In FC Mobile the classic way to earn gems is by completing daily quests, watching ads or playing events. But there is an alternative method that can allow you to earn large amounts of gems.
I'm talking about the offers available in the store and more specifically about some games that will allow you to get huge amounts of gems.
By selecting your favorite game and completing the various quests, you can earn gems to use to improve your team on FC Mobile.
What you need to know, however, is that during certain periods of the month, the offers are worth double. This means that by selecting a game during a certain period of the month, you can earn double the expected amount of gems.
Below are the dates, unofficial but leaked on social media, of when the 2X offer will be active. Leak and image credits by Sappurit.
The dates indicate the 3 days when 2X will be available (reference time 07:00 UTC). Simply select and start a game for the first time on that date to earn large amounts of gems.
