spinner_paSrBeen reading this board for a while, but I figured I would share what I look at before signing up anywhere. After getting burned once or twice I stopped going by ads alone.
I always start with licensing: find the licence number and look it up, because some sites quietly block certain regions. Then payments: card, e-wallets and bank transfer should all be there, and there should be no weird fees on cashouts.
Bonuses are the tricky part. Wagering of 35x or 40x is normal, and some games count less towards it. A good recent review that covers all of this can be found here [url=https://sites.google.com/view/gamblezen-casino-8340/]Gamblezen Casino[/url] before you deposit anything.
I play almost only on my phone, so I check how the lobby works on a small screen. Ask support one simple question first: if they answer in a couple of minutes that is a good sign.
Anyway, that is my routine. Only play with money you can afford to lose.
