Hi, have you already decided on the social casino you plan to sign up with? Personally, I liked Sportzino because they have very knowledgeable instructions for a beginner, including what are sweeps coins. I got them first of all after registration, I think there were 20,000 gold coins and I exchanged them for 500 sweeps because I wanted to try exclusive slots that are only available at this social casino, for example Sportzino Treasure. There are also limited time offers at the social casino, which I keep track of via alerts on my email or mobile app.
