City quests
A treasure hunt of riddles on foot. Walk, solve, discover — alone or against your friends.
How a quest works
Each riddle points at a real place. Walk there, and the question unlocks: something you can only answer by looking around you. No cheating from the sofa.
No city quests in Arnhem yet. These are the nearest — Amsterdam.
