What Are Slot Bonuses?

What Are Slot Bonuses?If you’ve ever played at an online casino before you’ve likely come across the array of different offers and promotions that sites advertise. These can range from an initial introductory offer to bonuses tailored towards certain casino games. Of course, the best UK casinos attempt to please as many customers as possible and because so many players enjoy online slots there are bonuses that are specifically geared towards these games.

Essentially, online slots bonuses enable you to try out a range of new games via free spins or with a boosted bankroll. They can even provide a risk-free chance of winning real money if you choose the right offer. After claiming your bonus, you’ll get to enjoy all that each online slot has to offer along with the chance to experience the assortment of lucrative features available. What’s even more exciting is that many of these slot bonuses allow you to play the latest NetEnt releases.

So, if, like us, you prefer to play the most innovative games that the industry has to offer we’ve got plenty of slot promotions that allow you to do so. Grab yours today and to become the next big Starburst winner or you could even strike Aztec gold when playing Gonzo’s Quest – the choice is yours!


Finding The Best Casino Slot Bonuses In The UK 2020

The hunt for specific casino bonuses can be an arduous task. You can end up spending hours scanning different sites and online casinos for the offer you’re looking for. That’s why we set our slot bonus hunters the task of compiling a list of the best offers that are currently available and they certainly didn’t come up empty. So, instead of spending your precious time searching hundreds of different sites you can find the latest slot bonuses all in one convenient location – right here at NetEntCasino!

Throughout this page, you’ll find a wide range of different offers including many which are absolutely free. All you need to do is select your preferred bonus and follow the step-by-step guide below to be in with a chance of landing that huge win.

 

How To Claim Your Online Slots Bonus

  • Step 1: Take a look at the assorted slot bonuses on this page and decide which is the right one for you. Click the advertised offer to head directly to the online casino where you can claim your bonus.
  • Step 2: If you’re not already an existing customer you’ll need to sign up for a new account. Do so by locating the registration button and follow the on-screen instructions to complete the process.
  • Step 3: If your bonus requires a promo code locate the section where it must be used – this is sometimes required during the registration process but it may also be found within your chosen site’s promotions page.
  • Step 4: Some offers may require a deposit. If necessary, head to the casino’s cashier/banking page to add funds to your account.
  • Step 5: Your online slots bonus should now have been credited to your account. Load up any of the eligible games to use either your free spins or bonus funds.
  • Step 6: Sit back, relax and watch the reels spin. Hopefully, you land a huge win, meaning you could perhaps request a real money withdrawal!

Types Of Slot Bonuses

As we previously mentioned, slot bonuses come in all sorts of different shapes and sizes. They can provide a number of free spins for you to use on certain games or they can come in the form of cash bonuses that allow you even greater choice. Additionally, some are entirely free of charge whilst others require a deposit to activate. Below, you’ll find an overview of the most popular slot bonuses in the UK.

 

Welcome Bonuses

A welcome bonus is an online casino’s primary offer available to new customers. After signing up for a new account you’ll be eligible to receive these promotions when making your very first deposit. In nearly every case it involves some sort of deposit match but it can also include additional offers such as free spins, along with extra bonuses on subsequent deposits. Bear in mind that when claiming a welcome bonus there are certain terms and conditions that apply. These may affect your ability to withdraw any winnings until you meet the attached wagering requirements.

 

Free Spins

Free Spins are the bread and butter of the typical online slot enthusiast. A lot of the time this type of bonus comes in conjunction with an initial welcome offer but there are also certain bonuses to be had when new games are released. Free spins allow you to play certain online slots for free by awarding a set number of spins at a specific stake. Any wins you then gain from these spins are credited to your online casino account balance. However, more often than not, this is in the form of bonus funds. Before you’re able to request a withdrawal you’ll need to convert the funds into real money by meeting specific wagering requirements – i.e. wagering your total bonus balance a certain number of times.

