There are several ways to get more coins!
You can do this by tapping on the daily spin and collecting additional coins every 4 hours, inviting Facebook friends to join Spades Royale, completing missions or quests, participating in contests, exchanging gifts from friends via the social hub, receiving bonuses from the app's Facebook, Twitter or Instagram page, watching promotional videos* or purchasing coin deals :)
*Please note that the videos are available to our players by a third party that supplies them, and are not always available for all our players at all times. You may watch up to 6 videos a day.
