Quick Start Guide – Understanding Online Casino Bonuses

The best casino bonuses are not the ones that offer the best value but the ones that have fair and understandable terms. This is essential for players, as understandable details mean they can easily learn how to qualify for each offer, how to use it, and how to prepare for a cashout. It takes a lot to understand casino bonuses fully, but don’t worry – we have all the details.

 

Things to Look Out For When Claiming a Casino Bonus

When you start reviewing a new online casino, all of the bonuses can look interesting to you. What you need to understand is that upon registration, the first bonus you will be eligible for is the welcome bonus.

 

This one is triggered with your first deposit or, in the case of welcome packages, your first few deposits. We recommend reviewing this bonus first and deciding if you want to claim it. Only look at the other bonuses after you decide on the welcome bonus.

 

When you decide which bonus you want to claim first, also check the deposit requirements tied to it, including the minimum deposit you need to make and any possible restrictions on deposit methods. We’ve found that many bonuses limit the use of e-wallets like Skrill or Neteller for qualification, so it’s better to check for such limitations before making that first deposit.

 

Wagering Requirements

The wagering requirements can make or break your experience with casino bonuses. They tell you exactly how much you need to invest after using a bonus if you want to cash out the winnings. This is because bonuses are credited as bonus money, and all winnings you make are in this type of bonus money before you complete the rollover.

 

Bonus rollover can usually be set between 20x and 40x, which is within industry standards. At a rollover of 40x, a bonus that provides $100 in winnings will require an investment of 40 x $100 or $4,000 in total before you can request your payout.

 

Sometimes, casinos choose to set different wagering requirements on bonus cash and free spins winnings, with the latter usually carrying a higher rollover. The only time you don’t need to worry about the rollover is when you claim and play with a no-wager bonus, which allows you to withdraw whatever you win immediately.

 

Win Caps & Time Restrictions

If you find a bonus you like and get a good boost to your budget, that doesn’t mean you can use the cash to make all the winnings possible. Most bonuses set a cap on how much you can win, which is usually the case with free spins winnings.

 

Then, there are time restrictions as well, telling you how long you have to use the bonus before it becomes void. The limits are usually more lenient for bonuses that include cash prizes, and they can extend up to 30 days. With free spins, you will usually get around 24 hours to use the spins, depending on the size of the batch. You’ll also need to complete any rollover within these limits if you want to keep your winnings.

 

Bonus Payout Types

There are various ways that bonuses pay out. In the case of all deposit match bonuses, including welcome offers and reloads, you get the bonus as soon as you make your qualifying deposit. Cashbacks and weekly offers are available only on specific days of the week. Usually, all of these limitations will be carefully written out in the bonus details, so we recommend being extra careful and reading everything closely to maximize your offer.

 

Regional Restrictions

Some of the bonuses you will find at online casinos can be restricted to specific countries and available in others. This usually happens at offshore or international online casinos that are available in multiple countries. These casinos can choose to offer exclusive bonuses for players from specific countries, while in others, they limit the use of bonuses, depending on local laws. Depending on where you come from, you should check the bonus details to learn whether you can qualify for a bonus you’re interested in.

Daily & Weekly Promotions

Besides one-time offers that you can only claim once at an online casino, there can also be recurring promotions in the form of daily and weekly bonuses, which you can claim multiple times in your journey at the casino.

 

Usually, these recurring promotions are reloads and cashback offers, along with specific daily offers that are tied to minimal deposits. You can claim batches of free spins on Tuesday, a small amount of bonus cash on Thursday, and cashback that lands for losses over the weekend. The specific requirements depend on the casino you are using, so it’s best to check the details and see what the qualification process is and what type of prize each offer includes.

Type of Online Casino Bonuses

Now that we’ve seen some of the details that are common for online casino bonuses, we can move on to the most popular types of bonuses you will come across. These offers can take so many shapes that it can really take some time before you understand the features that make them distinct. But we are here to offer some help, explaining the basics about each of the best casino bonuses:

Welcome Bonus

The casino welcome bonus is the best way for a casino to welcome new players. This offer is usually the first one that will be advertised to you upon registration, offering you a boost for a qualifying first deposit at the casino. But this means that the offer is only available for your very first deposit, and after that, it will become void.

