    Casino deposit bonus – What is that?

    How a casino bonus in the UK works

    A casino deposit bonus is a bonus that a player gets when they make a deposit at a casino. It is often given immediately after you make a deposit, with X amount of bonus money being added to your account to play with on top of your own money. This increases your bankroll and allows you to place more bets which gives you more chances to win.

    However, this bonus money isn’t yet actual money so it cannot be withdrawn until certain requirements are met. Otherwise, casinos would not be making any money. So just going straight for the biggest casino bonus isn’t always the best idea. You’ve got to consider the terms of a first deposit bonus to understand what’s happening. All casino bonus offers have terms attached so you need to know what they look like.

    Example. The casino offers a 100% casino bonus up to £50 with a wagering requirement of 25 times the bonus money when you make a deposit. You want to claim the maximum bonus so you decide to deposit £50 which the casino then matches. You now have £100 in your account (£50 of money you deposited plus £50 bonus money offered by the casino). Before you are eligible to make a withdrawal you need to bet at least £1250 on slots before your withdrawal request can be accepted (25 x £50).

    Take notice! There are usually other terms and conditions that apply too. These can be for example:

    • Activation: It’s possible that you’ll need to activate the bonus to use it
    • First deposit bonus code: Although rare, look out for any first deposit bonus codes that sites display. You’ll need to enter this when depositing to get the offer.
    • Eligible payment method: There are many casino payment methods, but some are not eligible to trigger casino bonuses. Make sure to check what’s eligible.
    • Time limit: You need to wager the bonus money in a certain time period (eg. 7 days)
    • Eligible games: Slots usually wager 100% (except certain jackpot slots and other special slots) but table games and live games usually don’t wager that much. Sometimes not at all.
    • Max bets: You are often only allowed to bet a maximum of £5 per spin when completing the wagering.

    Because it is common that there are other requirements besides the wagering requirements, we always recommend reading the terms and conditions first. If something looks too good on the first sight, it usually is.

    You will almost certainly be given a casino deposit bonus when signing up at new online casinos. This is because all casinos want you to play at their site and there’s no better way to tempt us in than offering extra funds through a first deposit bonus to play with. The best casino deposit bonus sites have more of these offers for existing players to keep them happy as well. However, just remember that the terms aren’t always the same, even if it’s the same casino offering the bonus. So always check them first.

    How to make money from online casino bonuses

    You can only win real money from online casino bonuses when you complete any wagering requirements that are attached. That might not sound too daunting at first – but just check the example above again. A £100 bonus with x25 wagering, you would need to bet a total of £2500 before it was turned into real money. That’s a lot. And x25 wagering? Very few casino bonus sites go that low. Wagering is usually between the x30-x40 mark so the total will be even higher.

    So can you actually win money from a casino bonus or not?

    Yes, you can. Wagering requirements will make it very difficult to do – and you are basically relying on luck. But it can be done – and we’ve got proof. We played at Duelz Casino and took their bonus. This is a screenshot showing our wagering being 98% completed:

    We managed to complete it in full soon after.

    This left £153.78 of real money in our account as you can see:

    We were able to withdraw it to our account, proving that beating wagering requirements is possible – despite being unlikely. You can read more about this experience within our Duelz Casino review.

    Best casino bonus – How to choose?

    Guide to different casino bonus factors

    There are several things that you need to take into consideration before choosing the best casino bonus. As we’ve said, bigger doesn’t always mean better. Here’s a casino bonus guide that we recommend evaluating before making that first deposit:

    Amount to deposit

    How much are you planning to deposit? Usually, the first deposit bonus is the best bonus that casinos offer so you might want to get the maximum benefit from it. If you are for example planning to deposit £50, choose a casino that offers a bonus up to £50 in order to get the maximum bonus.

