About this game

BrainBorders is a trivia quiz and strategy game where you fight for your country on a shared world map played by people everywhere. Test your general knowledge of geography, history, science, art and culture while you capture territories.

Every battle is 3 multiple-choice questions, 12 seconds each. Pick your difficulty — Easy, Medium or Hard — and every correct answer chips away at the fortress of the territory you're besieging. Bring it to 0 and the territory changes color: it's yours, and your country's.

• A persistent map of ~170 real countries — what you conquer stays conquered
• Represent your real country and climb the weekly country-vs-country ranking
• Defend your territories and repair your allies' walls
• Liberate your occupied homeland for a liberation bonus
• Geography, history, science, art and culture trivia in 6 languages
• Quick 3–5 minute sessions — perfect for any break

Every Sunday the map partially resets and a new weekly champion is crowned. Questions, trivia, quiz, general knowledge, strategy and conquest in one game. Your country is counting on you!
Trivia quiz meets strategy: conquer countries on a world map.

What’s new

More energy to play with! Your tank now holds 8 attacks instead of 5, so you can push deeper into a session before waiting for it to refill. We've also spaced out the full-screen ads so your battles are interrupted less often. Plus smaller fixes and clearer in-game text.
