DailyMetro Istanbul

DailyMetro is a set of free browser games, one for each city's transit network, made by Eliott Gandiolle. The Istanbul edition covers the city's metro lines on both sides of the Bosphorus. It opens in Turkish at dailymetro.live/istanbul, and the same game is in English at /istanbul/en.

Each day one station is the answer for everyone, under a day number, and a new one is drawn at midnight Istanbul time. You start with any station and have 8 guesses. Each guess fills a row: the lines your station shares with the hidden one, an arrow pointing toward the answer, whether its name has more or fewer letters, and whether it is in the same district (ilçe), such as Beyoğlu or Üsküdar. 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.

The game is free and needs no sign-up; the Istanbul page carries ads (a bar along the bottom, rails beside the board on wide screens and a small floating video on phones). It suits people who ride the Istanbul metro every day, transit fans, and visitors who want to learn the network one station at a time.
