• Colombi Palace - Begin your adventure at Rotteckring 5 by launching the Explorial app. Enter the 6-digit game code sent via text and Viator chat, and follow the charming Bächle, the small water channels, into the historic old town. This tour is entirely self-guided—no guide, no set start time, just your group exploring the city.

The Münster serves as a central landmark: its intricate spire, often hailed as the most beautiful in Christendom, remarkably withstood the 1944 bombing. Puzzles weave through gargoyles and the bustling market sounds.

At the Neues Rathaus, trivia echoes with the carillon over Rathausplatz, where the university town’s civic pride flourishes in vibrant window boxes.

Finally, Konviktstraße enchants with its wisteria, cobblestones, and quaint craft shops, making it the most picturesque lane in the old town.

Spend approximately two hours in Germany’s sunniest city, enjoying the fresh Black Forest air. The leaderboard determines the winner, while the Bächle decide who ties the knot.
