City Quiz Walks turns a Stockholm walk into a quiz played on your phone. There is no guide: you follow a map, answer questions about places along the route, then see your score at the finish. The website says no download is needed; log in and start. You can go alone or with family and friends, at a time and pace you choose, or split into teams and compete.

For visitors who want English, The Old Town (English Quiz) runs through medieval Gamla Stan. It starts at the Royal Palace on Skeppsbron and finishes at the Royal Palace on Norrbro, covering about 1.5 km. The route follows winding cobbled streets and squares and asks about more than 750 years of Stockholm history. The listed duration is about 60 to 90 minutes, at your own pace.

The shop lists walks in Stockholm districts including Gamla Stan, Djurgården, Norrmalm, Södermalm and Vasastan, as well as themed quizzes about historical women and men. The historical-women route runs from Humlegården in Östermalm to Kungsträdgården in Norrmalm. It covers about 3.5 km and takes 60 to 90 minutes.
