How do I remove an app or game that I've added? in facebook !!!!!

To remove an app or game you've added:

Click  in the top right of Facebook and select Settings

Click Apps in the left column

Hover over the app or game you'd like to remove and click x

Once you’ve removed the app or game, it should no longer post to your Timeline. If you still see a past story, you can remove it.

Note: The app or game may have stored info from when you were using it, but you can contact the developer to ask that they delete any info they may still have.
