Don't Get It.
I never know when I can get free coins. I just try it and sometimes it works and sometimes it doesn't. Any comments?
caesars casino free coin links are only good for 48 hours. If a post older (2~3 days old) than that it is probably expired.
The share links page also contains wall posts from Facebook friends some of them don't have any free stuff just post for big win or so.. and some has small amount of coins but has very limited amount of clicks before it gets depleted.
