Did you know that you can play Vocabulary.com with your Facebook friends? Just look for the Friends tab in the box to the right as you play, and, if you're logged in with Facebook, you'll see a list of your Facebook friends playing, their point values, and where you stack up against them.

Want to invite more friends? Follow the link at the bottom of the Friends tab. Want to learn more about the friends playing now? Just click on any name to go to that friend's profile page. Not logged in with Facebook yet? No problem. We'll prompt you to do so when you select the Friends tab.

Watch this short video for a demo of how this works.
