Why Play Casino Slots Online?

Online slot games are now the most played part of any online casino making up over 80% of all games played worldwide. This has grown year after year as players move away from table games into the bright lights, bonus rounds and features of slot games.

Now we live in the digital age where everything is available at our fingertips; this has allowed players to access slots on their mobile phone, tablet, or PC without needing to visit the local casino. Time may play a factor in visiting your favourite slot sites on your device as this proves much easier, plus the ability to access many more games than in the local bricks and mortar casino.

The online aspect allows you to log in as and when you want and start playing. Some claim that this eliminates the fun of pressing buttons or pulling the lever from these games, but many people, enjoy playing slots from their homes or out on the go.

The introduction of mobile slot games has allowed us to play the best slot games from anywhere and on the device of our choosing. We talk more about the mobile aspect of slots in our article, going into more detail.

Return To Player (RTP) percentages are a crucial point that many individuals ignore when looking at playing some online slots. Such numbers are much higher online than in most casinos, providing the player with a much better win rate.

Most slots have an RTP of between 93 to 98% to bring this into some sense. The majority of games you find in Highstreet bookmakers like Ladbrokes or casinos such as Grosvenor that you play would have around 90% RTP. You can find the number can go down to 80% on some games, which is very low in comparison to online slots, which are almost always above 90%. Our recommendation would be to always play slots online as the RTP rate is higher than visiting physical locations.

New slots are released weekly with gaming providers as the market has grown yearly, so you can always expect new slot games to try out at your favourite online slots site.

Online Slots Bonuses and Free Spins

The biggest draw some UK online slot sites have with players can be the welcome bonus on offer or free spins no deposit offers. Almost all casino sites and slots sites you find online will have something for you as a new player to choose from when you sign up. The industry has grown so much over the years that we now have thousands of games to choose from when playing slots online.

Each slot site will usually offer a different bonus to try to entice you to play the available games. Some slot sites fall under the same parent company so you will find offers can be similar or sometimes identical. The wagering requirement for free spins or slots bonuses will vary from site to site, so checking the terms before getting locked into any new welcome offers is always good.

You can find some sites in the UK offering no wagering welcome offers, such as Sky Vegas, Betfair, Paddy Power and Pokerstars Casino. As mentioned above, you can find parent companies can influence the welcome offers and with all of these sites being related, you find a similar welcome offer. This is great if you want to withdraw your bonus winnings straight away without any wagering.

More often than not, bonuses or free spins at casinos or slot sites will require some wagering before any funds can be withdrawn when claiming welcome bonuses. There is never any free money at online casinos, although you can sometimes get no deposit bonuses at some sites; yet again, this will still require wagering before cash can be withdrawn.

If you decide to take up the welcome offer from the casino, wagering requirements will be required as mentioned above, and these can range quite a bit from casino to casino with as little as x10 to x65 on the Jumpman Gaming slots sites.

As an example of wagering, if you made the first deposit of £100 at your new casino and gave you a £100 bonus with x10 wagering, you would need to wager the bonus to £1000 before with can be withdrawn as cash.

When wagering your bonus, not all online gambling games contribute the same amount to wagering, so Blackjack would not contribute as much as playing slots, which usually comes with a 100% contribution rate. Some online casinos and slots sites will have excluded slots due to the high RTP, so always worth checking in the terms which slots are eligible to be used.

Welcome offers or free slots no deposit bonuses will often come with a time limit required to wager the bonus before it is removed from your account, so always check the timescale involved when wagering a bonus. With some casinos, this will vary from site to site, which can be as little as 48 hours to 30 days.

When claiming welcome offers in the free spins format, these are generally allocated to a particular slot game only so much easier to understand what’s required; it’s a case of checking the wagering requirements and timescale given to complete it.

You can also find limits of the stake size or maximum win when it comes to both casino bonuses and free spins; this is also a term to check out, as you might hit a big win to find out it’s over the maximum win limit or when using a stake size too high the casino may remove the bonus from your account.

Mobile Online Slots UK Players

Over the years, we have all moved more towards mobile for most of our internet-based needs and so have the online casino games providers, with all games now being made for mobile first and then adapted to fit the browser-based casinos. With this being the way mobile casino games have been designed, you will not notice much difference when playing on your laptop or PC from playing the online slots sites on your mobile phone or tablet.

