A Guide To All Slot Sites
There are 1000s of online slot sites for gamblers to pick from today. With hundreds of new games arriving each month and new casinos cropping up all the time, we are spoilt for choice.
So how do you decide where to play next?
Well, each of us will have different priorities when choosing a site, though for most of us the free spins and bonus package for new players will be pretty high up on the list. If you are a seasoned player then you will probably have a favourite game too, or even a favourite game provider that you look out for. If you are new to the reels then you will probably be searching out simple, straight-forward, low-risk slots that deliver regular payouts. Of course, whatever your choice you should always make sure you gamble at a site that is fully regulated by the UK Gambling Commission, provides a safe and secure cashier, and offers a professional support service to help with any queries or complaints you may have.
So it’s clear that there are a few considerations to bear in mind when choosing your next slots adventure. That’s why we have put together the following guide to help you find the right casino from our list.
When you join any new casino you will be offered a welcome package, usually consisting of free spins and deposit bonuses. These offers are an incentive for you to join and also an opportunity to test drive the site, get a feel for the cashier and the game selection, and decide if you want to continue playing there. If you are a regular casino player then you will probably know that not all bonuses are the same. They come in all different shapes and sizes, with varying wagering requirements and withdrawal restrictions attached, and you should always check these out in the significant terms and conditions before signing up and depositing.
Here are five points to look out for in your bonus offer.
Always see how much you need to deposit before you can claim the bonus. The minimum deposit is usually £10 but it can be as high as £25 in some offers on our site. Don’t get caught out or you’ll be calling customer support for your money back! It is still possible to pick up no deposit slots bonuses too, dished out free on registration. In these cases, you will need to verify your identity with the casino you play at first. Check further down this page for the latest no deposit offers.
If you are planning on funding big with your first deposit then make sure you check to see the maximum bonus you will be eligible for. If the top limit is £100, you won’t get any more no matter how much you put down.
Almost all bonuses come with wagering requirements. This is the amount you must wager before the bonus itself, and any winnings generated, become withdrawable cash. The multiplier is usually around 30x but can be much higher. Just note that the higher the multiplier, the less chance you have of walking away with some cash in your pocket. Check our list of slot sites with low wagering requirements on this page for the current best value promotions.
There will also normally be a limit to how much you can win with your bonus funds. This applies to free spins as well. Anything from £100 up to £500 is a typical limit. If you go over, any excess will be forfeited when you go to withdraw.
Casino operators like to put an expiry date on their bonuses. If you don’t use the spins or bonus funds before the specified date then they will be forfeited. Don’t make that mistake – they are free and there to be enjoyed.
Best No Deposit Slot Sites
Though no deposit bonuses are rare, it is still possible to pick them up when operators are feeling generous. Check the wagering requirements on any winnings as they are not likely to be immediately withdrawable. Also look to see how much you can win with your free spins, the payouts will normally be capped at between £20 and £100. But hey, these are free, no deposit bonus spins, so who’s going to be picky?!
Best Slots Sites With No Wagering Requirements
The best value bonuses and free spins come with NO wagering requirements. That means you can withdraw winnings from bonus or free spins wagering in cash directly! No questions asked! As you can see, this kind of offer is EXTREMELY rare. In fact, right now in the UK we only know of two casinos where this offer is available – our favourite of which is Skill on Net’s Play OJO. This is a great destination for slots play and they have built a reputation on providing what they call the fairest casino promotions online. We’ll let you decide if you agree.
Best Slot Sites With Low Wagering Requirements
Not all bonuses can be free of wagering requirements. However, some will have a lower requirement than others. Typically in the UK wagering requirements for a casino bonus will be 30x the value of the bonus (and sometimes the deposit). That means the player must stake money to this value before the bonus, and any winnings, become withdrawable in cash. Typically our bonuses with low wagering requirements start at 20x the value of the bonus. That means you have more chance of walking away with some cash in your pocket after you’ve enjoyed your free spins.
Slot Games and Software Providers
The 6 Different Types of Slot Game
Here we’ve broken down all the video slots currently available at UK casinos into six categories. Pretty much any game you play can be put into one of these groups.
