Been reading this board for a while, so here is my short checklist for choosing a casino site. After getting burned once or twice I stopped trusting the big banners.
First thing is the licence: check who regulates the site, and if your country is on the allowed list. After that I look at banking: 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. Read the wagering and the max bet rule, and the bonus usually expires in a week or two. A decent independent write-up with the current terms is worth a read here [url=https://pbase.com/solkrypto43b1c0/craybetrealmoneygaminginffd445]Craybet bonus[/url] and it saved me some time.
On mobile I mostly use the browser version, so I check how the lobby works on a small screen. Ask support one simple question first: if they answer in a couple of minutes that is a good sign.
Anyway, that is my routine. Treat it as entertainment, not income.
