The first post I saw on my Google Plus stream is from “Robert Scoble”, which says “Oh, oh, games just turned on for me.” So I just had a look and find it is on for me too :)
And it shows Angry birds, Dragon Age, City wonder, Diamond Dash, Edge world, Dragons of Atlantis, Bejeweled Blitz,Wild Ones, Zinga poker and Crime city, in which is most of them are addictive games, especially games like angry birds. Most of you may have heard of it before.
Select the games, approve access to your data (like Facebook)
