Newest Online Casinos UK – Criteria on How We Rate in 2025

When writing casino reviews, we never leave things to chance. Instead, our team of experts stringently tests all UK casino sites using the same practices. We do all the homework to help players make the most informed choice so they can get on with playing their favourite games!

Let’s explore the factors we look out for when ranking each platform.

• Game variety: Everyone has their own preferred casino games, but it’s always nice to have a wide range of choices. Whether you prefer spinning the reels on slots or progressive jackpots or playing table games like roulette, baccarat, or blackjack, we love seeing new casino sites offering a full, diverse selection of games.
• Bonuses: One of the best things about a new casino is the bonuses you’ll be able to claim. Often, they will be much more generous as a way to attract new players. Expect bigger and better welcome offers, and other promotions such as free spins, cashback, and top-notch loyalty programmes.
• Security: Even though a new online casino may offer a great selection of games or big bonuses, we always check whether it’s properly licensed. This factor is easily the most important, as it keeps you safe online. At Slotozilla, we’ll only recommend sites licensed by the UK Gambling Commission, Malta Gaming Authority, Alderney Gaming Control Commission and Curacao eGaming.
• Customer support: Even though a casino site is brand new, it should still offer a high level of customer support if you run into any issues. A comprehensive FAQs page is a good start, but when you need to get in touch, nothing beats live chat with a quick response and a well-trained agent. New online platforms that go the extra mile offer a phone number, email address, and social media channels to get in touch.
• Software providers: New casino sites are aware that top games are the key to attracting new players. That means they need to partner with the biggest brands in the industry. For slots, we are talking about Quickspin, IGT, and Blueprint Gaming. If live games are available, we prefer brands such as Evolution Gaming, Swintt Live, and Pragmatic Play.
• Payment options: Our team always checks the payment options, and whether a casino offers the popular ones such as Mastercard and Visa. If so, it gives the platform an element of trust. However, we understand you may prefer alternative payment methods such as e-wallets, evouchers, Pay By Phone, and cryptocurrency. Thus, the more payment options offered, the better.

Let’s take a look at the main game types to play.

• Table games: New online casino sites know that British players enjoy table games. That’s why they will give you the option of RNG versions such as baccarat, blackjack, video poker, craps, roulette and Andar Bahar.
• Live games: For a real immersive thrill, nothing beats live casino games. New casinos will always offer you this option, supplied by either Evolution or Swintt Live. You can enjoy all the top table games or a game show.

New Mobile Casino Sites

Nowadays, via mobile browsers, it’s possible to play all your favourite games on all types of casinos, from no wagering casinos to new ones. Moreover, many casino sites now offer dedicated apps for iOS, Android and Windows devices.

The mobile gaming experience is the same as when you play on a computer. All the games will be at your fingertips, and on some apps, you’ll even be able to claim exclusive app-only promos like free spins or matched bonuses.

Here at Slotozilla, we realise the importance of great mobile casinos. It’s estimated that over 60% of players enjoy casino games on a mobile device. Therefore, the design of casinos and usability need to be top-notch. Not to mention great bonuses and a quick registration process.
