Free Geography Games

Physical and human geography, including the parts that are reasoning rather than recall. Biome Builder makes you deduce a region's biome from latitude, altitude and rainfall instead of remembering it. Drift Apart has you rotating continents back into place on a blank globe. Border Hop gives you a start and a destination and asks you to cross from country to bordering country in as few steps as possible, which turns a map into a graph. Flags, capitals, time zones, coordinates, population and trade are all covered too.
