Been reading this board for a while, so here is my short checklist for choosing a casino site. After a few bad experiences I stopped trusting the big banners.
I always start with licensing: check who regulates the site, and if your country is on the allowed list. After that I look at banking: card, e-wallets and bank transfer should all be there, and the withdrawal limits need to be written clearly.
Bonuses are the tricky part. Anything above 40x rollover is a red flag for me, and live tables often do not count at all. A good recent review that covers all of this is here Ice Casino before you deposit anything.
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.
That is about it. Treat it as entertainment, not income.
