You can only earn 500 a day from games, but you can earn as much gold as you're willing to put effort in for. Posting on the threads earns you gold. How much is directly proportionate to how long your post is. There's no cap on posting gold.

It would seem hard but its not too bad to be honest. Just post in topics and being literate gives more gold.
