How we review casinos
Each casino is scored out of 10 across trust and licensing, games, bonuses and customer support, with the biggest weight on whether it pays out reliably. You can read the full method on our how we rate casinos page.
- Payouts: how fast and how reliably the casino pays, using our own withdrawal tests where we have them.
- Trust and licensing: who runs the casino, which licence it holds and how it treats players.
- Bonuses: not just the headline figure, but the wagering, maximum bet and other terms behind it.
- Games and support: the size and quality of the game library, mobile play and how helpful support is.
What to check before you sign up
- Your country: make sure online gambling is legal where you live and that the casino accepts players from your country.
- Withdrawal limits: daily, weekly and monthly caps matter if you win big.
- Bonus terms: wagering requirements and maximum bets can make a big bonus worth much less.
- Verification: complete ID checks early so your first withdrawal isn’t delayed.
