How to play the game.
Each round, you’ll see two cities. Your job is simple: tap the city that’s farther north.
“Farther north” means the higher latitude.
After you pick, you’ll get a crisp breakdown showing both latitudes, the latitude gap, the distance between the cities, and the points you earned.
Game modes:
Endless: keep the streak alive as long as you can. One wrong pick ends the run.
Daily: one curated set of 10 rounds per day. You get one guess per round, and your final score is your total across all 10.
Prefer keyboard? Use Left/Right arrows or A/D to choose.
Nerd notes: Difficulty comes from the latitude gap (closer = harder = higher base points). A distance multiplier then nudges points up for far-apart cities.
The formula is base(tier) × (1 + 0.5 × clamp(distanceKm/8000)).
Data: a curated list of major cities, pulled from the dataset’s top entries by population.
