UK Online Casinos - Where to find the Best UK Slots Sites

This page is designed to answer one main question - where can I find the best UK online casinos? The answer is right here, and much more. Not only do we list the most popular, reputable, safe and generous UK online casino sites you can join right now, but we also explain how we chose these casinos and what makes them superior.

So read on to learn about the key rating criteria, features and characteristics we use to choose the very best slot-focused UK casinos online - without exception.

• Licensing – As mentioned above, the only casinos we associate ourselves with and that you should only ever play on are of the licensed and regulated variety, specifically in the UK. That said other online gambling licensing jurisdictions that are trustworthy and reputable include Gibraltar, Kahnawake (Canada), Curacao, Antigua & Barbuda and Malta.
• Games – Choice is king at top UK online casinos, where you can choose from the hundreds of multi-platform browser-based games (and downloadable games, if applicable) that cover the main categories. From classic, video and progressive slots to video poker, blackjack, roulette, baccarat, keno, scratch cards and more, our casinos have them all.
• Payouts – Only online casino UK games with the highest payout percentages a.k.a. return to player (RTP) are worth playing. This is expressed as a percentage and indicates how much of any currency unit wagered (on average, over time) is returned i.e. paid out to players as winnings. The rule of thumb is that any RTP from 95% and higher is worth playing.
• Banking – Having the ability to add funds to your virtual casino account and withdraw them easily and fast is a barrier to entry at the sites we promote. In other words casinos that let you make quick deposits and withdrawals via many recognised banking methods including credit cards, e-wallets, prepaid cards, bank transfers as well as cryptocurrencies.
• Players – The more players an online casino has, the more funds it has to invest in new games, even more generous no deposit and/or welcome bonuses, regular and very rewarding promotions and other player-friendly features. We only endorse casinos that are 100% proven, tried and trusted, with a much larger than average number of loyal players.
• Security – Security is paramount at online casinos in terms of ensuring that all of your personal information, financial transactions and balances are safe, secure and protected 24/7. All the casinos we feature use cutting edge encryption software and systems to safeguard all data and funds, and ensure your online play and transactions are 100% private.
• Fairness – In the casino business the house always has the advantage. That said we only find and feature UK casinos sites with games that have the most competitive and fair games i.e. games that can offer you the best chance of winning because their odds are fairer than most. This is achieved via cutting edge RNG (Random Number Generator) software.
• Endorsement – A quick and effective way of discerning if a casino is fair, decent and worth playing on is to check its homepage for an endorsement i.e. a 'seal' or 'badge' from one or more 3rd party independent online gambling auditing, certification or testing agencies or labs including eCOGRA, iTech Labs, Gaming Associates and Technical Systems Testing.
• Bonuses – Online casino bonuses offering a lot of free credits or free spins on the surface are one thing, while bonuses with the most lenient and thus achievable wagering requirements (as listed in the bonus T&Cs) are another entirely. As such the only bonuses we endorse are ones where you have a better than average chance of cashing out winnings.

In answer to the second question, highlighted below are the most common types of new player bonuses you can expect to find at rated UK casinos.

Common UK Casino Online Bonuses

• No Deposit Free Credit / Free Spins Bonuses - These are 100% free to claim and most allow you to cash out real money winnings if you meet the bonus wagering requirements in their T&Cs. To claim a no deposit bonus you just open a new casino account.
  Depending on the casino you'll be offered free credits (typically between $10 and $40) to play slots and various other games with or free spins (typically between 10 and 100) you can only use to play one or more specified slots.
  If you accrue winnings and fulfil the bonus wagering requirements, you'll be allowed to cash out some winnings (up to the maximum withdrawal limit) listed in the T&Cs.
• Welcome / Sign Up Bonuses - These bonuses require you to make a deposit to unlock them and work by 'matching' your bonus by a fixed percentage (usually 100%). That's why they're also called Match, Matching and Sign Up bonuses. If you meet their bonus wagering requirements in full you can cash out your bonus alongside your winnings.
• Cashback Bonuses - You can enjoy a weekly cashback i.e. a fixed percentage rebate of your total losses for the previous week. What's great about these bonuses is even if you're in the midst of a losing streak - albeit a temporary one - you'll always get something back. Most cashback bonuses are paid into your casino account every Monday.
• Refer a Friend Bonuses - Most online casinos will reward you with a little something with every friend you refer to them that goes on to make a deposit. While these bonuses are usually nominal, if you know a lot of online gambling fans these bonuses will start to add up pretty quickly.

