Receiving game invites or getting Facebook apps a day is really frustrating. In case you possess Facebook account then it is mainly for communicating with friend. If you do not use any apps at all then turn the app or game feature off. This way you would not get any invites from your friends. This also prevents user from utilizing Facebook account to log in to apps. Apps which use Facebook to operate might cease to work after this switch. In order to avoid the issue block games or individual apps. However you can block an app once when it appears in your notifications. You cannot block an app in advance.
