lucky_pfmtBeen reading this board for a while, thought I would drop how I pick an online casino these days. After getting burned once or twice I stopped trusting the big banners.
First thing is the licence: check who regulates the site, and whether they actually accept players from your country. Then payments: I want at least one fast e-wallet option, and there should be no weird fees on cashouts.
The welcome offer is where most people get caught. Wagering of 35x or 40x is normal, and live tables often do not count at all. A useful overview with bonus rules, app info and payment methods is here [url=http://jobboard.piasd.org/author/sebastiancbc19a/]Lottoland[/url] so you know what you are signing up for.
On mobile I mostly use the browser version, and if there is an app I make sure it comes from the official page. Ask support one simple question first: slow or scripted answers usually mean trouble later.
That is about it. Only play with money you can afford to lose.
