Enjoy a unique experience in Regensburg directly with your smartphone. Let yourself be carried away into the story of astronomer Johannes Kepler, who lived in Regensburg. Our city game has been lovingly researched by us on site and has a real connection to Regensburg. While solving the puzzles of this exciting story, you will pass by Regensburg's most beautiful sights. You solve the puzzles directly with and at the sights. Work in a team (1-6 people per group) to solve the case. Are there more than 6 of you (up to a maximum of 50 people)? Then we recommend splitting up into several small groups, otherwise experience has shown that not everyone is well integrated into the game. You can also test which group is the fastest! Use our city map to puzzle your way from station to station along the story. Solve the puzzles at the most beautiful sights. Move at your own pace and take a break whenever you want.
