One easy way to get rewards in-game is to watch video ads. You can watch a limited amount of ads every day to collect the rewards, and these rewards come in two forms.
  1. Goldmark: You can earn a certain amount of Goldmark every day from watching ads, and this is one of the most reliable ways to get Goldmark for free.
  2. Premium Membership (of a certain duration): You can earn all benefits of a Premium Membership for a short period of time. This is represented by a black and gold icon with a duration indicator (such as '4 hours'). After watching the ad, the respective Premium Membership time will be added to whatever Premium Membership you have already acquired.
