A place appears
A city, a volcano, a stadium, a flag. Each quiz asks the world in its own way.
Tap the map
One tap on the world map. You have 10 seconds. The clock is already running.
Score the tap
Up to 1,000 points per question. Accuracy times speed, judged against the map you're on. Smaller maps demand sharper aim.
Light up your world
Home is a globe, and every place you get right lights it up: in any quiz, the Daily or a multiplayer game. A country turns pale green with your first place there and full green at 10 places, or the moment you name it.
Your places raise your level. NEXT shows which country to turn green next, and a tap on any country shows its quizzes. Your globe syncs through iCloud, so your iPhone and iPad show the same world.
One map. Every age.
Corto has one mechanic and four reasons to play it. Nobody has to learn controls, read rules, or make an account. The map is the one interface every generation already knows, and knowledge beats reflexes, so grandpa wins sometimes.
Kids learn it
Classic topography as a game. 10 free Learn quizzes cover the countries, states, and provinces school asks for, and every wrong tap shows the right answer.
Friends battle it
Head-to-head: Blitz, Quick or Classic. Same questions, same clock, no excuses. Invite anyone: they can play your quiz without owning it.
Fans prove it
177 quizzes test what you're obsessed with. Wine regions, F1 circuits, WWII battlegrounds, the streets of Amsterdam.
Grandparents stay sharp
Two minutes, one tap, no ads. A daily workout for your inner atlas, and a turn-based duel the grandkids can't win on reflexes.
See it in motion
Then go and look at it
Get a landmark right and you can fly down to it. Explore drops you into a tilted 3D view of the real place, with a line about what you are looking at. It is the moment the answer stops being a dot on a map.
Available on 113 quizzes, from castles and bridges to airports and city streets. Off by default on older phones, and a single switch in Settings either way.
Climb the ladder
Underneath it all you also carry a level, and every place you get right raises it, wherever you play. It unlocks nothing, because quizzes are the only thing you ever buy.
On your Home Screen
Why it sticks
Per question. Long enough to think, short enough to hurt. Every round is under two minutes.
Themed map quizzes. Capitals and cities, flags and airport codes, volcanoes, wine regions, WWII battlegrounds.
Head-to-head multiplayer. Challenge a friend, trade turns, settle it on the map.
One five-question round a day, the same for everyone. One try, then share your grid and check the Daily leaderboard. ›
Places to find, from world capitals to the streets of Amsterdam. Every question is a different point on the map, so no two games are alike.
Your world, on every device
Corto plays in English, Dutch, German, French and Spanish. Not just the buttons: all 177 quizzes carry translated names and descriptions, and in the free learning quizzes the countries, states and provinces are named in your language too, which is the whole point if you are using them for school.
Your records, your ranks and every quiz you have unlocked follow you between iPhone and iPad through your own iCloud account. There is no Corto account to create, no password, and no profile. A new phone or a reinstall picks up where you left off.
