How We Rate Casinos
At Amarsi Fragrances' Top 20 Betting Sites UK, we employ a rigorous and transparent methodology to evaluate and rank online casinos. Our comprehensive assessment ensures that UK players can trust our recommendations and make informed decisions about where to play.
1. Licensing & Regulation
The foundation of any trustworthy casino is proper licensing and regulation. We prioritise sites licensed by:
- UK Gambling Commission (UKGC) – The gold standard for UK operators
- Malta Gaming Authority (MGA) – Stringent European oversight
- Curaçao eGaming – Established international licensing
- Local GB licenses – Additional compliance certifications
We verify all licenses and check for any regulatory sanctions or complaints. Unlicensed operators are automatically excluded from our rankings.
