title: Open Graph for iframe app (game)
body: <p>We've created a simple game as an iframe application for facebook and we now want to use OG to make it more interesting.</p>
  
  <p>The game: A user can challenge a friend and they both have to choose a card - in the end the user with the "stronger" card wins.</p>
  
  <p>We don't have a website for this game - it's just the facebook app. We've read that an OG Object has to be represented by an actual object-page: </p>
  
  <blockquote>
    <p>'you will now need to create a publicly accessible web page that
    represents this object using Open Graph metatags.'
    <a href="https://developers.facebook.com/docs/opengraph/tutorial/" rel="nofollow">https://developers.facebook.com/docs/opengraph/tutorial/</a></p>
  </blockquote>
  
  <p>Is this really necessary? And if not, is there any good tutorial or documentation about that?
