Comparing the Best Casino Bonuses

When choosing an online casino, bonuses play a significant role in enhancing your gaming experience. Below, you'll find a comprehensive table comparing the best casino bonuses available, making it easier to evaluate and select the one that suits your preferences and gameplay style.

Online Bonus Categories

Below we're going to break down what some of these 'bonus buzzwords' mean, so next time you come across them, you'll know how to navigate them like a pro.

Welcome Bonus

A welcome bonus is a promotional offer online casinos use to attract and reward new players when they sign up and make their first deposit. It boosts newcomers, allowing them to explore the casino's games with more cash behind them. Typically, the most common type of welcome bonus is a deposit match, where the casino matches a percentage of the player's initial deposit or minimum deposit, often 100%, up to a specified limit. For example, if a casino offers a 100% match up to £100 and a player deposits £50, the player would receive an additional £50 in bonus funds, giving them £100 to play with. This is just one example of a welcome bonus, but the casino welcome bonuses will differ depending on the casino!

Play Value Calculation

Example: 100% match up to £100; £50 deposit, 30x wagering.

Calculation:

• Worst-case: Expected loss based on wagering requirements:
  Bonus funds: £50.
  Wagering: £50 × 30 = £1,500.
  Loss (96% RTP): £1,500 × 4% = £60.
  Play Value (Worst Case): £50 - £60 = -£10.
• Best-case: Win enough to meet wagering without additional loss.
  Play Value (Best Case): £50 (full bonus retained).

Range: -£10 to £50.

No Deposit Bonus

A no-deposit bonus is a casino promotion that allows players to receive bonus funds or free spins without making an initial deposit. Essentially, it's a way for players to try out the casino's games for free, while still having the chance to win real money. Typically, the bonus is offered upon registration, and the funds or spins can be used on selected games. As mentioned in the welcome bonus, any winnings from a no-deposit bonus are often subject to wagering requirements, meaning players must bet a certain amount before withdrawing any potential winnings.

Play Value Calculation

Example: £10 bonus with 40x wagering.

Calculation:

• Worst-case: Loss from wagering:
  Wagering: £10 × 40 = £400.
  Loss (96% RTP): £400 × 4% = £16.
  Play Value (Worst Case): £10 - £16 = -£6.
• Best-case: Win maximum allowed without exceeding wagering limits.
  Play Value (Best Case): £10 (no loss).

Range: -£6 to £10.

Free Spins

Free spins are a popular casino bonus that allows players to spin the reels of a slot game without using their own money. You'll often find them offered as part of an online casino's welcome package or promotional deal. These free spins provide a set number of spins on a specific slot game. Players can still win real money from free spins, but the winnings are often credited as bonus funds, which of course, will come with certain wagering requirements. Free spins are a great way for players to explore new games and keep playing for bonus bets without any risk.

Play Value Calculation

Example: 50% match up to £100; £50 deposit, 30x wagering.

Calculation:

• Worst-case: Loss from wagering:
  Bonus funds: £25.
  Wagering: £25 × 30 = £750.
  Loss (96% RTP): £750 × 4% = £30.
  Play Value (Worst Case): £25 - £30 = -£5.
• Best-case: Meet wagering with no losses.
  Play Value (Best Case): £25 (full bonus retained).

Range: -£5 to £25.

Reload Bonus

A reload bonus is a promotion offered by online casinos to reward existing players for making more deposits after their initial one. Unlike a welcome bonus, which typically applies to new players, a reload bonus encourages players to keep playing at the online casino by matching a percentage of the player’s deposit. For example, a casino might offer a 50% reload bonus on deposits made during the weekend, giving players extra funds to enjoy their favourite games.

Play Value Calculation

Example: 50% match up to £100; £50 deposit, 30x wagering.

Calculation:

• Worst-case: Loss from wagering:
  Bonus funds: £25.
  Wagering: £25 × 30 = £750.
  Loss (96% RTP): £750 × 4% = £30.
  Play Value (Worst Case): £25 - £30 = -£5.
• Best-case: Meet wagering with no losses.
  Play Value (Best Case): £25 (full bonus retained).

