Playing casino with bonuses is a great way to quench the gambling urge: You'll get more action for your money, creating more chances of landing that huge and life-changing win.

We're delighted to tell you everything you've ever wanted to know about casino bonuses!

How to find the greatest casino bonus?

In order to find the greatest casino bonus for players, you need to do some digging and comparisons. As almost every casino out there offers bonuses for players, it is important to take a more in-depth look at the bonus amount and bonus terms and wagering requirements. By comparing bonuses, you will find the ones with the lowest wagering and simplest bonus terms.

Though it would be alluring to only stare at the available bonus amount and free spins, you should never let the cover of the book fool you. After all, having fair bonus terms and wagering requirements is essential if you want to be able to withdraw some of your winnings, too.

A great casino bonus for players is both generous and fair. You might be able to grab some bonus money and free spins on your first deposit or even the first two or three deposits. The minimum deposit for claiming the casino bonus is low, and wagering requirements realistic and fair. Also, in the best-case scenario, you will not need to spend hours reading the long bonus terms because they are simple, clear, and to the point.

Usually, we refer to both welcome bonuses and other available bonuses when talking about a casino bonus. Welcome bonuses are available along with your first deposit(s), while other casino bonuses (such as reload bonuses) are claimable after you have used your welcome bonus.

Casino bonuses can include, for instance, free spins, bonus money, or cashback bonuses. The greatest casino bonus depends on what kind of bonuses you like. Some players prefer free spins, some bonus money, and some wagering free cashback options. Remember that you can always join more than one online casino and claim available casino bonuses for yourself.

The Most Important Considerations When Choosing a Bonus

There are a few things worth considering before jumping in headfirst and grabbing a casino bonus. Everyone who likes bonuses will naturally try to find the biggest bonus available, but only the experienced will think twice and consider the other variables. A great bonus isn’t just big, but it’s also favourable for the player. Here are 6 things to consider about casino bonuses:

  • How big is the bonus - How many percent bonus money can I get up to what maximum amount?
  • Wagering requirements - Do I have to wager the bonus money only (B), or does it state that I have to wager both the bonus and my own deposit (D+B)?
  • Eligible games - What games can I play while the bonus is active, and how much do they contribute towards the wagering?
  • Max and/or Min bets - What are the limitations to betting, what are the maximum and minimum limits?
  • Time limitations - How many days do I have to meet the wagering requirements?
  • Deposit and withdrawal methods and limitations - Am I entitled to the bonus if I make a deposit with X-method (consider VISA casinos, Skrill casinos, Bitcoin casinos)? Are there any withdrawal limitations after I’ve met the wagering requirements (daily, weekly, monthly)? There are several variations to the applied limitations, which is why it’s so important to understand bonus the T’s & C’s.

We monitor and evaluate the market closely to be able to find and list all the amazing casino bonuses. In our lists, you'll find the latest tax-free casinos with thorough reviews and the bonuses detailed. It's a good idea to take advantage of the greatest casino bonuses on offer and get to know the newcomers on the gaming market.

Add your own filters to the above list to be sure you find the most suitable bonus for you.

Biggest Bonuses for Online Casinos in 2021

The biggest casino bonuses aren't necessarily the greatest bonuses, so we’re separating the two. Some of the biggest bonuses we’ve seen recently offer 500% bonus money up to a few hundred euros along with a few hundred free spins on the side. Now, the T’s & C’s weren’t great, so all in all, the bonus in the above example is only decent when looking at all the parameters.

It's wise to consider more aspects of a bonus than the bonus money.

Casino Deposit Bonus

What is a deposit bonus? A deposit bonus is a general term - make a deposit into your casino account and get a bonus. It's not difficult to grasp the concept, but there are usually some T's & C's, making it a bit more tricky. These bonuses provide anything from 20% to several hundred percent bonus money. If you are interested in taking advantage of this offer you can find the best deposit bonus casino here.

Cash Match Bonus

The essence of a casino match bonus is that it matches the amount of your deposit. The bonus doubles your bankroll, and this creates more chances of winning big. The amount of the boost is stated in the bonus, i.e. a 100% bonus up to €100 or whatever sum. Because of the boost they give, match bonuses are sometimes used as welcome offers at certain casino sites. All you need to do is browse through our list of online casinos. Apply your own filters to find the casino match bonus that best fits you.

Cashback Bonus

The cashback bonus promotion

The cashback bonus promotion is usually set within a set time-frame. Most casinos do it weekly, but some offer a cashback bonus daily and even monthly. Also, the casino determines the percentage of the cashback, i.e. the money returned to the player. While the promotion lasts, the player's losses are calculated. Based on the determined percentage, a sum of money is returned to the player's account.

