Introduction to Casino Bonuses
Spinning your deposit and getting a huge win is, of course, a dream come true. But what if not only the winnings, but also the money you wagered, were from the casino? Enter the casino bonus!
Gambling online can be enjoyable, entertaining and rewarding. And with a bonus, it is all the more fun! A casino bonus is exactly what the name suggests: a bonus given by a casino to you, the player.
A “bonus” can be spins, bonus money, chips, cashback, or really any gift the casino wants to reward you with. The most common casino bonuses are free spins and match bonuses (which we’ll get back to). In short, this means spins or additional money given to a player for free by the casino.
Casino bonuses can be given at any time. The first bonus you meet is usually in the form of a welcome bonus. From there, a casino with bonuses will reward both new customers and seasoned players through different campaigns, tournaments and reload bonuses. It’s just important to find and sign up at a casino that offers bonuses in plenty, with good terms attached.
Why do Online Casinos Offer Casino Bonuses?
It might sound silly for online businesses to give out free money and winnings without asking for much, if anything, in return, but it is all part of their marketing. The casino industry is a competitive one, and players are sought after. Therefore, benefits like a great bonus can be their make or break.
Casino bonuses are simply a win-win for the casino and players alike. The player will get a great start to their experience at the casino, while the casino will get a happy new player. Especially for new casinos, it is important to offer a great bonus that attracts players to sign up.
Casino Bonuses for New Players
Let’s take a closer look at different types of casino bonus offers you might come across:
1. Deposit Match Bonus
This is simply a bonus that matches your deposit with a certain amount. The amount matched is dependent on two factors: the match percentage and the deposit range covered.
The match percentage
The most common deposit match bonus is a 100% match bonus. This means that the casino will give you exactly the same amount of money as you deposited. If you deposit £50, you’ll get £50 from the casino and have a total of £100 to play for. But you might meet other match percentages too.
Some casinos are more modest than others and only offer, for example, a 50% bonus. This means that you won’t be able to double your money, but they’ll give you an extra £25 on top of your £50 deposit. 50% might not sound like a lot, but remember that it is still “free money” to play for!
If you think the smaller match percentages sound boring, you might be more interested in casinos that have more of a “go hard or go home” attitude. These casinos can give match bonuses of 200%, 300% or even 500%! This means that a £50 deposit can result in a total of £300 to play for – thanks to a £250 bonus.
A casino’s match percentage of a bonus should always be clearly stated in its description and terms. But if a casino mostly advertises a “deposit match bonus” without specifying the percentage right away, you can be pretty sure it is a 100% match.
The deposit range covered
Before you start dreaming about the thousands of pounds you will get for free from a casino, we have to mention the second factor of a match bonus: the deposit range covered. By that, we refer to the minimum deposit and maximum deposit amount covered by the bonus.
Most casino bonuses will require a minimum deposit of £10 or £20. This means that if you deposit less than this amount, you won’t be eligible for the bonus. And the same applies to a maximum amount.
Most bonuses have a cap on how much you can claim from the casino. However, where the minimum deposit amount is normally quite stable at £10 or £20, no matter which casino you visit, the maximum cap varies a lot. Some casinos only offer bonuses up to £25 or £50, while others match deposits of £100 or more.
2. Free Spins
Free spins are as simple as they sound: spins that are free. These spins give players the chance to spin slot games without spending any of their own money. But unlike when playing free demo versions of casino games, players actually have the chance to win real money with free spins. It is simply the casino that pays for them. So if your free spins result in any winnings, those winnings are yours to keep (as long as the terms are kept).
These types of bonus spins can normally be used at specific slots selected by the casino. Common free spins slots include the popular favourites Starburst or Book of Dead.

3. No Deposit Bonus
Most welcome bonuses are linked to a player’s first deposit(s) at the casino. But sometimes, a casino will grant a bonus for simply signing up. This bonus will simply reward players for registering an account. This is called a no-deposit bonus and will normally be a couple of free spins or a few pounds worth of bonus money. You can enjoy this bonus without having to add any payment details to your account.
