What are Online Casino Bonuses?

If you are looking to join an online casino and extend your playing cash, then online casino bonuses are a great way to boost your gameplay. They are credited to your account upon registration and usually come in the form of cash, free/bonus spins or both.

The most popular casino bonus is a deposit match bonus that is offered to you as part of a welcome package or a special promotion. Think of it as a nice welcoming cup of tea and biscuits on arrival to the site.

The best thing about a casino bonus is that it’s easy to claim. All you have to do to receive the bonus is to find a good deal, register with the casino and make your first deposit. You can always use our up to date casino reviews page to find the best bonuses for UK players.

Types of Online Casino Bonus

A welcome bonus is a good way for you to have a taste of what a casino has to offer along with some extra cash or spins to kick things off. The interesting thing is that it could come in many different forms, most of which we’ve covered below.

1. Bonus with deposit required

A deposit bonus is one of the most popular casino bonuses and is awarded to you when you make your first deposit. It usually looks something like this: 100% up to £100 and means that your first deposit will be doubled. Deposit £50 play with £100. Not bad, huh?

When casinos feel generous, they can give you a layered match bonus where you can claim your casino’s bonus via multiple – 1, 2, 3, 4 and even 5 – deposits. Often, that’s a great offer, because by using the first deposit, you can dip your toes in the waters of the casino to see if you like it.

Another type of deposit works by having a predefined amount of bonus cash given with free spins or bonus spins. For example, 100% up to £100 + 50 free/bonus spins. That’s a great offer because, on top of your match bonus amount, you can also use these extra spins on preselected slots.

2. No deposit bonuses

A no deposit bonus is a great bonus and does what it says – awards you a bonus without having to make a deposit. In this case, you can either claim free cash, free spins or bonus spins.

3. Free Spins

As we’ve briefly mentioned above, free spins or cash spins can come as a no deposit bonus or part of a casino’s welcome offer. They can be used to play slots without having to spend your own cash. Previously all kinds of spins were called free spins whether they came with the wagering requirements on not. Today, due to strict UKGC regulations, only wager-free spins can be called free spins.

4. Bonus spins & extra spins

Just like free spins, you can use bonus spins and extra spins to play slots without spending your own money. And they too can be offered as part of a casino’s welcome deal or a no-deposit bonus offer.

What differentiates free spins from bonus spins is that bonus spins have wagering requirements attached to them. Following the UKGC guidelines, casinos are required to advertise free spins as bonus spins if they come with any wagering requirements. But, and here is the best part, once you fulfil the wagering requirements you get to keep the winnings.

5. Other types of bonuses

The above are some of the most popular casino bonuses, but there are a few more types of bonuses that you might come across at online casinos.

• Cashback bonuses
• Reload bonuses
• High Roller bonuses
• VIP bonus
• Refer a friend bonus

6. Seasonal bonus promotions

These refer to all bonuses that are being offered by casinos only during a special event or a holiday. Seasonality is very important here, because the bonuses usually stop being active after the holiday is over. Such bonuses include Halloween slot bonuses, Black Friday casino bonuses, and Christmas bonuses.

How to Get Casino Bonuses Online

One way to get a generous casino bonus online, if you are a new player, is to join a casino and claim their welcome bonus or no deposit bonus. But what about the returning customers?Great news. Most online casinos have regular promotions running to satisfy their loyal players. Cashback and reload bonuses being the most popular among UK casinos. Here’s how each of the bonuses can benefit you.

Casino Welcome Bonus/Sign-up Bonus

Welcome bonus is exclusively reserved for new players. To claim a no deposit welcome offer, all you have to do is sign up to a casino by completing the registration process. You might have to enter a bonus code, but you won’t have to deposit.

Otherwise, the welcome bonus will require a deposit. You can get a sign-up package that will give you bonus money and free spins over several deposits! A lot of UK casinos have this type of offer for new players. The most common welcome deposit bonus is a 100% match bonus.

Reload Bonus

Otherwise known as a deposit bonus, a reload bonus can be given to you after you’ve claimed your welcome offer. In other words, it’s an incentive for you to make a further deposit. Think of it as a deposit bonus, but smaller.

Reload bonus amounts differ from site to site and always change. To keep up with the new offers, you could either subscribe to the casino’s promotional emails or opt-in to their SMS service. That way you’ll stay up to date with the best deposit bonuses. Because, ultimately, you want to claim more bonus money. The more you have to play with, the more cash you could potentially win.

A reload bonus is here to keep you happy and loyal to the casino. But beware that it’s a time-sensitive bonus. Therefore, to claim your bonus money you’ll need to deposit within a certain time frame.

Cashback

Cashback is a great way for you to win some money back on your losses. Depending on your status at the casino, you could receive a real money cashback bonus.

