Why are there fewer new slot sites than there used to be?

Over the last few years, several new slot sites and casinos have been launching in the UK every single month, but the avalanche of new slots sites slowed down a bit last year and we expect this to continue into 2024.

The major cause of the slowdown is the UK government’s plans to overhaul the Gambling Act (the underpinning legislation for the UK gambling industry, online and offline). The review has been repeatedly delayed over the last couple of years and many operators have been reluctant to launch new UK slot sites without knowing exactly what the changes (stake limits, affordability checks, curbs on advertising) are going to be and how it will affect their business.  A fresh round of consultation took place early in 2023 and the responses were published in March.  Now, at last, the White Paper has been published but although it addresses all of these issues the details are yet to be resolved; stake limits, for example, could end up at anywhere from £2 to £15 a spin. Until these very important details are finalised (through consultations that are going on at the moment), it’s likely that operators will continue to be cautious about launching new slot sites in the UK.

Are new slot sites always brand new?

A new slot site doesn’t necessarily mean a new operator!  It can be any of the following:

  • New site on a new platform – it’s rare to see independent slot sites which are genuinely and completely new to the UK but they do appear from time to time e.g Jackpot.com and Happy Tiger.  As these operators have recently passed the rigorous vetting procedures for a UK Gambling Commission licence, players can feel confident about giving them a try.
  • New site on an existing platform (house owned) – an already successful operator launches a new site on their own casino platform e.g. Pub Casino from L&L Europe.
  • New site on an existing platform (skin) – the site’s owner may or may not be new to the industry, but the casino software, management and licensing is supplied by a white label provider such as Jumpman, Grace Media or Progress Play.  There’s certainly plenty of these! Some of them, however, restrict the number of accounts that one player can open and/or the number of welcome offers that one player can claim.
  • Sportsbook that added a casino – this type of site proved very popular with our users last year and we expect the trend to continue for 2023 e.g. Kwiff.
  • Relaunches – it’s not unusual for slot sites to open in the UK and not gain much of a player base, either because the operator doesn’t make much of an effort to promote their new site or because the welcome offer isn’t appealing.  When a site that few players have even heard of gets a makeover and a new welcome offer, we’ll add it to the listings here.
  • Platform changes – sometimes casinos will close on one white label platform and reopen on another, e.g 666 Casino moving from White Hat to Aspire.  The player base usually does not transfer so these may as well be brand new sites, with everyone eligible to claim the welcome offer even if they’ve played there before.

Why play at a new slot site?

Many players move on to new sites because they want to claim a fresh welcome bonus offer but there are many other reasons why you might want to try out somewhere new.

