Flippy - hover over the annoying games and the word "hide" will appear. Click that, and you'll never see that specific game mentioned again. Without this ability I would have quit FB a long time ago.
Not only are the games annoying to everyone that isn't sucked into them, but they are mostly run by one company called Zynga, designed as a
scam, which was outed a while back. I'm really confused how anyone can continue enjoying the games after hearing about that.
