Long time lurker here, so here is my short checklist for choosing a casino site. After trying maybe a dozen sites I stopped trusting the big banners.
Licence comes first for me: find the licence number and look it up, and whether they actually accept players from your country. After that I look at banking: card, e-wallets and bank transfer should all be there, and there should be no weird fees on cashouts.
Bonuses are the tricky part. Wagering of 35x or 40x is normal, and some games count less towards it. A useful overview with bonus rules, app info and payment methods is worth a read here [url=https://www.codesaya.com/u/csacc4e/]Trino Casino app[/url] and it saved me some time.
Most of my sessions are on mobile, so I check how the lobby works on a small screen. Test the live chat before depositing: a real human reply beats a bot loop.
Anyway, that is my routine. Treat it as entertainment, not income.
