Key Points to Consider When Taking an Online Casino Bonus:

  • Every online operator will have a casino bonus of sorts – look into the details of each one
  • There are different types of casino bonus available. We look into these below
  • Look at bonuses that offer you the best opportunities for your budget and your aims
  • Terms and conditions of the bonus are not always perfectly clear – read the small print, read the significant terms and make sure it meets your expectations
  • Nearly every bonus will have some kind of wagering requirements to meet before funds are withdrawable
  • Is the bonus the only feature of interest? Not all online casinos offer the same slots, payment methods or product features.

What is an Online Casino Bonus?

In the UK, there are a plethora of online casinos to choose from. Interestingly, to stay competitive, they offer great and lucrative bonuses for new and existing players. In order to stand out from their competitors, they look to offer the customer the ‘biggest and best' promotions in the form of a casino bonus.

There are plenty of different reasons to choose a particular online casino. These range from the casino games on offer, to the games software they use, and the payment methods available. However, it tends to be the casino bonus that really becomes the deal-breaker.

Are Online Casino Bonuses a Con?

It's a fair question and we must answer that they aren't a con. However, they aren't always easy to navigate through the many terms and conditions.

It's obvious that they're looking to entice you to play but this doesn't mean that they're tricking you with it. There are still plenty of benefits of playing with bonus funds compared to your own. If nothing else, being able to test the casino operator and it's games.

There's been a bit of a shift-change in the UK casino market. Importantly, the UKGC, who regulate and licence online casinos have taken a big stance on bonus terms and conditions, and want all online casinos to ensure that these are transparent and easy to understand.

So whilst we can't say that online casino bonuses have got better, they are certainly more accessible and better thought out. There are also plenty of them which can sometimes make it hard to cut through the noise.

To help you with this, here's a great overview of the different bonus types.

Overview of Casino Bonus Types

As we say, there are plenty of different types of casino bonus to chose from. In fact, new ones appear regularly and tend to spread through the casino world like wildfire. Firstly, it's worth saying that there are bonuses for different types or ‘stages' of player. These are:

  1. Welcome Bonuses
  2. Existing Customer Bonuses
  3. ‘Reactivation' Bonuses

We take a look at what each of these means below and then break down which each of the different types of casino bonus looks like. These online casino bonuses include:

  1. Matched Deposit Bonus
  2. No Deposit Bonus
  3. Bonus Spins or Free Spins
  4. Buy-in and Get Bonus
  5. Cashback Bonuses
  6. Reload Bonuses
  7. Exclusive Casino Bonus

The Online Casino Welcome Bonus

Simply, this is a casino bonus promotion that you're offered as a new customer, to join a particular casino. As we mentioned previously, these may look enticing but there can be some pretty significant terms and conditions attached to them so you need to be wary.

A welcome bonus could be one of many different styles of bonus which we talk you through further below. These can range from Matched Deposit Bonuses to No Deposit Bonuses, to Free Spins and ‘Buy-in and Get' Bonuses.

Existing Customer Bonuses

Once you've joined a new casino and you've played for a while, you'll be considered an ‘active' or existing customer. You may find that the ‘attractive' offers you received to join, may not feel quite as attractive when you look at the follow-up promotions.

That said, any online casino worth its salt in the UK market will have plenty of offers available to retain you as a player. Essentially, they'll look to treat you like a real customer and stop you from playing at competitor casinos. Again, these bonuses could be Reload Bonuses, Matched Deposit Bonuses, or Bonus Spins.

Reactivation Bonuses

Slightly different to casino Welcome Bonuses and Existing Customer Bonuses are Reactivation Bonuses. What does this mean? Well, if you join a casino, play for a while and then stop playing for a significant amount of time, the online casino will treat you as a ‘lapsed' or inactive player.

By reactivating you as a player it can often be much more cost-effective to them from a business perspective than it is to constantly bring new players in. This may sound cynical but it's actually a great thing as it means they offer you another decent casino bonus opportunity – almost as if you're a new player all over again.

Read on to find out more about the different styles of casino bonus.

Online Casino Matched Deposit Bonuses

A matched deposit bonus is the bread and butter of the online casino promotions tab. The most common of bonuses that can be applied as a welcome bonus or an existing customer bonus.

The premise is simple – an online casino will match whatever you put into the casino in your own cash, with bonus cash – albeit with their parameters applied. The matched level could be at any percentage level, with the most common being the 100% matched deposit bonus.

There are often multi-tiered matched deposit bonuses that could see you get a larger bonus funds amount but matched over multiple deposits. So matched at 100% up to £100 across your first four deposits, totaling £400 in bonus funds.

The No Deposit Bonus – A Rare Casino Bonus

The no deposit bonus is, very simply, a bonus that you do not have to make a deposit for. It is mostly offered in small sums, as you can imagine, with the casinos not wanting to give their livelihoods away. Often, a no deposit bonus could be in the form of free spins. So by registering with a casino, it could be enough to get a number of free spins, with no deposit necessary.

With this casino bonus, you can immediately play for real money in the online casino. However, this is by far the rarest of bonuses as the UK Gambling Commission crackdown on promotional terms.

Bonus Spins or Free Spins

The best way to consider this casino bonus is that it's a great way to test out the user journey of a casino and test out a casino game or two.

