5 Newcomer Online Casinos That Impressed Our Team in 2025

by Angelina Vodenicharova, 25 December 2025

Not every new online casino wows, but a select five did in 2025. Think 247Bet’s diverse live tables or BetMGM’s exclusive games, which prove that focused perks and cleaner journeys can elevate a brand to compete with established UK casinos.

From bold launches to refined sites, the casinos we’ve picked are new and fresh.

Top 5 New Online Casinos That Stood Out in 2025

We tracked the rise of UK online casinos throughout the year and selected the five that truly impressed us. Some, like 247Bet, came in swinging with a game collection of over 3,000 titles, while others finally refined UX, bonuses, and withdrawal processes enough to challenge the top-tier sites we already trust.

247Bet – 3,000+ Games From Day One

A 2025 entrant with an uncommon breadth, 247Bet ships with over 3,000 titles spanning blockbuster slot series, such as Big Bass Bonanza by Pragmatic Play.

At the same time, as we discovered during our 247Bet casino review, it also offers games from niche studios like Fantasma Games and Neko Games.

This diversity means there are games for both new and experienced players, positioning the brand as a serious all-rounder from launch.

Beyond volume, 247Bet impressed our experts with fundamentals all best online casinos have nailed down, such as swift onboarding, clear limits, and stable payouts.

BetMGM – Exclusives & MGM Millions Jackpots

BetMGM stands out for its exclusives, including Push Gaming’s Mysteries of Luxor, and the MGM Millions three-level jackpot network, which layers steady drops with headline wins.

We’re not just talking about exclusive slots – the casino also offers many branded live table games.

As we discovered during our BetMGM casino test, the 2025 product feels fully dialled in: solid app performance, reliable banking, and frequent promotions tied to its exclusive catalogue.

Slots n’Play – Diverse Payment Methods

Most newcomers offer limited banking options, but when we conducted our initial Slots n’Play casino review in 2021, we already noticed that the site launched with eight payment methods.

This provided unusual flexibility from the start, but some kinks still needed to be ironed out. We were mainly waiting for its game collection to grow, and now that it offers over 1,000 slots, it has once again caught our attention.

Combined with a straightforward lobby and sensible limits, Slots n’Play matured into a reliable everyday choice rather than a “bonus-only” stopover.

Rialto Casino – Live Tables From The Vic London

Rialto streams live from iconic UK casinos, such as The Vic London, injecting authenticity while maintaining online conveniences like quick seating and table variety.

This hybrid identity is why Rialto rose on our radar in 2025.

The studio mix is competitive, but it’s the venue-sourced streams that differentiate sessions, especially for players who favour blackjack and roulette. If that’s you, check out our Rialto casino review to learn more about its live table games.

VegasLand – Multi-Part Welcome Over Three Deposits

VegasLand’s welcome package is divided across your first three deposits, making bankroll planning easier and extending early value beyond a single session. It’s a practical, player-friendly twist that lets cautious newcomers sample slots like Starburst and Book of Dead.

This promotion structure helped VegasLand stand out to our experts in 2025.

Our first review of VegasLand casino was published back in 2022, so the casino is not brand new. Yet, it’s on this list because it finally caught our attention with its multi-part bonuses, which are increasingly rare among established UK online casinos.
