Ive been downloading games that says that is compatible for android but my main problem is that the files im downloading are zip/7z or even rar, even if i extract the files i couldn't fine a way to run the game its frustrating
Either extract the files with 7zip/WinRAR on your PC and then transfer them to your phone, or download the RAR app and extract the files using the app.
Extracting 7zip/RAR files without one of these two apps usually results in an incomplete extraction.
