EVERYTHING YOU NEED TO KNOW ABOUT ONLINE SLOTS

So you’re interested in slots and haven’t picked a casino yet. That’s okay, because there are hundreds of casinos that allow players in the UK. It’s our job wade through the sea of options and help you find the best slot site for you. Our guides are designed to not only show you the best slot sites that UK players can join, but also what makes them the cream of the crop. We’ve done all of the heavy lifting so that you’re able to easily decide which site to head to.

As you’ll find with any of our casino reviews, we won’t just list the best sites; we dig into what makes an online casino “the best”. We’ll even help you figure out how much real money you could win playing at one of the casinos in our list. So, read on, learn about each site and make an educated decision on where to play online slots in the UK!

Let’s start out with our pros and cons of online slots:

Pros

Cons

Convenience – No one can argue the sheer convenience that comes with playing slots online. You can play from whenever you want, wherever you want, on any mobile device or on your desktop computer. It really doesn’t get any better than that. Less social – Yeah, playing online or through mobile can be a bit more isolating, but why not invite some friends over and play together? Or try live casino options or tournaments where they’re available to get that social fix.
Variety – The variety that comes with playing the best slots sites in unbeatable. There are thousands of different variations available at the click of a button. Something that would never be possible anywhere else. Technology – Technology can be hard to deal with sometimes. Freezing, skipping and the unreliable battery of a device can all have an impact on your slot experience. But don’t worry. Any online casino we recommend will be happy to help you if any problems arise.
Payouts – Did you know? Online slot games are known for having higher payouts and RTP than any other version of the game. This means that players win more often when they’re spinning the reels.  

SLOT VARIATIONS

Here are just a few types of the best slots online you will find while playing:

Classic Slots

Classic slots are exactly what you see when you picture a slot machine. It usually has three or five reels, a couple pay lines, and sure makes for a lot of fun. The classic variation of slots is one that we hold near and dear to our hearts because it’s a great option for both new and seasoned players. No tricks or surprises here.

Classic Slot

Video Slots

Video slots are one of the most popular variations of the game. Why? Well because of the digital revolution, of course! With technology, came a huge opportunity for video slots, and they became faster, more enjoyable, and just flat out easy to learn and play. With graphics that could blow your mind, and sneaky bonuses that make you want to keep playing, you can never go wrong with playing a video slot.

Jackpot/Progressive Slots

This is where things get really exciting. Developers will link many games, or sites together in order to create a huge prize pool. Every time money is wagered on one of those slots, a percentage goes into the pot and is up for the taking. Is it easy to win? No. But is it worth giving it a shot? Absolutely. The payouts on progressive slots are usually life changing amounts above £50,000 on slots like Mermaid’s Millions.

Jackpot Slot

Mobile Slots

Mobile slots are perhaps our favourite variation of the game. This is because they are made to play on the go, and that’s what we are all about here at TopMobileCasino, if the name didn’t already give it away. Play anywhere and everywhere (as long as you have a solid connection to the internet) and you should be winning in no time.

HOW ARE THE BEST SLOT SITES DECIDED

We’ve spent what feels like forever looking for the best UK slots sites. Our team of experts spends all of their time combing through all sorts of so-called “best slots sites online”. We review each one meticulously, weening out the good from the bad to make sure that if we’re recommending it, it’s perfect for UK players. There’s a list of criteria that we follow when we’re deciding if a casino belongs among the best sites.

Slots From Top Developers

We’re ALWAYS looking at what slots are on offer. Having thousands available is worthless if they’re from bad developers. That’s why we check to see that the sites are offering slots from the biggest companies. These are some of the top operators we like to see on the sites we review:

Microgaming – Everyone knows Microgaming. That’s just a fact. They are one of the most popular operators in the world, and are constantly releasing new, unique slot options for players. Not only that, but they created one of the highest paying progressive slots ever – Mega Moolah. Players have been known to win millions playing the best online slot.

NetEnt – NetEnt has made themselves one of the most popular and sought over operators in the industry. This is because of their innovative and unique gaming options that are massively popular through the UK. Ever heard of Gonzo’s Quest or Starburst? Of course, you have! They are both NetEnt games.

Playtech – Playtech is no stranger to the online casino game industry. In fact, they have become the number one choice for many UK players, and for good reason. Offering up progressive jackpots like Beach Life and Gold Rally, has been a very successful endeavor for Playtech, and we can only imagine what they’re going to come up with next.

