Why play at casino sites UKWhy play at casino sites UK

The answer is simple – because top casino sites offer the absolute best experience to UK players regardless of your preferences and playing habits.

Whether a casual player who enjoys popular slots such as Starburst to jackpot chasers seeking that life-changing win, they offer entertainment and big win potential in equal measure.

They also appeal to high rollers and VIPs that like to stake big and win even bigger or table game fans who enjoy a more classic and traditional casino experience.

Our editor, James King, had to say this about why he only plays at the best online casino UK:

“There are thousands of online casinos in UK, but by playing at the best you can be sure you receive a top-rated experience across all of the main criteria.

Five-star casino sites excel at everything, from design to games to bonuses, loyalty schemes, payments and customer support, so why would you want to play anywhere else!”

Fun factorFun factor: the casino must deliver a fun and entertaining experience to players, whether through the theme, slots offered, tournaments, bonuses or loyalty scheme.

Some casino sites just have a sense of excitement and energy about them, which makes them a happy and safe place to play your favourite games.

Fun factor points can also be earned by offering the best games, from jackpot slots to table games via live dealer casino and even bingo, poker and instant win titles.

If playing at the casino puts a smile on our faces, then it will score highly for fun.

Bonuses and incentivesBonuses and incentives: top casino online UK sites offer some of the most generous and rewarding bonuses and offers to their players, from the welcome package to on-going incentives.

When reviewing a site, we pay very close attention to the offers available and whether they add value to your play. We also consider terms and conditions and play-through requirements.

Those that make this list offer appealing bonuses but, most importantly, appealing bonuses that come with favourable terms and conditions.

Game lobbyGame lobby: for a truly awesome online experience, players need to be offered a truly awesome range of games to play.

The best online casinos UK will stock their lobbies with 1,000+ titles from the major game developers, including NetEnt, Microgaming, Big Time Gaming, Red Tiger and more.

The quality of games is taken into account. Our reviewers like to see a mix of blockbuster slots combined with branded games and new titles that are set to top the charts.

If the online casino site can offer all of this and more, then it will receive top marks for game lobby.

SoftwareSoftware: the software that powers the casino has a huge impact on the experience you receive as a player – it must be modern and fast but also dependable and reliable.

There are a huge number of software providers and some are better than others.

As part of our review, we investigate the software provider behind each site we test and promote and only work with those at the cutting edge of the industry.

Of course, those that make our list are powered by the most celebrated software providers such as SkillOnNet, Microgaming, NetEnt and Playtech.

PayoutsPayouts: to be considered a top casino site, the casino must offer super-fast transaction times, but particularly when it comes to payouts.

While deposits are usually instant, the time taken for funds to be transferred from your real money wagering account into your bank account can vary.

Our reviewers check payout times to see if they align with the average times claimed by the casino. If those times are fast and so long as they are verified, the casino will be awarded good marks.

SafetySafety: all of the casinos we recommend are established brands that have been endorsed by the UK Gambling Commission and other regulators.

This means they have the required responsible gambling and safe gaming processes and tools in place to ensure you can stay in control of your play.

The casino sites on this list go above and beyond to make sure players are safe and protected and that is why they are listed among our top UK online casino brands.

That being said, all of our recommended brands are UKGC licenced and are accomplished at protecting players and making sure they gamble safely.

What to expect at UK casino sitesWhat to expect at UK casino sites

Now that we have explained what top online casino UK sites are, as well as providing a list of our top ten sites ranked in order, let’s take a closer look at what you can expect at these sites.

First up, we lift the lid on the types of games you will find at internet casino sites as this is one of the most important factors we consider when reviewing and recommending brands.

Games found at casino sites

If you are looking to access the greatest range of online casino games, then our recommended casino brands are just what you need as they all offer more than 750 titles.

Below, we list the different types of games you can expect to find.

SlotsSlots: these are the most popular type of online casino game and come in a variety of formats from classic three-reel to modern five-reel video slots.

Some developers have even created casino slots with six and seven reels, while others have designed games where the reels contract and expand.

