You have to go to settings in chrome and put your device id in that extension. This will show those apps compatible with your phone. (google how to know your device id of your phone with some code). After downloading the apk files move the files to your phone with usb cable, wifi, etc. And in your phone click on that file to install. And now u can use/play that app or game.
Anybody can download apps from play store in Pc. I will explain it very simple. First you should have chrome browser. In that download an extension called apk downloader and enable it. Now in chrome browser go to play store there is a link in every app/game to download or save it.