With the huge range of games across various casino sites, these are designed for mobile platforms and browser-based systems. This means that various games can be accessed across lots of different devices, including iOS, Android, Windows, and other mobile devices.

When it comes to getting stuck into playing mobile slots sites, you have a couple of options available at Online Slot Sites; you can use a dedicated mobile app if they offer one, which can usually be downloaded directly from the site or the app store and the other option is to play directly on your mobile browser. We have found both options to be great, so this is a user preference.

Recommended Slot Sites with Low Wagering Requirements

As mentioned above, casino bonuses come with various wagering requirements, and some are very high, so it’s always the best option to find a welcome offer with lower requirements so you can have a good chance at withdrawing the cash!

Before you start on a new welcome bonus, it’s always recommended to work out how you will complete the wagering requirements given by the casino. Most often, you will have at least 30 days to complete this, which gives the player lots of time, but you could run out of time in the cases of shorter timescales.

If you are brand new to online slots sites, we would recommend going for the lower wagering casinos to give you a better chance of wagering in time and converting your bonus of free spins into cash. 

100% Up To £100 Bonus
Claim Offer

Terms and Conditions

Welcome bonus for new players only | Maximum bonus is 100% up to £100 | Min. deposit is £20 | No max cash out | Wagering is 35x bonus | Maximum bet with an active bonus is £5 | Eligibility is restricted for suspected abuse | Cashback is cash with no restrictions | Skrill & Neteller deposits excluded | Cashback applies to deposits where no bonus is included | T&C’s apply

It’s best to plan when taking on a new bonus as to what game and how long it will take roughly to complete the wagering. On lower stakes, such as 10p or 25p, having to wager £1000 might take a very long time, so make sure you have enough time to tackle the task.

The more risky players who take on bigger spins might not have the same issue, but this will certainly take more time on lower stakes, so proceed with caution.

If you can find a casino with a 30 days timeframe to wager the welcome bonus, this is the best case as it will provide more than enough time to get wagering done plus you always have the option of auto spin if you don’t mind leaving the slot to run on autoplay.

The wagering amount is the main thing to check on your bonus, with the lower amount being, the better, but around 30 times is a reasonable figure online at the moment, but there are options for lower amounts such as 10 or 20 times. Another big thing to check on the wagering required is if it includes your deposit and welcome bonus as this will double the amount required; ideally, you want wagering requirements on the bonus only.

Lastly, check which games you can use to wager the bonus as, more often than not, some games are excluded, which are mostly table games due to the very high RTP involved, but slots we have found are 100% in most cases.

Play Free Slots Online

Most game developers have free games that you can try before depositing real cash but they will require you to verify your age before playing when accessing from the UK. This can give you a feel for how the games perform and any features you may like or not like before playing for real. This is a great choice for new slots players to get accustomed to how the games function and navigate each slot game’s interface.

Unfortunately for UK players, this has been banned by the UK Gambling Commission on online casinos, but you can still find demo games on 3rd party websites or visit the game developers directly. Anyone outside the region may still find places to try slot games for free. The UKGC found this to be an issue amongst problem gamblers, so it was removed from all the licensed UK online casinos and slots sites.

We have found websites that are not actual casinos may still offer the chance to try out free demo slots, but verification will be required before trying them. No licensed casino should be promoting the chance to play free slots.

For all the players outside of the UK, you could have the opportunity to try free slots games at your favourite online casino, so worth checking if they have that option, as it’s great to try before you buy!

High Payout Slot Sites

Almost all online slot sites or online casinos will have a big enough variety of slots to find the higher payout games. When looking at your selection of slot you want to play, the best thing to look at is the payout for that game, often referred to as RTP on most casino sites, which translates to Return To Player. This is the expected return to player for the money played on the slot game so as an example, if the slot you are playing has a 95% RTP you would expect 95p back for every pound wagered.

The RTP is based on an enormous sample size over thousands of spins which will conclude the percentage figure. However, this doesn’t consider the volatility of the slot or variance as it’s most commonly referred to. So with the slot having its RTP figure, it will also come with a high, medium, or low variance, which relates to the chance of winning per spin.

