Outdoor escape game by Qula — not a physical escape room, but a self-guided puzzle route through Amsterdam. There are 2 different routes in Amsterdam. Amsterdam is known for its canal ring, the Royal Palace and Dam Square. The City Trail takes players at their own pace through the city: on their smartphone they solve riddles and complete tasks that lead from place to place, including the area around Oude Kerk, Dam Square, Anne Frank House and the canals. It's an independent treasure hunt without a guide, where the team with the most points wins.
