The blue signals near the Green Tower in Big Walk are a counting challenge dressed up as a set of stoplight-shaped monitors on poles. Each screen flashes pictures of faces in quick succession, and the whole thing hinges on your group adding up every face correctly. It looks chaotic at first, but the rule behind it is simple once your team spreads out.
Quick answer: Press the red button on the green slope, position teammates so every monitor is visible, count the total number of faces shown across all screens, then enter that number into the counter and press the verify button beside the black screen. A correct count releases the gourd for the Green Tower.
Where to find the blue signals near the Green Tower
The puzzle sits south of the Green Tower, inside a green structure that looks a bit like a set of monkey bars. You will usually run into it either on the way up to the tower or while coming back down, and it is close to the broken-down train line, so it is hard to miss.
If you are standing at the top of the Green Tower, look out over the landscape below to spot the signals before you descend. Marking the spot from that vantage point makes it far easier to walk straight to it instead of wandering the slope.
How the puzzle works
The monitors face in different directions, so no single player can watch all of them at once. Each screen shows faces one after another, and the number of faces is random every time. Your only job is to add up the total count of faces across every screen and feed that number into the counter at the main station.
Because the screens point away from each other, this is a coordination problem more than a memory test. Spread your group out and assign coverage before anything starts flashing.
Solving the blue monitors puzzle
How to know it worked
After you input the count and press the verify button, wait for the station to check it. A correct total completes the puzzle and releases the gourd, which is one of the collectibles you need for the Green Tower key. If the count is wrong, the two most likely reasons are a miscount on a screen someone struggled to see clearly, or two players counting the same ribbon and inflating the total. Re-run the puzzle, tighten up who watches which colored ribbon, and confirm nobody’s monitor overlaps before you enter the number again.
With the gourd released, this becomes one of the five collectibles feeding into the Green Tower rooftop panels, so bank it and move on to the region’s remaining puzzles.
