The popular Match 3 title Zuma's Revenge is currently available for free on Origin.
I don't really have much to say about this game. It's not a bad title, but perhaps I wasn't really in the right mood to enjoy it this episode. There's a number of new features and tricks added that make this more enjoyable than the original Zuma, such as the leaping ability and variety of shots. It's not my favorite Match 3 game though - I personally prefer Bejeweled or Ironcast.
