MAIN TYPES OF CASINO BONUSES

Different types of casino bonuses appeal to different playing styles, so it’s important to have a clear understanding of each before claiming any. Here, we’ll go through the most common incentives and reveal how bonuses work.

FREE SPINS

If you’re into slots, online casinos offering free spins are the way to go. Free spins allow you to spin the reels of selected slot games without any initial deposit or as a reward for making a deposit.
While no deposit free spins require no upfront investment, deposit free spins are unlocked when you fund your account. Therefore, it’s crucial to familiarise yourself with the terms and conditions, including wagering requirements and game restrictions, to optimise your chances of converting those free spins into withdrawable winnings.

DEPOSIT/MATCH BONUSES

Deposit bonuses are bonuses that are awarded when you make a deposit at an online casino. In most cases, the casino will match a percentage of your deposit up to a certain amount.
For example, if you deposit $50 and the casino offers a 100% match deposit bonus up to $100, you’ll receive an extra $50 to play with.

NO DEPOSIT BONUSES

No deposit bonuses are rare, but they are one of the most popular types of bonuses around—and it’s easy to see why. No deposit bonuses are special sign-up rewards that require no initial deposit. They’re available to new players, so all you have to do to claim them is create an account at a new casino.
Some variations of this incentive include no deposit free spins bonuses and free cash no deposit bonuses.

Casino Welcome Bonuses

Welcome bonuses are the usual promotions found in online casinos, designed to reward new players. They come in different forms. For instance, a single offer welcome bonus can be presented as a no deposit bonus upon registration or a match bonus on the first deposit.

In addition, there are welcome packages, which include at least two deals. These packages usually cover the first three deposits and are only redeemable through the first successive deposits.

High Roller Bonuses

High roller bonuses are exclusive incentives created for customers who make substantial initial deposits, frequently exceeding $1,000. These special offers are usually provided as percentage match bonuses or cash gifts.

Moreover, high rollers are granted VIP status, offering a range of privileges and personalised benefits, such as dedicated account managers, special match offers, birthday gifts, and more.

Why Choose a High Roller Bonus?

If your budget allows it, choosing a high roller bonus gives you access to a larger bankroll and more winning potential, exclusive awards and bonuses greater than the usual welcome bonus, and access to the VIP club.

Sticky vs Non-Sticky Bonuses

Sticky bonuses are bonuses that are not withdrawable, meaning that you can’t take the bonus amount out of your account. However, you can use the bonus to play games and keep the winnings you accumulate.

The upside of a sticky bonus is that it often comes with lower wagering requirements, giving you more chances to hit that big win. Plus, it can give you more playing time since you’re not limited by the bonus amount.

Non-sticky bonuses can be withdrawn once you meet the wagering requirements, and you’re free to play with the bonus money as you please. However, a non-sticky bonus often comes with higher wagering requirements, so it’s important to read the fine print.

So which is the better choice? It really depends on what you’re looking for. Sticky bonuses are great for extending your playing time, while non-sticky bonuses offer more flexibility, so the decision ultimately comes down to your playing style.

Casino Promotions for Existing Players

It’s just as vital to reward loyal players who have been playing at the casino for a while as it is to reward new players who sign up. In the following section, we’ll go over various bonus offers available to existing customers.

Loyalty and VIP Programs

Many casinos offer loyalty and VIP programs to reward their most dedicated customers. These programs come with various perks, such as exclusive bonuses, personalised customer support, faster withdrawals, and even invitations to special events.

Casino loyalty programs are designed to reward players for their continuous play, typically based on a points system where players accumulate points with each bet they place. VIP programs are similar but generally offer even greater rewards and benefits to top players who meet certain criteria, such as a high volume of bets or deposits.

Cashback Bonuses

Cashback bonuses are a casino promotion where players receive a percentage of their losses back. It’s a way for casinos to give players a second chance by refunding a portion of their net losses.

Cashback amounts are often calculated based on a percentage of a player’s losses and credited as bonus funds.

Reload Bonuses

Reload bonuses are incentives that are only available to existing players who make subsequent deposits. These rewards match a percentage of a player’s deposit, increasing their bankroll and prolonging their playing time.

Referral Bonuses

If you love playing at online casinos and want to share the excitement with your friends, you’re in luck. Many online casinos offer referral bonuses for players who bring in new customers. That’s right; you can earn extra cash just by sharing the fun with your pals!

Casino referral bonuses typically come in the form of free spins, bonus cash, or even a percentage of your friend’s first deposit. So why not spread the love and earn some extra money in the process?

Seasonal Bonuses

As the seasons change, so do the bonuses! Casinos love to offer special handouts and bonuses during holidays and other special occasions, and these are known as seasonal bonuses. From Christmas to Halloween, Easter to Thanksgiving, and everything in between, you can find amazing deals that will make your gaming experience even more enjoyable.

