Types of Online Casino Promotions and Bonuses

When you sign up to any of the aforementioned offshore casinos, you can expect to be greeted with all manner of bonuses and promotions. Generally speaking, these promos are easy enough to understand. But, in case you’re an absolute newcomer to the world of online gambling, we’ve listed out exactly what each type of bonus is below:

Welcome Bonus

This is the online casino bonus given to a newcomer to the site. Typically, the welcome bonus comes in the form of a matched deposit bonus or a risk-free spin or chips. A risk-free spin is pretty much self-explanatory – it’s just free money or a free spin.

A matched deposit bonus is when the house matches your original investment, generally up to a specific amount. So, if you deposit $500, the casino will match it, giving you $1,000 to bet with.

Very few slots slots casinos go higher than a $1,000 matched deposit bonus in our experience.

No Deposit Bonuses

These bonuses are always greatly appreciated since they don’t involve the bettor having to actually deposit any money. No deposit rewards tend to be free spins on the slot machines, free chips at the poker or roulette table, and so forth.

Free Spins

What are free spins? As the name suggests, oftentimes best online casino bonuses enable users to spin 25x/50x/100x for free on one particular (or many) of the slot machines. Free spins are regularly included alongside bigger offers, such as no deposit codes ruby slots.

You keep what you win, but do pay attention to the specific wagering requirements put into place by your casino of choice, since it’s not always so easy to withdraw this cash even after the best online casino promos (more on that down the page under the ‘How to make a profit from online casino bonuses heading).

Recurring Bonuses and Promotions

Online gaming sites tend to shower repeat players with freebies and exclusive offers. The idea is to also encourage continued wagering. Most US online casinos do this by offering recurring promotions such as monthly bonus promotions and time-sensitive offers on specific games. You’ll also find reloads and weekly promotions on targeted games.

High Roller Casino Bonus Offers

Big spenders have a special place at US online casinos, and with good reason. By spending huge amounts, they play a significant role in the casino’s growth. As such, online casinos are prepared to go to great lengths to keep high rollers content.

Because high roller bonuses target players with deep pockets, they comprise large bonus amounts of $1,000 or more. Among other benefits, a dedicated personal manager tends to their gaming needs on the site.

VIP Casino Bonus Rewards

Many online casinos design VIP programs for their most loyal players. These VIP programs are made up of multiple tiers players must work through to accumulate points. The more you play, the more points you earn, and the more rewards you receive.

VIP programs typically offer bonuses of their own. For instance, VIP players will receive cashback rewards, payout boosts on select games, or big deposit match bonuses.

Game Specific Bonuses

It’s not unusual for US casinos to use bonuses as a way of encouraging players to check out featured games. In most cases, this is done to promote the game in question. From the player’s perspective, these bonuses offer numerous rewards.

For starters, you get to play the newest games with free money. Exclusive rewards such as free spins or VIP points are also up for grabs. But more importantly, you get to broaden your knowledge of different games without risking much money.

Mobile Casino Bonuses

Mobile casino bonuses are fast becoming popular with US online casinos as operators reward you for playing with your mobile device. You essentially receive a bonus for accessing the online casino app using your Android or iOS device. Other casinos incentivize players who download the mobile app.

Most online gaming sites provide these bonuses via push notifications. Players would, therefore, need to activate their SMS notifications so they don’t miss out. You receive this bonus either as free spins on a specific slot game or as a deposit boost.

Other Casino Bonuses

Existing Customer Casino Bonus Offers

Online casinos understand the need to keep existing players busy on their sites and stop them from exploring competitors’ products. One of the ways they do this is by consistently offering bonuses, keeping current players’ accounts well-funded. Let’s have a look at the most popular existing customer casino promotions.

Reload Bonus

Reload bonuses are the most popular offers online casinos reserve for their repeat players. A reload bonus is much like a deposit match offer usually provided to new players. The major difference is players receive this bonus for adding more money to their already existing player accounts. Also, its value is smaller than that of the welcome offer.

