Best Online Slots Sites in the UK

1. Simba Slots

Expert Ranking – 4.9/5

As a well-known online slots site across the UK, Simba Slots has an excellent selection of game types to suit all players, new or experienced. Some of the high-quality and rewarding games on offer at Simba Slots include slots, jackpots, live casinos, casinos, and instant win games, depending on a player’s preference. Simba Slots’ live dealer section is top-tier; it has every variation you could want, including Blackjack, Roulette and Poker and occasionally offers promotions for these games. Simba Slots are certainly not shy about promotions and offer bonuses like welcome offers and no deposit bonuses. The current generous welcome offer at the site is 5 free spins no deposit! 

What Could Be Improved: 

Simba Slots’ users would want to see more live dealer games available. Users who enjoy live casino games were dissatisfied, even though the games that are now offered are of the highest calibre and entertaining. The fact that Simba Slots offers a number of promos with stringent wagering restrictions is another thing our specialists noted, and they would want to see more deals without limitations.

2. Slots Animal 

Expert Ranking – 4.9/5

Slots Animal offers an extensive selection of slot and casino games. In the large slot game catalogue, customers can find original, new and feature slots. As well as this, they can also find many slots which have been developed by Slots Animal specifically for its site; these slots cannot be played anywhere else. New players can look forward to potentially earning some top prizes through the Slots Animal welcome bonus, where newly registered players receive 5 free spins without having to make a deposit, however if you join and deposit £10 you can spin the Mega Reel and win up to 500 free spins on Starburst! 

What Could Be Improved: 

As previously said, Slots Animal is a fantastic slots website, but like many websites, it could use some work. For instance, we would want to see a lot fewer large marketing banners and advertisements on the website. Slots Animal also has a number of territory and country limitations which left some users disappointed.

3. Aladdin Slots

Expert Ranking – 4.8/5

On the casino scene since 2018, Aladdin Slots is one of the best online slot sites that has built a brilliant reputation amongst bettors. A considerable advantage of the Aladdin Slots site is its top-tier VIP program. To increase level progress, players must complete fun tasks to unlock trophies. Each trophy unlocked will increase your progress. Each level you go up will provide you with a free spin on the Mega Reel; the higher the level, the better the Mega Reel prizes. A unique feature of Aladdin Slots is its fun and exciting theme with top-notch graphics, features, colours and promotions. The promotions are both rewarding and simple to claim. New users at Aladdin Slots can partake in the generous welcome offer where players can receive 10 free spins no deposit and up to 500 free spins as part of a deposit bonus. 

What Could Be Improved: 

Like many online casinos, Aladdin Slots is not perfect and might be improved. When possible, this can be achieved, for instance, by lowering or doing away with the charges associated with withdrawal transactions. It would be better to avoid these expenditures even if they are not excessive. On top of this, Aladdin Slots could do with some more customer support options.

4. Immortal Wins Casino

Expert Ranking – 4.8/5

At Immortal Wins Casino, customers can find a huge list of promotions, including an extremely generous welcome offer where new customers can receive 5 bonus spins for the Immortal Romance slot; no deposit is required. On top of this, players can also access scratchcards, cash drops, slots, bingo, live casino, prizes, daily and VIP offers. Some examples include its Happy Hours offer, which takes place between 3-7 pm every Wednesday, and the Turbo Reel, which can be spun on every qualifying deposit. Here you can find hundreds of slot games, including both fixed and progressive jackpots. With full licensing from the UK Gambling Commission, players can rest assured that they will receive a high-quality gaming experience.

What Could Be Improved: 

The one major disadvantage we found with Immortal Wins Casino is that it can’t be played anywhere a player wants because it’s only legal in a few countries. The United States of America, Belgium, Italy, France, Bulgaria, Russia, and Turkey are among the countries and areas that are forbidden.