Megaways slots can now be found in most slot site game lobbies – the mechanic was first developed by Big Time Gaming but has now been licensed to other developers.

These are just some of the slot developers stocked by our recommended brands:

  • Playtech
  • NetEnt
  • Microgaming
  • Scientific Games
  • IGT
  • Yggdrasil Gaming
  • Quickspin
  • Thunderkick
  • Pragmatic Play
  • Play’n GO
  • Fantasma Games
  • Push Gaming

This means that when playing at our tried, tested and recommended sites, you can be sure you will never run out of slot games to play.

Table GamesTable games: the best casino sites UK also stock a great selection of table games, including blackjack, roulette, poker, baccarat, punto banco, pontoon and money wheel.

This is great for casino players that like to mix and match playing slots with playing their favourite table games while some players simply prefer table games to slots.

Live CasinoLive casino: live dealer combines the thrill of playing tables games in a real casino with the convenience of online play.

Most sites offer live games from providers such as Evolution Gaming, NetEnt and Pragmatic Play, covering roulette, blackjack, poker and live money wheel.

Some even allow casino players to access live dealer tables located on the floors or real casinos, allowing you to sit down and wager next to real players from your computer or smartphone.

JackpotJackpot: these games offer some of the largest casino prizes out there, with progressives such as Mega Moolah and Mega Fortune running into millions of pounds.

There are smaller jackpot games, too. This includes Red Tiger’s Daily Drop jackpots that must payout before a set time each day – prize pots usually reach £30k plus before they payout.

If you are looking for the chance to win big from relatively small wagers, jackpot games are certainly for you. The good news is, they are available at most of our recommended sites.

Instant WinInstant win: also known as scratchcard games, instant wins are lottery-style games where you reveal and match certain symbols to win a prize.

Some instant win games are even hooked up to jackpots meaning you can win large prizes from a relatively small stake.

Popular online scratchcard game providers include Instant Win Gaming and Realistic Games and their titles can be found a growing number of sites.

Lottery bettingLottery betting: this allows you to bet on the outcome of some of the largest lottery draws in the world, including the Powerball and Mega Millions in the US.

You do not buy a ticket to the draw and instead, bet on the outcome. But it works just the same as with a traditional draw in that you pick numbers and match them to win prizes.

In most cases, the jackpots are the same size as the official draw but, in some instances, they can be even bigger.

This is why we love UK online casinos – they offer such a huge range of games that ensure players are entertained for hours and days on end.

These are some of the most popular titles available at the best casino sites right now:

  • Bonanza (Big Time Gaming)
  • Extra Chilli (Big Time Gaming)
  • Pirate’s Plenty (Red Tiger)
  • Mega Moolah (Microgaming)
  • Age of the Gods (Playtech)
  • Gonzo’s Quest (NetEnt)
  • Dead or Alive II (NetEnt)
  • Razor Shark (Push Gaming)
  • Rich Wilde and the Book of Dead (Play’n GO)
  • Wolf Gold (Pragmatic Play)

Bonuses at the best casino sitesBonuses at the best casino sites

If you like to play with real-money casino welcome bonuses, then this website is certainly for you.

Discover everything there is to know about the best casino sites in the UK. We offer fair and expert advice on what top online casinos are worth considering.

These sites offer a huge range of generous incentives, including welcome offers and on-going promotions. Below, we look at the different types of bonus up for grabs.

Casino BonusWelcome bonus: casinos welcome new customers with a variety of offers, from deposit match casino bonuses to free spins and even cashback.

In most cases, the welcome offer is a combination of a deposit match and free spins and is unlocked once you have signed up and made a deposit.

An example of a welcome package is:

Deposit match of 100% up to £100 plus 50 free spins on NetEnt’s Starburst.

Most welcome offers apply to your first deposit, but some are extended across your second, third and even fourth deposit for even more added value.

Casino BonusDeposit bonus: this is where the online casino matches the amount you deposit by a certain percentage and up to a certain value, giving you more cash to play with.

The percentage matched by the site is usually 100% and the value matched can be anywhere between £10 and £2,000 or more.

