Been reading this board for a while, thought I would drop my short checklist for choosing a casino site. After a few bad experiences I learned to read the small print first.
First thing is the licence: find the licence number and look it up, and if your country is on the allowed list. Next come deposits and withdrawals: crypto is a plus but not a must, and there should be no weird fees on cashouts.
Never judge a site by the bonus alone. Anything above 40x rollover is a red flag for me, and some games count less towards it. A good recent review that covers all of this is here [url=https://www.efunda.com/members/people/show_people.cfm?Usr=martinez0aeeb3]bonus bij Superbet[/url] and it saved me some time.
On mobile I mostly use the browser version, and if there is an app I make sure it comes from the official page. Test the live chat before depositing: if they answer in a couple of minutes that is a good sign.
Hope this helps someone. Set a budget and stick to it.
