What this page is for

This is the Green Tower Head Count puzzle: a teamwork challenge built around shared observation and a changing number. It is not a keypad that expects 4166 or 1899.

The coordinate labels are included because players may arrive here after seeing 4166, 1899 in a community note. Other public guidance places the matching arena closer to 4100, 1880, so use the visual landmarks below to confirm that you are in the right place.

Recognize the right puzzle

Look for a green arena near the Green Tower with:

  • blue lamps arranged around the space;
  • white globes where the silhouettes appear;
  • a raised control that starts the sequence; and
  • a blue counter for the final total.

If the scene does not match, do not force the coordinate label. Big Walk’s landmarks and routes are more useful than a copied number.

Make it a group task

The puzzle becomes much easier when every player owns a small viewing zone. Before anyone touches the start control, agree on the first and last lamp in each zone and give each zone a simple name, such as “left stripe” or “upper pair.”

Once the sequence begins, each player counts only the dark head silhouettes in their own globes. Keep the subtotals separate until the animation finishes. One player can then repeat the totals back and enter the sum on the blue counter.

This is the same communication pattern that appears across Big Walk: split the information, keep the signal clear, then recombine the pieces at the end.

Why another group’s number may fail

  • Two players counted the same lamp.
  • One globe was outside everyone’s viewing zone.
  • The activating player missed the first silhouettes while moving back.
  • Someone counted lamps instead of the heads inside them.
  • A previous walkthrough’s example total was copied even though the current sequence differs.

If the counter rejects the total, reset the viewing zones before changing the arithmetic. The method is stable; the number is the part that belongs to your current attempt.

Coordinate note

The precise 4166, 1899 alias has not been independently matched in-game by this site. Keep the older URL as a useful search entry, but use the Green Tower, green arena, blue lamps, and white globes as the real identification check.
