What Fathom is
Fathom is a geography learning game built around quizzes on an interactive 3D globe. It covers countries, cities, landmarks, and other geography topics, with answers entered by selecting a location, choosing an option, typing a response, or estimating distance. Its about page lists 186 quiz packs and more than 7,600 questions across 497+ quizzes. A four-box Leitner system schedules questions for review over multiple sessions. Each question has a written hint, which the page says is translated into all 14 supported languages. Progress saves automatically; signing in syncs it across devices and combines it with anonymous progress. Players can take a daily challenge with the same 10 questions for everyone, and use global and per-country quiz leaderboards. Fathom also works offline as an installed Progressive Web App. All quizzes and packs are free without an account. An optional premium subscription removes ads and unlocks detailed stats. The game is available on the web and covers 209 countries.
