Also, read any terms and condition of the casino and bonuses before you play.
Different types of Casino Bonuses 2021
To make it as easy as possible to take advantage of all casino bonuses 2021 offered, we at CasinoOnline.casino wants to dedicate this page for just that. When you sign up as a new player in a casino, you will get welcome bonuses. This type of casino bonus is usually the best. At the top of the page, you can see the different bonus categories. These offers are only valid for new players.
It is also worth mentioning that a player that has played for a long time will also obtain different versions of VIP offers as a casino bonus at casinos online. A casino bonus that you get from VIP clubs may be a deposit bonus if you want to make a new deposit to keep on playing. It is also quite common to receive free spins as you make a deposit.
Almost every gambling site has a dedicated page on their website to give you information about the current bonus and its terms and conditions. After signing up you can also often go to “Your Page” or similar, and see what unique promotions and offers that you can possibly get. Sometimes you need to contact the support in order to receive the casino bonus but most often you will get it immediately after depositing and using a welcome bonus.
Welcome Bonus at a Casino Online
A welcome is often the most advantageous casino bonus in 2021. Depending on which casino you decide to play on, a welcome bonus may seem very different from time to time. One of the most common and popular casino bonus is getting a number of spins immediately after registration. You have the opportunity to play some of the online casino gaming machines such as slots and have the chance to win as well. These bonuses without a deposit are not super common but they are there. The more common welcome bonuses are given to players that make their first deposit(s).
To try a no deposit welcome bonus is a very good option in order to learn a bit about a new casino and its ease of use, gaming, and so on. All casinos that we work with have a very high level in general, and they almost always offer fun and solid welcome bonuses 2021.
Once you make your first deposit, you usually get a very good bonus, such as doubling or even tripling your deposit along with a number of additional free spins. Some casinos offer you to choose between different kinds of welcome bonuses (see above). They have different packages if you are primarily interested in getting a high matching-bonus on your deposit or are more interested in a lot of free spins. The player will then be able to get a tailored package that appeals to your way of playing at the online casino. It all boils down to that the welcome bonus is one of the absolutely most advantageous casino bonuses that you can take part of.
What to be aware of
A casino bonus can come with low or no wagering requirements but most of the time you will have to wager the casino bonus before you can make a withdrawal. This is most players aware of but here are a few more things that can be good to know before you sign up at a casino.
All in all, it is worth checking the bonus terms and conditions in order to not be disappointed at a later stage. We try our best to be fully transparent and only list the best but you will need to read and understand the specific casinos’ terms to fully understand the details for the bonus.
Deposit bonuses and matching bonuses
A deposit bonus or a “matching bonus” means that casinos give you extra money on your deposit. If you for example deposit €/$/£ 50 with a matching bonus of 200%, it will get you €/$/£ 100 in bonus, which means you will have a total of €/$/£ 150 to play for. When depositing €/$/£ 50 and having a 100% bonus you get €/$/£ 50 bonus so you will have €/$/£ 100 to play with. If you are lucky you can even get a 300% or 400% casino bonus. In that case, you get a 300% offer and deposit €/$/£ 50 you will have as much as €/$/£ 200 to play with.
| Deposit Money (€/$/£) | % | Bonus Money (€/$/£) | Play With (€/$/£) |
| 100 | 100 | 100 | 200 |
| 100 | 150 | 150 | 250 |
| 100 | 200 | 200 | 300 |
| 100 | 300 | 300 | 400 |
| 100 | 400 | 400 | 500 |
| 100 | 500 | 500 | 600 |
The matching bonus is very common and popular offer among casinos. On top of that, you often get free spins, loyalty points or similar. Of course, every bonus has terms and limitations for you that you need to check out before in order to not be disappointed if you win a lot very fast. There are wagerings that need to be done and other things most of the time.
VIP and Loyalty Programs
VIP clubs in online casinos start to become very common and nowadays players can take part in a variety of exciting promotions, bonuses, free spins, loyalty points and much more. The higher the level you reach, the better deals you will be able to take part of.
Loyalty programs, or “reward systems” as one might call it, means that loyal players who play a lot also will be rewarded in the form of various bonuses. You can be rewarded by getting a lot of points while you play and climb to different VIP levels where you get gifts. Both VIP and Loyalty programs are being developed at a rapid pace and aim to make the gaming experience more fun. If you like to play a lot on the same casino you can often exchange your points for either bonuses or even trips and products.
Casino Bonus Codes 2021
At our site, you normally do not need to use a code when you sign up. You will get the bonus immediately after signup or after depositing. If you need a code it will say so in the specific terms and conditions of that casino and its bonus, so always read it. During big holidays like Christmas, it is pretty common that you can get extra good deals on codes. So make sure to visit us on a regular basis to always get the best casino bonus 2021.
However, bonus codes mean that you type in a word, most commonly a combination of letters and numbers, in connection with that you take advantage of an offer and thus get extra money or free spins for example. You can get bonus codes in many different ways, and these are awarded to both new players and players who are already customers of a casino.
Cashback
In 2021 Cashback has become increasingly popular. Cashback means that players get back a part of the money they might have lost during a cold streak. To give an easy example; if you have a cashback of 20% and lose €/$/£ 100 to the casino, you could get €/$/£ 20 back. Normally the cashback is between 5% and 20% but this can, of course, vary even more as well as the terms of this cashback bonus. This is sort of an insurance policy or a discounted gaming one could say. It is a nice way to get some money back even if this is not super common at the time of writing.
Mobile Casino Bonus 2021
In 2021 it is pretty common to get better offers if you sign up for your mobile and play on a mobile casino. One of the main reasons is that many casinos want to show the new platform and interface that they have worked hard to provide you. Some have even created really beautiful apps that aim to make the gaming experience more quick and fun. Another reason is that game developers have created amazing mobile games that they want to show the world. You can, for example, get a better offer when trying such games. The game developer is, of course, earning money when you choose to play a game that they have developed so it is in their own best interest. Some of the best developers of mobile games 2021 are NetEnt, Microgaming and BetSoft. The slots are getting much better with amazing graphics and sounds effects. The biggest difference for 2021 is that Live Casino is getting so much better on mobile devices. So be on the lookout for special mobile bonuses that you might find on some very mobile-focused online casinos.
