What is a Casino Bonus?

A casino bonus is a special promotion offered by online casinos. They’re usually provided as a way of encouraging players to sign up and deposit, as there’s a lot of competition between online casinos. All casino sites rely on players to make profit and the more players they have, the better it is for the site. That’s why nearly every online casino offers some kind of bonus, because they want new customers to sign up and play. Online casino bonuses are prevalent at casinos throughout the world, but you can find some of the best bonuses in the UK. The most common slot game that casinos offer free spins for is our game Starburst.

There are loads of different bonuses out there which each have different ways to claim them and different advantages and disadvantages. Depending on the site you’re playing at, some bonuses might be a lot more common than others. The type of bonus you prefer will depend on your own preferences, but the terms will also have a big impact. All bonuses come with specific terms and conditions to prevent players from essentially collecting free money from the casino. You can still win real cash using your bonus, but certain restrictions make it a little harder.

The best online casino bonuses are easy to claim, simple to use, and have few restrictions. Whether you’re into table casino games, online slots, live games or any other type of casino game, there’s a great bonus out there waiting for you to claim it. Use your bonus to try out new games, test out the features of a casino, or just to dip your toe into the water of online casinos for the first time. 

Types of Casino Bonus

Generally, all casino bonuses can be split into two distinct categories: the welcome bonus and the current player bonus. Both categories contain similar types of bonus, although welcome bonuses will usually be slightly bigger. Each type of bonus will have its own restrictions and specific ways to claim and use the bonus, so always check the terms before you sign up. 

Welcome Bonus

A welcome bonus is a special type of offer that online casinos provide to new players. This means you’ll only be able to claim this offer if you’re signing up to the site for the first time, but don’t worry, because nearly all casinos offer some type of welcome bonus. Even if you’re already a member at a online casino, you can still sign up to another site and claim a new welcome bonus.

Welcome bonuses can often be a mix of different bonuses, including no deposit bonuses, matched deposits, free spins, or cashback bonuses. The most common type of welcome bonus is the matched deposit and free spins offer. To claim a welcome offer, you simply need to click on one of our links, register, and make your first deposit. Your account will then be credited with your bonus to use how you like (within the terms of the promotion of course). 

Matched Deposit Bonus

A matched deposit bonus is one of the most common types of online casino bonus offered by casinos. For this bonus, you’ll need to make your first deposit over the minimum amount in order to qualify. Matched deposit bonuses are normally offered as a welcome bonus to new players, but some casinos also offer them to current players too. Matched deposit offers will usually boost the amount you have to play with from your first deposit. They’ll sometimes be split into separate parts and also provide you with multiple bonuses for several deposits. 

As an example, you might see a bonus that tells you you’ll receive a 100% matched deposit on your first deposit up to $500. This means that any amount of cash you deposit into your account for your first deposit will be matched 100%. You can deposit up to $500 and you’ll receive another $500 in bonus cash to use, that will give you $1000 in your account to play with. You can still deposit more than $500 if you want to, it just won’t be matched, so the maximum you can claim is capped at $500.

No Deposit Bonus

No deposit casino bonuses are one of the most popular types of bonus for casino players all over the world. Rather than needing to make a deposit before you can play, this bonus lets you simply sign up and start playing risk-free. Once you’ve signed up and claimed the bonus, it will be added to your account with no deposit required, compared to a regular casino, no bonus deposit where you only have the deposited amount to play with.

These bonuses are typically smaller than matched deposit bonuses and come with more restrictions, but they’re an excellent way for players to try out a new casino without needing to use their own cash. Once you’ve played through the bonus funds, you’ll normally need to make a deposit before you can withdraw it, but by this point, you should have a good idea of whether you like the casino enough to keep playing. 

Free Spins Bonus

Free spins can be found as part of a welcome package alongside matched deposit offers, no deposit bonuses, or simply by themselves. Free spins are also often provided regularly by top UK casinos to encourage players to try out new games, to welcome players back after being away or as a reward for completing challenges on the site. 

Free spins give you a certain number of spins at selected online slots. These could be NetEnt spins or for any other type of online slot. The stake for each spin will be capped at a certain amount and some free spins also have a maximum win cap and usually a wagering requirement.