Casino BonusFree spins bonus: this is where you are granted a set number of free spins on a slot game – usually a NetEnt title such as Starburst – once you have signed up and deposited at the casino.

Free spins are exactly what they say they are – spins on a game that does not require you to use your own cash. The spin value is usually £0.10 but it can be more.

Casino BonusNo deposit bonus: this is when the online casino gives you a small amount of cash to try its games without requiring you to make a deposit first.

In most cases, you will have to create an account at the casino before the bonus funds are sent to your player account.

Casino BonusNo deposit free spins: similar to a no deposit bonus, no deposit free spins are awarded by the operator once you have created an account and before you are required to make a deposit.

This allows you to enjoy a small number of spins on a popular slot title without having to use any of your own cash.

Casino BonusCashback: this is where the casino gives back some of the money you deposit and wager. Cashback amounts are usually between 10-20%.

You may have to wait for your cashback to reach a certain value before it can be withdrawn, or you might have to wait 24 hours for it to be unlocked.

Casino BonusReload bonus: this is similar to a deposit match bonus but is offered to existing players when they top up their account with an additional deposit.

It works just the same was as a deposit match bonus, with the casino matching your deposit by a certain percentage and up to a certain value.

No deposit casinos are becoming increasingly popular with UK players as they allow them to try the site without having to spend any of their own money.

Some of these casinos even make our best casino site UK list, but just remember that no deposit offers – whether a bonus or extra spins – often come with terms and conditions.

This applies to all casino bonuses and is something that players need to be aware of and consider before claiming a bonus or offer.

These are just some of the conditions that bonuses can come with:

  • Min deposit required to unlock the offer
  • Max bonus offer you can claim
  • Time limit to use the bonus
  • Max bet limit on free spins
  • Max win limit on free spins
  • Wagering requirements

Even the best casino sites impose terms and conditions on their bonus offers, as do the best new online casino UK sites.

While it is important to understand all of the T&Cs attached to an offer, the most significant is the wagering requirement you have to meet before you can withdraw bonus winnings.

Wagering requirements are applied to deposit match bonuses as well as free spins. Below, we take a closer look at how they work for each.

Casino BonusDeposit match bonus: the wagering requirements, or playthrough requirement as it is also known, can be applied to the deposit itself or the cash that you win using the deposit.

In some cases, it will be applied to both the deposit made by you and the deposit awarded by the casino, although this is not often the case.

This is an example of a deposit match bonus wagering requirements:

Bonus: 100% deposit match up to £100

WR: x60 on the deposit bonus

You deposit £100 and claim the 100% deposit match of £100. The wagering requirements applies to the deposit bonus cash from the casino.

This means you will need to wager the £100 x60 before you can withdraw any winnings from the bonus as real-money cash.

This works out as:

£100 x60 = £6,000.

This means you will have to re-wager £6,000 before you can withdraw the bonus as cash.

Casino BonusFree games bonus:

Bonus: Deposit £10 and get 30 free spins on NetEnt’s Starburst

WR: x30 on free spins winnings

You deposit £10 and unlock 30 free spins on Starburst. The wagering requirements applies to the winnings you accrue from the free spins.

For this example, you win £50 from the free spins. This means you must wager the £50 x30 before you can withdraw your winnings as cash.

This works out as:

£50 x30 = £1,500.

This means you must re-wager £1,500 before being able to transfer the £50 from your bonus balance into your real-money wagering account.

For bonuses that combine a deposit match with free spins, you will have to complete wagering requirements for both aspects of the bonus – the deposit and the free games.

Of course, for both bonuses, you might find that in trying to complete the wagering requirements you lose your current real money balance.

If you do, you then have the option to deposit into your account and continue to play through the wagering requirement or sacrifice the bonus amount remaining.

This is why it is important to understand how T&Cs apply to bonuses and what it actually means when it comes to winnings and what you have to do to be able to withdraw.

The good news is that some of the best online casinos in the UK no longer impose wagering requirements on bonus offers such as deposit matches and free spins.

This means you get to keep all of your winnings from the deposit bonus and free spins and can withdraw them as cash at any time with no limits imposed.

If you haven’t claimed a welcome offer at a best online casino in the UK, follow these simple steps.

