How Online Casino Bonuses Work

Online casino bonuses serve several purposes for both players and operators alike. In essence, they’re designed to attract new players to a site and then retain their custom by offering a wide range of incentives.

As a player, you can earn rewards for completing the simplest of actions, ranging from signing up as a new customer to making a real money deposit. Once you fulfil the necessary requirements, your bonus is unlocked and you’ll receive the respective rewards, whether they be in the form of bonus funds, free spins or cold, hard cash.

However, it’s worth noting that certain terms and conditions usually apply to these offers, which we cover in further detail in the section below.

What You Need To Know Before Claiming a Bonus

Although casino bonuses can initially appear to be vastly rewarding, there are certain factors you must first consider. You should never be swayed by a flashy offer just because it promises the world; you should take the time to read through the terms and conditions as these are what determine the offer’s true value and help separate the genuine bonuses from those that are inherently predatory.

Of course, reading through the fine print can be a tiresome task and if you don’t really know what you’re looking for it can be a fruitless endeavour. That’s why, below, you’ll find our list of the most important T&Cs that you’ll want to look out for.

Wagering requirements are perhaps the most common obstacle you’ll face when presented with a casino bonus. This particular T&C refers to the number of times you must wager your total bonus amount before the casino converts the funds into real money, making it eligible for withdrawal.
Wagering requirements vary between sites and from one bonus to the next. However, you ideally want to find an offer that lists a playthrough condition of 35x or less, anything higher can quickly become unattainable, as we highlight in the examples below.

Example #1 – 35x wagering requirement:

Say you made use of a deposit bonus to earn an additional £100 and a 35x wagering requirement applied to the bonus funds. You would need to wager a total of £3,500 before any remaining funds become eligible for withdrawal – (£100 [bonus] x 35 [wagering]).

Example #2 – 60x wagering requirement:

By using the same example as above, but this time with a 60x wagering requirement, you can see how much more difficult it would be to meet the T&Cs. This time, you’d need to wager a total of £6,000 before you can request a withdrawal for anything that remained – (£100 [bonus] x 60 [wagering]).

As you can see, standard wagering requirements are tricky enough but if you throw increased demands into the mix it can make the T&Cs insurmountable.
Although the wagering requirements tend to be the most pivotal aspect of any bonus, several other terms and conditions can also apply. The potential issue is that newer players may not be aware that these are tucked away within the fine print, often hidden amidst a wall of text somewhere on the site.

In most cases, each offer will contain a link that should redirect you to the necessary information. However, on rare occasions, you may have to locate the relevant page yourself – thankfully, you can usually find it towards the bottom of the main lobby. There, you’ll find a detailed, yet somewhat cumbersome, explanation of any additional terms and conditions.
Whenever you claim a casino bonus you need to be aware that it only remains active for a certain amount of time. You have a window in which you must use your free spins or bonus funds and then meet the attached wagering requirements, else you run the risk of forfeiting the offer.

Again, the validity period can differ between bonuses so it’s something you should always check beforehand. As a rule, though, free spins bonuses tend to grant a shorter time frame (1-7 days), whereas deposit bonuses and other offers can last much longer (14-30 days).
Unfortunately, some bonuses apply a cap to your maximum win potential. It can be a source of great frustration if you’re fortunate to land a huge payout, only to discover that you’re ineligible to receive most of it. Thankfully, this isn’t a particularly common T&C but it is one you should always watch out for if you’re looking to maximise your winnings.
It’s important to understand which casino games you’re eligible to play using your bonus. If you claim a free spins bonus, your spins will likely be restricted to a preselected range of online slots. It’s also worth mentioning that they’re often tied to the first game you choose – you can’t use half on one game and the rest on another.

Other bonuses may also be restricted to specific genres such as table games or live casino titles. Knowing what restrictions are in place beforehand can save you a lot of time and hassle in the long run.

Different Types of Casino Bonuses

As you may be aware, online casino bonuses come in all shapes and sizes, covering a wide range of different games. Whatever your tastes or budget may be, you’ll be sure to find something suitable right here at Slotsia and you’ll also find an overview of the most popular offers below.


