Are Google Drive saves supported?

Yes. It is possible to save your Sid Meier's Railroads! game to the cloud for use on other devices. To enable cloud saves:

1. From the Main Menu tap the Options Cog → Advanced Options → Sign in to Google Play
2. Once signed in, ensure that Sync saved games via Google Drive is enabled

To sync cloud saves to a different device:

1. Repeat the steps above on a different Android device
2. Relaunch Sid Meier's Railroads!

You will be prompted to synchronise your cloud saves, which will allow you to access them on the second device.

Please note: When not connected to the internet, you may play Sid Meier's Railroads! in offline mode. When you are next online, you may either sync your local save files to the cloud, or overwrite them with your existing cloud saves.

If any local files are deleted while in offline mode, they will be automatically redownloaded from the cloud when next online.