Range: -£5 to £25.

No Wagering Bonuses

A no-wagering bonus is a casino promotion that allows players to keep their winnings without any wagering requirements. Unlike traditional bonuses, which require players to bet a multiple of the bonus amount before withdrawing, no wagering bonuses mean you can access your winnings immediately! For example, if you get a £50 no-wagering bonus and win £30, you can withdraw the full £30 without any additional requirements. This kind of bonus is great for players who want a hassle-free online casino gaming experience, as the cash will go instantly into your selected payment method.

Play Value Calculation

Example: £50 bonus with no wagering.

Calculation:

• Worst-case: No winnings (bonus used but no gains).
  Play Value (Worst Case): £0.
• Best-case: Full bonus used effectively as withdrawable cash.
  Play Value (Best Case): £50.

Range: £0 to £50.

Cashback Bonus

A cashback bonus at a casino is a promotional offer that returns a percentage of a player’s losses over a specified period, typically either every week or every month depending on the online casino. For example, if an online casino offers a 10% cashback bonus and you have made losses of £100 during the promotional period, you would receive £10 back as bonus funds. This type of bonus provides players with a safety net, meaning they can win money back and continue playing casino games. Cashback bonuses often come with specific terms and conditions, including wagering requirements, so always review these before participating in a cashback bonus.

Play Value Calculation

Example: 10% cashback on £100 losses.

Calculation:

• Worst-case: Cashback is the only recovery from losses.
  Play Value (Worst Case): £10 (cashback).
• Best-case: Cashback is additional to unexpected wins.
  Play Value (Best Case): £10 + potential winnings.

Range: £10 to Variable (based on winnings).

VIP Bonuses

A VIP bonus is an exclusive promotion online casinos offer to reward their most loyal players. These bonuses can take lots of different forms, including higher deposit match percentages, personalised cashback offers, free spins, or even invitations to special events and tournaments. VIP bonuses often come with fewer wagering requirements and more flexibility compared to the standard promotions at an online casino. At some casinos, VIP players can enjoy dedicated account managers, make use of instant withdrawal casinos, and tailored rewards based on their preferred gaming style. This premium treatment aims to encourage loyalty among players and encourage continued play to their valued customers!

Play Value Calculation

Example: £200 bonus with 20x wagering.

Calculation:

• Worst-case: Loss from wagering:
  Wagering: £200 × 20 = £4,000.
  Loss (96% RTP): £4,000 × 4% = £160.
  Play Value (Worst Case): £200 - £160 = £40.
• Best-case: Minimal losses or full bonus retained.
  Play Value (Best Case): £200.

Range: £40 to £200.

Sticky Bonuses

Sticky bonuses, also known as non-withdrawable bonuses, are tied to your account and cannot be cashed out. While they give you more funds to play with, the bonus amount is deducted when you request a withdrawal. For example, if you receive a £100 sticky bonus and win £200, only £100 of the winnings can be withdrawn. These bonuses are ideal for players looking to maximise their gameplay without focusing on withdrawing the bonus itself.

Play Value Calculation

Example: £100 bonus; winnings capped at £200.

Calculation:

• Worst-case: No withdrawable winnings beyond the sticky bonus.
  Play Value (Worst Case): £0 (loss).
• Best-case: Max withdrawable winnings:
  Play Value (Best Case): £200 (minus sticky bonus).

Range: £0 to £100.

Non-Sticky Bonuses

Non-sticky bonuses, also called withdrawable bonuses, let you play with your real money first and the bonus funds only after your deposit is spent. This means you can withdraw any winnings earned with your real money without affecting the bonus. For instance, if you deposit £50 and win £100 before using the bonus, you can withdraw your winnings immediately. These bonuses offer more flexibility and are preferred by players who prioritise cashing out their profits.

Play Value Calculation

Example: £50 deposit, £50 bonus.

Calculation:

• Worst-case: Deposit lost without triggering bonus funds.
  Play Value (Worst Case): £0.
• Best-case: Winnings from deposit before bonus kicks in.
  Play Value (Best Case): Unlimited potential (depends on game).

Range: £0 to Variable.