Referral Bonus

With some online casinos, referring your buddies to join has its perks. You receive a bonus in cash or free spins for your troubles. However, in most cases, the referred party must not only join but make an initial deposit.

Happy Hour

Instead of traditional promotion deals, some online operators offer happy hour promotions on specific slots. During this happy hour, players can enjoy free spins for select slot titles or a boosted match on deposits they make on the site.

What is an Online Casino Sign-Up Bonus?

Casinos with sign up bonus offers use these rewards to encourage players to register. Depending on the site you register at, you could receive anything from free spins to bonus funds. And many times, casinos will make the bonus even more irresistible by offering a combination of rewards. Although certain sites may only reward you when you make your first deposit, it’s becoming more and more common for casinos to offer welcome packages.

However, you should always take the time to read the terms and conditions. This is because you may need to use promo codes and there are some bonuses that can’t be triggered by every payment method accepted at the site. If you rush ahead and make your first deposit without knowing exactly what needs to be done, you could end up missing out on your reward altogether.

What are Signup Bonus Codes?

When you decide to claim a casino welcome bonus, it will either automatically be credited to your account when you make your deposit or you will need to use a bonus code. Bonus codes are unique combinations of numbers and letters that are used to help the casino differentiate between various offers. In some cases, you may be able to use a single promo code to trigger every portion of a welcome bonus, or you will need to use different ones each time.

Using the wrong code or forgetting to use the code at all could result in you missing out on the entire package. This is because many casinos only allow those who’ve claimed the first deposit bonus to qualify for the rest. It’s also worth noting that new casinos who are trying to compete for players’ attention could also offer a casino welcome bonus code that allows you to claim no deposit bonuses.

Mobile Casino Sign-Up Bonuses

These days, not everyone is able to enjoy online gaming at their desktops as they’re forever finding themselves on the go. This is one of the reasons casinos like the ones we’ve recommended have made sure that all of the rewards and games can be enjoyed on desktops as well as mobile devices. By registering at these sites, you’ll find that all of the welcome offers can be enjoyed on iOS and Android devices. All you have to do is use your device’s browser to sign into your account and make a deposit.

How Casino Bonuses are Calculated

The top rated casino bonuses almost all include percentage based incentives for signing up and depositing. These do not include an exact figure which will be credited to your account, so can sometimes be a little bit difficult to work out.

Ultimately, this is how they work. If you get a 200% bonus offer on deposits up to $1,000, assuming you use the maximum deposit amount, you will get $2,000 from your chosen online casino promotion, after you have completed the rollover/wagering requirements.

Be careful if you want to utilise the entire offer though. Ordinarily, you will need to use the offer all in one, as it will only apply to one deposit. So if you wanted to make the most out of all $1,000 for the offer, do not deposit any less to start with, or the offer may well have expired by the time you come to deposit again.

Comparing the Best Online Casino Bonuses

Best Payment Methods to Use for Online Casino Bonuses

The table below outlines all of the deposit options you can use to claim the best online casino promos.

Online Casino Promotion Stipulations

Casinos introduce rules to protect their interests when offering bonuses to players. These rules can vary in their strictness.

Time Limits: Casino bonuses often have time limits, like 60 minutes, within which you must use them; otherwise, unused bonus funds are lost.

Win Limits: Casinos set limits on how much you can win with bonus money, so always check the terms and conditions.

Wagering Requirements: These requirements indicate how many times you must play with your bonus before withdrawing winnings. High requirements can make it tough to cash out. Always scrutinize the fine print.

How do Wagering Requirements Work?

Wagering requirements are those which must be met in order to unlock your full bonus amount. They are the most frustrating part of the best online casino promos, but are worth it once your bonus is unlocked afterwards.

