Best Online Slots UK | Top Slot Sites in 2024

What Are the Most Popular Variations of Online Slots?

There are 4 popular slot game types you’ll find online:

1. Progressive slots
2. Branded slots
3. Video slots
4. Classic slots

Progressive Slots

Progressive slots, also known as Progressive Jackpot slots, are renowned for their ability to award huge wins. These juicy jackpot games come with one slight disadvantage; players have to make the maximum wager to qualify.

This means greater investment is needed compared to playing traditional online slot machines.

So how do progressives work? Every time someone plays max bet on the game, part of their stake goes towards increasing an ever-growing prize called the progressive jackpot, which is made up of all other participating players’ bets over that period.

While progressive jackpots can reach millions of pounds, the chances of winning such a large sum are slim, similar to playing the lottery.

Below, we’ve listed the biggest jackpot slots with the best wins:

• Mega Moolah
• Mega Fortune
• Jackpot Giant
• Age of the Gods
• Aztec Millions

Branded Slots

Branded slots are official games that let you enjoy the best of modern entertainment. Slot providers are tapping into source materials from movies, TV series, and music – bringing us recognisable games with tons of fun graphics that reflect the most popular entertainment content.

With branded slot titles offering familiar settings like Marvel movies or Disney classics, these specialised games bring an extra spark to online gaming.

Branded video slots have the potential to be even more engaging and polished than your typical games. This is because they are produced with a bigger budget due to the financial support of popular brands backing them.

As such, you’ll enjoy cutting-edge technologies that create ultra-immersive worlds without ever leaving your home. Branded games need to be of superior quality, as they directly reflect the brand itself.

Examples of branded slots are Lord of the Rings, The Walking Dead, and Ellen’s Dance Party.

Video Slots

Video slots have taken the classic slot game and enhanced it with modern technology. They feature reels and colourful video screens, providing an immersive experience for players at all skill levels.

Today, video slot software developers have excelled in creating dynamic visuals and compelling soundtracks designed to draw gamers into each reel spin.

These games frequently include features such as paylines, side games, slot bonus rounds, excellent graphics, and even mini-games.

The RTP and variance of the games vary. Thunderstruck II, Starburst, Gladiator, and Gonzo’s Quest are some of the most popular online video slots.

Classic Slots

A classic slot machine is any game with mechanical reels or any online slot game designed to look like a mechanical slot machine. These games typically have simple paytables with no bonuses or extras. With their simple design and classic casino feel, these timeless games prove that sometimes less is more.

✅ Did you know? Some classics have the highest RTPs among online slots.

Some of the top classic slots at the UK online casinos are Vegas Wins, Flying Ace, Wild Diamond, and Seven & Fruits.

Yggdrasil Gaming is one of the iGaming industry’s rising stars, having been formed in 2013 and quickly establishing itself as an innovative force. Despite often flying under the radar compared to larger competitors, Yggdrasil produces outstanding high-quality titles such as Vikings Go Wild, Viking Berserk and Blood Moon Wilds, cementing its place among top developers in creating incredible slot experiences.

Mobile Slots

The modern-day trends are pretty clear: more and more people are turning to their mobile phones for entertainment. In response, the gaming industry has shifted its approach. Instead of designing games with desktops in mind and then adapting them later on mobiles, they now develop exclusively ‘mobile-first’.

This means that these awesome casino slot titles will fit perfectly on your phone, and you may even find some versions better than the desktop version, all from the convenience of your mobile phone.

Most slots are powered with HTML 5, which means no matter what screen size or resolution your device is, these games will automatically fit in for an uninterrupted gaming experience, whether during a routine commute to work or just a cheeky lunch break.

If you’re a fan of innovative features and latest trends, make sure to check out new slot sites. These platforms often offer brand new games, juicy bonuses, and fresh designs, so they are perfect for the early adopters.

With so many great mobile UK slot sites out there, you have your choice of gaming on the go! You can either access the slots through a simple web browser, visit the casino’s website, or your mobile Play store or App Store to download their specially designed apps.

And with tons of new and exciting online slot sites popping up all around Britain, it’s never been easier to get in on those bright lights and big wins, anytime & anywhere.

