Where it started
For years, geography quizzes were a constant tab in the background. Sites like Sporcle were great — but they always felt a little dated. The interfaces hadn't moved much in a decade, the maps were clunky, and on mobile they ranged from awkward to completely broken. The experience was functional but never felt modern or satisfying.
The breaking point was realising just how limited the free options were getting. The best tools were moving behind paywalls, and the free alternatives either had one mode, covered a fraction of the world's countries, or looked like they were built in 2009. Geography is a subject that deserves better.
So in early 2026, GeoBlitz was built from scratch — a proper, modern, fully free geography quiz that actually works on mobile, loads fast, and covers all 197 countries. No subscriptions. No account required. Just open it and start playing.
How GeoBlitz works
GeoBlitz runs entirely in your browser using vanilla JavaScript and D3.js, a data visualisation library used to render the interactive SVG world map. There's no backend, no server processing your answers, and no database storing your data. Everything happens locally on your device.
The world map is built from TopoJSON data — a compact format for encoding geographic shapes. Each country is a rendered SVG path element, which means it's crisp at any screen size and can be coloured, highlighted, and interacted with in real time without any page reloads.
Country recognition uses a normalisation system that strips diacritics and maps common alternative names. So typing "UK" works the same as "United Kingdom", "Ivory Coast" is accepted alongside "Côte d'Ivoire", and older names like "Burma" and "Holland" are understood without penalising the player.
All 197 countries are included — not just the large or well-known ones. That means Vatican City, San Marino, Liechtenstein, Nauru, Tuvalu, and every other microstate and island nation is on the map and part of every game mode.
Scores are saved locally in your browser using localStorage, so your personal bests persist between sessions without any account or sign-in. The map data is fetched from a CDN on first load and cached by the browser — meaning subsequent visits load almost instantly.
One thing worth noting: the map boundaries follow the Natural Earth dataset, which is the most widely used open-source geographic data available. Where territory is internationally disputed, GeoBlitz reflects the position of the United Nations — for example, Crimea is shown and treated as part of Ukraine.
All 13 game modes
Every mode tests a different aspect of geography knowledge. Some are about recall, some are about recognition, and some — like Border Chain — are about understanding how the world actually fits together. Here's a breakdown of all thirteen.
Type Countries
The original mode. An empty world map, a text box, and a clock. Type every country you can remember before time runs out. Sounds simple — but getting past 150 without blanking on the Pacific islands is harder than it looks.
Type Capitals
Type capital cities to light up their countries on the map. A great way to drill capital knowledge while keeping the geography visual — you see exactly where each capital sits in the world as you go.
Country + Capital
Enter country–capital pairs in the format "France, Paris". Both must be correct and in order. It's the most comprehensive knowledge test on the site — getting all 197 pairs right is a serious achievement.
Click Then Name
Click any country on the map, then type its name. A good starter mode for building map instinct — you're training yourself to locate countries visually rather than just spelling them.
Click → Name + Capital
Click a country, then enter both its name and capital city. The toughest combined test of map recognition and capital knowledge in one go.
Random: Name It
A random country highlights on the map. Type its name as fast as you can. Countries appear one at a time and the clock keeps running, so accuracy and speed both matter.
Random: Name + Capital
Same as Random: Name It, but you also need the capital city. The most fast-paced of the combined modes — good for players who want to push their capitals knowledge under time pressure.
Random: Capital Only
A country highlights and you only need to name its capital. Sounds easier — until you get Nur-Sultan, Yamoussoukro, or Ngerulmud. This mode reveals the gaps in capital knowledge very quickly.
Click the Country
A country name appears at the top of the screen — find it and click it on the map. Tests pure map recall without any typing. Great for players who know the names but struggle to place countries visually.
Click by Capital
A capital city name appears and you click the correct country on the map. Combines capitals knowledge with map recognition — you need to know both the capital and where its country sits.
Click the Flag
A flag appears — click the correct country on the map. Tests flag recognition and map knowledge simultaneously. Some flags are instantly recognisable; others will catch you off guard even if you thought you knew them.
Guess the Outline
A country's silhouette is shown in isolation — no map context, no surrounding countries. Type its name from the shape alone. At small scales some countries are surprisingly distinctive; at others they're nearly impossible to tell apart.
Name the Flag
A flag appears — type the country name. Pure flag identification without map interaction. Works as a standalone flag quiz and is the fastest mode to play through if you just want a focused flags drill.
Border Chain is the newest and most strategic mode. Two countries are highlighted on the map — a start and an end. Type a chain of countries connected by shared land borders to link them together. You can build inward from either end. The puzzle is complete when your two chains meet in the middle. After each round, you can compare your route against the mathematically shortest possible path.
Daily Challenge and Unlimited mode
Alongside the main game, GeoBlitz has two standalone modes that work differently to the map quiz.
The Daily GeoChallenge presents a single mystery country each day, the same for every player worldwide. Type any country name as your first guess — you'll receive three clues in return: which continent the mystery country is on, the compass direction from your guess to the target, and whether the target comes earlier or later alphabetically. You have six guesses to identify it. The puzzle resets at midnight and your result for each day is saved so you can track your history.
Unlimited mode uses the same mechanic but with a fresh random country every round, so you can play as many times as you like. It's ideal for practising the clue-reading logic without waiting for the daily puzzle to reset. Each round takes about two minutes and is a genuinely different kind of geography thinking — deductive rather than recall-based.
Design philosophy
Three decisions shaped how GeoBlitz was built and they haven't changed since day one.
No account required. Creating an account to play a browser game is friction that serves the platform, not the player. GeoBlitz asks for nothing. Open the link, play immediately. High scores are saved locally in your browser. If you clear your browser data they reset — that's a fair trade for not having to hand over an email address.
No paywalls, no tiers. All 13 modes, all 197 countries, all difficulty settings — everything is free. The game exists to be played, not to funnel people toward a subscription.
Fast and lightweight. GeoBlitz is built with vanilla JavaScript and no heavy frameworks. The map renders as crisp SVG at any screen size. Load times are fast on a good connection and acceptable on a slow one. It works on desktop, laptop, tablet, and mobile — the map supports pinch-to-zoom and touch gestures throughout.
Who plays GeoBlitz
GeoBlitz is used by a pretty wide range of people, which says something about how geography cuts across different interests and contexts.
Students and teachers use it as a study tool — the timed modes create useful pressure for memorisation, and the visual map format is more engaging than a list of country names. Type Capitals and Country + Capital are the most popular modes in an educational context.
GeoGuessr players use it to sharpen the knowledge side of geography — flags, borders, capital cities, and map recall all transfer directly to location-guessing games. Border Chain in particular trains the kind of spatial reasoning that's useful in any geography game.
Pub quiz regulars and trivia enthusiasts use it to drill the specifics — capitals of obscure countries, flags of Pacific island nations, the difference between similar-looking African borders. The Random modes are good for this because they surface the gaps in knowledge quickly.
Curious people use it because geography is genuinely interesting. How many countries share a border with Germany? Which country is furthest from any ocean? What does the flag of Bhutan actually look like? GeoBlitz is a good way to spend fifteen minutes learning something real.
What's coming next
GeoBlitz is actively developed. Here's what's being worked on or planned for future updates.
