The Best Slots to Play Online in 2020

UK slot players are always looking to gain a little advantage – this can be crucial in a game where luck plays such an important role. Gambling veterans look at several things when they pick their top slot to play. The graphics and the visual effects should have a very minor role in your decision – you should look at the potential payouts you can get from the game. In the table, we have listed our top 5 best online slot games for 2020.

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 slot games, 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!

• Top 5 Best Rated Online Slots

• Cleopatra Slot

  Cleopatra is a very fun and popular slot, with 5 reels and 20 winning paylines. Created by IGT, Cleopatra Slots will take you on a trip down the Nile and right in the heart of Egypt. This mystery-filled slot is extremely popular in land-based casinos all over the UK, so it was only natural for it to be at the top of the best online slots, as well. Cleopatra I and II are pretty much alike, with an RTP (return to player) of 95.02%. The bonus rounds are triggered by 3 or more Sphinx symbols and consist of 15 free spins. As you may already know, free spin slots have great potential in terms of possible profit, especially ones that grant multipliers during these free spins. The Cleopatra symbol is wild and can substitute all symbols, with the exception of the Sphinx. While doing so, the wild symbol also doubles your win. During the free spins bonus, should you hit another 3 Sphinx symbols, 15 more spins will be added, with a maximum of 180 free spins to be won. Also, 5 Sphinx symbols pay 100 times your initial bet.

• Gonzo’s Quest

  When you play Gonzo’s Quest with real money, there are several ways in which you can boost your winnings. For starters, there are seven different Mayan themed symbols. Line up 3 to 5 identical symbols on a payline and your line bet will be multiplied by a certain amount and paid to you. Therefore, the higher your bet amount, the larger the payout. The highest paying symbol is the blue and gold face, which pays x2500 for 5 of these. One of the unique features of this game is the Avalanche feature. This sees symbols fall into place rather than spin. When you get a win, the symbols explode and more fall from above to fill their place. This not only provides numerous chances to win from the same spin, but each consecutive Avalanche will see the win multiplier increase, up to a maximum of x5. The game also has a wild symbol, which substitutes for all others, therefore providing more chances of getting a winning combo. Whilst the slot does not have a bonus game, it does feature free spins, or “free falls”. Line up 3 golden free fall symbols and you are awarded 10 free spins, with even bigger multipliers for consecutive wins.

• Zuma Slots

  Another UK all-time favourite, Zuma Slots are inspired from the addictive Popcap game with the same name. Just like all the popular land-based slots in the UK, Zuma features 20 paylines on a 5-reel slot machine. Three frog symbols trigger the bonus round. The same enticing sound effects of the Popcap game will announce the beginning of the free spins round. You have to shoot one of 4 Tiki bosses to award you a certain number of free spins. Once the free spins are over, you have to shoot another one of the 4 bosses to reveal a multiplier on your free spins win. The Zuma symbols substitute all other symbols in a wining combination, except the Frog, and they multiply your win by up to 10 times. The game offers a Gamble feature, which you can use to increase your profit after every win. This feature can boost your winnings by a maximum of 10 times and you can collect all or just a part of the winnings, while gambling with the rest. There is also an Autoplay feature and you can set it to 50 spins and you can just sit back and enjoy the ride.

• Monopoly Slot

  Perhaps the most famous board game in the world, Monopoly, can also be played as a slot machine today. The popularity of this slot is mainly due to the bonus games that can be triggered by certain symbols. The graphics of the Monopoly Slot are not as sophisticated and impressive as the previous slots that we have reviewed, but more simple and loyal to the style of the original Monopoly game. The Pass “GO” Bonus is packed with free rolls, like the ‘Spin until you win’ feature, multipliers and more. First, you have to pick a card to see how many shots you get at the Bonus round. While 3 or more Bonus symbols will trigger the Pass “GO” Bonus, 3 Instant Bonus ones will trigger an Instant Bonus round. Wild symbols may substitute all other symbols in winning combinations, with the exception of the bonus ones. Landing on “GO” will win you a 2X multiplier and 5 Monopoly symbols will multiply your bet by 2.000. One of the few online casinos that offers Monopoly Slot is 888 Casino, with a pretty high RTP of 95,02%.

• Double Bubble Slots

  The Double Bubble is another fun slot with 5 reels and 20 paying lines. While you can play with your bet per line from 1p to £10, I strongly recommend playing all 20 lines, to make sure that you don’t miss out on anything. The maximum payout is 30,000 times your coin size, which is a pretty generous payout in my book. The Double Bubble symbol is wild and may substitute any other, except the bonus bubble. If you hit 5 wild symbols on a payline, you will win 20,000 times your bet per line. The total win on one spin is awarded according to the base paytable and multiplied by the Bubble Line multiplier – which is 22, if you play on 20 lines. The Bubble Bonus game is triggered by the bonus bubble symbol on lines 1, 3 and 5. During this round, you will have to pop one of three balloons and you will win the corresponding multiplier hidden inside. The overall payout percentage (RTP) is 96.02%, but it could vary from 95.75% to 96.24%, which is not at all a bad profit expectancy.

What Are The Best Progressive Jackpot Slots?

When we are trying to rate the best online slot games, the elephant in the room always turn out to be jackpot slots. Progressive networks are much-loved by online slot players, but the huge prizes have a cost – the base games usually give out worse payouts than their counterparts. 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!

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.

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.

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 should give you the option to play from your phone wherever and whenever you like. 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 where you can play them on the go.

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

If you are wondering whether to play on the downloaded platform of the casino 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 them in Flash mode. If your Internet connection is low, it is recommended to use the download version.

• Use the download version if your connection is under 1 Mbit/s
• For connections over 1 Mbit/s, the loading time of the Instant games is relatively low
• Use on mobile devices with WiFi connections and native apps

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 – Return to Player rate – of an online slot shows the potential payouts it will award. Slots with higher RTP rate are highly sought after, as most 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. To help you out, in the table below we have prepared a list of the best paying online slots in the UK.

New Slots on the UK Market

There are new slot titles coming out all the time, so some of our findings may have changed by the time you read this. However, we always strive to do our best and keep up-to-date with all the new findings in the industry.

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 play:

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 (return to player) when playing slots. However, it determines how much of your investment will be returned to you, under ideal circumstances. Online slots 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.

3. Play only for the highest jackpots:

A good advice for online slot 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. 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. 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. This is why we recommend using PayPal and Moneybookers to manage your funds at online casinos, as such data doesn’t get divulged or transmitted to the respective casino operator.

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 PayPal – that’s why we keep a running list of PayPal slots that you can enjoy with a quick and safe deposit.

Advantages and Disadvantages of Online Slots Compared to Other Casino Games

• Plus Dynamic gameplay Higher payouts Huge jackpots No skills needed 100% Bonus contribution Great variety of games
• Minus Higher potential addiction Not engaging, only spin needed No live game version

In terms of gameplay, there could not be an easier and less engaging game than slots. The only thing you need to do before you start playing is to set the number of 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 lines or until feature. 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. 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 games.
