title: QuickGame in google play games multiplayer - necessarily inside my google circle?
body: <p>Does the <a href="https://developers.google.com/games/services/android/realtimeMultiplayer#quick_game_option" rel="nofollow">quickgame</a> option, in the multiplayer google play games, match random players who are in (i) one's google plus circle or (ii) any online player.</p>
  
  <p>I want to implement quickgame with anyone who is online, and I could not find anything in documentation or elsewhere that clarifies if a "random player" can be outside my circle.</p>
  
  <p>Thanks</p>
