🕵️ Bern Hide & Seek — Seeker Board

Play area: Libero zones 100 + 101. Data & timetable from transport.opendata.ch.

① Possible hiding stations

–of – still possible

Your board (clues, ruled-out stations, times) auto-saves and survives refreshes.

② Connections / travel time

Bern Bahnhof is pre-cached → instant. Other origins use the live API (rate-limited, ~1000/day).

③ Questions → eliminate areas

Each answer the hider gives carves the map into can-be / can't-be. Red = ruled out.
