New online slots games 2021

Some of them are quite basic while others make use of a ton of features and incredible new ways to play. The software developers behind the scenes come up with new ideas all the time to keep slot fans happy. And this is great news if you fall into this category.

We are going to take a closer look at some of the very best new games arriving on your screens. Some of them you may have heard of as their popularity precedes them while others are slightly less known but are just as awesome.

Let's get straight into it and check out some of those top titles.

Diamonds of The Realms (Play'n GO)

One of the most popular new slots online is the Diamonds of The Realm game by Play’n GO. The growing fascination with ancient realms and kings and queens of old continues into the casino arena. And this game brings it all together nicely with some fantastic prizes and features on offer.

It's possible to hit an incredible 20,000x win during the course of this game and depending on the size of your bet, this could be a life-changing sum of money. There are random multipliers to be found as well as a top free spins round that can really deliver the goods. And free spins can be retriggered by collecting more diamonds during the bonus round. Helping King Arthur has never seemed like such a profitable proposition.

Porks Knox (NetEnt)

Fort Knox is famously home to America’s huge gold reserve and NetEnt have turned this concept into one of the greatest new online slots UK. The idea of piggy banks is nothing new for slot lovers, but this game takes it to a whole new level with 3 amazing jackpots up for grabs.

The game features 20 fixed paylines that sprawl across 5 reels and 3 rows of action. The volatility is around the medium mark and the RTP comes in around 96%. Apart from the 3 big prizes on offer, there is also a cash stacker bonus that can see an incredible boost to your balance. Don’t forget to keep an eye out for the mystery symbols that can suddenly change into any of the others except the scatter symbols.

Reef Raider (NetEnt)

NetEnt love’s to push the boundaries and they have certainly managed that with one of their best new slots 2021. This game features a 7x7 grid of top paying symbols that can create wins in clusters rather than landing along the usual pay lines.

The theme is an underwater world filled with the treasures that submerged over the years as ships lost their way in the unforgiving oceans. There’s a cool 8,500x prize up for grabs along with a load of cracking features.

The Paying Piano Club (Play'n GO)

For a game with one of the best soundtracks around and big cash prizes to boot, you need to take a look at this Play’n GO title. It’s only a few months old but it looks set to go down in the history books as one of the best.

There’s a curiously small reel setup with just 3 reels and 3 rows in play. But that doesn’t stop the game from dishing out some regular wins. There’s also a nice free spins round with some hard-hitting multipliers. A great adventure is waiting to be had on this saloon bar classic.

Voodoo Magic (Pragmatic Play)

The dark underbelly of the far-flung islands of the world comes to life in this 5 reel, 4 row hit from Pragmatic. The volatility is incredibly high so don’t expect these magic potions to go handing out regular little wins to help you out.

There are 40 paylines during the base game that are capable of dishing out the occasional massive prize. But the place you want to be is the free spins round where you get to select from three special gifts to help boost your chances.

Hyper Strike (Microgaming)

Microgaming and Gameburger have teamed up to bring you this great game with an old-school vibe. If big and bold is your thing with simple game mechanics, then this top new production could be right up your alley.

This bright pink fruit machine features some classic symbols and a few added extras on top just to make it extra special. There are 5 reels, 3 rows, a load of free spins plus an incredibly valuable multiplier up for grabs.

Chicago Gold (Microgaming)

Another team effort from Microgaming and a small studio. This time it's the turn of PearFiction. The game takes us back to a time of prohibition but with a huge twist. Instead of the dimly lit bars and subtle secrecy we’ve now got bold features and huge neon lights.

We've got big bosses, glamorous ladies as well as plenty of cops and gangsters coming together to create an epic adventure. There are free spin features, big cash multipliers, loads of hard-hitting symbols as well as a huge jackpot up to 5000x. It all takes place over 5 reels and 40 pay lines and is quickly gaining traction as one of the best slot titles around this year.

Eye of the Storm (Pragmatic Play)

Pragmatic are playing host to this new title developed by the Reel Kingdom studios. This is another ancient Egypt themed slot that falls in line with the extremely popular Eye of Horus game.

There are only 10 pay lines on this game but what it lacks in megaways-style mechanics, it certainly makes up for with its expanding wild symbols and free spins round. And don't forget to look out for those transforming symbols that can turn themselves into any of the others to create some top wins when you least expect them.

San Quentin (Nolimit City)

There’s seemingly no end to the imagination of the modern slot designers and this is certainly true of the team at Nolimit city. This prison theme slot - that’s right, you heard correctly - takes place behind the bars of San Quentin penitentiary. The winning symbols are various items that you might find on the inside such as lighters, shivs and toilet paper!

