What is a casino bonus?

A casino bonus is a reward that casinos offer to their players, most commonly as a welcome bonus or sign-up offer when making their first deposit. However, bonuses aren’t just for new players, many casinos continue to offer promotions to keep their existing customers happy as well.

Casino bonuses come in different forms, such as:

  • Deposit Match: The casino matches your deposit up to a certain amount (e.g., 100% up to £100).
  • Free Spins: A set number of spins on selected slot games (e.g., 100 free spins on Big Bass Bonanza).
  • Cashback: A percentage of your losses returned as cash or bonus funds.
  • Bonus Combinations: Some casinos offer a mix of bonuses, like 100% up to £100 + 100 free spins.

How rate casino bonuses

While we consider many factors when rating casino sites, including the welcome bonus as part of the overall score, when determining the best bonus (as is the purpose of this page), we focus only on bonus-related factors.

Since a casino must meet our strict criteria just to be featured on our site, we’re not simply highlighting casinos with great bonuses that fail to meet our other standards. These casinos excel in multiple areas, but here, we evaluate specific bonus factors to determine which ones are the best for different preferences such as free spins, cashback and deposit match bonuses.

Type of bonus

Is it a matched deposit bonus, free spins, cashback, or even a live casino bonus? The type of bonus doesn’t necessarily determine whether it’s good or bad, but it does matter based on your preferences. If you enjoy slots, free spins might be the best choice, while a matched deposit bonus gives you more flexibility. Some casinos also offer a combination of bonuses, like matched deposit + free spins.

Bonus amount

One of the most important factors is how much extra we’re actually getting from the casino. While the type of bonus doesn’t determine this, the matched deposit + free spins combo generally offers the highest bonus amount. The more we get, the better, although a major caveat to this is the terms and conditions that apply. This factor is especially important for high rollers who deposit larger sums. However, if you usually deposit the minimum amount, such as £10 or £20, the overall bonus size may not matter as much.

Wagering requirements

We’d argue this is the most important factor to consider, and we’re very transparent about highlighting it in our lists. The wagering requirement determines how much you need to play through before the bonus turns into real money, so the lower, the better.

  • 35x – standard wagering requirement
  • 30x or below – low wagering requirement
  • 40x or higher – high wagering requirement

For example, if you deposit £100 and receive a £100 bonus, a 35x wagering requirement means you’d need to wager £3,500 before cashing out. You can read more about how wagering requirements work here.

Expiry

Expiry refers to the time limit for wagering your bonus or using your free spins. Typically, casinos allow between 7-30 days to meet the wagering requirements, which is a reasonable timeframe. However, some casinos offer less time, so it’s important to check the expiry period to avoid losing your bonus. Free spins usually have a shorter expiry than matched deposit bonuses, sometimes as little as 24 hours.

Max cashout

Ever played with a bonus and won big, only to realize you can’t withdraw your full winnings? We’ve been there, and it’s frustrating. Some casinos impose a cap on how much you can win from a bonus, either as a fixed amount like £5000 or as a multiple of your deposit, such as 10x your deposited amount.

Eligible deposit methods

You don’t want to deposit at a casino expecting a bonus, only to find out your payment method doesn’t qualify. It might sound strange, but it’s a common pitfall. Popular options like Skrill and Neteller are often excluded, and sometimes even Paysafecard and others. Casinos do this to protect themselves from bonus abuse, as these methods have been linked to it. It’s unfortunate because they’re usually among the fastest deposit and withdrawal options, which is something we appreciate.

Game limitations

While bonuses must be wagered a certain number of times, not all games contribute equally to the turnover. Slots generally count 100%, meaning every £1 staked on a slot gets you £1 closer to meeting the wagering requirement. Other games contribute less, for example:

  • Slots: 100%*
  • Live casino games: 10%
  • Video poker: 5%

*As if there weren’t already enough limitations, some slots are completely excluded and count 0% toward the wagering requirement. Each casino provides a list of these excluded slots, but it’s often not easy to find. While the specific slots vary from casino to casino, they usually fall into one of two categories:

Slots with high RTP – High RTP slots make it easier to wager the bonus before losing your balance. That’s why some of these, like Blood Suckers, Book of 99, and 1429 Uncharted Seas, are often excluded. However, if you find a high RTP slot that isn’t on the excluded list, we recommend playing it to maximize your chances of clearing the bonus.