Some slots may return money to the player on nearly every spin, and others may have zero return for 50 spins, then a big win that would equate to the same slot that returns money frequently, bringing the RTP to a similar percentage. Still, they would rank very differently on the variance scale.

So players who prefer higher variance slots are looking for the big wins, which are often found at the slots with the larger multipliers versus the low variance slots, which also are popular among players when it comes to things like wagering bonuses.

For the player looking for the best payouts, it would make sense to go after the highest RTP slots as this will return more over the long run compared with the lower RTP slots, but we need to consider the variance when making a decision; otherwise, nobody would play the games if they got nearly all their money back on every spin with no real big wins.

The RTP varies from around 92% up to 99% in some cases, with the higher figure going to return more to the player over 1000 spins, but more often than not, the very high RTP slots have very low variance, which means the high payouts don’t really happen often. For the players looking to hit the bigger slot wins and more risk-averse, we would recommend checking the max multiplier as this is usually a good indication if the slot game can pay big, but it will come with high variance.

With some online slots, mixing up the RTP and variance is possible by choosing the stakes or the number of paylines you would like to use on that particular slot.

You will find most of the super-high jackpots games are low in RTP; such as Mega Moolah, but as a trade-off, there is the chance that the game can payout into the tens of millions if you hit the jackpot, so low RTP slots aren’t always to be avoided it depends on your goals when playing the slots.

If you wanted to wager a new welcome bonus that may take thousands of spins, it would make sense to go towards the really high RTP slots where the bonus should return very well over the bonus’s wagering. Therefore, we have noted some of the highest RTP slots below for players to try out.

  • Goblin’s Cave – 99.32% RTP
  • Ugga Bugga – 99.07% RTP
  • Mega Joker – 99% RTP
  • Jackpot 6000 – 98.90%  RTP
  • Blood Suckers – 98% RTP

Starburst

First up, we have the most popular slot game in the UK, Starburst. When you visit most online casinos, you will find Starburst on the homepage and be involved with any welcome bonuses, or free spins offer. This game is a great place to start for anyone new to online slots; with its easy to use interface and a 96.08% RTP, you can see how this is so popular.

Rainbow Riches

This game holds a bit of a legendary status among the slot community and has been around for years online and in betting shop machines. Rainbow Riches from Barcrest Slots runs at a modest 95% RTP which isn’t high but isn’t low; it offers an x500 jackpot when hitting its bonus round, among other bonus rounds, that brings players back every week. 

Bonanza Megaways

Bonanza is a bit different from the others above with its megaways element giving players the chance to win an incredible x10,000 stake. This game from Big Time Gaming has been a huge hit with everyone over the past 5 or so years. It comes with a 96% RTP and the opportunity to win huge amounts hitting the right combinations, many of which can be found on Youtube when looking for big slots wins.

Book of Dead

This game from Play’n Go has been a huge hit over the years, much like Bonanza with its opportunity to hit the big multipliers on the bonus rounds. Book of Dead is pretty simple to understand and play compared with others with only 1 bonus round available, but this is what brings the players to this game. It comes with an RTP of 94.25%, which a bit on the lower end, although you can win x5000 your stake, so higher risk, higher reward on this game.

Gonzo’s Quest

This game from Netent has taken the industry by storm and has really become a favourite amongst all the slots players. It has its own unique style and bonus rounds for players, including the potential to win x3750 times your stake at Gonzo. This slot has an RTP of 95.97%, which we think is very reasonable.

Mega Moolah

After talking about the enormous winners it’s seen over the years, we couldn’t leave Mega Moolah off the list, all going into the millions of pounds. This slot isn’t very flashy and offers a 94% RTP which isn’t the highest, but if you could be the next millionaire on this slot game.

Jackpot Giant

Much like Mega Moolah, this game has seen some massive jackpots win, with it having the second biggest jackpot ever won on this game at over £10 million. Again it’s not flashy and pretty basic, but with the opportunity of life-changing sums of money, then it’s worth a mention when looking at somewhere to play.