Novomatic – Founded by Johann Graf, Novomatic is one of the oldest in the industry. They have become popular over the years for exporting their advanced gaming equipment around the world and for becoming a pioneer in in many ways. Just try Lucky Lady’s Charm for yourself to check out what their gaming experience is like first hand.

IGT – International Game Technology, or better known as IGT, has been in the industry for years now. With many firsts under their belt, they are one of the most well-known operators not only in the UK but in the world. Candy Bars, Siberian Storm Dual Play and Cats are just a couple of their more popular games.

NextGen – For 17 years now, NextGen has been an industry leader. With hundreds of games both on and offline, players would be hard pressed to visit a casino without NextGen games waiting to be played. One of our favourite games, Merlin’s Millions was developed by NextGen, along with Medusa and 300 Shields.

Barcrest – Would you believe us if we told you Barcrest has over 50 years’ experience in the industry? Well they do. They began in 1968 and have been taking the gaming world by storm ever since. Action Bank, Boulder Backs, Rainbow Riches and Pots of Luck are some of the top games that they offer.

Real Time Gaming – Real Time Gaming (RTG) has a philosophy of “We take gaming seriously.” And they prove it time and time again. They offer many different slot variations for players. And with some of their most popular slots including High Roller, Big Shot and the Three Stooges, RTG is a must have operator in any decent online casino.

The best slots don’t just come from the big developers though – we’ve got our ears to the ground looking for the next up and comer’s too.

At the end of the day we’re looking for a seamless blend of quality and quantity like a beautiful blended scotch. For us, the best sites have huge game libraries that are constantly updated and curated.

Casino Games Other Than Slotsassorted casino games inlcuding blackjack, roulette, and craps

We wouldn’t be doing our jobs if we weren’t considering the multisport casino athlete. What if you’re a fan of slots but like to play other games like roulette, blackjack and video poker. Any site that you see recommended by our team will offer all of that and then some, including exciting things like live casino games. If we’ve done our job right, there will be something for every online gambler.

Big Casino Bonuses For Everyone

Just about every online casino on the planet offers bonuses and why wouldn’t they? After all, what player wouldn’t want a big juicy bonus? From welcome bonuses, to reload bonuses all the way through to free spins on a specific slot. There’s a bottomless pit of offers that we consider when evaluating a site. One of the most important things we look for is a loyalty program. If you’re going to be playing with your hard-earned money, why not earn something extra?

The Important Stuff Behind The Curtain

We covered the glamorous aspects of grading a casino, but there are other major criteria too:

  • Customer Service – Is it responsive? Do they offer it 24/7?
  • Security – Are your transactions SSL Encrypted? Is the casino licensed?
  • Banking Options – What deposit methods are available? How quick can you withdraw?

It is our job to cover all of these areas so that when it’s time, all you need to do is join the site of your choosing and start spinning the reels! After all, you could be one spin away from winning a fortune!

What Slots Can I Play at the Best Sites?

The best sites will offer a large array of slots. Like we mentioned above, they can be broken down into a few basic groups. We’re going to take a look at video slots, classic slots, and progressive slots, in a little more detail below.

Slot Machine with jackpot

The slot we see the most is the video slot. When you hear us talking about the best slots online, we’re usually referring to these. These games are characterised by having animated reels, fun bonus rounds and multiple paylines. In fact you can find slots with up to 1024 paylines.  There loads of fantastic video slots for you to play, however some of the best includes:

  • Game of Thrones (Microgaming)
  • Planet of the Apes (NetEnt)
  • Guns N’ Roses (NetEnt)
  • Gladiator (Playtech)
  • Thunderstruck II (Microgaming)

The next slots to look at are classic slots, and these more closely resemble the fruit machines of old – simpler games with only a few pay lines and no real bonus features to mention. Often times you will find these with 3 reels. Some might find these slots to be incredibly boring, however, others yearn to play simple slots, without all the bells and whistles offered by the majority of slots nowadays. Some of the best classic slots are:

  • Sultan’s Fortune (Playtech)
  • Twin $pin (NetEnt)
  • Sizzling Hot (Novomatic)
  • Triple Red Hot 777 (IGT)
  • Pharaoh’s Fortune (Microgaming)