Whether it’s free spins, deposit bonuses, or cashback offers, a seasonal casino bonus can give you a boost and help you win big. Keep an eye out for these special promotions and make the most of the holiday cheer.

Mobile Bonuses

Casino mobile bonuses are special promotions and rewards specifically tailored for players who favour playing casino games on their smartphones or tablets. They are meant to incentivise and enhance the mobile gaming experience and are frequently included in promotions for new games on the site.

Mobile bonuses might take the form of free spins, match bonuses, no deposit incentives, or exclusive mobile-only deals when you download the app. With the growing popularity of mobile gaming, mobile casino bonuses usually aim to attract new players or encourage existing players to try out the mobile platform.

Activation Through Bonus Codes

Bonus codes, also known as promo or coupon codes, are a combination of letters and numbers that activate a specific bonus or promotion when entered into the corresponding field on the casino website. Bonus codes can provide players with anything from free spins to deposit bonuses and more.

No deposit casino bonus codes are especially popular, as they give players the opportunity to try out a casino without having to risk any of their own money.

COMMON BONUS TERMS

While they can be a great way to boost your bankroll and enhance your playing experience, it’s important to understand the attached bonus rules. Here are some of the most common terms and conditions you should know before claiming your next offer.

welcome bonus icon

ELIGIBILITY AND ACTIVATION

To be eligible for a bonus, you’ll usually need to meet certain requirements, such as making a minimum deposit or using a specific payment method. Once you’ve met these conditions, the bonus will be activated, and you can start playing with the extra funds

bonus icon

EXPIRATION

Bonuses typically come with an expiration date, so make sure to use them before they expire. This could range from a few days to several weeks, depending on the offer.

GAME LIMITATION

Certain bonuses are only available for specific games or game categories. For example, free spins may be limited to specific slots, while live casino bonuses are only available for live dealer games.

MAXIMUM WINNING AND WITHDRAWAL LIMITS

When claiming bonuses, it’s important to be aware that certain offers may come with maximum winning or withdrawal limits. These limits set a cap on the amount you can win or withdraw from the bonus funds.
Maximum winning limits specify the maximum amount you can win from bonus funds, and any winnings exceeding this limit may not be eligible for withdrawal. Similarly, withdrawal limits set the maximum amount you can withdraw from your bonus winnings. If your winnings exceed this limit, you may only be able to withdraw up to the specified maximum.

MAXIMUM BET LIMITS

It’s vital to remember that any casino may impose maximum bet limitations on bonuses. These limits are often in place to prevent bonus abuse and ensure fair gameplay.
Bet limitations determine the maximum amount you can wager on a single bet while utilising bonus funds. As such, the maximum bet limits might change based on the specific offer and the casino’s terms and conditions.

welcome bonus icon

ONE BONUS PER PERSON/HOUSEHOLD/IP

Casinos usually have a policy of only allowing one bonus per person, household, or IP address. This means that people living in the same house or using the same IP address are unlikely to be eligible for the same bonus.
This approach ensures that each player has an equal opportunity to benefit from the available bonuses. It also aids in the prevention of fraudulent conduct and safeguards the integrity of the promotions.

WAGERING REQUIREMENTS

Most bonuses include wagering requirements, which means you need to wager a certain amount of money before you can withdraw any winnings from the bonus.

PAYMENT METHOD RESTRICTIONS

Some casinos may restrict certain payment methods from being used to claim a bonus. Each casino sets its own rules regarding the payment methods eligible or ineligible for bonus qualification. These restrictions are typically outlined in the terms and conditions of the bonus offer.

COUNTRY RESTRICTIONS

Please keep in mind that some bonuses may have country restrictions, limiting their availability to players from specific countries or regions. This information can often be found in the fine print of the bonus terms, so make sure to check if you qualify for country-specific bonus offers.

BONUS ABUSE

Responsible and fair play is crucial to avoid bonus abuse and safeguard your winnings. Casinos have strict measures in place to detect and prevent any misuse of bonuses. Therefore, violation of bonus conditions can result in the forfeiture of winnings.

Avoid actions that may be deemed as bonus abuse, such as creating multiple accounts, using fake names, and similar.

Wagering Requirements Explained

In the world of online casino bonuses, it’s important to understand the ins and outs of wagering requirements to make the most of your bonus offers. In this section, we’ll explain everything you need to know about wagering requirements.

How Do Wagering Requirements Work?

Wagering requirements are the number of times you need to play through your bonus before you can withdraw your winnings.

Different casinos have different wagering requirements, with some being more lenient than others. Some casinos may have a 30x or even a 40x wagering requirement, while others may have as low as 10x or no wagering requirements at all.

Calculating Your Wagering Requirements

Calculating your wagering requirements can be tricky, but there are plenty of tools available to help you out. We recommend using a wagering requirements calculator, which takes all variables into account and gives you an accurate figure.

