shift between game versions - once you arrive, trust the landmark description.

Note that the yellow, blue and black tower areas have no coordinate points listed here. That is not an omission - those regions currently have no sources that corroborate each other, so we do not publish numbers. Following a landmark description on the tower page beats following a figure that might send you somewhere wrong.
