Random Passport is a free browser game about the parts of South Korea that rarely make it into travel guides. Every flight drops you into one of the country's 3,558 administrative neighborhoods, picked at random. It might be a busy city dong, a market town (eup) or a farming township (myeon). You see where you landed straight away, look around in street-level photos, read a few notes about the place and collect its passport stamp.
You don't have to guess anything and there is no score. The fun is the landing itself. One flight puts you in a fishing village on an island in the Yellow Sea. The next one puts you in a new apartment district at the edge of Seoul. After a few flights you know Korea better than most guidebooks do.
The full rules are on the how to play page.
South Korea is divided into provinces and metropolitan cities, then into cities (si), counties (gun) and districts (gu). The smallest unit with its own community office is the neighborhood. City areas are split into 2,155 dong. The countryside has 237 eup, which are towns, and 1,166 myeon, which are rural townships. In Random Passport each kind has its own stamp shape: a circle for a dong, a rounded square for an eup and a flower for a myeon.
These 3,558 neighborhoods are home to 51,082,431 registered residents (resident registration, September 2026). The busiest is Mulgeum-eup in Yangsan-si, with 117,251 people. The quietest is Geunbuk-myeon in Cheorwon-gun, with just 87. A random flight is much more likely to land in a farming township than in downtown Seoul. That's why the game feels so different from a normal trip to Korea.
Each region page lists its cities and counties. You get the landmark stamp, local food and festivals for each one, and a link to every neighborhood.