    However, if you just want to try a casino bonus site out for the first time then you might want to keep the deposit low. That way you can test it out to see if you like it. But make sure to check the minimum deposit amount first. If your payment is lower than that then the offer won’t be triggered. Here are two of the most common amounts:

    Deposit Bonus Casino

    Does the casino with the deposit bonus have a valid license and a good reputation? There are many to choose from so select a good one. Also, make sure that:

    • Games the casino offers are good
    • Your language is supported
    • Payment methods are suitable
    • The platform works well on your device

    Wagering requirements

    Keep an eye on this and especially look whether it is bonus money or bonus money plus your own money that you have to wager. A high bonus isn’t great if the wagering requirement is unreasonable. Also, make sure that you can wager money on the games you are about to play. Sometimes slots from a certain provider aren’t allowed in the wagering, for example. There are a few casinos that offer a no wager bonus.

    We often include wagering requirements within the quick terms and conditions popup in our casino bonuses list.

    Just make sure to double-check the wagering once you choose your casino sites. We aim to keep all the information up to date but casinos are known to change terms at short notice. Please let us know if you spot anything incorrect.

    To figure out exactly what you’ll need to wager, you can use this casino bonus calculator:

    Other terms

    These vary from casino to casino and there might be something in the small print that makes the bonus practically useless. Things like a too-tight time limit to wager or a maximum amount that you can win.

    50% casino deposit bonus (wagering 20 times)

    This is perhaps the smallest bonus you’ll see but casinos generally offer more. You’ll see this marked something like 50% up to £50. However, this is the structure for all casino deposit bonuses no matter the size. Let us explain.

    The percentage (50% in this case) explains how much the casino is willing to match whatever you deposit. However, they include a maximum cap of “up to £50” in this case. This prevents players from depositing massive amounts in exchange for a huge amount of bonus money.

    Let’s use 50% up to £50 as an example and apply some deposits to it:

    • Deposit £100 = £50 bonus money
    • Deposit £50 = £25 bonus money
    • Deposit £150 = £50 bonus money (because this offer has an “up to £50” maximum on bonus money).

    Also, you often need to complete wagering requirements before you can withdraw any bonus money. Let’s say that you got the full £50 bonus money with 20 times wagering. You would then need to use the £50 bonus money to bet £1000 (20 x £50) on eligible slots or casino games before you would be eligible for a withdrawal. Pay special attention to the terms and conditions here as some casinos require you to wager the bonus + deposit amount. If that was the case and you deposited £100 then it would change to £3000 instead (20 x £150).

    100% casino deposit bonus (wagering 20 times)

    This is the most typical casino bonus on offer and is commonly referred to as a match bonus. You’ll see this marked like 100% up to £100 which would mean that a casino will outright match whatever you deposit up to a maximum of £100.

    Let’s take this example and assume you deposit £100. The casino will then match your deposit with £100 bonus money. Any higher deposits will be capped at this amount. When using your £100 bonus money, the wagering is set at 20 times which means you would have to play £2000 (20 x £100) on slots before you would be eligible for a withdrawal.

    200% casino deposit bonus (wagering 20 times)

    Not as common but there are still a few casinos that offer this bonus. You’ll see a 200 casino bonus marked like 200% up to £200 which would mean that a casino pays twice the amount you deposit in bonus money up to a maximum of £200. Usually, casinos that offer this bonus have a bonus for the second deposit too.

    Let’s assume you deposit the same £100 for this example. You will then get £200 from the casino as bonus money. Any higher deposits will be capped at this amount. With the wagering being 20 times you would have to use the £200 bonus money to play £4000 (20 x £200) on slots before you would be eligible for a withdrawal.

    300% casino deposit bonus (wagering 20 times)

    Quite rare and at the moment there aren’t really any casinos that offer this type of bonus. However, when they do you’ll see this marked like 300% up to £300 which would see you get three times the amount that you deposit up to a maximum of £300.

