TOP Real Money Online Slots You Can Find at The Best UK Sites

Starburst Slot

NetEnt’s classic Starburst is a 10-line game with low volatility and an RTP of 96.10%. You must line up shining gems in this space-themed slot to win a payout. But the Starburst Wilds are the real stars here. These wilds appear on the middle three reels only. When they appear, they will expand to fill the whole reel. They will then hold in place while the other reels re-spin—play Starburst at Mr Green Casino App.

Gonzo’s Quest

Gonzo’s Quest is an Aztec-themed slot introducing the Avalanche feature to players. Every time you land a winning combination, it will explode from view. The winning symbols then disappear and allow the ones above to drop into their place. And with every successful avalanche, a progressive multiplier will be added to your win—play Gonzo’s Quest at Ladbrokes Casino with a free spin promo.

Divine Fortune

Divine Fortune is one of NetEnt’s most popular jackpot slots. The Greek myth-themed slot has 20 paylines and an RTP of 96.6%.

Betfred Slots

With over 50 years of gambling industry experience behind them, Betfred has established itself as a trusted name in the business. The casino site offers more than slot play, so a choice of 320 slot games is low on the variety scale.

Betfred makes up for the lack of games with a wager-free bonus of 100 spins and a £5 minimum deposit. Since no playthrough requirements exist, you can keep whatever you win with your bonus spins. Deposits and withdrawals get processed without delay once verified.


Established in 2011, garnered an excellent reputation for trust and variety. A choice of over 3000 slot games might seem overwhelming, but this is among the best sites if you like to change things up.

Videoslots will match your first deposit up to £200, plus they add free spins. However, note that these bonuses require a 35x playthrough before you can cash out any winnings.

Videoslots has won several gaming industry awards because it offers more than an abundance of choice. The online gambling site holds regular freerolls and slot tournaments. Its loyalty program is second to none, which is why it’s among the best slot sites the UK has ever seen.

The graphics might look outdated by today’s standards, but Videoslots knows how to keep customers interested. First, the operator sets goals for players to achieve to unlock new and exciting slot game experiences. Then, add a lightning-fast deposit and withdrawal process; you have one of the best slot sites to play.

Playzee Slots

Among the new slot sites, this one established in 2018 has gained a reputation for fast and friendly slot play that is virtually unlimited in scope. Choose from a massive catalogue of over 3300 games with a bonus structure to rival any competition.

Get matched up to £300 on your first deposit, with 100 free spins. The fun doesn’t stop there, as Playzee offers daily bonuses and Zee points. Get £5 for every 1000 Zee points you collect, and on Sundays, free spins get awarded to lucky players.

Despite the 35x playthrough requirement, there are plenty of ways to enjoy the Playzee experience with the best new slots and favourites offered anywhere. Withdrawals get processed within 2- 24 hours and have no fees, so you never keep waiting long to reap the winnings.

Players love the easy-to-use interface that is mobile-friendly and pleasing to the eye. Playzee might be a relative newcomer, but it has become one of the best slot sites the UK has available because of its funloving atmosphere. You have to experience brand ambassador Zeegmund to understand the difference.

Of course, when you hit that big jackpot, you will want to get your winnings as fast as possible and with minimum fees. The best slot sites UK players use will get your money to you quickly and easily.

Casino Game-Specific Bonuses

Most bonus offers apply to a range of games at online casinos. You might be able to play slots (including Megaways) or table games as long as they feature in the approved games list. For example, Dream Vegas Casino offers free spins bonuses on Starburst, Gonzo, Aloha, Twin Spins and eligible NetEnt games. The maximum that you get is 150 free spins with a 35x wagering requirement.

Slot Sites with Best RTPs

ECOGRA performs testing, and you can view a complete list of RTPs for all supported slot games.

What Makes the Best Slot Online Websites and Apps?

While many casinos like Amber Spins and XL Casino have years of experience providing gambling entertainment, new slot sites bring added features. First, you must know that your slot sites are secure and respectable. Yet, once you have established an online gambling site’s credentials, the critical factor becomes the value for your money. 

Three main criteria determine the best slot sites. 

  • A variety of games is the essential draw that keeps your interest. New slot sites attract players with new slots that are not offered by competitors.
  • Promotions and bonuses are other essential facets of a positive online gambling experience. For example, most of the best slot sites in the UK provide deposit bonuses and free spins. But as you will see, not all bonuses are created equal. 
  • If you know how to use slot sites, you will recognise the variance in playthrough requirements between slot sites. Some slot sites go beyond welcome bonuses to offer reload bonuses and regular promotions. The banking features associated with the site are the other factor determining one of the best slot sites. It would be best if you had several options for depositing your bankroll. Many new slot sites offer deposits and withdrawals through PayPal or with cryptocurrency.