 

The welcome bonus can take all kinds of shapes, but usually, it includes a match on your first deposit up to 100% and a specific sum, which can be $1,000 or even more. There can also be some free spins tied to the offer, but they usually come as a no deposit offer you get for claiming the welcome bonus.

 

Sometimes, casinos like to be extra generous with new players and create a complete welcome package that includes boosts for the first four to five deposits. With such offers, you can choose to claim only the first deposit bonus or the entire package, depending on your preference.

Deposit Bonus

An online casino deposit bonus is a bonus that you can trigger with a qualifying deposit. This means that the bonus only becomes available and is credited to your account after you deposit into your account, but you might also be required to use a bonus code in some specific cases.

 

We’ve found that most deposit bonuses offer a match on your deposited amount up to a specific sum, just like we explained with the welcome bonus. This means that for a deposit of $20 and an offer of 100% up to $1,000, you will receive an additional $20 that you can use alongside your initial deposit to wager in the game lobby.

Free Spins

Free spins bonuses are the perfect offer for players who like to explore slots. Sometimes, these offers can come as standalone offers, meaning you will need to make a minimal deposit to trigger a batch of free spins. Other times, they can be tied to larger offers such as deposit match bonuses, reloads, etc. But as we’ve found often to be the case, larger batches of free spins are divided into smaller ones and released on consecutive days – which keeps things interesting for longer!

 

With free spins bonuses, the most important thing is to check whether there are any game restrictions that tell you which games you must play with the bonus spins. Other than that, it’s also wise to check the maximum wager per spin and the maximum amount you can win when playing with the spins.

No Deposit Bonuses

One of the most highly sought-after bonuses is the no-deposit offer, a reward that you can trigger without depositing any real money into your account. This type of bonus can include free spins, bonus cash, or both, but the amounts will usually be smaller than on deposit offers.

 

The thing about no deposit bonuses is that you can earn them by completing some simple milestones. It can be verifying your profile, adding your phone number, downloading the mobile app, enabling notifications, or joining a social media profile that gets you that boost.

 

Whatever the case, make sure to look out for high wagering requirements on these offers. Using the specific details, you can decide if an offer is worth the hassle.

No Wager Bonuses

Quite rare but still a great type of offer, no wager bonuses usually come in the form of a deposit match offer or cashback bonus that you are free to use immediately after activation. As soon as you use the entire amount, you can choose to withdraw all winnings without playing with them in the casino lobby. This means a smaller investment on your part and a quicker way to access your winnings, which is why many players choose to activate these bonuses whenever available.

Reload & Cashback Bonuses

Reload offers are deposit match bonuses tied to existing users. You can’t claim them with your first deposit, as that one is reserved for the welcome offer, but you can do it using any of your following deposits. As a match deposit bonus, it often comes with a match on your deposit up to a specific amount, but there might be free spins involved as well. Something to check with these bonuses is whether they are tied to deposits made on specific days. Sometimes, the reload offer can only be claimed with the first deposit of the week, while in other cases, it might only be tied to deposits made over the weekend.

 

As for cashbacks, they are a type of offer that allows you to claim a part of your lost wagers over a specific timeframe. When you activate a cashback offer, it calculates the exact amount you’ve lost on that day or the entire week, and then it returns a percentage of around 20% to 50%, but there can also be an actual limit on the amount you can receive as cashback. Many players choose to activate cashback bonuses because of the low wagering requirements, usually around 1x to 5x, which means the winnings are easy to release.

VIP & Loyalty Bonuses

Do you know what the difference is between a VIP and a loyalty club offered at an online casino? Well, the loyalty club is open to all players upon registration, meaning you automatically become a member, and you collect points by playing games and claiming bonuses. The more points you collect, the higher you’ll climb in the club.

 

As for the VIP club, this is the most prestigious club in the casino, and it only accepts the most valued members. You might be able to qualify after reaching specific milestones, but most casinos make these clubs invite-only, so you never know who gets in and how they do it.

 

Each of these clubs can offer specific bonuses, including personalised offers, higher cashbacks, more daily offers, and rewards for climbing to a new tier. The offers are a variety of deposit match bonuses and free spins offers, along with some no-deposit and no-wager bonuses, to make things interesting.

High Roller Bonuses

High roller bonuses are best for players who have a large budget and are not afraid to use it. While these bonuses generally follow the deposit match format, it’s important to note that qualification is more challenging, as deposits usually start at $300 to $500, while regular offers might require you to deposit as little as $20.

