First, hide the games. Forever.
1. Click App Center on the left side of your screen.
2. Click the X next to Play Now on any game.
3. Click Block [game name?]
This will hide all requests from this game no matter who the sender is.
Now, we can hide people who post too much but still remain their friends. There are several options but I am going to focus on the 2 simplest options.
Hide the person completely but remain their friend.
A. Hover (don't click) your mouse over the persons name in your news feed. You should see the screen below.
B. Hover (don't click) over the word Friends and you should see the screen below.
C. Click "Show in News Feed" and the check box will go away. This person will no longer show in your news feed.
Alternatively, you may want to see some of their updates but not completely hide their updates. If you want to do that, click "Settings" just below the Show in News Feed. You will see the screen below.
These 2 tips should make your Facebook experience more enjoyable. If you have a favorite tip or a question, leave it in the comments below.