Reload Bonus

A reload bonus gives you a certain percentage on your deposit, similar to a matched deposit bonus. Reload bonuses are awarded to current or returning players though and tend to be smaller than matched deposits. As an example, you might receive an email telling you that you can claim a 50% reload bonus up to $100 on your next deposit of $50 or more. If you want to claim the maximum bonus, you’ll need to deposit $200, giving you $300 in bonus funds to play with. 

Some casinos offer regular reload bonuses to current players as a way of incentivising regular play. These are a great offer and an excellent way to maximise the amount of money you have to play with. Make sure to always claim your weekly or monthly reload bonuses if they’re available. 

Cashback Bonus

Some casinos offer a slightly different form of bonus, the cashback offer. These are slightly rarer than matched deposits and free spins but can still be found at several top UK casinos. With this bonus, you can claim a certain amount back on any losses you make. This gives you a way of playing with relatively little risk and is a perfect offer for new players who are still unsure of the risk that comes with casino games.

As an example, a casino might offer you 50% cashback on any losses you make up to $300. If you happened to lose $600 while playing during the specified time, you’d receive $300 back in bonus funds. While these bonuses are great, a lot of players still prefer the matched deposit bonus as they’re easier to claim. 

VIP/Loyalty Bonus

Finally, most online casinos in the UK also offer a loyalty or VIP program. Loyalty programs incentivise you to play regularly and reward players with bonuses for regular play. You’ll be entered into the loyalty scheme when you sign up or opt-in and will gain points each time you wager money on a game. Points will depend on the casino you’re playing at but you can eventually exchange them for free spins, bonus funds, cash and other rewards.

VIP programs are invite-only in the UK and provided you bet a certain amount regularly, you’ll be invited in. These schemes give players the chance to receive exclusive bonus deals, extra free spins, invitations to special events, a personalised gaming experience and much more. 

Live Bonus

Live casino games are a brand new, exciting way to experience the thrill of the casino. While normal online casino games have you playing against a computer, live casino games feature real dealers and hosts. These dealers are live streamed from a studio, where they’ll shuffle and deal cards, spin the wheel and interact with you as you play. 

Lots of online casinos that offer live casino games will provide live casino bonuses. These are exclusive to live casino games and give you a set amount of bonus funds or free bets to play with. If you love table games like Blackjack, Roulette and others, you’ll no doubt enjoy the excitement of live casino games, which bridge the gap between online casinos and their real-life counterparts. 

Wager Free Bonus

The majority of bonuses come with wagering requirements which mean you’ll need to play through your bonus a certain number of times before you can withdraw it. These are often frustrating for casino players, but they’re quite common. 

If you’re sick of casino wagering requirements, you’ll be interested in wager free bonuses. These provide you with a set bonus that you won’t have to playthrough before you can withdraw. The downside of these are that most will come with another restriction like a maximum winning cap. Remember that nothing is ever really free and all casino bonuses come with restrictions on how you can use them.

Casino Bonus Terms and Conditions

Every bonus offer comes with a set of terms and conditions which will affect how you can use it, what games you can play and when you can withdraw it. Bonuses are a great way to win some extra cash, but online casinos don’t just give away money for free. There are always restrictions to prevent players from simply signing up, collecting the bonus, withdrawing it and never signing in again.

Different casinos will use different bonus terms but we’ve listed some of the most common terms and restrictions below. We always recommend that you read through the terms carefully before you sign up and consider whether the bonus is still worth it. Some bonus offers look great initially, but once you read the terms you may realise it’s hard to claim and cash out any winnings. 

Wagering Requirements

Nearly every online bonus offer will include some form of wagering requirement. These are a special restriction that requires you to play through your bonus funds a certain number of times before you can make a withdrawal. The casino imposes this rule to stop players claiming a bonus and then withdrawing it straight away.