Slots with high max wins – Some slots offer insane max wins, which can be costly for casinos if won with bonus money. While they accept the risk when players use their own funds, they often exclude these high-payout slots from bonus play. That’s why games like Dead or Alive 2, Starburst XXXtreme, and Money Train 3 frequently appear on exclusion lists.

Make sure to check if the slot you’re playing actually counts toward the wagering requirement before you start.

Minimum qualifying deposit

Almost every bonus requires a deposit to be claimed, unless it’s a no deposit bonus. However, the minimum deposit amount needed to qualify for a bonus varies between casinos. In most cases, it’s either £10 or £20.

If you usually deposit more than this, it shouldn’t be a concern (though we always recommend double-checking). But if you prefer playing with smaller amounts, it’s important to check this to avoid any surprises.

Also, note that the minimum deposit a casino accepts and the minimum qualifying deposit for a bonus aren’t always the same. A casino might allow raw money deposits as low as £5 or even £1, but to claim a bonus, you may need to deposit at least £10 or £20.

The Best Casino Sign-Up Offers

In the UK, we have many excellent online casinos competing to be the best and to have the best casino bonus on the market. The bonuses available right now vary greatly. Some offer percentage bonuses, some offer free spins, some offer cashback, and sometimes a combination of these.

What our expert says:

So, what's the best casino bonus? Is it the bonus with the highest amount or the lowest wagering requirements? There's no absolute truth; it depends on both your budget and your goals. If your goal is to play through the bonus without making a huge profit, it might be smarter to take advantage of bonuses of 300%, 400%, or even 500% and deposit a smaller amount. On the other hand, if you want to make a larger profit, you should deposit more money to make it possible. A low wagering requirement is also always preferable. So, a combination of a bonus over 200% and a low wagering requirement is really good. Here are some of our favorites.

No wagering bonuses

By now, you’ve probably realised that wagering requirements play a huge role in the value of a casino bonus. But what if we told you there are bonuses with no wagering requirements at all? That’s right, no wagering bonuses mean you can withdraw any winnings directly, without having to play through the bonus X amount of times.

For obvious reasons, the bonus amount is usually lower than bonuses with wagering, but there’s nothing to lose in claiming them.

Currently, PlayOJO is the only casino offering a free spins bonus with no wagering.

Deposit match bonuses

A matched deposit bonus is the most common type of casino bonus. It means the casino will match your deposit up to a certain amount, for example, 100% up to £100. These bonuses almost always come with wagering requirements, which are important to check.

What's crucial to understand is how the wagering requirement is applied. It could be based solely on the bonus amount (e.g., £100 in our example), or sometimes, it applies to both the deposit and the bonus combined, meaning £200 in our example.

For instance, if the wagering requirement is 35x, you’d need to wager either £3,500 (if the requirement is just for the bonus) or £7,000 (if it includes the deposit). That’s a huge difference, so always check the terms carefully.

What does 100% up to X mean?

The phrase "100% up to £100" (or any other common matched deposit bonus) doesn’t mean you need to deposit the full amount to receive the bonus. Usually, the minimum deposit required is either £10 or £20, which will then be matched with an equal amount of bonus money.

You can also deposit more than £100, but the bonus will still be capped at £100. Here’s how it works:

Cashback bonuses

Cashback bonuses are ideal for high rollers or players who play frequently. While these bonuses aren’t as common as they once were, they offer a percentage of your losses back, typically on a weekly or monthly basis, depending on the casino’s terms.

Cashback can either be paid as bonus money (with some wagering requirements attached) or as cash with no restrictions. A common offer is 10% cashback on your losses. For example, if you lose £100 in a week, you could get £10 back to use for further play or withdraw, depending on the terms. 

If you play a lot and lose £1,000, a 10% cashback bonus would give you £100 back. This makes it potentially more valuable for high rollers than a matched deposit bonus, especially if the bonus amount is limited (e.g., £100 or £200). With a cashback bonus, the more you lose, the more you can earn back, making it a great option for frequent players.

Slot bonuses

Most casino bonuses are good if you want to play slots. Whether it’s free spins on a specific slot or extra cash to play on your favourite game, a sign up offer gives you more to play with. 

