axl88 saidIt's really fun. I just epic failed because I forgot to mention that its an application on the iphone/i touch. It's basically scrabbles.
You can also play Words with Friends on Android based phones too
And I just recently discovered that you don't need a smartphone to play it -- you can play the game on your browser if you're logged into Facebook and then at the top of the Facebook search box type Words With Friends and that will bring you to the Words with Friends Facebook App page (for first-time visitors of that Facebook app page, you need to click on the "Like" button on that page to begin playing the game)..
I have a smartphone with the Words with Friends app and if I make moves on the Facebook app for it, it automatically synchronizes those moves with my smartphone's Words with Friends app (and vice versa). Pretty cool