The exact wagering requirements will vary depending on the casino you’re playing at and the size of the bonus. Typically, it will be between 20x and 35x. As an example, if you receive a $100 bonus with a 20x wagering requirement, you’ll need to wager a total of $2000 when using your bonus funds. This may seem like a lot but it can generally be completed fairly quickly. Most casinos will also include a time limit alongside the wagering requirement. You’ll have to reach the requirement within a set amount of time or else your bonus and any winnings you made from it will expire. 

Some casino bonuses will require you to wager your deposit, the bonus and the winnings while others only ask that you wager the bonus and any winnings a set number of times. This will depend on the casino you’re playing at, so check the full terms and wagering requirements carefully before you sign up. Bigger bonuses might have wagering requirements of up to 60x which are much more difficult for casual players to reach. Always evaluate the wagering requirements and think about whether you can realistically attain them. 

Maximum Win Cap

In some cases, your bonus might come with a maximum win cap or maximum withdrawal. This limits the amount you can win using your bonus and prevents you from withdrawing over the limit. This type of restriction is less common than wagering requirements but will often be used on no deposit bonuses or bonuses that don’t require wagering. 

As an example, let’s say a casino offers you 200 free spins with a maximum win cap of $200. When it comes to withdrawing your winnings, the maximum amount you’ll be able to withdraw will be $200. If you win more than that with your spins, you won’t be able to withdraw it and the extra cash will be removed from your account in most cases. These win caps can sometimes be annoying to deal with, particularly if they feature a low win cap. Check the terms carefully before you claim your bonus to see if there’s a maximum win and decide whether the bonus is worth it for you. 

Restricted Games

A lot of casinos may place a restriction on which games you can play using your bonus. This doesn’t apply to every bonus offer, but some, mostly free spins, will only be valid for specific games. Some casinos offer bonuses specific to a software provider, such as a NetEnt bonus, that can only be used to play NetEnt games. Others will limit the bonus to brand new games or games that are exclusive to the casino.

Game restrictions often also apply to wagering requirements. You might find that not all games contribute equally to your wagering. For example, slots may contribute 100% while table games such as Blackjack and Roulette only count 50%. This means that if you use your bonus to play table games, you’ll need to wager twice as much to complete the requirements. This doesn’t apply to every bonus, but it can make unlocking the full potential of your bonus a little more difficult. Check the terms and conditions carefully to look out for any game restrictions and see whether different games have different weightings towards the wagering requirements. 

Payment Methods

Most online casinos let you choose from a lot of different payment methods when it comes to making deposits and withdrawals. These allow you to make simple and fast payments, and the more options available, the better for the players. However, while most online casinos allow you to choose between payment methods, some payment methods may mean you miss out on a bonus. 

Debit card payments will usually always unlock your bonus funds, it’s only certain eWallet payments that may not be accepted. As always, read through all of the terms carefully before you sign up to make sure that your preferred payment method is supported. 

How to Choose the Perfect Casino Bonus

There are hundreds of fantastic online casinos available for UK players and all of these provide loads of great bonuses. With so much variety, a lot of new players are sometimes confused over which bonus to choose. That’s why we’ve listed the best casino bonuses in UK at the top of the page. Check out our list to find something you like. 

If you’re still unsure, there are a few things to consider when choosing an online casino bonus offer. You’ll want to make sure that the bonus you pick is going to be simple to claim, fun to play and gives you the potential to win real cash. Follow our steps below to choose the perfect bonus for you. 

1. Choose from a top UK casino

There are loads of great online casinos to choose from if you’re in the UK. Each will have different games, features and bonuses and you’ll need to pick the one that suits you best. Just as it’s hard to choose a good bonus, picking a good casino can also be hard, especially because there are so many great ones available! You can look at our list of top casinos for reference but try and choose a site that’s licenced in the UK, has a great selection of different games and makes withdrawals fast and simple. Use your choice of casinos to influence your final decision over which bonus you choose. 

2. Think about the kind of games you enjoy

Bonuses are often closely tied to certain games. For example, free spins can only be used on video slots, live casino bonuses are tied to live table games and there are sometimes even restrictions about the specific game you can play. Think about the kind of games you enjoy playing at the casino and what you’d most like to use your bonus on. If you’re not a fan of slots, a bonus that promises lots of free spins isn’t going to be as appealing to you as a smaller bonus that allows you to play your favourite game. Your main goal is to use your bonus to have fun, so you’ll want a bonus that’s going to give you a chance to enjoy the type of games you love to play. 

