Slotsia’s Guide to Online Casinos

How Do Online Casinos Work?

Online casinos offer players a full ‘virtual’ equivalent to land-based casinos. They host a wide range of casino games at their sites, ranging from slot games to live table games played in real-time. Online casinos are also built to be fully mobile responsive meaning you can have a mobile casino with you on any device, wherever you are.

Online Casinos vs. Land-Based Casinos

There are some pretty big differences between online and real-world casinos. Both have their pros and cons, and it really comes down to your personal preference when deciding where you want to enjoy your casino gaming.

Online casinos have the key advantage of ultimate flexibility. With the advent of mobile-friendly sites and game design, you can enjoy casino gaming on any iOS or Android device from pretty much anywhere. As long as you have a data connection, there’s nothing stopping you from playing slots and live casino games.

Online Casinos vs Land-Based Casinos

With a brick and mortar casino, you obviously have to visit the location to play and adhere to any given dress codes. That said, you might enjoy the atmosphere, glamour and social aspect, which only comes from stepping inside a real-world casino. Plus, if you are there in person, then you can collect your winnings and cash out right away. Online casinos have to perform checks on players and rely on payment providers which can often take days to transfer your winnings into your bank account.

If you’re after the best bonuses, biggest RTP percentages and the biggest jackpots, then online casinos are the way to go. Casino sites can beat land-based casinos on pretty much every front because of their much smaller overheads. Without physical buildings and machines to maintain, they can give much more back to you as a player with offers, bonuses and other potential prizes.

Online casinos are much more regulated than their brick and mortar counterparts and do not take advantage of problem gamblers like land-based casinos may do. Thanks to strict casino licensing from the Gambling Commission, players in the UK are very well protected from rogue online casinos and fraud.

As you can see below, playing online has many more benefits than the traditional land-based casino setup:

Pros of Online CasinosPros of Land-based Casinos
Play anywhere
Whether you opt for a desktop or mobile device, technology has advanced to the stage where you can play games at your own convenience to the same high standard.
The experience
Most land casinos in the UK are huge establishments that have a range of things to do as well as gamble – this includes restaurants and sports bars on a 24/7 basis. There is also arguably a better atmosphere, though live casinos replicate this pretty well.
No dress code
There is nothing stopping you from getting dressed to the nines to play your favourite casino titles from the comfort of your home, but thankfully it is also not enforced, unlike playing at some land casinos.
Cash withdrawals
At the end of a casino session, you simply had to the cashier’s desk and exchange your chips for cash. No online gambling site can compete with this convenience, whichever payment method you choose.
Welcome bonuses
Physical casinos may well reward you when you make a deposit for the first time, but it is unlikely to be as generous as one at an online casino, where you can expect free spins and a bonus boost.
Array of games
The best online UK casinos have a huge games lobby from a wide variety of developers, allowing you to jump seamlessly from one area to another. Live titles such as Monopoly and Dream Catcher offer a completely unique experience.

What Makes a Good Online Casino?

When looking for an online casino to play at, it’s important to think about the following criteria to help you choose the best one. These are the basics that any UK online casino that’s worth your time and money should excel at.

UK online casino licence

💠 Trustworthiness & Licence

You want to be sure that you only play at online casinos which you can trust and are properly regulated. Therefore, it’s vital that you only play at UK casinos which are officially licensed by the British Gambling Commission. This licence is known the world over for being one of the most stringent and it will help to protect you as a casino player within the UK.

You can check if a casino holds an official Gambling Commission licence by looking for the details and logo in the footer of the site. You’ll also be able to double-check the full details of their licence at the Gambling Commission website to be certain that it’s genuine. Here at Slotsia we only ever recommend officially licensed casinos to UK players like you.

Real Money Bonuses

💠 Good Bonus Offers with Fair Wagering Requirements

Landing a great bonus is one of the main reasons you’ll want to sign up and start playing at any online casino. The best UK casinos offer some very tempting bonuses in the form of free spins, cashback, bonus cash or loyalty points. It could be just one or a combination of these bonus types which you could claim when you sign up as a new player.

It’s important to know that not all bonuses are created equally though. Many offers will require you to drop in a minimum deposit to trigger them, and most will also come with wagering requirements attached. This means that you’ll need to play through (wager) your bonus amount or winnings from the bonus a specified amount of times. You’ll want to only take on bonuses which have fair or no wagering requirements to stand a chance of fulfilling them. The industry average is thirty-five times (35x) and anything more than forty-five times (45x) can be classed as high.

