Who We Are: All Slot Sites - Our Mission
What is a slot site?
A slot site is any website (usually an online casino) that offers real money slot games to gamblers.
There are lots of free to play slots, many available on social media platforms like Facebook, but we do not concern ourselves with those. We just focus on the games on which you can stake money for the chance to win prizes. Our listings include bingo sites and sportsbooks that offer real play slots games too.
Who we are
Allslotsites.com is an independent information resource for slots fans who want to find casinos where they can enjoy their favourite games in a safe, fair and secure environment.
What we do
We review and rate slot sites to help you to find one that will suit your preferences. We make it easier for you to search out a suitable site by categorising by operator, games, payment services, bonuses and other criteria. Our reviews are based on research and live testing with real money to give you a genuine and accurate assessment of the experience. Find out more about how we test and review in this article.
We also publish reviews of slot games every week so you are up to date with all the latest game releases from top game providers. You will also find news and useful consumer guides for online slots players in the UK. Our aim is to provide you with everything you could possibly need to know to be entertained whilst also staying safe.
How we make money
We are an affiliate business. That means we are paid commissions for every customer that we refer to the partner sites in our listings. There is no cost for you to use our site and on some occasions you may pick up an exclusive bonus provided to us by one of our partners. The commission fees do not impact what we say in our reviews but they may affect where a site appears in our lists.
Why you can trust us
Every word published on our site has been written by an experienced industry professional or a regular slots player. This allows us to meet the high standards we set for ourselves in providing information and opinions that you can trust. We hope that after using our site you will agree.
You can read about our site editor here.
How Do I Pick The Right Slot Site?
There are 1000s of slot sites for you to pick from. 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? Here are some key points to look out for when making your choice.
Check The Site Has a UK License
You should only play at casinos that display a license number issued by the UK Gambling Commission in the footer of every page on their website. We publish licensing information in our reviews with links to relevant pages on the Gambling Commission website.
Check the Terms of the Welcome Bonus
Each welcome bonus is configured differently. Look out for the minimum deposit, wagering requirements, games that you can use your spins on and the maximum cash outs. Don’t claim a bonus without understanding what you are getting first.
Find Out Which Games Are Available
Each site has a different mix of game suppliers and different range of slots. Check our reviews to find out which games you can play at each site before you sign up. If you have a favourite slot studio, check our profile pages to find out which casinos their games appear on.
Research Reputation and Customer Reviews
Read our reviews which tell you how casinos score on popular consumer review sites like Trust Pilot. We also research the license of each casino to tell you whether an operator has any history of regulatory action against them by the Gambling Commission.
Check Available Payment Options
If you have a preferred payment service, like Paypal, be sure it is accepted at your site. Also check minimum deposit and withdrawals values and expected withdrawal processing times. It’s always good to play at a site with fast withdrawals.
Check The Site Has a UK License
Every slot site should prioritise the safety of its customers. Responsible gambling tools are mandatory now at all UK slot sites, allowing players to set limits on their deposits, wagering, losses and play time.
How Do I Register?
Before you can play at any slot site in the UK you will need to register an account. This requires you to share some personal information that the operator will use to verify your ID and age. This is how to register:
- Click the Sign Up or Register button on the home page of you chosen site
- Then enter your personal details when prompted.
- You will need to provide at least your full name, date of birth, home address, mobile number.
- Choose a username and password
- Hit the button to submit your details and wait
- As long as your details are correct, you will be registered and ready to play in just a few seconds
Why do I need to provide all this personal information just to play a slot game?
In the UK online gambling is regulated. Only people over the age of 18 are allowed to play slots at an online casino, even in free play mode. Therefore, the operator must verify your age and ID before they can allow you to play. This process is known as KYC (Know Your Customer) and it is common practice in a number of UK industries.
Which Welcome Bonus Is Right For Me?
Welcome bonuses are a big part of deciding which slot site to play at. Make sure you understand the key terms of the offer before you accept it. Here are the important ones to look out for.
- Bonus Triggers – look for the minimum deposit required to release the bonus. Usually it will be around £10, but it may be higher and an insufficient deposit will mean you miss out. No deposit bonuses are a rarity now but you can find them from time to time.
- Maximum Bonus – the bonus will be capped, anywhere from £10 to £500, sometimes more. You will only be credited up to the maximum.
- Wagering Requirements (WR) – check how much you have to wager to release the bonus and any winnings you generate to your real money balance. The WR is usually around 35x but can be much higher. Lower WR mean better value bonus and more chance of walking away with some cash. You can find out more in our guide to Wagering Requirements.
- Game Restrictions – some bonuses are only available on specific games. This is particularly true of free spins. Check to see which slots you can play your bonus on.
- Maximum Cashout – how much will the operator let you take home with you when using your bonus funds? Often your winnings will be capped at £100 or less. Don’t get caught out by this one!
- Expiry Times – always make sure you are aware of how long you have to claim the bonus from registration, and how long you have to use it once it is credited, or you may miss out on some free spins! Bonuses and free spins are removed after expiry is reached.
- Validity of Payment Options – not all payment options will be valid for every bonus. Often eWallets like Neteller and Skrill are excluded and deposits with these services receive no bonus.
In short, ALWAYS check the terms of an offer before you sign up and deposit so that you know what you are getting into.