3. Check the terms of the bonus

It’s always important to go over the terms of your bonus carefully and ensure you understand everything. Most casino bonuses include fairly stringent rules and restrictions on their use. Failing to follow these rules can result in the loss of your bonus and any winnings you’ve made from it. Check that the bonus terms are reasonable by comparing them to the terms of our top UK casino bonus deals. Wagering requirements should be relatively low and there should be an easy way for you to complete any restrictions within the time limit provided. 

4. Go for quality over quantity

Lots of casinos offer big bonuses in the hope of attracting players and getting them to sign up. In many cases, however, these bonuses come with a lot of extra restrictions which can be difficult for players to get value out of them. Sometimes, going for the smaller option with less restrictions is better. However, this will come down to personal preference. If you’re capable of completing the big wagering requirement within a short amount of time, you can still claim that big bonus. Look for bonuses that are appropriate for your level as a player, if you only play occasionally, you probably don’t need a huge matched deposit bonus and won’t be able to complete the requirements before it expires. If you’re used to playing casino games every day, you have a much better chance of getting value out of the bigger bonus. 

How to Claim Your Casino Bonus Online

Now you know all about casino bonuses and how to choose them, all that’s left is to sign up and claim your bonus! Before you start, you’ll want to know exactly how to sign up to ensure you don’t miss out on potential bonus funds. Most casinos will require you to follow certain steps and activate your account to claim your reward. Below are the main steps any online casino requires from its players before they provide the bonus funds. Follow these steps carefully to claim your bonus and maximise your fun at the casino.

1. Follow Our Link

On this page we’ve included links to loads of top UK casino bonuses. You can click on these links to be taken directly to the casino where once you sign up, the bonus will be yours. Normally, you might need to opt in or use a promo code but with our bonus links, the bonus will already be active when you click on the link and sign up. This is the easiest way to guarantee you get your hands on the best casino bonus possible.

2. Sign Up

Once you’re loaded up the casino page, you’ll need to register for a new account. Use the registration form to fill in your details, taking care to get these correct. You’ll need to verify your details later to make a withdrawal, which is why the accuracy of your information is so important. If your details don’t match up with your ID, you may not be able to withdraw your funds. If your details change for any reason, you should be able to change them later on. Speak to the customer support team if you’re unsure about any part of the registration process. 

3. Enter a Bonus Code if Needed

Some casino bonuses require you to enter a bonus code when you first sign up. If required, there will be a separate box on the registration form for you to enter the code. If you use our links, you won’t need any code and can instantly unlock the bonus just by signing up and making your deposit. Bonus codes can expire, so make sure the code you have is a recent one.

4. Make the Qualifying Deposit

Unless you’re claiming a no deposit bonus, you’ll need to make a deposit to unlock your bonus. All casinos will require you to make a minimum deposit to either withdraw or unlock your bonus. The minimum deposit will vary depending on the casino but it will usually be between $10 and $50. Be sure to use an accepted payment type to make the deposit, otherwise it won’t count towards unlocking the bonus. 

5. Enjoy Your Bonus!

The last thing left to do is to make the most of your bonus funds and have fun! Use it to play your favourite games and try to get the wagering terms completed as quickly as possible. You can also use your bonus to try out some new games and give yourself a better idea of how the casino works. There are a lot of fantastic games out there for you to enjoy, we suggest using your bonus to make the most of the games available. 

Win Real Cash With Your Bonuses

A casino bonus is a great way to try out a new casino, new game or simply to have fun. Shrewd online casino players also use them as a way to make some extra cash. Provided you know the terms and restrictions of a bonus and what it means, you should be able to spot when an online casino offers a great deal. Look out for wager free spins or other types of bonuses that have low wagering requirements. Make sure that the game you like to play counts towards wagering, as this will help you unlock the bonus and withdraw it as cash.

