Which Country is Richer? - World Wealth Challenge

Higher or Lower Chain features a unique chain-building mechanic where each correct guess adds a new country to your growing chain. The tension builds as your chain gets longer - one wrong guess breaks your entire streak! This creates an addictive, high-stakes learning experience that keeps you engaged.

Start with two countries to compare. Each time you guess correctly, a new country is added to your chain. Your goal is to build the longest possible chain by making consecutive correct comparisons. The longer your chain, the more impressive your achievement!

Yes! After your chain breaks, you can share a beautiful image showing all the countries in your chain, your final score, and a QR code for others to try the game. Perfect for social media sharing and challenging friends.

One wrong guess immediately ends your chain and shows your final results. You'll see your complete chain of countries, final score, and have the option to share your achievement or start a new chain.

All data comes directly from the World Bank's official database, ensuring accuracy and reliability for educational purposes. We update our data regularly to maintain current statistics across all 195+ countries.

Absolutely! Higher or Lower Chain is fully responsive and optimized for mobile devices, tablets, and desktop computers. The chain-building interface adapts seamlessly to any screen size for the best gaming experience.
