lucky_lamtLong time lurker here, but I figured I would share what I look at before signing up anywhere. After trying maybe a dozen sites 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. After that I look at banking: card, e-wallets and bank transfer should all be there, and cashout times should be listed up front.
Never judge a site by the bonus alone. Wagering of 35x or 40x is normal, and some games count less towards it. A decent independent write-up with the current terms is worth a read here [url=https://guidehub0ef599.omeka.net/items/show/43]Slotshopper[/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. Support matters too: slow or scripted answers usually mean trouble later.
Hope this helps someone. Treat it as entertainment, not income.
