In the shadowed courts of King's College, Cambridge, where Alan Turing honed his genius in the 1930s, a final Enigma code lurks unsolved
King's College — Turing's Enigma Code
You are Christopher Strachey, computer scientist and friend of Alan Turing, in Cambridge, 1954.
Your mission is to retrace the final months of the British genius.
Walk in Alan Turing's footsteps through Cambridge, from King's College to the laboratories where modern computing was born.
A game, a guided tour and a heritage guide — all in one
You're not just buying an escape game. You're carrying a living guide — historical anecdotes, forgotten legends, key monuments, hidden architecture — unfolding as you go.
At each stop, places ordinary guides miss — secret façades, sculpted crests, alleys steeped in history.
Every riddle is rooted in a real historical fact or local legend. You leave with dozens of stories to tell.
Learn to read buildings — flamboyant Gothic, Baroque, Art Deco — like a real art historian, while having fun.
Walk through the city like a novel's character — every alley becomes a stage, every square a theatre.
A voice walks with you at every step, tells the story of each place, reads clues, adds a cinematic feel.
Keep access to the guide & game for 1 year. Come back any time, share it with friends.

The story that haunts this land
Cambridge welcomes Alan Mathison Turing in October 1931, when the 19-year-old mathematician enters King's College to study mathematics. King's College Chapel, built between 1446 and 1515 under Henry VI, becomes the daily setting for his meditations — this 88-meter cathedral, one of Europe's largest university chapels, where Turing attends religious services during his formative years. In January 2024, Antony Gormley's commemorative sculpture (steel, 12 feet high) was unveiled in the adjacent gardens, permanently marking the genius's imprint on Cambridge.
Gibbs Building, constructed between 1724 and 1732 by James Gibbs, houses Turing during his Fellowship at King's College from 1935. This exemplary Georgian architecture, located between Gibbs Building and Webb's Court, becomes the secret laboratory where his revolutionary theories on calculating machines are born. It's exactly at this location that Turing's sculpture was erected in 2024, immortalizing the place where the mathematician conceived the theoretical foundations of the modern computer, well before the first prototypes came to life.
Mathematical Bridge, wooden bridge built in 1749 by William Etheridge according to pure mathematical principles — without nails or screws — becomes Turing's daily passage between King's College and his academic workplaces. This structure of perfect geometry, restored in 1866 then 1999, symbolizes the Turingian obsession with mathematics applied to architecture. Each crossing of this 1749 bridge nourishes his reflection on logical machines, prefiguring his work on computability that would revolutionize global computing.
Senate House, James Gibbs's neoclassical building (1722-1730) standing 65 feet high, in Ketton stone, hosts the university ceremonies where Turing defends his thesis and receives his academic distinctions. This central administrative building of Cambridge becomes the official witness to the mathematician's journey, from his early student years to his recognition as Fellow. The Computer Laboratory founded in 1937 on Corn Exchange Street, directly inspired by Turing's theoretical work on ACE and Pilot ACE machines, materializes the genius's legacy in Cambridge's modern architecture.
Your Cambridge journey reveals how a 19-year-old student transformed a medieval university town into the cradle of global computing. From King's College Chapel to the Old Schools (1350-1754) where Turing took his mathematics courses, every stone keeps the memory of the Enigma codebreaker who changed the course of World War II at Bletchley Park. In 135 minutes of walking, you've followed the traces of the mathematician who invented theoretical artificial intelligence, 20 years before the first computers confirmed his genius intuitions.
The Route
8 stages through the city
The gameplay: AR, camera, hidden clues
At each stop, open your phone camera: an augmented reality character appears on the façade and speaks your language. Hunt the clue — it materializes as golden letters on the real wall or floats in front of you. When you find it, the phone vibrates, an AR chest opens and reveals your answer fragment. 8 stops, 8 clues to find with the camera, 1 final code.
The stops on your route are a surprise. You'll discover them one by one, guided by your phone, starting from the meeting point.

Frequently asked questions
Q01Do I need to download an app?
No, never. You get a link, you click, it plays in your browser. That's the point of a PWA: same as an app, without the hassle.
Q02Does it work offline?
GPS yes (handled by your phone). Maps yes (tiles cached). AI and hints need an intermittent 4G connection.

1 h 30 to 2 h 30 depending on your pace. The timer runs but only for the leaderboard — you play at your own tempo.
Q04What happens if I'm stuck?
You get 3 levels of hints per puzzle (increasing penalty). If truly stuck, you can skip the step (45-min penalty but you keep going).
Q05What's the age range?
From 12 without an adult, from 6 with an adult reading puzzles. Works for families, couples, friend groups, companies.
Q06What if my city isn't in the catalogue?
Pre-register or contact us — we'll email you as soon as your city is live.
Q07What is augmented reality exactly?