What Games Can I Play at UK Slot Sites?
There are easily more than 10,000 online slots in existence and available to play at slot sites currently operating in the UK. And many more games are being produced every year. So there is shortage of choice! As a starting point, here are six of the main categories of slot and one game we recommend that you try from each. We've also recommended a UK slot site from our favourites where you can play these games.
These are the most popular type of game at an online casino. Most have 5 or 6 reels with 3 or 4 rows of different symbols. Lining up identical symbols across pre-defined paylines triggers a win. 1,000s of these games are produced every year. Popular providers include Nolimit City and Relax Gaming.
The Megaways™ slot engine, designed by Big Time Gaming, is an ingenious variation on the classic video slot. Each reel displays a variable number of symbols after each spin, usually between two and seven. This creates a variable number of paylines, as many as 117,649 in some Megaways™ games.
Progressive Jackpots have the biggest prizes, sometimes in the millions of pounds. From every £1 wagered on a progressive slot, a small percentage goes towards the progressive prize pool which keeps growing until one lucky player triggers the payout.
Cluster Pays Slots
These games use a different payout model. Instead of lining up symbols in rows across the reels, players must land them in clusters adjoined vertically, horizontally or diagonally. This format is often combined with Avalanche Wins and Progressive Multipliers.
Free to Play Slots
If you want to play slots for free you still can still do so at most UK casinos. Under UK law you will still have to verify your ID and age by registering an account. Usually that is enough, but sometimes further documentation is needed.
Real Money Slots
All the games at the casinos listed on our site 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. Check out our guides on slot variance and RTP below to find out more about how real money slots pay out.

Which Is The Right Deposit Option For Me?
If you want to play slots for real then you will need to make a deposit. Most casinos support several different payment services and you will need to choose which one to use. You can pick from debit cards, eWallets, electronic transfer providers, mobile payments and pre-paid cards. Each has its own pros and cons. Here are some things to think about when choosing how to make your deposits.
For more information about each payment type, read our Payment Guides.
- Popularity – the most popular payment services will be accepted at every online casino. For example, you will always be able to deposit and play with a Visa or Mastercard debit card. Less popular services like Trustly or Google Pay aren’t always available. If you want to deposit with one of these services then you will have less casinos to choose from.
- Convenience – some services are easier to use than others. For example, once you have set up a Paypal account it is one of the easiest deposits services there is. You can deposit in seconds without sharing any bank details by just using your online username and password. Keep in mind though that you do have to register a Paypal account first which may take 5 to 10 minutes.
- Minimum Transactions – the minimum transaction levels for deposit and withdrawal will vary from one service to the next. Generally speaking, debit cards provide the best range of transaction levels, with some slot sites, like Casumo, even taking deposits as small as £5 from a Visa or Mastercard.
- Bonus eligibility – beware that some services are EXCLUDED from bonuses, including sign up offers. eWallets like Neteller and Skrill are the most common to be ineligible for these deals. Historically, anonymity with these payment options could be exploited to abuse the bonus systems at casinos and earn multiple sign-up bonuses for one person. So they were dropped in the terms and conditions. If you want a sign up deal we recommend avoiding Skrill and Neteller deposits.
- Withdrawal speeds – transactions are processed back to payment providers at different speeds. If fast withdrawals are your priority then keep this in mind. Typically, eWallets are the fastest. Once the casino has dealt with your request, payments to Paypal or Skrill are instantaneous. Some banks may take a few days to process the payment into your account. And some services – like Paysafecard – are not available for withdrawals at all.

Responsible Gambling And Online Slots
Online slots are popular because they are entertaining – they offer a fast hit of gambling fun, with each bet playing out in seconds. But overuse of the games can lead to addiction and you must take great care when playing to keep it fun.
Here are some useful tips to stay safe when gambling.
- Set your own limits – decide for yourself how much you wish to spend each month based on how much you can afford and stick to those limits. You can use responsible gambling tools in your account to help you set financial and time limits on your play.
- Don’t chase your losses – if you have a session when it seems like every spin is a losing one then take a break. Don’t get into a phase of chasing your losses – trying to win back your money. It can lead to much bigger losses and more frustration.
- Avoid emotional gambling – the phrase, ‘don’t gamble without sound judgement’ is pertinent here. Don’t start placing bets when feeling down, frustrated or under the influence of alcohol. You won’t make good decisions.
- Don’t bet on games you don’t understand – slots come in all shapes and sizes and with many features. Make sure you understand the size and nature of your bet, including the number of paylines you are betting on which affect the size of your bet. The same goes for live dealer tables with more complex rules about stakes and side bets.
- If you think you need help, then look for it – there are many charities that help with problem gambling like those listed below. It is always better to share the problem and seek advice.
Problem Gambling Charities
Here are five problem gambling charities that can help with addiction.
- Gamblers Anonymous – group support for those with problem gambling.
- Gamcare – independent UK charity supporting those with addiction.
- Gambleaware – independent charity commissioning prevention and treatment in the UK.

Licensing for UK Slot Sites
You must make sure that any online casino you choose to play at is fully licensed by the UK Gambling Commission. Every casino in the All Slot Sites listings 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.

No, slot sites and slot games are not rigged. They use software in which the outcome of every reel spin is generated randomly by an algorithm so it cannot be fixed. The games at sites licensed by the UK Gambling Commission are always fully audited and tested to ensure that the games run in this way. Never play at sites without a UK license as you cannot be sure that they are fair. At AllSlotSites.com we only review UK GC-licensed sites.

To find slot sites with good odds you need to look for slot games with a high Return to Player (RTP). The RTP refers to the amount of money paid out in prizes measured as a percentage of all the money wagered on a game. In short, a high RTP slot will give you better odds. Typically, slots have RTP of around 96% but you can find games with RTP as high as 98%. Check this guide to find games with high RTP.
