How To Play Casino Games Online
Getting started at an online casino to play your favourite game is extremely straightforward nowadays and you can be up and running in just a few minutes. In order to ensure that you don’t miss anything, we have compiled a short step-by-step guide to help you on your way.
All of our online casino reviews contain information relating to any introductory bonuses or offers, the range of available games, customer support options and much, much more.
You’ll find a registration button towards the top of the main lobby. Simply click it, follow any on-screen instructions and enter all of the required details to get started.
First, you’ll want to navigate to the banking/cashier page to begin the process. Once there, you’ll notice a wide range of leading payment methods that will enable you to instantly credit your account.
Whether you’ve had a run of good luck or you’ve simply decided to call it quits, you can request a withdrawal using the same range of available payment methods. Head to the banking/cashier section to initiate the transaction.
How We Rate Our Casinos
At Slotsia we don’t just recommend any old casino – each brand listed on our site has been thoroughly checked to ensure that it fits the exact standards of our experts. In case you are curious, these are the criteria that we take into consideration:
However, whilst a large slot library is a great foundation, there’s a reason that quality often outshines quantity. We, like yourselves, want slots that keep us entertained and coming back for more, which is why we look for the innovative skills of certain leading game providers. Top brands such as Microgaming, Red Tiger Gaming and Play’n GO, amongst many others, consistently release top-tier games on a regular basis. So whenever we come across a site that utilises a combination of these products it’s likely to earn a much higher rating than those that don’t.
However, we also gauge a casino’s rating on how far their portfolio reaches. Those that also deliver an extensive live casino catalogue along with other genres such as poker, scratchcards and jackpot games are much more likely to rank higher on our rating scale.
That being said, it’s also important to take note of any potential deposit limits and/or fees. Here, transparency is key. The most trustworthy casinos present this information upfront so that players aren’t hit with any unexpected charges or issues when making a deposit. Equally, it’s imperative that information pertaining to expected withdrawal times is conveniently displayed, not tucked away inside a wall of text within the terms and conditions. After all, it’s your money and you should know when it’s likely to reach your account.
7 Tips for Finding the Highest Paying Online Casino Games
Landing a huge win is an exhilarating experience; within seconds you can go from casually playing to seeing a dramatic increase in your account balance. Of course, there are never any guarantees when it comes to gambling online and you won’t always secure a payout. However, if you consider the following tips before playing, you may be able to increase your chances of winning.
1 – Compare different game types
If you’re looking to secure a large payout, it’s important that you analyse each genre of casino game to determine the best possible route to riches. In general, online slots tend to offer the greatest potential returns in relation to your stake – a £0.20 spin could net you a win worth well over 100,000x your bet (£20,000) on certain games in rare instances. This avenue opens up immense possibilities for players of any type of bankroll, of course. The downside is that these types of payouts are incredibly hard to come by.
High-stakes table games are also an option if you don’t mind the inherent risks involved.
You may need to take a seat at specifically tailored high roller tables and you’ll have to lay down a substantial wager to see equally sizeable returns, but if Lady Luck is on your side you could walk away with huge profits within an instant.
2 – Check RTP percentages and the House Edge
A slot’s RTP (Return to player) estimates your theoretical returns over the course of an extended play session. It’s shown as a value out of 100% and the higher it is, the better. Of course, you will see slight deviations during your average playtime; some that result in a favourable outcome and others that are much less beneficial.
Likewise, table games and their respective variants display a house edge. In this case, the lower it is, the better as this is the mathematical advantage the casino has against you during any given game round. Ultimately, if your goal is to maximise your chances of winning, you’ll want to select any type of game that offers either a high RTP value (somewhere in the region of 96%+) or a low house edge.
3 – Understand game volatility
When it comes to figuring out a slot’s overall payout potential several important factors create its overall math model. The first of which is its RTP, which we touched upon previously, but another major aspect is the game’s volatility. This refers to how often you can expect any given game to payout.
Each slot’s volatility is rated on a variance scale ranging from low to high, or extremely high in very specific cases. Essentially, low volatility slot gameplay tends to favour paying modest wins regularly, whereas high volatility games often pay less frequently but the wins are much more valuable. Generally, low volatility slots are ideal for new or casual players who are looking to keep their bankroll ticking over as there’s much less risk of long winless streaks. Conversely, high volatility slots are often the go-to for regular players due to their ability to deliver enormous payouts – the main downside is that it can be quite some time before you see any respectable returns.
4 – Utilisie bonuses wherever possible
Making use of online casino bonuses is another great way to be in with a chance of landing big payouts.
