About Slot Sites

If you’re a fun-loving gambler then slots might be just the thing for you. With literally thousands of games to choose from and the constant addition of new titles, you’ll never get bored. With innovative gaming software such as Microgaming, Netent and Playtech we’ll never be short of new slot games and innovative new ideas in this category.

In a saturated market, the only way for slot sites to stand out amongst the crowd is to improve the level of gameplay through technology and graphics and strive to add more interesting slot titles to their repertoire.

Slot sites are held at a higher bar because gamers expect better quality and experience of gameplay than traditional table games such as Blackjack or Roulette. There’s one thing creating a great experience but it’s another ball game attracting players and keeping them, that’s why an online casino’s best asset is to use attractive slot bonuses to grab your attention, but need to offer slot reload bonuses and rewards to keep them.

  • Why Do Gamblers Love Slots?

    Slots are much easier to learn for the average player. Whereas table games such as Blackjack and Poker require a level of skill, slots, however, can be played by anyone over the age of 18 with absolutely no experience ever gambling before. It is down to the luck of the draw on each spin and the excitement that goes along with potentially winning the jackpot. Slots do come with a higher risk than table games, but equally the payouts can be much bigger if you win, which is the main attraction.

  • Slot Software Providers

    If one thing is for certain it’s that slot sites are heavily dependent on advances in technology by their slot game providers to ensure they’re kept up to date. The software providers that fuel slot sites are geared towards creating the best experience possible for mobile slot players through usability, gameplay and speed. With constant developments and technology advances, slots are easily one of the most heavily invested and tested gaming categories online. When assessing online casinos’, we like to see the best slot providers in the market such as Microgaming and Playtech which we know are going to move heaven and earth to develop the very best games money can buy!

  • Variety of Slot Games

    Due to the sheer volume of slots available, you’ll never fall short of choice. We’ve seen titles mirroring the most popular movies, series, comics, celebrities, and artists. For example, Marvel has created slot games out of all of their blockbuster movies such as Thor, Iron Man, The Hulk, and most recently The Avengers which broke box office records around the globe!

Slot Bonuses in 2019

Not all online casinos offer specific slot bonuses, but we’ve done the rounds to find the best of them. We’ve found the top slot sites in the UK to bring you the best bonuses which can be used on slot games.

Traditionally online casinos would offer a general cash welcome bonus, whereas you now have a wide selection of bonuses tailored to a variety of games, such as live dealer roulette, blackjack and of course slots, which is what we’re focussing on here. This allows players to be much more selective about where they would prefer to spend their bonus cash.

Slot Bonuses can either be in the form of a cash sum or free spins. The most common no deposit slot amounts tend to be between £5 to £20. If the casino opts to offer free spins as opposed to cash, then we tend to see anywhere from 5 to 50 no deposit spins. First deposit slot bonuses can vary widely, but we tend to see much larger amounts offered since you have to deposit to receive the funds. We’ve broken down each slot bonus type below so you can choose which one you prefer.

  • What Are No Deposit Slots Bonuses?

    These types of bonuses are extremely popular since you don’t need to make a deposit. Players go on the hunt in their masses to find the best no deposit slots around the UK, but we’ve cherry-picked the best already! No deposit slots often come with high wagering requirements and a maximum win limit. Some casinos even allow you to keep the winnings and might even offer no wagering requirements, which means that you don’t need to bet any of your own money to cash out the winnings.

  • What Are First Deposit Slot Bonuses?

    On a first deposit, you’ll tend to get a bigger slot bonus since you’re depositing your cash. The bonus can either be specifically applied to slot games or you’ll find that you can use a welcome deposit bonus which can be used on any game, which includes slots. In this case, slots tend to contribute a higher percentage, more often than not 100% towards your wagering requirement because they carry a lot more risk than traditional table games like Blackjack and Poker. The obvious benefit of playing through slots as part of your welcome bonus is that you have a larger variety of slots to choose from.

