Mostly a reader, rarely post, thought I would drop 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: check who regulates the site, and whether they actually accept players from your country. 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. 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 can be found here [url=https://cryptoplaypicks894151.xobor.de/t59f1736275306-Slott-Casino-Real-Money-Gaming-in-A-Practical-Player-Guide.html#msg6387109]Slott bonus[/url] so you know what you are signing up for.
On mobile I mostly use the browser version, so I check how the lobby works on a small screen. Ask support one simple question first: slow or scripted answers usually mean trouble later.
That is about it. Only play with money you can afford to lose.