It has some nice walking wilds and split symbols that can create some enormous wins. This slot is all about the huge payout and that’s why you will need plenty of patience and a decent bankroll to see you through this highly volatile journey. The top payout, when it does land, is up to 150,000x.

Rome: The Golden Age (NetEnt)

There’s a long list of classic Roman-themed slots and this one promises to break the mould. It’s fairly standard at first glance with its 5 reels and 20 pay lines. But you soon get the feeling that there’s something a little special about this game.

It’s not just the free spins and multipliers that have got your back on this slot. There’s an amazing bonus meter that charges up during the free spins round. Fill it up completely and you’ll see your prizes multiplied by up to 1000x.

Why you should play new slots

One of the great things about modern-day slots is that they make use of the very latest technology. Slots that have been around for a long time generally feature some of the most basic mechanics. But the ones you see today at the latest casinos are jam-packed with the most intriguing ways to win a top prize.

There are often special bonuses upon launch

Studios want to hit the ground running when they bring out a new game and to make a big impression on their audience. And one of the best ways they can do this is to generate some cracking bonuses exclusively for that title. You can often find free spins up for grabs as well as bonus cash that can be spent playing these games.

New and exciting features

The latest games at the best new slot sites Will be constantly pushing the boundaries when it comes to bonus features and their mechanics. You might think you have seen it all during your time playing slots. But believe us when we say that the sky's the limit and software designers constantly amaze us with their inspired designs.

Great design and gameplay

If you have played any of the very latest titles then you will know that the audiovisuals are increasingly becoming more and more intricate. The skilled teams behind today's slots have the very best technology at their fingertips. And they’re not afraid to use it! 3D, virtual reality and AI are making their way into the arena so watch this space.

Why you should favour older slots

Some slot fans are simply sticklers for a classic. You may be of the impression that if it ain't broke don't fix it and if that's what you prefer then that is fine. There is a huge back catalogue of games available at the top casino sites listed here on this page. They don't just feature the very latest games - they will have a ton of the golden oldies as well. Older games are easier to get your head around and generally have a lot less going on. And this is great if you simply want to sit down and hit the spin button without reading up about a ton of features.

The classics never get old

A classic is a classic for a reason. It struck a chord with slot fans and managed to do so without the fancy wizardry employed by today's latest titles. There are games that enjoy huge popularity and do so with the most basic mechanics. This is a testament to the top designers at some of the very best slot production companies in the industry.

Familiar features and symbols

It can be incredibly frustrating sitting down to enjoy a few spins on a slot machine when you are faced with a ton of features and symbols that you just don't understand. Some people like the challenge of figuring out what is going on while others prefer to know that the game layout and everything it has to offer will not cause them any confusion.

You don't have to learn how they work

And it’s not just the features and symbols that can have you tearing your hair out if you're not familiar with modern mechanics. The new ways to win prizes across multiple lines and in various directions can be baffling at first. And we also have cascading reels with cluster combinations. These can have even the most seasoned slot pro scratching their head for a while.

New slots with progressive jackpots

Some of the latest games come with some incredible prizes. And the top payout of all is of course the jackpot. Some of the games go one step further. And they produce a progressive prize that can release some life-changing sums of money.

What is a progressive jackpot?

A progressive jackpot is a prize that pools together a little bit of money from each of the players to contribute towards one big win. This may occur on 1 game at 1 casino only or it can take place across multiple titles and various casino sites. The latter will produce some of the most eye-watering jackpots that you will ever see.

What makes a great new slots game?

So what is it exactly that makes new casino slots so fantastic? Well, it's a combination of things. And when they all come together at the right time they can create an amazing game. Let's take a look at some of the elements that are involved.

Unique features

During the base game, it's always nice to see some added extras that can help boost your balance. And the best way to achieve this is by using some clever little features. Wild symbols and scatters are 1 of the tried-and-tested methods on most slots. But new, modern games will have other things in mind. Meters that fill up to generate bonus features is just one of the ways they can do this. As well as symbols that stick and respin the reels, for example.

Bonus games and free spins rounds

Game producers know how much slot fans love a bonus round. And one of their favourites is free spins. These generally create bigger wins than during the base game and don't make a dent in your balance in the process.

Fresh and clever design

Grainy graphics are a thing of the past and modern slots make use of the very latest audiovisual technology. 3D animations are becoming incredibly popular with new games which make certain elements really come to life.