The possibility of getting a casino sign-up bonus is getting more common these days. Some casinos also offer no-deposit bonuses to active players from time to time. The bonus might get added to your account automatically or require you to claim it.

4. Welcome Bonus
A welcome bonus is a bonus a casino will grant new players who register an account on their site. This is often the main bonus that casinos advertise on their website. With a casino welcome bonus, UK players can get started with some extra funds in their bankroll. Often, a welcome package combining both free spins and a deposit match bonus is offered.
A welcome bonus can come in many shapes and sizes. Some casinos offer registration bonuses without any deposit required. Other casinos require the player to make a first deposit before getting the bonus. And sometimes the welcome package is given on more than just one deposit!
Best Casino Welcome Bonus UK
While any casino bonus is a nice treat, the biggest bonuses are normally welcome bonuses for new players. So before joining a casino, it’s important to check for a good welcome bonus. In this guide, you can find UK-licensed casinos offering the very best bonuses for British players at the moment.
Welcome bonuses come in all shapes and sizes, with a combination of a deposit match bonus and free spins being the most common. Some casinos will give you the full bonus as soon as you sign up, while others will spread the welcome bonus out across several deposits. The latter is often referred to as a welcome package, rather than a standalone welcome bonus.
Before signing up, it’s important to make sure you understand what type of bonus you’ll receive and on what terms. Here at Kabono, our reviews always outline if the welcome bonus is given in full on the first deposit or if it’s across several deposits. That way, you can find the best welcome bonus for you!
Casino Bonuses for Existing Players
Since most casinos focus on their welcome bonus in order to get new sign-ups, it often seems that online casino bonuses are meant mainly for new players. But that is not the case at all! Even if they don’t heavily advertise it, almost all casino sites will offer bonuses to “old” and loyal players, too.
These are the different types of bonuses offered to existing customers:
1. Loyalty & VIP Programmes
Any serious casino will offer some sort of loyalty or VIP programme for loyal players. The programmes often have different levels, where the more you play and win, the higher your level will be!
While climbing up the level ladder, you get to enjoy various bonuses and perks that are exclusive to VIP players. Some loyalty programmes are available to all players while others are exclusive, invite-only programmes for the most active players.
2. Reload Bonus
If you haven’t been active on your casino account for a while, a lot of casinos will reach out to you and offer a reload bonus. This is most often a match deposit bonus that will match your next deposit up to a certain amount. This is a win-win situation, just like a welcome bonus. You will get a new bonus to get you back into the game, and the casino will get its player back.
3. Cashback
Some casinos also offer cashback on losses. This might be given through a campaign, but some casinos offer cashback on all deposits. Normally, a cashback bonus will give you 10% of net losses. This means that if you wager and lose £100, the casino will fund your account with £10 back. Often, cashback bonuses come without any wagering requirements.
An example of this is the No Bonus Casino. They don’t offer any traditional bonuses, but instead, all players always get 10% cashback on their losses.
4. Free Spins from Promotions
Free spins aren’t reserved exclusively for no-deposit bonuses and casino welcome packages. Often, you’ll find casino bonus offers containing free spins, which the casino will give to all of its players in their campaigns. The campaigns can be seasonal, for a specific holiday or anniversary, to celebrate your birthday, or to boost the release of a new slot.
5. Tournaments
In addition to the traditional bonuses already discussed, some casinos will have their own tournaments, gamification quests, or branded and trademarked bonus schemes. Tournaments are fun and easy to join, and normally come with a large prize pool. Often, you won’t even need to opt in or do anything other than normal – simply see the tournament details to see which games are eligible and join.
6. Network Promotions
Many casino sites are part of different networks or operated by the same company, and will often offer the same type of promotions. These can be “network promotions” available at many different casinos. Such offers can be weekly, monthly or random promotions. Normally, they can be found and joined from the promotions page of a casino.
Casino Bonus Codes
In order to get the best casino bonuses, you sometimes need to make use of exclusive casino bonus codes. They can be found on the casino’s website, given through email campaigns, or created specifically for comparison sites such as Kabono.
Some of the casino bonuses we recommend come with bonus codes, which might be a bit confusing if you are new to the gambling world.

