Outdoor escape game by Qula — not a physical escape room, but a self-guided puzzle route through Tiel. Tiel is known for its status as one of the ten oldest cities in the Netherlands. The City Trail takes players at their own pace through the city: on their smartphone they solve riddles and complete tasks that lead from location to location, passing by Sint Maartenskerk, the Flipje Museum, the Cannons of Tiel and Ambtsmantuin. It's an independent treasure hunt without a guide, with the team scoring the most points winning.