Smooth gameplay in both desktop and mobile

Many of today's slot players like to spin those reels while out and about. And the best way they can do this is to play on their mobiles. In the past, there have been issues with the quality of certain games when they transport over to smaller devices. But this is quickly changing and now all modern games are optimised across all screen sizes and operating systems.

Moving from Flash to HTML5

If you have been playing slot games for a while then you will have noticed that flash is no longer used at the latest casinos. This tech change has had a big influence on the gambling industry but in the end, it has been a change for the better.

Adobe Flash is no longer available

Adobe discontinued the use of Flash as modern browsers no longer needed this facility. It became a security risk over the last few years and this has been corrected with the implementation of HTML5.

The UK's best new slots sites 2021

New online slot sites are the talk of the town and today's players are actively seeking out the very latest casinos where they can play the top new releases. Here on this page, you will see some of the very best casinos in the industry that offer new slots UK.

Bonuses to use on new UK slots

New online slots are available to play using bonus cash and free spins released by casino sites up and down the country. Rewarding new players for signing up for a new account is nothing new and the deals keep on getting better and better. There are many ways that a casino can thank players for joining them so let's take a look at some of the most popular.

Free spins

One of the bonuses that lots of fans love to receive when signing up to a new slots site is a free spins promo. They usually feature the latest slot titles and also offer the opportunity to walk away with some of the winning cash. It’s possible that some offers will require you to make a deposit before the casino releases this top gift. However, there are some that will simply dish out the free spins for doing little more than signing up for a new account.

If you are interested in landing yourself a free spins deal then you will want to check out the list of trusted sites presented here on this page. The number of free spins up for grabs will vary from site to site but it's not unheard of to get your hands on hundreds of them if you play your cards right.

No deposit bonuses

As we said, it is possible to find a new slot sites no deposit bonus. And this is definitely one of the most coveted deals around. Getting hold of your bonus cash or free spins is fantastic especially when you don't have to risk any of your own cash in the first place.

A no deposit deal will simply come your way courtesy of the casino when you complete their registration form. The size of the offer will be significantly lower than that of a deposit deal. And there will almost certainly be some rules in place as with any signup offer. You must read the small print in the terms and conditions to see what wagering is placed on any winnings that result from bonus cash or free spins. Choosing the right deal for you is incredibly important so read through the details before opting in.

Deposit based bonuses

If you are keen to get your hands on a more lucrative deal than the one mentioned above, then should look at some of the deposit deals around at the moment. Parting with a little of your own cash can see the bonus amount skyrocket.

Many casinos are happy to match whatever you pay in for your first deposit. This will have a limit, naturally, but sometimes the limits can be very high. it's not impossible to find a deposit match that goes into the thousands.

But remember, any bonus cash that you receive for signing up for a new account will come with some stipulations. The more money you receive, the harder it will be to complete the wagering requirements at some sites. Wagering can be 10x or it can even be up to 70x. It all depends on the brand so check the T&Cs carefully to make sure you understand the deal.

New mobile slots in 2021

New slot sites can no longer rely on desktop-based games. The modern player wants to be able to take that casino with them wherever they go. This means optimising everything about the site to ensure that it looks great on any kind of device.

It is very unlikely that you will find a new casino brand that does not offer a dedicated application or at least an optimised browser site for mobile phones. But if this is important to you, then you should check to make sure that the brand has this option for players before you sign up for an account.

Payout rates for new online slots

The size of the house edge can be top of the list of priorities for some players. And the way they find this out is by looking at the RTP.

What is RTP?

RTP stands for return to player. It is given as a percentage figure to show the amount of money that comes out of a casino game or slot compared to the amount of money that goes in. This percentage is calculated over an enormous length of time for slot machines especially. It is a legal requirement for a casino game to show that eventually a certain amount of cash will always be returned to the players.

However, this figure takes into account an incredibly large number of plays when referring to slot machines. It will include the sessions of many different players on the same game. So you cannot use this as a guarantee for how much you will eventually win.

The payout from any game is completely random.

Our review process for online slots sites

There is a lot to take into consideration when reviewing a new casino. It's not enough to simply flick through the website and decide if you like the look of it. You need to dig much deeper to uncover all there is to know about that business. Our expert reviewers spend hours, sometimes days, sifting through everything there is to know about a casino. We only represent a site here on this page when we believe that everything is up to scratch and that they can offer you the very best service.

Let's take a look at some of the fundamentals that our experts delve into when deciding how good a casino really is.

