It,s better not to play online casino at all i believe, just because most of the times casino will take your money and don,t give anything back. Of course, you can win something in a single day, but most of the times this game will just eat your money.
I know, some people can,t controll themselves and after poker losses they can go for a casino games in hope to get some money back, but it doesn,t work that they and most of the times it,s ending just with a bigger losses.
So my advice for everyone is just to try to focus on poker and don,t play any other games.