How Casino Bonuses Work

A deposit match bonus is one of the most popular promotions offered by online casinos. This type of bonus works by matching a player's initial deposit with bonus funds, giving them extra money to play with. Let’s break down how this works at BetMGM using a typical offer as an example.

BetMGM offers a 100% deposit match bonus of up to £100. If you deposit £50, the casino will match that amount, giving you an additional £50 in bonus funds. This means you’ll have £100 total to play with. Similarly, if you deposit the full £100, you'll receive £100 in bonus funds, doubling your balance to £200. The same principle applies if you deposit less: for example, depositing £20 would give you £20 in bonus funds, leaving you with £40 to use.

Alongside deposit match bonuses, BetMGM will also offer free spins on popular slot games. For example, you can receive 50 free spins on a featured slot like Starburst as part of the welcome package. These free spins allow you to play the game without using your own money, while still having a chance to win real money. Any winnings from the free spins are often credited as bonus funds and subject to wagering requirements, so make sure to read the terms and conditions before playing.

It’s important to note that both the bonus funds and free spins come with wagering requirements, which means you’ll need to wager the bonus amount a certain number of times before you can withdraw any winnings. For example, if the wagering requirement is 20x, you’ll need to bet the total amount of the bonus 20 times before cashing out.

What to Look For in a Casino Bonus

When choosing a casino bonus, consider key factors to ensure you get the best value and experience. Whether it’s access to more games, free spins, or extra bonus bets, these elements are crucial before spending your money. Below are the main points to evaluate when selecting a bonus.

Wagering Requirements: These determine how many times you need to play through the bonus before withdrawing winnings. Lower requirements (e.g., 20x) are more favourable than higher ones (e.g., 50x).

Bonus Validity Period: Bonuses have time limits for use and meeting wagering requirements. Short periods (like 7 days) can be restrictive, while others may allow up to 60 days. Always check the terms.

Game Contributions: Not all games contribute equally to wagering requirements. Slots often count 100%, but table games may only contribute 10%. Check how your preferred games factor in.

Maximum Win Limits: Some bonuses cap winnings from bonus funds. If a cap exists, you can’t withdraw more than the limit, even if you win more. Always check for this restriction.

Deposit Match Percentage: The percentage at which your deposit is matched affects the bonus size. A 100% match doubles your deposit, while a 50% match gives half. Look for higher percentages for better value.

Eligible Payment Methods: Some bonuses exclude deposits via certain payment methods like PayPal or Skrill. Check the qualifying methods to ensure your deposit counts.

Which Bonus is Right for You

It can be tricky to select which casino to bonus to choose. It is important to take a look at every offer available to you and consider beforehand what it is you are looking for. Choosing the right casino bonus often depends on your goals and experience. Beginners may prefer simple bonuses like no-deposit or free spins to explore games without risk, while experienced players might opt for deposit matches or reload bonuses to maximise their funds. Consider wagering requirements—low or no wagering is ideal for easier withdrawals, while higher requirements may suit those seeking larger rewards.

Think about your favourite games; slots often contribute 100% to wagering, whereas table games may contribute less. Check for time limits and maximum win caps, as shorter validity or capped winnings might not align with your goals. For steady play, cashback bonuses can offer consistent value by returning a portion of your losses. Tailor the bonus to your play style and budget to get the most out of your casino experience.

Which Casino Payment Methods can you use in the UK?

There are a wide range of payment methods from debit cards to e-wallets available at the majority of UK casinos. Which payment method is best is subjective and depends on what you prioritise. Maybe you prefer payment methods that allow for fast withdrawals or maybe you prefer paying more securely and without having to give your bank details. Take a look below as we analyse every payment method available to you at UK casinos.

Debit Cards

Debit cards like Visa or Mastercard are UK casinos' most commonly used payment method. One of the main reasons for this is that debit cards typically qualify for most casino bonus offers, unlike some other payment methods, such as PayPal, which are often excluded. When using a debit card, deposits go through immediately, while withdrawals often take around a day to process, which is slightly longer than other payment methods.  Debit cards are also widely used as they are a safe and secure payment method. However, a downside of using debit cards is that your bank can see what you are doing, so there is less privacy compared to other payment options.

