Best Online Casino Bonuses in May 2024

As a player, I like to make sure that the online casino I sign up for offers a range of bonuses that will make my gameplay journey one to remember. In my 4 years of working in the industry, and many more playing slots before that, I’ve claimed enough bonuses to break down everything you need to know:

• Reading the terms and conditions carefully will help you understand if the requirements to fulfil your eligibility for the offer are realistic for your usual playing style.

• Going for the right offer will help you enhance your time at your favourite online casino.

• Take your time and make sure you’re playing responsibly, but keep in mind that most bonuses expire.

When I compared all the best online casinos we list on CasinoTopsOnline, I found Happy Slots to have the best casino offer. This is because Happy Slots offers new players not only a fantastic first deposit bonus at the casino but also additional offers for the long run.

How I Rank the Best Casino Bonuses

Since my expertise mainly revolves around identifying the best casino bonuses available, I’m here to give you some insider tips on how we identify and rank the best casino offers and the operators that stand out as the best for their promotions. Here are 5 criteria we run through:

• Not only do I check the bonus amount, but I also consider the overall value of the bonus.

• I find that the usual range of wagering requirements will be between 30x and 45x. Anything above 45x is considered too high and I wouldn't recommend you go for such an offer.

• Typically the welcome offer will have a valid period of 7 days and the free spins are usually valid for 24 hours.

• Making sure the casino has a stellar reputation and their licence is solid.

• Reading through other players' feedback and their reviews of how they found their experience claiming a bonus on online forums.

I’m usually able to find all the information I need to determine if a specific bonus suits me best either in the general casino terms or the individual bonus T&Cs.

Different players have different gameplay styles, which also means they'll require different types of bonuses. Here are our favourite bonus categories matched with the best online casino sites listed by myself alongside our expert team:

• Best Cashback Bonus by Happy Slots

• Best Free Spins Offer by Verde Casino

• Best Welcome Bonus by Rooli

• Best Reload Bonuses by Casimba

The Best Cashback Bonus Offered at Happy Slots Casino

With my deposit of €20, I claimed Happy Slots' fantastic casino welcome offer, from which I got €40 bonus funds in return. I could play any game in the casino library to fulfil my wagering requirements, so I took my old faithful Sweet Bonanza for a spin. This casino is the only operator offering a cashback offer as part of their welcome package from our top 10 best operators offering casino bonuses. And this is extra to the original matched deposit bonus they offer.

Pros:

• The cashback offer does not have any wagering requirements

• You can withdraw up to a maximum of €2,000 from the daily cashback offer.

• Fantastic well-rounded range of promotions for returning players as well.

Cons:

• Wagering requirements for the matched offer are high at 30x

• To claim the cashback offer you need to deposit daily between 06:00 - 05:59 CET

Why Did I Choose Red Dice for the Best Cashback Bonus?

The fact that you can get up to a hefty amount back on your losses per day without any wagering requirements is what pushed this cashback bonus to the top, standing out on top!

My Favourite Free Spins Pick is Included in Verde Casino's Welcome Bonus

I can always count on finding a decent free spins offer available on the Verde Casino promotions page. This time, it’s part of their online casino sign-up bonus and I got 220 free spins out of it! I first deposited €10 and was granted 50 free spins which I could use on Big Bass Bonanza. On my second deposit of €20, since the minimum requirement here was €15, I got another batch of 50 free spins which I had to use on Endorphina’s Joker Stoker. Finally another two deposits of €10 and €15, I was awarded a total of 120 free spins, 50 on Starburst and the rest claimed on my final deposit which I could play on Book of Fallen. What I enjoyed most about this is that within the same welcome offer, I got to experience 4 different slot titles.

Pros:

• Hefty free spins bundle as part of the welcome offer.

• Multiple free spin offers are available to both new and returning players.

• Range of games you can claim the offer on.

Cons:

• The offers can not be combined with others.

• High wagering requirements up to 30x.

Why Did I Choose Verde Casino as the Best Free Spins Offer?

The total amount of free spins you can get in this bonus surpasses many online casinos' free spins offerings, with returning players also offered a great number of free spins as part of various other bonuses bringing the total amount in free spins to a truly impressive level.

