Hidden City

Hidden City provides real-world adventure games in London, where participants solve clues sent to their phones to uncover secret locations and complete challenges. These treasure hunt-style experiences are themed and offer a competitive element with a leaderboard and prizes for successful teams.

Hidden City offers real-world adventure games that are guided by a phone, similar to the concept of Wonderwise. Users select from themed story-led adventures (e.g., James Bond, Moriarty's Game), which aligns with 'themed-campaign-selection'. The games involve solving clues and completing challenges at secret locations across the city, directly matching 'location-based-quests'. Furthermore, Hidden City explicitly mentions a 'Leaderboard' and offers prizes for successful teams, which corresponds to 'leaderboard-rewards-system'. While it doesn't explicitly mention an interactive map navigation, the core gamified, location-based adventure experience with themed campaigns and rewards is strongly present.