These tend to range between 20-50x the number you deposit. Let us give you an example:

If your deposit is $1,000 and your wagering requirement is 20x, you will need to place $20,000 worth of bets on your chosen best online casinos in order to get your bonuses credited to your account. Online casino offers always require such wagering, but they are clearly laid out in the terms and conditions of every promotion.

What’s the Wagering Requirement or Rollover in a Sign Up Bonus?

The term wagering requirements refers to the number of times a player must wager their deposit amount and/or bonus funds before they will be able to withdraw their bonus and any money they win. Casinos do this to prevent themselves from losing money if a player decides to claim a free reward and withdraw it straight away. It’s important to note that there are two main types of wagering requirements you’ll come across. You may have to wager your bonus funds as well as the amount you deposited or you’ll have to wager just the bonus amount a certain number of times.

For example, let’s say that one of the casinos you’ve registered at rewards new players with a sign up bonus of 100% up to $500 and the bonus terms state that you need to wager the bonus amount plus your deposit amount 30 times. If you deposit $200 and receive $200 in bonus funds, the minimum wagering requirement will be $400 x 30 which equals $12,000. And if instead the bonus terms state that only the bonus funds need to be wagered 30 times then the minimum wagering requirement will be $200 x 30 which equals $6,000.

General Sign Up Bonus Terms & Conditions

Before you claim rewards at casinos with sign up bonus offers you should always read the bonus terms. However, we understand that it can be complicated to make sense of the different rules. This is why we’ve listed examples of the general rules you’ll find at casinos with sign up bonus offers.

• Bet Limits: This refers to the minimum and maximum bet limits you need to stick to when wagering with bonus funds.
• Qualifying Games: Only certain games can be played with bonus funds and not all of the games will contribute towards wagering requirements.
• Promo Codes: Certain casinos with sign up bonus offers will require players to use a promo code. This is a combination of random numbers and letters that can be found in the bonus terms.
• Wagering Requirements: This refers to the number of times the player must wager their deposit and/or bonus amount. If you don’t meet these requirements in time you’ll lose your bonus funds and any money you may have won.
• Max Bonus Amount: The maximum bonus amount that can be claimed at casinos with sign up bonus offers.
• Expiry Times: Most bonuses will expire after a certain period of time. And if you don’t meet the wagering requirements before your bonus expires your bonus funds and winnings will be removed from your account.
• Minimum Deposit: This is the minimum deposit needed in order to qualify for a specific bonus. Note that just because your payment method allows you to make a deposit of $10, for example, doesn’t mean that the minimum deposit needed to trigger your offer will be the same.
• Excluded Payment Methods: Not all casinos will allow deposits made with specific methods to qualify for bonuses. The list of excluded methods will be found in the bonus terms and conditions.

Online Casino Bonus Games

In order to maximize the fun and potential for winnings, online casino bonus games are a great shout. There’s European-style roulette, bingo, sic-bo, Magic 8s, blackjack, and tons more where that came from.

These bonus games can be plenty of fun and are a good way to spend more time at the house, enjoying your casino welcome bonus but without blowing your account.

Las Atlantis is atop the pile when it comes to bonus games and is well worth checking out if the above sounds of interest to you.

Online Poker

Ignition have a bonus which is activated specifically by playing poker on their platform. Poker is the second biggest online casino game behind slot machines, and there are always plenty of options to play the card game.

Classics such as Three Card and Texas Hold ‘Em are available on all sites, but many will host their own variations. Moreover, live casino options enable you to play poker alongside a real dealer and other virtual players. Often, the best online casinos will host their own poker tournaments, so make sure you look out for those fun opportunities.

How to Make a Profit from Online Casino Bonuses

After obtaining your online casino welcome bonus, avoid giving it all back. Here are ways to maximize your profit:

Wagering Requirements on Free Spins

Free spins on slots might seem like an easy way to profit from your welcome bonus, but watch for wagering requirements in the fine print. Some casinos offer free spins without set requirements, while others, like MyBookie, have lower ones. Beware of casinos requiring a high number of spins, such as x100, before cashing out.

