About the game
Every day, thousands of people cross the Charles Bridge. Most see Prague Castle, the Vltava River, and a row of statues. But very few know where to truly look.
Hidden in the stones, inscriptions, and statues of the bridge are traces of its more than six-hundred-year-old story. Who really built it? What does the mysterious sequence 1–3–5–7–9–7–5–3–1 mean? And why do tourists still touch certain spots for good luck?
During the game, you'll use your mobile phone to search for hidden details, crack ciphers, work with real inscriptions, and solve puzzles right on the bridge. You'll encounter Charles IV, Peter Parler, Wenceslaus IV, and John of Nepomuk.
No app, no tour guide with an umbrella. Just you, your phone, and the Charles Bridge as one giant cipher.