You can use any of the bonuses on our list to play slots. However, keep in mind that some bonuses restrict certain slots from counting towards the wagering requirements. Always double-check the terms and conditions so that you’re not playing excluded games.

Are casino bonuses worth claiming?

Yes, welcome bonuses can be worth claiming, especially if you plan to play for a long time. While most bonuses have a negative Expected Value (EV), this is also true when depositing raw money, the house always has an edge.

However, bonuses give you more playtime and more chances to hit big wins before busting. This can make them worth your while if your goal is big wins, rather than short-term cashouts.

Let’s compare playing with a bonus vs. playing with raw money, using a common 100% up to £100 bonus with 35x wagering, assuming you play slots with 96% RTP.

Scenario 1: Playing with a bonus (£100 deposit, £100 bonus, 35x wagering requirement)

  • Total balance to start: £200 (£100 deposit + £100 bonus)
  • Wagering requirement: £100 × 35 = £3,500
  • Expected loss: £3,500 × 4% = £140
  • EV Calculation:
    • Bonus: £100
    • Expected loss: -£140
    • Total EV = £100 - £140 = -£40

On average, you will end up with a £60 balance from your £100 deposit, but variance means you could either bust or win more.


You must complete wagering before cashing out, which increases the risk of losing everything before withdrawing.

Scenario 2: Playing without a bonus (£100 raw deposit only)

  • Total balance to start: £100 (no bonus, just deposit)
  • No wagering requirement (can cash out at any time)
  • Expected loss:
    • If you wager the full £100 once, expected return = £100 × 96% = £96
    • If you keep wagering like in the bonus case (35x turnover), expected loss = £140
    • Balance left: -£40 (bust before completing 35x wagering)

Without a bonus, you can stop at any time and cash out, meaning you control your risk better.


If you don’t want to be locked into a long play session, raw money is the better choice.

For the EV to be positive, a casino bonus needs to have a wagering requirement of 25x or lower (for a 100% up to £100 bonus, playing 96% RTP slots). If you can play slots with higher RTP you will have positive EV even if the wagering requirement is higher.

For the bonus to be +EV, you should play slots with an RTP of at least:

  • 97.14% for 35x wagering
  • 96.67% for 30x wagering

When should you take a bonus?

Take a bonus if:

  • You plan to play longer and want more playtime.
  • You enjoy taking risks for bigger potential wins.
  • You play high-RTP games (with 100% wagering contribution) to maximize EV.

Avoid a bonus if:

  • You want to cash out at any time.
  • You prefer short-term, low risk play.
  • The wagering requirement is too high.

Bonuses increase playtime and can improve your odds of winning before busting. However, they also lock you into wagering requirements that can lead to losing everything before cashing out. Whether it’s worth it or not is up to your preference, we hope this can help shed some light on what to look for.

How to claim a casino bonus

In this guide, we'll tell you how to create a new account at a casino and take advantage of a new casino bonus. What you need to get your new casino welcome bonus is:

A computer, tablet, or mobile phone
Internet access
At least £10 (or the qualifying minimum deposit)
Time required: Creating a new account at an online casino takes about 5 minutes.

1. Find and choose a new casino bonus

When it comes to casino bonuses, there are plenty of casinos and bonuses to look through. That's where we come in. We've gathered all the bonuses on this website at casinos with a UK gambling license and provide you with both a long list of all casino bonuses and our top lists of the bonuses we think are the best! If you want even more information about the casino sites, you can read our reviews. Just click on the casino, and the review will appear.

2. Sign up with a casino and get the casino bonus

Once you've chosen a casino, it's time to sign up to claim the bonus. Click on our bonus link, and you'll always get the latest updated bonus. Most online casinos now have a simple and quick registration process that only requires you to enter a few personal details.

3. Wager your casino bonus

Some casino bonuses require wagering to receive the full welcome bonus. Read the terms carefully and check out our review where we delve a bit deeper into the bonus terms. Then, just start playing and wager your bonus at a reasonable pace.

4. Withdrawals and winnings from the casino bonus

Most casinos accept the most common payment methods, such as debit card or bank transfers. But some also have even more payment methods to choose from, so it's worth checking before you start so you know exactly which payment methods you'll be using and which payment methods the casino accepts. In some cases, a method may be accepted for deposit but not for withdrawal, although this is rare. When it comes to withdrawals, we believe it's important to reward yourself with a withdrawal sometimes too.
