How We Rate Casinos
At Kalai London, our rating methodology is designed to help UK players make informed decisions when choosing an online casino. We evaluate each betting site against a comprehensive set of criteria, prioritised by importance to player safety and experience.
Licensing & Regulation
We prioritise licensed and regulated casinos above all else. We assess whether a casino holds valid licenses from reputable jurisdictions including:
- UKGC (UK Gambling Commission) β the gold standard for UK players
- MGA (Malta Gaming Authority) β widely recognised EU regulator
- CuraΓ§ao eGaming β established offshore authority
- Other local GB-approved licenses
We verify license status directly with regulators and flag any expired or questionable credentials. Unlicensed casinos are not recommended.
Game Selection & Software Providers
We evaluate the breadth and quality of gaming options available, including:
- Slots (classic, video, progressive jackpots)
- Live casino games (roulette, blackjack, baccarat, poker variants)
- Table games (European roulette, craps, sic bo)
- Speciality games (bingo, scratch cards, virtual sports)
We also assess partnerships with leading software providers such as Microgaming, NetEnt, Playtech, Pragmatic Play, and Evolution Gaming. A diverse provider portfolio indicates higher game quality and innovation.
Bonus Terms & Wagering Requirements
We carefully review promotional offers and T&Cs to identify fair and transparent bonus structures. Our assessment includes:
- Clarity of bonus terms and conditions
