Best UK Slot Sites by Category

To help you find the UK online slot site that best suits your needs, we’ve outlined how we rank our top picks across the categories below:

Best Progressive Slots Sites

When searching for progressive slot sites, we look for operators that have progressive slots from a number of providers, jackpot levels ranging from millions to smaller payouts, and collections that offer lots of jackpot slots.

1. QuinnCasino

With 70+ jackpot slots, QuinnCasino offers progressives from major studios, including Games Global and NetEnt. The neatly organised game lobby displays slots in large thumbnails, while each card shows the current jackpot amount. Notable progressive jackpot slots include the WowPot and Mega Moolah slots series from Games Global and the Power Play Jackpot series from Playtech.

Top 3 Reasons to Visit

  • 70+ jackpot slots

Plus, Winomania offers scratch cards with progressive jackpots. Top jackpot games include Mega Moolah, Mega Fortune, Wheel of Luck, and Mr & Mrs Scratch.

Top 3 Reasons to Visit

  • A good range of different jackpot slots

Best Megaways Slots Sites

Megaways is a popular slot mechanic created by Big Time Gaming that randomly modifies the reels of the game to increase the number of paylines for each spin. Standard Megaways can expand to 117,649 ways to win, but some variants may have more. Top Megaways casinos will have a deep collection of slots with this mechanic and make it easy to find them with a dedicated section.

1. Luckster

Luckster’s Megaways collection flies under the radar because there is no dedicated section for these games. However, if you put Megaways into the search bar, you will find 150 options to choose from. This fantastic lineup of Megaways slots includes popular titles like Bison Rising Megaways, Fishin Frenzy Megaways, and Eye of Horus Megaways.

Top 3 Reasons to Visit

  • 150 total Megaways slots
  • Progressive jackpot Megaways
  • Choose between around 2,500 total slots

2. Winomania

Winomania does have its own section for Megaways slots, making it much easier to locate these games. There are around 50 total Megaways titles at Winomania Casino. This impressive collection includes some iconic Megaways, including the first-ever game Bonanza. Other popular games include Mustang Gold Megaways and Rainbow Jackpots Megaways.

Top 3 Reasons to Visit

  • 150 Megaways slots
  • Slots from over 100 software providers
  • 3 deposit welcome bonus with Free Spins

Best Slot Sites for High RTP Slots

RTP (Return to Player) is a metric that shows the percentage of money that a casino game pays back to players on average over time. It’s important that UK slot sites have a selection of high RTP games, as players like slots that have a higher-than-average RTP. The average RTP for online slot machines is 96%.

Barz Casino

With over 4,900 total games and over 4,500 slots, Barz has loads of flexibility when it comes to online slot machines. The casino boasts one of the biggest game libraries out of any operator on our top 10 online slots sites list, meaning UK players have plenty of high RTP slots to choose from. You can scour through Barz Casino’s game categories or use the handy search tool to find slots that are famous for their high RTP, including the following options:

  • Book of 99 – RTP: 99%
  • Mega Joker – RTP: 99%
  • Crazy Free Fruits – RTP: 98%
  • Money Cart – RTP: 98%
  • Blood Suckers – RTP: 98%

Best Slot Sites for Free Spins Bonuses

Many casino sites now offer Free Spins bonuses, but a great bonus should be both generous and easy to claim. A top Free Spins promotion gives you plenty of spins while keeping the terms and conditions fair, including low or no wagering requirements. Below are the best Free Spins bonuses available at our top 10 UK slots sites:

Slot SiteBonusWagering (Y/N)Bonus Code
QuinnCasino50 Free SpinsNFREESPINS
Winomania100% up to £100 + 100 Free SpinsWINO100
LiveScoreBetBet £5, Get 5 Free SpinsNN/A
Luckster100% up to £200 + 100 Free SpinsYN/A
LottoLand100, 150, or 200 Free SpinsNN/A

Best Slot Site for Game Variety

Game variety can be a tricky metric. On the one hand, a site with thousands of games obviously has a lot of options. However, simply having loads of games doesn’t mean automatic flexibility. Some smaller game portfolios may have more types of slots, such as Megaways, progressive jackpots, video slots, old-school slots, high RTP games, and so on. Top UK online slots casinos can combine a large collection of games with excellent variety.

