What is a slot site?

UK slots sites let you stream online slot games using free play or real money credits. You don’t download the slots, but instead play the games live on your devices – such as a laptop, iPad or smartphone – using wi-fi, data roaming or an internet connection. In the UK, slot sites must be licensed and regulated by the UK Gambling Commission. If an operator does not hold a UKGC licence, then it’s illegal for you to join and play if you’re a UK resident.

How we rank online slot sites

In this article, we’ve gathered together the top online slot websites for your convenience. Using these quality casinos, you’ll access the very latest games, bonuses and software from the gaming industry. Tried and tested platforms, reputable brands, and trusted names. But how did we do it?

When it comes to joining online casinos and playing slot games, we’ve got years of experience. It’s our main objective to help players find the top slot sites using that experience. That’s why we’ve come up with a list of top tips for choosing your next place to play – it’s also how we get our rankings.

  • UKGC Licence
  • Responsible gambling tools and advice
  • Platform
  • Game search
  • Online slots and casino games
  • New games
  • Welcome bonuses
  • Promotions
  • Customer support
  • Withdrawal times
  • Payment methods
  • Security

UKGC Licence

It’s probably the most tedious aspect, but it’s also the most important. The UK Gambling Commission regulates online gambling in Great Britain, including arcades, lottery operators, gaming machine providers, casinos and slot sites in the UK. They are responsible for issuing licenses to gambling websites and can take action if they don’t follow the rules.

In a nutshell, the UKGC is there to provide a well-regulated market, one in which consumers (players) have confidence that they will be well treated and protected. That’s you! 

By ensuring that gambling is conducted fairly and openly, we’ll get a better service from our online casino. That’s why you should always look for a license – and we do.

Responsible gambling tools and advice

While some players gamble for fun and enjoyment, others think of gambling as a way to make money, spend more than they can afford, or use gambling to distract themselves from everyday problems. Choosing the right casino should always include websites with responsible gambling tools and clear guidance for safer gambling.

The best slot sites support players to gamble safely.

Before picking a casino to join, we look at how well the brand supports responsible gambling and what tools players have at their disposal. Some of these include:

  • Self exclusion
  • Session reminders
  • Reality checks
  • Take a break
  • Gamban – allowing you to block betting sites on your computer
  • Setting deposit limits
  • Stringent age verification processes
  • Online activity statements
  • Self-assessments
  • Support and guidance


When we talk about platform, we’re talking about instant gaming, performance, design, security and usability. Is it a mobile slots site? Is it, therefore, mobile-responsive? How easy is the website to use, can you find games quickly, how many online slots.

Slot sites like Casushi offer great design and features

What about menus and content placement. Can you play for free with demo games etc.? All of this points to a good or bad user experience.

An effective casino platform has both great design and great games content. The site structure should keep slots and promotions content well-organised. Additional features that help you search casino games, bonuses, and customer support will also make the experience feel aesthetically pleasing.

If you struggle to use or enjoy an online casino, that’s a clear indication that what the site offers is not up to scratch. 

When players are too overloaded with choice, they can’t process the task. That’s why game search is a must. If you’re an online casino with thousands of ways to entertain, this should be well-organised and easy to find. If you can filter by provider, paylines, cost per play, features and genre – then the whole experience is improved.

Slot sites with game search allow players to find slots and games quickly. Simply put, it’s a function that connects you to games content faster, allowing you to focus on particular slots, themes and slot game bonus features.

Online slots and casino games

If you choose a site with a good variety of online slots and casino games, then it’s less likely that you’ll need to look elsewhere for entertainment. That’s why we’ve selected websites with the best slots from the top providers, so there’s more than enough to play. Free play is also important; demo content is a great feature to try a game before gambling with real money.

We rate sites using quantity, quality, and integrated software providers from casinos with thousands of games to those with original content. That includes games from Play’n Go, NetEnt, IGT, Playtech, Big Time Gaming and many more developers. We’re also looking for a good mix of popular slots, top slots, classic games and a reasonable amount of new games.

In-play features and bonuses

Consider, too, that most new online slots come with variable betting rates and features. That’s a huge incentive if you’re looking to play minimum bets, but on games with lots of bonuses and on reel modifiers. It’s a misconception that the best slot sites for winning are those with high RTP slots, but instead those sites with lots of features-rich games that you can play from just 10p.

