What Is a Casino Bonus and How Does It Work?
A casino bonus is any perk or promotion that an online casino gives to you to increase your play time or enjoyment. A casino welcome bonus is a welcome gift for new players, while casino bonuses for existing customers are to reward loyalty.
What Are Casino Bonuses Used For?
Bonuses are a powerful tool for casinos, helping them find new customers and retain existing ones. The good news is, the best casino bonuses can also be a powerful tool for you! A top UK casino bonus can let you play for longer, boost your bankroll, or increase your winning potential.
The Most Common Types of Bonuses
While a great casino welcome bonus is what most players are looking for, there’s lots of variation in sign up bonuses – and even more variation in casino bonuses for existing customers.
Below are all of the different types of promotion you’ll come across on your hunt for the latest casino bonuses.
Deposit Match Bonus
The majority of casino welcome bonuses include a deposit match element. You’ll sometimes see them called match bonuses or matched bonuses.
- These bonuses give you a percentage of your deposit as bonus cash. It’s often 100%, but we’ve seen everything from a 50% match right up to a 500% match.
- If you’re claiming a deposit match bonus as part of a welcome bonus then it might come in several instalments. Sometimes these instalments have a different percentage match.
Example: You claim a welcome bonus with a deposit match of 100% up to £100 on the first instalment, 50% match up to £100 on the second instalment, and a 100% match up to £50 on the third instalment.
Free Spins Bonus
Free spins are one of the most popular types of casino bonus in the UK. You’ll sometimes find them as part of a casino welcome package, or you might find them as a standalone casino offer.
- Free spins bonuses give you a set number of free spins, of a specified amount per spin (often £0.10 to £0.50 per spin).
- They usually work on one specific slot game, but increasingly we’re seeing the best UK casinos offer bonus spins on a small selection of slot games.
Example: You sign up to a casino and deposit £20 to claim 100 free spins on Big Bass Splash.
Reload Bonus
Similar to matched deposit bonuses, reload bonuses reward you for making a deposit, but only if you’re an existing customer. Reload bonuses can come in lots of different forms but the most common are:
- A deposit match reload bonus
- A free spins reload bonus
- A cashback reload bonus
All of the different types require you to make a deposit in order to get your bonus credited. Notably, reload bonuses do tend to be smaller than the best casino welcome bonuses – but are still worth claiming!
Example: Get a 50% deposit match bonus up to £100 when you deposit at least £10.
Casino Cashback
Cashback offers are a great way for casinos to reward loyal players and cushion the impact of losses. They work by giving you back a percentage of your net losses or deposits (often around 10%) over a specific time frame.
While they might not seem like a whole lot of money, cashback deals can be a really effective way to stretch out your bankroll.
Example: Every Monday claim 10% of your live casino losses back from the previous week.
Loyalty Programs
Loyalty programs reward you when you rise up the loyalty ladder ranks. Some casinos use points for every wager, redeemable for prizes and others track overall activity and reward based on play volume or deposit history. Loyalty programs could give you any of the casino bonuses we’ve mentioned above or:
- Prize draws and tournaments
- Exclusive bonuses (with better terms than standard offers)
- Tiered rewards, with greater perks as you climb the ranks
No Wagering Bonus or No Deposit Bonus
There are two types of bonus that almost all of our community (and to be honest, all of our team!) are always on the lookout for: no wagering bonuses, and no deposit bonuses. But, what are they?
- No Wagering Bonus: These bonuses come with no wagering requirements attached. This means that whatever you win is yours to withdraw immediately.
- No Deposit Bonus: This type of casino bonus doesn’t need you to make a deposit to claim it. These are particularly good if you want to try out a new casino for free, or just see if you can win real money without spending your own.
How We Decide Which Casino Bonuses to Recommend
There are lots of top casino bonuses to choose from, so breaking down the list and deciding which ones to recommend is a long process that we take very seriously.
To make our jobs a little bit easier, we invented the FruityMeter™. This clever bit of kit takes the scores that we generate when completing a casino review and gives us one standardised score out of 5. That way you can see which casino bonuses are actually the best with just a quick glance.
To find the scores that we put into the FruityMeter™, we use the bonus review criteria below.
Our Bonus Review Criteria
Bonus Value: The first step is checking how much the bonus is worth, we love to see a big welcome bonus, or a bonus for existing customers that actually adds value. The latest casino offers are only any good if you get a bit of extra bang for your buck for claiming them.
