The Best New Slot Sites
New slot sites are launching almost every day, and with so much choice, it can be difficult to decide where to play. That’s where Casivo comes in! We’re always looking for the newest slot sites on the market and their offers for new players.
The best perk to joining any new UK slot site is the generous bonuses on offer. To attract new players, you can expect to see plenty of goodies and giveaways. This will include no deposit bonuses and free spins. The best part about it? A lot of these bonuses won’t require you to spend a penny. We understand that most players will already have their trusted online casinos, but branching out is good. Trying a new slot site will give you more bang for your buck in the form of bonuses.
Jam-packed with games, these new slot sites partner with the same game providers as many of the biggest online casinos. You will find they all include NetEnt, Microgaming, Playtech and more. This means you will be able to claim a great welcome offer and still play on your favourite casino slots. What more could you want?
One of the best features of new slot sites is the addition of jackpot slot games. Popular choices include Mega Moolah and the Jackpot King range such as Ted, Worms and Top Cat. Jackpot slots give you the chance to win real life-changing money. Prizes often exceed £1 million.
Understanding the terms and conditions
Our number one tip to getting the most out of slot bonuses and promotions is to read the terms and conditions. When you understand the wagering requirements and limitations, you’ll be able to use the bonus most effectively. None of the new online slot sites needs any downloads or waiting time. So you can play quickly and easily on any device.
Regulated slot sites
Only join genuine and reputable online slot sites that have a license with the UKGC. Casivo has carefully reviewed every single new slot site on this page to strict criteria. You can be confident that we only publish the very best.
Online Slot Sites in the UK
The choice of online slots in the UK is huge, with new operators launching every month. So what does this mean for you as a player?
When you sign up, you will find a variety of welcome bonuses that will differ between casinos. There’s a huge increase in the number of UK slot sites offering no deposit bonuses, allowing you to bet completely free when you join. An example of this would be a £10 free no deposit welcome bonus.
If free spins are more your thing, there are many of the newest UK slot sites rewarding new players with these. The most popular is no deposit free spins, meaning you can get a taste for particular casino slots before spending a penny of your own money.
Remember, the newest slot sites awarding free spins and bonuses will have terms and conditions. Minimum deposits or wagering requirements will usually apply before you can withdraw real cash. The good news is that most gambling sites will also offer you a deposit match bonus after your free spins, so you get even more value.
One of the biggest telltale signs of a good slot site is its variety and selection of games. Not only should they have a huge amount to choose from, but there should always be plenty of choice in the kind of slot you wish to play.
The big names in gaming software should feature too. As always, keep an eye on the terms and conditions of each bonus, so you know exactly what to expect. Most importantly, enjoy playing on some of the best and newest online slot sites in the UK.
New Slot Sites and New Bonuses
As competition heats up and technology continues to develop, the online slot world in the UK will only get better for players. There’s no limit to how many sites you can join, so it’s worth taking advantage of the best welcome offers on the market.
Free slot bonuses with no deposit are the most exciting prospect – what’s better than being able to play slots for free and have the chance of winning real money? There are also enticing deposit match bonuses, sometimes up to as much as 200%. So, whether you’re a seasoned player or want a dabble with a freebie, there’s something for everybody.
The generosity doesn’t end with a great welcome offer – you can also expect regular competitions, marketing campaigns and loyalty bonuses if you’re a regular player from the newest slot sites. Even if you find your favourite casino and want to stick around, don’t forget to make the most welcome bonuses elsewhere. There’s no limit to how many you join!
Joining several casinos benefits you in several ways. As well as providing great welcome offers, the online casinos want to incentivise players to come back after their first visit, and you may just be offered second and third deposit bonuses or even more free spins.
Casivo has 100’s of options for you, and each new site has been reviewed in detail before being published on our website. We look at important elements such as licensing, deposit methods, withdrawal times, and game selection for players. No slot site will be featured on this page that hasn’t passed our checks, and the score they’ve been given reflects the quality you can expect.
Always read the T&C’s
When you have selected your favourite online slot offer and new slot site and want to sign up, remember to read the terms and conditions for any requirements before withdrawal. This may come in the form of a minimum number of spins, wagering requirements or a deposit requirement. Familiarising yourself with these will ensure there are no nasty surprises when it comes to withdrawing your cash.
Slots For Every Type of Player
There are so many different types of slot games that may be intimidating, especially for a beginner. There are so many to choose from, so where do you even start? Which games you prefer to play depend on many different factors such as RTP, volatility, bonus rounds and much more. Typically slots can be categorised into 4 key areas:
High Roller Slots
If you prefer a larger spin stake, you’re best focusing on slots with a high return to player percentage (RTP). These may sometimes be a little less ‘fun’ than other slots, often sacrificing in-game interactivity and bonus rounds for more focus on the actual reels and spins themselves. A high volatility game is the best kind of slot for a big spender, as landing a win can be harder work, but it’s also much more likely to be worth it.