As a good indicator, some of the best UK slots might offer the following features:

  • Free spins
  • Pick a win
  • Multipliers
  • Nudges
  • Wilds
  • Reel modifiers
  • Gamble options
  • Expanding symbols
  • Bonus games
  • Progressive jackpots
  • Ways to win
  • Tumbling reels
  • Payline mechanics
  • Bonus levels

New games

With so many new slots being released all the time, you might miss news of up and coming casino games. If you want to stay up to date on new slot releases coming to casinos, it’s best to be at one that gets the latest games content. 

We don’t like missing out on brand new slot games. For the most part, new games mean better graphics, gameplay and features. As developers try to improve their products, players can expect more for less in terms of cost per play and features. In the future, gambling on slots in the UK will mean smaller bets on games with more extensive features, and providers are well aware of the requirements.

In our book, the top-rated online slots sites have a good portion of new online slots in their lobbies. New stuff is something we take seriously.

Welcome bonuses

Everyone likes a good slot welcome bonus. For most of us, joining an online casino nowadays, it’s the first thing we notice. From free spins to deposit matches, and often a combination of both – welcome bonuses help operators gain customers. 

But it works both ways too; bonuses also provide players with an extra incentive through free spins, a match bonus or free play on selected games. And, because slot games contribute to 100% of the wagering requirements, it’s the perfect type of bonus.

The UK has a particularly large slot sites market with healthy levels of competition. Why is that so important? Welcome bonuses are valuable because they encourage players to sign up, verify their age, provide personal data, bank details, and finally, a deposit. If those players stick around, the welcome bonus value decreases while profits for the site go up.

As part of our ranking process, we compare bonuses from established casinos to brand new slot sites. 


In this day and age, most UK players do some research before joining an online slots website. But few players look past the initial welcome bonus. One of the main things you should consider is promotions following registration – how the casino makes your membership worthwhile after signing up.

There are several ways brands incentivise members, often with promotions scheduled across the calendar month – these include daily and weekly prize drops, cashback on losses, free spins days, leaderboard competitions and regular deposit bonuses. 

Slot games are hugely popular in the UK, and are usually the first port of call as far as online gambling is concerned. So with that, it’s best to find a site that tailors its promotions towards slots players. Whenever we review a particular casino, we’re looking for promotions that include new games, free spins, bonuses and anything else that rewards online slots play.

Customer support

If a slot sites customer service is unhelpful, unreliable, or just plain hard to get in touch with, players will leave in droves. Is it really too much to ask in return for spending your hard-earned money on casino games? Providing excellent customer support should be the main objective for the house, and it is for the top brands.

Great customer service means following best practices like valuing a players time, providing resources, game information, payout rates on request etc. Staff who know their online casinos, online slots, software and platforms for the benefit of players when they need help is the pinnacle of customer support. Granted, it’s not easy to find this level of service, but we try.

New slot sites will offer 24/7 live chat, freephone telephone, email and FAQs as part of their customer support package.

When we check UK slots sites, we look for response times, attitude, depth of knowledge, problem-solving initiative and personalisation. Basically, if we need help, do we get that help, and how quickly does that help come.

Withdrawal times

If you choose to play casino slot games for real money, you’ll likely want to know about withdrawal times. Playing with real money means you can win real money, and you’ll want to get that money out. The best slot sites will make this process easy.

On average, all processed withdrawals should be credited to your bank account within 3-5 working days. Be wary of terms like lightning-fast withdrawals or instant withdrawals. While casinos can process your withdrawal request quickly, that doesn’t mean a payment into your bank.

Withdrawal payment time frames vary from casino to casino, but each one follows generic guidelines. E-wallets are faster than debit cards; acceptance periods are within 24 hours, email notifications sent on completion of cash transfer etc. – these are standard expectations.

Players want to win and then withdraw those winnings. When comparing the best UK slot sites, we look at how easy, fast, and restricted the withdrawal process is between each casino.

Payment methods

Players are starting to expect to use their favourite payment methods on slots sites across the web. With the growing popularity of e-wallets and pay by mobile phone, UK casinos need to catch up if they’re not doing it already. While there’s nothing wrong with visa debit cards, each website should offer a good selection of deposit and withdrawal options.


Slot site security prevents the exploitation of website data, cyber attacks, hacking and any other activity associated with cybercriminals. By using Secure Sockets Layer (SSL), an online casino secures and encrypts the data shared between the player and the casino. As a customer, you always want to see https:// when visiting any site you trust with your essential information.