 

Deposit Bonuses

Deposit bonuses are what may become available after using the online casino welcome offer. These are a great way to get extra funds to play with as they come in the form of a deposit match – whatever you deposit, the casino will match with a set percentage up to a maximum amount. The biggest offers are usually reserved for new customers and VIPs but the best slot sites in the UK do tend to provide recurring bonuses to loyal slot players too. As you may expect, these do come with certain terms and conditions and they also have wagering requirements attached. However, on the whole, they’re typically great value.

 

No Deposit Bonuses

A no deposit bonus is something that’s credited to your account without the need to make a deposit. Where available, these are usually awarded to customers after creating a new account and can come in the form of a free cash bonus or no deposit free spins. Regular players can also benefit from this generous type of bonus. Sites will often award promotional offers via email or as part of a loyalty programme to customers who have played at a site for some time. Also, just because these offers are entirely free it doesn’t mean you can’t win real money. In fact, it’s one of the best ways to potentially do so at a UK online casino!


The Importance Of Bonus Terms And Conditions

Just because online casino bonuses are designed to appear attractive, don’t assume that there aren’t any strings attached. Although the best UK slot bonuses are usually great value for money, you should always read the fine print before claiming your offer to get a clearer picture of what’s available. The terms and conditions can mean the difference between turning your bonus into a real money withdrawal or losing out entirely. So, we suggest you carefully pore over the T&Cs to discover information regarding the following details:

 

  • What the bonus wagering requirements are.
  • If a minimum deposit is required to trigger the offer.
  • The maximum amount of funds the online casino will match.
  • Whether or not your winnings are capped to a certain amount.
  • For how long your bonus is active before it becomes forfeit.
  • Which games you are eligible to play with free spins.
  • The value of your free spins.
  • The maximum amount you can wager per bet when using a cash bonus.

How First Deposit Bonuses Work At UK Casinos

How First Deposit Bonuses Work At UK CasinosFirst deposit bonuses, usually known as welcome offers, are usually awarded as some sort of deposit match. You may have seen an online casino offering something along the lines of 100% up to £200 on your first deposit, but what exactly does that mean?

Well, however much you deposit, up to a maximum of £200, the casino will match. So, if your first deposit at the site were to be £200, you would also receive an additional £200 to play with – £400 in total. Still, you can deposit less and still receive a 100% match but anything of greater value would not qualify for the offer.

However, you must bear in mind that the extra money will likely be credited as bonus funds and as such is subject to certain terms and conditions. The most significant of these are the wagering requirements attached to your bonus as this dictates how many times you must wager your bonus funds before the site converts what remains into real money and becomes eligible for withdrawal.

Using the hypothetical deposit bonus above as an example, let’s apply a 35x wagering requirement, which is often the standard. Say the wagering requirement only applies to your bonus funds, this means that you would need to wager your £200 bonus 35 times before it is converted to real money.

 

£200 (bonus funds) x 35 (wagering requirement) = £7,000 (sum of wagering)

 

Now, let’s apply the same formula to a deposit bonus that requires you to wager both your deposit and bonus.

 

£200 (deposit) + £200 (bonus funds) x 35 (wagering requirement) = £14,000 (sum of wagering)

 

As you can see, even though the online casino is offering a 100% bonus it isn’t going to be easy to get to the point where you can request a withdrawal. The value of the wagering requirement plays a huge part in the process and the lower it is, the better. So, we really must underline the point that you should read the terms and conditions before opting into any deposit bonus. It may seem like an easy way to get free cash to play with but the terms and conditions can, at times, be extremely restrictive.


Most Popular Online Slots With Bonuses

Not all online slots are created equal. There are releases that have captured the imagination of players for many years now and also those that are played once and quickly forgotten about. Thankfully, the majority of the best game provider’s creations manage to stand the test of time and one developer’s games in particular often rise above the rest – NetEnt.

As NetEnt slots have become so popular, you’ll find their games included in many slot promotions. So whenever you choose to test out a new site using a no deposit bonus or get the chance to try out some new games you’ll have the opportunity to play any number of the following games:
