# Global Challenge AI > An AI-powered classroom strategy game where students explore world history, geography, and culture across eras — from Nomad to Super-Power. Built for teachers, designed for human intelligence (not to replace it). Created by Lee Chazen. The game uses a Wheel of Knowledge across 13 categories (history, geography, science, culture, language, literature, math, civics, ethics, art, music, current events, and more), a Nation Matrix scoring 13 real-world country attributes, and an AI tutor that gives strategic clues without giving answers away. ## Core pages - [Home / Teacher Hub](https://www.global-challenge-game.com/): What the game is, who it's for, and how teachers run a session. - [The Story](https://www.global-challenge-game.com/the-story): Origin and educational philosophy behind Global Challenge AI. - [Nation Matrix](https://www.global-challenge-game.com/nation-matrix): Live scoring of 195 countries across 13 categories — Land Mass, Population, Literacy, Per Capita Income, Natural Resources, Military Strength, Agricultural Output, Technology, Cultural Influence, Strategic Location, Maritime Trade Access, Governmental Stability, Happiness Index. - [Game Lobby](https://www.global-challenge-game.com/lobby): Set up turn-based or concurrent multiplayer sessions, choose teams, timers, and difficulty. - [Marketplace](https://www.global-challenge-game.com/marketplace): Subscriptions and institutional licensing for schools. - [Prompt Store](https://www.global-challenge-game.com/prompt-store): Curated AI prompts for educators, with revenue split with creators. - [Leaderboard](https://www.global-challenge-game.com/leaderboard): Global rankings by duration, age group, and starting era. - [Testimonials](https://www.global-challenge-game.com/testimonials) - [Awards](https://www.global-challenge-game.com/awards) - [Creations](https://www.global-challenge-game.com/creations) - [Connect](https://www.global-challenge-game.com/connect) ## Key terminology The game uses stewardship language, not conquest language.
