Meridian is a geography game that teaches you every country in the world, a few minutes a day. You tap the country on the map or type its name, and the game keeps track of what you know and what you keep missing. It feels like a game, and after a week you know more of the map than you did. HOW IT TEACHES • You start with the countries most people half know, then move to the harder ones a few at a time. • Countries you miss come back sooner. Countries you know come back less often. • If you keep mixing up two countries, the game offers a short drill on that pair. • Three guesses on every question, and no penalty for a wrong one. • Typed answers forgive misspellings and accept native names. • Sessions are fifteen questions and about five minutes. WHAT YOU CAN DO • Learn the whole world, or focus on one region and finish it. • Take a Final on any region when you think you know it. • Earn a seal for every region you complete, and see your record for each one. • Keep a daily streak, with shields that cover a missed day. • Lock a country you have mastered so it never fades. • Get one optional reminder a day, at a time you choose. • Progress past countries and learn capitals, flags, and more. FOR KIDS AND CLASSROOMS No ads, no account, no chat, and nothing to buy to learn the countries. It works as a five-minute daily geography lesson for homeschool or the classroom, and kids keep at it because it is a game. DEEP-DIVE PACKS Go inside a single country. The United States pack has all fifty states, their capitals and flags, 109 cities, all 61 national parks, 235 historic sites, 324 tribal lands, 276 wine regions, and 83 roadside attractions.
