Zynga soon to launch a new reward related website 'RewardVille'.
Where you can login with your facebook (Zynga) login id-pass to play for awesome rewards. In my opinion this is the developed version of Zynga lotto, which they have launched few month back. In this RewardVille, players from almost all zynga games try their luck for some rewards.
Om my last post i have mentioned the reward up-for-grabs on CityVille Game. About these rewards I have already informed you last year on one of my post. Bookmark this site for the ultimate newses regarding Zynga CityVille.
