How can you get free star coins on star stable?
You can not get free Star Coins, not that I know of at least. If you are Star Rider or Lifetime Rider you get one hundred Star Coins every Saturday.
There's Star Doll and AllGirlArcade. Both can be free unless you want the exclusive things. Star Doll is where you dress-up famous people. You can make your own account where you have a house and can design clothes. On AllGirlArcade you play games to earn Star Coins and buy clothes and furniture that you can.
How do you get to the settings on star stable I'm trying to change servers to meet up with my friend?
By beating every island every time you beat a island you get 100 free coins and a medallion! If you go to the bottom right it says "SAVE" and you get a free 25 coins when you put in a username and password! if you put in a parent email address you get a free 50 coins! that's how you get coins in poptropica
