Deleting a game from my phone entirely

I need to uninstall and delete my account from a couple of games. I have installed on my phone in order to start them over again because there’s many sites now that will pay you for these games, but they pertains to new users only and they have a way of knowing that you have had that game installed on your phone or attached to your email address in the in the past, however I have noticed that when I ask for a full deletion of all my account from the game before I uninstall it on some of them, I can reinstall them later and it’s it works just wondering if anybody knows of an easier way or a different kind of way around it
