@Wrapped_loli - well someone was definitely listening because there is now an episode race that starts every Wednesday when they release the two new episodes and if you are in first place each time you win 5 gold bars  (not sure how many for second place - maybe 3) and third place is 1 gold bar. 

Also there are quite a few opportunities to participate in various contests in the community where you can win gold bars.  The contests are usually tied to a specific game (like Candy Crush Saga or Blossom Blast etc.), but occasionally they  are community wide and you can specify which game you want the gold bars.  For example: Right now for Pet Rescue Puzzle - you just need to post a picture of where you are in the game if you are at 100 or higher you get 10 gold bars and if you are at 250 or higher you get 25 gold bars free!  Have fun and check them out!
