Start with licensing, in this order of priority: verify the license number directly on the regulator's own public register (see our guide on spotting a fake license) before looking at anything else. A casino can have great reviews and still be running on an unverifiable or expired license — this check takes under a minute and rules out the worst-case outcome immediately.
Next, look past marketing claims to real, published withdrawal-speed data. Independent complaint-tracking sites and forums (this site's own Complaints section works the same way) show actual resolved and unresolved withdrawal disputes rather than a casino's own "24-hour payouts" banner — a casino's real-world payment record is a better predictor of your experience than anything on its homepage.
Finally, read the specific bonus terms before opting in, not just the headline percentage — use the wagering-requirement math from our bonus guide to work out what a bonus actually costs to clear. As a last practical step, check whether the casino participates in a real self-exclusion and deposit-limit system required by its home regulator (Germany's OASIS/LUGAS combination, described in our country guide, is a strong example of what a serious operator supports) — participation in mandatory player-protection infrastructure is a solid, verifiable signal that a license isn't just a formality.