Welcome bonus

Welcome bonuses are a casino’s primary means of incentivising new players to sign up and deposit. After registering a new account, you’ll likely be eligible to claim a deposit offer upon your first transaction, along with several free spins.

The value of these offers once again varies between sites. However, the standard deposit bonus starts at a 100% match but it isn’t unheard of to find much larger promotions – it’s always a good idea to shop around before you commit!


Free spins

In many cases, free spins are an accompaniment to other bonuses but they can also come as individual promotions. Your spins are usually restricted to either one individual title or a range of preselected games and play out a fixed stake. Remember though, free spins are not transferable between games. Once you select an online slot and start spinning, your bonus is linked to that game.


No Deposit Bonus

Not all casino offers require an upfront payment and if you’re looking to play casino games for free, no deposit bonuses are your best bet. Of course, because you don’t need to make a deposit these promotions are somewhat harder to come by and your winnings are likely subject to a maximum win cap. Nevertheless, if you’re looking for a chance to win free cash we recommend that you take advantage whenever possible.


No Wagering Bonuses

No wagering bonuses, once again, are rather rare. These offers aren’t subject to any playthrough requirements, meaning whatever you win, you get to keep. You won’t need to calculate how many times you need to wager your bonus funds before you’re able to request a withdrawal!



UK online casinos that offer cashback bonuses are becoming increasingly common. Certain sites run occasional promotions that will return a percentage of your net losses during a specified period, so we suggest you opt-in whenever you choose to play. Other casinos, however, offer cashback as part of their loyalty programmes and it’s often the case that the higher your rank is, the more cashback you’ll get!


Bonus Codes

Most casino bonuses are easy to claim; you simply click the advertised link, opt-in and the offer is added to your account. However, some promotions require the use of a bonus code. This is often a case-sensitive, alphanumeric code that you need to input to redeem the respective offer.

Other Types of Casino Bonuses

The offers we’ve listed above are the types of bonuses you’re most likely to come across when playing. Yet others do exist, which can be equally rewarding.

  • Loyalty programmes/points: many top online casinos also provide some sort of loyalty scheme to reward regular players. As you deposit and play for real money, you’ll accrue loyalty points that help you unlock additional perks and prizes.
  • Exclusive bonuses: on rare occasions, certain partnerships and collaborations can result in exclusive bonuses becoming available. These are usually only redeemable via a specific link and are not available to all customers. However, the upside is that they’re often much more valuable than regular offers so whenever you’re eligible to claim one, we suggest you snap it up.
  • High roller match offers: similar to the loyalty schemes that many casinos run, there also exists an equivalent for players who choose to play for much higher stakes. These are often referred to as VIP rewards and come with a much greater value than general bonuses.

Understanding How Online Casino Bonus are Calculated

Almost all online casinos advertise deposit bonuses and their counterparts by way of a percentage match. The number displayed, typically ranging from 50% – 300%, refers to how much of your deposit amount you’ll also receive in the form of bonus funds. The other factor you need to take into consideration is often signified by the term ‘up to’, which indicates the maximum amount the casino will award to a player making a real money deposit.

Granted, this can be rather confusing if you’re unsure as to how these bonuses work. So, to simplify the matter, let’s take a look at an example: 200% deposit match worth up to £400.

Offer ClaimedDeposit AmountBonus AmountTotal Received
A £50 deposit with a 200% deposit match (the remainder of the bonus amount is forfeit)£50£100£150
A £200 deposit with a 200% deposit match (the full bonus amount is met)£200£400£600

How to Choose the Best Online Casino Bonus for UK Players

Now that you have a solid understanding of each of the different types of online casino bonuses, it’s time to figure out how to choose which is best for you. So, the question is: how do you go about doing so?

First of all, you need to decide what games you want to play. That way you’ll be able to narrow down your options to find a suitable bonus. After doing so, we strongly advise that you compare the terms and conditions of the available offers to see which has the most competitive wagering requirements.

Finally, it’s a great idea to check out our casino reviews to gain a full understanding of what each site offers in terms of game selection, security, customer support and whether or not there are any other promotions you can take advantage of.


