Gamma 4

We've made a number of small changes and fixes in the build that's just gone live. The most noticeable changes are reduced load times as the game now caches the decompressed audio, and a fix for a long-standing bug in the passenger pathfinding.

Gamma 3 build

Hi all! We've just pushed a bunch of minor fixes out with the gamma3 build, including the following:

  • New audio arrangement for Melbourne.
  • Bridges are now used to cross the Yarra instead of tunnels.
  • Fix for Melbourne's Extreme achievement check.
  • Portrait resolutions are no longer broken.
  • The colour for Cairo's grey line is more distinctive from the unused line's colour.
If you want to know what we're up to, you can always find the list of issues and tasks on our Trello board.

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).

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.

Mini Metro is a line based simulation strategy/ time based subway system. The art style is simplistic, and the gameplay is basic. You are in charge of a city subway system, and are responsible for transporting people from one station to another. You lose the game if you let the stations get overcrowded. The game is time management based, with new upgrades available every week when you successfully complete a week as a reward. There are a multitude of different levels and content, and each map of mission has its own leader-board, which can add to the competitive feeling as you play.

There are daily challenges, which is appreciated, but there is no expected level of completion, such as 500 people transported. This I feel takes away from any incentive a player might have towards these goals. The leader-boards for these challenges show the top 10 people, but don't give motivation or incentive for what you have accomplished on a personal level as games are meant to be personal.

Another aspect that may only appeal to certain players is that the game states directly that you cannot win. There is no end game. The game keeps growing, with new stations, complications, and population, to the point that you will not be able to keep up. You will not be able to grow your subway empire, simply manage the time you have to the best of your capability. If you enjoy time management games, this might be for you; the game is very basic- a simplistic casual game for those who find casual games too demanding.

The game mechanically give you exactly what it promises. For the current asking price of $10 dollars, I cannot recommend it, but if it were on sale, and this type of game appeals to you, then go for it.

Greetings fellow gamers! This is Gamer Guy (In a Suit) from the Echo Army YouTube channel! Today I am bringing you a review of an intriguing little puzzler, Mini Metro. Mini Metro was officially released onto Steam on November 6th, 2015 by Developer/Publisher Dinosaur Polo Club and Publisher AGM Playsim.

(NOTE: This was a review from a game in my own Steam library, it was NOT provided by the Developer and/or Publisher)

Video Review:

The "Too Long, Didn't Watch" Review:

Fantastic little puzzler. The art-style and music are enchanting. Easy to play, hard to master. Addicting 4/5

The "Meat & Potatoes" Review:

I wasn't quite sure what to expect with this little thing. A transportation puzzler. Open and run lines to maximize efficiency. Seems simple enough, right? Especially since this isn't crazy detail, it's just lines and shapes. You get rolling, and there's this catchy, soothing music that gets going along with your lines and station thing you know, you just can't stop! You've got lines going everywhere, you're hoping to level up then dreading the decision of which perk you want (More Tunnels or a Carriage? Another Line or an extra Locomotive?). It can get rather intense on you pretty quickly. There are different levels of difficulty, daily challenges, high scores, scenario unlocks, etc. There is a ton of replayability. The visuals and the music are pleasant, enchanting and beautiful. Very nice touch for a little puzzler, really. I also genuinely thought I would take issue with the $10 price point, but cannot see a problem with that. now It is worth $10. I keep going back. It is nearly impossible to play just one attempt. 4/5 stars for this one, gamers. It's so much fun, once you try it you will get hooked!

Happy Gaming!!!

Ever wondered in your "efficient algorithms" class why you need min-cut, max-flow, shortest path etc?
Mini-Metro has and is the answer!

Highly addictive!

While a simple and easy to understand game, it takes good critical thinking skills and a knack for organization to really master this game. A crisp, elegant design coupled with brilliant, satisfying sounds make this game an addicting pastime. Would recommend