Break Da Bank 

This slot game is a classic slot with few features available for players, but it’s a huge hit with the players who enjoy this setup. Break Da Bank allows the high rollers to go up to a huge £125 stake on this game! This slot from Microgaming comes with an average RTP of just under 95%

Mega Joker

Mega Joker is another classic slot much like Break da Bank and has only 3 reels, so very easy to follow. This slot game makes a list and is so popular among players because of the super high RTP of 99%, which is arguably the highest of any game available. This slot game is a must-try slot for the less risky players.

The Demon Code

This newer slot game from Nextgen allows players to win huge amounts on the multipliers. Demon Code has  6 reels and 25+ symbols involved per spin. This game comes with a 96.26% RTP, and players can win x12500 times their stake, one of the highest we have seen.

South Park

South Park is one of the original branded slots made by Netent and is still considered one of the most popular slots made by this software company. This game comes with 6 different bonuses available, including different features, free spins, and much more. It has a 96.7% RTP which is up there in the higher percentages on this list.

Monopoly Megaways

Here we have another popular branded slot from the household board game everyone loves Monopoly. This slot offers a great classic feel with an interactive Monopoly board, a must-play for the original game fans. The RTP is around 96.5% for this game which we think is pretty good and players will enjoy.

Razor Shark

A new game from a relatively new developer in Push Gaming, Razor Shark, looks at where online slots might be heading. The game allows you to adjust pay lines and win huge sums of money from the standard game.

Online Slot Games Variations

Slot games come in many variations and have branched off into different categories over the years. With all the different types of slots available for you to choose from, it’s good to understand which might best suit your style of play, ranging from big jackpot-type games or the more branded type slots with your favourite movie characters.

Best UK Branded Slots

Today, branded slots are some of the most popular online games. These games are connected to movies, reality shows, game shows, sports teams, and every other brand you might think about. This type of game has been a huge hit with slots site players over the years as they often have some really unique and interesting features.

Branded titles are a bit more refined than the typical video slot, you can find. There are a few explanations for this.

The first is that considering that branded slots have the financial resources of a famous brand behind them, the budget is always much higher than a regular slot game. This means that innovations can be encouraged, and more slots games can be made.

Deposit & Stake £10 Get £50

Terms and Conditions

Deposit and stake £10 on eligible Casino games to get a £50 bonus. Wager the bonus 40 times on eligible games to make the bonus balance withdrawable. Time limits, game restrictions and T&Cs apply.

Lastly, branded games need to be very high standard as they are connected with the movie, TV show, etc. If any non-branded games have a poor setup and the players don’t like them, then it’s very much forgotten about, versus if the game is branded like Avengers and plays poorly, the slots player will then devalue the brand they didn’t like the game.

The most popular games include Ted, The Simpsons, Avengers, Superman, Batman, Scarface, Jumanji, and Jimi Hendrix Online Slot. Various software providers may develop these games to all play very differently and have various bonuses or features unique to that game.

Best Online Casino Video Slots

Video slots are the most popular online slots section, with those games always being the most played around casinos and slots sites. When visiting your favourite casino or slots site, you will find the games selection is mostly video slots.

These games also come with a wide range of features like paylines, bonus rounds for slots, side games, fantastic graphics, and even mini-games built within the game itself. The software developers took the traditional slot game and upgraded it with modern technology making it a much more exciting experience.

In terms of RTP and variation, games can differ, which often draws players towards a particular game versus choosing others depending on the risk and reward style they like to play.

The most popular video slots games include Gonzo’s Quest, Starburst, Dead or Alive, and Twin Spin.

Jackpot Slots

The jackpot slots allow players to win the biggest prizes, which can range into the millions. This is where, from just a quick spin of the wheel, you can win life-changing amounts of money, as we have seen in the past. As a consequence, they are also up there as the most popular type of online slot game.

There are two types of jackpot slot games: progressive and standard jackpot games; we explain these more below.

Standard Jackpot

Your standard jackpot game is usually hosted by either the casino or the software provider. They set up a jackpot for that game, which will be triggered when the player hits the winning symbols or bonus. When the jackpot is won, it is reset and added back into the game until another player wins the grand prize.

