Outdoor escape game by Qula — not a physical escape room, but a self-guided puzzle route through Vlissingen. Vlissingen is known for its tough maritime atmosphere and boulevard. The City Trail takes players at their own pace through the city: on the smartphone they solve riddles and complete assignments that lead from one location to the next, passing De Uncle Beach, Museum shop Mercuur, Sint Jacobskerk, Arsenaal and Rondeel, among others. It's an independent search without a guide, where the team with the most points wins.
