spinner_vrSrLong time lurker here, so here is what I look at before signing up anywhere. After trying maybe a dozen sites I stopped trusting the big banners.
Licence comes first for me: find the licence number and look it up, because some sites quietly block certain regions. Next come deposits and withdrawals: I want at least one fast e-wallet option, and the withdrawal limits need to be written clearly.
Bonuses are the tricky part. Anything above 40x rollover is a red flag for me, and some games count less towards it. A decent independent write-up with the current terms can be found here [url=https://joy.link/cryptoplaypicks33d7#gambajack-uk]gamba casino review[/url] so you know what you are signing up for.
On mobile I mostly use the browser version, and a good site loads fast and does not log you out every five minutes. Ask support one simple question first: if they answer in a couple of minutes that is a good sign.
That is about it. Set a budget and stick to it.
