Multi-monitor support

Quick release today. We've just pushed the gamma8 build from test to the default branch; the most significant change is the reintroduction of the Unity configuration dialog. On Windows you can use this to select which monitor to run Mini Metro on.

To bring up the dialog, hold down the shift key when you start the game. Please note all the other settings are ignored, so you still have to change resolution in-game!

FLAC audio

We've just pushed the gamma6 update to the default branch on Steam. The major change is that the audio is now compressed with FLAC instead of Vorbis—as a result, the download is a little bigger, but the audio is slightly higher quality and decompresses much more quickly. This is one of the first changes we've made for the mobile release that's been rolled back to the desktop build.

About This Game

In Mini Metro, you take on the task of designing the subway layout for a rapidly expanding city. Your city starts with three stations. Draw routes between these stations to connect them with subway lines. Commuters travel along your lines to get around the city as fast as they can. Each station can only hold a handful of waiting commuters so your subway network will need to be well-designed to avoid delays.

The city is growing. More stations are opening, and commuters are appearing faster. The demands on your network are ever-increasing. You'll be constantly redesigning your lines to maximise efficiency. The new assets you earn every week will help immensely — as long as they're used wisely.

Eventually your network will fail. Stations will open too quickly. Commuters will crowd the platforms. How long the city keeps moving is up to you.

Key Features

  • Compelling, constructive, hectic, relaxed gameplay. If that makes sense. It doesn't though, aye? You just gotta play it.
  • Three game modes: Normal for quick scored games, Endless for stress-free sandbox play, and Extreme for the ultimate challenge.
  • Eleven real-world cities to design subways for (London, New York City, Paris, Berlin, Hong Kong, Osaka, Saint Petersburg, Montreal, São Paulo, Cairo, and Auckland). Each has a unique colour theme, set of obstacles, and pace.
  • Random city growth, so each game plays out differently. A strategy that proved successful last game may not help you in the next.
  • Each game's map is a work of art, built by you in the classic abstract subway style of Harry Beck. If you think it's a keeper, save it, tweet it, show it off or make it your desktop background!
  • Soundtrack by Disasterpeace
  • Colorblind and night modes.
  • Trains! Did we mention them yet?


You can check out Mini Metro for yourself and play a game on the London map in the demo. The demo uses the Unity webplayer, so you'll need the Unity plugin (Windows and OS X only unfortunately).

People are calling this game 'Calming,' or 'Zen.' Is it, really? The design is minimalist, and the audio is subdued, and you can pause whenever you want - but all that just disguises what is actually one of the most deviously clever and difficult puzzle games I've ever seen.

So: Stations are little shapes on the map. People show up at each little shape, wanting to go to some other shape. You connect the shapes with metro lines, and a little train will show up to ferry people along the lines you drew to get everyone where they want to go. There's a few more mechanics, but that's 90% of it.

There are only so many metro configurations you can have for any given map, but with every station that pops up, the possibilities increase in number exponentially. There's never quite enough lines or enough carriages or enough tunnels to keep all of your passengers totally satisfied. In essence, playing this game is endlessly performing triage on an ever-growing network that's a few bad decisions away from becoming an unsustainable mess and collapsing under its own weight. It's mind-warping how fast things can get out of hand if you're careless.

Forget Telltale; here, every choice you make feels genuinely heavy and difficult, because they actually are heavy, difficult choices. Crucially, though, there's always a right choice that will keep you alive for at least another week. Every game ends in you frantically trying to fix a bottleneck in your network, or deperately rerouting half your lines to ease up the congestion in one distant corner of your map - and failing. But there's always something you could have done, out of the umptillion different decisions the game threw at you.

This game is terrifying. I've been pulling my hair out. The quiet bleeps and bloops of the passengers arriving and leaving no longer register as something Calming or Zen but as something far more sinister. Needless to say, I absolutely love it.

It's really easy to make a game overly complicated, so it becomes all the more delightful when you come across a simple game with a lot of depth. Every part of Mini Metro is simple and clean, from the concept to the presentation to the mechanics, but the simplicity gives way to moments of intense strategizing.

