Rivers have always been lifelines for human civilization. They provide water, transportation, trade routes, and often serve as natural boundaries. Many of the world’s greatest cities were founded on riverbanks — and even today, these rivers shape the identity and culture of the places they flow through. But how well do you know which rivers run through which cities? In this quiz, you'll be given the name of a city, and your challenge is to select the river that flows through it. Some city-river pairs are world-famous — think of London and the Thames, Paris and the Seine, or Cairo and the Nile. But others may not be so obvious, especially for cities where the river is less well-known internationally. Some cities even sit at the confluence of multiple rivers! Learning about these river connections helps deepen your understanding of geography and history — after all, the flow of rivers often mirrors the flow of civilization itself. Whether you’re a geography buff, a traveler, or just someone who enjoys a good quiz, this game will test your knowledge of global cities and the waterways that define them. Along the way, you’ll probably learn some surprising new facts about places around the world. Ready to follow the rivers? Let’s begin!