Don’t Abuse the Bonuses

Online casinos aim to keep their new customers happy, but they don’t give out free money endlessly. Despite appearances, the casino wants its bonus back with your money on top. Rules have been established to prevent abuse, including limits on maximum stakes when using bonus funds. Exceeding these limits may result in the casino refusing to pay out or even closing your account.

Don’t Go in with Guns Blazing on the High Rolling Slots

Stick to low or medium variance slots for better odds. High variance slots are more challenging to win on. While there’s always a chance of hitting a jackpot, it’s riskier. For beginners, longer sessions on low variance slots help build skills and familiarity with the platform, improving your chances for future bonuses.

How to Sign Up & Claim a Welcome Bonus

You’ll be redirected to any of our preferred casinos should you click on any link or image on this page. Once there, the signing up process is fairly simple. But we’ll detail it step-by-step below too, just to aid you along your path to claim the best online casino bonuses.

We’ve opted to do the guide via the Wild Casino, but the process is nearly identical to any other online casino bonus codes you decide to pursue.

Step 1: Basic Information

To create your account, simply click on the “Join Now” button on the casino homepage. On the next screen, you’ll be asked to give some basic information about yourself. Fill in your name, date of birth, and adddress before clicking on the ‘next step’ button.

Remember, you have to be over the age of 21 to legally gamble in the USA. So stop at this point if you’re not of legal age.

Step 2: Choose a Payment Options

Now choose whether you’d like to make your first deposit with Bitcoin, Credit Card or an Altcoin.

Step 3: Select Deposit Amount & Enter Your Bonus Code!

The third and final step involves selecting the desired deposit amount, entering the provided bonus code, and then clicking “deposit now.”

In this example, we’re maximizing the WildCasino welcome bonus by depositing $1,000 using the code “INSIDERS”. This action triggers the “250% up to $1,000” welcome bonus, which adds an extra $2,500 in bonus credit to our wagering balance.

What Makes a Casino Sign Up Bonus Good or Bad?

As we mentioned, we’ve compared numerous bonuses to present you with the best casinos with sign up bonus offers. And to show you how we determine which sign up bonuses are good or bad, we’ve provided a few examples of the points we take into consideration.

The Bonus Percentage

When you claim a deposit match bonus you should always consider the bonus percentage. Because your bonus amount will depend on how much you deposit as well as the bonus percentage, it’s important to make sure that you’re able to make the most out of your deposit amount by claiming a welcome offer that allows you to double or even triple your money. By taking the time to compare different bonus percentages you can work out how much you’d like to play with and plan your deposit amount accordingly, allowing you to get more for less.

The Wagering Requirements

Checking out the wagering requirements is one of the main ways you can tell whether or not a bonus is a great option for you or not. Although opting to claim low wagering bonuses is always a good idea, just because a bonus has higher-than-usual wagering requirements doesn’t mean that it’s automatically a bad bonus. This is why we always recommend looking at whether you have to wager your bonus funds and deposit amount or just the bonus funds as well as how many times the total sum will need to be wagered before you’ll be able to withdraw.

The Runtime

You should never go ahead and claim a reward at online casinos with a free sign up bonus without considering whether or not you’ll have enough time to meet the wagering requirements. Bonus funds expire, and even though lower wagering requirements of 35x seem easier to meet compared to wagering requirements of 40x, for example, there’s no use in claiming a reward if the bonus expires within a few days. Working out the wagering requirements as well as the runtime goes hand in hand when trying to figure out whether or not you should claim a specific offer.

Maximum Bonus Amount

To get the most out of offers available at online casinos with free sign up bonus offers the first thing you need to ask yourself is how much you can get out of it. Claiming the maximum bonus amount is always a good move as it provides you with a lot more gaming credits for a much lower deposit. The best rewards available at online casinos with free sign up bonus offers will always offer large max bonus limits.

