Looking for the latest online casinos making waves in the UK? At CasinoGambler.co.uk, we’ve been busy testing brand-new casino sites firsthand, exploring their games, bonuses, and overall player experience.
One notable trend we’ve seen in 2025 is the rise of casinos combining both online gaming and authentic live casino experiences. A great example is a new UK’s ZetBet Casino, offering new, immersive live dealer games from Evolution and Pragmatic Play, including popular titles like Lightning Roulette and Crazy Time. While ZetBet scores highly on gameplay and visuals, we noticed withdrawal speeds could improve, especially during peak weekend hours.
Another newcomer worth checking out is BuzzCasino, particularly appealing for bingo and slots fans. Our reviewers loved their unique welcome bonus—200 free spins on Fire Blaze Blue Wizard Megaways—but found that the site’s mobile optimisation still needs some polishing. Overall, the extensive bingo rooms and player-friendly promotions help BuzzCasino stand out as a promising new entry in the competitive UK market.

What’s New in the World of Online Casinos?
Increasingly, many casinos are seeking to be “one-stop-shops” for all punters, providing them with a fully-fledged sportsbook, complete with wagering enhancements and thousands of in-play markets. This was a rarity just a few years ago. With the growth of B2B sharing and much more manageable technology, many new online casinos can accommodate a sportsbook without having to re-write the business plan.
To some extent, this is also due to a growing homogeneity in the pricing of markets, with fewer mainstream bookmakers prepared to “take a position” in an attempt to attract a larger piece of the market.
This may be a retrograde development overall, but for new online casinos, it means they can plug into new pricing systems and give their players all the thrills of a sportsbook with less inherent risk to themselves. Expect this trend to continue in 2024. More and more newcomers will offer e-sport, US sports and in-play football markets alongside their slots and Live Casino tables.
New Apps and Mobile Gambling
Undoubtedly, most new casinos put at least as much attention into their mobile offering as their desktop site, and often plenty more.
As the percentage of players enjoying their gaming on the go increases, year on year, the quality of device-based play has improved significantly. Software companies that supply the games to casinos now regularly boast about designing their latest adventures with a small screen in mind.
The growth in 5G coverage has hugely increased the confidence of designers, operators and punters alike, knowing interruptions in play are highly unlikely.
New Social Casinos
In the brave new world of sharing and “likes”, new casinos are not slowly jumping on the social media bandwagon. They allow casinos to announce a big win, hype influencers trying out new games and encourage interactions between players and customer service in a less formal environment.
New casinos are increasingly seeing the likes of Tik-Tok and Instagram as growth accelerators.
Of course, this won’t be for everyone, especially older male punters. But given the huge growth of online bingo and poker, in mainly powered by a growing army of female players, social media engagement will increasingly be a feature of new online casinos in the years ahead.