Barz Casino

Barz is a great example of a casino that has loads of slots to pick from alongside a flexible catalogue of different slots. You can find a massive selection of standard video slots from over 100 software providers, meaning you get all types of genres and game mechanics. Sections are split to include dozens of jackpot slots and over 100 Megaways titles.

Best Sites for Slot Tournaments

Tournaments are interesting because they are the only way to play slots against other people. When looking for the best slot sites with exciting tournaments, we rate those with favourable payout structures with the biggest prizes. We also like to see popular games included in tournaments, including titles from leading developers like NetEnt, Pragmatic Play, IGT, and Games Global.

Below are the slot sites with the best tournament play:

  • Fafabet: At Fafabet Casino, you’ll find regular exciting slot tournaments, including the iconic Drops and Wins tournament from Pragmatic Play. You can even filter games to find selected tournament titles.
  • Luckster: You’ll also find the famed Pragmatic Play Drops and Wins tournament at Luckster Casino, with up to £2,000,000 in prizes up for grabs every month.
  • Pub Casino: This popular UK online casino is known for hosting regular monthly tournaments. Most recently, Pub Casino featured a Wild West Tournament with a £2,500 prize pool.

Choosing The Best Slot Sites

With so many options available, finding a place to play slots in the UK is easy. The real challenge is finding a UK slots site that offers the best all-around experience. That’s where we come in. As you compare different brands, consider the following criteria to help you choose the perfect site for you:

1. Free Spins and Bonuses

Any casino site should offer bonuses. However, all bonuses are not created equal, and you’ll need to dig into the T&Cs. Important terms to consider are wagering requirements, time limits, minimum deposits/bets, and game restrictions. Top casinos are good at offering benefits such as free spins while making their promo accessible to most players. A good example is Winomania, where you can claim a 100% deposit match up to £100 and get 100 Free Spins.

2. Range of Providers

There are hundreds of slot providers out there, giving you plenty of flexibility when playing online. Even so, some providers stand out as industry leaders because of the quality of their games and prolific output. Our recommendation is to choose a casino with a healthy selection of slots from these major studios. At the same time, pick a site that also caters to more niche games from smaller developers.

  1. Games Global – Immortal Romance
  2. NetEnt – Starburst
  3. Play’n GO – Book of Dead
  4. Pragmatic Play – Gates of Olympus
  5. Playtech – Age of the Gods
  6. IGT – Cleopatra
  7. Relax Gaming – Temple Tumble
  8. Thunderkick – Pink Elephants
  9. iSoftBet – Aztec Gold Megaways
  10. Yggdrasil – Valley of the Gods

3. Game Variety

Quality over quantity is the golden rule, so always pick a casino with flexible gaming over one that offers loads of the same game type. Leading casinos are good at curating game catalogues that cater to different players across desktop and slot apps. For example, video slots, classic slots, jackpot slots, Megaways, and new releases, alongside casino favourites such as blackjack, roulette, and poker. Barz is an example of an online casino that expertly combines lots of games with great options.

4. Payments and Payouts

The best slot sites give UK players plenty of popular and secure payment methods to choose from, including debit cards, e-wallets, and prepaid options. Many players value casinos that allow fast transactions, and the best sites process withdrawals within 24 hours. However, it’s important to note that different payment methods have varying withdrawal times, with e-wallets offering the quickest cashouts of around 48 hours.

fl sanitize

5. Licensing and Regulations

This is one area where you should be firm and make no compromises. Always choose a casino site that holds a licence from the UK Gambling Commission. This ensures the site meets UK regulations for player safety, fair gaming, and data protection. A great starting point is our list of slot sites, as we only recommend platforms with a valid UKGC licence.

