Picking Slots to Play Online
Once you have made your choice of the best UK slot sites and picked out a bonus, it’s time to start playing! On each online slot site, you can find hundreds, if not thousands, of slot games. If you are new to slot games, here are a few tips to help you start exploring:
- Start with the Free Spins Slots:
No need to make it harder than that! You can test several different slots just by claiming a few of the free spins bonuses we list on this page. - Test Different Themes:
There is a slot about anything and everything. Animals, movies, the Irish, the Ancients, and space are all deeply explored themes you can find at any slots site. - Figure Out Bonus Features:
Fruit slots are super classic, Vegas-y games without many frills. Megaways slots have thousands of ways to win and all sorts of bonus features. You can also find anything in between, so testing different slots to see what type of (if any) extras you like the most is very useful. - Check RTP:
The higher the RTP, the more money the slot hands back to players over time. It’s not a guarantee you will win, but your odds are a bit better with high RTP games. Most slot sites provide this info in title cards. - Volatility:
Volatility represents how often and how much a slot pays out. Low volatility slots pay smaller, frequent wins, while high volatility slots pay larger but less frequent wins. Which one you prefer is up to you, but you might get to play longer with low volatility games.

Popular Software Providers for Slots
The best slot sites have a mix of casino games from many online casino game providers. Many of them have a signature look or series that keeps players engaged with their games. Below we’ve gathered the top providers who make our favourite slot games.
- NetEnt:
Established in 1996 in Sweden, NetEnt has given us some of the best slots ever, including Starburst, Gonzo’s Quest, and Finn and the Swirly Spin. NetEnt casinos also have many slots tied in to popular TV & movie franchises, including Narcos, Knight Rider, and Gordon Ramsey’s Hell’s Kitchen. - Microgaming:
Microgaming is one of the biggest slot developers in the world. They have so many games to choose from that there are some Microgaming casinos, which don’t see the need to sign up with any other game providers. They have made slot versions of fan favourite shows, such as Game of Thrones, Battlestar Galactica and Jurassic Park. - Playtech:
Playtech is probably best known for their Age of the Gods slots. They draw on Greek mythology and multiple bonus features to create a lasting legacy. Many variants exist, but our favourites are Age of the Gods – Goddess of Wisdom and the recent foray into the Nordic legends, Age of the Gods Norse – Gods and Giants. You will normally find several titles at the best Playtech casinos. - Play’n GO:
The most famous Play’n GO game is the monumental success Book of Dead. Players just can’t get enough of the slot’s protagonist, Rich Wilde, who has taken on a life of his own and spawned many sequels. What really makes Play’n Go casino games stand out are the exciting stories that unfold as you play. The slots have lots of bonus rounds and features, lacking in many competitors’ lacklustre copies of these games. - IGT:
IGT makes both online slots and real-world live casino slots that you can find all over the world in brick-and-mortar casinos. They have created a range of branded video slots, including Transformers, Harley Davidson and Ghostbusters. They also have the most cat-themed online slots of any game provider, such as Kitty Glitter and Prowling Panther. - Yggdrasil Gaming:
Although you won’t find Yggdrasil Gaming’s slots in as many casinos as the bigger studios, it is well worth hunting them down. Yggdrasil is committed to creating a high-quality gaming experience for slot players, and its graphics are second to none. Check out Vikings Go Berserk and Blood Moon Wilds in particular. - Red Tiger:
Red Tiger slots are some of the most sought-after games due to their epic progressive jackpots and Daily Drops. The games are also chockablock with surprises and bonus features! Their most popular games include Piggy Riches Megaways, Narcos Mexico, and Primate King. One of our favourites is the highly volatile Reptizillion Power Reels. - Red7 Slots:
Bristol-based studio Red7 Mobile were renowned for making slots that worked perfectly on hand-held devices since the dawn of smartphones in the 2010s. They were acquired by gambling industry giant Scientific Games in 2017. You can still find a number of Red7 Slots at some of the biggest UK slot sites, just under a different brand name. - No Limit City:
No Limit City is an independent Swedish studio pushing the boundaries of what slot games can be. You will not find any cute leprechauns or relaxing fishing games in the catalogue, but rather angry roadkill or graffiti-covered public toilets. This studio is the Marmite of the online gaming world – you will either love them or hate them.
Online Slots Tournaments
Slot tournaments are one of the main promotions online slot sites provide to existing customers. Usually, the site marks certain slot games as part of the tournament. Players can participate by playing these games with a certain amount of money.
If you want to take part in slot tournaments, make sure to check the casino websites for information on them. For example, when they start, what you need to do to participate, and how often you can play in order to win are key details to know.
There are a couple of different types of slot tournaments. One Hit awards the highest single win over a specified number of spins, while Fair Change divides the wins by stake, giving everyone the same chance to win.
Here are the top slots sites offering daily tournaments:
- Voodoo Dreams: There’s a tournament every minute of the day. You earn access by participating in Duels, where you play against another player.
- Videoslots Casino: The Battle of Slots allows you to interact with other players and choose from several tournaments, which start up frequently.
- Coral Casino: They provide both free and real money tournaments weekly.
- Magical Vegas: New tournaments launch after the previous one ends; a lot of them don’t require huge bets to participate.
How to Stretch Your Bankroll with Online Slots
Even if you’ve picked the best slot sites, winning is ultimately based on luck. With that said, there are a few ways to make your spins go further:
- Take Advantage of Bonuses: No wagering spins offer the best chance of walking away with some winnings.
- Choose High RTP Slots: Return to Player (RTP) is the percentage of wagered money a slot returns to players over time. High RTP slots like Blood Suckers (98%) and Mega Joker (99%) offer the best chance of winning.
- Play Slots with Low to Medium Volatility: Medium volatility slots offer a balance between frequent payouts and bigger wins, but are harder to find than low volatility ones.
- Set a Budget: Slots are random and every spin is independent, so don’t chase wins by betting more every spin. Use responsible gambling tools like deposit limits and reality checks to stay on top of your spending.
- Bet Strategically: Small, steady bets can stretch your bankroll more than going all in on a few spins. You can win big without using the max bets!
- Try Demo Mode: We have hundreds of demo slots you can play without risk. Testing different slots helps you understand bonus rounds, paylines, and features before wagering.
How We Rate UK Slot Sites
In addition to having a ton of the best slot games, the best UK online slots sites excel in many areas. We rate online casino sites based on eight different factors listed in our Editorial Policy. Below are the most important categories for top slots sites:
Licensing
First and foremost, we only recommend and list slot sites licensed and regulated by the UK Gambling Commission. These sites follow all regulations to take care of their customers’ funds and personal details, in addition to running fair games.
The regulations have strict standards for player protection, fairness, and financial security. You can find the UKGC stamps on each website to indicate they have passed the inspection and received a license. If you only play on slots sites recommended by BonusFinder, you can be sure that they are legal.
Slot Library
When recommending online casinos for specific games, we naturally take a look at their casino games and the variety they offer. When it comes to the best slot sites in the UK, we are very fortunate since most operators have such a wide selection of games to choose from.
The best sites also run slot tournaments and other promotions that slot players can take part in to enhance their gaming experience.
Bonuses
Naturally, welcome bonuses are an important factor when choosing among online slots sites. There are a ton of bonus spins and deposit offers to choose from, so it might be difficult to pick the best offer for you.
For example, each casino bonus on BonusFinder has been tested to make sure there’s no “catch” that makes it impossible to wager. You can always trust that we have your best interests at heart.
The best online slot sites listed here have great bonuses you can use on slot games. We consider factors like initial deposit and wagering requirements when looking for offers.
Payment Options
We seek out the best slot sites with convenient payment options like eWallets and pay by phone. Depositing funds is simple on all sites, and you can always withdraw your deposits whenever you feel like it.