How to Find Online Casino Bonuses
Since most online casinos focus mainly on their big welcome bonus, it can feel a bit difficult to find which other bonuses are on offer. Before signing up, it is important to know that the casino will also offer promotions in the long run.
To make it easy, most online casino sites will have a Promotions or Campaigns page, which can be found on their menu. Here they will list all ongoing promotions, including the welcome bonus and bonuses for players who are no longer new.
Many UK casinos will also send out promotional messages through email and SMS. While these might feel a bit annoying, we also recommend you opt in and check out these notifications. That is simply because if you ignore them, you might miss out on exclusive and lucrative campaigns!

Casino Bonus Terminology
When reading about casino bonuses, you often come across terms such as “wagering requirement“, “no wager free spins“ and “online casino no deposit bonus”. But what does it all mean? Here we’ll go through and explain both common and more unknown gambling terms related to casino bonuses.
By learning this casino bonus terminology, you will never make the mistake of accepting an unfavourable bonus in the future. So keep reading as we list bonus terminology from A to Z and become a pro!
B
- Bonus spins: A bonus that offers spins on a slot machine (or another spinning game). They allow you to play the game for free for a certain number of rounds while being able to score real wins (same as: free spins).
- Bonus code: A code needed in order to claim a specific bonus. Similar to a coupon code, the code will consist of letters and/or numbers, descriptive or random. Players normally include the code 1) in the cashier when making a deposit or 2) by contacting customer support.
- Bonus policy: A casino’s terms and conditions related to bonuses. Often, each promotion will have its own conditions listed, and then a bonus policy is linked with the overall terms of the casino’s bonuses.
- Birthday bonus: A bonus given as a birthday gift. This can be a bonus you get on your birthday (from the date of birth registered in your account) or to celebrate a birthday/anniversary of the casino.
- Bingo bonus: A bonus given for bingo games specifically. For example, it can be cash that can only be spent on bingo games or a certain number of free rounds of bingo.
C
- Cashback: A type of bonus where the casino gives back part of lost wagers. For example, it can be a 10% cashback up to £100. This means that 10% of your deposit (up to a maximum of £1,000) is paid back if it is lost.
D
- Deposit bonus: A bonus that is given together with the act of making a deposit. The most typical one is a match bonus. This is when the casino adds additional money to your account in addition to the deposit amount you made. But many other bonuses are also technically deposit bonuses, such as many free spins offers, as they require a deposit to get them.
E
- Excluded payment methods: Sometimes, the terms and conditions of a bonus will state that deposits made using certain payment methods are not eligible for the bonus. This means that these payment methods are excluded from the bonus offer. Often this includes e-wallets such as Skrill and Neteller.
- Exclusive bonus: A bonus that is somehow exclusive, for example, only available to selected players or on a game that is exclusive to the casino.
- Expiration time: Bonuses don’t last forever. Every bonus will come with an expiration time for how long it will be available. This might, for example, be 24 hours or a week. After this time, the bonus will be lost if it has not been used and played through yet.
F
- Free bet: A typical sports bonus offering players free bets to use in the sportsbook. It might, for example, be a set of free bets worth £10 each, which have to be played as one round (not split up into 10 bets worth £1).
- Free spins: A bonus that awards spins that can be used to play a slot game for free, with the chance of winning real money (same as bonus spins).
L
- Leaderboard: Often, casinos host tournaments where players are placed on a leaderboard according to their score/result. A prize pool is then normally divided among the top X players on the board.
- Live casino bonus: A bonus that can be used on live casino games exclusively. It can be given as chips to use in specific games or a simple deposit bonus where the bonus money is only eligible to use on live dealer titles.
- Loyalty program: A type of scheme many casinos offer where players are rewarded for their loyalty. Normally, the program consists of several levels that players can climb up from being active at the casino. Most loyalty programs are available to all players, while VIP programs are invite-only for the most active players.
M
- Match bonus: A bonus where the casino matches a player’s deposit amount with a certain percentage, up to a certain amount. A casino might, for example, offer a 100% match up to £100, meaning that if a player deposits £100, the casino will add £100 in bonus funds, and the bankroll will consist of £200 in total. But it can also be 50% or less, or 200% or more, all depending on the casino.
