A mad criminal is threatening Aarau. He has hidden CO₂ capsules in ventilation systems that will open in 2:30 hours if you can't crack the secret code by then.
Start the timer, solve puzzles at different locations with team play, and chat with the mad criminal. Work together as a team and solve each puzzle collectively.
Discover alleyways with colourful gables in the historic Old Town and other spots in Aarau. These include, for example, the Haldentor, the Casino Park, the Schlossmühle, or the Aare. Along the way, you will also learn interesting background information about lung health.
You can visit the puzzle locations in any order. Decide together on the quickest route and the best strategy. The total distance is about 4 to 5 km. At the end, assemble the collected puzzle pieces and find the solution.
These tickets can't be rescheduled or cancelled.
