Finding slot machines to play is not the same as finding good slots to play online.

Although online casinos list a lot of games in their slot machine section, not all games come with the same level of gameplay, graphics, and RTP.

If you are a player from the UK and you want to access the best slots to play for real money, there are a few things to consider.

The UK Gambling Commission regulates gambling in the country with an iron fist.

Only legal and regulated UK online casinos with audited platforms and operations (not to mention bonuses with clear terms and conditions) can pass the UKGC checks, obtain a license, and offer gambling services to the UK players.

While that limits your options for playing online, it does make the available choices more secure and trustworthy.

When you see that a casino is licensed by the UK Gambling Commission, you know you can feel safe there.

Yet, that doesn't solve the initial dilemma: which video slots should you play from the UK?

The PokerNews Casino analyzed the best UK online casinos to create a list of the top slot games you can play from the United Kingdom.

Best UK Slots to Play for Real Money

First, let's start with some of the best games to play if you like real money gambling.

Keep in mind that gambling for real money is a slippery slope and you should always do that responsibly. If you are not sure about what responsible gambling really means, check out this page.

P.S. Did you notice that most of these Slots have old release dates?

It takes months or years to discover which are the best slots to play, especially when the RTP is not the only criteria to consider.

Moon Shadow

Developed by Barcrest and has an RTP of 98.1 percent.

Need any reasons to consider this game?

• A trustworthy developer? Check
• An above-average RTP for UK slots? Check
• Free spins feature, wilds, and scatters? Check

Jackpot 6000

Jackpot 6000 features a jackpot and the highest RTP of all the slots on this list: 98.9 percent.

Not only this is an old slot, but it also resembles the most classic slots of all time.

You'll see and hear a typical slot machine on your screen. Shiny lights and retro sounds, classicly listed payouts and buttons, and three reels filled with fruit symbols.

There's also a casino in the background to make you feel as if you're in one.

It may not be the slot with the most fascinating graphics or advanced special features but it's not a bad one at all. Read more about Jackpot 6000 Slot here.

Queen of Riches

A Slot with a unique layout and high RTP? Yes, please!

Best Online Slots Casino Games

Here comes the Queen of Riches. Having a reel structure that mixes up the number of rows from spin to spin and an RTP of 96.9 percent.

Also, this Slot has high volatility. This means that the wins will not be very frequent but the wins are of higher value compared to low volatility games.

Frozen Inferno

I love hell-themed Slots. Burning fire, magic runes, skulls, and potions.

While horror movies are (sometimes) scary, such themeswork very well on slot machines. A

Frozen Inferno has 40 paylines and an RTP of 96.36 percent.

Fortunes of Sparta

One of the best graphic adventures on slots. Swords, warriors, beautiful women, ancient Greek vases and ships. All set in a golden background and accompanied by calm tunes.

Blueprint Gaming did their best to bring the times of Spartacus to the world of UK gambling. And if you are a fan of gladiators, Sparta, or anything Greek, this is a game you might want to try.

Especially, since you can play it for free after registration.

Best FREE Online Slots for UK players

You don't need to spend money on slots unless you want to. All UK casinos offer demo slot machines to play for free credits that are as fun and interesting as the real money ones.

To access these games:

• Register a free account
• Confirm your age

Please remember to gamble responsibly even when you do so with play money. The fact you don't win / lose anything is not a good reason to treat gambling lightly and play too much.

The list below features best free online Slots for UK players. If you are looking for something interesting to play, you'll find it here.

The Final Countdown

The 80s was a good decade for music. Many songs are still popular and are played on many occasions worldwide.

The Final Countdown by Europe is one of them.

The song is so iconic that more than 30 years after its release it got itself a Slot machine.

Not too bad for a song, huh?

Inspired by Europe's music, Big Time Gaming created music and diamonds-filled six-reel Slot.

It reached online Casinos in the middle of March 2019 and awards the players with an RTP of 96.65 percent, up to 15 free spins, and up to 888x multiplier

Phoenix Sun

Quickspin already proved itself as one of the best online Slot developers and Phoenix Sun Slot shows why they deserve that title.

The game has good graphics, animations, and sounds. The symbols accurately depict Ancient Egypt and every win triggers a Respin feature.

When you trigger Free Spins, your reels expand and instead of the initial 5x3 234-payline structure, you spin five reels with six rows in total.

