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 that are just starting out, it is important to offer a great bonus that attracts players to sign up.

Different Casino Bonuses

Let’s take a closer look at different types of casino bonus offers you might come across while playing at an online casino

Match Bonus

A match bonus, also called a deposit bonus, is a bonus that will simply match a percentage of the deposit you make – up to a set amount. An example can be a match deposit of 100% up to £200. This simply means that, if you deposit £200 from your payment method, the casino will give you £200 as a bonus. This will in total give £400 for you to play with at the casino.

A deposit match bonus can also give a 50% bonus or more than a 200% bonus, depending on the casino. If you deposit the maximum amount, you can gain a lot of extra playing money with these bonuses.

For many welcome bonuses, casinos will give a deposit match bonus on the first few deposits. Sometimes this is not only for the first deposit but also the second, third, fourth and maybe even fifth. Just make sure to deposit the minimum amount required to get the bonus(es).

Free Spins

Free spins are as simple a thing as it sounds: 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 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. Learn more about and see all the best free spins bonuses in our dedicated guide.


  • Choose from three welcome bonuses
  • Lots of promotions with daily casino deals
  • Large game selection with exclusive games
  • Live chat not available 24/7

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. A no deposit casino bonus is normally a couple of free spins or a few pounds worth of bonus money. This you can enjoy without having to even 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 a small action to claim it (such as contacting customer support).

Learn more about and see all no deposit bonuses in our dedicated guide.

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 casinos advertise on the casino 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!

To find out the specific details of a welcome package, it is important to read the terms and conditions. This goes for any bonus: players need to ensure that all details are clearly understood before accepting the bonus. Sometimes a bonus code might be required, there can be a 40x wagering requirement or the bonus might only be valid for 7 days etc. That is why it is always important to check when it says T&Cs apply.


It is always important to read and understand the terms and conditions linked to a bonus.

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 Active 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.

Loyalty Programs

Any serious casino will offer some sort of loyalty or VIP program for loyal players. The programs often have different levels which you can unlock where the more you play and win, the higher your level will be!

While climbing up the level ladder, you will get to enjoy various bonuses and perks that are exclusive to the VIP players. Some loyalty programs are available to all players while others are exclusive, invite-only programs for the most active players only.

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 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.


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.

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 their players in their campaigns. The campaigns can, for example, be seasonal, for a specific holiday or anniversary, to celebrate your birthday, or to boost the release of a new slot.


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.

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.

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 at an online casino it is important to know that the casino will also offer promotions in the long run, so it is worth investigating.

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 that 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!

You can also check our casino news articles here at Kabono. We write weekly articles where we list the best promotions of the week and other offers.

Online Casino Bonus Terms

No matter which casino you sign up at or which bonus you opt for, there will always be some sort of terms and conditions attached. The exact terms can vary a lot from one casino to the next. It is important that you understand what the most common terms mean to see which bonus offers the best deal.

Common bonus terms and conditions

Here are some of the most common terms and conditions you’ll probably come across when looking at bonuses

  1. Minimum deposit: The minimum amount you have to deposit in order to be eligible for the bonus. Normally this is £10 or £20. If you deposit less than the minimum required, you won’t get the bonus.
  2. Maximum bonus: The maximum amount at which the bonus is capped. For example, a 100% bonus up to £200 is capped at £200. Even if you deposit £500, you will only get £200 added as bonus funds from the casino.
  3. Maximum win: The maximum amount you can win from the bonus funds/spins. Sometimes the casino limits how much you can win from a bonus. This can for example be to ensure that you don’t win a million-pound jackpot from a £1 free spin.
  4. Wagering requirement: The number of times you will have to wager the deposit, bonus funds and/or wins before you can cash out your winnings. The wagering requirement is normally shown as for example x40 (you need to wager it 40 times).
  5. Valid time period: The time frame in which the bonus is valid. Some bonuses are only valid for 24 hours after you have received them. Others can be played for 7 or up to 30 days.
  6. Excluded payment methods: Any payment methods that will not give an eligible deposit for the bonus. Often e-wallets like Skrill and Neteller are excluded.
  7. Bonus code: A promo code that needs to be included when you make your deposit for it to be eligible.

Casino Bonus FAQ

Below we answer some of the most common questions we receive regarding casino promotions, wagering contributions, casino bonuses etc.

  • What is a casino bonus?

    A casino bonus is any form of money, spins, bets, or other types of goodies that online casinos give their players. In most cases, players have to make a deposit in order to get the bonus. This means that bonuses are most often “bought”, but it is also possible to get bonuses for free.

  • What is a no bonus casino?

    Some casinos don’t offer traditional bonuses and therefore operate as “no bonus casinos”. They might still give cashback or other perks, but no traditional signup bonus etc.

  • What is the best casino bonus in the UK?

    The best casino bonus and site on the market will depend on your personal preferences. Check our top list to find your favourite!

  • What is a wagering requirement?

    Almost all casino bonuses will have a wagering requirement. This will tell the number of times you will have to wager the bonus and/or any potential winnings before you can withdraw your winnings. For example, some casinos require that you wager your bonus funds 45x. This means that if you got a £10 bonus, you would need to play for £450 before you can withdraw your money. A bonus with no wager (wager free) or a low requirement is, therefore, the best and will make it easier to hit the wagering target.

  • How can I get a free casino bonus?

    Many UK casinos offer no deposit bonuses where you can get a bonus like free spins or free money just for signing up at their casino. Simply sign up at a casino that offers no deposit bonuses and see how to claim it.

  • Are online casino bonuses safe?

    Yes. All legal online casinos have to be licensed and regulated by the Gambling Commission in order to keep open, and therefore their bonuses will have to be fair and safe. Just make sure that you are signing up at a casino that is licensed by the UKGC. Any bonus offer received through is 100% safe. We only recommend licensed casinos that keep your bonus funds and deposit bonus safe.

  • Are casino bonuses worth it?

    Yes, in most cases it is worth opting in for casino bonuses as they give you more money/spins to play for. Just pay attention to the terms and conditions attached and make sure you only accept bonuses from licensed casinos.

  • Why should I look for a casino bonus?

    When signing up to a new casino, a great way to get the most out of your deposit is by finding a great casino bonus. Look for the highest amount and lowest wagering requirements out there. It’s also important to note that some casinos can offer different terms for different payment methods.

  • Is there such as thing as free sign up bonus?

    Yes, there is! Several casinos let you start playing without making a single deposit, and still take out real money winnings. This is called a no deposit bonus, which normally consists of up to 50 bonus spins. You can find the best no deposit bonus offer from top UK online casinos.