Casino Quality: Next on our list is the quality of the casino. It’s all very well having a massive casino bonus, but if you’ve not got any good games to play it on – there’s no point in claiming it.
Ongoing Bonuses: We love to see generous new customer casino offers, but it’s important that the rewards keep flowing long after you’ve signed up. Regular free spins, cashback, or reload bonuses get points from us.
Licence: It should almost go without saying by now, but we only recommend casinos with a UKGC licence. This ensures your personal and financial data is safe, the casino site is operating legally, and that you always get a fair game.

How to Choose the Right Casino Offer for You
We’ve come up with a selection of the best casino bonuses above – but you don’t need to claim them all at once. Below are some tips on finding the right casino bonus for your style of play.
Think About the Games You Like to Play
If you’re a fan of slots then you’ve got the biggest pick of anyone. Almost all casino bonuses can be used to play slots, especially free spins and deposit match bonuses. However, if you enjoy playing other games consider the following:
- Live Casino Games: Live casino bonuses are harder to come by, but not impossible. They will usually be a deposit match bonus or cashback and tend to come specifically labelled as a live casino bonus.
- Table Games: Bonuses for table games like roulette are a little easier to come by, as it’s often possible to use deposit match bonuses (or casino welcome bonuses) to play them. Just remember to check the game contributions as table games sometimes count less towards wagering requirements.
Consider Your Budget
If you’re betting on a bit of a budget then think about whether you’ll be able to complete the terms in time to withdraw your winnings.
If you’re taking a deposit match bonus, consider claiming only a small part of it. Otherwise, look for no wagering bonuses, to make the most of being able to claim your winnings straight away.
Understanding Wagering Requirements and Other Bonus Terms
All bonuses come with terms attached. Below is a quick explainer of what these casino bonus terms mean. This will let you make an informed decision on whether a bonus is worth claiming or not:
- Wagering Requirement: This refers to the amount of times you need to wager the bonus amount in order to withdraw your winnings.
- Game Contributions: Sometimes not all games contribute equally to the wagering requirement. For example, if table games contribute 10%, you’ll need ot multiply the wagering requirement by 10 if you’re playing table games.
- Game Exclusions: For some bonuses you can’t play certain games at all. This could simply not contribute to wagering or it could void your bonus entirely.
- Qualifying Deposit: If you’re claiming any kind of bonus that needs a deposit to unlock it, then the qualifying deposit is the smallest amount you can deposit to get that casino bonus.
- Payment Exclusions: Some bonuses can only be claimed using certain payment methods. Skrill and Neteller are commonly excluded, so check the terms carefully.
- Expiry Date: All bonuses come with a date that you need to use them by, this includes completing the wagering requirement.
- Win Cap: Most bonuses have a max win or win cap. This refers to the largest possible amount that you can win using that bonus.

UK Casino Bonuses – FAQs
-
Can I claim more than one welcome bonus?
No, most online casinos only allow one welcome bonus per new customer. However, some casinos offer multi-part welcome packages that include rewards spread across several deposits. -
Do online casino bonuses work on all games?
No, not all bonuses can be used on every game. Lots of bonuses, especially free spins, are only usable on specified games – so make sure you check what they are. What’s more, although slots will usually contribute 100% toward your wagering requirements, table games like blackjack or roulette often contribute a lot less or sometimes not at all – so make sure you check all the details first. -
What are wagering requirements, and how do they work?
Wagering requirements refer to the number of times you need to wager your bonus (or bonus plus deposit) before you can withdraw your winnings. For example, a 35x wagering requirement on a £10 bonus means you must wager £350 before cashing out. -
Do welcome bonuses expire?
Yes, most casino welcome bonuses have an expiry date. Some bonuses expire within 7 days, while others may last 30 days or longer. Be sure to check the terms to avoid losing your bonus. -
Can I claim a welcome bonus on my mobile device?
Yes, most online casinos allow you to claim welcome bonuses via their mobile website or casino app. The process is generally the same as on desktop. -
What is the minimum deposit to claim a welcome bonus?
Most welcome bonuses require a minimum deposit, often between £10 and £20. Always check the T&Cs to see the exact amount needed to activate the bonus. -
Can I withdraw my casino bonus funds immediately?