New Slot Sites in The UK

New Online slots sites launch on the UK market each year, and we’ll be ready and waiting with our impartial reviews to help you decide whether to join or not. Here are some important things to consider when selecting a new slots site:

  • New casinos don’t have the time to establish themselves. Unfortunately, some new sites may cut corners in terms of licensing and security. Remember, only pick a casino site that has a licence from the UKGC.
  • On the flip side, you can often find generous promotions on newer sites, as bonuses are a good way to attract players.
  • Similarly, new casinos appeal to players by offering larger game libraries and will often partner with more software providers.

Summary of Slots Bonuses

UK online slot casinos use bonuses to attract new players and keep returning users loyal. That doesn’t mean all bonuses are as they seem. It’s important to always read the terms and conditions to ensure you are getting a good deal. Let’s be clear: a bonus is a reward for players, but casinos give nothing away for free. Always carefully consider the overall bonus you receive and how easy it is to claim.
When you browse the top UK slot sites we list on this page, you will find a bunch of generous promos, including the following options:

  • Welcome bonus: A bonus for new players, which is usually a deposit match combined with Free Spins.
  • Deposit bonus:This is any casino promotion that requires you to make a deposit.
  • Free Spins: A bonus where the casino gives you free spins on a popular slot game or series of games.
  • No deposit bonus: Some rewards, including Free Spins, can be available without you needing to deposit your money.
  • Deposit match:This is a common bonus where the casino matches your deposit. For example, 100% up to £300 means if you deposit £100, you get £100 in bonus money.

Being Safe with Slot Bonuses

We have spoken about terms and conditions and how important they are to bonuses, but below are the most important T&Cs to check for:

  • Minimum deposit: How much you must deposit to become eligible.
  • Wagering requirement: A number showing how many times you bet through a bonus amount before cashing out your winnings.
  • Time limits: How long you have to claim the bonus and meet the wagering requirements.
  • Payment restrictions: Some bonuses don’t accept payments from certain platforms, such as Skrill or Neteller.

How We Rate UK Slot Sites

With over 100 casino reviews under our belt, we know exactly what to look for when rating UK casino sites. Our team combines decades of experience through a strict multi-step process. We live through the casino experience to give a complete overview of what you can expect. Below is a closer look at our process:

1. Initial Research

Each review takes a month and starts with deep research into the brand.

  • We read reviews from fellow players, such as on Trustpilot. Our team also checks the reputation of the casino operators.
  • At least two of our review team are on the slot site to conduct first-stage checks.
  • We never compromise on safety, so we check licensing and security.
  • If a casino doesn’t have a UKGC licence, you will not see it on our list.

2. Registration, Deposits, and Bonuses

Kicking the review into gear, at least one member of our content team and another from our commercial team will register with the site. We will also discuss verification steps during registration or before you can withdraw.
As real money players ourselves, our review team always deposits money into the casino. We report on which payment methods are available, deposit times, and more. Because we claim the bonus, we can say exactly what terms and conditions are in place and how accessible the promo is.

3. Gameplay and Withdrawals

We spend a month with an online slots site review, where we cover the total games available, categories, software providers, top games, and the overall RTP.

We play enough games during a review that we always win and want to cash out. Our reviews show which withdrawal methods are available, if there are any fees, and what the limits are.
We will also explain how long it takes to cash out winnings, including verification times and processing time.

4. Updates

We recommend bookmarking our reviews because the process is never complete. If a casino we review makes an update, we will edit our review to reflect the change.
Our industry experts are constantly on the lookout for new updates, features, game releases, bonuses, and more, which we add to our reviews and rankings.

What are Slot Tournaments?

Slot tournaments are competitions for online slots on UK casino sites and are the only way to compete against other slots players. A casino sets a time limit for a tournament and a prize pool and players access by buying in or entering for free. During the tournament, players gain points by having winning spins on specific slot games. At the end of the tournament, the casino pays out to players with the highest score.

