Full description

Experience a self-guided tour game in the heart of Cologne and get to know the city in an interactive way. Solve the puzzles and riddles of the casket using the notes of Laurenz Cronenberg, who was the master-builder of the dome of Cologne Cathedral.

Help Dr. Elisabeth Immergrün open the mysterious box found in a small cavity at the back of an altar. Use the medieval map of Cologne to unravel the mystery of how to open this precious artifact.

Start your journey to unlocking the mysterious casket in the old city. Walk through the hustle and bustle of the city's alleys and see the churches and relics from Roman and medieval times.

The search for the code for the lock of the casket takes you straight through medieval Cologne, the heart of the old town, and into a world of architects, master builders, and the Cologne way of life. On your way, you will pass many traditional breweries where you can stop for a Kölsch.