The simple act of signing up to a casino as a new player can unlock special offers that you can use to play various games. It’s not only new customers who can benefit though, returning players are often able to make use of regular deposit bonuses, free spins and other promotions to extend their playing session. Of course, these bonuses won’t improve a game’s math model, but they will enable you to play for longer, thus giving you even more opportunities to land a winning spin and a potentially huge payout.
5 – Look at the game’s maximum payout potential
When it comes to looking for the highest paying casino games, you’ll also need to consider the maximum payout each title can award on any given spin or game round. Online slots often display this as a multiplied value relating to your stake: for example 5,000x. Therefore, if you were to wager £0.20 per spin and successfully landed the max win in the example mentioned above, you’d be looking at a return of £1,000. However, if you were to up the ante and set your bet at £1 per spin, the same win would yield a £5,000 payout. Whilst that would be a staggering result, there are plenty of slot games that go above and beyond when it comes to big win potential, which leads us nicely on to our next tip.
6 – Search for certain game providers
Certain names within the industry have become synonymous with launching casino games that deliver immense payout potential. Nolimit City’s slot portfolio boasts a staggering range of titles that offer prizes worth well over 40,000x your stake, the largest of which, San Quentin xWays, offers a staggering 150,000x maximum win. Elsewhere, industry favourites NetEnt and Relax Gaming have also earned similar reputations courtesy of the immensely popular Dead or Alive 2 and Money Train 2 slots. Therefore, it’s always worth taking a look at their respective catalogues before deciding upon which game to play.
7 – Do your research
Finally, it’s always worth spending some time brushing up on game information before playing.
Although venturing into the unknown can be an exhilarating experience, we strongly advise you to check out our slot reviews before putting your hard-earned cash on the line.
We cover all of the important details relating to game volatility, RTP, maximum payout potential and features in an unbiased manner, to provide you with the right tools you’ll need to make an informed decision.
Online Casinos Without Registration
It may seem strange, but certain online casinos don’t require you to create an account before you’re able to start playing. These are often referred to as no-account casinos and they offer certain advantages over regular iGaming sites.
Unsurprisingly, the primary attraction of no account casinos is that there’s no need to sign up. As soon as you visit the site you can instantly make a deposit and start playing. Of course, that may raise certain concerns about financial security for some players – at the end of the day, how does the casino keep track of how much remains in your casino balance? Well, as opposed to utilising personal account information to separate individual players, no account casinos rely on your banking details, which, in most cases, is related to your online banking service to provide up-to-date information. Additionally, they may also use your IP address or other techniques as a means of identification.
It must be said though these sites are relatively rare in the UK. However, if you’re planning on trying them out be sure to keep an eye open at Slotsia for our top recommendations!
Online Casinos Bonuses
Online casinos usually offer a range of bonuses to incentivise new players to join and existing customers to keep coming back for more. These promotions can be a great source of additional funds and you’ll find that they come in a wide range of formats, as you’ll discover throughout our casino bonuses page. Below, you’ll also find a brief overview of what each offer typically entails:
- Welcome bonus: These offers grant new players additional funds to play with but do require an initial deposit to activate.
- Free spins: Free spins allow you to play eligible slot games for free. These can be standalone offers but also sometimes come in conjunction with welcome bonuses.
- No deposit bonus: No deposit bonuses grant free cash or several free spins for players to use on eligible games. However, due to their valuable nature, they’re often much harder to come by.
- No wagering bonus: There are no wagering requirements attached to this particular offer – whatever you win from these bonuses is yours to freely withdraw.
- Cashback bonus: These offers usually return a percentage of your total losses over a specified period of play.
Online Mobile Casinos
Mobile compatibility is an integral component of any successful modern casino. Nowadays, players not only want the ability to access their favourite games via smartphone or tablet but they also demand the same great selection of games and overall experience.
It’s pivotal that leading desktop casinos also develop mobile browser-friendly versions and/or dedicated apps for players who prefer to gamble on the go.
Thankfully, the majority of online casinos have adapted alongside the latest technological advancements, giving you plenty of great options. You can compare all of Slotsia’s top recommended sites by checking out our mobile casinos page. There, you’ll find everything you’ll need to get up and running when playing on the smaller screen.
Whilst online casinos are a great source of entertainment and potentially life-changing wins, each site has a duty to ensure players and their sensitive details are secure at all times. That’s why you might have come across certain verification checks when signing up, making a deposit or requesting a withdrawal. It’s not the casino trying to cheat you out of your well-earned winnings, it’s more to safeguard each transaction and prevent any fraudulent activity. Below, we’ll take a look at measures casinos put in place, what they mean and you can meet the necessary requirements.
