I should start by explaining the prerequisites. They'll need an Android device, probably with the right OS version. Maybe Android 5.0 or higher. Then, enabling installation from unknown sources because that's a common issue people face when trying to install APKs. Next, obtaining the APK file. I need to advise them to use a trusted source, even though the user might not know which ones are safe. But I can't recommend any specific sites due to potential illegal software distribution issues, so I'll have to be vague there.
Also, legal considerations. Remind them that distributing the game without official permission might be illegal. So while I can give the steps, I have to be cautious about endorsing this. Maybe add a disclaimer at the beginning.
Then the installation steps. After downloading the APK, open the file via the Downloads app or file manager, tap to install, grant permissions, and complete the installation. Once installed, launching the app and checking if it's unlocked. But maybe there's a catch with older versions, like needing to delete previous versions first. I should mention that they should back up in case something goes wrong.
