Zynga Poker

Zynga is mostly known for making a certain annoying farm game on Facebook, but their Poker game is pretty good (and free too). Once you’ve signed in with your Facebook account you can play Texas Hold ‘Em poker with anyone who is logged onto the service, including your Facebook friends, no matter what device they are using.You get a fair amount of free chips when you sign up and if you keep push notifications on (and use the app every day), you’ll get a daily bonus of $2,000 worth of chips. (Extra chips can be bought with an in-app purchase).
