Of course, things can change quite swiftly in the world of online slot games, since there are new titles coming out all the time. In the next section, you can see detailed info about some of our former top 5 picks and what made them special – but the current 2020 list will be updated constantly with the latest online slots games that include random number improvements, so you might notice some differences! We are dedicated to bringing you slots only from the strogest contenders at the title of the best online casino UK players can aspire to play at!

What Are The Best Progressive Jackpot Slots?

When we are trying to rate the best online slots, the elephant in the room always turn out to be jackpot slots. You have always heard about games like Mega Joker, Break da Bank or Jackpot Giant that have become popular throughout the years. Progressive networks are much-loved by online slots players, but the huge prizes have a cost – the base games usually give out worse payouts than their counterparts. Any jackpot game aims at attracting customers with lucrative rewards. They are programmed so because a portion of each and every wager goes to the huge jackpot pot. That’s why we have to use different criteria when we try to rank the best jackpot slots. You can see the current top 3 list for 2020 down below!

Mega Moolah by Microgaming

The main attraction of this game is the progressive jackpot. Slots bonuses during the game can improve your user experience a lot. When the bonus game is randomly triggered, you have the chance to spin the wheel without any wagering requirement, which holds the four different jackpot prizes.

The Mega Moolah slot are offered by the award-winning software provider Microgaming
Largest paid jackpot £13 million
Average period around 122 days
Average Payout £2.1 million
Average increase £12,300/day
Recommended Casino Betway

The most appealing of these prizes are the major jackpot, which starts at £10,000, and the mega jackpot, which is guaranteed to be at least £1million. The mega jackpot regularly builds to several million pounds. Jackpot payouts always provoce big interest among players.

Mega Fortune by NetEnt

Among the jackpot games, The Mega Fortune Slot by Net Entertainment presently holds the Guinness World Record for the biggest jackpot ever paid. We can consider this game as the jackpot giant on the market.

Mega Fortune is a very popular progressive jackpot slot
Largest paid Jackpot £15,143,600
Average period around 70 days
Average payout €4.2 million
Average increase 60,000€/day
Recommended Casino Grosvenor

This is not the first time that this slot is in the spotlight, as it was the holder of the last slot payout record, with another impressive win: 11.8 million euro. By the average daily increase of 60,000€, I think it is safe to say that this is one of the most popular online slots in the UK.

Beach Life by Playtech

Beach Life is the record holder among Playtech slots.

This Playtech slot offers a huge progressive jackpot
Biggest jackpot £5,416,245
Average period around 165 days
Average Payout $2.25 million
Average increase $13,600/day
Recommended Casino Ladbrokes

The happy slots player took home a staggering 8 million dollars. Beach Life is by far the largest jackpot slots offered by Playtech at Ladbrokes Casino. Of course, the probability of winning this jackpot is lower than on other slots, but you can also try some of the Age of Gods Slots, with huge progressive jackpots.

The Best Mobile Slots of 2020

The best casinos for online slot machines and new games on the market should give you the option to play from your phone wherever and whenever you like. This will improve your slots experience while playing. Software developers are always looking to optimise their portfolio for mobile play, so the top slot games should be available with optimised interface. You always get the exact same payout percentages and volatility as on the desktop version. In the table below, you can see a list of the best online slots to play on a mobile app along with the top platforms and slot sites where you can play them on the go.

Slot for Mobile Compatibility Slot Software Best Casino Secure Link
Cleopatra Android, iOS IGT LeoVegas Play on Mobile
Gonzo’s Quest Android, iOS NetEnt Casimba Play on Mobile
Game of Thrones Android, iOS Microgaming Karamba Play on Mobile
Mega Moolah Android, iOS Microgaming Betway Play on Mobile
Jack and the Beanstalk Android, iOS NetEnt Betvictor Play on Mobile

Download or Instant Play? It All Depends On Your Internet Connection

If you are wondering whether to play a slot game on the downloaded platform of the casino sites or directly in the browser, there is mainly one factor to take into consideration before deciding for one or the other: your Internet connection. The differences between the two modes are insignificant, most of the times, so you only need to decide if you would rather download and install the software and cut back on the loading time of the games or play slots online in Flash mode. If your Internet connection is low, it is recommended to use the download version.