    You deposit the same £100. You would then get £300 from the casino. Any higher deposits will be capped at this amount. With the wagering being 20 times for the bonus money you would have to use it to play £6000 (20 x £300) on slots before you would be eligible for a withdrawal.

    400% casino deposit bonus (wagering 20 times)

    This is more commonly seen than the previous 300% bonus for some reason. It’s marked like 400% up to £400 which would mean the casino pays four times the amount that you deposit up to £400. Remember though that this would be a lot of bonus money which mean quite a lot of wagering to do. Also, keep an eye on the other terms. Benefitting from a bonus this big isn’t usually easy to do. Read the small print.

    Let’s assume you deposit £100 again. You would then get £400 from the casino. Any higher deposits will be capped at this amount. With the wagering being 20 times for the bonus money you would have to use it to play £8000 (20 x £400) on slots before you would be eligible for a withdrawal.

    500% casino deposit bonus (wagering 20 times)

    These offers are extremely rare but it’s still worth knowing how they work just in case. It’s marked like 500% up to £500 which would mean the casino pays five times the amount that you deposit up to £500.

    Let’s assume you deposit £100 for this example. You would then get £500 from the casino. Any higher deposits will be capped at this amount. With the wagering being 20 times for the bonus money you would have to use it to play £10,000 (20 x £500) on slots before you would be eligible for a withdrawal.

    In all honesty, this kind of bonus would be best for trying something out rather than converting into real money. That’s because 20 times wagering is considered low and many casinos often double this to 40 times or even higher. It would virtually be impossible for you to wager it in full so you need to consider whether to use it.

    Casino Bonus – How to calculate

    Once the percentages start to rise it can be tricky to keep up. However, if you want to know how much to deposit in order to get the maximum bonus then there’s a simple formula. You take the maximum bonus that’s possible and divide it by the percentage which is split into decimal places after the first number. It’s best explained in an example

    100% up to £100 – How to max the bonus

    • Maximum casino bonus available = £100
    • The first digit of the percentage is 1 (no decimal places are necessary as the other numbers are 0)
    • Divide £100 by 1 for your answer (£100 / 1 = £100)
    • So £100 is what you need to deposit to get the full bonus in this case

    Let’s now try a 200 casino bonus example that’s a little trickier.

    125% up to £200 – How to max the bonus

    • Maximum casino bonus = £200
    • In this case, you would split the percentage to reach two decimal points – 125% =1.25
    • £200 / 1.25 = £160
    • £160 is what you need to deposit to get the full £200 casino bonus

    NOTE: For percentages lower than 100, you place the numbers after the decimal points – e.g. 50% would be 0.5.

    The best thing is you can use this formula every time to quickly find out how to get the biggest casino bonus from each offer. Just load up your device’s calculator and try it out.

    Is casino bonus worth using?

    It depends. If you are just planning on playing a quick session it might not be necessary since the wagering always takes a while. However, you always get more playing time when you have bonus money in play. The more money you have to play with the better chance you have of winning as well, so a casino bonus can help there too. And if there isn’t any urgent time limit on the wagering, you can always return and continue your session.

    When playing at a casino that is licensed by the UK Gambling Commission, the following rules are in place:

    One problem is that some terms and conditions are difficult to understand. The UK Gambling Commission issued a warning about this in February 2022 which shows that this is still a problem. If you ever don’t understand something, it’s best to either not take the bonus or ask customer support to explain everything to you. This is to save you from problems further down the line.

    Exclusive casino bonus

    One of the ways we help to make an offer more enticing is by getting an exclusive casino bonus. This is an upgrade to the usual deal that a casino offers, with either extra bonus money or something else added in.

    We make sure to highlight all our exclusive casino bonuses in several places. Such as above, where we will make a casino with “Exclusive”, “EXCL” or similar. Out of all the options, probably our most popular exclusive casino bonus is from MrQ. To get it, you can either visit their link above or from the MrQ Casino review.

    Casino deposit bonus – Should I reject?

