Kartavera

About this game

Most maps lie about size. Mercator makes Greenland look like Africa and Europe larger than life. Kartavera shows every country at its true size — and turns what you see into games you come back to every day.

DAILY GAME
• Ten rounds a day, the same for everyone in the world
• Which country is bigger, who has more people, who lives longer, who is richer
• A flag, a country's shape, a capital, a river or a mountain
• Streaks with freezes, XP and levels, and a leaderboard by player, country and continent

PLAY AS MUCH AS YOU LIKE
• Practice: ten rounds of one thing — flags, capitals, currencies, languages, shapes, area, population, income, life expectancy, forests — for the world or one continent
• Review: the countries you missed come back tomorrow, then in 3, 7, 14 and 30 days until they stick
• Flag Rush: sixty seconds, as many flags as you can name
• Higher or Lower: one country's figure on the table — is the next one higher or lower?
• Weekly challenge: twenty harder rounds, one go, one board for the week

AGAINST OTHER PLAYERS
• Live duels: the same ten rounds at the same moment, points for being right and quick
• Challenges: play now, your friend has 24 hours to beat you
• Weekly leagues from Bronze to Diamond, duel tiers and monthly seasons

A PASSPORT OF THE WORLD
• Every country you answer right gets a stamp
• Badges for streaks, perfect days, whole continents and more
• A profile with your level, streak, rank history and passport map

THE ATLAS
• Every country at its true relative size, on the Equal Earth projection
• Slide from Mercator to Equal Earth to the globe and watch the distortion melt away
• Lay any country over any other place on Earth, at the same scale
• Colour the map by population, income, life expectancy, internet use, forests, CO₂, government and more
• Find countries by what they are: "landlocked monarchies in Europe", "countries that drive on the left"
• Rankings for every figure, for the world and each continent, with sources and years