How to Claim Casino Bonus

You’re at the point where you know which bonus you want to claim. What comes next? How do you actually go about claiming the offer and reaping the potential rewards?

We’re glad to report that very little work is required on your part. All you have to do is follow our simple step-by-step guide below to get in on the action. Note that the exact steps may vary between casinos, but the general gist is as follows:

1Sign Up and Create an Account slotsia

You’re going to need an account to start playing. Therefore, you’ll need to navigate to your chosen casino, locate the registration form and sign up. Again, it’s a straightforward process that should take no longer than a few minutes. You merely need to enter the relevant details as described on each form, click submit and wait for the site to verify your account.

2Choose your Bonus and Check Terms and Conditions slotsia

Always opt-in to your bonus so that you don’t miss out but make sure to familiarise yourself with any applicable T&Cs beforehand. Certain online casinos may require you to accept special welcome offers during the registration process, so keep a close eye out for the respective fields; others may only be available once your new account is up and running.

3Check Which Payment Options You Can Use for your Deposits slotsia

It may be the case that certain payment methods may be excluded from various UK casino bonuses. More often than not you’ll be able to use traditional card payments and assorted eWallets to claim your offer but some of the more recent banking options may be ineligible. Take a look at the site’s accepted payment methods and also the bonus terms and conditions before committing to making a deposit.

4Make your Deposit slotsia

Once you’ve selected a payment method you’ll need to fund your account. To do so head over to the banking/cashier page to initiate the process. Select your preferred option, enter the relevant details and how much you wish to spend and confirm the transaction. If it’s your first time making a deposit you may need to supply additional verification details so that the casino can verify your identity. However, once the site does so, your deposit, along with any additional bonus funds, will appear in your account balance.

5Complete Wagering Requirements slotsia

Now it’s time to choose a game and start meeting those wagering requirements. Still, there are a couple more things you’ll want to bear in mind. First off, you’ll need to understand what wagering contributions are. Certain game genres contribute various amounts towards the overall wagering requirements. This is how much of your stake contributes to the total amount you need to bet. Online slots often contribute 100%, whereas table games, video poker and other genres often contribute less – you can usually find the exact numbers within the T&Cs. Secondly, you’ll need to keep your stake within the maximum bet limit, which is usually around £5 – anything greater will not count towards wagering. Provided you meet these conditions, wagering will progress with each bet you place until you complete the requirement.

6Cash Out The Winnings slotsia

As soon as you’ve completed the attached wagering requirements, which you can normally keep track of by checking your account page, the casino will convert any remaining funds into real money. Then you’re either free to cash out any winnings you’ve earned or continue playing!

Frequently Asked Questions

Ultimately, it depends on what type of casino bonus you want. Welcome offers and sign-up bonuses are limited to first-time depositors and new players. However, as an existing player, you may be eligible to receive various deposit bonuses, free spins and other rewards by checking the casino’s ongoing promotions.

If you’re looking to get the most value out of a bonus, it’s a good idea to check the T&Cs beforehand so that you’re aware of any restrictions and/or wagering requirements. Additionally, we suggest you select offers that permit you to play a wide range of games so you can mix things up from time to time.

Sign-up bonuses and no deposit bonuses tend to be the most popular offers due to the fact they provide free spins or free cash with no deposit required. Of course, they are somewhat rare so if you’re looking for something more common yet equally rewarding no wagering bonuses are a solid alternative.

Nowadays, all top UK casinos are fully mobile compatible. Therefore, whichever offers are available via the desktop site also tend to be available on the smaller screen. Simply navigate to the mobile version of the site or download the casino’s app and follow the same steps to sign up and claim the offer.

At Slotsia we have compiled some of the best bonus codes available at UK casinos. All you need to do is enter the appropriate code to receive the exclusive offer, which could be in the form of a deposit bonus or several free spins to play with.

You may be ineligible to use certain payment methods when claiming casino bonuses. Thankfully though, most sites accept leading card payments and eWallet solutions so you’ll always have a convenient alternative.

This is another term used to describe bonus wagering requirements. In essence, this refers to how many times you must wager your bonus funds, deposit or both before you’re eligible to request a withdrawal.
