The same photo-then-feedback loop
WhereTaken's loop is look, guess, learn the distance, guess again. PassportQ keeps every beat: the mystery city opens with visual and landscape clues, and each wrong answer returns how far off you were and which direction to move. The arrows turn a blind first guess into a converging search — the core satisfaction WhereTaken players are there for.
Clues a photo can't give you
Photos reward having been somewhere; data rewards understanding it. PassportQ layers temperature, population, elevation, and local time on top of the visuals, so a city you've never seen can still be deduced — 30°C in January with a UTC+7 clock eliminates most of the planet before you've placed a single landmark.
Five thousand cities deep
Photo games live and die by their location pool. The city pool here spans 5,000+ places worldwide and rotates daily with no repeats inside a month, so the long tail stays genuinely unfamiliar — you will get days where the answer teaches you a city you've never heard of, which is rather the point.
