DailyMetro Seoul

DailyMetro is a set of free browser games, one for each city's transit network, made by Eliott Gandiolle. The Seoul edition covers Seoul subway lines 1 to 9 and opens in Korean, with an English version at its own address.

Each day one station is the answer for everyone, under a day number. You start with any station you like and have 8 guesses. Each guess fills a row: the lines your station shares with the hidden one, an arrow saying which way the answer lies, whether its name has more or fewer letters, and whether it is in the same district (gu). Green is a match, orange is close and red is a miss. At the fourth guess the game shows you the answer's line, and a button lets you give up and look at the map.

Before the first guess you choose Normal, with letter, district and hint clues, or Connoisseur, which trades them for the opening year and passenger traffic and gives no hints. Beside the classic game, the Map mode asks you to place the day's station on the network and the Photo mode shows a station entrance to name. A streak counter, statistics and past days are kept in the browser, with no account.

It suits people who ride the Seoul subway every day, transit fans, and visitors who want to learn the network one station at a time.
