Mini Metro is a minimalistic subway simulator. The goal of the game is to connect stations with the limited amount of lines. Each line can connect to as many stations as needed, but the longer the line, the longer it takes the train to travel to all the stations. Each week a new asset is granted to better maximize the amount of passengers you can carry. The game ends once a station gets too full and stays full after a certain period of time. There are eleven cities to play, each with unique obstacles and pace, with each level having three modes: Normal, Endless and Extreme. Growth of each city is random, ensuring that each time the player plays that city, the result is different.
