What is an online casino bonus?

For example the most common online casino bonus is:
100% first deposit bonus up to €100, meaning that if you deposit €100 of your own money, the casino will give you another €100 of bonus money. This means you can double your bankroll and basically play longer – thus leading to a better chance of winning as well.

Casino bonuses in a nutshell:

  • Welcome bonuses for new players
  • You get more bang for your buck and lower your own risk
  • Mainly include deposit bonuses or free spins
  • Even no deposit bonuses are possible
  • Strict terms often apply to casino bonuses

What types of casino bonuses are on offer?

These days, casino bonuses come in all types and sizes. Whatever you’re craving for, the best online casino bonuses of 2024 will give your gaming experience a serious boost.

The most popular casino bonuses are of course welcome bonuses offered to new players, but the bonus party doesn’t stop there. If you’re lucky, you can even grab a no deposit bonus of free bonus money meaning that you don’t have to risk a penny of your own cash.

Casinobulister brings you all the best promotions and lists them clearly on one page. Check what’s on offer and claim the bonus that suits you best. Next we will introduce the most common casino bonuses offered today.

The most common casino bonuses offered today

  • Welcome bonus

    New players are always privileged when it comes to the best online casino bonuses. That’s just natural, because casinos want to attract new customers. So basically the biggest bonuses are normally available to those who register a new account and make their first deposit. These offers are called welcome bonuses, and they can be massive!

    Typically a good welcome bonus is a combination of bonus money and free spins as shown in the example below.


    • 100%/€200 bonus + 100 free spins

    The above bonus would mean that you get up to €200 added bonus on your first deposit. So if you deposit €200, you get €200 of bonus money and 100 free spins on top of that.

    The bonus percentage and the amount of bonus money and free spins varies a lot between different casinos. The most common first deposit bonus is 100%/€100.

    Nowadays, the best casino bonuses can be even 200% or more, and the amount of bonus money can reach thousands of euros. Anything is possible, so keep your eyes open for the best deals!

    Note that welcome bonuses can also be divided into several deposits. Some online casinos even offer a welcome package that can be claimed in 3, 4 or even 5 parts.

  • Deposit Bonus

    Online casino deposit bonus is the most common promotion and can be offered to new players and old customers. As stated already, the best deposit bonuses can be claimed on your initial deposit after registering a new account.

    Basically a deposit bonus simply means that you’ll get a certain amount of extra bonus money on top of your own instalment. Typically your deposit is doubled, but in some cases the bonus percentage can be much higher or lower.

    What to consider when comparing deposit bonuses?

    • Bonus %: On average deposit bonuses are 100%, but 200% deposit bonuses are also common. There have even been 500% first deposit bonuses offered.
    • Maximum amount of bonus: Besides the bonus percentage, the amount of bonus money is just as important. For example you might get a 100%/€100 from some casinos but a 100%/€1000 from others.
    • Minimum deposit: All deposit bonuses have a minimum deposit required to claim the bonus. This can be especially important for someone who wants to claim the free spins package for the lowest possible price.

    There are of course plenty of other details to keep in mind, such as wagering requirements and other bonus terms, but we will talk about those later in this article.

  • Free spins

    Who doesn’t love free spins? Besides deposit bonuses, free spins are the most popular and common type of casino bonus. They are offered as welcome bonuses to new players and as part of campaigns and special promotions to old customers.

    New players can often get hundreds of free spins on their first deposit – sometimes even no deposit free spins meaning that you don’t have to use your own money at all.

    When claiming free spins from online casinos, you should of course pay attention to the amount of spins but also the wagering requirements and other possible limitations. Also, keep in mind that free spins can be for a certain slot only.

    Types of free spins:

    • Free spins that are offered on top of your deposit
    • No deposit free spins
    • No wager free spins

    Don’t forget that even though the spins are free, you can still win real money! So check our list for the best free spin offers and claim yours!

  • No deposit bonus

    Definitely the most tempting casino bonuses are the ones that don’t require you to risk your own money at all. A no deposit bonus is just that, meaning you don’t need to make a deposit to claim it.

    Mostly no deposit bonuses come in the form of free spins. Sometimes you can also get purely free money to play with, but in that case the amounts are relatively low.

    Just keep in mind that the best offers usually involve the toughest terms and conditions. So if you’re able to claim an amazing no deposit bonus, you can be pretty sure the wagering requirements aren’t going to be easy. There might also be other sneaky restrictions like capped winnings, which is really unfortunate in the case that you strike a big win.

  • Reload bonus

    Once you’ve claimed and used your welcome bonuses, there might always be more deposit bonuses on offer for existing players. For example, many online casinos offer a reload bonus that is usually smaller than the initial first deposit bonus.

