So you want to start back from the beginning eh? Well, if you are new to Android and you are wondering how to do that, this post will teach you how.
To start a game back from the beginning, you do not need to uninstall it and then install it again. Instead, you just need to clear the game's data through your app manager.
Now the location of Android's app manager varies in different locations in some manufacturers' phones as they always tend to change the operating system's UI and move some things around. But it really shouldn't be that hard to locate your application manager as it's usually found in Settings.
You just need to lurk a little if you still haven't been there, look for a menu called "Apps", "Application manager", "Applications", etc. Once you go there, you will find a list of your installed applications and the Downloaded applications should appear first.
Below is a sample screenshot of listed apps:
Simply choose the app which you want to reset and it should take you to this screen:
Now start back your app and it will start as it was just installed with all of the settings reset and all of the progress wiped.
