Casino Bonus 2021

What stands out with a casino bonus 2021? Just as it has been for the last couple of years, the big competition between different casinos pushes them to offer players even more. Many players are tired of the really high wagering requirements. Therefore, there are more casino bonuses in 2021 that have a little bit lower wagering requirements. And perhaps more importantly, these requirements, terms and conditions need to be transparent so you know what applies to you.

Another thing that stands out if we are looking at a UK online casino bonus in 2021 is the variety of those. We are very used to classic deposit bonuses and spins. Now, they will come in many different shapes. Something that we strongly believe is well-needed to attract players.

How to get the best casino bonus 2021?

As we often mention, new casinos 2021 are, in general, handing out the most attractive offers. Even though there are new players every year, they need to get their cut of the already existing players. And why change brand if you don’t get anything extra for it? This is why you always should take a good look at what the new brands offer and how to get the most out of it.

More trends we see in UK casinos 2021:

  • A larger variety of slots to choose from for your spins bonuses
  • Deposit bonuses for choosing certain payment options
  • Bitcoin bonus and bonuses for other types of cryptocurrencies
  • Free tournaments to participate in

Different types of Online Casino Bonuses

Even though many brands apply the same kind of promotional offers for its players, we do see some that really stands out. Sometimes, you might be able to get up to a 500% deposit bonus for example. You can also, and will for most of the time, find lower percentages like; 100% casino bonus or online casino bonuses 300%.

Almost all of which comes with high wagering requirements and other terms and conditions. Something we always recommend you to read more about at the specific casino. We will now go through some of the different bonuses, such as no deposit and deposit offers, so you know what to look for once it is time to get started.


Welcome Bonuses

A welcome bonus is often considered the most beneficial casino bonus. This means that you as a new player (18+), get a bonus for just becoming a member at the casino in question and make your first deposit(s). A casino welcome offer can look very different depending on which casino you choose to start playing. One common thing is that you get a number of free spins, sometimes even without deposit requirements. That said, without having to deposit any money, you have the opportunity to play some of the online casino slot machines for example. This is an incredibly good option for getting to know what you like (and don’t like) about an online casino in the UK. As always with any type of bonus, read the terms and conditions so that you know any limitations about the offer.

casino welcome bonus 2021

No Deposit Bonus

Depending on in which country you play, more or less often, we see no deposit bonuses for new players. This means that, just by creating an account, you will be able to play, have fun and with luck also win a little bit. Most common are no deposit free spins. However, some brands really stand out by giving a new player some money to play with. The sweet deal about this is that it gives you the possibility to play at mostly whatever game you want, whilst free spins most often are dedicated to one or a few slot machines.

Even though you don’t need to make a deposit, beware of the terms and conditions. Most of the times you need to turn over your winnings a couple of times to be able to withdraw the money. There might also be maximum winnings with such bonus money, as well as other terms.

no deposit casino bonus 2021

Free Casino Bonuses

So, whilst many bonuses are seen as “free”, not many are. Even the no deposit bonus, mentioned above, isn’t really for free. Of course, you do get some spins or extra money, sometimes without any deposit. But almost always you need to wager your winning before able to withdraw them. That is why the really free casino bonuses aren’t that common. But, sometimes they do exist.

What we at Casino Viking consider to be a free casino bonus is when it is without both deposit and wagering requirements. This gives you the possibility to withdraw your winnings straight away (except maybe a minimum withdrawal limit, usually around 10 pounds). It comes without saying, if you encounter a brand with this offer – go for it. Even so, there are always requirements so always read the full terms and conditions before using any kind of bonus.

Additional Casino Bonuses

Once you make the first deposit; you usually get a very nice offer –  like doubling or maybe even tripling your deposit. Many casinos also give you additional free spins for you to use on one or many video slots. Some casinos also offer you the opportunity to choose a welcome bonus from a list. You can get many different packages if you want a high bonus on your deposit. Maybe you are more interested in getting plenty of spins. In order for you as a player to be able to get a customized package that addresses your way of playing at the casino.

In conclusion, we can say that a welcome bonus is one of the most advantageous and great casino bonuses you can enjoy.

Finding the best casino bonus offers in the UK

It’s really hard for people to make up their minds about anything where there are many choices. It’s confusing, and we don’t care much for the confusion. Well, this is the exact case with the online casinos. There are hundreds upon hundreds of these casinos that operate online, and new ones are being created even as we speak. So, which casino should you choose? Again – it can be very difficult for you to find the best one among all of the competitors.

Which is why we have decided to create a list of the online casinos that offer the most interesting casino bonus. When you think about it, the online casinos are practically very similar to one another. At least in the sense of the games that you can play and the overall atmosphere. The sole thing that changes consistently from one casino website to another is the “skin”. You will get to see new images and hear new sounds and music. But the core of the experience will mostly be the same.

What else to think about?

Let’s be honest. The promotions a website is offering are a big deal when we choose a place to play at. But, it really isn’t everything. How it looks, the user-friendliness, game selection and payment options are just some of the other important things. However, due to the wide variety of UK casino sites today, you should be able to get it all. So just scroll up this page to see the best casino bonus 2021 in the UK or go to our review page to get a full list of all the casinos.

Casino Bonuses are one of the best ways to attract and retain customers. I think it is important that the players know that the online casino wants to make money.

But, at the same time, it is hard to see a better benefit for the players than a generous casino bonus.