    Reload bonuses can be offered on a weekly basis. For example some casinos offer a weekly 50% reload bonus on a certain day of the week. That motivates players to make a weekly deposit on that day to get some extra playing money on top of their deposit. 

  • Cashback

    As the word suggest, cashback means that you get a certain percentage of your deposit back in case you don’t win. A typical cashback offer is 10% but can sometimes be higher especially for VIP players.

    Many online casinos offer a continuous weekly cashback bonus, which means that you will get a return on your total losses from the past week. If you lost €1000 and the casino offers a 10% cashback, you’ll get €100 back on your gaming account.

  • VIP offers

    Online casinos tend to take good care of their loyal customers, and to do so they offer VIP programs filled with extra benefits. Anyone can join theses loyalty programs from the moment you register a new player account. It’s always advisable, since VIP players are handed the best casino bonuses in the long run!

  • Exclusive bonuses

    Casinobulister is always in the hunt for the best bonus offers out there and wants to offer extra special deals for you. We negotiate exclusive bonuses for our players so that your online gaming experience can be as profitable as possible.

    So don’t forget to check out exclusive offers that are updated regularly!

How to identify the best online casino bonus?

Picking the best casino bonus is easy, as long as you know what you’re looking for and what suits your needs. The biggest bonus might not automatically be the smartest option for you, if your budget doesn’t allow you to get the most out of it.

There are many aspects to consider when choosing casino bonuses. Some things are of course purely about personal preference.

Below we’ve listed a few basic rules to help you out:

Pick a bonus that suits your own budget:
If you can only make a €50 deposit, it’s much smarter to choose a 300%/€50 bonus than a 100%/€1000 bonus.

Try to avoid high wagering requirement and difficult terms:
A tempting casino bonus might not be as good as it looks if the bonus terms are too strict. High wagering requirements and other pitfalls will make withdrawing your winnings difficult.

Always claim no deposit bonuses when possible!
There’s no financial risk involved, but you can still win real money.

Non-sticky bonuses are always more favourable,
because they allow you to withdraw your winnings when playing with your own deposit. Basically, it means that you use your own deposited money first without having to worry about tough bonus terms. If you win while playing with the deposited money, you can discard the bonus and cash out your winnings right away.

New casino bonuses - bigger offers await

If you’re looking for the biggest online casino bonuses, it’s always worth checking the newest casinos. That’s because the newer and less known casinos simply have to promote themselves in order to attract new players.

New casino bonuses are now bigger and better than ever, so you don’t want to miss out on the best deals! Remember to keep an eye on Casinobulister’s updated bonus list and the new online casinos popping up all the time.

Casino bonus wagering requirements

Finally, the overall quality of a casino bonus is determined by the bonus terms. It’s very common that the bigger bonuses have tougher wagering requirements and other unfortunate restrictions. That’s why you have to take all aspects of the bonus into consideration and find the best middle ground.

What other bonus terms should you always check:

  • Validity period
  • Minimum deposit
  • Maximum bet
  • Game restrictions
  • Maximum cashout/winnings cap
  • Payment method restrictions

A very typical wagering requirement for online casino bonuses is 35x bonus, which means that you have to wager a sum that’s 35 times your bonus amount.


If you claim a 100%/€100 bonus and the wagering is 35x this means that you would have to wager €3,500 before you’re allowed to withdraw your winnings.
  • €100 x 35 = €3,500

Note that the WR can also include the deposit part making the requirement twice as difficult:

  • €200 x 35 = €7,000

Always pick a safe casino bonus

No matter how great the bonus offer is, you never want to risk playing at a dodgy casino. However, if you focus on the online casino bonuses shown on this page, your money is sure to be safe. Casinobulister only accepts trusted casinos with a good reputation operating under a secure licence.

If you want to make sure you’re choosing a safe casino bonus, here are a few factors to check:


Reliable licence (such as MGA)


Responsible gaming tools available


Bonus terms must be clear and fair


Other aspects such as payment methods and general terms and conditions must be up to par

5 tips to make the most of your casino bonuses

When playing with bonuses, there are many tricks to make your gaming session more profitable. It doesn’t mean that you’re sure to win more money, but there are some smart tactics to take advantage of.

Obviously, your first mission is to select the best casino bonus for you and after that you can focus on some smaller aspects in terms of using the bonuses.

Here are 5 tips that can give boost to playing with casino bonuses:
Choose the right games – high RTP slots

Take advantage of the lowest wagering requirements when possible


Avoid bonuses with a low winnings cap


Claim many bonuses at the same time – you don’t have to settle for just one


Consider higher bets to chase bigger winnings (according to your budget)