Native apps are recommended for smartphone or tables, while using a WiFi connection. The connection from your mobile Internet provider may be slower and even limited. The problem is that while for Android and iPhones or iPads there are casino application available for download, Blackberry and Windows Phones users need to use the web app most of the times.

The Best Payout Percentage in Online Slots for the UK

The RTP of an online slot shows the potential payouts it will award. Casino slots with higher RTP rate are highly sought after, as most slots players try to improve their odds of winning. On its own, this theoretical payout percentage does not give you enough information – you need to consider other factors such as the variance (or volatility) of the game. The slot variance shows what behaviour you can expect from the slot – slots with low variance will earn you frequent, but small, wins, while slots with high variance can net very high wins, but only occasionally. Generally, to get the best payout in online slots you need to look into the details. You can always find some slots for free to test the slot bonuses features too. To help you out, in the table below we have prepared a list of the best paying online slots in the UK.

Top Slots Payout % Slot Volatility Secure Casino Link
Jack Hammer 97.00% Low Play at Casimba
Lucky Leprechaun 96.83% Medium Play at Betway
Immortal Romance 96.80% Medium Play at Betvictor
Dead or Alive 96.80% High Play at 888casino

How to Win on Slots: Tips for Real Money Play

If you feel that you are ready to try one of the best casinos to play slots, then you should still prepare yourself – you will be wagering real money after all! Here are three important tips for real money slot game play at the best slot sites:

1. The strategy of progressive betting:

A popular system for playing online slots is starting with the lowest bet and increasing it every 50 spins. If during these spins no free games or big wins are awarded, it is time to raise the bet per payline. This way, when you hit something on a higher bet, it will more than enough to compensate for your investment. However, given the high variance of some slot machine games, this strategy has its drawbacks, as it could be a while before you hit a big win.

2. Play on slots with the highest payout percentage:

Few players acknowledge the importance of the RTP when playing slots. However, it determines how much of your investment will be returned to you, under ideal circumstances. Online slots (and some classic slots too) usually have an RTP of over 90%, but only some of the best slot payouts will reach more than 95%.

It is also important to remember that the RTP is slightly lower for jackpot slots. The lower payout rate is due to the fact that part of the money you wager go into the jackpot. And given as jackpots are different sizes and different percentages of them can be won, the expected profit may vary. You can also check for some free slots to practice first and make a better strategy in advance.

3. Play only for the highest jackpots:

A good advice for online slot game players is to play only the highest jackpot slots. Of course, the bigger the jackpot, the bigger the win, but that is not the only reason. A small prize means that someone has already hit this jackpot recently, which is not likely to happen again too soon. A huge jackpot, on the other hand, means that the winnings are piling up and there is a bigger chance of you winning it. It is almost impossible to calculate the exact probability of you hitting the jackpot, but the bigger it is, the bigger the profit expectancy becomes. A free slot game can offer you the chance to examine carefully the gameplay features. In the following paragraphs, I will give you facts on some of the biggest wins on famous slots, as well as average periods and payouts.

Why You Should Deposit Using Paypal and Moneybookers When Playing Online Slots

When you decide to start playing slots online, safety should always be your number one priority when you enter the online slots sites. The safety of your personal and banking details and passwords should always be in good hands, as all information that is transmitted over the Internet can, at one point, be intercepted. You should also be able to choose convenient deposit limits. This is why when it come to play online slots, we recommend using PayPal and Moneybookers instead of a debit card to manage your funds at online casinos, as such data doesn’t get divulged or transmitted to the respective casino operator. Besides, those banking options come with no withdrawal restrictions. This makes them perfect for playing the top online slots at the best sites for casino.

Safety measures for the most popular online banking methods, Paypal and Skrill

Of course, sensitive data needs to be transmitted, that cannot be avoided. However, with these electronic wallets, the information remains in the safe hands of organisations with huge experience in the field. Of the two payment methods, most casino players seem to prefer to rely on PayPal. This is simply the biggest eWallet out there, and most people tend to rely on it for their online transactions – if a slot site is partnered with it, this is also considered as a positive sign about its reliability. However, not all operators use the services of a payment method such as PayPal – that’s why we keep a running list of PayPal slots that you can enjoy with a quick and safe deposit.

