How We Rate Casinos
At Sunbingo, we've developed a comprehensive methodology to evaluate and rate online casinos fairly and transparently. Our expert team assesses each casino across multiple criteria to help UK players make informed decisions. Here's how we rate casinos in 2026.
1. Licensing & Regulation
The foundation of any trustworthy online casino is proper licensing and regulation. We prioritise casinos licensed by:
- UK Gambling Commission (UKGC) - Our top choice for UK-based players, offering the strongest player protections
- Malta Gaming Authority (MGA) - A reputable European regulator with strict standards
- Curaçao eGaming License - While less stringent than UKGC, still indicates regulatory oversight
- Other Local UK Licenses - Alternative regulated options meeting UK gambling standards
We verify all licenses directly with regulatory bodies and check for any disciplinary actions or complaints.
2. Game Selection & Software Providers
A great casino offers diverse gaming options from reputable software developers. We evaluate:
- Slot Games - Variety, themes, RTP rates, and exclusive titles
- Live Casino - Quality of streams, game variety (roulette, blackjack, baccarat), and dealer professionalism
- Table Games - Classic games like poker, craps, and variations
- Software Providers - Partnerships with industry leaders such as Microgaming, Playtech, NetEnt, and other certified providers
3. Bonus Terms & Wagering Requirements
We scrutinise all promotional offers to ensure fairness to players. Key factors include:
- Terms & Conditions - Clarity, transparency, and readability of bonus rules
- Rollover Requirements - Whether wagering multiples are reasonable and achievable
- Maximum Cashout Limits - Whether restrictions unduly limit winnings
- Bonus Eligibility - Geographic restrictions, game restrictions, and withdrawal conditions
- Fairness - Bonuses that offer genuine value rather than marketing gimmicks
