How We Rate Casinos

At salonguineapig.co.uk, our casino reviews follow a consistent, UK-focused methodology designed for players looking at European betting sites in 2026. We test each operator against eight core criteria below, listed in descending order of importance. A casino must perform well across all areas to earn a high score.

Licensing & Regulation

We first verify that a casino holds a valid licence from a reputable regulator. For UK-facing brands, a UK Gambling Commission (UKGC) licence is essential and carries the most weight in our scoring. We also accept and evaluate Malta Gaming Authority (MGA) licences for broader European sites, and we note Curaçao-licensed operators only when they can demonstrate additional player protections. We check licence status, complaints history, and whether the operator is transparent about its regulatory body.

Game Selection & Software Providers

We review the full library of slots, live casino, and table games. Strong scores go to casinos with thousands of titles from trusted software providers, including NetEnt, Playtech, Evolution, Microgaming, Pragmatic Play, and others. We test filtering, search, demo play availability, and whether live dealer rooms are professionally run and available on desktop and mobile.

Bonus Terms & Wagering Requirements

Every welcome offer, reload bonus, and free spins promotion is read line by line. We assess wagering requirements (rollover), game contribution percentages, time limits, minimum odds or stake restrictions, and maximum cashout caps. We favour clear, fair terms and penalise misleading or overly complex bonus conditions.

Payment Methods & Withdrawal Speed

We test deposits and withdrawals across crypto, e-wallets, debit cards, and bank transfers. Our score reflects how quickly payouts are processed, whether identity verification is reasonable, and if the casino supports widely used UK and European methods such as Visa, Mastercard, PayPal, Skrill, Neteller, Trustly, and major cryptocurrencies. Hidden fees and slow pending periods reduce the rating.

Customer Support

We contact support through live chat, email, and any available phone line. We expect 24/7 live chat for top-rated casinos, short response times, knowledgeable agents, and helpful resolutions. We also check FAQ quality and whether support is available in English for UK
