Outdoor escape game by Qula โ not a physical escape room, but a self-guided puzzle trail through Den Haag. In Den Haag there are 2 different routes. Den Haag is known for its role as a capital city where culture and politics come together. The City Trail takes players at their own pace through the city: on their smartphone they solve riddles and tasks that lead from place to place, exploring the Binnenhof, the Lange Poten, Plein and the Passage among others. It's an independent treasure hunt without a guide, where the team with the most points wins.
