Best Online Casino Bonuses in 2025

There are thousands of online casinos scoping the internet world on a quest to grab your attention and keep it. One of the ways they separate themselves from the competition is through offering the best online casino bonuses to not only get players to sign up but also to keep them playing regularly.

To make the most of your casino experience, you need a fair grasp of how these bonuses work. 

On this page, we break down everything that matters, including the types of casino bonuses, criteria to narrow down the best ones, and the steps to claim them.

What Are Online Casino Bonuses?

Online casino bonuses are the incentives that online casinos use to entice new players to sign up and keep existing players regularly engaged with the platform. They take several forms, including bonus funds and free spins, which are added to a player's account for extra value and extended playtime. They usually come with wagering requirements, either on the actual funds you receive or the winnings from them.

Types of Casino Bonuses 

There is a wide range of casino bonuses to cater to different players. Here are the ones that commonly feature at most online casinos.

Welcome Bonuses

Like the name suggests, welcome bonuses target new players who have just created an account with a casino. They often come in the form of matching your first, or up to four, initial deposits.

For example, a casino may offer a 100% deposit match bonus up to €500, doubling your initial deposit. Then, the casino may offer a 50% deposit match bonus for your next three deposits.

No-Deposit Bonuses

While no deposit bonuses are rare, they offer risk-averse players a way to experience different casino games without spending a dime. However, whether they are bonus funds or free spins, they often come in small amounts.

Free Spins

Player preference for online slots drove the adoption of free spins. Players receive a set number of spins for specific online slots for a shot at winning real money without spending their own.

Casinos may offer free spins to existing players and/or incorporate them into the welcome bonus for a bigger punch of rewards.

Reload Bonuses

Reload bonuses are offered by casinos to their existing players. Just like welcome bonuses, they typically come in the form of deposit matches once you’ve used up your welcome bonus.

While they come in smaller percentage matches than the welcome bonus, they still add value for players. 

Minimum Deposit Bonuses

Minimum deposit casino bonuses are ideal for players with smaller bankrolls, as the bonuses can be claimed with a deposit as low as €5 or €10. This allows the casino to be more inclusive of all players regardless of their bankroll.

Non-Sticky Bonuses

The best non-sticky casino bonuses are known for keeping two sets of funds separate: the bonus funds and the deposit amount. The casino often starts by drawing from the deposit amount, allowing players to withdraw any winnings before touching the bonus funds.

Cashback Offers

Cashback Casino bonuses allows players to recuperate a percentage, usually 5-15%, of their losses over a specific period, which softens the blow of losing streaks.

VIP/Loyalty Rewards

VIP rewards are the prime real estate of online casinos, where players receive exclusive perks as they progress to higher levels. Examples of these perks include customised bonuses, increased withdrawal limits, and access to a personal account manager.

How to Evaluate Casino Bonuses

Here we’ll explain some key factors players should scrutinise at online casinos to ensure they get the most value out of bonuses.

Wagering Requirements

Wagering requirements prescribe how many times you’ll need to bet the bonus amount before initiating a withdrawal. This means that lower wagering requirements are ideal.

When scouring through online casinos, you’ll often come across wagering requirements as low as 20x to 30x.

However, the wagering requirements may apply to only bonus funds or both bonus funds and deposit. The casino reviews on our website highlight whether the wagering requirements apply for only the bonus amount, or both the bonus and deposit.

The difference between the two is significant.

A 30x wagering requirement for a bonus amount of €100 means you’d need to wager €3000 before you can withdraw the bonus and any associated winnings.

Alternatively, a 30x bonus + deposit wagering requirement for a bonus amount of €100 and a deposit of €200 would mean you need to wager €9000 before initiating a withdrawal of the bonus and any associated winnings.

Expiry Dates

The expiration dates refer to the time limits within which you can use the bonus. They vary in length, with some offering a month and others a few days before the bonus becomes inaccessible.

It is in your best interest to cross-check the expiry date to understand whether you can realistically fulfil the requirements in the prescribed time.

The most common expiry dates range from 24 hours to 30 days.

Game Restrictions

Not all games contribute to the wagering requirements, and others that do only contribute up to a specific percentage. The best choice are often slots, which usually contribute 100%.

Occasionally, there are bonuses that are restricted to specific games entirely; for instance, some online casinos only allow free spins for Big Bass slots.

Maximum Win Caps

In most cases, bonuses will have a cap on how much you can win using them. There are several types of win caps, including fixed amount caps, multiplier-based caps, and percentage-based caps.

A fixed-amount cap of €100 would mean that even if a player wins €300 from a bonus, they can only withdraw €100.