5. Pokerstars Casino

Expert Ranking – 4.7/5

As one of the best online slot sites available, slots aren’t the only game this casino excels at; Pokerstars has also emerged as a top site for casino games and sports markets with some of the best payout levels in the UK. Pokerstars entices various players due to their brilliant range of games and rewarding bonuses. New users can enjoy the welcome bonus, which is a 100% deposit bonus of up to £200. Customers at Pokerstars Casino have a variety of banking alternatives to select from, including Skrill, Neosurf, Apple and Google Pay, Trustly, and Direct Bank Transfer. Players who prefer to play on the go are in luck as the site offers a mobile-optimised mobile slots site and app. 

What Could Be Improved: 

Regretfully, because of the different national limitations the website imposes, players are unable to play PokerStars Casino anywhere they like. Many users would want the site to be more accessible anywhere possible. Also, as many people have pointed out, there are a lot of subpar Bespoke games available.

6. William Hill Vegas

Expert Ranking – 4.7/5

At William Hill Vegas, players can access a vast range of promotions for all kinds of casino games, whether that’s slots, bingo or interactive games live casino. These casino bonuses include free spins, prizes, multipliers, free bingo rooms and more. At William Hill Vegas, a variety of Slingo games are also on offer if that is something that tickles your fancy. All the popular slots you love can be found at William Hill Vegas; this includes Starburst, Book of Ra, Fishin Frenzy and Gates of Olympus. With licensing from the UK and Gibraltar, users can rest assured that they will receive a secure gaming experience. New customers at the site can participate in the brilliant free spins slots bonus currently available, requiring users to stake £10 to receive 100 free spins. 

What Could Be Improved: 

When it comes to the selection of promos, William Hill is not as good as other websites, and even the bonuses that are offered have rather high wagering requirements. Numerous consumers, including our specialists, would prefer to see advancements in this field.

7. Betfair Casino

Expert Ranking – 4.7/5

Established back in 2000, Betfair has had several years of experience in the casino world, making them a trustworthy site. One thing in particular about Betfair Casino that stands out to us is the long list of reliable deposit and withdrawal methods bettors can pick from, including Neteller, Apple Pay, Bank Transfer, Paysafecard and MuchBetter. Betfair users can play hundreds of games, such as slots, jackpots and live dealer games, all from the top software providers ensuring a high-quality gaming experience. Betfair offers new and existing customers a range of generous bonuses, including welcome and no-deposit bonuses. The current new customer offer at the site is 50 free spins upon registration. 

What Could Be Improved: 

Betfair Casino provides a wide selection of bonuses and promotions, but many users have found that some of them have wagering requirements that are high, which is not ideal. In order to add some variation to their betting experience, most players would prefer to see promotions with reduced or no wagering requirements.

8. Betfred Casino

Expert Ranking – 4.7/5

A great feature players can find at Betfred Casino is its game of the week page, where bettors can find Betfred’s top game and why Betfred have chosen it, this can be due to the RTP; promotions relating to the game, comp points or other reasons. At the time of writing this, Pyramid Linx is the game of the week due to the ability to earn comp points while playing. Betfred loves to reward players through generous bonuses and promotions, so why not also check out its great VIP program? New customers at Betfred Casino can enjoy the current free spins welcome offer, which is stake £10 and get 150 free spins! It’s as simple as that. Sign up for the Betfred slot site today.

What Could Be Improved: 

Despite the many payment choices that Betfred Casino provides, our specialists have noticed that withdrawal times may be very long. It’s unclear if the payment methods themselves or Betfred’s processing time is to blame for this. We would want to see faster withdrawal times in any scenario, either by offering more payment choices or by processing requests more quickly.

9. bet365 Casino

Expert Ranking – 4.7/5

As one of the most recognised names in gambling, bet365 Casino is certainly a site that bettors can trust. bet365 offers a variety of the top slot games for players to pick from. Every game available at bet365 Casino comes from top gaming software providers, including the likes of Microgaming, Pragmatic Play and IGT. You can even find a top-notch sportsbook at bet365. By providing a safer gaming environment where users may establish deposit limits, reality check, exclude themselves, and time out, the bet365 team uphold a high standard for guaranteeing that customers gamble responsibly and safely. The site is highly rated for its range of brilliant customer promotions. Users can enjoy the current deposit £10 and get 50 free spins welcome bonus. 