Why Casinos Asks for Documents
At some point, all players who visit legitimate online casinos are required to provide certain documentation. The question is: why? Ultimately, it boils down to security and something known as the Know Your Customer (KYC) process. This involves stringent scrutiny of a player’s identity to confirm they are who they say they are.
In essence, casinos have to know who their players are, where they’re playing from and that the payment methods they’re using are theirs. Otherwise, the sites would not be able to provide a secure environment in which players can gamble.
Know Your Customer Checks
There is also a myriad of different reasons sites request proof of identity. Primarily though, it’s a legal obligation. Licensed casinos must comply with specific regulations in order to operate to prevent any fraudulent activity or money laundering. It’s also to ensure that players are of legal age to gamble. Since registration details can be faked, the only surefire way to confirm someone’s age is to request ID verification.
Other concerns relate to potential bonus abuse and the prevention of problem gambling. Bonus offers are something of an investment on the casino’s part. They’re used to attract players, of course, but they do cost sites a lot of money. So, if players were able to circumnavigate the single-use per household rule it could result in major losses for the casino, hence the need for personal ID checks. Likewise, online casinos have a duty of care to their players. If a customer shows unsustainable gambling patterns, KYC checks can help prevent future losses by restricting access.
Different Types of Documents used for Verification
A standard verification process usually requires several things to verify your account: proof of identity, proof of address and proof of payment method.
Proof of ID
To prove your identity, you’ll need to provide a copy of any of the following documents:
- Driver’s licence
- Government-issued photo ID card
Proof of Address
Again, you’ll need photocopies of any of the following legitimate documents to prove where you live:
- Any recent utility bill
- A recent bank statement
- Government-issued document containing your address
Proof of Payment Methods
Most casinos will offer a variety of card payment methods, along with instant banking and eWallet solutions. However, you will need to verify each method before it can be used to deposit funds
- Debit card: You must show proof of the first 6 and last 4 digits, your name and expiry date. You need to show proof that the card is signed and must also cover the 3 digit CVC code on the back.
- eWallet: Verification is simple, simply provide a screenshot that displays your email, account number/ID and your name.
- Bank transfer: Provide a bank statement or a screenshot from your online account showing your name and account details.
Whenever you undergo a verification process, most casinos will allow you to follow the current status of your verification; you’ll be able to see whether your documents have been approved, declined or are still pending.
In most cases, the process will take between 1-3 days but if any problems arise the casino will quickly notify you so that you can make any necessary amendments.
Summary of the Know Your Customer Process
The Know Your Customer process is mandatory at UKGC-licensed casinos. However, it can be completed as quickly as possible as long as you follow certain instructions and provide clear photocopies or screenshots of the required documentation.
Its purpose is to ensure the safety and security of each player, along with the operator (casino) to which you’re entrusting your personal and financial details. KYC is also in place to prevent ID theft, fraudulent activity and underage gambling.
Casino Customer Support
There may come a time that you need assistance when gambling online. Thankfully, modern casinos usually offer a comprehensive support service, which is on hand 24/7 to resolve any of your potential queries or concerns. Should you ever need to get in touch with a customer support representative, you can look below to discover how to do so and what options are typically available.
How to contact support
Most casinos similarly display their available support options. There’s usually a dedicated support page that you can access directly from the main lobby; you merely have to click the provided link and you’ll be redirected to the active support channels.
Additionally, there’s often a live chat support bubble permanently located in one of the corners of the screen. If you prefer to use this option, click the button and a representative should be on hand to help resolve any issues.
Types of support channels (email, phone etc)
- Live Chat: This is best used for matters of an urgent nature, which require support in real-time. The response times are often amongst the quickest, provided a representative is available.
- Email: If your concern is of a more complicated nature, you may be better served by sending an email. The estimated response times are often somewhat longer than that of live chat queries but you can usually expect a reply within 24 hours.
- Telephone: Some casinos provide a contact number so that you can speak directly with a member of customer support. However, this is usually only available within specified hours.
- Support Ticket: Within the casino’s support page there may be a support ticket form available. This removes any necessity for a personal email; you merely enter the valid information and any response will be sent via a personal account message.
Whilst we aim to recommend the best casinos and games, it’s also our duty to promote responsible gambling. That’s why we’ve created a page dedicated to the subject. There you’ll find plenty of useful information that you can use to help prevent problem gambling, and set personal limits along with a section devoted to separating certain gambling myths from the facts.
Always remember that legitimate UK casinos will always have tools in place that will allow you to keep tight control over your spending. We strongly advise that you make use of the provided deposit limits and timeout features so that playing at an online casino remains a source of entertainment.
However, should you ever decide that the time has come to quit you should be aware of how to close your account. You may be able to set a permanent timeout from within your account settings but you may also need to contact support in order to confirm a complete account closure.
