Simple choice, real facts
Every round asks for one comparison, but the underlying facts are real city data. That keeps the game fast while still teaching useful geography.
Multiple comparison modes
Population tests city scale, elevation tests terrain, age tests urban history, equator distance tests latitude, and weather tests daily climate intuition.
Streak pressure
One wrong answer ends the run, so easy-looking comparisons still carry tension once the streak is high.
Best warmup game
HigherQ works well before slower puzzles because it builds anchor facts for cities you will see again in PassportQ, CityQ, and Geo Blackjack.
