Capitalibrate

Capitalibrate is a daily geography challenge where you're given two world capitals and must set the starting compass bearing and estimate the distance along the shortest globe route between them.

Each round gives you a departure capital and a destination capital. Your job is twofold: first, choose the direction you'd begin traveling (in degrees from north) along the great circle route. Then estimate how many miles separate the two cities.

• You get 5 rounds per daily puzzle.
• For each round, set the starting bearing using a compass dial (0 to 360 degrees).
• Then estimate the distance in miles or kilometers.
• Scoring rewards accuracy on both bearing and distance.
• A new set of capital pairs drops every day.

Why we like it:

• ✅Sharpens your mental map of the globe in ways flat maps never do.
• ✅Great circle routes can surprise you, especially near the poles.
• ✅Quick enough to play in under five minutes but tricky enough to keep you humble.

Hint: Remember that the shortest path between two points on a sphere is rarely a straight line on a mental map. East to west routes at high latitudes often curve far north or south of where you'd expect.