    Nowadays most casinos give the deposit bonus automatically after the deposit. In order to decline the casino deposit bonus, you need to contact support before starting to play so that they can inform you how to reject it. If you start playing you cannot reject the bonus anymore unless it is forfeitable.

    For casinos that use bonus codes, rejecting the first deposit bonus is generally easier. Just don’t input the bonus code and the deposit bonus won’t be credited after your deposit. However, most casinos don’t use bonus codes anymore.

    But why would you actually choose not to take a first deposit bonus?

    Winnings Cap

    Some first deposit bonus casinos will include a clause which limits how much you can actually win from the bonus. For example, you may well see something like “Max withdrawal amount of £100” within the terms and conditions.

    This means that you can only ever win up to £100 in real money. Any wins that went over this amount would be taken away from you.

    Limited Game Selection

    You may also find that your deposit casino bonus can only be used on a few games. That’s because some sites restrict what the offer is available for.

    If it’s a small boost then you might not mind. However, anything from a 100 casino bonus, 200 casino bonus, or higher would mean playing the same slot(s) over a longer period.

    Bet Limits

    One thing that pretty much every casino deposit bonus has is a maximum bet limit. In most cases it’s £5 – and this means that you can only bet up to £5 per spin on a slot when completing the wagering requirements.

    If you happen to accidentally bet more than £5 – even if it’s only on one spin – then the casino will have grounds to remove your bonus and any winnings you made from it.

    Too High Wagering

    With £5 betting limits, it’s no secret that wagering a first deposit casino bonus can take a while. Therefore, if the wagering requirement is too high then it might not be worth taking up (between x30 – x40 wagering is the usual benchmark).

    Anything higher than these amounts would mean you need to spin for longer. Of course, the more wagering you have to do the more likely you’ll lose your casino bonus winnings in the long run.

    If you’re not happy with these kinds of terms then we recommend selecting a different first deposit bonus until you find one that’s appropriate.

    Casino bonus UK

    If you currently reside in Great Britain and you’re looking for the best casino bonuses for UK players, pretty much every casino listed here has offers in British pound. However, all sites on our UK online casinos list must adhere to the rules of their licencing body – the Gambling Commission. Over the years, the Gambling Commission has implemented a few changes which have affected casino bonuses in the UK.

    On 7th May 2019, the Gambling Commission introduced rules which meant that players signing up at a new gambling site must have their name, address, and date of birth verified before they can play. This means that a UK player can’t deposit and subsequently get a casino bonus until this ID verification has taken place. In most cases, it happens automatically. Yet, it’s common for sites to ask players for verification documents too. You can view more about online casino verification UK for a complete overview.

    The Gambling Commission also banned the use of credit cards to make deposits at gambling sites on 14th April 2020.

    Best first deposit bonus casino UK

    The most common type of casino bonus is a first deposit bonus which all the casinos above offer. This means you will receive a bonus after making your very first deposit which gives you more money to play with before you’ve even placed your first bet. However, not all first deposit bonuses are the same – with some sites being much better than others.

    If you’re looking for a popular deposit bonus casino, UK and other players around the world can check out these options:

    The best first deposit bonus casino is a casino that is transparent in its terms and conditions. Some may also have additional offers afterwards too for the complete casino welcome bonus package.

    Good casinos also allow you to forfeit your bonus after you have already started playing. This is called a forfeitable bonus.

    First deposit bonus – Is it forfeitable?

    • You first start playing with your own money
    • If you lose it then you play next with the bonus money – giving you another chance to win.
    • However, if you win using the real money first then you can withdraw your winnings straight away
    • You just need to give up the bonus to do so (but you’ve already won so you don’t need this!)

    Of course, if you have started playing with the bonus money already then this cannot be done anymore. You used to only see forfeitable bonuses at really good sites. However, they are much more common now after the UK’s Competitions and Markets Authority (CMA) put pressure on the industry to change (BBC – Betting firms to stop ‘unfair’ promotions). They specifically stated that “players will not be required to play multiple times before they can withdraw their own money” which made it a lot easier to withdraw than before.

