Well, most important is, read the terms from online casinos before you start to play. You should read their T&C's PLUS their bonus terms.
Do some research, it is important to play at safe casinos, unfortunatly there are bad apples out there too!
It also depends where a player lives.
Online Casinos have country restrictions, means they cannot accept players from certain countries.
If you have any specific questions, please feel free to ask!
And what i wanna add to Marina's reply :
Casinos promoted here are safe to play at to my best knowledge. Only casino's that are proven safe by a trustworty source are posted here .(correct me if i am wrong Marina.)
I highly recommend Rizk and Vera&John and Casinoheroes all of them have customers interest as their highest priority in my opinion!
Thank you! Yes we do our best to promote only trustworthy casinos.
You may find some casinos which are not ok, but then you will not see this casino name linked! We hyperlink only casino names if they are ok.
(Sometimes members post of course a casino to ask if anyone has experience)
