Part of the reason is that slots are split into three sections of the site – Casino, Games and Vegas.

Best New Slot Sites UK
The primary criteria for choosing an online slot site should always be safety. That’s why many players prefer to stick to an established brand they are already familiar with. However, just because a casino is new, it doesn’t mean it shouldn’t be trusted. In fact, there are lots of reasons why it’s beneficial to join new slot sites. These include:
- Attractive Welcome Offers – most new slot sites offer a generous sign-up bonus to gain attention
- Modern Payment Methods – new slot casinos are tuned in to newer, faster, more efficient payment methods
- Advanced Technology – a newly launched slot site will use the most advanced and up-to-date tech to make your gaming experience smooth and streamlined
- Newer Games Libraries – new slot sites want to move forwards not backwards, so they search out new providers offering innovative games and features
- Fresh Outlook – older slot machine sites can be a little stagnant and repetitive while new slot sites take a fresh approach to promotions, payouts and rewards to stand out from the crowd
As long as the new slot site is licensed and regulated by the UK Gambling Commission, then you can be assured of its safety. Let’s take a look at three new UK slots sites and what they offer:
| New Casino | Launched | Key Features | Secure Link |
|---|---|---|---|
| Luna Casino | 2025 | Over 6,000 slots Double welcome offer and daily rewards | Go to Luna Casino |
| Casino Kings | 2024 | Over 4,000 slots Lots of promotions including rewards programme | Go to Casino Kings |
| Pub Casino | 2023 | 1,400 slots with daily tournaments Multiple banking options | Go to Pub Casino |
How To Choose the Best Slots Site in the UK?

Why You Can Trust Our Ranking
At iGamingNuts, every one of our writers is a slot player. We have years of experience in playing and reviewing slot games and slot sites, so you can trust our insights and ratings. If we don’t feel that a site is good enough to recommend, it doesn’t make the cut. It’s as simple as that. Plus, we clearly state both the pros and cons of each slot site, so you get the full honest picture of every site that we test.
Types of Online Slots Available at Real Money Slot Sites
Online slots come in a variety of different styles, themes and configurations. You only have to look at an online casino lobby to see the various tabs and filters for different types of slots. Below, we’ll give you a quick summary of some of the slot types you will come across and the main features of each:
Classic Slots
Similar to retro fruit machines, classic slots tend to have just 3 to 5 reels, limited paylines and include traditional symbols such as cherries or 7’s. They are suited to players who prefer simplistic gameplay and old-school visuals.
Examples include Fire Joker and Lucky Diamonds.
Video Slots
Found in all good slot sites, video slots refers to, basically, any modern online slot game. These come in a multitude of themes and formats and have different sized game grids, bonus features and mechanics. They can even look like full-scale movies with sleek animations and characters.
Most current slots players play these with popular examples including Sweet Bonanza and Money Train 4.
Progressive Jackpots Slots
These are slots that have an additional linked prize pot linked to them. Every time you spin, a small percentage goes into building the pot until one player triggers it. This can be on a timer, for example, ‘Must Hit within the Hour’ or they can be ongoing until randomly triggered, often reaching into Million Pound prize pots.
Examples include Mega Moolah and Jackpot King.
Megaways
Megaways slots have a dynamic game mechanic that changes the number of rows and paylines on each spin. They often come with a cascade or tumble feature too, so players can hit multiple line wins on one spin.
Highly popular, they suit players who like innovative and ever-changing gameplay – popular examples include Big Bad Wolf Megaways and Bonanza Megaways.
Slingo
Slingo games are a cross between slots and Bingo where you have to match numbers on a grid to trigger the features. Slingo is more aligned to Bingo players than slot players, in my opinion, but are still popular with options such as Slingo Starburst and Slingo Cleopatra.
Branded Slots
Your favourite movies, TV shows and even music stars brought to life in slot games. Branded slots use familiar characters, sets, catchphrases and soundtracks of popular culture genres to entertain you.
Popular examples include Rick & Morty Megaways and The Goonies.
Cluster Pay Slots
Cluster Pay slots are games without traditional paylines. They usually take place on a larger game grid, for example, 7×7 and winning combinations are formed by matching symbols that are linked horizontally or vertically anywhere on the grid. The amount of symbols you need varies per game but is usually 3 or 5 depending on game size.
Popular examples include Sugar Rush and Rise of Olympus.
Seasonal Slots
When it comes to slot themes, there is no limit to your imagination! From Egyptians to Eggs, Aliens to Animals and Grannies to Gods, there’s something for everyone. Many slot providers create seasonal slots around different times of the year. These are full of great visuals, iconic symbols and speciality bonus features.
Take a look at our seasonal slot picks below:
Best UK Slots to Play
Although slot choice, ultimately, comes down to personal preference, there are some slots that tick all the boxes for the majority of players. These tend to be high RTP slots, with multiple bonus rounds, striking visuals and entertaining gameplay.
Our own iGaming slot experts personally play and review each slot to test them out. Using our years of experience and a distinct rating system we judge each slot equally and honestly and give them a feature score out of 10. With that in mind here’s what we consider to be the best UK slots:
- Money Train 2 – Relax Gaming
- Immortal Romance – Games Global
- Sweet Rush Bonanza – Pragmatic Play
- Wanted Dead or a Wild – Hacksaw Gaming
- Gates of Olympus 1000 – Pragmatic Play
- The Goonies – Blueprint Gaming

- 9 Pots of Gold – Gameburger Studios
- Starburst – NetEnt

Whether you like a slot game or not, tends to come down mostly to its theme and volatility. High volatility slots pay out less frequently but tend to deliver bigger wins, while low and medium volatility slots give smaller payouts but on a more frequent basis. The top slot sites offer games with low, medium and high volatility slots.
