Yes, but Words with Friends is superior - if for no other reason than it's the version I prefer. A big group of us play during the day (from my other universe) and the Droid people felt all left out. Just sharing.
Wordfeud is good, but you always seem to either get stuck with really bad letter combos, or playing against someone who insists on playing only 3 letter words. I kind of stopped playing after a while.