Main Features in Slot Games

Online slot machines are constantly evolving, with developers taking player experience to thrilling new levels. From Wilds and Scatters to Bonuses and Multipliers, the modern online slot landscape is full of potential. But what do these symbols actually mean?

Are they an advantage or a hindrance in your quest for big wins? Let’s uncover their secrets together because knowledge is key when spinning those reels.

Bonus Rounds

Bonus rounds bring the thrill of extra rewards and increased chances to win big. Accessible in many games, they offer an exciting opportunity to up your earnings as you play.

Exhilarating part of any game, bonus rounds can come in many forms, such as free spins, mini-games or even bonus wheels. These bonus symbols randomly pop up to give players great chances to score big wins.

Wilds

Wild symbols are used in slot machines to allow players to create a winning combination by substituting their wild symbol for any missing symbols. It’s easy to see how the inclusion of wild symbols in a game benefits players. Wild symbols in slots can be static or dynamic. They can also be used for other purposes. In more complicated video slots, for example, a wild symbol may trigger other events, such as expanding symbols or even bonus rounds, which could result in more winnings for you.

In some slots, wild symbols have no individual value, whereas, in others, they are the highest-paying symbols on the reels. However, you must keep in mind that you have no control over the appearance of these symbols. Wilds show up on the reels randomly, and whether or not they appear depends entirely on the players’ luck.

Scatter Symbols

If you’re a fan of playing online slots, then there’s one special feature that should be on your radar: scatter symbols. These bonus features are often bigger wins than wilds and usually have something to do with the theme or story of the game. Just remember not to expect too many, as these symbols aren’t as common, so it could take some time for them to pop up on the screen.

Wolf Gold slot’s scatter symbols: eagle, a horse, and a jaguar.

When three or more scatter symbols appear on the reels, they can trigger a round of free spins or, in some cases, an interactive bonus game with guaranteed cash prizes for the players.

How to Play Slot Tournaments

A slot tournament is a casino event in which players compete on slot machines for cash prizes. Slot tournaments may appear complicated, but they are actually quite simple. You pre-register for a casino’s slot tournament and will be assigned a slot machine number, a set amount of credits, and a time window to play. To be crowned the winner, you must compete against other casino players, and whoever has accumulated the highest winnings will walk away victorious.

Casinos typically charge an entry fee to participate in a slot tournament. This payment funds the tournament’s cash prizes, which can be huge.

The games frequently differ based on the number of spins that can be made within a specific timeframe or the highest percentage won by an individual player. They use percentages to allow players with varying bankrolls to enter while maintaining a level playing field. The prizes will also vary. Some of the larger tournaments may include cruises, 5* vacations, gadgets, cars, cutting-edge technology, bonuses, cash, and even free spins. They are commonly used to promote new casino games and generate some buzz around them.

What Bonuses Are Available at Slots Sites?

With an abundance of online casinos competing for your attention, bonus offers have become a vital part of the experience. A typical offer might include bonus money or free spins, giving you more bang for your buck and a better chance to hit it big.

Welcome Offers

The amount you can claim is determined by the online slot offer that you qualify for. This can vary depending on the wagering requirement, the amount of your first deposit, and the amount you deposit. It is important to note that casino bonuses are rarely just free money.

For example, a welcome bonus is bonus money that the casino gives out to new customers, but in order to withdraw the money, you must meet certain gameplay criteria. These are referred to as wagering requirements.

When you receive the incentive, you will be given the condition that you must wager through the bonus a certain number of times before you can withdraw winnings. This can range from 20x to 50x the bonus amount.

For example, for a welcome offer of £100, with a wagering requirement of 30x, you would need to wager £3000 (30 x £100) before you can cash out the bonus funds and winnings made.

Free Spins

Free spins bonuses are one of the most popular ways to attract new online casino players because they allow you to try out the casino, particularly the slots, and potentially win real money payouts to boost your bankroll. Free spins are exactly what they sound like: spins on a slot game that you can enjoy without risking any of your real money on the outcome. Most times, you can win money on these, but you can’t lose, which makes them an appealing offer to many gamblers, whether novice or professional.

The number of free spins you receive will be determined by the online casino you choose. It’s possible that the offer is only valid for specific games or game providers, so double-check to see how limited the offer is.