The premise is again simple, where an online casino will offer you some spins on a specific game or games so that you can try out their product. Sometimes this will require a deposit and other times it may just be a registration that's required.

You may get one set of spins, or you could get multiple lots of spins offered over the course of the week. However, one thing is for sure, any winnings will be subject to terms and conditions, in particular, wagering requirements and game restrictions.

Online Casino Buy-in Bonuses

Slightly different to other casino bonuses, the Buy-in Bonus is more relatable to a ‘bet and get' bonus in sports betting. In that, you actually have to bet in order to get the bonus, rather than just depositing. This bonus can sometimes be a bit friendlier with the wagering requirement terms as you are committing to playing from the offset as a player.

Cashback Bonuses – Rewarding Player Loyalty

The Cashback Casino Bonus is a reward for loyal players who play at the online casino. Depending on the casino, a percentage of the lost bet in the form of a bonus is returned to the player on a weekly, monthly or yearly basis. Most of these percentages are very low. However, this bonus is rarely tied to sales conditions.

Casino Reload Bonuses

These are more tied to the reactivation bonuses we talked you through earlier. You may get a Reload Bonus when you've got no more funds in your account. It won't be a welcome bonus and you'll either be an active or lapsed player with the casino to receive this option. It is designed to bring you back to the playing through offering a generous casino bonus.

The Exclusive Casino Bonus

You're not going to get these too regularly but every now and again you may be offered a casino bonus which is exclusive to you, based on your playing preferences.

It's also worth checking Casino Deal regularly in case we've secured any exclusive bonuses that you can take advantage of.

Bonus Terms and Conditions – What You Need to Know

We couldn't be clearer about this – an online casino bonus doesn't generally come easily, or for free. That's not to say there aren't benefits to them or that you can't win necessarily, but there are terms and conditions that every single online casino will apply.

Every casino bonus is different but it will be mostly the wording that changes, with the idea behind the terms staying pretty standard.

Why do online casinos have such tough terms? Mainly it's to stop the abuse of bonuses – if there were no terms attached, players would come, take the bonuses and then never play again. By adding these terms, it adds a layer of commitment in.

Some significant terms you'll find are:

  • Wagering requirements – How many times you'll have to turnover either the bonus funds or your deposit AND the bonus fund before it's released as withdrawable cash
  • Time limits – You may only get a number of days or months to complete the wagering requirements
  • Payment method restrictions – You may not qualify for bonuses if you deposit via certain payment methods
  • Minimum Deposits – If you deposit less than the minimum, you may not qualify for the bonus
  • Max Bets – When turning over your bonus funds

Thankfully, all of our reviews cover the significant terms and conditions so that you can make a really well-informed decision.

Online Casino Bonus Wagering Requirements

Wagering requirements are the one thing that could frustrate you more about a casino bonus than any other. It's essentially the number of times you need to wager or turn over, your bonus funds or your deposit AND bonus funds, in order to release any winnings as withdrawable cash funds.

As a brief example, you may be asked to turn over a £100 bonus 30x. This means to release the bonus and any winnings as cash, you would need to turn over £3,000 in the casino.

And to make it a bit more interesting, not every game you play contributes in the same way.

Casino Bonus – Game Contribution Percentages

Again, every casino is different when it comes to game contributions. Some casinos keep it simple, fair and transparent, whilst others make it a bit more complex.

Online slots usually contribute up to 100%. However, games like Video Poker or Blackjack, Roulette or Keno often vary massively in their contributions. This could be anywhere from 0% to 100%.

What are the Benefits of Accepting an Online Casino Bonus?

So, we've established that it's not always easy to release any winnings into withdrawable cash funds, however, all is not lost. There are still positive reasons to accept an online casino bonus.

Firstly, as a new player, you get to play and test different casino games, using bonus funds. This allows you to understand what type of games you enjoy and where you may see yourself playing down the line with your own money.

On top of this, another big benefit is that you may actually win and then go on to meet the terms and conditions and wagering requirements. It's a tough ask, but it is a possibility at least.

Do I have to Accept and Use a Casino Bonus?

One misconception that new casino players have is that they have to accept a casino bonus. This just isn't the case.

In fact, many online casino bonuses will require you to opt-in. If you don't then you won't receive it. It's also worth noting that for welcome bonuses, there is often a check box agreeing to accept the bonus, or asking to be removed from the bonus. It requires you to read carefully, but you don't have to taken on a bonus if you don't think it's for you.

Best Casino Bonus FAQs

A Casino Bonuses has many benefits but also come laden with various terms and conditions. They can be a great way to practice different casino slots, and, of course, there's the chance you may do well with the bonus funds. However, if you don't want to be spending your time trying to turn over the wagering requirements then maybe a smaller or more effective bonus is a better option.
A matched deposit bonus is unlocked when a player makes a deposit. The casino will match the deposit in question with bonus funds at a pre-stated percentage. The most common is the 100% matched deposit bonus.
Wagering requirements are the number of times you need to turn over a particular part of the bonus in order to release it (and any winnings) as withdrawable cash funds. This will be the bonus funds or the bonus funds AND the initial deposit generally. The amount of times it's needed to be wagered could be anywhere between 6x and 100x so it's really worth checking the small print.