Types of online slots and casino games

  • Classic Slots: Top original slots often resemble nostalgic 3-reel games in Vegas casinos. There are usually only one or two pay lines and a single bonus round at best. You’ll also find fruit machines that resemble your favourite games from the pub or amusement arcade. Try fruit slot machines, use apps (Rhinobet casino) and get bonuses.

Online Slots Features

The online slots operate similarly to the classic physical slot machines but are available via online casino sites or mobile apps. The best UK online casinos boast a massive array of different variations and game types. Take your pick of fruit machine-style games or load up the latest HD 5-reel game bursting with a bonus action. All good slots come with at least one bonus feature. It might be as simple as a wild symbol or incorporate free spins, multipliers, and more.

  • Wild Symbols
    Wilds are like joker symbols that help you to complete a winning pay line. Wilds can also act differently depending on the game. Walking wilds will shift across the screen while the remaining reels respin. You can also find features like replicating wilds and expanding wilds that stretch to fill the entire reel in modern slots.
  • Scatter Symbols
    Scatters are symbols that pay out wherever they land. You will also activate a bonus feature by landing three or more scatters anywhere in view.
  • Free Spins
    A free spins bonus is the most common type of slots feature. Win free games by landing scatter symbols, and retrigger the feature by landing even more scatters.
  • Multipliers
    Multipliers help to boost your payout during a bonus round. The multipliers can come attached to free spins, or they may appear as special symbols on the reels.
  • Cascading Reels
    Many developers offer slots with cascading reels. They can also be called Tumbling Reels, Avalanche Reels, and Falling Reels. After a winning cascade, the symbols are removed to allow the symbols above to drop into their place. You will then be awarded a respin. You may also win a prize multiplier on any winning cascade you’ve hit.

How to Play Slots and Win Money?

It’s easy to get started playing online slots at a UK casino. You can try games for free or make a deposit and spin the reels for real money. Online slots vary, but the best casinos offer a choice of hundreds of top games. Some feature exciting bonus games, while others give you a chance to aim for a big-money progressive jackpot.

  • Step 1: Choose Your Coins & Paylines
    Click on the slot you want to play to open it in your browser window. Some casinos also let you download slots to your desktop for more reliable gameplay. You’ll have to select the number of paylines you want to play plus a coin value. You can also hit the ‘max bet’ button to jump straight to the top stake value. 
  • Step 2: Spin the Reels
    Once you’ve chosen your bet size, hit the ‘Spin’ button. A set of vertical reels will spin and stop at random. Spins are random and governed by a computerised random number generator (RNG). There are no such things as hot and cold streaks, and each slot spin is independent of the previous one.
  • When the reels come to a stop, if you’ve lined up matching symbols on one of the paylines, you will win a cash prize. Paylines usually run left to right starting at the first reel. However, some slots pay along all possible win lines.
  • Step 3: Trigger a Bonus
    Most modern online slots offer a bonus round. You can trigger this by landing special ‘scatter’ symbols which also award a cash prize when they appear on the reels.
  • Step 4: Withdraw Your Winnings
    Any winning spin is immediately credited to your balance. You can exit the game at any time and return to the lobby. You’re free to use your balance on other games or cash outto a debit card, bank account, or e-Wallet.

Online Slots FAQs

What is Volatility & RTP in online casino slots?

Every slot has volatility. It’s the frequency with which a game pays out jackpots or triggers bonuses. High-volatility slots may pay out large jackpots, but they’ll come infrequently. Low-volatility slots tend to pay many smaller prizes, but bonus features may be small or non-existent.
The RTP is the return-to-player percentage. You’ll usually find this information in the slot’s paytable. It relates to the expected return made to players over millions of spins. The higher the RTP, the better the average payouts are for players.

What are the most popular slot games?

Some of the most famous slots to play online (among British casino gamblers) are Immortal Romance, Lucky Lady’s Charm slot, the Book of Ra game series, Sizzling Hot, Starburst and Age of the Gods.

Best casino apps to play slots?

All UK’s top slot casinos offer mobile apps. Download for free and install on your iOS and Android smartphones one of the best casino apps in the UK. Play slots with William Hill or bet365 mobile casino apps.

What is a free-to-play slot?

A good rule of thumb is to try free-play slots first. Load the ‘Practice Play’ version of the game to your browser or mobile phone. You’ll be given several free credits by the casino to use on the game. There’s no financial risk, but you won’t win any cash. You can decide which games you want to play for real money by trying free play slots. Get a feel for a game’s variance and see if the bonus features are easy to trigger
