spinner_crSrLong time lurker here, so here is my short checklist for choosing a casino site. After getting burned once or twice I stopped going by ads alone.
I always start with licensing: see which authority is listed in the footer, and whether they actually accept players from your country. Then payments: card, e-wallets and bank transfer should all be there, and cashout times should be listed up front.
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 good recent review that covers all of this is here [url=https://admin.phacility.com/F644057]official site[/url] and it saved me some time.
Most of my sessions are on mobile, and a good site loads fast and does not log you out every five minutes. Ask support one simple question first: if they answer in a couple of minutes that is a good sign.
That is about it. Set a budget and stick to it.