Finally, there are the progressive jackpot slot machines. These big kahunas, like we mentioned, are the ones that offer the biggest prizes. Some people have been lucky enough to win over £10,000,000 on a single spin. The best progressive slots all have jackpots that regularly exceed the £5,000,000 mark. If you want to play one of these progressive jackpot games, check out the likes of:

  • Mega Moolah (Microgaming)
  • Mega Fortune (NetEnt)
  • Age of the Gods (Playtech)
  • Major Millions (Microgaming)
  • Jackpot Giant (Playtech)

Regardless of the type of slot you prefer, you should be able to play for free before risking any of your own money. Free slots have all the same features as real money slots, including bonus round features, all without having to stake any of your own money. It’s a great opportunity to try before you buy and make sure that a slot, or any other casino game for that matter, is right for you. Don’t play for free for too long though, as you’re missing the opportunity to win a massive jackpot!

Can I Use Bonuses to Play Online Slots?

To put it simply, YES! A thousand times yes! Bonuses are a huge part of the experience of playing at the best online slots sites. Players will often use these bonuses as much as possible. In fact, these bonuses are best used on slots. That’s often because of how other games like blackjack or craps are counted towards a bonus’ rollover requirement. So, your best “bet” is to use your bonus to play slots.

A rollover requirement, also know as a playthrough or wagering requirement, is essentially how many times you will have to bet your deposit + bonus before you are able to withdraw your winnings. Online slots often contribute at 100% of your wager, but a game like craps can be as low as 5%.

For those new to online casinos, the most important bonus is always going to be that first deposit bonus, aka the welcome bonus. It can almost always be used to play slots and sometimes will even come with free spins on a specific slot machine. The ability to play for free is a great way to learn how to play the game, while giving yourself a crack at winning some real money at the same time.

We also mentioned loyalty programs above. Playing online slots is quite often the perfect way to earn loyalty rewards. The quick gameplay allows for a quick points buildup. Depending on the site you are playing at, these rewards come in all kinds of different shapes and sizes, from free bonus funds to earning back a percentage of your losses. Each site’s loyalty program is different, so before you sign up, make sure you read the terms and conditions.

Are the Jackpots High at the Best Slots Sites?

The jackpots aren’t just high – they are sometimes astronomically huge! The biggest prizes are found at the progressive slots, with the two largest usually being Mega Moolah and Mega Fortune. The reason these jackpots get so high is simple: the jackpots keep rising as more and more people play them. This happens until one lucky player hits the jackpot. All progressive slots will have a counter showing the current jackpot amount, so you can pick the one with the biggest jackpot at the moment.

When it comes to progressive jackpots, it doesn’t matter which site you play at, as the progressive jackpot game is linked across all sites. This means that you don’t have to head to the same casino as everyone else, but can instead head to the casino you think is best, and still have the chance to win a massive sum of money. Players in Australia are contributing to the same jackpot that someone playing at an online casino in the UK is.

But how can you give yourself the best chance possible of winning a jackpot? Well, the best online casinos will publish the RTPs of each and every slot they offer. RTP, which stands for Return to Player is expressed as a percentage and is the long-term average of what you’ll win back over time. The higher the percentage, the more chance you’ve got of winning. So, if a slot has an RTP of 98%, you should expect to get back, on average, £98 for every £100 you spend. This means that this slot offers you a better chance of winning than one with a 95% RTP. So, check out the RTPs before you start spinning the reels and watching the symbols land in place.

Can I Play Slots with a Mobile Device?

playing slots on a mobile phone

You certainly can – in fact, a site won’t make it onto our list of the top UK slots sites if it doesn’t have a really strong mobile offering. After all, our site is called Top Mobile Casino. The best mobile slots in the UK are on sites that adapt the screen to fit any mobile device. The mobile casino should allow you to control everything using your device’s touchscreen. You won’t find quite as many slots on a mobile site, however, the selection should still be large, and encompass the three different types of slots mentioned further up this page.

Mobile gamblers should also find that they have access to the same features as desktop players. So, you’ll still be able to use your preferred payment method while gambling from your mobile, and will also be able to contact customer support. You’ll be able to play at nearly all mobile sites by accessing the site using your mobile browser. Some sites even offer a mobile casino app, which makes gambling with a mobile easier than ever. So, if you own a smartphone or tablet, you’ll definitely be able to pay at the best online casinos in the UK.