Finding the Best Slot Tournament For You

There are many types of slot tournaments, and which you choose will depend on your specific requirements and/or budget. To help you pick the best tournament for you, below are the most common types available:

Sit ‘n’ Go tournaments

Pay to enter and sit until the tournament fills with players.

Buy-in tournaments

You pay to enter the tournament and receive a set number of chips/credits to play with.

Reloader tournaments

If you run out of credits during the tournament, you can buy in again to receive more.

Survivor tournaments

A classic round-robin style competition where you play through rounds and knock out opponents as you progress.

One-shot tournaments

A common tournament type where you have no opportunity to buy in again.

Freeroll tournaments

Enter a tournament for free without paying entry. Freerolls usually have smaller overall prizes.

Types of Online Slots

Slot games come in many different styles and genres. While there are similarities and crossovers for all types of slots, there are differences you should consider before you play:

  • Free Slots: Any slot game that you can play for free. Most online casinos allow you to play slots for free in demo mode without risking your own money. However, you will not be able to win real money or claim bonuses. Even so, free play is ideal if you want to test a new game before you risk your money.
  • Real Money Slots: A real money slot is any slot game that allows you to risk your own money to play. All games you find on UK slots sites are real money games.
  • Classic Slots: If you see an online slot that looks and plays like an old-school fruit machine, this is known as a classic slot. There are clear gameplay differences as classic slots have one payline, just 3 reels, and don’t have features such as respins, wilds, and free spins.
  • Multi-Reel Slots Vegas Slots: As the name implies, this type of slot features multiple reels and is inspired by slot machines you’ll find in the gambling capital of the world – Las Vegas.
  • Fruit Machine Slots: Fruit machines are a variant of classic slots. These are the games that were the first slot machines to launch back in the 1800s. As gambling for cash was illegal, players would win fruit sweets. Some online slot games offer a back-to-basics fruit machine experience, while others add modern features to the “fruity” aesthetic.
  • High Volatility Slots: If a slot game doesn’t land on wins often, but pays out big when it does, it’s known as a high volatility game. On the flip side, an online slot that pays out frequently but has small wins is known as a low-volatility game.
  • Megaways Slots: A popular mechanic created and licenced by Big Time Gaming, Megaways offers dynamic and random paylines. Regular online slots have fixed paylines, but Megaways offers “more ways to win” by increasing the rows on each spin. Megaways games can expand paylines to over 100,000 ways to win.
  • Video Slots: A broad term that signifies a slot game that uses modern video technology. The name was given to slots with screens that replaced mechanical slots in Las Vegas. It’s now also used for modern online slots with lots of features, video game-like graphics, and immersive gameplay.
  • Progressive Slot: A game that has a jackpot that grows on each bet/spin from every player. As the jackpot grows, it can reach huge amounts. When someone wins, the jackpot resets to a base amount and starts to grow again. Some progressive jackpot slots regularly pay out millions of pounds to winners.
  • Daily Slots: This type of slot offers different gameplay elements and winning possibilities each day. By changing the dynamics of the game daily, the slot feels fresh and exciting.
  • Drops & Wins Slots: A popular type of game that is pioneered by Pragmatic Play, Drops & Wins slots feature a random prize that can drop at any time randomly by using a random number generator (RNG). Importantly, you can still also win the standard slot paytable prizes, including the normal jackpot.

How Do Online Slots Work?

Online slots are interesting because playing them is easy, but they are complex in terms of gameplay and features. The good news is you can break slots into two sections: the base game and bonus rounds:

Base Game

When you visit slot sites and open a game to play, you will start in the base game. This is where you see the reels and symbols, and the goal of the base game is to match symbols on the reels, known as paylines. Different symbols in the game have different values, and the designs will change from slot to slot.
Even so, the goal remains the same – you must match the same symbols a set number of times to win different payout amounts. You will also see other symbols in many games:

  • Wilds: A wild symbol can substitute any standard symbol during a spin to help make winning combinations. Some wild symbols will also pay out on their own if you match them.
  • Multipliers: This type of symbol is available on some base games, and it literally multiplies the value of your payout. For example, if you win £100 but have a multiplier of 10x, the actual payout will be £1,000.
  • Scatters: This is a bonus symbol as the scatter usually triggers the free spins or bonus rounds when you match 3 or more. Some scatter symbols will also pay out in their own right.

