Best online casino bonuses and offers in April 2025

What is an online casino bonus?

Online casino bonuses are normally part of a special promotion that either attracts new customers or helps regular customers stay loyal by keeping things fresh and exciting. These can be in the form of either deposit matches, free spins, or even loyalty perks, which give players the incentive to return and play again.

Most welcome offers require players to place a deposit, which means that you’ll need to use your own funds to claim. Some casinos may also offer no deposit bonuses, which can be a great opportunity for players to try out new games and even win real money without risking any of their own bankroll. Many casinos also offer personalised and tailored offers for existing players to encourage continued engagement. 

Types of casino bonuses

The best online casino bonuses will have a variety of offers that will cater to a number of different preferences, such as cashback bonuses. Here are some other top ones to look out for:

Welcome bonuses

Welcome bonuses are designed to draw in new players by offering bonus funds or free spins on your first deposit. They’re also an excellent opportunity to explore what games the casino has and to try them out for a small initial deposit. 

Free spins

With free spins, you’re able to test out certain games, which can be an exciting way to try out some thrilling slots action without using any of your own funds. They’re often included in welcome packages or offered as part of ongoing promotions. Free spins are normally associated with certain slot games. This gives online casinos a chance to promote these games and put a spotlight on them.

No deposit bonuses

This can give you bonus funds or free spins without needing to put down a deposit, so they’re perfect for players who want to test out a casino before committing with their own money. These no deposit bonuses are popular with beginners who want to test out a platform first, risk-free! However, they normally come with much stricter terms and conditions, like capped winnings or higher wagering requirements.

Seasonal bonuses

These are normally tied to specific events or special holidays throughout the year, like Halloween or Christmas. This offers unique opportunities for players to claim special bonuses during limited times, which makes them fun and festive as they’re usually themed or associated with exclusive tournaments that tie in with whatever the event or occasion is. For example, a casino might have an advent calendar at Christmas with daily giveaways and prizes.

Reload bonuses

Reload bonuses reward existing players for making further deposits, often in the form of a percentage match on the deposited amount. These bonuses are usually much smaller than welcome bonuses, but they can be claimed more often. You can find them via weekly or monthly promotions, depending on the casino or type of promotion offered.

Loyalty programmes

Loyalty programmes reward players for playing consistently. This could be in the form of collecting points that can be redeemed for bonuses, cash, or perks. Most casinos use tiered systems where you’re able to climb levels, and the higher you climb, the better the rewards, such as faster withdrawals, luxury gifts, or even personalised account managers.

How we rate online casinos and their bonuses

After reviewing countless online casinos, we then take what we have learned and use it in our very own TopsRank system. This is done to ensure that we not only cover the entire casino experience as a whole but also look into the specifics. 

In this case, we’re prioritising bonuses. Since players will often use their bonuses to test out a platform or to give their bankrolls a boost, we make sure to give them the attention they deserve in our ratings. 

Bonuses make up 20% of the total score for each casino that we rate, and this covers things like welcome offers, ongoing promotions, cashback deals, and how fair their terms are.

 We also pay close attention to important factors like:

• Wagering requirements

• Eligible games 

• Expiry times

• Payment methods

But a good bonus deal is only one part of the picture. With our unique TopsRank system, we will also consider the site’s design (15%), payment options (15%), game selection (15%), safety and security (15%), industry partnerships (10%), and the overall user experience (10%). 

All of these help to determine whether an online casino is worth visiting, as the best online casinos will provide players with a safe and secure environment that also provides great value, as well as a fun space to play in.

We also rate casinos on a 10-point scale based on the following categories: Excellent, Very Good, Good, Average, and Not Recommended, which makes it easy for you to compare all of the available options quickly and easily. We’ve done all the hard work for you, so you don’t have to!

How to choose a casino bonus

While this guide recommends some of the best casino bonuses available, it’s also important to consider using the following criteria before choosing the right bonus deal for you for any future offers that might come your way. 

Things like game titles, payment methods and bonus terms are crucial when making your decision. It’s also important to check the casino’s reputation and licensing, as well as the level of customer support that they can offer. 

So while a bonus might seem attractive at first glance, if the site lacks the necessary security and support, it’s not worth the risk. Let’s take a look at some of these factors in more detail:

Read player reviews and forums

Exploring community sites or any dedicated casino forum will give you great insight into the customer experience from real players. Forums also feature useful advice regarding the casinos that have great customer service, fair dispute resolutions, and those that pay out quickly. Reading about other players' experiences can help you avoid possible mistakes and help you make more informed decisions when choosing a casino bonus.

Check for a bonus code

Some bonuses might require a special promo code, so it’s always best to check if a code is needed upon registration or with a deposit. These are usually clearly posted on the promotion page, but sometimes they might arrive by email or in pop-ups after signing up with your chosen site. Also, watch out for expiration dates, as some may have a time limit and can expire after some time.

