Everything you need to know about JoJio, the interactive 3D geography game.
JoJio is a free interactive 3D geography game where you guess countries on a rotating globe. Built with Three.js, the game renders a fully interactive globe with country borders, a dynamic Fresnel shader for atmospheric effects, and multiple game modes designed to test and improve your knowledge of world geography.
The game is designed for geography enthusiasts of all ages, from beginners learning their first countries to experts who can identify every nation on Earth by shape alone. No account or personal information is required to play.
Yes, JoJio is completely free to play. There are no premium features, no subscriptions, and no paywalls. The game is supported through advertisements. You can play unlimited games across all modes without spending anything.
JoJio includes approximately 180+ countries across all inhabited continents. Each country is categorized by difficulty level:
Easy (Difficulty 1): Well-known countries like the United States, China, Brazil, Japan, Australia, and major European nations. These are great for beginners.
Medium (Difficulty 2): Less obvious countries like Uruguay, Cambodia, Senegal, Myanmar, and Iceland. These require more geographic knowledge.
Hard (Difficulty 3): Small or obscure countries like Liechtenstein, Comoros, Nauru, Tuvalu, and Djibouti. These are for geography experts.
Not every tiny territory is included, but all internationally recognized sovereign nations are represented.
JoJio features 8 distinct game modes, each offering a different challenge:
Beginner: 40 rounds starting with easy countries and progressing to harder ones. You see each country's flag as a hint. Neighboring countries pulse on the globe when you use hints.
Normal: 80 rounds covering all difficulty levels. Flags are not shown, but continent and neighbor hints are available.
Hard: All countries in random order with no hints. For geography experts who want the ultimate challenge.
Flag Quiz: 30 rounds where you identify countries solely by their flags. A great way to learn world flags.
Sprint: A 60-second speed round. Answer as many countries as you can before time runs out.
Marathon: Keep going until you lose all 3 lives. One wrong answer costs one life.
Blitz: A 15-second countdown timer. Answer correctly to add time, answer wrong and lose 5 seconds. How long can you survive?
Daily Challenge: One mystery country per day, unlimited guesses. Get distance and direction feedback to narrow it down. Same country for all players worldwide.
The Daily Challenge picks one random country each day using a date-based hash, so it's the same for all players worldwide. You don't see the country name upfront — you type guesses and receive feedback:
Distance feedback: How far your guess is from the target in kilometers.
Compass direction: Which cardinal direction (N, NE, E, SE, S, SW, W, NW) the target lies from your guess.
Color-coded markers: Each wrong guess places a marker on the globe. Colors shift from red (far) to yellow to green (close) based on distance.
You have up to 10 guesses to solve it. Once you solve it or use all 10 guesses, you must wait until tomorrow. Your result is saved locally so you can't replay the same day's challenge.
Scoring varies by game mode, but the standard system works as follows:
Base points: 10 points per correct answer.
Speed bonus: +5 for answering within 3 seconds, +3 within 5 seconds, +1 within 10 seconds.
Streak bonus: When your streak reaches 3 or higher, you earn +2 per streak level (so a 5-streak gives +10 bonus).
Hint penalty: Each hint used costs -2 points (minimum score per correct answer is 1).
In Blitz mode, correct answers add time to the clock instead of points, and your score equals the total number of correct answers. In Sprint mode, your score is also the count of correct answers within 60 seconds.
Desktop: Click and drag to rotate the globe. Use the scroll wheel to zoom in and out. Click on a country to select it as your guess. Alternatively, type a country name in the text input and press Enter or click the Guess button.
Mobile: Swipe to rotate the globe. Pinch to zoom. Tap on a country to guess it. Use the on-screen keyboard to type country names.
Keyboard shortcuts: Press Escape to exit a game and return to the menu.
Explore mode: Click the Explore button in the menu to hover over countries and see their names, flags, and continents without playing a game. This is great for learning.
Fullscreen: Click the fullscreen button (⛶) to play in fullscreen mode for a more immersive experience.
Hints help you find countries when you're stuck. Their behavior depends on the game mode:
Beginner mode: You start with 3 hints per round. Each hint highlights a neighboring country on the globe with a pulsing animation. The continent name is also shown. You earn bonus hints every 5 correct streak.
Normal mode: The first hint reveals the continent. Subsequent hints highlight neighboring countries. You have 3 hints available.
Hard, Blitz, Marathon, and Daily modes: No hints are available. These modes test your pure geography knowledge.
Each hint used reduces your score by 2 points for that round.
Yes! JoJio is fully responsive and works on smartphones and tablets. The layout automatically adapts to smaller screens with the globe on top and the game panel below. Touch controls let you rotate the globe with swiping, zoom with pinch gestures, and tap countries to guess them.
The game requires WebGL support, which is available in all modern mobile browsers (Chrome, Safari, Firefox, Edge).

JoJio is built with modern web technologies:
Three.js — A powerful 3D graphics library for rendering the interactive globe using WebGL hardware acceleration.
TopoJSON — Compact vector map data from the world-atlas dataset, providing country boundaries at multiple resolutions.
Earcut — A fast polygon triangulation library used to render filled country shapes on the globe.
Custom Shaders — GLSL vertex and fragment shaders create the Fresnel atmospheric glow, country highlighting, and distance line effects.
Web Audio API — Generates sound effects programmatically (correct/wrong tones, streak celebrations) without loading audio files.
CSS Container Queries — Enables responsive layout that adapts to the globe container size rather than just the viewport.
JoJio renders a real-time 3D globe with country borders, highlights, and visual effects. WebGL (Web Graphics Library) enables hardware-accelerated 3D graphics directly in the browser, which is essential for smooth globe rotation, zooming, and interactive country selection.
WebGL is supported by all modern browsers including Chrome, Firefox, Safari, and Edge on both desktop and mobile. If WebGL is not available, the game will show a loading error.
