Game Invites and App Notifications
Don’t want to see these anymore? Then this is for you.
App notifications and game invitations are on. By disabling app notifications and game invitations you will no longer see app-related requests sent by your friends. This will not affect your ability to use apps or play games.
Go to your Facebook settings on your desktop and then go to Apps. Where it says ‘Apps, Websites and Plug-ins Lets you use apps, plug-ins, games and websites on Facebook and elsewhere. Enabled.’
Click the EDIT button and click Turn OFF.
That’s it you’re done and will no longer receive App notifications and game invitations.