These are the most popular type of game at an online casino and the ones you are most likely to play. The average video slot will have a reel set of 5 or 6 reels, each with 3 or 4 rows of symbols. Some will take their inspiration from classic fruit machines, but most will draw on a wide range of interests – pretty much ANYTHING can be used as the theme for a slot game, which is what makes this type of gambling so fun. Prepare yourself for some pretty sensational graphics, animations and video too. Many of these games have Hollywood-level production values!
The Megaways™ slot engine has revolutionised this sector of the gambling industry. Here, each reel displays a random number of symbols after each spin, usually between two and seven. The more symbols displayed, the greater the number of paylines in play – as high as 117,649 in some games. Compare this to the typical video slot which might have just 10 or 20 paylines! Megaways™ creators, Big Time Gaming, have combined this game engine with incredibly high variance to create some of the most infamous high-risk slots of recent years.
These games are for the big jackpot chasers. Prizes in Progressive Slots can be in the millions of pounds, though of course the odds of winning are very low. You may have heard of titles like Mega Fortune from NetEnt, or Mega Moolah from Microgaming, which are famous for their life-changing prizes. You’ll usually find these games in a special area of a slot site with the prizes displayed in a ticker next to the logo.
If you want to dip into the retro corner of the market then classic slots could be for you. They will have a very basic design consisting of just 3 reels and they will use the symbols and imagery from old skool game machines – grapes, melons, lucky 7s and gold bars. These simple fruit machines are a great place to start. There are many developers still producing games like this every year. Play n Go’s own Sticky Joker is a good example.
If you want to play slots for free you still can at most slot sites listed here. In 2019 the rules around freeplay changed in the UK under direction of the UK Gambling Commission. You will first have to verify your ID and age with the gambling operator whose site you are playing at. That means registering your account and providing ID like a scan of your passport or driving license. If you have a small budget and want to play slots for real then you can still do that for very small stakes of as little as 1p or 5p at most casinos too.
Real Money Slots
All slots at the casinos listed here are available to play for real money. If you choose to play for real then have a think about how much money you want to spend before you start and set a stake value that you are comfortable with. Remember that a spin takes just a few seconds to complete so it is possible to spend your balance very quickly. Check out our guides on slot variance and RTP below to find out more about how real money slots pay out.
What Makes a Great Slot? Themes, Symbols, Features, and Gameplay
Themes and Sounds
Every slot game has a theme of its own. Some are very popular and crop up many times over – Ancient Egyptian titles like IGT’s Cleopatra or Novomatic’s Book of Ra are very popular, as are games based on Popular Movies or Rock n Roll bands. Others are more obscure with themes like Steampunk or Science Fiction. Whatever your taste there will be something for you – so if you’re going to spend some time with a game, make sure it’s one that looks good to you!
Every slot will have a mix of low value and premium symbols. Low value ones are typically card values 9 through to Ace or the suits, Spades, Clubs, Hearts and Diamonds. Premium symbols are always based on the game’s theme. For example, a common symbol in an Egyptian-themed slot would be the Scarab Beetle. In addition there are usually Wilds, which sub in for all other symbols in winning lines, and scatters, which are symbols needed to trigger the free spins round.
Features and Gameplay
Most slots will have additional features that kick in when special symbols land in the base game. Features are what elevate the gameplay beyond the standard spins. They give you more fun, more tension, and hopefully more chance of scoring bigger wins. Here are some examples of typical slot game features.
These are the most common feature in slots. Something like 5 or more free spins of the reels will play out, often with the opportunity to earn more by landing extra scatter symbols. Free Spins usually come with enhanced symbols like Multipliers or upgrades.
These are commonly added to symbols or whole reels. When the symbol forms part of a winline then the multiplier value, which can be as high as 15x or 20x, is applied to the payout. Game developers like Big Time Gaming have built amazing slots that combine the free spins and multipliers to sensational affect in games like White Rabbit and Bonanza.