The Equalizer

If you're into arcade games or futuristic Slots, The Equalizer Slot is the one to play.

The Equalizer is a new Slot game by Red Tiger Gaming, based on the arcade game by the same name.

It takes you to a neon world of expanding reels, free spins, and wins up to 10,000x the stake.

Kiss

When some people hear the word Kiss, they think about romance or their significant other.

When others hear it, “I was made for loving you, baby” starts playing in their head.

Best Online Slots Casino Usa

I may relate to the latter group more but that's not the reason Kiss Slot from WMS is on this list.

Developers blessed this UK slot machine with a unique reel structure, 100 paylines, and a decent RTP. They must have been the big fans of the band.

And if you are too, you will enjoy this Slot whether you play with free money or real cash.

Money Matrix

What happens when Matrix meets retro Slots? Money Matrix Slot happens.

Money Matrix is a retro Slot with three reels and three rows. Featuring the classic Slot symbols - 7s, single, double, and triple bars, and a dollar sign.

At the same time, it features Matrix-like fonts, symbols, and background, so the movie fans will find some connections as well.

The most unique feature of the Slot machine is called the Nudge.

Best Mobile Slots to Try This Year

The best Slots games online for UK players wouldn't be the best if you couldn't play them on your phone.

All the above-mentioned games are compatible with smartphones and tablets. But here are a few games that you simply must have on your mobile device.

These are all real money UK Slots and they are available at mobile Casinos.

Wild Mantra

Yggdrasil's Slots are always exciting and mobile-friendly, so some bound to appear on this list. And one of them does.

Wild Mantra is one of the newest Slot by Yggdrasil. It features Oriental theme, high RTP (96.3 percent), and lovely five-reel four-row structure with 25 paylines.

The Slot has both Respin and Free Spins features, plus, sticky wilds.

Secret Trail Match 3

Secret Train Match 3 is not exactly a Slot but very similar game you can play for real money.

You've probably already played similar games or still have some on your phone.

The rules require you to match three or more identical/same-color symbols, so they'd go p-o-o-f and disappear from your screen.

Where does gambling come in?

Each move you need to make a bet. Different symbols have different values, each worth from 0.01 to 6. The bets start at 0.02 and go all the way up to 50.

Paranormal Activity

Paranormal Activity is a Slot based on the horror movie series of the same name.

As you can guess from its name, it features ghosts and other types of paranormal beings. But that's not the spooky part yet.

The creepy background noises and glitchy images are. As for the things that go bump in the night, they may very well be your lucky charm.

Especially since the bonus symbols trigger the Bonus wheel which awards you with one of the following:

• Paranormal Spins - unlimited spins until you get five wins, each with an increasing multiplier
• Possessed Spins - 10 FS with stacked wilds
• Demon Spins - 15 FS with extra wilds
• Instant Wins - immediate cash prizes

Wild Times

While all the mentioned online Slot machines UK are worth your time, you may be interested in something more classic and less feature-packed.

If that's so, give Wild Times by Barcrest a try.

Best Online Slots Casino Uk Casino

It's a three-reel fruit machine Slot bursting with classic symbols, such as golden bars, lemons, cherries, bells, and watermelons.

It has only 5 paylines and low bets, starting at 0.10 per spin. If that's all you need, it's all you need to know about the Slot.

Bier Haus

There's one event every fan of beer wants to attend: the Oktoberfest!

The best way to enjoy it would be spending October in Germany. But if that's not in your plans anytime soon, play the Bier Haus Slot by WMS.

You'll hear traditional music, see a pub in the background, and beer in barrels and pints, and, of course, stereotypical German characters. There is nothing more like Octoberfest than that.

Gamblers worldwide should envy UK players – they have one of the most organized online gaming markets, huge range of licensed and reputable online casinos and endless variety of games to play.

Despite all that, not all UK casinos are truly good. Online casino industry is no different from any other. As you have great restaurants with delicious food at reasonable prices, there are ones you wish you haven’t entered. Similar with online casinos. 10% are great, 70% are mediocre and 20% should be avoided.

The ones that scored perfect on every test we made and most importantly, then ones we can vouch for; that they are fair and safe, pay winnings in a smooth and fast fashion and offer a wide range of casino games and promotions for you to enjoy from.