Casino Reload Bonus

A casino reload bonus is a bonus that gives something back to the player. This is why it's a common bonus that casino sites use for rewarding their loyal customers. However, the reload bonus is for all players to enjoy and not just for old players.

How to collect a Casino Bonus

It's not always clear how to claim a casino bonus. Some casinos require a Code while some casinos require a maximum deposit. This is how to do it at this casino:

A casino will usually offer several types of bonuses. Even the very active players will usually have something extra to add to their bankroll. If you're very active, you will do wisely in reading our casino reviews. It'll tell you details about recurring bonuses and competitions, the latter which commonly provides specific bonuses for the purpose of competing against other players. These competitions also include prizes ranging from cash prizes to exotic travels.

Casinos conduct campaigns like "Monday Madness," "Friday Free Spins," and so on. Many casinos offer Loyalty Bonuses - the more you play, the higher status you'll receive, along with better and more bonuses.

100 Deposit Bonus

The 100% casino bonus is one of the most common bonuses offered by casinos. But how does it work exactly?

Well, a 100% casino deposit bonus is exactly what it sounds like – it's a bonus that doubles your deposit. The way it works is that after you have claimed the 100 deposit bonus, you will receive your bonus money in a separate balance from your real money balance. However, this doesn't mean that you cannot win real money with your bonus money. It just means that you will have to wager your bonus money a certain number of times before you can cash it out.

Because the 100% deposit bonus is such a coveted offer, online casinos have created different variations of the bonus to stand out. This offer's most common variations are the 100% casino welcome bonus and the bonus deposit 100 sportsbook offer.

200 Casino Bonus

What if we told you that tripling your deposit is possible at many casinos? Would you think that we are nuts? Well, the fact of the matter is that a growing number of casinos are indeed offering 200% casino bonuses.

The 200% casino bonus is a match bonus that can be given to both new and existing customers. With this bonus, a casino will triple your deposit amount. So, if you deposit 20€, then you'll get 40€ in bonus money, giving you 60€ cash in total to play with!

Because the 200% casino bonus is such a coveted offer, online casinos have created different 200 casino bonus types to win new customers over. These bonuses include the 200 deposit bonus and 200 welcome bonus offers. However, in general, 200% welcome bonuses are only granted to new players that can meet the bonus's terms & conditions. But if you are an old customer, you may be eligible to receive a standard 200% deposit bonus.

300 Deposit Bonus

The 300 deposit bonus is one of the best match bonuses offered by online casinos. But how does it work?

While you can claim 300 deposit bonus offers at some casinos, the bonus can actually mean one of two things. You will either get up to 300€ in extra bonus funds or triple your deposit amount.

For example, if you claim the bonus and deposit 100€, you may get 300€ on top of your deposit or 400 euros in total. So, in this case, a 300 deposit bonus would give you four times your deposit amount. Alternatively, a 300% deposit bonus could mean that the casino will just triple your deposit. So, in this case, if you deposit 10 euros, you would get 30€ on your casino balance.

Remember always to read your bonus's terms & conditions to understand how it works!

400 Casino Bonus

It's safe to say that the online casino 400 deposit bonus is one of the best deals that casinos offer. But how does it work?

The 400 casino bonus is exactly what it sounds like – it's a bonus that quadruples your deposit. With this offer, you can play your favourite casino games and slots for that much longer and get a better chance to hit the jackpot!

500 Casino Bonus

We would forgive you for thinking that 5xing your deposit is impossible. I mean, why would a casino give so much money for free?

Well, there's a good reason why casinos want to reward new players. By handing out a generous bonus like the 500 casino bonus, players become that much more loyal towards the casino. However, it should be noted that these bonuses come with very high wagering requirements, which means that only the luckiest players can reap the rewards of these bonuses.

Special Bonuses

If you'd like to learn more about different types of casino bonuses, we have listed some special bonuses below for you to look into. Level up your gambling experience by claiming the greatest bonuses offered by top online casinos!

Welcome Bonuses


The casino welcome bonus is the most treasured of all casino bonuses, mainly due to the enormous sums of extra money offered by some casinos. It's usually the biggest bonus available at any casino.

When you make your first deposit at a casino where you've never played before, you'll also receive a bonus to welcome you as their new customer. This is also called a first deposit bonus (duh!) and is the one offer that's common for 99.9% of online casinos. The welcome bonus should not be confused with a no deposit bonus; these are two different types of bonuses.