UK online casino games

💠 High-Quality Selection of Games

Any good online casino needs to have a decent library of games to keep you entertained and coming back for more. Don’t be impressed just because a casino site boasts a large number of slot or table games – it’s quality, not quantity as the old adage goes. You want to be taking a closer look at the game developers that are powering the games at any given casino. It’s no surprise that some of the most highly rated games are produced by the industry’s most respected games studios.

Look for games produced by the big brands like NetEnt, Thunderkick, Pragmatic Play, Quickspin, Yggdrasil, Microgaming or Play’n GO.

These guys have been producing high-quality casino games for several years and have countless hit titles between them. If you prefer some live casino action then look out for Evolution Gaming and NetEnt Live who are the industry leaders in hosting UK real-time table game and game show live streams.

UK online casino payment methods

💠 Variety of Payment Methods

A solid selection of verified payment methods is another key criteria in finding a good UK casino to play at. Some of the most popular and secure payment platforms include Visa Debit, Mastercard Debit and e-wallets such as Skrill, Trustly or PayPal.

These payment methods can usually be used for deposit and withdrawals at UK casinos. Just make sure that you can still claim your welcome offer when using your chosen payment method as exclusions can apply.

The general rule is that the larger the range of accepted payment methods, the more trustworthy the casino is. Most payment platforms don’t want the added risk of working with illegitimate UK casinos and will only sign up if the site is licensed by the Gambling Commission. You want to look for a casino which is transparent in all its payment practices and offers detailed and up to date information on each provider. Any additional rates or fees should also be clearly advertised in advance, so you’re not hit with any unexpected charges.

Another major consideration when looking at UK casinos is the withdrawal times given. You don’t want to be waiting days on end for those hard-fought winnings after all. Therefore, always look for a casino which can offer speedy withdrawals via trusted payment providers.

UK online casino user experience

💠 Good User Experience & Interface

UK casinos come in many, many forms these days – from the most basic of designs to full-on bells and whistles. The most important thing to focus on is your own experience of a casino site, so don’t get too distracted by all the fancy fluff. Are you able to easily find all the games that you want to play and do they load up without any issues?

At the end of the day, you want to seek out a casino which you feel comfortable using on both desktop and mobile. Some casinos might even offer a dedicated mobile app for their players, so download that and see how it feels to use it.

There’s sure to be a casino that caters to every player’s taste. If you are into the whole ‘gamification’ thing and enjoy side quests and competitive casino play then there are plenty of sites offering that. If you just want speedy access to your favourite games without any extras, then you’ll also find plenty of sites which offer just that too.

UK online casino customer service

💠 Excellent Customer Service and Player Protection

Wherever you are enjoying your play, it’s important to feel that the casino is there for you if you need them. This is why having great customer service and support is so important. It’s often overlooked in favour of tempting welcome offers, but you need to know that if things go the way of the pear, the support team can step in and resolve your issues quickly. You also want to know that they are on your side if any disputes should arise.

You also shouldn’t underestimate the value of being protected as a player at a UK casino. The Gambling Commission licence should help to ensure that all casinos have procedures and tools in place to help you gamble responsibly. You should be able to set limits on the amount of time and money you wish to spend at any online casino. It’s all about putting you in control of your casino play so that it always remains fun.

The Dos and Don’ts When Choosing an Online Casino

As we’ve seen, there are some key things to consider when seeking out a fantastic UK casino to play at. Here’s a simple comparison of what a good UK casino looks like versus a non-legitimate site which should be avoided:

Good UK CasinosNon-legit UK Casinos
✔️ Trustworthy brand with an official GC licence❌ No official UK casino licence
✔️ Good and fair wagering casino bonuses on offer❌ Deceptive bonus offers with high wagering requirements
✔️ Great selection of high-quality casino games from the best developers❌ Poor or outdated selection of casino games from unknown developers
✔️ Large list of trusted payment providers❌ Small selection of untested payment providers
✔️ Easy to navigate mobile friendly casino site ❌ Difficult to use site that isn’t mobile responsive
✔️ 24/7 customer service support that can resolve issues quickly❌ Unresponsive customer support with very limited hours who ignore your issues

Red Flags

No UK Licence – Only play at fully-regulated casinos with a UKGC licence.
Payment Fees – Avoid online casinos that charge you every time you deposit or withdraw funds.
High Wagering Requirements – Look for casinos with fair bonus terms.
No Payout Information – Don’t play at a casino if it doesn’t display the RTP of its games.