For instance, if you receive a $100 bonus with a 30x wagering requirement and you play slots with a 100% contribution rate, your total wagering requirement will be $3,000.

Game Contributions

Different games contribute differently to your wagering requirements. Slots usually contribute 100%, while table games and video poker may only contribute 10% or less. It’s important to check the contributions before you start playing so that you can meet your wagering requirements as quickly as possible.

How to Beat Wagering Requirements

While there’s no surefire way to beat wagering requirements, there are a few strategies that can help. One method is to play low-variance games with a high RTP (return-to-player) rate. This will help you meet your wagering requirements while minimising your risk.

You can also try adjusting your bet sizes to manage your balance and extend games, tracking your progress in completing the requirements, and devoting time to gameplay to focus on wagering needs.

No Wagering Casino Bonuses

A no wagering casino bonus is exactly what it sounds like—an incentive that doesn’t require you to play through your bonus before you can withdraw your winnings. These bonuses are becoming more and more popular among players.

Choose the Best Casino Bonus

Choosing the right casino bonus can be overwhelming, but fear not! Here are some things to keep in mind when selecting the perfect bonus offers for you:

  • Minimum deposit amount: Make sure you know how much you need to deposit to activate the bonus. No one likes surprises, especially when it comes to their hard-earned money.
  • Legitimacy: You deserve to be safe while gambling, which is why it’s crucial to choose a reputable casino. We only recommend casinos that have passed our rigorous testing process, so you can rest assured knowing you’re in good hands.
  • Wagering requirements: Check the terms and conditions to see if the bonus has high or low wagering requirements. You don’t want to be stuck trying to meet unrealistic playthrough requirements, so make sure you choose a bonus that fits your playing style.
  • Game limitations: Some bonuses are only eligible for certain games, so make sure you pick a bonus that can be used on the games you enjoy playing.
  • Expiration date: Nobody likes a rotten apple, and the same goes for expired bonuses. Check the expiration date to make sure you have enough time to use the bonus before it’s gone.
  • Always keep in mind that picking the best casino bonus can significantly improve the fun and winning potential of your gambling sessions.

Pros and Cons of Using a Bonus

Looking to boost your bankroll and get more bang for your buck at the casino? A bonus can be a great way to do just that! But before you start claiming every bonus in sight, it’s important to consider both the advantages and disadvantages.

Advantages

  • Boost your bankroll: One of the biggest benefits of using a casino bonus is that it can significantly increase your bankroll, giving you more chances to win big.
  • A lot of choices: There are a wide variety of bonuses available for every type of player, whether you’re a high roller or a casual player.
  • Try new games: Bonuses give you the opportunity to try out new games without risking your own money, which is perfect if you want to explore and find new favourites.
  • Opportunity to explore new casinos: With the abundance of casinos available online, using a bonus can be a great way to explore new casinos and see what they have to offer. This can lead to discovering new favourite games or finding a new casino with better features or incentives.
  • No risk: Since you’re using the casino’s money, there’s no risk involved for you.
  • Opportunity for additional rewards: Many casinos have loyalty programs and VIP schemes that can provide additional rewards to players who use bonuses frequently.

Disadvantages

  • You can only cash out a certain amount: Most bonuses have a maximum cashout limit, so you won’t be able to keep all of your winnings.
  • Limited bonus time: Bonuses usually expire after a specified period of time, so it’s vital to keep that in mind if you want to claim them.
  • Playthrough requirements: Most bonuses have playthrough requirements, which means you’ll need to wager the bonus amount a certain number of times before you can withdraw your winnings. This can be a challenge for some players.

At the end of the day, the decision to use a bonus is a personal one, and it’s important to weigh the pros and cons before making a choice. Still, with the right approach, a casino bonus can be a great way to walk away with some extra cash in your pocket.

How to Make the Most of Your Bonus

You’ve just landed a shiny new bonus, but what’s next? With a little bit of know-how, you can turn that extra cash into big wins. Here are some tips and tricks to help you get the most out of your bonus.

Advantages

  • Look for bonuses with low wagering requirements. By opting for bonuses with lower playthrough requirements, you reduce the amount of gameplay needed to meet the criteria.
  • Understand the game contributions. Different games count towards the wagering requirements differently, so make sure you know which games will help you meet the requirements faster.
  • Play low- to medium-volatility slots. You’re more likely to land frequent, smaller wins, which will help you meet the wagering requirements without risking too much of your money.
  • Check the progress of your bonus. Many casinos have a bonus tracker that lets you see how you progress with your wagering requirements, so you can adjust your gameplay accordingly.
  • Forfeit the bonus if you hit a big win. If you hit a big win while playing with your own money, you may want to forfeit the non-sticky bonus and withdraw your winnings rather than going along with the wagering requirements on the bonus funds and taking risks.