Apple Pay

Apple Pay is a popular payment method mainly due to its convenience. Depositing money takes seconds, and once it is done, it will reach your casino account immediately. Withdrawals are also very quick, with some sites allowing instant withdrawals on Apple Pay. Make sure to check whether Apple Pay deposits qualify for a casino’s sign-up offer, as some casinos may exclude Apple Pay. Although Apple Pay is quickly growing in popularity, it is not accepted at all UK casinos.

PayPal

Another payment method that is growing in popularity is PayPal. PayPal is the number one e-wallet used to deposit and withdraw money at UK casinos. The main attraction of PayPal is the added layer of privacy and security that is achieved by using e-wallets. By using PayPal, customers do not need to give their banking information to the casino, which helps protect and secure their private information. PayPal is also growing in popularity due to the quick transactions it offers. Transactions are often instant, and there are typically no transaction fees. Most UK casinos accept PayPal as a payment method. However, they often do not allow deposits from PayPal qualify for their sign-up offers.

Alternative E-Wallets

Alternative e-wallets like Skrill and Neteller are also popular choices for depositing and withdrawing funds at UK casinos. These e-wallets offer a high level of privacy and security, as they act as an intermediary between your bank and the casino, keeping your financial details confidential. Just like PayPal, one major benefit of Skrill and Neteller is the speed of transactions, with deposits being instant and withdrawals often processed much faster than traditional methods. While widely accepted at online casinos, it’s worth noting that deposits made with Skrill or Neteller often do not qualify for welcome bonuses or other promotional offers, which can be a drawback for some players.

Bank Transfer

Although not a very popular method compared to others, bank transfers are an efficient and extremely secure way of depositing and withdrawing money into your UK casino account. Bank transfers allow you to transfer funds into your casino account directly from your bank. They are a very safe and secure method of transferring money. However, this means that your bank will know what you are spending your money on, which some see as a drawback. As well as this, bank transfers take much longer to process transactions, so it could take up to 3 days for your funds to be transferred.

Sign Up Bonuses vs Existing Customer Bonuses

Sign-up bonuses and existing customer bonuses differ in several key ways. Sign-up bonuses are exclusively available to new customers, while existing customer bonuses are open to all players, whether new or returning. Sign-up offers are typically more generous as casinos aim to attract new players, but existing customer bonuses often provide excellent value as well, frequently requiring no deposit to claim.

Sign-up bonuses are heavily advertised and easy to find, appearing on casino homepages and websites like BettingOdds.com. In contrast, existing customer bonuses are usually located on the promotions page of a casino’s website or app, offering ongoing rewards for loyal players.

Seasonal and Niche Casino Bonuses

Some casinos offer seasonal and niche bonuses to either new customers as a sign up bonus or existing customers for anyone to enjoy. Take a look below at some good examples of seasonal and niche bonuses.

• Christmas Free Spins: Often UK casinos offer players some free spins as a Christmas gift
• Black Friday Cashback: To celebrate Black Friday, some casinos may offer players a cashback percentage on all losses for the day
• Summer Giveaways: Casinos may run summer-themed campaigns offering deposit matches, free spins, or prize draws for holidays

The Legal Landscape of Casino Bonuses in the UK

The UK Gambling Commission (UKGC) regulates casino bonuses to ensure they are fair and transparent. All online casinos in the UK must clearly display bonus terms, including wagering requirements, time limits, and game restrictions. Misleading advertising, such as hiding key details, is not allowed.

Casinos cannot change bonus terms after a player has opted in and must let players withdraw their real-money balance without losing their bonus. These rules are in place to protect players, ensure bonuses are easy to understand, and deliver what they promise.

Summary

Our guide will help you find the best casino bonuses in the UK. Whether you’re interested in exploring online slots or live casino games, it’s important to choose a bonus that fits your preferences. Remember, different games contribute differently toward bonuses, so always check the terms and conditions. From free spins to sign-up bonuses, there’s something for everyone—just take the time to find the best option for your gaming needs.
