City street geography games
The world map is only the start. Corto's City Streets mode drops you inside a single city, where you tap streets, canals and squares by name. Nine cities are live, from the A10 ring to the Périphérique to the Anello Ferroviario, and every question carries a recognition tier so a weekend visitor and a lifelong resident both get a game worth playing.
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.