  • Ongoing/regular bonus offers – it’s not all about the welcome offers. Regular/ongoing deposit offers of slot bonus or spins give players the opportunity to try out different slots.
  • Free Spins – many players clearly prefer free spins to a slot bonus and plenty of new slot sites are all about the free spins, sometimes with no deposit required.
  • Wagering requirements, caps on winnings etc – Players may seek to move on if they consider wagering requirements to be too onerous or if there are too many restrictions on what can be won from bonus play, especially as there are now quite a few new slot sites with no wagering requirements
  • Exclusive & network promotions – Promotions such as tournaments, raffles and sharepots make play more interesting and a new site that offers these may be very attractive to players (especially if they are not available anywhere else).
  • Look and feel of the site – just as at a bricks and mortar casino, the decor can make a big difference to how enjoyable the player experience is!
  • Payment methods – players who want to be able to deposit from a mobile device may find it more convenient to switch to a slot site with Paypal or MuchBetter, or where they can pay by phone bill.  Or perhaps they are attracted by the safety, security and convenience of Trustly or want to manage their spending by using a prepaid voucher system such as Neosurf or Paysafecard.
  • Better VIP / player reward scheme – It’s not only the size of the rewards, but the nature of the rewards.  Some players prefer loyalty bonuses, some prefer cashback and some prefer daily free spins – and with such a wide variety of player reward schemes out there, there’s something for everyone.
  • Playability on different devices – A player with a new phone or tablet may be looking for a site that works better on the latest devices.
  • Selection of slots  – Players may move on in search of a particular slot they want to play – whether it’s an evergreen favourite like Fluffy Favourites,  Rainbow Riches or Immortal Romance, or the latest Big Time Gaming or Pragmatic Play thriller.  Perhaps the site they currently play at doesn’t offer any slots from that provider or doesn’t have any of the highest RTP slots.
  • Availability of new slot game releases  – One thing that really irritates players is when the slot site they regularly play at is slow to add new releases.  When an eagerly anticipated new game comes out, you want to be able to play it right away, not months later!  Check out our New Slot Games page for more information about the latest slot games and where to play them.
  • Availability of progressive jackpots – Not all slot/casino sites offer progressive jackpot slots and in 2023, a good selection of jackpots is getting harder to find.  For example, it is quite common for IGT slots to be on offer but without the Megajackpots collection.  Other sought after progressive jackpots include the Jackpot King games by Blueprint, the Red Tiger Daily Jackpot slots, Playtech’s Kingdoms Rise and Age of the Gods, Microgaming’s Mega Moolah and WOWPots, Netent’s Mega Fortune games, Big Time Gaming’s Megapays and Relax Gaming Dream Drops.
  • Slot game Return To Player – These days, many slot games have “RTP ranges”.  This means that the casino can choose where to set the RTP of a slot game from within a range. Casinos are required to make RTP information available, but they don’t have to make it especially prominent so players may not realise unless they take a look in the game documentation that they are getting a lower RTP on their favourite game than they could elsewhere – but when they do realise, they will very probably be looking for a new place to play.  We expect many more game providers to offer RTP ranges in the future and many more casinos to use them.
  • Trust and safety – a poor customer service experience and/or difficulty withdrawing winnings are issues which are pretty well guaranteed to send a player looking for somewhere new to play.  What you may not know is that the Gambling Commission require all operators to rate their own degree of insolvency protection (what happens to player funds if the operator goes bust) and a great many slot sites including some big names are classified as “Not Protected” (meaning that players would be in the same position as any other creditor).  A slot site with Medium or High protection gives greater security.
  • Intrusive ID and affordability checks – all operators are required to carry out enhanced ID and affordability checks once player activity exceeds a certain level, but some are more heavy handed about it than others and players can’t be blamed for wanting to move on if, for example, supplied ID documents are rejected without any indication of why and/or repeated requests for further documents are made.  Now the White Paper has finally been published, consultations are taking place about how affordability checks will be standardised across the industry.

Are all the slot sites on this page brand new?

We leave slot sites on this page until we can see from our interaction data reports that no-one is interested in them any more, so you will find sites up to a year old here (sometimes even older).  We also sometimes add older sites if they have changed platform, never got any publicity when first launched or haven’t previously had a slots welcome offer (as is often the case with sportsbooks and lottery betting sites).

