01 — the walk
Three beats, then the outdoors
02
Hunt
This phone asks for riddles within 8 km. You see distance, never a pin. Then you look with your eyes.

Found
Photograph it under your account. The referee is strict and sometimes says no. A real match scores both of you.
Public ground, not a meetup
Dead Drop never introduces you to the other player and never arranges a meeting. You are looking for objects, not people. Hide things only in public places you are allowed to be. Never on a private doorstep. Never anything dangerous, perishable, or that you would mind a stranger picking up and putting back.
On the hosted demo, find-photos are sent to Google AI Studio so Gemma can referee them. The riddle never includes an address, a phone number, or coordinates. Hunt uses this device's location once, shows distance only, and does not store that reading. The stash coordinates stay on the server so nearby hunters can see the riddle.
