A place appears
A city, a volcano, a stadium, a flag. Each pack 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.
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 packs 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 pack without owning it.
Fans prove it
177 packs 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 packs, 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 that grows with every game you finish, wherever you play. It unlocks nothing, because packs 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 packs. 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. ›
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 packs carry translated names and descriptions, and in the free learning packs 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 pack 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.
