Playzee has one of the largest gaming libraries around, so it's easy to see why they could feature on any of these lists. Cluster pay slots are a slot mechanic that is different from traditional slot games. They offer a new, innovative way for players to play slots which is why they're so appealing.
Bonuses and Promotions at UK Slot Sites
Casino bonuses and promotions offer new and existing players at UK slot sites many benefits. Aside from the obvious of being able to win real money without any funds coming out of your pocket, there are others. New players that are greeted with a welcome bonus, can use this to learn the ropes. That can be navigating your way around a new slot site or learning a new slot game. Seasoned slot players can use the funds to try out new strategies or learn news games they haven't played before.
Here are some of the most popular bonuses you can expect to find at a UK slot site.
No Deposit Bonuses
No deposit bonuses are like the holy grail of casino promotions and as such, they can be harder to come by. A no deposit bonus offers you funds to play with, without having to spend a penny yourself. You can often qualify for these bonuses by simply registering on a new platform.
Welcome Bonuses
Welcome bonuses are typically the most lucrative as they are often what entices a new player to a casino or slot site. As such, this is a highly competitive area of the casino industry, which is great news for you. Welcome bonuses come in various different forms from no deposit bonuses or matched deposit bonuses to free spins and free bets.
Free Spins Offers
Free spin promos are a lot more common, which means you can usually bag yourself a few quite frequently. They're often attached to welcome bonuses but existing players can also grab some too when slot sites run various promotions. This could be when a new slot game comes out and the casino wants to promote it by offering players free spins.
Loyalty Rewards and Cashback
Loyalty rewards are a great way for slot sites to retain players. And who doesn't want to be rewarded for simply playing the games you love? Loyalty rewards come in all shapes and sizes from VIP programs where the more you play, the higher up you progress and earn more benefits to loyalty points that can be traded in for cash prizes.
Casinos also sometimes reward players by offering cashback on their losses. This is generally over a specific period of either a week or a month and it's typically a percentage of around 10-20%.
The Best Slot Sites for Mobile Play
Mobile play is fast becoming the biggest area for casinos these days. This is caused by two main factors - firstly, almost everyone has a smartphone these days, which means slot sites can reach a larger audience. Secondly, in today's fast paced world, when time is of the essence, we don't always have the spare time to sit down, open up our laptops and enjoy a gaming session. With mobile phones we can play our favourite games within seconds and we can also do it on the go.
What to Look for in Mobile Slot Sites
The main thing to look for is to ensure the website is optimised for mobile play. You can do this by loading the website on your phone if the slot site doesn't have an app and testing various elements. Firstly, make sure you can do the simple things like login, deposit and withdraw and that the website is easy to navigate on the smaller screen.
Secondly and probably most importantly, ensure you can play your favourite games. You want the games to load to your full screen size and that there aren't parts of the game cut off. Make sure you test a few games as some casinos have some games that are optimised and some that aren't.

Slot Site Mechanics and Features
Slot game mechanics and features are a vital part of a slot game and often what separates one from another. Here, we will take a look at a few of the components to give you a better understanding of both.
How RNGs Work in Slot Sites
RNGs or random number generators are basically the mechanics that spin the reels and determine what they land on. They ensure that every spin is unique and that the slot game is fair. There is no way to alter a RNG, which means players can rest assured that they are not being cheated. RNGs are independently tested and certified if they meet fair gameplay requirements.
Understanding RTP and Volatility
RTP and volatility work in a similar way but they are different. The RTP (also known as Return to Player) is the amount a player is likely to win over a period of time. While, volatility is how often a slot game will pay out.
The RTP is determined over millions of spins so it can be quite hard to measure. However, an easy explanation would be, if you were playing a slot game with an RTP of 96%, ‘technically’ you would win £96 for every £100 wagered. We say technically as this is determined over many spins and not just £100's worth.
Volatility, also known as variance, refers to the frequency payout of a slot game. Low volatility slot games will pay out more frequently, however, the wins are typically small. A high volatility slot works the opposite way in that it will pay out less often but generally higher amounts.
Bonus Features at Slot Sites
Bonus features come in many different ways. Some developers like to have a certain style to their features and as such they often use the same bonus types. Some of the most popular include the following:
- Cascading Reels
- Expanding Symbols
- Free Spins
- Multipliers
- Scatter Symbols
- Wild Symbols
There are others but these are the most popular used by top developers.
Types of Games Available at Slot Sites
There are various types of slot games available at slot sites and casinos and they all come with different features, bonus rounds and mechanics. Here are some of the most popular types.
Classic Slots
Classic slots are the stereotypically type of slot that we think about when we think of slots. They are also known as traditional slots and they typically come with three reels and are easy to play. They can often have symbols such as 7's, bars, cherries or bells. They appeal to new slot players due to their simplicity.

| Mega Joker | 99% | Pub Casino |

| Double Diamond | 96.09% | Barz Casino |
| Triple Chance | 96.15% | Grand Ivy |
| Jackpot 6000 | 98.86% | Peachy Games |
Video Slots
Video slots are much the same as classic slots and are very traditional in their appearance and they are often played on a 3X3 reels grid. Some of the best video slot titles are Mega Joker, Starmania and Reel Rush.

