Global Challenge is a geography trivia game. What's the highest point in Peru? Which country has the longer coastline, Brazil or India? What countries border Azerbaijan? Global Challenge tests your knowledge of these questions and other geographical facts for over 250 countries, in 20 question categories (capitals, climate, natural resources, flags, etc.). The game features a unique weighting system that lets the game get more challenging the more you play, and that reacts to your previous results.