The Overall Best Welcome Bonus I Tried and Loved Is Rooli Casino's

The heftiest casino welcome bonus I’ve claimed this month is definitely Rooli Casino’s. The maximum any player can get from their current offer is a whopping €4,000, and they’re claimable over the first 4 deposits meaning you’re not expected to deposit a lump sum at one go. If the matched deposit is not exactly what you’re looking for, you also have the chance to get up to 475 free spins in total.

Pros:

• Wide variety of games available to wager on.

• Good selection of deposit bonuses and VIP perks for returning players.

• Great selection of banking options you can use to deposit into your account.

Cons:

• The website and its bonuses can be difficult to navigate.

• The bonus comes with relatively high wagering and deposit requirements.

Why Did I Choose Rooli Casino for the Best Welcome Bonus?

I was just impressed at how much you can get back as a player overall, making this bonus the best in how much it contributes to new players’ experience at Rooli.

No One Does Reload Bonuses Like Casimba

If what you're looking for is a casino that offers multiple fantastic reload bonuses, Casimba Casino roars loudest, offering the following variety reload bonuses:

Slotshammer Reload Bonuses	Reload Offers
Monday Boost	40% Reload Bonus up to €500 claimed on all deposits every Monday.
Wednesday Bonanza	Choose between three offers on Big Bass Splash open every Wednesday; 50 Free Spins when you deposit between €30 and €39.75. Free Spins when you deposit between €40 and €49, or 100. Free Spins when you deposit €50 or more.
Friday Frenzy	Choose from these three bonus options for Legacy of Dead every Friday; 50% Match Bonus up to €50 + 25 Spins when you deposit between €20 and €49. 60% Match Bonus up to €100 + 50 Spins when you deposit between €50 and €99. 75% Match Bonus up to €200 + 75 Spins when you deposit €100 or more.

These offers were enough to convince me that Casimba is the best overall casino for reload bonuses, offering a wide and versatile range for all kinds of players including casino players, live dealer game players and sports bettors.

Pros:

• 7 different reload promotions are available 3 times a week.

• Versatile options frequency.

• Wide range of banking options to withdraw any winnings from bonuses.

Cons:

• Not offered as frequently.

• Applicable to only a select few games.

Why Did I Choose Casimba for the Best Reload Bonus?

The reload bonuses were deemed most attractive at Casimba for the versatility they provide with three options open to players twice a week. The deposit requirements for these bonuses are also quite reasonable making them more accessible than many other bonus offers.

Are Vulkan Vegas' VIP Bonus Offers The Best?

Yes! A top-quality experience in many ways, VulkanVegas stands out for many reasons, not least its live-dealer games and no-deposit bonuses, however, it gets on our list here for its top-of-class VIP programme.

This programme offers 99 levels and 10 statuses, awarding a point to a player for every €10 wagered, which can eventually be exchanged for real money or contribute to both a reload and cashback bonus.

Pros:

• Great variety of payment methods.

• Great VIP programme with phenomenal bonuses and cashback up for grabs.

• Excellent welcome bonus.

Cons:

• The casino is restricted in some countries.

• Slow withdrawal times.

Why Did I Choose VulkanVegas for the Best VIP Bonuses?

The VIP at VulkanVegas stands out because of the strength of the rewards offered in both reload bonuses and cashback, increasing your chances of gaining some extra cash as well as allowing players to play longer on the same deposit amounts.

What Different Types of Online Casino Sign Up Bonus Are Available?

At the best online casinos, you can expect to get anything from a deposit bonus matching a percentage of the amount on your deposit, a number of free spins, or even a cashback offer on a portion of your lost bets when you sign up. 

What Is a Welcome Bonus?

A welcome bonus, usually in the shape of a package, is a promotion any player can claim when they register to an online casino as a new member. Casinos design these offers competitively to give players a fun start to their journey in the games library. Welcome bonus offers normally include free spins, matched deposits, or even a combination of both. I’ve also encountered the following additions to some top casino operator’s welcome offers:

• Additional cashback casino bonus offers usually at 10% cashback

• No-deposit requirements on the offer

• Some even offer prizes, like a ticket for a chance to win a jackpot or even a trip to watch your favourite match.

Let me break down some of the most important details and some of my tips from my own experience with the best casino welcome bonus types:

• If you can aim for a bundle rather than a single offer, you can end up getting more

• Don’t be fooled by big numbers! A matched offer of 100% up to €100 might look nice, but a matched offer of 100% up to €50 + 200 Free Spins will work out to be more fruitful if you love slots!

