You can collect Gold Bars every 8 hours with Sugar Drops, sometimes there is no one, otherwise one, up to 5 pieces maximum.
If the sugar drops do not work for you, you have the opportunity to win gold in the community at competitions and price questions, but that's also a matter of luck.
Hello @arwirnrao A Warm Welcome to our friendly King Community
I am sorry to say that I am not clear on your question!! Can you please tell me....
1) Are you asking "how to earn Gold Bars into your game"?
2) OR did you make a purchase and have not received the Gold Bars into your game?
3) OR did the Piggy Bank disappear from your game and you are asking for that?
