Too often it locks up during the Word Rivals mini game. Not sure if this is due to the other person leaving or what, but it just sits there with the timer at 0 and never gives me my turn. I've waited 10 minutes before just to see if it would eventually work, but nothing. If I leave, it considers it a forfeit, I don't get the win (or the 1 star for a loss), and it keeps my ticket.
