The latest FB game that I played was Gardens of Time which I only joined when my co worker, which happened to be one of the boss invited me to join and ask me to exchange gifts and share energy points to run her time machine. Other friends also ask me to join popular games like Crime City, City Ville, Empires and Allies, etc, etc.
Facebook gift requests and it takes so much time to accept gifts and neighbors. As of now, I have 109 Game Requests and my deep apologies for not responding to all of it.
Good thing I came to know FB GiftAuto that accepts the most played FB games and gift backs to friend. This is downloadable for free and can handle up to 100 FB requests!
Problem solved. =)