  • How Can You Claim a Slot Bonus?

    Claiming your bonus is pretty simple as long as you haven’t registered with the casino before, and are over the age of 18. We’ve listed the steps you need to take below to claim your very own:

    1. Take a look at our top list of slot bonuses on this page and choose your preferred casino.
    2. Head over to the casino, check the bonus offer along with the terms and conditions.
    3. If you’re happy with what you see, sign up by entering your personal details.
    4. Depending on the offer, if a deposit is required then make your qualifying deposit amount.
    5. Simply claim your offer once your deposit has been made and check your balance to ensure you’ve been credited the bonus amount.
    6. Choose your slot game to play with your bonus money or free spins and most importantly, have fun and gamble responsibly!

  • How Can You Decide Which Slot Sites Are Best?

    Well, the good news is that we’ve spent the time reviewing all UK based casinos to find the best slot site so that you don’t have to! So what is it that we expect from a great slot site in the UK?

    • Providing slots from the best providers – Any good slot site should have slots from the best software providers such as Microgaming, Playtech and Netent. From experience, we know that these providers spend a lot of money on creating the most innovative slot experiences online, which is why it’s so important for casinos to have them in stock.
    • Mobile functionality – The beauty of playing slots is that it doesn’t require too much concentration or skill, simply spin the wheel and off you go. For that reason, slots are extremely popular on mobile devices since they can be played so easily on the move. As such we place a lot of emphasis on the usability, graphics and playability on mobiles, this is a must for any good slot site.
    • A large variety of games – Although we’re clearly being biased to slots, we think that a good casino should provide a whole host of games to enjoy.
    • Great promotions and regular bonuses – Having a great welcome bonus go without saying, but we expect a wider selection of bonuses either on sign up or loyalty and reward bonuses for sticking around and spending your money with them.
    • Security – Having a great security system in place is paramount to ensuring players feel safe and their money is protected. We look carefully at their security certifications, licensing and customer support when assessing the overall security of any slot site.

    Once you’ve read the reviews, select your preferred slot site, sign up and spin the reel!

  • Which Slots are Available at the Best Slot Sites?

    Where do we start!? This is all down to personal experience since every player has different needs than another. From the good old days of playing traditional slot machines at glitzy land-based casinos, slots have come a long way. Let’s take a look at the most popular slot types and what they have to offer.

  • What Are Online Video Slots?

    It’s no surprise that video slots are the most popular slot category online. With a huge range of games, animations and graphics, video slots have made it easy for the everyday player to spin the reels anywhere, at any time and have a blast doing it!

    There is no limit to how often you want to spin the reel when it comes to video slots, you can play as many times as you like, no matter what time of day! Although there is nothing compared to a brick and mortar casino experience, slots have done an incredible job in making you feel like you’ve stepped into one.

    Video slots also offer additional bonuses, higher bets, and more pay lines. With incredible graphics and gameplay, whilst keeping up to date with pop culture, video slots will always have an attractive proposition for players and keep them coming back for more.

    Some of the most popular current titles include:

    • Starburst
    • Gonzo’s Quest
    • Iron Man 2
    • X-Men
  • What Are Classic Slots?

    There’s something about the word “classic”; an air of elegance and authenticity come to mind. Playing classic slot games often brings you back to your earlier years, which might feel like a long time ago depending on how old you are!

    Reminiscing about the days when going to the casino with your friends was a semi-big deal and a real-life experience, and for this reason, some players love classic slots over new online slots since it brings back those fond memories.

    In the UK classic slots are usually played on the fruit machines after a couple of pints at your local pub, the classic themes have been around for donkey’s years and their uptake doesn’t seem to be slowing down either. Now you can play them as free slots online and don’t need to worry about gambling your own money to enjoy them!

