Best overall: PassportQ
PassportQ is the simplest daily geography entry point: guess the mystery city from useful clues, then use distance and direction feedback to triangulate the answer.
Best map game: AirportQ
AirportQ is the strongest map-based pick because the clue is a real airport route network. The shape, range, and destination mix point to the answer.
Best trivia routine: CityQ, Chain, HigherQ
CityQ rewards category knowledge, Chain rewards speed, and HigherQ rewards city facts. Together they cover the trivia side of geography without feeling like flash cards.
Best visual puzzle: Headcount
Headcount is the visual outlier: draw one loop around a real population map and try to capture exactly the target number of people.
