Golden Spins can be reached by clicking the Hamburger menu in the top right corner and clicking on the "Daily Spin" button.

You are given a free daily spin every 24 hours.  Simply click the wheel to spin and you should receive whatever prize the wheel stops on. 

After your free daily spin, you will need Golden Spins to continue spinning the wheel. 

Golden Spins can be claimed as rewards in events, purchased in the Shop, or found in Daily Deals.