It’s usually based on your total losses over a certain time (i.e., a week) and determined by a fixed percentage. The average cashback percentage varies from site to site, but commonly it sits between 5% and 25%.

For example, a casino might include a 5% cashback offer on losses made on a particular day, as long as your balance is at £0. So, if you played £100 that day and lost it all, you could earn £5 cashback.

Popular T&Cs and How to Choose the Best Casino Bonuses

Choosing the best casino bonuses can be a little tricky at times. It’s not enough to pick a casino with the highest bonus on offer. Because the biggest bonus doesn’t always mean a good bonus.

That’s not to say that it can’t be a good deal, but it can come with lots of restrictions and risks. In most cases, if a bonus looks too good to be true it probably is. You want to look out for those casino bonuses that have reasonable terms and conditions attached and can extend your gameplay. Here are the most popular T&Cs that you should pay attention to before accepting a bonus:

Wagering Requirements

Let’s talk about wagering requirements. The majority of welcome bonus offers at UK casinos come with wagering requirements attached to them. It can be anything from as low as 10x up to a whopping 60x and higher.

• Typically, a standard wagering requirement will be between 20x and 35x.
• Anything above 35x would be high wagering. The higher wagering requirements will usually apply to a bigger 300%, 400% or 500% bonus.

Sometimes you’ll come across a deposit bonus with no wagering. The downside of such a bonus is that you can’t always withdraw it but it’s still a great way for you to have fun and experience the casino.

The most confusing part of the wagering requirements is the difference between wagering just the bonus vs wagering bonus + deposit. The main distinction here is that you’ll have to wager the bonus amount only or the bonus + deposit amount respectively. Have a look at the below examples.

Wagering the bonus only:

• Example offer: No deposit £10 bonus on registration
• Wagering requirement: 45x
• Your winnings: X
• Calculation: £10 (bonus money) x45 = £450
• Explanation: To withdraw your X amount of bonus money, you’ll need to wager your bonus 35 times. This means that you’ll have to bet £450 before you can withdraw your X bonus winnings.

Wagering both bonus + deposit:

• Example offer: 100% up to £100
• Wagering requirements: 35x bonus + deposit
• Your deposit: £50
• Your winnings: X
• Calculation: £100 x 35= £3,500
• Explanation: To cash out your X winnings, you’ll need to wager both £50 deposit + £50 bonus 35 times before you could make a withdrawal. This means you’ll have to bet £3,500 to collect your winnings.

Similarly to bonus funds, any winnings from bonus spins will also be tied to similar wagering requirements before you can withdraw your winnings.

Bonus spins example:

• Example offer: 30 bonus spins
• Wagering requirements: 35x
• Your deposit £10
• Your winnings from bonus spins: £60
• Calculation: £60 (winnings from spins) x 35 = £2,100
• Explanation: To withdraw your winnings from bonus spins, you’ll need to bet £2,100. It might look like a big amount to bet until you can withdraw, but remember that you keep on winning as you spin.

Restricted Games

It’s very rare for a casino to allow you to play your bonus cash on any games you like. You’ll mostly have the titles preselected for you by the casino. The reasons for it are endless. Maybe they want to promote a new game from a certain game provider or encourage you to play games that offer a higher value per spin.

Either way, the number of games you can play with your bonus will be listed in the general terms or conditions or the bonus terms so be sure to check them out.

Bonus Codes

Some bonuses require bonus codes to be entered during the deposit process. Without entering the correct code, the bonus won’t be activated.

Time Limits

Many bonuses come with an expiration date, meaning you have to use the bonus and fulfil any wagering requirements within a set period, such as 30 days.

Bet Limits

There’s often a cap on how much you can bet per round or spin when playing with bonus funds. Exceeding this limit can violate the terms and lead to the forfeiture of the bonus and any winnings.

Cash-out limits

It’s for a good reason we keep banging on about the importance of reading the bonus terms and conditions upfront. Knowing your bonus cash out limits is important because the rules set by the casino can limit the bonus amount you can withdraw.

Most casinos will have a set maximum amount you can withdraw regardless of how much you win with your bonus cash. So, if you happen to win a jackpot of £500 when playing on bonus and the cashout limit determined is £300, you’ll only be able to withdraw the £300 and not a penny more.

Having a VIP status at a casino often involves higher withdrawal limits so you might want to check the perks and terms of becoming one.

Needless to say, casinos with higher cash out limits are the most attractive. But, at the end of the day, you need to look at the whole package.

Payment Methods

One thing to look out for when joining a casino and making your first deposit is payment methods. Each casino will have their list of deposit and withdrawal methods which you can access via the terms and conditions or FAQs page. Some of the most popular include bank cards, e-wallets, prepaid cards and bank transfers.