In terms of gameplay, there could not be an easier and less engaging game than slots. Slots offer amusing features. The only thing you need to do before you start playing is to set the number of max lines to play and the bet per line. Then all you have to do is press the ‘Spin’ button or choose the ‘Autoplay’ option for up to 100 pay lines or until feature. Some table games like roulette can also be considered a fairly simple game, but with Video Poker or Blackjack, a more strategic thinking is needed to choose the course of the game, which can make the difference between a win and a loss.

The indisputable advantage of playing online slots is the opportunity of hitting a huge jackpot, which can even reach millions, as opposed to the classic casino games like blackjack or roulette. While playing slots, the entertainment is guaranteed not by challenging gameplay and strategic thinking, but by means of great graphics and sound effects. Also, video slots often include great animations, videos and interesting bonus rounds that are comon across many real money slots. Some even offer exclusive customer support. Lots of new and innovative online reels can be found at new online casinos, who often team up with newbie software developer companies. These devs typically have their finger on the pulse of the online gaming industry and create cutting-edge slots products with excellent graphics, storytelling and features.

Slots however also have few drawbacks, when compared to the classic casino games. There are no live versions of this game, although Evolution Gaming have already experimented with the idea. Also, the potential addiction is higher with slots than the other best games.

Casino Player Questions About Slots

Here we will answer the most common questions that casino players have when it comes to online slots.

✅ What Is the Best Online Casino to Play?

'Best' is a highly subjective term, especially when you consider how quickly things change on the internet. For fans of online slots, there are a lot of factors to keep track of, like the slot bonus, the game catalogue, the mobile performance, the payment policy and the biggest jackpots. Of course, we keep our list of the best slot casinos constantly updated.

✅ Which Online Slots Are the Best?

To answer this question, you need to have played slots a lot. Different players consider different factors, but most commonly you need to keep track of the RTP rate and the slot volatility of the game. Most players also have a preferred software studio – and you should never forget the casino bonus, which is usually perfect for slot play. We consider this and much more when we pick our top 5 slots to play online.

✅ Which Online Slot Machines Pay the Best?

You would often find players on the hunt for loose slots, especially at land-based casinos. Another favoured superstition is the hot and cold slots myth. Modern RNG modules make such tactics obsolete – unfortunately. When we try to filter the best paying online slots in the UK, we consider the officially published data that is verified by independent institutions such as the UK Gambling Commission. But we also run our own tests in demo and for real at some of the best online real money casinos.

✅ How Do You Pick a Winning Slot Machine?

You don't. There are never any guarantees that you will find a slot machine that is sure to win. However, you can improve your odds by playing smart. Check all the available data, and take the time to pick just the right slot. You can refer to our Slot Tips and Tricks for more information.

✅ Can You Make Money Playing Online Slots?

Of course. It all comes down to luck, but the chance to win is guaranteed – if you are playing at a safe and verified casino. If the online casino has valid licenses and has passed the inspections of the UKGC, then all slot games are guaranteed to give a certain amount of winnings. The very same applies to mobile play – if you take care and pick only the best slots app, you won't have any problems with scams.

✅ Which Gambling Games Are the Most Popular?

Slots are currently the most popular casino games in the UK and the rest of the world. The statistics for 2020 show an overwhelming advantage of slots compared to all other casino games. Of course, this doesn't automatically make slots the best online casino games – they have their own advantages and disadvantages when compared to other popular casino games. However, as slot fans we can safely say that they are the most fun!

✅ What Slots have the Best Odds of Winning?

This is an easy one - those that have the highest RTP listed. Return to Player rate - or as we prefer to call it, payout percentage - shows what winnings a game will give in the long run. The higher the RTP rate, the higher the odds of the machine paying out. However, slot players are much more interested in the odds of hitting a special combination - usually the top prize. However, those are much harder to determine since modern-day online slots run on a complex RNG software, and studios and developers are loathe to give out any details about it.

✅ Are online slots rigged?

Online slots that are developed by certified software providers cannot be rigged. They are subject to regular audits by third-party testing agencies. Same goes for all slots that are featured at a certified online casino. So, to stay safe, stay with licensed casinos and established slot developers like Microgaming, NetEnt, Playtech and IGT, otherwise you don't have a guarantee that the slot isn't rigged.

✅ Which are the best online slot machines of all time?
