punter_xeorLong time lurker here, so here is my short checklist for choosing a casino site. After trying maybe a dozen sites I learned to read the small print first.
First thing is the licence: see which authority is listed in the footer, and if your country is on the allowed list. Next come deposits and withdrawals: 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 some games count less towards it. A useful overview with bonus rules, app info and payment methods is here [url=https://www.dibiz.com/activation+dbz348aaea316]bonus at Rolletto[/url] so you know what you are signing up for.
Most of my sessions are on mobile, and a good site loads fast and does not log you out every five minutes. Test the live chat before depositing: slow or scripted answers usually mean trouble later.
That is about it. Set a budget and stick to it.