You may notice a wide range in the number of free spins offered by casinos, ranging from 10 to 200. These are frequently combined with additional incentives such as a “no deposit” bonus or a welcome bonus. There are also free spins on card registration UK offers available in several online casinos. All you need to do to receive it is add a valid debit card to your casino account during the sign up process, and the free spins are usually automatically awarded.

To ensure you’re getting the best bonus, don’t be swayed by the promise of 200 free spins if it comes with a long list of terms and conditions. Instead, consider which offer will work out the best overall, and you can relax knowing you’re getting a good deal while also having fun.

No Deposit Bonus

No deposit bonuses allow players to try out a new casino without putting any money at risk. As the name implies, no deposit or credit card information is required. The player only needs to sign up for an account and begin playing for free. Typically, the bonus is limited to a certain amount and is subject to certain restrictions. Most times, you will only be able to use it on slot machines. These restrictions may appear challenging, but casinos must impose them to prevent bonus hunters from simply cashing out their free credits at different casinos.

Deposit Bonus

Deposit bonuses are another popular way to entice new players to join online casinos. These bonuses, like welcome bonuses, will provide a multiple of the deposit after the player has opened an account. It could be twice, three times, four times, or even five times the amount deposited. Deposit bonuses of up to 100% can usually be used on table games like blackjack, whereas bonuses of 200% or more can only be used on slot machines.

Loyalty Bonus

Loyalty bonuses are a way for casinos to reward loyal customers through their loyalty programs. These bonuses are typically given to players after they reach certain milestones while playing their favourite casino games. These rewards can take many forms and are usually determined by the player’s actions. For example, if a player spends a lot of money in the casino or makes their 1000th bet, the sportsbook might decide to reward them with cash prizes.

How to Play Online Casino Slots

Slots are universally regarded as one of the easiest and beginner-friendly casino games. This means that the gameplay is easy to understand. However, if you want to be a pro at winning online slots, you’ll have to put in some work.

With some key strategies, there are several things you can do to improve your odds and have a good shot at winning the top prizes. Below are tips to help you start playing slot games for real money.

Slots RTP

When looking for a great slot title, there are some essential features to keep an eye on. From impressive bonus rounds and captivating themes to a highly desirable Return-to-Player (RTP) rate, the right selection could be your key to big wins. Have you ever been curious about how much money a slot machine can potentially payout?

Well, RTP may just hold that answer! In this digital age, developers must consider tech design and mathematical algorithms when creating their dream game – something both desirable and engaging for players. So let’s take a look at how these concepts come together with one key factor: RTP.

Assume you play a slot machine with a 96% RTP and wager a total of £100. Theoretically and statistically, this slot machine will return 96% of your total bet; in this case, £96. So, you won’t be at a loss if everything evolves as the theory suggests, but unfortunately, this is not the case.

The RTP cannot be achieved in a short session of hundreds or thousands of spins. RTP is the percentage of return to the player that is realised over time. Therefore, one session is meaningless because it takes countless spins for RTP to reveal its essence.

Slots With the Highest RTPs

Let’s take a closer look at some of the best RTP slots. These games aren’t necessarily the best choice if you’re looking for a big win, but they usually pay well and provide a good amount of playtime.

Devil’s Delight – 97.6%

Devil’s Delight is a captivating gaming experience packed with thrilling bonus features and an unbeatable 97.6% RTP, making it the perfect choice for players seeking to maximise their odds of winning. This game also offers visually stunning animations combined with its unique Soul-O-Meter feature, creating an unparalleled entertainment value sure to keep any player coming back time after time.

Mega Joker – 99%

This classic NetEnt 3-reel slot offers a unique fruit theme, and up to 80,000 coins can be won. But it doesn’t stop there; the return rate of your bet changes depending on how much you wager on each spin from as little as 10 coins. Plus, this game requires both luck and skill, as players need to know when it’s the best time to collect the winnings.

Jackpot 6000 – 98.8%

Jackpot 6000 from NetEnt is a classic slot for thrill-seekers. With maximum stakes of 10 coins, spinners can take the wheel with confidence and use the Supermeter strategy to maximise their returns. It’s an ideal pick for players who love to have control over results to some extent.