What Could Be Improved: 

While bet365 Casino offers one of the biggest welcome bonuses we’ve seen, the current customer specials are a little lacking. The bonuses aren’t bad, but there isn’t enough variation, therefore we think that should be changed.

10. All British Casino

Expert Ranking – 4.6/5

Known as one of the best payout casinos in the industry, All British Casino is a fantastic site. The major casino game software developers, such as Evolution Gaming, Blueprint Gaming, Novomatic, Pragmatic Play, and IGT, are the source of the All British Casino games. Users will also discover a thorough and useful Frequently Asked Questions area at All British Casino for any pressing queries or worries. All British Casino’s fun theme makes the site fun and exciting for players to explore, where they can find a variety of slot and themed games which cater to all kinds of players’ interests. The site offers a variety of generous promotions, including the welcome bonus, which is a 100% deposit bonus of up to £100. 

What Could Be Improved: 

About enhancements, we had two observations about All British Casino. First off, a lot of live casino enthusiasts were disappointed because there were no live poker games available. The other is that All British Casino doesn’t have as many payment alternatives as other websites.

Branded Slot Games

Branded slot games are those that relate to brands, whether that is a movie, TV show, band, musician, musical, sport, game or anything else related to pop culture. These games are extremely popular amongst players as they cater to user interests and are generally extremely high quality due to a higher budget than most slot games. All of these games tend to have special bonus slots features that relate to the topic they’re based on. Branded slot games can be found at most slot sites. Some top examples of this slot variant include The Dark Knight, The Simpsons and Jumanji.

Video Slot Games

Players can find other special features attached to video slots, including pay lines, mini-games and excellent graphics.

Jackpot Slot Games

Jackpot slot games online are one of the most popular slot variants due to the huge cash prizes that are up for grabs. There are two kinds of jackpot slots, fixed and progressive. On fixed slots, the jackpot stays the same, whereas, with progressive jackpots, the prize pool increases with every deposit that is made on the game, so the jackpots on progressive games are huge. Jackpot slot games can be found at many slot sites, so be sure to keep an eye out for them. Some of the best jackpot slots at the top online slot sites include Megah Moolah, Millionaire Genie and Gladiator. 

Classic Slot Games

Classic slot games are not technically slot game variants as they are based on the original slot games, they imitate the appearance of mechanical slots, and they usually take the format of 3 or 5-reel games. More often than not, classic slot games have the classic fruit machine theme. This game type can be played at any casino or sports book, offering slot games. Classic slots are suited to players who enjoy the original game’s simplicity without adding modern features. Some top classic slots to look out for include Red Hot Wild and Break Da Bank.

Guide to Best UK Online Slots

• Online Slots Licensing and Security

Under UK law, to operate a gambling site in the United Kingdom, it must receive licensing from the UKGC, also known as the UK Gambling Commission. This governing body regulates the site and ensures that it offers players a safe, secure and fair site, meaning that it uses data encryption technology to protect personal information. These UK slot sites are also required only promote games that use random generators so that chances of winning are fair and even for all players. 

• RTP Percentage

The RTP (Return To Player) percentage comes attached to every slot game you will play. It means that over a certain period of time, a player should receive a percentage of what they’ve wagered back in winnings. This varies from game to game. An example of how the RTP works is as follows; if you wagered £100 on a slot game with a 96% (average) RTP, you would receive around £96 in winnings over time. Another aspect to look out for is volatility; this relates to winnings; a site with high volatility rewards bigger winnings over a shorter period, and a low volatility rewards small winnings over a long period.

• Slots Bonuses

There is a selection of slot bonuses obtainable while playing slots or playing at a slot/casino site. Some of these are in-play bonuses; these are unlocked by matching certain symbols on the reel, and they can unlock free spins, multipliers and more. Other slot bonuses that can be claimed are welcome, no deposit, deposit match, VIP, refer-a-friend and birthday bonuses, among others. Rewards include free spins, multipliers and deposit bonuses. Slot bonuses are extremely popular as they can potentially reward players with substantial prizes.
