Knowing a country's continent is the entry level. Knowing which part of that continent it sits in is what turns a 250-point round into a 650-point one. Regions are the missing layer in most people's mental map — this is that layer, organised.
CityDrop's location settings let you play the world, a single continent — Africa, Asia, Europe, North America, South America or Oceania — or a single country from the playable list. That mirrors how the map is actually organised, and it is a good sign of the level you should be thinking at: continent first, then sub-region, then country.
A few countries straddle the line. Russia spans Europe and Asia, Turkey and Georgia sit on both sides of the Bosphorus and Caucasus, Kazakhstan and Azerbaijan reach into Europe, and Egypt's Sinai is conventionally Asian. The Ural Mountains, the Caucasus and the Bosphorus are the usual dividing lines.
The quickest way to make regions stick is to attach one or two cities to each. If you can picture Nairobi, Lagos, Cairo, Jakarta, Bogotá and Helsinki on the map, you can orient yourself almost anywhere nearby.
Next step: once the regions feel familiar, learn which countries sit beside which in borders and neighbours.
