Nature geography games
The natural world is the original map. Corto's Nature packs send you to the Ring of Fire, the deepest canyons, the great river mouths and the last wild places. Sixteen packs and well over a thousand landmarks, one simple rule: see the place, tap where it is.
Free to play. Always.
Corto is free to download, and it is not pay-to-play. No ads interrupt you, no energy meter runs out, no lives to wait for. Play as many rounds as you like. World Cities and the learning packs are free forever; the rest are a one-time unlock, never a subscription.

How it works
Every pack runs on the same engine. A place is named, you tap it on the map, and you score up to 1,000 points per question on accuracy and speed. A game is ten questions, two minutes, 10,000 points possible. Play solo, or challenge a friend head-to-head over Game Center. Miss a tap and Corto shows you the right spot, so every round teaches you something.