Steady stream of new slots releases

It used to be the classic casino games that got fans excited. But over the last few years, slot machines have taken their place as the number one game available when gambling online. The simplicity and potentially big payouts combined with a whole host of themes really appeal to millions of fans all over the world. And for this reason, new game producers are creating Innovative titles almost every day.

When deciding how good a new casino brand is, one of the things we look at is how regularly they update the library of slots. With such a huge range available on the market we want to know that a casino takes this area of their business seriously. It shows just how much they care about their players.

Free demo play

Having loads of new slot titles is an incredibly important thing to offer. But we also like to see a casino that allows its players to check out demo versions when they want. Getting to grips with a new title that might have complicated features, for example, can take some time. So it's nice to be able to practise a game before you part with any cash.

New free slots can be incredibly intimidating at first glance so it's imperative to make players feel as comfortable as possible. But remember that when playing a demo version of any game, you will not be able to walk away with any of the cash that you win. This can be incredibly disappointing if you see a huge win come in while playing for practice cash.

Large selection of game providers

And all of these small new games don't come from the same software company. There are loads of fantastic game producers in the industry and the list keeps on growing. Talented designers are coming up with new ideas all the time and trying to break into the slots market.

Many of the smaller studios become part of the larger game companies eventually and this helps to keep things more organised. We love to see a casino that brings in a selection of top game providers to keep their titles fresh. It's all about offering the players what they want and new slot games from a variety of producers is definitely one of those things.

Good welcome offer

New slot sites with a free sign up bonus are the perfect way to attract new customers. There is a huge variety of casino sites available online so it can be very difficult for them to stand out from the rest. One way the casino brand can catch the eye of potential customers is to hand out some free cash or spins on the way through the door.

There aren't many sites that don't offer welcome bonuses as operators know how popular they truly are. They can come in a variety of forms. And as we saw earlier, some will require a deposit to be made while others are a little smaller and can be yours for doing little more than signing up for a new account.

Slots games that work in mobile and tablet

Finally, for us, it is imperative that a casino does everything it can to offer the very latest action across all devices. Many players love to access the casino accounts while out and about and perhaps spin the reels on their favourite slot machines.

A new casino probably won't last very long in today's climate if they don't have the latest mobile technology implemented in their operating system. More people use mobile phones to access the internet than via laptops and desktops so it stands to reason that mobile gaming is the future of this industry.

Things don't stand still for long in the world of slots. New games come along with clever features and top ways to arrange win lines all the time. And thanks to some of the incredibly talented designers, slot games just keep getting better and better.

And as more and more people find themselves playing slots online the demand from the player is also increasing. In the past, a developer could get away with producing a very basic game and hope for the best. However, this is no longer the case as punters are becoming incredibly discerning. They want the very best technology at their fingertips. And if a slot producer won’t provide it, then they will look elsewhere.

Below we are going to take a look at a couple of the new trends that we consider to be the future of the slots industry.

More focus on mobile gaming

We’ve said it before and we’ll say it again, the future of the online slots market lies firmly on the mobile platform. It's hard to think that we used to have to wait to get home and fire up the PC before we could start playing our favourite games. The wait seemed like forever but now that is all set to change.

The technology that powers mobile phones is increasing at an amazing rate and the clever software companies responsible for the top slot titles are busy keeping up with these innovations. More and more time and money is being invested in this area of online entertainment. And it won't be long before 3D rendering is a standard offering. And not too much longer before we can immerse ourselves in the whole gaming experience thanks to virtual reality.

When physical slot machines first hit the scene their features were fairly limited. You could expect a few nudges here and there but apart from that, there was nothing much else to write home about.

Bonus games and features came along much later and when things moved online, the new way of playing lent itself to some incredible new bonus features. Free spins are now a firm favourite and have been for quite some time. They will always be one of the most sought after features in any game.

However, all the bonuses such as pick-a-wins, for example, are now becoming quite standard on some of the best slot games. Then we also have wild symbols that can perform amazing tricks and stack across the reels. After that, you will also find bonus wheels that can offer a host of prizes and various mini-features as well. The possibilities are endless and we can't wait to see what the clever guys behind the scenes will come up with next.

The software developers

New online slots would not be possible if it weren't for the incredibly dedicated and talented coders and artists. Looking back at some of the previous products on the market it really is hard to believe that we have arrived at this point. Some of those previous games are now unrecognisable. This is thanks to the amazing enhancements that the software producers have come up with.

It's only fitting that we take a closer look at some of the best companies working tirelessly behind the scenes. There are of course many more but the following are the most dominant names in the industry.

