Welcome to the community of Bitcointalk.org.

But what i found in your free spins offer is a Phone Number verification? what is the  need for this? there are even many casino that starts offering free spins with higher coun asking nothing but to try their site?

you are gathering players here mate so please don't ask for something personal first, let this be in the future though I know that you are only hindering the opportunity of being abused.
