The game has a familiar feel with the 5x3 grid and 10 paylines where you will try to match symbols to trigger a win.
The difference this time is that it has the glitz and glamour you would expect for Las Vegas. There are some great prizes up for grabs, so much so that you could win up to 5,000x your stake when you collect enough money symbols. This is available to play at Betano casino. among many other casinos in the UK, and you can get Big Bass Splash free spins when you sign up with the casino.
Joker's Jewels Hot (Betfred Casino)
Harking back to games of yester-year, Joker's Jewels Hot from Pragmatic Play is fast becoming a favourite at many of the best online slots sites. Despite having graphics from the late 1990s, this is a game with great replay-ability. With an RTP of 96.5 percent and a maximum win an eye-watering £6 million, the lack of pizzazz is only like to be so disappointing. It may not have the glitz and glamour of some new slots, but it makes up for it in a stylish old-school design and plenty of chances for a win.
High Flyer (LeoVegas Casino)
High Flyer is another of software giant Pragmatic Play's growing crash game portfolio with a maximum win of £250,000. With high volatility and a huge 97 percent RTP, this is a game that is sure to excite anyone.

It's getting towards spooky season, which can mean only one thing - Expect plenty of horror and Halloween related releases from the best slots providers around. This includes, Nolimit City, which has brought out Blood & Shadow 2 this month. The design features are pretty similar to the original, with the change being the setting of the game in a satanical church. There are nearly three times more ways to win than the original, with a maximum win into the millions. Start playing this ghouly delight if you dare.
Duck Hunters
While the title of this new Nolimit City slot, Duck Hunters, may not exactly set the pulses racing, unless you're an amateur hunter on the side. However, don't let that fool you as you are taking to the deep south of the US to try to catch some ducks on the way to a big jackpot. The price per spin ranges from 20p for those looking for a fun time to £100 for those higher rollers aiming for the biggest wins.

Barz
With a 100% welcome bonus up to £300, plus 50 free spins, new players at Barz casino have a whole lot to look forward to. The slot site came onto the market in 2021, so the site has had a bit of time to get established, and it’s no surprise that the range of games already consists of over 4,000 titles.
At the time of writing, some of the best new games include Moon Princess 100, Big Bass Secrets of the Golden Lake, and Red Zone Blitz, and there are also popular games, retro slots, and a live casino UK customers can enjoy.

