Watching ads and other ways of earning gems

[LemracCafe]

I see sometimes that some players watch ads to earn gems, how does one access this features? Also often in the "to do" list message to install other S8 games and earn gems, but error message saying that game not available in my country. Are there other ways of accessing these features?

There are loads of ways to earn free gems in game. The Inventory Guide is the best source to look at, but there is also a dedicated information nugget on gems too.
