lots of paid apps use license verification. that needs google play services on the phone, and a logged in google account that has the license.

often its possible to patch out license verification. the lucky patcher app can do this automatically in some cases, but I don’t recommend it actually because even I’m not confident what is the real official download site of it. it has features for rooted phones, but it can do some things without that too, by just patching the app.

but if the game is multiplayer, chances are that the servers will attempt to verify with google that you have a license, so that may not be possible
