## What is MapDeQuiz?

Learn the countries of the world on a map. From country shapes, flags and capitals to rivers, mountains and World Heritage sites, 22 quiz types make world geography fun to learn. Available in English, Japanese and Traditional Chinese, for everyone from students studying geography at school to adults relearning it and travelers preparing for a trip.

WORLD COUNTRY QUIZZES
- Shapes: guess the country from its outline alone
- Find on the globe: spin the globe, find the country and tap it
- Size comparison: compare true sizes that are hard to judge on a flat world map
- Thematic maps: work out what a map colored by population or GDP is showing
- Flags, capitals, neighbors, ranking by size, which is farther north, and more
- Locations of rivers, mountains, lakes, national parks, World Heritage sites, mountain ranges and deserts

Choose the range (world, by continent, or Japan), the difficulty and the number of questions. When you check your answers, the map moves to the correct country and highlights it, and you can look up each option online and on the map right away.

ATLAS
View the world as a globe, an atlas or a flat map. Tap a country to see its capital, population, area, GDP per capita, currency, languages and time zone. Switch to maps colored by population or GDP.

RECORDS
Countries you have learned are colored in on the world map. Countries you missed are collected so you can review them together.

JAPANESE GEOGRAPHY TOO
Quizzes on Japan's rivers, mountains (the 100 famous mountains of Japan), lakes and national parks are included.

PRO (ONE-TIME PURCHASE)
A single purchase unlocks the following for good. It is not a subscription.
- Questions limited to a continent or to Japan
- "Normal" and "Hard" difficulty
- Repeat only the countries you missed
- Sets of 20 questions at a time
- Atlas layers for Japan's national parks, 100 famous mountains, 100 famous castles, hot springs, lakes, traditional dishes and places linked to historical figures
- Ancient sites and historical events in the atlas for every era
- Atlas layers for World Heritage sites, famous landmarks and architecture, national parks of the world, famous waterfalls and US state capitals
Without Pro, every quiz type can be played with the world range on "Easy" difficulty. Country data, terrain, oceans and climate zones in the atlas are available to everyone, as are the "Prehistory and ancient civilizations" and "Early modern" eras of historical events. Pro also removes ads.
