Been reading this board for a while, so here is what I look at before signing up anywhere. After trying maybe a dozen sites 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. After that I look at banking: I want at least one fast e-wallet option, and cashout times should be listed up front.
Never judge a site by the bonus alone. Anything above 40x rollover is a red flag for me, and the bonus usually expires in a week or two. A decent independent write-up with the current terms can be found here [url=https://forum.thewonderweeks.com/member.php?action=profile&uid=349888]play at Smash Casino[/url] before you deposit anything.
I play almost only on my phone, and a good site loads fast and does not log you out every five minutes. Support matters too: slow or scripted answers usually mean trouble later.
Anyway, that is my routine. Treat it as entertainment, not income.