These days, most, if not all, slots and slot sites can be enjoyed pretty seamlessly on mobile. That said, there’s a difference between being optimised for mobile and actually being designed for mobile. One means it works, and the other means that it’s been created with the mobile user in mind. If you prefer to use slot sites on your handheld devices, then mobile slots will result in a far better gaming experience for you in the long run.
Our definition of a beginner slot would be one with a pretty high RTP, uncomplicated reels and pay lines, and an option of low stakes. This will help you to familiarise yourself with the game without burning through your cash. Once you have a better understanding of how slots work, you can try something a little more advanced, but it’s a great place to begin.
We’re talking about the kings of the slot world, the games that can genuinely change your life in a single spin. Often awarding prizes of well over £1 million, jackpot slots are some of the most exciting you’ll ever play. Progressive jackpots like Mega Moolah are usually huge sums of money, whereas exclusive jackpots can be fewer. Either way, there’s some serious money up for grabs with these.
Best and Most Popular Casino Slots
Bonzana by Big Time Gaming is popular among high rollers and VIP because of the high volatility and big winnings. If you want the possibility to both bet big and to cash out even bigger, this is the most recommended slot machine!
Using your smartphone or tablet to play, we recommend the Starburst slot, which is one of the most popular slots also when it comes to handing out free spins. The slot is developed with a complete mobile-first approach and was released for mobile phones before a desktop version.
Why Rainbow Riches?
Rainbow Riches is one of the world's most popular slots at both online and land-based casinos. The slot where you should look for Leprechauns is a slot where winnings are very common but a bit lower than other slots making it very suitable for beginners.
Why Book of Dead?
By far, the slot machine that has made most slot players to millionaires. The Microgaming jackpot slot is in the Gunnies world record book for handing out £13,213,838 to a lucky player from Leeds playing at BetWay. Maybe you will be the next winner?
Features of Online Slot Games
Slots come in all shapes and sizes, and each has its very own unique way of playing. We’ve already discussed the technology and algorithms behind RTP and volatility, but what about the fun stuff? What kind of features can you expect on an online slot game, and how do you actually win? Let us explain some of the most common bonus rounds and in-game perks of playing on slots.
Landing a ‘wild’ symbol on your reels can see your win increase markedly, and the more of them, the bigger the win is going to be. These super symbols are quite a frequent appearance, but it’s getting them in the right place that really matters. When placed next to a sequence of matching symbols, the wild will replace itself with that same symbol to guarantee a bigger win.
Some of the most popular online slots have a re-spin feature (Starburst, Worms, Wild Antics, to name a few). This may be a bonus round re-spin, where only 2 of 3 required symbols land, and you get another go at bagging the 3rd. Otherwise, it may be a wild re-spin; either way, these lucky features give you an extra chance to land a win, and they can appear at any time.
The highlight of every single slot is the bonus feature, which can be randomly triggered at any time. How you trigger a bonus will depend on the slot itself, but it’s most commonly the appearance of 3 bonus symbols in any spin, taking you away from the reels and into a separate bonus game. This can be in free spins, a win multiplier, and many, many other variations.
Not quite an entire bonus round of their own, but very exciting nonetheless, these in-game features add an extra layer of interactivity to a slot. What happens will depend on the slot, but just a few examples include free wilds, re-arranging reels, extra pay-lines and much more. With this, you’re not always waiting for a bonus round as there’s plenty to enjoy in-game.
Trends on New Slot Sites UK
With so many new slot sites launching, we’re starting to notice many trends across the market’s newest players. One of the most common is the increasing generosity of the welcome bonuses on offer. Competition is higher than ever for new players, so each new slot site is competing by offering the best offers, which of course works in your favour!
Another popular trend is the increase in gamification. Gamification is the term used to describe interactivity on a site, such as levelling up, slots races and rewards. You will find most new slot sites have this feature to make the experience better. Gamification comes in many shapes and sizes, and this completely depends on which operator you sign up to. New slot sites launching in 2021 and beyond are featuring more elements of interactivity than ever before.
- Generous Welcome Bonuses
- Regular Promotions
- Great Loyalty Programmes
- Huge Selection of Games
- Impressive VIP Schemes
- Pay by Mobile
- Accept PayPal
Pay by Mobile on Slot Sites
The concept of a pay by mobile casino is quite a new one, and the best slot sites have now also started accepting this payment method. You can pay for your deposit with your Pay As You Go balance or apply the payment to your phone bill at the end of the month. It’s effortless to do, but the main drawback is that you’re limited to spending £30 through this method.
