Been reading this board for a while, thought I would drop how I pick an online casino these days. After trying maybe a dozen sites I stopped trusting the big banners.
I always start with licensing: find the licence number and look it up, because some sites quietly block certain regions. Then payments: I want at least one fast e-wallet option, and cashout times should be listed up front.
Bonuses are the tricky part. Wagering of 35x or 40x is normal, and some games count less towards it. A useful overview with bonus rules, app info and payment methods can be found here bonus at Trino Casino so you know what you are signing up for.
I play almost only on my phone, and if there is an app I make sure it comes from the official page. Ask support one simple question first: slow or scripted answers usually mean trouble later.
Hope this helps someone. Only play with money you can afford to lose.
