How it works →

"Makes me feel like I have a secret about the city."

An experience unlike any walking tour you've taken.

Step 01

Meet your historical guide.

Head to the first stop. There, you'll meet a real historical figure who shaped streets where you're standing, brought to life through rich, immersive audio drama.

Step 02

Step into their timeline.

As you reach each location, the next chapter unlocks. No modern tour guides or textbook history lessons here — only first-hand accounts from characters speaking directly from their own era.

Step 03

Unlock the streets around you.

The physical environment is your game board. Use archival photos, match real-world objects, and hunt for hidden architectural clues to progress through the narrative. If you pay close attention, you'll discover secrets hiding in plain sight.

Choose your quest.

Golden Gate Park
A Garden at the Edge of the World
A naturalist who shaped the park from the ground up

Walk through one of the most improbable parks ever built, an oasis coaxed out of barren sand dunes, ocean fog, and fierce obsession.

Your guide knew every plant by name, and he spent fifty years fighting to keep his wilderness entirely untamed. Match real-world plants to botanical illustrations and uncover the secret rivalries buried beneath the hedges. This park holds a century of hidden history, if you know where to look.

The Problem Was the Hill
The engineering miracle that conquered San Francisco

Before cable cars were an icon, they were a desperate answer to a brutal reality: horses slipping and dying on San Francisco’s rain-slicked hills. Step back to the 1870s and let a voice from the era guide you through the steep grid. Match real-world industrial relics, decode hidden cable mechanics in the modern streets, and discover the obsessive mind who risked everything to tame the slopes.

Kidnapping on the Barbary Coast
A missing boy. A lawless district. A cold case from 1879.

A 19-year-old man has been shanghaied from the San Francisco waterfront, dragged into the lawless shadows of the Barbary Coast. He's back to piece together what happened and he needs your help. Follow the trail through dimly lit saloons, interrogate witnesses, and track down the culprits before the trail goes cold.
