Mini Metro is a game about designing a subway map for a growing city. Draw lines between stations and start your trains running. As new stations open, redraw your lines to keep them efficient. Decide where to use your limited resources. How long can you keep the city moving?
Each phase of the game is played over the course of a week, which is tracked in the top-right corner. At the end of each week, you’re given a new train along with your choice of upgrades which can include more tunnels for crossing waterways, an additional carriage for a train, a new metro line, or expanding the capacity and transfer speed of a station.
Which upgrade you choose will depend on your strategy for expansion and your immediate needs for servicing your lines. You can download the game here.
