On desktop, check that Mini Metro is able to get through your firewall and anti-virus software. The game needs to make a request to this website (https://dinopoloclub.com).
On iPhone and iPad, this means Game Center isn’t starting up correctly. Try logging out of Game Center and back in again. You can do this in the Game Center option of the Settings app.
The Steam Overlay often causes this problem. To disable the overlay for Mini Metro, right-click on Mini Metro in your Steam library. Select Properties, uncheck the Enable the Steam Overlay while in-game checkbox, click Close and try starting the game again.
When an update to the Windows, macOS, or Ubuntu version is available and requires you to download the update manually, the game will notify you when it starts up. How you go about updating depends on how you bought the game.
Humble: This covers anyone who bought the game in a bundle, through the widget on our website, or through the Humble Store. If you added the game to your Humble Library, log in to your account and download the game again. If not, follow the link in the original confirmation email you got from Humble (it’ll look something like https://www.humblebundle.com/?key=xxxxxxxxxxxxxxxx). If you can’t find that link, get in touch using our Support Form, with as much information as you can (preferably the order email or Amazon or PayPal invoice number) and we’ll do our best to dig up your order details.
GOG.com: Either download the update from GOG.com, or download the update through the GOG Galaxy client.
Updates are automatically downloaded and installed if you bought the game on Steam, the Mac App Store, or Origin.
If you purchased the game through another storefront, download the new version from that same storefront.
A Windows 10 update in November 2017 introduced issues into many games built in Unity (including Mini Metro) on some computers when combined with GPU aspect scaling. The only way we know to resolve this is to disable GPU aspect scaling.
NVIDIA: Open the NVIDIA Control Panel. Under Display, select Adjust desktop size and position. Select No scaling for each display.
AMD: Open the AMD Catalyst Control Center. Under My Digital Flat Panels, select Properties. Uncheck Enable GPU up-scaling under Image Scaling Preferences.
This problem can most often be fixed by upgrading your graphics drivers to the latest version.
You can find driver updates here for Intel, AMD or NVIDIA .
This most often occurs with the Asus Xonar sound card. Try disabling “GX” mode in your audio control panel.
For some reason Unity is unable to play any sounds if you’re running certain audio enhancement tools, such as the following:
- Sonic Sound 2
- Sonic Suite
- Razer Chroma
If you have any of these applications running, please terminate them from the system tray and try starting Mini Metro again.
Try setting default-fragment-size-msec = 5 in PulseAudio’s daemon.conf.
This is caused by the Unity webplayer preventing Unity games from starting. Close all open browsers and start Mini Metro again.
This can be resolved by disabling any other displays, starting the game up, exiting, then re-enabling your other displays.
Please note that we can only support Ubuntu 12.04+ as that is the only Linux distribution that Unity builds for. You are welcome to try it on another distribution, and it may work, but if not you may have to claim a refund.
This is likely caused by the wrong resolution being selected. Run the game with the launch parameter -show-screen-selector and select your monitor and resolution.
If the problem you’re experiencing isn’t listed here, don’t panic! You can get in touch with us and we’ll help sort you out. We’ll need a few things though:
A copy of the log.
Make sure that you get a copy of this before you start playing again, otherwise it will be overwritten. This is found in different places based on your operating system:
On Windows, the log is C:\Users\username\AppData\LocalLow\Dinosaur Polo Club\Mini Metro\output_log.txt
If you’re running an old version of the game on Windows, browse to the folder that you extracted it to. The log is in the Mini Metro_Data folder (or MiniMetro_Data for very old versions), called output_log.txt
On macOS, the log is ~/Library/Logs/Unity/Player.log
If you bought the game on the Mac App Store, the log is ~/Library/Containers/com.mpdigital.MiniMetro/Data/Library/Logs/Unity/Player.log
On Ubuntu, the log is ~/.config/unity3d/Dinosaur Polo Club/MiniMetro/Player.log
A description of the problem.
We can tell a lot from the log but it is still helpful getting a full run-down on what exactly the problem is, what you were doing when the problem occurred, and (if it wasn’t a crash) what happened afterwards.
Of course this won’t be much help if it’s for a crash! If the game locks up, or just does something unexpected, then a screenshot can really help.
For help taking a screenshot, browse to http://www.take-a-screenshot.org.