    With 3 reels and a variety of fruits as symbols, the simplicity of gameplay on fruit machines is why they’re inherently popular. All of the slots sites we’ve listed on the page will include some popular classic slots like:

    • Penny Slots
    • Irish Gold
    • Lucky Diamonds
    • Lucky 8 Line
    • Ace of Spades
    • Joker’s Jewels

    Although all of these slots can be enjoyed for free, if you feel like being a bit more adventurous you can also play for real money by signing up to a trusted slot site and depositing some money!

  • What Are Progressive Slots?

    Next on the list are progressive slots, where you can potentially get a life-changing payout by winning a jackpot. Progressive games don’t have a limit, whereas the majority of video slots will have a maximum limit on what they’re able to payout, but how does it work?

    A small proportion of each coin that is inserted is used to fuel the total jackpot amount. So essentially the more it’s played the bigger the jackpot becomes. We’ve seen players win £500,000 all the way up to a staggering £20 million! We’ve listed some of the most popular progressive slots below:

    • Mega Fortune
    • Hall of Gods
    • Mega Moolah
    • Arabian Nights
    • Mystic Fortune
    • Lucky 8

    Whichever slot type you choose, we always recommend that you first try them for free and once comfortable, deposit your own money and start spinning!

  • Why Are Slot Jackpots So Attractive?

    The incredibly high jackpots offered in progressive slots are often the most attractive among players, winning such a large amount is a close comparison to winning the national lottery so you can see why! As of today, the current jackpot amount on Mega Moolah stands at £2.5m and Mega Fortune with a jackpot amount of £2.4m. The latest winners received £4.4m and £3.4m retrospectively, which are humongous wins!

  • How Can You Increase Your Chances of Winning?

    All slot games carry a metric called RTP, which is called the return to player percentage. This value states your odds/chances of winning on the online slot of your choosing. In basic terms, the higher the RTP percentage, the more likely you are to win.

    Let’s take a quick example to show how it works, Slot A has an RTP value of 98%, meaning that if you were to deposit £100, you would win back £98. The remaining 2% is what the casino refers to as the house edge, essentially the casino’s profit from your wagering. Now, having this information, which top 10 slots have the best RTP percentages for you to wager your money?

    1. Ugga Bugga: 99%.
    2. Ooh Aah Dracula: 99%
    3. Mega Joker: 99%
    4. Blood Suckers: 98%
    5. Jokerizer: 98%
    6. Big, Bad Wolf: 97%
    7. Jack Hammer 2: 97%
    8. Devil’s Delight: 97%
    9. Starburst: 96%.
    10. Rainbow Riches: 95%
  • Playing Real Money Slots

    Once you’ve had a feel for the online slots that you’ve had your eye on and you’re ready to play for real money, simply make a deposit, launch your preferred game and spin the reel! If it’s your first time signing up remember to grab your slot bonus which should give you a helping hand or at least give you some free spins before you start dipping into your real money funds.

  • How can you play slots on your mobile?

    Having the functionality to play slots on mobile phones is practically mandatory now. Since the majority of online casino traffic comes through mobile devices, if a casino doesn’t offer mobile functionality then they’re either very outdated or haven’t grasped the importance of the user experience.

    All of our top slot sites that have been listed on our  website have been assessed for their mobile experience since we understand the importance of being able to play on your mobile, whether that’s at home, or on the go.

    Online casinos either offer a downloadable app as a separate version of their online casino or a mobile responsive version which doesn’t require a download. This means you simply access the casino site from your mobile device and the casino will serve you a mobile version of the site, as opposed to the desktop version, making your experience much more tailored to the device that you’re on.

    When reviewing mobile slot sites, we look at all aspects of the user experience, particularly the ease of navigation, gameplay and support. You should have access to all of the slots that you would have on your desktop machine, on your mobile.

    We look for a seamless transition into mobile since we want to have the same experience as you would be sitting at home playing on a bigger screen to playing on a smaller mobile device. Best of all, the flexibility of playing on the move means you can access online slots at any time, as long as you have a wifi connection!