New slot sites – trends and what to expect in 2023

  • Design changes – Some big changes have had to be made in slot game design over the last couple of years.  Autoplay is no longer allowed and games are no longer allowed to show celebratory animations and the like for wins that are less than the spin value.  There’s also a minimum time of 2.5 seconds between spins.  The result of these changes is that some games are getting released late in the UK (e g Starburst XXXtreme) or even not at all (e.g. games with a bonus buy feature that the game provider doesn’t want to remove just for the UK market).  The White Paper mandates further consultation on game design to take place in autumn 2023 so there could very well be more changes to come.
  • Slots with higher variance and lower hit rate – An unintended side effect of the design changes is that because small “wins” that are less than spin value are now barely distinguishable from losing spins (in terms of what you see and hear rather than the effect on your bankroll) they no longer contribute to the entertainment value for players.  Therefore, this type of “win” is less likely to be included in the design of future games and this is making everything higher variance, with more losing spins and fewer, bigger wins. The popularity of Big Bass Bonanza (and its even higher variance friends and relatives) is a perfect illustration of this trend and there’s even some slot games now (such as Money Cart by Relax Gaming) where any spin has just two possible outcomes – the bonus round or nothing.
  • No deposit offers – New players now have to undergo age and ID verification before they can deposit or play at a site and this also applies to no deposit offers and free demo versions of slot games.  You might think this would result in fewer no deposit offers as the degree of player commitment required to claim a no deposit offer is now so much higher, but in fact the reverse has happened. Higher player commitment means that players who take up no deposit offers are now more likely to go on to make a deposit afterwards and this has made no deposit offers more worthwhile for operators.
  • Payment method changes – Since 2020, slot sites have been prohibited from accepting any deposits via credit card and this applies to all forms of gambling, online or offline, apart from the special case where someone buys a lottery ticket along with their grocery shopping.  The long term effect of this on other payment methods is still developing as operators need to ensure that a credit card hasn’t been used at any stage of the process.  PayPal made it easy for operators to do this by implementing a solution themselves (if you make a deposit using PayPal you will find that you cannot use a credit card to fund it), but many operators don’t want the hassle and are now discouraging players from using payment methods apart from debit card by excluding those deposits from the welcome offer.  Trust and safety will no doubt become even more important as players are likely to be more cautious with debit card details than with credit card details (credit cards are far less of a nuisance to cancel).  In June 2022, a number of UK slot sites stopped accepting deposits via Boku and we understand this was for regulatory reasons; it remains to be seen whether the few sites that still accept it follow suit. Other pay by mobile deposit methods have also been affected; at Intouch sites, for example, if you deposited using mobile phone billing you had to demonstrate to them that the phone bill had been paid before you were allowed to withdraw any winnings.  On the other hand, high tech payment methods such as Trustly, Muchbetter and Astropay now have increasing presence at UK online casinos.
  • Mobile slots – As so many players now do all of their play on mobile devices, new slot sites that are designed to work on mobile and/or with the safety and security of a mobile app are in the ascendant, often – like Winomania and the new for 2022 Happy Tiger – with unique mobile slot games you won’t find anywhere else.
  • More high profile exits from UK – Over the last couple of years, international operators have been leaving the UK market, a recent high profile example being Genesis Global at the end of 2022.  In many cases it’s a commercial decision as taxation changes and increased regulation have been making it harder and harder for operators to trade profitably in the UK, but a few (such as BGO) were pushed following regulatory breaches.   The HUGE fine – £19.2 million – that was slapped on the William Hill Group in March 2023 is exactly the sort of thing that might cause more operators to consider leaving.   Not to mention the repeated regulatory actions that were taken against InTouch Games for historical failings which ended in their licence being surrendered.
  • Less choice of platform – With so many operators leaving, a bigger and bigger slice of the new slot sites pie is being taken by Jumpman skins (Jumpman are UK based, holding an Alderney licence as well as UKGC) with their distinctive Mega Reel welcome offer (and nasty wagering requirements).
  • Less generous welcome offers – this certainly won’t be popular but it is an inevitable consequence of the increased regulatory and tax burden, with operators really starting to feel the pinch.  It’s not just the size of the bonus that’s coming down, either – changes in the terms and conditions affecting bonus expiry, caps on what you can win and restrictions on which games you can play with your bonus can all make a bonus less valuable to the player.  The silver lining is that we may see some sites start to focus on player retention rather than player acquisition – which should turn out to be good for the players on the whole as they’ll be given cool promotions on an ongoing basis, not just when they sign up.  Whatever happens, we’ll continue to bring you the best new slot sites in the coming year.

New slot sites are safe to play at as long as you stick to sites that are licensed by the UK Gambling Commission. The slot games themselves are checked for fairness and the operators have to meet responsible gambling safety standards.  We only review UK licensed sites and for added security, we also report on each site’s level of players funds protection.

There are several different types of new slot site welcome offers. Slot bonuses can be used on the slot games of your choice. Slot spins are for one specific slot game. Some welcome offers award a variable amount of bonus or spins as a result of playing a bonus game such as the Mega Reel, and a few have some form of cashback instead of bonus or spins.  At No Wagering slot sites, any winnings from the welcome offer will be paid as withdrawable cash, but the vast majority of new slot sites have a more conventional welcome offer and you will need to complete wagering requirements before withdrawing your winnings.

The best new slot sites in the UK? There are certainly plenty of new slot sites for UK players to choose from and more are being launched all the time.  Which ones are best for you depends on what you’re looking for – which type of welcome offer do you prefer and which games do you want to play? We include lots of variety in our list of 25 of the best new slot sites so you’re bound to find one that suits you.

In most but not all cases slot games are the same wherever you play them. Starburst and Book of Dead are two very popular slot games whose RTP does change from site to site, so if one of these (or another variable RTP game) is your favourite you can actually get a better payout by changing to a different slot site.
What also varies from slot site to slot site is the size of some of the progressive jackpots. Unlike Mega Moolah which is global, Red Tiger Daily Jackpots and Jackpot King by Blueprint are specific to each site or group of sites, and they get much bigger at some – Paddy Power Games for example – than at others (of course, at very busy slot sites with large numbers of players your already minuscule chance of actually winning one of these jackpots gets even smaller).