 

This means that high roller bonuses are challenging to trigger, but the benefit of those who decide to complete the qualification is that they can earn bigger prizes of several thousand dollars. You might find high roller offers as reloads or a welcome high roller bonus, depending on the casino you choose to focus on.

Mobile Casino Bonuses

Mobile casino bonuses are specific offers given to players who choose to access the casino from their mobile device. This usually excludes players who use the casino website and is tied solely to the dedicated casino app. Upon installation, you can find the specifics about the mobile bonuses, which may otherwise be unavailable on the website.

 

Of course, claiming a mobile bonus means that you will also need to make a deposit using your mobile, so it is most convenient to use GPay or Apple Pay, or an app tied to an e-wallet. These payment options also process deposits instantly, so you can see the funds in your account quickly and use them to activate and play with the offer.

Referral Bonuses

Referral bonuses are quite common at online casinos and give you a boost whenever you refer someone to the casino. If there is a referral program, you can get a unique link tied to your account that lets the casino see that you are the one who has referred the new player.

 

Still, it’s important to note that you usually don’t receive the reward after sending someone the link. The casino will require the new player to use the link to register and make at least one deposit at the platform to release the bonus. But then, you and the player can usually receive a small but helpful boost to your budget, so it’s really a win-win if you ask us!

How We Rate the Best Casino Welcome Bonus Offers

Usually, online casinos offer a single welcome bonus reserved for new players, but there can also be platforms that provide you with multiple options. We are not talking about welcome packages but several different welcome offers – each catering to various types of players, whether regular users, crypto enthusiasts, or high rollers.

In this case, you should consider which option is best for you using the details tied to each offer. Whenever we come across platforms that offer multiple casino welcome bonuses or we want to compare the offers between different casinos, here’s what we focus on:

Game Eligibility

An essential thing we look into is whether bonuses come with game restrictions. This is usually the case with bonuses that offer free spins, especially no-deposit or no-wager offers. They are generally sponsored by a game provider that wants to promote some new title, which is why the exact offer is tied only to one or several titles from that provider.

There can also be bonuses that don’t have eligible games listed, which means you can use them on whatever game you want to. These are better if you have your mind set on a specific game you want to play, but if you have no preferences and would gladly explore some new titles, even bonuses with game restrictions can come in handy.

Available Payment Methods

Similar to what we mentioned about the game eligibility, specific bonuses can put limitations on the deposit methods you can or cannot use with the bonus. This is essential, and it’s best to check it before you actually try claiming the offer, as you might not be able to qualify using some specific payment method. Usually, it’s e-wallets like Skrill and Neteller that are not eligible for bonus qualification. Still, some bonuses can also limit you to using cryptocurrencies if you want to get your reward.

Casino Reputation and Security

Sometimes, the flashiest offers come from casinos that are best avoided because of a history of unpaid winnings, terms that are challenging to meet, account closure issues, etc. So, carefully picking which casino you will play at is also something that you should think about.

At Casino Crest, we review only the best platforms available on the global iGaming market. Even if we come across any platform that we deem doubtful, we will tell you so that you can avoid it. We always pay special attention to security features offered at online casinos, and we check for the presence of a valid gambling license, KYC checks, secure payment processing, 24/7 support, AML policies, etc.

Reasonable Terms and Conditions

Each bonus comes with its own details, so we make sure to go over them before claiming and recommending any offer. In these details, you should be able to find everything relevant to the offer, including the exact qualification procedure with the minimum deposit and any payment method limits.

Then, it’s essential to check how the casino wants you to use the bonus – whether there are any game limitations, bet limits, and the timeframe after which the bonus expires. You’ll also need to learn how to release your bonus funds after using the entire reward, meaning if there’s a cap on how much you can win, the wagering requirements, etc.

If the details tied to the bonus seem limited, make sure to check for a separate bonus policy or the general terms and conditions that could share additional information.

Wagering Requirements

The wagering requirements are the most important part of a casino bonus. They tell you how many times you need to use your winnings in the casino lobby before you can turn them from bonus money into real money that’s withdrawable.

The industry standard wagering requirements can be up to 40x on both the bonus cash and the winnings from free spins. Anything above that will be too challenging to complete, meaning it will take a lot of money to complete. We recommend sticking to offers with lower wagering requirements, as those will be easier to complete and prepare for withdrawal.