  • Browse our list of casinos and select the one that appeals to you most
  • Read the bonus information and if you want to accept the offer, click “Claim”
  • You will be sent to the casino where you will be asked to create an account
  • Once you have done this, make a deposit and then accept the welcome offer
  • The welcome offer will then be credited to your account
  • If the offer includes free spins, you will be taken straight to the game

It really is that simple.

Loyalty schemes at best casino sites in the UKLoyalty schemes at best casino sites in the UK

When playing at a best online casino UK you will most likely find a loyalty scheme that rewards you for continuing to play at that site.

There are several different types of loyalty scheme from points-based level up variants to those that require you to complete missions and tasks to unlock trophies.

In most cases, loyalty schemes are also hooked up to VIP clubs which are reserved for the most loyal players and high rollers.

Below, we take a closer look at the different loyalty schemes.

Mobile Casino SitesMobile Casino Sites

Casinos in the UK can be accessed from desktop, laptop and of course mobile devices such as smartphones and tablets.

This means you can access these hugely popular sites no matter where you are or what you are doing, whether sat at home on the sofa relaxing or riding the bus to work.

Mobile casinos can either be accessed via dedicated apps downloaded from the Apple App Store or the Google Play store or via web-browser.

You will receive the exact same experience when playing a mobile casino, including the welcome package, games, payment options and loyalty schemes, as when playing from a desktop.

Points Based

Points-based: this sees players earn points for carrying out certain activities at the site, including depositing and for placing bets and wagers.

For example, you may earn one point for every £20 deposited into the casino, or you may earn one point for every £10 wagered on slots and table games.

The more points you earn the more levels you clear and the more perks and rewards you unlock.

Missions and tasks

Missions and tasks: this is when the casino requires players to complete challenges to earn trophies which in turn can be used to unlock perks and prizes.

Tasks might be creating an account, making a deposit once a month, playing specific games or even hitting certain features and wins within games.

Trophies are usually displayed in a cabinet and you receive rewards and perks for collecting certain trophies and completing tasks.


Cashback: some sites offer cashback as a way to reward your loyalty. This is usually a percentage of your deposits, but it can also be a percentage of your losses over a set period of time.

Regardless of the type of loyalty scheme offered, the best casino UK online will have a special VIP club dedicated to their most loyal and big-spending players.

To gain entry to these exclusive clubs, you must climb through all of the levels of the loyalty scheme or be invited to join by the casino.

If you are lucky enough to reach VIP status you can expect the following perks:

  • Personalised bonuses and promotions
  • Higher deposit and withdrawal limits
  • Your own VIP account manager
  • Invites to exclusive events
  • A present on your birthday

New casino sitesNew casino sites

New casinos launch to UK players all of the time, offering fun and interesting themes, hearty welcome offers, thousands of mobile slots and mission-based loyalty schemes.

Some of these are considered among the online casino UK best, delivering an excellent player experience despite being new.

This is because they are powered by the latest technologies and, in some cases, are run by teams behind some of the most established casinos so they know how to look after players.

Casino Sites with the best payoutsCasino Sites with the best payouts

Players often want to know the average payout of the casino to determine whether it offers favourable odds of winning. While online games are random, some payout more than others.

The payout percentage of the casino is calculated by adding the return to player (RTP) of all the games offered together and then dividing it by the total number of games.

This allows you to see what percentage, on average, of total bets placed at the casino is returned to players as winnings.

These are three high payout casinos:

  • PlayUK
  • bCasino
  • 888Casino

The sites we recommend are dependable, safe and secureThe sites we recommend are dependable, safe and secure

All of the sites that make our list have been verified by our expert reviewers and meet the highest possible standards when it comes to player experience and protections.

Each site is licensed by the UK Gambling Commission, a legal requirement to accept UK players, and have the required processes and tools to ensure you have fun while remaining safe.

This includes using SSL Encryptions and firewalls to safeguard transactions and personal data, as well as using random number generators to determine the outcome of all games and wagers.

As required by the UKGC, random number generators are regularly tested by third parties to ensure they are working as they should be.