These ‘Red Flags’ are a good warning sign that this is maybe a casino which you should avoid playing at. The good news is, it’s easy to find out if any UK casino has any of the red flags mentioned here.

To find the GC licence information, take a look at the footer of the casino. This is usually where all their licensing information will be displayed, including the licence number. You can cross-check this at the official Gambling Commission site to ensure it is a legitimately issued and valid UK casino licence.

Checking the payment pages of the casino should tell you if they will apply any fees to your withdrawals or deposits. If there is no dedicated payments page with information, check the FAQs section or contact their support team to get some clarification.

The wagering requirements of any bonus offer should always be stated in the significant terms and conditions right next to the offer itself. If they are not clearly visible, then check the full terms and conditions.

Another legal requirement of a UK casino licence if the visibility of payout information (RTP). It should be easy to find the house edge of any games in its paytable or info tab.

How to Sign Up to an Online Casino in the UK

It’s easy to sign up and start playing at one of our recommended UK casinos. Simply select your favourite offer from the list at the top of this page and click on ‘Play Here’ to begin. You’ll then just need to sign up and create an account at your selected casino. Don’t forget to claim your welcome bonus when prompted. Here are some questions we get asked most when it comes to signing up at UK casinos:

💠 What personal details do I have to give when I register my new account?

Most casinos will ask for the same basic information such as your full name, address, mobile phone number and date of birth. You might also need to enter your gender and occupation to complete the account sign up process.

💠 Do I have to verify my account right away?

UK casinos are required to verify all new player accounts by law. Most will attempt to do this automatically with the details you provide during signup. If they are unable to do this or your withdrawal amount triggers their verification process, then you’ll need to provide further documentation.

💠 What documents do I have to give to confirm my identity?

When you are required to verify your account, it will usually take the following three different types of documents:

💠 How do I claim the bonus?

Different casinos will have different methods for claiming their casino bonuses. Some will have a checkbox to opt-in to the bonus when you make a deposit. Others might require a special bonus code to be entered which can be found in the bonus offer text.

💠 If I have to make a deposit, how can I do this and is there a fee?

Making a deposit should be a simple process at any UK casino. Just click on ‘Deposit’ and follow the on-screen prompts to add your payment details and select the amount. Before confirming your deposit, any applied fees should be clearly stated. If there is any confusion about extra charges on your deposit, then contact the casino right away to get some answers.

How Online Casinos Are Regulated in the UK

All casinos operating in the UK market must be licensed and regulated by the Gambling Commission. Any casino without a GC licence isn’t permitted to provide its services to players within the UK territory.

The regulations which they impose for UK casinos are designed to protect players from both fraud and gambling issues. For example, to play at a UK casino, you must be 18 years of age or older and cannot now use a credit card to fund your casino account. This even applies when using a 3rd party payment provider, such as an e-wallet. The GC also oversees strict regulation around the promotion and marketing of gambling in the UK, which is one of the world’s largest domestic markets.

There are also specific rules which apply to individual casino games such as the ban on buying bonus features within a game. It’s no longer possible to spend extra funds to gain any sort of advantage like buying the bonus round instead of triggering it with 3 scatters.

Here at Slotsia, we take great care to only recommend GC licensed casinos which are as safe as possible for you to play at. However, it is always down to you as a player to check over any casino you want to play at and ensure it is safe to do so.

We only recommend gaming sites which pass our stringent testing criteria and are officially licensed by the Gambling Commission.

In order to identify a secure, reputable casino, players should first and foremost check their licence. You can find a casino’s UK licence number displayed in their footer, along with the GC logo. Alternatively, you can crosscheck the casino operator’s name with the Gambling Commission’s register. Secondly, players should ensure that the payment options available on the casino are secure.

This really depends on which style of bonus you want to claim. If you love slot games, then look for casinos with bumper free spins offers. If you don’t want to be tied down to one or two games, then bonus cash match offers might be the way to go. Remember to always check the wagering requirements and avoid anything north of forty times (40x) which is considered to be very high.

Yes, you can, but there’s never a guaranteed win. Some players choose to play high RTP games for a better chance to win. However, it’s important to remember that winning at casino games is all down to luck. Always aim to keep things fun and play for entertainment purposes only.

There are casino games out there to suit pretty much any taste and budget, so it’s totally down to your playing preferences. If you enjoy fruit machine style games, then there are an endless amount of slots to choose from. For more advanced players there are plenty of slot games with more complex bonus rounds and special features contained within. If you enjoy the buzz of a live casino table game, then pick from the hundreds of streams featuring poker, blackjack, roulette and much more. The choice is yours!
