You can collect the Daily Bonus the first time you play each day. You can find it every day under the "Rewards" tab in the Inbox.

You can also collect Free Coins more often by tapping the FREE COINS button in the lower right corner of the Map or Club screens. Watch the timer to see the next time you can collect.

By the way, if you're looking for MORE freebies, head over to the TriPeaks Shop and grab your Gift of the Day!