    Casino first deposit bonuses – Cashable?

    Another thing that’s great to see is a cashable casino bonus. This is where you get to keep your bonus alongside any winnings when you go to cash out.

    Let’s give you an example – you get a £100 bonus, win £100 with it, complete the wagering, and then go to make a withdrawal:

    • Cashable casino bonus – Let’s you withdraw the full £200, meaning you keep the £100 bonus money as part of your winnings.
    • Non-cashable casino bonus – Let’s you withdraw only £100, removing the initial £100 bonus money that you were given.

    Of course, it’s always best to play at a casino with a cashable bonus. However, they don’t always make this clear in the terms and conditions. Instead, we often resort to asking the customer support to see what the deal is. This might sound a bit of work to begin with but if you win then it could mean a nice little extra on top.

    Alongside manually looking through the available options, you can also search and filter. The search bar at the top of the page allows you to search for a specific casino. If we have it, you will be able to see a review that will contain their first deposit bonus.

    We also have a Categories filter. This allows you to view the first deposit bonuses of specific types of casinos. For example:

    • Live Casinos – View the first deposit bonuses of casinos that we consider to offer the best live experience

    Online casino bonuses for existing players

    Once you’ve settled in at a new site and your casino welcome bonus has been used up, you’ll want to learn of online casino bonuses for existing players. Make no mistake, loyal players should be given extra treats to reward them for continuing to play. Otherwise, players can, rightfully, forget them and move on to a different site where they are appreciated better.

    There are many ways that an existing player can get an extra casino bonus quite regularly. The most obvious place is the “Promotions” tab which most sites have under the menu. Here you will find all the casino bonuses that are currently available.

    One of the most popular types of recurring offers is the game of the month bonus. This is when the casino gives you a bonus to be used on a specific slot or set of slots. It’s commonly given for new slots that have just been released so you can try it out.

    Many casinos also run loyalty schemes and programs for a more personal touch. Some casinos go beyond just casino bonuses as well by offering faster payouts, dedicated managers and more perks. However, one of the best ways that casinos like to reward their existing players is when they turn a year older.

    Birthday bonus casino

    There’s nothing more personal than a reward from a birthday bonus casino. You can log in on the big day and be treated to something special. Of course, a casino won’t publicise your birthday bonus to everyone – so make sure to keep your eyes peeled on your email or ask customer support if they would kindly be able to offer you something.

    Also, when it’s the casino’s own birthday, prepare to be showered with bonuses. Sites often like to make a big deal of their own special day with numerous promotions and tournaments for the occasion.

    FAQ – Your casino bonus questions answered

    A casino bonus is often useful as it gives you extra bonus money to play with. However, the bonus money can either be given as soon as you deposit or as a backup if you lose.

    If you want to try out slots and games without using your own money then getting the bonus money straight away can be useful. However, if your goal is purely to win, you may want the extra bonus money as a backup just in case you lose.

    Casino bonuses are available for new players at pretty much all sites. You just need to create and verify an account and then make a big enough deposit. Your casino bonus will then be ready for you to use.

    Yes, you can. However, you usually can’t withdraw what you win when using a casino bonus without completing the wagering requirements first.

    For example, if you won £100 and the wagering requirements were x20, you would need to bet £2000 using your winnings before you could withdraw it. You can find more examples within our page.

    That depends. If you just want as much bonus money as possible to try out new or different games then this could be a good move. However, just remember that you most likely won’t be able to withdraw what you win without completing wagering first – and large casino bonuses often make wagering even higher.

    You can avoid wagering requirements by not accepting a bonus and just playing with your own money. You can also avoid them by selecting a bonus with no wagering which pays out real money rather than bonus money. This is a popular choice, so all casinos with these bonuses are clearly highlighted.
