Yes, I can help you without any problem, once you’ve downloaded the .apk file of the game, you need you open the download folder of your browser (Chrome, Firefox, Brave, etc) and after that you will find the game file.
Finally, once you’ve located the file, open it, and depending on your mobile device will request permissions to install games from unknown sources, turn on that option, and try to open again the file and the game will start installing as other apps from the PlayStore, an icon will appear (as other apps) and that would be all! Open the game and enjoy!
I know it might sound complicated but isn’t, it’s simpler that it seems, if you have any doubt or something wasn’t clear at all, please don’t be shy on making more questions!