Another slot feature that appears regularly, particularly in Megaways™ games, is Cascading Wins. In this instance, whenever a win occurs, all winning symbols are removed from the reels and new ones drop down in their place. This can create new wins, and further cascades. Check out NetEnt’s Gonzo’s Quest for a good example of a Cascading Wins slot.
Slot Game Return to Player (RTP)
The Return to Player (RTP) is the average amount that will be paid out as a percentage of the overall money wagered on a game over time. Most slots have an RTP of around 96% to 97%, though some will be lower and some will be higher, even getting closer to 99%. It’s important to remember that this is an average number, not an absolute statistic! Just because a game has an RTP of 95% doesn’t mean that it will always pay out £95 on every £100 wagered. That would be very boring, and pointless! No, this is the average – some of us will experience much better returns on our wagering, and some of us will experience much lower returns. However, it is a useful number to know, and if you are looking for better odds then you could try playing games with a higher than average RTP. Here are some of the best. Just click the image to play at one of our recommended slot sites.
5 Slot Games With High RTP
BLOODSUCKERS II BY NETENT (98%)
GOBLINS CAVE BY PLAYTECH ( 99.32%)
UGGA BUGGA BY PLAYTECH (99.07%)
MEGA JOKER BY NETENT (99%)
STARMANIA BY NEXTGEN (97.87%)
Slot Game Variance
The other significant slot feature to look at when choosing your game is the variance. This will tell you how volatile a game is, by which we mean, how far from the average return to player the payout may vary during your session. Low variance games will not drift far from the RTP so will pay out in small, regular amounts. These our considered to be low risk games. High variance games, considered to be high risk gambling, are those where the payouts will be well outside the normal RTP during your game play with long periods of dry spins with a very low RTP, followed up by short bursts of very high payouts. If you are new to slots, or if your budget is small, then high variance games are to be avoided because they can use up your funds very quickly with no return. If you are in for the high stakes, high drama of massive win sequences that come from games like Bonanza and Dead or Alive then high variance will be your thing and you should seek out these titles.

WHITE RABBIT BY BIG TIME GAMING
BOOK OF DEAD BY PLAY N GO

BONANZA BY BIG TIME GAMING
Slot Site Payment Options
After checking out the bonuses and the games on offer at your prospective casino you should also consider which payment options are available to you. You may choose to deposit with a debit card which all operators will facilitate. However, there are other options that you are available at most sites, and each one comes with its pros and cons. If you are interested in using an eWallet then Paypal is a good choice as it is accepted at many slot sites and offers fast and free deposits and withdrawals. Other eWallets, including Skrill and Neteller are also widely accepted and come with the same advantages, as well as allowing you to transact without directly sharing your bank details with the gambling operator, which for many is a more safe and secure method of payment. Elsewhere, mobile slots players may like the opportunity to deposit via their mobile phone using BOKU. This simple method has a daily limit of £30 and funds are added to your phone bill or removed from your current balance.
You can find out about each of these in our Slots Payment Guides.
You must make sure that any online casino you choose to play at is fully licensed by the UK Gambling Commission. Every casino listed on All Slot Sites has been issued with a license by this body. They are responsible for regulating the industry in the UK and ensuring that operators act responsibly to ensure vulnerable gamblers are not exploited, that their platforms are not used for criminal enterprise, and that the service they provide is safe, fair and fully audited. You will also find that almost all the sites in the UK are licensed in an international jurisdiction, by a body like the Malta Gaming Authority or the Gibraltar Gambling Control Commission. Operators like to base themselves in these territories because as well as offering online gambling operator licenses, they also provide favourable taxation laws. You can check the licensing status of any online casino in the footer of the website.
Gambling at a licensed casinos ensures that you are playing slots that have been audited to ensure the outcome of each spin is entirely random, and that in the event of a dispute over a game, or your account, you have recourse to a third party. But that is not all that is important. Licensed casinos are also required to provide vital Responsible Gambling features in your account to help you manage how much you spend per day, per week and per month, and to give you the option to exclude completely by having your account locked and your address removed from all marketing lists.
Problem Gambling is a high-profile issue in the UK right now. If you think that you may have a problem with the amount you are spending on gambling then you can find out more about where to get help on our Responsible Gambling page.