Bonus Rounds

Bonuses are variable, but the most common is a free spins round. This is where you get extra spins to use without reducing your bankroll. Most slot games add “modifiers” to free spins, such as wild symbols, multipliers, or the ability to re-trigger the free spins. Some of the most common modifiers include the following perks:

  • Stacked wilds: Slots such as Eye of Horus allow you to stack wild symbols, which means the wild remains in place and could cover a reel or payline.
  • Random benefits: Most free spins bonuses have random modifiers, such as extra free spins, multipliers on spins, and random wilds.

Additional Slot Features

Some software providers enhance their games beyond the basics by using mechanics and gameplay features:

  • Tumbling/Cascading Reels: Known as different things by certain providers, this mechanic causes reels to drop down and add more reels. New symbols fall into place, potentially allowing you to stack winning combinations.
  • Respins: During the base game, a certain symbol or event can give you a respins of the reels with a modifier such as a multiplier.

UK Slots Regulations

UK Gambling Commission rules are strict for online slot sites and slot games. For example, slot games cannot offer Auto-Spin or Quick Spin features in the UK, even if that game has those tools in other regions. Similarly, UK regulations prohibit the ability to buy into a bonus. Many slots allow players to purchase access to free spins if they want, but this is not possible in the UK.
All these measures are related to responsible gambling. UK authorities believe that auto spin and buy-in features expose players to the dangers of excessive gambling.

Responsible Gambling with Online Slots

One of the reasons why we demand the casinos we list have a UKGC licence is because the regulator enforces specific responsible gambling commitments. We share those commitments and ultimately want all our readers to have a safe gambling experience.
Whether it’s betting in moderation or controlling your budget, the following tips can help you stick to responsible gambling ideals.

  • Pick a budget: The golden rule of gambling is to only use money you can afford to lose. Only you know how much that is, but it should be money that comes from your disposable income.
  • Stick to your budget: Setting a budget is easy; sticking to it is the challenge. Once you pick a reasonable amount of bankroll, learn how to walk away if you run out. If you master this technique, you will end each session either in profit or still within your set budget.
  • Don’t chase losses: We all know slots and casino games are based on luck, and when on a losing streak, it’s easy to assume your luck will change. However, chasing losses for “one more spin” is a fast way to eat through your budget.
  • Seek Advice: Never be afraid to admit you have a problem. Online casinos provide resources such as self-exclusive, deposit limits, bet limits, and time limits. Use these tools to manage your gambling safely.
  • Outside resources: You can reach third-party organisations directly from your online casinos. Notable examples include GamCare, GambleAware, and the Responsible Gambling Council. Each can provide advice and support for those who wish to control their gaming habits.

What is the best slot to play in the UK?

With thousands of slots available in the UK, definitively saying one game is the best would not be a true reflection of the options you have. Starburst by NetEnt is considered the most popular online slot game ever made.

What online slots payout the most?

Look for online slots with a higher Return to Player (RTP) rate. This means, on average, the slot payout back more of your investment over time. An RTP of 96% is average for online slots, but games can go much higher.

Can I win real money on online slots?

Absolutely. Slots you can play on UK casino sites are real money games that require you to risk your own money if you want to win. It’s also worth noting that many slots are available for free, but you cannot win real money.

Yes, the UK is one of the most regulated gambling markets in the world. If you choose a casino that has a licence from the UK Gambling Commission, you will have access to games that are independently audited for fairness and safety.

Online slots are completely random. All you do is press a button to spin the reels, and there is no method that guarantees wins.