• I always like to check out other casino bonus offers I can get in the long run as a player, not just the welcome offer itself! Sometimes the new player promotion might seem chunky, but then the casino might not offer you decent offers after you’ve signed up!

How Can Players Activate a Casino Welcome Bonus?

These are the six simple steps I followed to activate my welcome offer at Happy Slots:

1. I selected Happy Slots because I made sure it was a reputable online casino.

2. You should then check the casino promotions page to make sure the welcome package is what suits you best.

3. I always advise my players to read and analyse the T&Cs carefully.

4. If you’re happy with this offer, hit the registration button. I normally find this towards to top right corner of the page or in the menu, ofcourse every site is built differently.

5. You’ll need to give some of your personal details. I filled in some personal information including my date of birth and my e-mail address. I also submitted some of the documents I was asked for, just so that when I come to withdraw any funds later on, the process will go quicker.

6. Normally for welcome offers a deposit is needed, make sure you meet the minimum deposit requirement if this is the case. If the entire package is a no-deposit offer then you can move to the next step.

7. All you need to do now is play some games and have fun! You need to make sure that you’re playing qualifying games for you to be able to claim your bonus.

8. If you're successful, you can withdraw your bonus winnings from your account or use them to continue playing.

What Casino Promotions Do You Usually Find at an Online Casino

Besides the welcome offer, once you’re registered at your favourite site, you may look at their promotions page to see all the casino bonus offers you can claim as a player.

At the best online casinos, you should always find a decent amount of promotions on this page. Here’s a taste of what you can expect to find at the casinos we list:

What Do Loyal Players Get?

VIP status is given to a player who shows loyalty towards the casino. When I earned my VIP status at Happy Slots I was offered some extra special rewards, and I noticed that I also had higher bonuses available now. You can even be rewarded with a trip to Las Vegas for your consistent playing, birthday presents, and a dedicated account manager who speaks your preferred language when available.

Many VIP memberships come in different levels, usually indicated by a Bronze, Silver, Gold and Platinum membership. Each level comes with exclusive perks for regular casino game players. Some key tips and highlights to consider:

• VIP Casino Bonuses boost the loyalty of players;

• They can be very generous with benefits;

• Like any other casino bonus, take your time to check the terms and conditions.

How Can You Choose the Best Casino Bonus?

• Compare different bonuses - Take your time to evaluate the different types of casino bonuses available to ensure that you're making the right choice! If you're limited with time you can check out user review platforms or read reviews from casino experts like CasinoTopsOnline.

• Read the terms and conditions - Before moving forward in claiming an online casino bonus take a good look at the terms and conditions. Two key things to look out for are minimum deposit limits and any expiration dates or time limits you get to claim the bonus!

• Check for wagering requirements - the playthrough requirements need to be fulfilled so you can ensure that claiming the bonus remains affordable to you. These can range from as little as 1x to as much as 150x.

• Claim more bonuses - As long as the terms are favourable to you, there is a higher chance of getting greater gameplay. Keep in mind that not all casino sites will allow you to claim multiple bonuses at one go.

What Casino Bonus Terms and Conditions Did I Look Out For?

The most common casino bonus terms and conditions include wagering requirements, maximum winnings, game restrictions, and time limits. These terms are put in place to ensure that players and the casino have a fair and safe gaming experience. By understanding these terms and conditions, players can avoid potential issues and enjoy a safe and enjoyable online gaming experience.

Here are the most common casino T&Cs that I’ve found at the best online casinos:

• Wagering requirements

• Maximum winnings

• Game restrictions

• Time limits

• Deposit limits

• Country restrictions

• Age restriction

• Verification requirements

• Using bonuses simultaneously

• Payment method restrictions

How Do I Fulfill Casino Bonus Wagering Requirements?

Wagering requirements refer to the amount of money required to bet before being able to convert your bonus cash into real money. Typically it will range between 20x to 50x of the casino bonus amount and initial deposit. It is important to check the terms and conditions and see whether your deposit is included in the wagering requirement, as this will make a significant difference. 

For example: You deposit €100 and receive a €100 bonus cash giving you a €200 bankroll. If the wagering requirement is 20x the deposit plus bonus, you would need to bet €4000 before being able to withdraw your winnings.
