Yuyuan Road Chapter

One challenge letter turns a quiet Shanghai street into a game board. Read the buildings, signs, shadows, and stories to follow the secret JARGO left behind.

Open the challenge ON FOOT · 2–3 HOURS · 1–4 PLAYERS

CASE 01

A LETTER FROM JARGO

A challenge has arrived on Yuyuan Road.

Break the seal and you will not find an address. Instead, JARGO gives you a way to read the street: an old residence, lettering above a shop, the shape of a window, a detail that feels slightly out of place.

SETTING
Yuyuan Road, Shanghai
FORMAT
Self-guided paper mystery

Curious minds welcome

CASE 03

HIDING IN PLAIN SIGHT

Yuyuan Road is not the backdrop. It is the witness.

The answers are not hidden on a screen. They live in old gates, house numbers, decorated windows, shopfront words, and shadows on the pavement. Each real detail leads to the next chapter.

01Compare shapes
02Read local memory
03Connect what feels unusual

CASE 04

THE SMALL ODDITY

One card can make a familiar building look completely different.

Hold a clue against the scene in front of you and an overlooked outline begins to appear. Do not rush the answer. Stop, change your angle, and look again.

The order of the papers, the moment each seal is opened, and the feel of the booklet are designed around the rhythm of discovery. This is a journey you advance with your hands.