- Maximum bet: The maximum amount allowed to bet per round while playing with a bonus. This is so that a bonus can not be used to place just one large bet at a high roller table, but instead has to be divided into several smaller bets.
- Maximum win: The maximum amount players can win when playing a bonus. Some casinos restrict players from winning the biggest prizes or jackpots from bonus funds.
- Minimum deposit: The minimum amount a player has to deposit in order to receive a bonus. Some bonuses don’t require a deposit, while others require a minimum of £10 or more in order to “buy” the bonus.
- Minimum bet: For some bonuses, there might also be a minimum bet rule in place. This is normally the case for sports bonuses where players have to place a bet of a minimum of X in order to get or be able to use a free bet.
N
- Network tournament: Often, the tournaments and promotions offered at a casino are not just offered for the players at that casino, but also at other casinos running on the same network. This means that a prize pool will be split among a large pool of players.
- No deposit bonus: A bonus that does not require a minimum deposit in order to get it. Often, the bonus is given directly upon signup or otherwise automatically. However, sometimes you might have to contact customer support to get it (since it won’t be triggered by a deposit). Read about no-deposit bonuses.
P
- Prize pool: Many casino tournaments and other promotions come with a large prize pool that will be shared among several winners. This can be a local prize pool for the casino in question only, or a shared one for several casinos in the same network.
- Promotions: Various competitions and weekly bonuses that are offered at a casino. Normally, an online casino will have a promotions page where all active bonuses are listed.
- Profit boost: A bonus normally offered for sports betting, where players can get extra profits from a win.
R
- Referral bonus: Some casinos offer you a bonus if you refer other players to sign up (and make a deposit at) the same casino. This is known as a referral or refer-a-friend bonus.
- Registration bonus: A bonus that is given straight upon registration, normally before you even make a deposit.
- Reload bonus: A type of bonus normally given to players who have not been active for a while. In order to “reload” the player, additional money is added to their deposit, for example, as a 50% match.
S
- Sticky bonus: A bonus that can be used to play, but never withdrawn.
T
- Tournament: A type of casino promotion where players compete against each other to win top prizes. Tournaments normally require you to do specific actions in a game or get the best score from your bet (for example highest win).
V
- Validity period: How long a bonus is valid and available for (same as expiration time).
- VIP bonus: A bonus offered to VIP players exclusively.
- VIP program: A special loyalty scheme that is normally offered as an invite-only. The most active players at a casino can be invited to join the program and receive exclusive perks.
W
- Wagering requirement: Bonus terminology that is often found in the terms and conditions of a bonus. This refers to the number of times a bonus has to be wagered (played through) before any potential winnings can be withdrawn.
- Wager-free: A bonus that does not have any wagering requirements is often advertised as wager-free. A casino offering this is often referred to as a no-wagering casino.
- Welcome bonus: A bonus that is given to new players to “welcome” them to the casino. Normally, this is the biggest bonus a casino offers in order to get new users to sign up. The casino is often given in correlation with the first deposit made, but can also be a no-deposit bonus.
- Welcome package: Some casinos do not just offer one bonus, but several bonuses to new players. This is often referred to as a welcome package. A casino might, for example, give bonuses on a player’s first four deposits, not just the very first one.
Basic Casino Bonus Terminology You Have to Know
The terms listed and explained above are a selection of the most widely used casino bonus terminology. But of course, some of the terms are more commonly used than others. So if you are just getting started, these are the absolute must-knows:
- Welcome bonus: A type of bonus given to new players in order to welcome them to the casino. The bonus can consist of extra money, free spins or something else, depending on the casino. This is generally the biggest bonus offered at any casino.
- Free spins: A typical type of casino bonus that offers players the chance to play a slot game for free. By getting a certain number of game rounds (spins), players can spin the wheels for free while still having the chance to win real money.
- Wagering requirement: One of the most typical terms and conditions of casino bonuses. This states how many times a bonus has to be wagered before any winnings can be withdrawn as real money.