Find bonus amount and the minimum deposit

Consider this: bigger bonuses are not always better! A bonus that requires a lower deposit and has fairer terms can be more rewarding in the long run. For example, a 200% deposit bonus on €20 is much easier to attain than 100% on €1,000. And as always, check that the minimum deposit is reasonable and if it fits your budget. 

Ineligible payment methods

Some payment methods, particularly e-wallets like Skrill or Neteller, aren’t usually eligible for welcome bonuses. Before using your preferred depositing method, check and familiarise yourself with the terms and conditions first, as some casinos might have limits on specific payment types as a way to reduce bonus abuse or fraud. 

Wagering requirements

This is normally the most important factor of all. Bonuses with 20x to 30x wagering are considered fair. Anything more than 40x starts to feel less appealing. Some online casinos advertise bonuses with lower wagering requirements, but this sometimes limits the eligible games on offer. So always read the full terms before deciding to claim any bonus deals.

Excluded games

Bonus funds and free spins can sometimes have restrictions on where they can be used. Slots typically contribute 100% toward wagering requirements, while table games may contribute less (for example, 10%) or not at all. Certain games, such as jackpot slots, are typically excluded. Other bonus terms can also limit use to high-RTP slots only or make them unavailable on certain live dealer games. 

Bonus expiry

Time limits matter, as some offers will have expiry dates of about 3 to 7 days. So this time window might not be suitable for casual players. Failure to meet the criteria in the given time frame could lead to losing these extra funds or free spins on offer. 

How to activate an online casino bonus

Activating a bonus is normally straightforward, but the process can sometimes vary between casino operators. Here’s a simple step-by-step guide on how to activate a typical online casino bonus:

1. Choose a casino from our recommended list and sign up for an account.

2. Read through the terms and conditions carefully.

3. Select the bonus and enter a bonus code (if required) during registration or when depositing.

4. Make your first deposit using an eligible payment method.

5. Start playing eligible games that count toward the promotion.

6. Meet the wagering requirements laid out in the T&Cs.

7. Once the playthrough restrictions have been met, you can withdraw your winnings!

How to fulfil wagering requirements

If you hope to convert your bonus into real, withdrawable cash, you need to understand wagering requirements. Every casino bonus is attached to terms that will specify how many times the bonus (or deposit + bonus) must be wagered before a withdrawal can be made. 

Opting for low wagering bonuses can make this process much easier and increase your chances of cashing out your winnings.

How wagering works

For example, if you claim a €100 deposit bonus with a 30x wagering requirement, you’ll need to wager:

€100 (bonus) x 30 = €3,000

This means that you have to bet €3,000 before any bonus-related winnings can be withdrawn. Assuming the playthrough restrictions apply both to the deposit and bonus, then the playthrough restrictions would look like this:

(€100 + €100) x 30 = €6,000

You will have to complete the wagering in a specific period of time (7–30 days usually), and you need to remember that not all games will contribute equally to meeting these requirements.

Games that count

Different casino games will account for a certain percentage towards the wagering requirements.

• Slots usually contribute 100%.

• Table games like blackjack or roulette may only count for 10–20%.

• Live dealer games often contribute 0% (unless specified).

• Some slots may be excluded entirely, especially jackpot games or high-RTP titles.

Tips to fulfil wagering requirements

Keep the following tips in mind for the best chance of turning bonus funds into real cash:

• Stick to slots or games that contribute 100% toward wagering requirements.

• Watch out for time limits — complete wagering requirements before the bonus expires.

• Choose low volatility games, as they provide smaller and more frequent wins.

• Look out for bet limits, as some casinos cap max bets during play (e.g., €5 per spin).

• Track your progress: Most sites will show you how much wagering remains.

Responsible gambling

Casino bonuses should enhance your gaming experience, and not encourage problematic play. This is why it’s crucial to make sure that you use your bonuses responsibly so that you can avoid common issues that may arise. Here are some tips on responsible gambling practices to keep in mind:

• Understand all terms and conditions before accepting a bonus. 

• Only play with what you can afford to lose — always treat bonuses as fun extras.

• Avoid chasing losses: If you lose your bonus, it’s not worth depositing again just to try and win it back.

• Take breaks regularly to avoid compulsive play. Most reputable casinos will have tools in place to remind you when you’ve been playing for a certain amount of time.

• Don’t overspend chasing higher-tier rewards or loyalty perks — remember that loyalty points and VIP perks shouldn’t push you beyond your set budget.

Avoid bonus abuse

So, what’s bonus abuse? This is when players use casino promotions against what they’re intended for. Examples include: opening multiple accounts, purposely playing low-risk bets or using virtual private networks (VPNs) to access region-specific offers. 

Casinos watch for this type of abuse, so they may void winnings or suspend accounts if they see these rules being violated. So it’s always best to follow the rules and only accept the bonuses that you’re eligible for.