Types of New Slots Online
There are lots of different types of new slot games, and as we mentioned earlier, these games tend to be even more innovative and feature-laden than older games. These are a few of the best types of new slots online, which you can try now at almost any pay by phone bill casino or new online casinos.
Progressive Jackpot Slots
Progressive jackpot slot games are seriously exciting because the potential prize money increases every time someone spins. These games can hold top payouts into the millions of pounds, but even if you don’t get that lucky, there are plenty of new games with smaller payouts.
If you take MyriadPlay as an example, there are dozens of big Jackpot King games, which hold a linked prize pot, making it one of the highest payout online casinos. Just like all other new slot games, progressive jackpots can come with hundreds of different themes, and they can also have additional special features like wilds, multipliers, and free spins rounds.
Megaways Slots
While most slot games pay out based on symbols landing on particular paylines, Megaways games do things differently. The number of symbols landing on the reels will change every time you spin, so there can potentially be hundreds of thousands of ways to win.
Megaways slots have been popular for several years now, and more and more providers are starting to use the mechanism, so it’s safe to say there are new Megaways slots being released all the time. Head straight to Barz Casino if you want to play the best new Megaways slots.
TV/Movie Themed Slot Games
If you’re a fan of a particular movie or film franchise, it’s a good idea to look for TV casino games or slot games themed around it. One great example of this is the series of games themed around the animated favourite, Rick and Morty. Film and TV slots usually feature the main characters and sometimes even the theme tunes, so they offer a totally unique way to get more involved.
Slots with Bonus Games
Bonus games are a great addition to new slot games because they give you extra chances to win. Some bonus games might simply come in the form of a free spins round, which can be triggered when you land a certain number of scatter symbols, while other bonus games might be more interactive - for example you might need to spin a virtual wheel or choose boxes to reveal a prize.
Rise of Olympus Origins, with its totally unique method of triggering the bonus round, is definitely one to look out for.
Video Slots
Most new UK slots are video slots. This just means that they’re really modern, as opposed to looking like retro slot machines. Video slots are almost always themed, so you can play games based on animals, adventure, fantasy, horror, or pretty much any other theme you can imagine. New video slot games also tend to come packed with special features like multipliers, wilds, and free spins.
Slingo Games
If you love bingo, you’ll love slingo too! This game is a combination of bingo and slots, and it adds extra layers of excitement, because it can have lots of different themes, just like slot games. You won’t find slingo at every UK online casino, but in general most sites have at least a few of these games, and as they’re gaining popularity, we expect to see lots more slots sites UK customers can play released in the future.
Best UK Casino Bonus Offers for New Slots
If you’re ready to play some new slot games, claiming a sign-up offer is a great way to do it because these promos allow you to maximise your money so that you don’t have to spend a huge amount. All of the best online casino sites have some form of sign-up bonus for new players, and when you create your account via a link on this page at Bookies.com, you’re guaranteed to get the one you deserve.
One thing to remember is that all UK online casinos will have a multitude of different payment methods that you can use to fund your account, but not all of them can be used if you want to claim bonuses. For example, some sites don’t allow you to use Skrill or Neteller if you want to get a deposit match or free spins, but always check the fast withdrawal casino payment methods to see which ones you can claim a bonus with.
New Slots UK Free Spins
Claiming a 100 free spins or 50 free spins offer is a great way to try out new slot games that you haven’t played before. These offers are usually only valid on certain slots, and they’re often either new releases, or some of the site’s most popular games.
Free spins offers can be given to new players either just for signing up, or for making a qualifying deposit, but regular players might also be able to take part in special offers to get free spins. Depending on the casino site, you might be able to claim hundreds of free spins per promo.
Promo Code: BOOKIES
New Slots 2025 No Deposit Bonuses
No deposit bonuses might be the most exciting type of online casino promo for new slot games. To claim these offers, all you need to do is sign up for your account and log in for the first time - and then some free spins or casino credits will be added straight to your account immediately.
It’s always worth checking the terms and conditions on these offers, as they might be a little stricter than deposit bonuses.
New UK Slots Bonus Codes
Some bonuses for new slots are very straightforward to claim - you’ll get the offer as soon as you log in or deposit. But others require you to use a special code, either when you’re signing up, or at the cashier when you make your first deposit.
If an online casino offer needs a casino promo code, you’ll either find it on this page at Bookies.com, or on the promo page at the online casino site. Make sure you enter it at the right time, as if you forget you won’t be able to go back and add it later.
New Online Slot Games Deposit Bonuses
If you want to explore a wide range of new slot games, claiming a deposit bonus will be best. While free spins offers tend to limit the games you can play, a deposit match is more flexible, so you should be able to use it on all (or at least most) of the new games we’ve mentioned on this page.
Claiming a deposit bonus is simple - you just need to sign up and make a qualifying deposit, and then you’ll get a percentage of it as extra bonus cash to use on games of your choice.
New Slots Payment Methods
Casino sites offer a whole lot of different casino payment methods that you can use when you’re playing new UK slots online. Each method has its own pros and cons, including different withdrawal timelines, so it’s important that you choose the right one for you, whether it ends up being Neosurf casino payments or an alternative.
Apple Pay
Apple Pay is highly convenient and secure, as it’s linked to your bank card. If you’re using an iOS mobile device, you can use Apple Pay to send money directly to and from your bank account, without needing to enter your card details every single time. Apple Pay withdrawals usually work on the same timelines as bank cards, so you might need to wait between one and three days to get your money when using casinos with Apple Pay.
Google Pay
Google Pay is basically the Android equivalent to Apple Pay, so while it’s great for Android mobile users, you’ll need to switch to another method if you’re on your desktop. Google Pay casinos are safe and secure, and as the money goes directly in and out of your bank account, you don’t need to worry about setting up or funding any additional accounts at a safe online casino.
Similar to Apple Pay, Google Pay deposits are instant, while withdrawals might take a few days to reach you.
Mastercard
Mastercard is one of the most popular payment methods at new UK online slots sites - just remember, you can only use a debit card, not a credit card. To make a Mastercard casino deposit, you’ll just need your card details, the same as you would for any other online purchase.
Withdrawals tend to take a little longer than with e-wallets, as the timeline largely depends on your own bank. In general, you should expect to wait about 1 - 3 days to get your money.
Visa
Visa deposits and withdrawals at online casinos work in a very similar way to any other bank cards, for example Mastercard. Casinos with Visa are totally secure, so you never have to be concerned about your money falling into the wrong hands. One difference here is that some UK gambling sites support extra fast withdrawals via Visa cards, so you might get your cash within as little as two hours.
Trustly
Trustly is a really unique payment method, which allows you to move money directly in and out of your bank account, without having to provide the online casino with your personal banking details. It’s a great alternative to a traditional bank transfer, and it’s extremely secure and mobile-friendly, and the transactions are much quicker than bank transfers, so Trustly casino options are becoming more popular.
Paysafe
Paysafecard is a prepaid voucher that can be used to deposit into an online casino account. It’s a good option if you want to retain some level of anonymity, as you don’t need to provide the casino with your banking details or bank card details.
Paysafecard deposits should reflect in your account immediately, but it’s worth keeping in mind that you can’t withdraw using this method, so you’ll need to use an alternative, like a bank transfer even when using online casinos that accept Paysafe.
Neteller
Neteller is a secure and convenient e-wallet, and it’s separate from your bank account, so you won’t need to provide the casino with your card details. Neteller casino withdrawals also tend to reach you much quicker than other methods like bank transfers.
One thing to keep in mind is that some online casinos restrict you from using Neteller and Skrill if you want to claim the welcome offer, so it’s worth checking the terms and conditions before you deposit.
Skrill
Skrill is very similar to Neteller and has most of the same pros and cons. On the plus side, Skrill is a secure method that helps you keep your online banking transactions separate from your personal bank card, plus withdrawals can be instant as soon as the online casino has processed the request. Be aware that you may not be able to claim welcome bonuses with Skrill casino deposits.
