Snabba Cash is a self-guided city-walking game in Stockholm. It uses the StoryTourist app to bring Jens Lapidus’s bestselling thriller to central Stockholm, where visitors follow the plot on location. The game combines a mobile game with a GPS-guided walk and an action audio production. Players follow Jorge, JW and Mrado through a showdown in the city’s underworld. Visit Stockholm says the activity gives residents and visitors a way to explore Östermalm as it was in the early 2000s. Charge your phone and bring headphones, the city’s listing advises. The activity brings together walking, app-based play and audio as the characters and plot lead the experience through Stockholm. The listing gives no price, opening hours or estimate of how long a visit takes. It describes the walk as self-guided and GPS-guided.
