Outdoor escape game by Qula — not a physical escape room, but a self-guided puzzle route through Terneuzen. Terneuzen is known for its character as a port city with the Arsenaal. 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 Arsenaal, Schoolmuseum, Schelde Boulevard and Willem 1 Park. It's an independent treasure hunt without a guide, where the team with the most points wins.