Accepted Payment Methods

So many players have made deposits at online casinos with free sign up bonus offers only to find themselves confused because they didn’t receive the promised amount. Although there are a few reasons this could happen, most of the time it’s because they neglected to ensure that the payment method they used qualifies for the welcome bonus. Every casino is different and although not all of them will limit the number of payment methods that can be used to claim rewards, there are some that do.

How to Pick the Best Online Casino Bonuses

Every casino bonus we have listed can potentially be lucrative for those who sign up using them. Even so, there are some which may stand out to you than others. Though there will of course be some personal preference involved, there are certain elements that will likely appeal to the majority.

The first of those is by looking at the rollover requirements. Regardless of how much the deposit bonus is, you will have to meet the rollover requirements first. As such, if you complete the full deposit amount (often $1,000) and have a 35x rollover as is most commonplace, you will have to place $35,000 worth of bets before earning your bonus. Therefore, those best online casino promos which require only 20x worth of rollover are often the most alluring.

Equally, find an offer that applies to your payment method. More often the crypto bonus is better than the debit card or traditional payment bonus. However, this is not the case everywhere.

Tips for Using Your Online Casino Bonus

Even the best online casino bonuses are of no value if you don’t know how to use them optimally. Here are five tips to take advantage of casino bonuses to the fullest.

• Deposit Maximum Bonus Amount: Deposit the maximum amount to receive hundreds or thousands of dollars in free cash, providing more wagering opportunities.
• Check Out Ongoing Promotions: Keep an eye on ongoing promotions to ensure you don’t miss out on new offers.
• Don’t Ignore Existing Promotions: After the welcome offers, explore existing deals, which often bring significant benefits to your gaming experience.
• Read the Fine Print: Be aware of terms and conditions associated with online casino bonuses, such as no deposit bonus codes like ruby slots. Ensure you understand how the bonus works before claiming it.
• Switch Casinos If You Have To: You’re not bound to any one online casino. Feel free to switch casinos if your current one doesn’t meet your needs. Explore better deals on our recommended list to enhance your gaming experience.

Conclusion: The Best Casino Welcome Bonus

Exploit the best online casino bonuses you can find, keep your ears to the ground for the best weekly and monthly codes, and enjoy the thrill of wagering. With specific reference to those precious free chips, spins, and deposit bonuses, our personal favorite casino would have to be Wild Casino, for its never-ending stream of casino bonus codes.

The best casino bonus will depend entirely on your play style and preferences. Slots players will love free spins, but live casino players will likely prefer matched deposit bonuses.

What casino is paying out the most right now?

Yes, you certainly can. Most online casinos offer a mobile-optimized webpage where you can freely claim a casino bonus the same way you would using the desktop browser page. Some casinos even offer mobile-exclusive casino bonuses from time to time.

How do online casino bonuses work?

Online casino bonuses work by requiring a player to unlock a high value incentive. They usually insist on wagering requirements which a customer must meet in order to gain a reward on their first deposit, usually fairly lucrative. This ensures the casino is happy because they are gaining regular custom via their wagering requirements, while the player will gain a substantial bonus once they have unlocked it.

It would seem obvious that the biggest bonuses represented the best casino offers, but this might not always be the case. The higher the value offer, the larger the wagering requirements are likely to be. As such, you may have to play more, and thus deposit or spend more of your own cash to actually unlock it.

What are the best online casino games with signup bonuses?

For most signup bonuses, you will be able to play any games. However, the best online casino games are often the slots and poker, as these sometimes have specific bonus offers attributed to them. This is more of a rarity with table games such as blackjack.

How do you calculate the value of an online casino bonus or promotion?

The best way to calculate the value of any online casino bonus is to consider what the bonus offers and weigh it up against any wagering requirements to see if you are likely to make any profit.