How to Claim UK Online Casino Bonuses

Now that you know what the most common bonus offers are at UK sites, the next stage is figuring out which ones are right for you and how to go about claiming them as per the steps below.

What you need to know about online casino bonuses

• No deposit bonuses let you play real money games free
• Welcome bonuses help you pump up your playing funds
• All bonuses come with a long list of terms and conditions

UK Loyalty Reward Programs for Slots Players

All top UK online casinos have loyalty programs (also known as VIP loyalty programs) that are designed to reward loyal and regular players. In most cases you automatically join a casino's loyalty program the moment you start playing games for real money.

Loyalty programs are points driven which means you earn points for every (eligible) real money game you play (be aware different games typically contribute differently to your point count). Once you've accrued enough points (typically in blocks of 100 or 1000 or even 10000) you can redeem them for bonus cash.

The more points you earn, the faster you'll climb the casino's various loyalty program levels or tiers. Each has better rewards and incentives than the preceding one, such as larger, more exclusive bonuses, free spins, dedicated VIP managers, invites to special events, wagering free bonuses and faster than average withdrawal times.

Leading UK site Hello Casino has a very popular Loyalty Points Program where as a new player you'll automatically be credited with 500 Loyalty Points with your first deposit. See below how many points you'll earn per game for every £10 you wager:

Slots - 2 points

Scratchcards - 2 points

Video Poker - 1 point

Blackjack - ½ point

Roulette - ¼ point

For every 10000 points you redeem at Hello Casino you'll receive £10 in bonus cash.

Note: You are required to wager all bonus cash 35x times before the casino will allow you to transfer or transfer it. Also, you have three days from the date of redemption to use your bonus cash before it expires. Fortunately there is no maximum cash out for bonus-derived winnings at Hello Casino.

Best Deposit Methods for UK Casino Players

One of the cornerstones of playing at any decent UK casino site is the ability to get your funds into and out of your account easily, quickly and reliably. This comes down to the particular banking methods that a casino has partnered with.

The rule of thumb is that reputable player-friendly casinos offer payment methods that are common and widely available to their target players. These include credit and debit cards, e-wallets, prepaid cards, bank transfers and more recently digital coins such as Bitcoin, Dogecoin and Litecoin that are almost 100% anonymous and clear instantly.

In the table below you'll find the most popular banking methods chosen by UK players at virtual casinos.

The Best Casino Withdrawal Methods for UK Players

As you can see from the table above, most online casino deposit methods are instant, but the same can't be said for withdrawal options. With the exception of digital coins like Bitcoin, the best you can hope for is to get your cleared funds within a day or two.

So the question is which are the best withdrawal methods for UK players and why? Below we've highlighted a handful of the most popular methods that are a good choice of players based in the United Kingdom.

• Credit Cards - The biggest benefit of credit and debit cards is that they're so prevalent i.e. most people own at least one debit or credit card. In many - though not all - cases, if you deposited with a particular card you can cash out to that same card (check this with your chosen online casino before you make a deposit).
  Another benefit is that their transaction fees are negligible if any, and the majority of casinos welcome credit cards.
• e-Wallets - These are a preferred withdrawal method among many UK players because they are a quick and easy to sign up with and most casinos process the most popular ones which are Neteller, PayPal and Skrill.
  Although cash outs can take up to 24 hours to clear in your e-wallet account, the good news is you can order debit cards from most of them that let you conduct online transactions and cash withdrawals at any UK ATMs.
• Bank Transfers - Although not the fastest withdrawal method, many UK players prefer to cash out their online casino winnings to their regular bank account because they cut out any and all the middlemen.