Progressive Jackpot

The progressive jackpot slot works differently from the standard jackpot as the prize money keeps rising as more players keep playing the game. This is what makes progressive slots such a huge favourite. When a player takes a spin on the progressive jackpot game, a small amount of the sum wagered with be contributed to the total jackpot figure. The amount taken from the stake towards the main jackpot prize will vary from game to game, but it works very much like the lottery as the more players play, it will keep rising daily.

The progressive jackpot games offer the largest amounts to be won due to the software provider being in control of the jackpot itself from the player’s stakes they have wagered and the casino itself not putting the jackpot money up for grabs. This also allows the jackpot to spread across multiple slots sites or casinos by the same game as it’s connected across all platforms; this is how the jackpots get to such a high amount with 1000’s of potential players playing across multiple platforms sites.

Mega Moolah Winners. The biggest jackpot win was on the Mega Moolah slot game was £13.2 million by soldier Jon Heywood back in 2015, with many more huge winners on this game. You can check out all the many winners on Mega Moolah over their website with the dates and amounts won here. 

The most popular jackpot games include Mega Moolah, Major Millions Mega Fortune, and Arabian Nights.

Online Casino Classic Slots

The classic slots games are what some people might remember from years ago with a much more simple design. The slot machine games don’t offer the same features as the more modern slot games as the classic games come with fewer paylines, often no bonus rounds available, and fewer winning combinations up for grabs.

The classic slots might not suit everyone, but they bring a simplified way of playing without as many flashy components involved and are easier to follow. More often than not, the classic slots game can offer a higher RTP than the modern games, possibly due to the game’s simplicity.

Super Nudge 6000, Break Da Bank, Double Whammy, and Couch Potato are the most popular games.

UK Online Slot Sites Software

With the mention of the different slots site software providers in this article, we should explain a bit more about them. When you visit an online casino or slots site, you will find that almost all games are from a 3rd party casino software provider who creates the various games players love to play.

As you can imagine using a 3rd part software company makes things much easier for the casino or slots site itself as they don’t have to try to develop the games themselves or have any of the maintenance required to keep the games running the way they should. Developing games can be costly, with very few casinos making their own slot games. 

This has become a very competitive marketplace between developers as everyone is looking for the next big hit. With competition comes great advancement in the industry, with games constantly being made better year after year.

Some software providers are top-rated, so you will see quite a lot when visiting your favourite casino or slots site, which we will go into more detail below.

NetEnt

Netent is a software provider that started in Sweden back in 1996. They have been a leading slot game industry developer for many years now, with some huge hit titles in the top 5 most played games across all online casinos.

The two big games from Netent are Starburst and Gonzos quest which made our list of the top slots sites games to play. These games lead the way for Netent but offer some other fantastic games to try out with big win opportunities.

Microgaming

Microgaming is possibly the largest software provider on the market with a huge catalogue of games and can be found at nearly online casino or slots site on the internet. They offer a great range of different games, from the more branded slots to classic slots.

Microgaming offers some great slots, including the hugely popular Mega Moolah with its gigantic jackpot wins over the years. The branded games have been a big hit for Microgaming with contracts with popular TV shows and movies such as  Jurassic Park, Game of Thrones and Hitman. Some of the original games they have made over the years have also become a brand of their own among the gaming community, including Immortal Romance, Thunderstruck and Avalon.

PlayTech

Playtech was founded in Estonia has been around since 1999, and another of the bigger companies involved in this industry with around 5000 staff working for this software developer. 

Playtech is certainly one of the best software providers on the market and looks after the Virtue Fusion software, which many popular bingo sites use to power their sites. Playtech is very involved in the branded side of the slots business with titles including The Dark Knight, Justice League, and the classic Frankie Dettori’s Magic Seven.

Yggdrasil Gaming

Yggdrasil is very much one of the newer developers on the scene, having only been around since 2013, but this provider has done extremely well since joining the scene with many great titles under their belt.

They might not get as much attention as the bigger software companies as they don’t have the same variety or branded titles. Still, the offering from Yggdrasil is outstanding and unique to other companies. Slots such as Vikings Go Berserk, Vikings Go Wild, and Blood Moon Wilds are the most popular games from this brand.