Each game starts with just three stations, represented as a circle, triangle, and square. You click and drag between them to draw your subway lines, and then watch your little train zip along and pick up passengers of all shapes. Each station generates passengers for the other station shapes, so ideally you want at least one circle, triangle, and square on each line. New stations pop up as time passes, and you have to extend your lines or lay new ones to service them. Your resources are limited, however, generally only starting with three lines and three trains. At the end of every week, you get another train and a choice between two additional resources. These can be more lines, more trains, additional carriages to add to existing trains, more tunnels or bridges for crossing the map obstacles, or upgraded stations for holding more impatient passengers. The game ends if one of your stations hits capacity for too long, which can lead to some panicked re-drawing of lines and dropping of trains.

Actually, it will ALWAYS lead to panic because Mini Metro is insidious in how the scenarios ramp up. Stations pop up in unequal groupings, and unique stations like stars and pentagons can appear in the most awkward places. From your three starting stations the map will explode into a nightmare network of wrong stations in just the wrong spots, forcing re-draws and overhauls of your entire service just to reach that one ♥♥♥♥♥♥♥ station that opened up across the river in the southwest corner. But this explosion will happen so gradually, and accompanied by soothing ambient music and pleasant jingles of services running smoothly, that you almost won't notice until its too late. Like with any good puzzle game there's pressure to perform here, but it's presented in such a way that it causes none of that uncomfortable anxiety that trying to form a clutch tetris or landing that last bubble in Puzzle Bobble does. It's a fun challenge through and through, one that never gets old or tiring.

There are eleven different maps to play on right now, with each having a different layout of obstacles, different layouts of stations, and different capacities for stations. Paris and New York play very differently, for example, with Paris having a lot of tightly-clustered stations with low capacities, while New York has them spread far and wide across the boroughs. The game also has daily challenges to compete in, with everyone taking a shot at the same map and station growth patterns. There are two additional difficulties as well if you get tired of the normal game; there's a sandbox mode if you just want to draw pretty lines and work on efficiency, and an extreme mode where you cannot redraw existing lines, which makes me sweat just thinking about. If you're into achievements, they've got some good ones to keep you playing. Each city has a basic competency achievement, and then one that requires a specific challenge condition, like moving 1200 people around London using only one tunnel. If you enjoy the basic puzzling offered here, there's dozens of hours of it to be had.

I like puzzle games well enough, but few have sucked me in like Mini Metro. The genius presentation using the clean subway map style makes it easy and inviting to work with. And while it certainly doesn't have the complexity of something like Transport Tycoon or Cities in Motion, I find it scratching the same itch in how well it abstracts the subway systems for each city. For fans of puzzle games this one is a no-brainer, and even if you're looking for something more on the management side, there's something to be said for Mini Metro.

The premise of this game had me intrigued as I am curious about how metro systems around the world are designed. I though that I was getting a sim-style game that would let me lay out a metro system in meticulous detail, but this isn't the game that I was looking for. I do enjoy the game, but it is a real-time puzzle game, and not a sim.

There are many cities that you can play in, and each starts with three stations of different shapes - a Circle, Square, and Triangle. A station's shape determines the destination of/number of passengers that will spawn there. For example, Circles will spawn the most riders, but few passengers from other stations will want to go there. A station spawns riders in the shape of the station that they wish to go to, and each passenger boards trains that can take them to one of their destination type, and not a specific station. Your score is the number of total passengers delivered to their destination.

Stations spawn periodically and connecting lines to them so that passengers will get picked up in a timely manner before the stations get overcrowded is the goal of the game. In addition to the three main shapes, several unique shapes can spawn as well, which ups the difficulty quite a bit. Passengers choose trains intelligently, so not always by the shortest route, but the one that will likely take the least amount of time.

Each "week" you get a new train and another random reward that could be a carriage (more passengers for a train), tunnels (the number varies), a new line (there is a maximum number of lines on each map, and you always start with three), or an interchange (increases the number of passengers a stop can handle before overcrowding).

You get visual and audible warnings when a station start to get overcrowded, and if the problem isn't resolved in about 45 seconds, the game ends. So planning ahead is vital, but you can't always do that due to the random nature of the station spawns. Sometimes you'll have a nice mix of stations along each line, and can get quite an impressive score. Other times you'll have eight Circle stations isolated from everything else and only one or two lines to service them, which is usually not enough.

Games last anywhere from a few minutes to 30, and scores range from 200 to 2000+, depending on the map and the luck of the spawns. I recommend the game, but it can be frustrating when you have a good game going and three or four Circle stations spawn in inconvenient spots and ruin it. Still, it's great for when you have 10-20 minutes and not too taxing on the brain.