UK Slots Regulations & Responsible Gambling
Online slots are regulated a bit more in the UK than in other countries. The purpose is to keep players safe and gaming fun. These regulations are implemented on every slot site, so you can’t avoid running into them when you play.
The UK Gambling Commission has banned a couple of features on slot games: bonus buys and auto spins. Bonus buy lets you skip the base game and buy your way to the bonus game, which might encourage reckless spending. Auto spinning means you don’t control the spins yourself, but instead set the reels to spin automatically up to 100 times.
In addition, the UKGC requires 2.5 seconds between spins to promote safer gambling. In Spring 2025, the UKGC also set age limits to bets: 18 to 24 year olds can stake a max of £2, while 25+ can stake a max of £5.
Finally, credit cards are not allowed as deposit methods at any online casinos in the UK.

FAQ
- What is the best slot site to win real money?
-
Because the games at licensed slots sites are random, you are not more likely to win at one site than another. However, some sites are considered "best paying" because they have more high RTP slots than others. Our best paying pick is All British Casino.
- Can I play real money slots on my phone?
-
Absolutely. In 2025, all slots sites should work perfectly on your phone, and most are designed on a mobile-first principle. All the bonuses we list can be claimed by both mobile and desktop players, and some casinos provide casino apps for added convenience.
- Are online slots rigged?
-
Although some players express concern that online slots are scams and never pay out, this is absolutely not the case. To get a licence from the UK Gambling Commission, the sites have to prove that their casino games and slots are fair. For example, the Random Number Generators that control them must be tested and found truly unbiased. All sites recommended by BonusFinder are fully legal in the UK, so you can be confident that you are not being conned.
