This one is about positioning, not memory. The more players you have, the easier it gets - a full team puts one person on every screen.
Before you start
- 2 players or more (more people is genuinely simpler)
Step-by-step 5 steps
- 1
Do not walk in yet, look at the structure
Go to the green jungle-gym structure beside the broken train and work out how many screens there are and which way each one faces.

Press the entrance switch
Hit the switch at the entrance and the screens start showing content.
Faster: Take your positions first, then press the switch. If you press it and only then look for a spot, you will miss screens.

Each player counts only the faces in front of them
Spread out until every screen has at least one viewer. Each person counts only the faces they can see and reports their own local number. Every screen gets exactly one counter - if two players' views overlap the same screen, its faces get counted twice.
Schematic: correct positions for the face-counting puzzle, drawn with three screens as an example. Every screen needs a watcher, each counts only what they see, then add them up. Count the screens on your own structure first - the number in the drawing is not a fixed layout. - 4
Add them up into one total
Sum everyone's number into a single total. The faces are generated randomly on every attempt, so a wrong entry kills the old numbers and the whole team recounts from scratch before re-entering.

Enter it on the blue panel
Punch the total into the blue panel device. If it is right, the collectable unlocks.
Where it goes wrong
These are the places players actually get stuck most often. Working through them in order usually finds the cause.

After finishing: 1 green tower part.
Where this solution came from
allthings.how, games.gg and bigwalk.tips agree: press the entrance switch, spread out to cover every screen, total the count and enter it on the blue panel. bigwalk.tips adds the two failure modes - an uncovered screen, and a face counted twice.
Puzzles in this game are not assigned in a fixed order: each tower needs a set number of gourds and has more challenges around it than that, so you choose which ones to clear, in any order. That is why two guides list different puzzle line-ups for the same tower — neither is wrong. Unless a coordinate is credited to a named source it is a community measurement, and later versions can shift it; once you are in the area, trust the landmark over the number.