Play’N Go

Play’N Go is another Swedish brand in the industry that started the business back in 2007. They have built up a great collection of games, with many being hits across online casino sites, usually offering great RTP.

The most popular games from Play’N Go would be Book of Dead, as mentioned in our best slots list and Moon Princess, Reactoonz amongst others. These games often have a great opportunity for some big wins, plus the nicely done graphics keep the players returning.

Novomatic

Novomatic has been around the longest out of all the software providers, with this company dating all the way back to 1980. This casino software developer doesn’t only operate online; they have a huge list of land-based casino clients who run the Novomatic games, so next time you are in your local casino or out in Vegas, keep an eye out for the Novomatic slot machines!

The most popular of all the Novomatic games are Book of Ra, which is very similar to Book of Dead from Play’N Go with the same bonus feature, but they do have others worth checking out, such as  Lord of the Ocean Dolphin’s Perl and Sizzling Hot.

Best Slot Site Payment Methods

Online slot sites have changed a lot over the years, giving us many more options to deposit and withdraw money which is great with e-wallets that have become really popular. These are often much faster in withdrawing money than bank accounts or debit cards.

Nearly all online casinos or slot sites now offer many different payment forms, including debit cards such as Visa or Mastercard, plus online options like PayPal, Apple Pay, Skrill, or Neteller. Some sites even let you play using your mobile phone bill. Credit cards are no longer allowed for gambling purposes as per the UK Gambling Commission so take note of that before trying a credit card to make a deposit.

Most players will have their preferred payment method when playing slots online. Still, not all casinos will accept all of the different methods we have mentioned, so always good to check what is accepted for players who prefer online methods. We have found PayPal is accepted at nearly all online casinos now, but others, such as Skrill or Neteller, may not be.

Another consideration is whether any fees apply when using particular payment methods. Using these may cost you money versus sticking to a bank transfer or debit card.

Debit cards are the most common method amongst players, as nearly everyone will have one that comes with having a bank account. With Visa, Mastercard, and Maestro being what we see most often in the UK, this may differ if you are in other countries.

Nearly every online slots site or casino will accept this as a payment method unless specifically set up for something like cryptocurrency. Deposits are always very quick with bank cards with money instantly credited to the account, but withdrawals can take 1 to 5 working days to land back in your bank account.

As mentioned above, when looking at Ewallets, we have quite a few different options ranging from PayPal, Neteller, EntroPay, Skrill, Neteller, and more. These methods are credited instantly, much like debit cards but also see a much faster withdrawal time with money landing back in your wallet within 24 hours in most cases. 

Bank transfer is not often used as a payment method anymore because it is quite slow. Still, it will be used with nearly all online casinos accepting this as a valid payment method for substantial deposits and withdrawals.

We have also seen a rise in slot sites accepting such payment methods as Apple Pay, Google Pay, Prepaid cards, and popular Bitcoin. Bitcoin is not often used in your popular UKGC casino sites, but casinos are now dedicated to using cryptocurrency.

Online Slots Tournaments

Slots Tournaments have become an exciting new feature among many online casinos, with many different prizes on offer for winners. Prizes can be won for the top 100 players, varying from free spins and bonuses to cash prizes.

With the opportunity of many players winning something, you will find these can be quite popular as everyone battles it out to win the grand prize! Tournaments may vary between different casinos, but most often, players will accumulate points from wagering on a particular slot game with the highest number of tournament points at the end, collecting the big prize.

18+. New Casino players only. Deposit required. Min bet 10 on qualifying games. 40x wager reqs (bonus only) on selected games. 30 Bonus + 30 Free Spins for a selected game. Accept within 14 days.

The Tournaments will come with a timescale in which the points must be accumulated and come with a buy-in to enter the competition. So this can require quite a bit of luck to win after you have bought in as you need to try to win as much cash as possible to accumulate points and move up the leaderboard.

Some casino sites may offer free entries to certain tournaments so you can join in the fun without having to put down any buy-in cash!

Prizes vary between casino sites and tournaments, but a cash prize for the top places is the most common, with free spins or bonuses given to the other players, some of which are won during the tournament itself. This can be great fun for the big slots fans and there are some great rewards there to be won, but as with most things casino related, luck and a good strategy are required!