Perks of Claiming an Online Casino Bonuses

We get it – sometimes, you think about claiming a casino bonus and wonder whether it’s actually worth it to go through the hassle. We always recommend claiming all possible online casino bonuses that fit your budget and come with fair terms. Many great perks come with playing with bonuses, including the following:

 

  • Increased bankroll: You usually make a minimum deposit to get twice the money with a deposit match bonus of 100%. In the case of a no-deposit offer, you don’t even invest any of your own money to get extra cash or free spins. So, in the case of most bonuses, you get a great bankroll boost that can help you play at the casino for longer.
  • Reduced financial risk: Bonuses always give you extra cash or free spins that you can use to make casino winnings without investing additional cash. This means lower financial risk for you, but still a great chance to rack up some great winnings.
  • Opportunity to try new games: Especially in casino bonuses that provide you with free spins, you get the chance to test new games without investing any of your own money. Some bonuses that come with game restrictions limit you to specific games, but all other bonuses are free to use on whichever games you prefer.
  • Higher chances of winning: Having all that extra cash and bonus spins to work with makes you eligible for additional wins. In the case of high RTP games, you can also rely on high returns with time, which means that even when investing money, you can still get a great return on your investment.
  • Comp points accumulation: When you are a part of a casino’s loyalty or VIP program, playing with bonuses and exploring more games in the lobby means you get extra points that help you climb up the tiers. This also makes you eligible for exclusive perks that come with the higher tiers.

How to Claim the Best Online Casino Bonuses

Found a bonus you really like? It’s time that you claim it by following a few simple steps. While the exact qualification process varies depending on the specific offer you choose, we will give you some general recommendations that will help you understand what it takes to trigger the best casino bonuses.

 

  • Find a casino that’s trustworthy and is working under a valid gambling license. This ensures that you can expect a fair experience throughout, including with the casino bonuses.
    Register at the casino and complete your profile with the verification process. Even if verification is not mandatory upon registration, we recommend completing it early on so that you can avoid prolonged payment processing later on.
  • Open the promotions tab and check all offers. Decide which ones you want to qualify for early on, including whether the casino welcome bonus is something you are interested in. Once you find the offers you are most interested in, read the details to learn more about the qualification process of each one.
  • Take the steps needed to trigger your preferred offer. If you’re qualifying for an online casino deposit bonus, make the qualifying deposit by adding the minimum amount or more using your preferred deposit method. Make sure to check for any deposit method restrictions on e-wallets or other options.
    If the bonus isn’t automatically activated upon qualification, try contacting the support team to learn how long it will take before it is credited, or ask them to trigger it from their end.
  • Make sure that you’ve made the right deposit and that you’ve used any promo code tied to the offer.

 

By following these few quick and easy steps, you can receive most offers at popular online casinos. At Casino Crest, we are always available for additional explanations and help in case you get stuck trying to trigger any offer or use a casino. So, don’t hesitate to reach out and get help with any aspect of online casinos.

Stay Updated!

Staying up to date with the latest online casino bonuses is crucial in order to have the best experience at your favorite casinos. Some of the best bonuses are often available only for a limited time, which means that staying informed about what the top choices are can greatly enhance your chances for big wins.

 

Here at CasinoCrest, we are here to help you out with that by constantly making sure to provide you with the best offers that you can claim and start spinning. Check back regularly, so you don’t miss any of the great online casino bonuses we feature here!

Online casino bonuses are worth it as long as they come with fair and transparent terms and conditions. They give you a significant boost to your gambling budget, whether in the form of free spins, bonus cash, or both.

Online casino bonuses work by triggering prizes whenever you complete a set milestone. Sometimes, bonuses can be triggered with qualifying deposits, while in the case of no deposit bonuses, you need to complete specific goals to receive your prize.

The best online casino bonuses often depend on your preference, but usually include no deposit bonuses, no wager bonuses, and deposit match bonuses with fair terms. Ultimately, you are free to choose the specific types of bonuses you want to activate.

There isn’t a simple answer to this question, as all online casinos you’ll find recommended at Casino Crest have rewarding bonuses with fair terms and conditions. Feel free to take your pick from any of them, but make sure to read the fine print on the promotions before qualifying.

Often, casinos don’t allow you to claim multiple bonuses at the same time, but you can certainly do so over time. Just ensure that you don’t activate two or more bonuses at the same time, and try not to use bonus cash to activate additional offers.