Bonus Percentage

This applies to the percentage match on deposit bonuses, typically between 100-300%.

A higher number doesn’t necessarily mean it’s better, as casinos offering very high percentage matches usually have stringent terms for the bonus.

Step-by-Step Guide to Claiming Casino Bonuses

Once you’ve identified a casino bonus using the criteria above, it's time to claim it. Here are the simple steps to follow:

✔️ Step 1: Choose a Reputable Casino

The most important thing to check is that the casino has a licence. Reputable casinos carry licences from regulatory organisations like the Malta Gaming Authority and the United Kingdom Gambling Commission.

✔️ Step 2: Register and Verify Your Account

Follow the steps to create an account, including sharing your email and address and agreeing to the terms and conditions of the casino. Once you’ve completed the registration process, you may need to verify your account by clicking a link often sent to your email or inserting a code sent to your mobile number.

✔️ Step 3: Enter Bonus Codes (If Required)

Some casinos or affiliate casino sites provide a bonus code that you may insert during the registration process or once you’ve registered.

✔️ Step 4: Meet Minimum Deposits

You’ll need to meet the minimum deposit for deposit match bonuses. These often range from €10 to €20.

Popular Games for Online Casino Bonuses

Online casinos will specify which games fulfil the bonus wagering requirements, including at what percentage. Here are the popular options.

Slots

Most players will wager their bonus funds on slots as they contribute 100% towards the wagering requirement, with the exception of some high-RTP and low volatility slots like Blood Suckers. This can differ between casinos, make sure to check the terms and conditions - some slots may be excluded altogether and contribute zero to bonus fund wagering.

You can browse our library of thousands of demo slots and try them for free.

Table Games

Table games include RNG variants of roulette, blackjack, and baccarat, which contribute lower percentages to the wagering requirement. Their contribution typically ranges from 10 to 20%.

Blackjack is a player favourite, well-known for its simple strategies and low house edge.

Casino Bonuses and Payment methods

The most accommodating online casinos provide a wide range of casino payment methods, including bank cards and e-wallets. The choice of payment method should not affect the accessibility of a bonus, and any exceptions will be stated in the bonus terms for the casino.

Visa and Mastercard

Bank cards are the most popular payment option at online casinos. You will mostly come across Visa Casino sites and Mastercard Casino sites.

E-wallet Payments

E-wallets are known for their fast payment processing for both deposits and withdrawals.

Crypto

Crypto is the new neighbour on the block, gaining slow but steady popularity. The primary benefits of crypto payment methods are their anonymity and security.

There are many crypto currencies available, most famously Bitcoin, Ethereum, and Tether.

Expert Tips to Maximize Bonus Value

It is crucial for players to maximise their bonus value by using tried-and-tested tips from experts.

Here they are:

💡Tip 1: Prioritize Low Wagering Requirements

If you want to make it as easy as possible to turn bonus funds into withdrawable cash, low wagering requirements of 35x or lower are your best friend.

💡Tip 2: Use Bonuses on High RTP Games

Where possible, use funds on online casino games with a high Return to Player percentage, like online slots, to maximise your chances of meeting wagering requirements with funds left over.

💡Tip 3: Track Expiry Dates

Know the expiry dates of your bonus and keep an eye on it, even with a reminder if you have to, so that you don’t lose any unused funds.

Common Pitfalls to Avoid

Here are some of the common pitfalls you should avoid when playing with bonus funds.

❌ Pitfall 1: Ignoring Terms and Conditions

Make sure to read the fine print of the terms and conditions, which dictate withdrawal requirements and how to use the bonus. Breaking a rule can result in the bonus funds and any associated winnings being forfeited.

❌ Pitfall 2: Chasing Unrealistic Offers

If it sounds too good to be true, it probably is. Players should steer clear of bonuses with extremely high match percentages or suspiciously low wagering requirements.

Example: A casino promotes a 300% welcome bonus, but on a closer look it is in fact spread over four deposits, where the first deposit gives a 150% match and the next three deposits gives a 50% match respectively.

❌ Pitfall 3: Overlooking Country Restrictions

Some casino bonuses are only available in specific countries, which makes it vital to ensure yours is one of them before signing up. Country availability for bonuses should be clearly stated, but if you are unsure, contact customer support at the site. Don’t use a VPN to circumvent country restrictions as it’s against the rules and you will most certainly be caught.

Conclusion

Online casino bonuses are part and parcel of both new casino sites and older, well-established brands. Once you have the knowledge to evaluate one bonus from another, and how to avoid common mistakes, you’ll be on your way to maximising your online casino experience. As always, remember to gamble responsibly.
