Android Versions DA, SITA, RMA Available here

Here are the four latest Android versions of the games. 

There are many ways to install APK files on android devices, and it depends on your device.

The easiest is when you click to download an APK file, you will see a notification right after downloading an APK file, and simply tapping that notification should start the install process, prompting you for permission to install.

If that is not available, you’ll need to make sure that your phone has permission to install third-party apps. You can make sure this is checked under the “Security” tab or listing within your Settings menu. Normally it’ll say allow third-party installations or install from unknown sources, but some newer phones and versions of Android are a little more granular. 

You’ll have to pick which apps are allowed to install unknown sources, which is generally going to be your preferred browser.

The most secure way is to download the APK file and save it to safe place on you phone. If you have a SD card, that is a good place to store and install.

Once you’ve done that, you’ll need to find the file and open it to start the install process. Most Android devices have a program called "File Manager" or "My Files".  If you don’t have one or just want to use something else, there are plenty of file managers available on the Play Store as well. If you go the file manager route, you might need to back up to the previous step and verify that it’s able to install apps from third-party sources, however.

You can also download an APK file to a PC or Mac, and use a USB cable, or SD card to transfer the APK to your Android device.

If you are still confused, google "loading apk files" and maybe the make and model of your device to get step by step instructions.
