Chase Hatchery Group

I need your help! A former colleague gave me a link, and a few weeks ago, I registered for free and tried a few games at the social casino. While I was getting the hang of things, I noticed that I could send someone a referral link to register at American Luck and receive additional sweeps coins casino for doing so. As it turns out, my colleague received them as well when I registered. I didn't even know that existed. How else can I get extra coins? Please share your experience!
