Well, that was fast. Just days after announcing its Zynga Platform, the casual and social games giant has revealed Zynga Platform is now available in open beta form. Like, you can go to Zynga.com right now and play some games. As of writing this post, 1.6 million people are currently doing just that.

Some functionality isn't live right now, but if you're a seasoned player, you'll find your progress there waiting for you on Zynga Platform. You can set up a Zynga profile, add some zFriends (ugh) and chat, and play any of the five games available: CastleVille, Words with Friends, CityVille, Hidden Chronicles and Zynga Poker.