Usually, you’ll be able to withdraw your bonus winnings via the same method you deposited with. But beware when claiming your match deposit bonus. In many cases, deposits with Skrill, Paypal, Neteller and Paysafecard are not eligible to claim a welcome bonus.

Other Requirements

When choosing the best casino bonus, also look out for other requirements including minimum deposit requirements, restricted countries, forbidden betting patterns etc.

You’ll always find them stated in the casino’s general terms and conditions.

Here’s a Quick Checklist For Choosing The Best Online Casino Bonuses:

🗸 Check the bonus and general terms. You want them to be fair with reasonable wagering requirements.

🗸 Some of the best casino bonuses that give free bonus cash and can extend your gameplay are no deposit bonuses or bonus spins.

🗸 Check if a casino has a mix of bonuses for both budget-conscious players and high rollers.

🗸 You want casino bonuses with a high winning cap and good time limits for longer gameplay.

🗸 Look out for bonuses that can be used on a wide selection of slots.

What is Bonus Abuse?

Bonus Abuse is the term used to describe taking advantage of bonus offers from online casinos without intending to play fairly. This behaviour is against the rules and regulations established by the casino and can result in penalties like confiscated wins, account suspensions, or even permanent bans. The following behaviours are examples of bonus abuse, however, they’re not the only ones:

• Multiple Accounts: Creating numerous accounts to redeem the same bonus more than once.
• Syndicate Play: Working together with other players to take advantage of bonus offers or fulfil wagering requirements.
• Betting with Minimal Risk: Making low-risk wagers merely to satisfy the wagering requirements. For instance, in roulette, placing bets on both red and black.
• Bonus Stacking: The practice of using several bonuses at once without first meeting the requirements for each one.
• False Information: Entering fictitious personal information when registering to receive a bonus.
• Claim Bonuses Sequentially: Constantly registering for new bonuses without making regular deposits or playing games between them.

Casinos keep a watchful eye on player behaviour to spot abusive tactics like these. Inappropriate use of bonuses damages players’ reputations and gets them in trouble with the casino, which takes strong measures to protect its business and honest players.

How to Avoid Being Labelled as a Bonus Abuser

Here are 10 guidelines to avoid being labelled a bonus abuser and ensure fair play:

1. Pay attention to terms and conditions: Carefully review the terms and conditions of the casino before claiming any bonuses. Recognise the game limitations, wagering requirements, and additional bonus rules.
2. Register Only One Account: Each person may only have one account per casino. Abuse frequently takes the form of opening multiple accounts to claim the same bonus.
3. Follow Standard Betting Patterns: Stay away from repeatedly putting small-risk or safe bets in order to satisfy wagering requirements. Casinos frequently search for trends that don’t correspond to normal gameplay.
4. Avoid Sequential Bonus Claims: Don’t continually switch between bonuses. Play and deposit in between making bonus claims.
5. Stick to Eligible Games: Make sure you only play games that are eligible for the bonus. Playing restricted games can void your bonus and winnings.
6. Provide Accurate Information: Always use your real personal information when registering and claiming bonuses.
7. Stick to Eligible Games: Play only the games that qualify for the bonus. Restricted gaming can make your bonus and winnings null and void.
8. Give True Information: When signing up and making bonus claims, always provide your true personal information.
9. Respect Betting Limits: When using bonus money, comply with any maximum bet limits that the casino may have set.
10. Follow Withdrawal Limits: Be aware of any maximum cashout restrictions linked to bonuses.

By following these guidelines, you can take advantage of casino bonuses without the risk of being accused of abusing them, guaranteeing a fun and fair gaming experience.

Can Casino Bonuses Encourage Problematic Gambling?

Casino bonuses may encourage problematic gambling behaviours in some people. These bonuses frequently have wagering requirements attached, which could encourage players to play longer and place more bets in an effort to fulfil the requirements to cash out their winnings. This might cause you to gamble longer than you had planned. Players who view bonuses as “free money” may take more chances, which could result in large losses and the possibility of trying to chase those losses to “break even.”

Bonuses have the potential to give players a false sense of security or raise their chances of winning, which could lead them to gamble beyond what they can afford. Certain bonuses—such as loyalty programmes or reload bonuses—are designed to keep players interested for a longer period, which may promote continuous or increased gambling.

It’s important to keep in mind that different people have different gambling habits, and many of them use casino bonuses responsibly. They see gambling as a way to spend time without getting into bad habits. The secret to avoiding problem gambling is to play responsibly, within one’s limits, and make use of the many casinos’ available responsible gambling tools, which include deposit and loss limits, as well as self-exclusion tools. These resources are crucial for assisting players in keeping their gambling habits in check.

Is Taking Advantage of an Online Casino Bonus Worth It?

Every online casino bonus you come across seems to be bigger and better than the last. In this highly competitive industry, casinos are constantly re-thinking and re-inventing themselves to lure new players to their website whilst keeping existing players loyal.

