JoJio is an interactive 3D geography game that challenges you to identify countries from around the world on a fully rendered, rotatable globe. Whether you are a geography student looking to improve your knowledge, a teacher searching for engaging classroom tools, or simply someone who loves trivia and exploration, JoJio provides an immersive way to learn the countries of our world.
Unlike flat map quizzes, JoJio renders a real 3D globe you can rotate, zoom, and explore. This builds spatial awareness that flat maps cannot provide.
From gentle Beginner mode with flag hints to the intense Blitz countdown, there is a challenge for every skill level. See the full mode breakdown.
One mystery country per day with distance and direction feedback. Compete with players worldwide to solve it in the fewest guesses.
Wrong guesses show an animated arc to the correct country, teaching you spatial relationships between nations with every attempt.

JoJio is built entirely with open web technologies — no plugins, no downloads, no accounts required. The game uses Three.js for real-time 3D rendering, TopoJSON for accurate world boundaries, and custom GLSL shaders for the atmospheric glow effect. Sound effects are generated procedurally with the Web Audio API, and all your data stays in your browser via localStorage.
