How do I stop apps I've never used from sending me Facebook notifications?

[errantseagull]

I'm getting notifications from CastleVille, Ravenskye City, and Ravenwood Fair. I've never used these apps, and I don't want notifications. I've been through all of the privacy and account settings and cannot find a way to get rid of these notifications. I tried going to the CastleVille page to block the app, but that just leads me to the game . . .

Click "Account" in the upper right corner of your Facebook page, then click "Account Settings" in the list of options that appears. This takes you to a new page.

Click the "Notifications" tab on this new page. This takes you to a list of notifications that you can choose not to receive.

3
Click the boxes beside any of the notification types for which you are receiving unwanted notifications to remove the check mark in the box. The types of notifications include various apps, being tagged in a picture, new friend requests, comments on your videos and many more.

Click the "Save Changes" button when the only notification types checked are ones for which you wish to receive notifications.