Progressive Jackpots
The appeal with progressive jackpot slots is that there can be no ceiling to how high the jackpot can reach. That's because the top price grows with every spin played until it is won. When someone is lucky to win the jackpot the prize resets and the process begins again.
| Jackpot Slot | RTP | Available At |
| Mega Moolah | 96.09% | Barz Casino |
| Divine Fortune | 95.97% | Peachy Games |

| MegaWays Slot Name | RTP | Available At |
| Bonanza Megaways | 96.00% | Peachy Games |

| Monopoly Megaways | 96.50% | Playzee |

Slingo and Hybrid Games

Payment Methods Available at Slot Sites
Knowing what payment providers are available at a slot site is an important factor for you to consider when choosing a new platform. That's because you need to ensure that the slot site accepts your preferred payment method and you also want to use a website that offers fast and secure withdrawals. Here are some of the more popular banking options to look out for.
Debit Cards
Debit cards such as Visa and Mastercard are one of the most popular types of payment method due to their global accessibility. It's also a payment method most people already use and therefore they like the familiarity they get when using it.
eWallets
Electronic wallets are becoming more and more popular at casinos and slot sites as the processing times can often be faster than using a debit card. Some of the most popular ones are PayPal, Skrill, and Neteller.
Prepaid Cards
Prepaid cards, such as Paysafecards, are cards that you top up either online or by paying cash in a shop that offers this service. Their biggest appeal is that you can't over spend on them as once the balance has run out it needs to be topped up again.
Pay By Phone
Pay by phone payments is quite a unique concept but it has been around for a while now. These payments let you charge the payment back to your phone bill. This can be handy as you don't have to pay anything upfront, however, they usually come with small maximum deposit limits.
| Payment Method | Deposit Limits | Withdrawal Limits | Possible Fees | Withdrawal Times |
| Debit Card | High | High | Yes | 1-3 Days |
| eWallet | High | High | No | 12-48 Hours |
| Prepaid Card | Medium | Medium | Yes | Within 24 Hours |
| Pay By Phone | Low | Not Available | Yes | Not Available |
How We Rate the Best Slot Sites in the UK
As we have said there are various factors to consider when choosing a new UK slot site. Every player will either focus on different aspects or prioritise them differently. Here are what we look for and which every new player should think about when choosing the best UK slot sites.
Step 1: Licensing and Regulation
Yes, many think of this part as boring and would rather skip to what games or bonuses are available but trust us, this should be your starting point. You need to ensure that the slot site you're using has a license to operate in the UK and that the games on their website are regulated. <br> </br> This information is easy to find. It's usually on their website or you can check on the UK Gambling Commission's website. Ensuring that the platform you use is licensed means your personal and financial details will be safe and that you will get paid should you win.
Step 2: Game Variety and Software Providers
Now the fun part! Check that the slot site offers the games or at least the types of games you like to play. There is no point finding a reputable licensed casino to play at only to find that they don't have games you like to play. <br> </br> Another thing to look out for is what software providers their games are made by. The best games developers will only partner with the best online slot sites, so this will give you an indication of their reputation. Also, be partnering with the best developers you know that the games catalogue is likely to be updated regularly with the latest slots.
Step 3: Bonuses and Promotions
The first thing to do here is to compare the welcome offers available. Not only that, check all of the terms and conditions that come with them. There is no point accepting a huge welcome offer if it comes with unrealistic wagering requirements that you're likely never to meet. <br> </br> Also have a look at the promotions they typically run on a weekly, monthly or seasonal basis. Check if they have a VIP program. You want to know that you will be rewarded for your loyalty.
Step 4: Payment Methods and Payout Speeds
You need to make sure that not only does the casino offer secure and fast transactions, but that they offer one that you typically like to use. To give you some idea about payout speeds, the typical industry average is between 2-3 days.
Step 5: Mobile Compatibility
Lastly, check that the platform you're going to be using works on your mobile device. Most slot players these days play on their mobile as its easy and convenient and you can generally play from anywhere with an Internet or mobile connection. Make sure that the games load and adapt to your screen size and check that you can do everything on your mobile that you would on your PC or laptop like deposit, withdraw or contact customer services.
Responsible Gambling at UK Slot Sites
You always need to make sure your gambling sessions are fun and that you stay in control. As such, we would recommend choosing UK slots sites that offer responsible gambling tools. These are tools that you can use yourself to ensure your safety. They include things like:
- Deposit limits
- Time limits
- Take a break features
- Self exclusion options
Remember, you will never be judged for using any of these tools or for asking for help. It's why they are put in place, to make sure every player feels safe.