1429 Uncharted Seas – 98.6%

The 1429 Uncharted Seas slot by Thunderkick is one of the company’s older titles. While the graphics and features in this slot aren’t spectacular, the high RTP of 98.6% makes it worth a few spins.

Ugga Bugga – 99.07%

With this unique game, you’ll get the best of both worlds – slots and video poker. You can even increase your chances of success by taking advantage of the hold feature to match up different combinations across ten lines.

Blood Suckers – 98%

Enter the dark world of Blood Suckers and take on all vampires! With five eerie reels, 25 ominous paylines, wilds & scatters, you are in for an exciting adventure. Slay Vampires to earn your share of cash prizes as they come spilling out of their coffins. With 98% RTP getting a big payout won’t be too difficult either.

How to Pick the Best Online Slot

Depending on what you’re looking for in a slot, here are some pointers to help you pick the one that’ll provide you with some winnings.

Choose Slots With a High RTP

When choosing a title to wager on, an important factor to take into account is volatility in slots. A high RTP slot will mostly mean you will be playing a less volatile slot that will supply you with regular small wins. It is considered the safest approach. Slots with low RTPs may bring more huge wins, but it comes at the cost of a roller coaster experience for your bankroll.

However, if you’re comfortable taking risks and enjoy big dippers, it could lead to some huge rewards on these volatile slots.

Go For Low Volatility Slots

For the most enjoyable online slot experience, select games with low volatility and a high RTP. These titles are tailored to give more frequent wins. In addition, you’ll experience an even ride that awards small yet frequent payouts, meaning your credits should stay afloat much longer. Choosing the best online slot game based on variance entails determining what you want from the gameplay.

Find a low volatility game if you would love to play for a long time on a small bankroll. However, if you want more chances at jackpot-style payouts, you should play high volatility online slots.

Play Slots From Top Developers

With the right platform, your gaming experience can be enhanced exponentially. To get a thrilling slot adventure and ensure you are playing games of top quality, it’s always best to seek out those powered by leading game developers like Playtech, NetEnt, or Microgaming. Established gaming studios have a wealth of experience and knowledge under their belts, with years of trust earned behind them.

From reliable gameplay to secure online environments, these highly reputable companies offer peace of mind when it comes to safe & responsible gaming, giving you the freedom to play without worry. Of course, new developers are coming through each day offering fresh titles, but for added security, sticking with well-known names is an easy way to stay protected.

Don’t Fall for Myths Around Online Slots

Lastly, stick to the proven and reliable information on online slots. There are a lot of myths circulating around the web that aren’t true. For example, there are a lot of misconceptions around the best time to play online slots, and whether there is any at all. So, equip yourself with trustworthy information for the best outcome and a safe gaming experience.

Remember to Gamble Safely and Responsibly

Gambling should be a form of entertainment at all times. While online casinos offer a lot of excitement and entertainment, it’s important to gamble within your means and never bet more than you can afford to lose. It’s also important to recognise the signs of problem gambling and seek help if necessary.

Excessive gambling can lead to financial difficulties, addiction, and other negative consequences so it is important to be aware of the risks involved and the responsible gambling practices on the other hand.

A few guidelines to follow are:

• Set monetary and time-bound limits
• Gamble only the amounts you can afford to lose
• Never chase your losses
• Don’t gamble when upset, angry, sad, depressed, or intoxicated

🚫 Please note that in the UK, only individuals aged 18 and over are legally permitted to engage in gambling activities.

For help with a gambling problem, call the National Gambling Helpline on 0808 8020 133 or go to www.gamstop.co.uk to be excluded from all UK-regulated gambling websites.

Manage Your Bankroll Carefully

When engaging in online gambling, set and adhere to a specific budget for how much money you can afford to lose without affecting your daily life. Establish limits on the amount you wager in each session, decide on the duration of your gambling sessions, and resist the temptation to chase losses by spending more than you’ve allocated.

Another way to effectively manage your bankroll is to adjust your bet sizes based on your total bankroll to extend your playtime and reduce the possibility of depleting your funds too quickly. Responsible bankroll management helps maintain gambling as a form of entertainment, ensuring that it does not lead to problematic gambling behavior or financial distress.