Slot Sites Taking PayPal
PayPal is becoming the most popular way to deposit at a slot site, and so you will find most new brands will accept it as their primary payment method. Players love it because it’s fast, convenient and safe to deposit with PayPal, but withdrawals are often quicker too. It’s also a good idea to keep your gambling transactions separate from your traditional banking methods.
New Mobile Slot Sites
One of the biggest perks of online slots is that you can play whenever and wherever you want. Any good slot site will have the cross-device capability, including a seamless mobile experience – however, some do this better than others.
Imagine having all of your games available at your fingertips within a few seconds; well, mobile slots make this a reality. Whether you want a spin on a huge jackpot game for the chance of life-changing wins or just a spin on your favourite casino game, mobile slot sites are the best place to do it.
Mobile compatibility is high on the list of our assessment criteria when looking at any casino, as nobody wants to be tied down. If you’re going to be completing your own analysis, make sure to check how the games play across devices.
We always test the mobile version
Each site reviewed by Casivo has been tried and tested on mobile, and by the time we publish them, we can guarantee a seamless slot site experience. This is, of course, alongside other criteria, including licensing, payment methods and selection of games on the site.
Newest UK Slot Sites 2021
The appetite for online slots in the UK shows no signs of decreasing. Instead, the number of new slot sites in 2021 is expected to beat all previous records. Some new casino sites will offer slots and sports betting to compete with the more established gambling sites.
Another trend for the slot sites in 2021 is the competition to provide the fastest payouts. The fast payout at casinos has been seen as the most important factor for customer satisfaction in research. Thus, gambling operators are now adding fast payment methods such as e-wallets to speed up their processes.
It’s worth noting that the newest UK slot sites will often attract brand new players who aren’t seasoned gamblers and perhaps don’t understand all of the rules and regulations. It’s important to understand your offers’ terms and conditions to know what you’re signing up for. Remember to always check for licensing to ensure that the UK Gambling Commission regulates the site and is safe and secure.
What is Volatility in Slots?
There are a few important elements to consider before playing a slot. After the return to player percentage, volatility is probably the most vital piece of information you can have. The volatility of a slot dictates how it plays and will impact your gaming experience, so it’s important to understand.
A low volatility slot will result in more frequent wins but lower value. So you may win 50% or less of your stake many times but often struggle to land that elusive ‘big win’. These are great for beginners, those who enjoy the playing, and a good tactic for completing wagering.
You may have guessed it, but a high volatility slot means fewer frequent wins, but when you do, it’s likely to be several times your stake. These are good for large depositors who have a bit extra to burn through, and they’re often the most exciting kind of slots.
- Frequent Wins
- Lower in Value
- Good for Wagering
- Less Frequent Wins
- Higher in Value
- Good for Big Spenders
Jackpot slots are about the most exciting as you’ll get, with every single spin giving you the chance to win an incredible sum of money. There are thousands of slots that offer a jackpot of some sort, but there’s something bigger and better with the progressive ones. The prize pool accumulates so fast as it runs across all casino sites that have the game, and just one fortunate player can land the cash. Some of the most well-known progressive jackpots are:
Blueprint Gaming is behind one of the most popular progressive prizes, Jackpot King. Triggered randomly on any spin, 5 crowns across the reels will drop you into the feature. You can land yourself anywhere from 30x your stake, right up to the top prize, which is often over £1 million. Some of the slots to have this jackpot includes; Paws of Fury, Ted, Worms, Top Cat and several others.
Exclusively owned by NetEnt, the Mega Fortune jackpot actually holds the Guinness World Record for the biggest payout on an online slot, dropping at a staggering €17.86 million. Another record was broken in 2015 for mobile gaming when the jackpot paid out again at €8.6 million. These huge wins have earned it the name of one of the best jackpots out there.
Mega Moolah is arguably the most recognisable jackpot slot name out there at the moment, well known for its colossal payouts. It has dropped for players across the globe, from the UK to Canada and New Zealand. The minimum it’s ever paid is £2 million, and the most are £16 million, challenging Mega Fortune for the prize of the most generous jackpot.
One of the more classic-style jackpots is the MegaJackpots brand. Featuring old-time favourites like Cleopatra, Siberian Storm and Ocean Belles, this one isn’t as singing and dancing like the others in terms of interactivity, but the wins are just as impressive, often reaching between £500,000 and £1 million. If classic slots with simple pay lines are your thing, you’ll love MegaJackpots.