A very common welcome bonus offer gives 100% bonus money, up to a certain sum, on top of your own deposit. An example is a "100% bonus up to €2000". This means "deposit €2000 to get a €2000 bonus, and a total of €4000 to play for".

In case we deposit more than the above-mentioned €2000, we'd still not receive more bonus money than the capped sum.

Free Casino Bonuses

Many players' favourite bonus! It's also called a "no deposit bonus" or a free casino bonus without deposit. It's one of the most revered and sought-after casino bonuses. To be able to get a bonus without making a deposit of our own is simply brilliant. It allows us to try out the casino before fully committing by depositing some of our own money.

However, to get a bonus without making a deposit doesn't mean that you can withdraw the bonus money and simply leave the casino. The whole idea is for the new customer to get a feel for the casino. You'll receive a small sum of money or a fist-full of free spins to play around the casino.

In the likely case, you should win something while playing with the bonus; you'd better be aware of the T's & C's to avoid frustration on your side. Remember that winnings from a free bonus are tied to wagering requirements.

The casino bonus you receive when you sign up is typically around $5 to $10 and will be added directly to your account upon joining the online casino. For free play money and free rounds without a deposit, you should check out our latest offerings!

Mobile Deposit Bonus

If you happen to play casinos on your phone a lot and would like to find the best available bonuses for mobile casinos, then you're in luck! There's no difference in the available bonuses just because you play on your phone or tablet. All bonuses offered by an online casino are available and up for grabs on mobile devices too. Nowadays, around 60% of all online traffic comes from mobile devices. That's a staggering number, and online casinos are aware of this fact, and hence they have adjusted accordingly.

Whether you're playing casino on your phone, tablet, or PC/Mac/Linux computer, you have full access to all bonus types. Simply choose what type of casino bonus you want, go to the relevant page, and apply your preferred filters.

Live Casino Bonus

Live casino bonuses might also be available at online casinos, and these often include either bonus money or a risk-free bet. Note that sometimes you can use your regular casino bonus in live casino games. The best live casino bonus, though, is the one meant only for live casinos.

Bonus Without Wagering Requirement

There’s a unicorn bonus in the industry. Imagine a casino bonus without wagering requirements. They exist! But, just because there’s no wagering required doesn’t mean it’s completely freed of T’s & C’s. Read more on our dedicated page.

Get bonus with Code

Some casinos choose to apply specific codes to their bonuses. All it means is that you have to enter a code to be eligible for the bonus. It's very straightforward, and if in doubt, we've included step-by-step instructions in our dedicated Bonus codes -page.

Non Sticky Bonuses

The pro-player bonus that's more beneficial for the player than it is for the casino. It has to do with the T's & C's. If you're not yet familiar with these bonuses, we urge you to visit our page about the topic. Shortly put, you can cancel the bonus at any time when you play with the non sticky bonus.

10 Deposit Bonus

The idea that you can make a small deposit to play with much more money may sound too good to be true. But a growing number of online casinos offer big bonuses for small deposits. These fantastic offers can be claimed as free spins, cashback bonuses, and even as massive prize draw entries. If you are interested in playing with this offer, you can grab your preferred 10 deposit bonus on this page.

Sportsbook Bonus

The sportsbook bonus is a popular bonus among sports betting fans. The bonus comes in many forms, but the no deposit bonus sportsbook is widely considered to be the best sportsbook sign up bonus. You can learn more about the offer on our page dedicated to the bonus.

Exclusive Casino Bonus

What is an exclusive bonus? Put shortly, exclusive bonuses are offers that casinos give exclusively to a certain group of players. At Mr Gamble, we have managed to negotiate some amazing deals for our readers that they cannot find anywhere else. If you want to delve deeper into these offers, you can find all Mr Gamble's exclusive bonuses here.

Cashable Casino Bonus

As you can guess from the name, a cashable casino bonus is an offer you can cash out. Unlike a sticky bonus, a cashable casino bonus is redeemable. This means that you can withdraw any winnings you have made with your bonus once you have fulfilled the wagering requirements. The bonus can be very lucrative if you manage to land a big win playing slots or casino games.

Casino Bonus Terms & Conditions

casino bonus wagering and max bet explained

Whenever you redeem a casino bonus, the terms and conditions specify the bonus's wagering requirements, the time limit to meet the requirement, maximum and minimum bet value, and eligible games. This means that you must complete the bonus wagering requirement within a specified time in order to withdraw your winnings.

You should always read the terms and conditions of the bonus carefully!