Net Entertainment

NetEnt has been in the game for a long time. They are one of the pioneers of the online casino industry and are responsible for shaping the landscape. They have produced some of the very best classic casino games that we all know and love. These include video formats of table games such as blackjack, roulette, baccarat and more.

They also have a fantastic live casino offering. So all of the above games and more are at your fingertips when you choose to play their titles. But their real forte lies in the production of incredible slot games. They have some amazing progressive jackpot slots as well as a host of different themes and Innovative features and bonuses.

Microgaming

Microgaming is based in the UK and is responsible for producing the very first online casino. Being there since the start has allowed them to gain a real insight into how players like to interact with their games and know exactly what they like.

You won't find many casinos that don't offer Microgaming titles as part of their inventory. People seek out games by this slot producer as they know that they will be getting the very latest technological advancements and greatest gameplay available. They too produce table classics along with an amazing range of live games as well. These include some incredibly entertaining versions and twists on old favourites.

Pragmatic Play

These guys not only produce some great games but are also a big name in creating the software that powers many online casinos. Their tech solutions work tirelessly behind the scenes to make your gaming entertainment possible at the click of a button.

They produce everything from bingo to slots and live games as well. And being such a reliable provider has gained them an amazing reputation in the casino business. They are licensed to provide their products in over 20 jurisdictions and this shows you just how trustworthy they really are. You know you are in safe hands when you play anything powered by the Pragmatic brand.

Play'n GO

This company was created in Sweden back in 1997. They produced games for some of the other top software companies for a while. But then went out on their own in 2004 as an independent. They don't have as many games in their library as some of the other big providers but the ones they do produce really are some of the best around.

Play’n GO games are available in loads of different languages which makes them a truly international offering. And it has given them a fantastic reputation throughout the world. Everything they produce is of the highest class and is optimised perfectly for the mobile market as well.

Thunderkick

Staying in Sweden, we find another top game studio that goes by the name of Thunderkick. It is a small independent group of designers who produce some of the most technically advanced games on the market.

They started back in 2012 with just two guys working for the company. But since then, they have grown to become one of the most respected studios. They provide amazing games to online casinos in various jurisdictions.

Payment methods for online slots

One of the most important aspects of any casino brand is its ability to get money moving in and out of that casino quickly and safely. It doesn't matter how good your games are or how flash your website is. If players can’t make deposits and withdrawals in a convenient and secure way, then the business will have a very short shelf life.

When online casinos first came onto the scene, there were very few options. But that started to change as various companies around the world worked to find viable solutions.

Some are much faster than others and this is due to the technology that powers the products. The great news is that most casinos, especially in the UK, will not charge for withdrawals or deposits. But you will need to check this information with the casino before signing up. Let's take a look at three of the top ways to pay at the casinos we represent.

e-Wallets

If you are looking for the very fastest way to get your money in and out of a casino, then you will need to consider an e-wallet. This amazing invention has been a real game-changer for not just the casino industry But e-commerce in general.

It first started to take shape with companies such as PayPal. They were striving to provide online traders with a way to accept payments from customers around the world. Before this, the only option was to accept card payment and this came with its costs. For smaller traders, it was an impossible cost to absorb. So along came companies such as PayPal, Skrill and Neteller to save the day.

It's a very low-cost, convenient way to send and receive money in various currencies around the world. And it’s actually the fastest withdrawal method available at top casinos online.

Debit/credit cards

Anybody that has a bank account will probably have a debit card as well. And these can be used to get funds directly from your bank into any casino. Or to pay for products in-person and online. When online casinos first appeared, many players were sceptical of sharing their card details. And this led to the rise of e-wallets as we mentioned above.

However, using this method is incredibly safe and should have your money moving in just a few hours. Making a deposit is usually instant but getting your winnings back out again can take a couple of days.

In the UK, credit cards are no longer an option if you are making a casino deposit. Changes to the law over a year ago put an end to this method of funding online gambling entertainment.

Pay by phone

This may sound like a strange concept. But it is possible to use the money on your mobile phone top-up credit to pay for a casino deposit. How it works is very simple. You go to the cashier section of your casino account and select ‘pay by mobile’ to make the transfer. Funds that are sitting on your top-up credit can be used for games as well.

There are a couple of drawbacks to this type of payment service though. You can only play with small amounts of money as the maximum transfer is just £10. And this can be a huge hindrance if you are looking to splash a little more cash. There’s another downside to this method. And that is that it is not possible to withdraw winnings back to your mobile top-up credit.

There are a couple of big names that produce this payment service. And you will usually find both of them available at most casino sites. Look out for the Payforit and Boku logos when searching for the payment options at your chosen casino.
