How much did you manage to get for the welcome bonus? There, the size of the welcome bonus depends on how many points you complete, for example, I completed all of them and received 630,000 GC and 1,000 FC. In general, free coins are a virtual currency inside Fortune Coins social casino, so you can spend it on playing slots and other games. You can also participate in other tournaments to get more of these coins and, accordingly, try more different slots. I hope I managed to explain to you the whole concept of a social casino.
