punter_xhorLong time lurker here, thought I would drop what I look at before signing up anywhere. After a few bad experiences I stopped trusting the big banners.
First thing is the licence: find the licence number and look it up, and whether they actually accept players from your country. Then payments: card, e-wallets and bank transfer should all be there, and the withdrawal limits need to be written clearly.
The welcome offer is where most people get caught. Read the wagering and the max bet rule, and the bonus usually expires in a week or two. A useful overview with bonus rules, app info and payment methods is here [url=https://www.articleted.com/article/1249730/427726/a-practical-guide-to-reveryplay-for-smart-players-in-2026]ReveryPlay[/url] 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. Support matters too: 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.
