Golden Bones are the premium currency in Hounds of Fury. You will start off with 30 Golden Bones in your account.
You can view the balance of Golden Bones in your account in the bottom right of the screen, next to your cash balance.
They can be earned by spinning the Wheel of Fortune in game or by purchasing in game (via the Shop).