Once you find a good bonus that suits your needs, you can use it as a way to make some cash. Try to reach the wagering requirements as quickly as possible and make the most of highly volatile games, as these will give bigger payouts. If your bonus has a maximum win cap, low volatility slot games are a better option, as you’ll be able to win smaller amounts more consistently. 

Make the most of your bonus by beating the wagering requirement quickly and then either withdrawing your winnings or using them to keep on winning at the casino. Once your wagering requirements are complete, you can withdraw your bonus as cash and use it however you want. 

Casino Bonus FAQ

We’ve covered just about everything to do with bonuses in our guide, but if you still have questions, we’ve got answers. Below are some of the commonly asked questions about bonuses and their answers.

At UK casinos, all bonuses can be cancelled if you no longer wish to play. If you feel like you want to cancel your bonus for whatever reason, simply log in to your account and go to your account details. You can also cancel your bonus quickly by contacting customer support. Most online casinos will also cancel your bonus if you make a withdrawal before completing the wagering requirements. 
Yes, all bonuses give you the opportunity to win real cash, one of the reasons why they’re so popular. Of course, there are sometimes restrictions on how much you can win and most casinos will also require you to wager your bonus and any winnings a certain number of times before you can withdraw your winnings as cash. Look out for the terms of the bonus when you first claim it to see if there is a maximum win cap and read through the wagering instructions. 
In the UK, all online casinos must have a licence from the UK Gambling Commission (UKGC) to allow UK players to sign up. The UKGC ensures that the online casino is fair and treats players well. All games must have their return to player rates published to ensure transparency and help players make an informed decision over which games to play. Online casino games are based on luck and there’s nothing the casino can do to influence the odds. 
Casino bonus offers change a lot so it’s hard to say what the biggest bonus right now is. You can take a look at some of the big bonus offers at the top of this page to get an idea of what sort of bonuses are available. There are loads of big free spins offers, huge matched deposit bonuses and more on our page, all available for players from the UK. 
Modern online casinos are all optimised for mobile play, meaning you can enjoy all your favourite games on your mobile phone. Connecting to your online casino on your mobile is as simple as loading the site in your browser and signing in. Some sites also provide an app which provides a smoother gaming experience for players. As with the main site, you can use your casino bonus when you play on your mobile, some sites even offer a special bonus for mobile players. 
Yes, the majority of online casino bonuses will have an expirations date. Unfortunately, that means if you have an old casino bonus you haven’t used in a while, it’s probably already gone. Most casinos will give you at least a week to use your bonus, but it does vary depending on the site. There are some bonuses out there that will only give you 24 hours to use your bonus before it expires. You’ll also need to meet the wagering requirements within a specific amount of time, the bonus and any winnings will expire once the time is up if you didn’t meet the requirements. 
There are no real downsides to casino promotions. They provide an excellent way for new players to try out different games and get used to a new online casino. They’re a lot of fun to use and can also potentially reward you with some big wins. The downsides are the terms and conditions, but most of these are fairly simple and should be easy for players to complete and remember to gamble responsibly.
Some casino offers will require you to enter a bonus code when you sign up. These codes are usually a few letters and a number such as BONUS1 or similar. Not all casinos will require a bonus code and if it’s not mentioned in the terms of the bonus, it’s not needed. To use a bonus code, you simply have to copy the code and enter it into the box when signing up or making a deposit. The claiming process will always be  explained in the terms of the bonus so you don’t need to worry about potentially missing a bonus code. 
There could be lots of different reasons why your friend got a bonus but you didn’t. Your friend might be signing up to the casino for the first time and claiming a welcome bonus that you already received when you first signed up. Your friend could be a member of the loyalty program or VIP scheme and is receiving a special bonus through this. Alternatively, your friend might have completed steps to sign up for the bonsu which you missed. If you’re unsure, check with the casino customer support. 
Bonuses will expire after a certain length of time, meaning you might have simply run out of time. Most casinos will also invalidate your bonus if you make a withdrawal before you’ve completed the wagering terms. Sometimes, a casino will also forfeit your bonus if you’ve been found to be misusing the terms of the offer. If you’re not sure why your bonus was removed, check with the customer support team of the casino.
