Outdoor escape game by Qula — not a physical escape room, but a self-guided puzzle route through Zwolle. There are 2 different routes in Zwolle. Zwolle is known for its character as a historic and simultaneously hip cultural hotspot. The City Trail takes players at their own pace through the city: on the smartphone they solve riddles and complete tasks that lead from place to place, including De Wijndragerstoren, the Peperbus, the Zwolse Balletjeshuis and the Herman Brood museum. It is an independent treasure hunt without a guide, with the team earning the most points winning.
