Apart from that, there are some casino sites that provide video guides for beginners, among which sportbet.one is one and I think that's really shows their professionalism.
Just as you mentioned that some casino users who are new are lazy to explore, there are also casino users who are lazy to read guides and watch tutorial videos, they just end up skipping all those parts and want to hurriedly use services and play games that they do not understand. Majority of this people are the ones who end up with complaints sometimes.
If there's a good attitude towards reading and watching tutorial guides, many new gamblers will not experience some problems that they end up experiencing with gambling platforms, or have some complaints about casinos that they end up having.
