The best new online slot sites in the UK in 2024

A rundown of the best new online slot sites in the UK, from the best choice for free spins to the top mobile site

(The Independent)

Online casinos offer customers the chance to play games at the touch of a button, and alongside roulette or blackjack, one of the most popular options is new online slots.

Slots games allow punters to try their hand at a variety of specific genres and titles, from traditional slots to new slot games.

As always, it is important to select slot sites based on your own personal preferences.

Below, we’ve reviewed the top-rated new slot sites and their offerings, ranking them based on their bonuses, free spins, tournaments, app offering and more, so that you can find the best new slot sites for you.

Best new slot site for bonuses: Neptune Play

Neptune is one the newest of new slots sites, having launched in 2024 as the latest launch from the Aspire Global group, which now has an impressive 42 online casinos in its portfolio.

This new UK slots site focused primarily on the slots category, with limited options when it comes to live casino and table games. Nevertheless, you’ll find slots from most of the big-name developers on Neptune, including NetEnt and Play’n Go.

Neptune Play is the best option for slot enthusiasts seeking valuable bonuses. Its welcome offers customers a 100 per cent bonus up to £200 and 25 no wagering free spins on their Book of Dead game, after signing up and depositing a minimum of £10.

There is an extensive range of payment options on offer too, and the Drops & Wins feature is also worth a mention – this gives players a chance to win a share of £2 million each month by playing selected Pragmatic Play slots.

Neptune is a new slots site, so naturally there are areas that require refinement. The library of games could be larger, but the makings of a top slot site are there. Its welcome bonus alone makes it worth considering, giving new users a deposit bonus and 25 free spins on Book of Dead, which carry no wagering requirements.

Note that your deposit bonus will need to be wagered 40 times over before it can become withdrawable and needs to be played through within a day of being credited to your account.

The same goes for the free spins, which are only valid for 24 hours and are valued at 10p each.

With a range of impressive bonuses, starting with its welcome offer, Neptune Play is certainly one of the best new slot sites to consider on the market.

Best new slots site for free spins: MrQ

MrQ is pretty fresh compared to a lot of slot sites. Interestingly, Mr Q carries an impresssive reputation in the online gambling community.

Their popularity might be related to the 6.8 million free spins they handed out last year via various promotions, including their solid welcome offer.

When you register using the MrQ promo code INDY2024, you can get 75 free spins worth 10p each on Book of Dead with no wagering required and no cap on any winnings.

You’ll need to deposit and spend £20 after signing up to unlock the free spins, but keep in mind any wagers on live casino or table games won’t count towards the spend requirements.

In our view, MrQ is the best new slot site for getting free spins due to this welcome offer of 75 no wagering free spins on Book of Dead after a £20 deposit. Expect futher offers with regular use of its online casino, including free spins and table game bonuses.

In addition, a high level of mobile optimisation and speedy payouts make Mr Q a favourite among UK players, and you can play safe in the knowledge that it is a well-regarded slot site.

Top new slot website for slot tournaments: Bally Casino

Bally are a well-established US gambling brand dipping their toe in the water of the UK market.

Bally’s welcome offer is not quite as valuable as others on the market and their slot library is exactly the same as all the others under the Gamesys brand, such as Jackpotjoy, Virgin Games or Monopoly Casino.

But, where Bally Casino stands out in the crowd as a new slots site is for its slot tournaments. Players who relish tournaments will revel in their gaming options. They offer a free-to-play Slot Masterstournament, where players can earn cash prizes of up to £50.

Once registered, existing customers who enjoy slots will benefit from the chance of being able to enter the free-to-play slots tournament Slot Masters daily. Cash prizes are available for top performing entrants.

Bally Casino also offers a particularly user-friendly site experience on both desktop and mobile, despite their underwhelming welcome offer compared to competitors.

Best new slot site for Megaways slots: King Casino

The crown jewel in King Casino’s library of slot games is their large selection of Megaways titles.

King Casino is the best new slot site for Megaways slots. They have an impressive selection of over 100 Megaways titles, including popular games like Eye of Horus, Fishin’ Frenzy, King Kong Cash and Big Buffalo, giving Megaways fans plenty to go at.

In addition, their welcome package offers up to £150 and 50 free spins, and although the free spins aren’t for any Megaways titles, they also have the ‘Wager Free Wednesday’ promotion, which gives users who have deposited £10 or more in the last seven days five free spins on Book of Dead each week.

King Casino is a slightly busy casino site with slot titles splattered everywhere throughout, but it’s easy enough to find your way to the Megaways section and the promotions page, and the overall user experience is still straightforward.

Best new mobile slot site: BetMGM

BetMGM is the best new mobile slot site. They have enjoyed a strong start to life in the UK since launching in 2023 and their cause has been aided with their excellent casino app.

BetMGM make life easy for customers who want all their betting needs at their fingertips, making it straightforward to switch between the casino and sportsbook sections.

Their app carries the same strong collection of slot titles as the desktop site and offers a particularly good experience playing on a smaller screen.

As well as their robust all-in-one casino and sportsbook app – which offers a seamless experience for mobile players – they have a 100 free spins welcome offer, which will suit those on a low budget as the minimum deposit is £10.

The sign-up offer features 100 free spins on Big Bass Splash. To claim the free spins you must deposit £10 or more and play £10 or more on eligible casino games (all except live casino and table games are eligible).

The free spins for popular slot game Big Bass Splash are worth 10p each.

BetMGM offers a sleek gambling experience for all customers, making it one to watch among the new UK slots sites online.

Best new slot site for progressive jackpot slots: Buzz Casino

Buzz Casino is the best new slot site for progressive jackpot slots. Its sign-up offer certainly suits slot players, offering 200 free spins when you deposit and bet £10 on any slot title.

Bingo fans will know all about Buzz, who are now trying to be top of the shop when it comes to new slot sites with their online casino. Their casino split away from the bingo side of the business in 2023, and currently has something to offer the majority of online casino goers. This particularly applies to slot enthusiasts, with over 1,200 games to choose from.

There’s a strong line up of progressive jackpot games from the likes of Power Play and Red Tiger, while Buzz’s promotions cater more to slot users. In addition, they have a wide range of jackpot games from top providers, such a Jackpot King.

Buzz offers a user-friendly site experience on both desktop and mobile, which paired with their welcome offer that requires a £10 deposit to unlock 200 free spins, makes a compelling case to sign up online.

There are a few factors to keep in mind with this casino bonus. Initial deposits must be made by either debit card or Apple Pay to qualify and the free spins are only eligible for the Fire Blaze Blue Wizard Megaways title, which has a RTP value of 95.47 per cent.

Free spins are credited in the form of a £20 slot bonus, which will need to be wagered 20x.

Being credited to you as a bonus means you can choose the value of each spin. You could choose to wager 50p per spin, meaning you’ll get a maximum of 40 free spins, or 10p per spin and get the full 200 spins.

There’s a lot to like about Buzz Casino as a slot site, particularly when it comes to the range and value provided by its progressive jackpot slot games.
