Today's weather, not a trivia table
Most temperature quizzes test climate averages, which reduces the game to memorized normals. HigherQ compares today's high temperatures from live data, so the puzzle is part geography, part meteorology: latitude and elevation set the baseline, but season, hemisphere, and this week's weather decide the round. A desert city on a cool snap can lose to a humid coast, and a famous cold city can win a summer matchup you would never expect.
The streak is the score
The format is endless higher-or-lower: call each comparison correctly and the streak grows, miss once and the run ends. Early rounds feel easy, but the game gets sharp when two cities sit within a couple of degrees of each other and you are twenty deep into a streak you do not want to lose.
What the game quietly teaches
A few dozen rounds build real instincts: hemispheres flip seasons, elevation cools cities that look tropical on a map, coastal water moderates extremes, and continental interiors swing hard. Those are exactly the instincts PassportQ rewards, since today's high temperature at the mystery city is its opening clue — the temperature mode doubles as training for it.
Four other modes when you want variety
Temperature is one of five HigherQ modes. The others compare cities by population, elevation, age, and distance from the equator, so the same higher-or-lower streak format can drill whichever city facts you are weakest on.