In this section, we are going to go over the various types of online casino bonuses available and whether taking them up is worth your time and effort. Plenty of casino players can’t fully comprehend the cost of casino bonuses and often end up frustrated with online casinos, when really there is no industry malpractice in place when it comes to casino bonus offers.

It is always vital to keep in mind that whatever casino bonus is on offer, be it a normal welcome deposit bonus, free play or free spins, as a player you always want to convert your bonus money into real money.

In order to be able to cash out any bonus, you will first have to meet the wagering requirements attached to your bonus, which ultimately dictates the bonus plus the deposit to be wagered a number of times. All of this is mentioned in the terms and conditions.

Understanding The Cost of a Casino Bonus

When conjuring the cost of the bonus, there are a number of factors to take into consideration to understand the cost of the bonus. These include:

• The wagering requirement
• The wagering percentage that a specific game contributes towards fulfilling the wagering requirements
• The house edge

The Wagering Requirement And Wagering Percentage

The wagering requirement is the number of times a bonus or deposit plus bonus, needs to be wagered before the bonus can be withdrawn. Wagering requirements tend to vary from one bonus to another and similarly between one casino and another. The majority of wagering requirements are 35 times the bonus plus deposit, but there have been cases where some bonuses carry a lower or a higher than normal wagering requirement.

When it comes to the wagering percentage, it dictates the percentage a specific casino game contributes towards the wagering requirement. For example, table games such as online blackjack and online roulette contribute a lower percentage than online slots towards a wagering requirement.

Understanding The House Edge

The house edge is the percentage of the total bets that the online casino expects to retain over a period of time. This means that if a casino game has a 5% house edge, the casino is making a profit of 5% from the game over a period of time.

Some casino games have a lower house edge than others, such as online blackjack, while others have a higher house edge with bad odds.

The house edge for a specific game will affect the time you need to play this game before you can expect to make a profit.

Key Facts of Online Casino Bonuses

One of the most important decisions you make when it comes to casino bonuses will lead to either walking away from the casino session with a profit or a loss. This isn’t about how much you want to bet or whether you should be betting on red or black in roulette. This important choice is one that most players give very little thought but is of crucial importance.

• Deposit bonuses: Bonuses are used to encourage new players to join the casino with terms and conditions.
• Terms and conditions vary: Bonuses can vary between one and the other. Even if they state the same amount, such as a ‘100% match bonus’, you need to take into consideration the wagering requirements. If the wagering requirement of one bonus offer is significantly higher than the other, you might want to reconsider your option.
• Bonus offers tie to your real money deposit: If you made a deposit of £100 with a 100% match bonus, your balance would be £200 in total. Even if you have to wager this amount and win, the casino will not let you make a withdrawal until the wagering requirement of the bonus has been met.

So Should You Take up That Bonus?

It depends on a number of factors, namely:

• Which casino games are you playing
• The house edge of those casino games
• The wagering requirement

So, imagine you have come across a casino bonus of 100% with a low wagering requirement of 10x and no game restrictions. This is an excellent offer and one you could meet, so let’s say, you make a deposit of £250. With a 10x wagering requirement, you would need to bet a total of £2,500 before you can make a withdrawal.

If you play a low house edge game such as online blackjack, it would be incredibly easy to meet this requirement and also make a profit.

If your main goal is to make risk-free profits, going after casino bonuses can still give extra value. With more bonus money to play for, you increase your overall chance of winning. With plenty of online casinos to choose from, there is a lot of value for you to take advantage of.

It is of vital importance though that you understand which casino bonuses offer the best value. The biggest bonus does not mean that it’s the best, and some bonuses with a lower value give you the best possible opportunity of meeting the requirements.

With a bit of luck on your side, you can easily come out ahead. With the benefit of extra bonus money to play, this is a more likely scenario. Even if you end up losing, you have still got more time to play and a bigger chance of winning.

✅ We spend 24 hours on average to review each bonus in detail

We are more than just a casino review platform. Our dedicated team of reviewers also focuses on finding the best bonuses, reviewing and testing them to determine whether the terms accurately represent the offer.

Our review process includes up to 16 hours of data collection and 8 hours of research per review, and much of that time goes into reviewing bonus terms and conditions. We provide insider information on the bonus prize, expiry time, wagering requirements, bet limits, and everything else that comes with a casino bonus, so whenever you are looking for a great offer, use our website to learn more.

✅ We reveal exclusive offers

JohnSlots is not a newbie in the casino game. We’ve been a part of the iGaming market for more than 11 years, so many casinos know about us and our review process. We have 12 experts each reviewing up to 15 online casinos a month, meaning they scroll through endless bonuses and know how to spot a good offer from a mile away.

You can trust us to tell you about the promos you’re better off without and those you should hurry to take advantage of!
