Reviews of the Best Online Casinos for Sign Up Bonuses

Even though we believe that each of the casino welcome bonus offers available at the sites we’ve listed above are certainly worth considering, we also understand that no two players are the same and what may seem like a minor downfall to one player may be a complete deal breaker for another. This is why we always encourage readers to compare the various pros and cons of the sites they’d like to register at.

To help you out, we’ve put together a little more information about what you can expect from the bonus departments as a new player at the offshore casinos we recommend.

1. Las Atlantis – Biggest Casino Welcome Bonus Available Online

Las Atlantis’ aquatic-themed hotspot takes the top spot on our list of the best casinos for bonuses for a number of reasons. For example, new players have the chance to kickstart their fun with an impressive 280% deposit match bonus that can equal up to $14,000 in bonus funds – the largest welcome offer we’ve come across. These funds can be used to play almost all of the slot games featured on the site and come with a high but achievable 35x playthrough requirement.

But there’s plenty more where that came from. We suggest regularly checking Las Atlantis promo codes to see exactly what’s on offer when you come to sign up since the deals change frequently. But, as an example, at the time of writing, players can also benefit from an additional up to 165% crypto slots bonus on select titles, as well as boosted percentages and unique deals on new games.

There are over 150 slot games to keep you occupied at Las Atlantis, plus a keen slate of table games, including 16 variations of video poker. Most featured games can count towards your playthrough requirement but do check. the Terms and Conditions to be sure. Las Atlantis accepts deposits and pays out via fiat, crypto, or eWallet transactions – again some bonuses are currency specific so do check the small print.

 

2. Wild Casino – Offers the Best Casino Welcome Bonus

Whether you’re a crypto gambler or prefer to wager and win with traditional payment methods, Wild Casino has the perfect casino welcome bonus for you. Although we certainly recommend taking advantage of the generous Bitcoin reward that allows you to claim almost double the amount on offer to players who prefer using traditional methods, the standard welcome bonus is also an excellent choice. Unlike many other sites we’ve reviewed in the past, the terms for both casino welcome bonus offers are very reasonable. For example, when you claim the standard bonus, you’ll benefit from low wagering requirements.

What makes this bonus even better is that you’ll also be able to play a wide variety of games using your bonus funds. However, you should note that when it comes to meeting wagering requirements, only certain online slots contribute 100%. As a member of this casino, you have a lot more than just the welcome bonus to look forward to. Not only will there be loads of reloads but from time to time you may even be able to use Wild Casino no deposit bonus codes to claim free rewards.

 

3. Bovada – Exclusive Welcome Bonus for Using BTC

Number three on our list of recommended Casinos with sign up bonus offers is Bovada. Many US players are familiar with this casino because of the exciting rewards on offer to crypto players. And as we started taking a closer look at the special new player reward for BTC users have to admit that we were impressed with what we discovered. By using a special Bovada Casino bonus code, you’ll get a much better bonus compared to what you’ll receive if you make your first deposit with a classic casino payment method instead.

Although this casino has a lot to offer new members, you should take the time to consider a few of the minor downfalls we came across before you decide whether or not you’d like to claim this offer. For example, if you’re a live dealer fan, you may be disappointed to find that live games don’t contribute towards wagering requirements. And unlike other sites, there are quite a few games that can’t be played using your bonus funds.

 

4. MyBookie – Offers One of the Best Deposit Match Bonuses

As a premium casino site, we were a little stunned to find that although crypto players will be able to claim two excellent reload casino bonuses a week, there are no targeted special offers for those who wish to use crypto to make their first deposit. However, this is easy to look past when you consider how rewarding the 150% up to $750 casino welcome bonus is. When you use the special MyBookie Casino bonus code to trigger your new player bonus funds, you’ll be able to use these funds to play a wide range of games.

What we found interesting as we did a little more research about this site and its welcome bonus was that, at 40x, the wagering requirements may seem high at first. However, it’s actually not as bad as it seems because although players will need to wager the bonus funds a large number of times, unlike many other sites that require players to wager the bonus funds plus the deposit amount the same number of times, you will only need to wager your deposit amount once at MyBookie Casino.

 

5. El Royale – Seven Different Welcome Bonuses Available

What players will love most about El Royale Casino is that returning players aren’t the only ones with a long list of offers to choose from. And when you decide to fund your casino account for the first time, you’ll be able to use any of the seven El Royale Casino bonus codes to claim exciting sign up bonuses. These options are perfect for players who prefer using standard payment methods as well as those who’d like to take advantage of the perks that come with using crypto to game online.

The only thing that may annoy some players is that every one of the casino welcome bonus offers include a set of free spins. Now, this isn’t a complete train smash if you enjoy spinning the reels. However, it may be if you’re not that into slots and would like to enjoy other casino games instead. This is because you will need to meet wagering requirements for both the deposit match and free spins portions of the offer which means that even if you’re not that into slots, you will still have to spend money playing them if you’d like to meet the wagering requirements and withdraw your bonus funds along with any money you win using them.

 

6. BetOnline – Choose Between Three Welcome Offers

Last but not least on our list of recommended casinos with sign up bonus offers is BetOnline. As we worked our way through our BetOnline Casino review, we were pleased to find that it’s put a great deal of effort into ensuring that no matter what type of casino games you enjoy playing most, you’ll be able to enjoy them with free funds. When we reviewed the three welcome offers available to new players, we found that most of them have very low wagering requirements and allow gamers to meet them within a reasonable time period.

However, we did come across a few drawbacks that could make players hesitate when it comes to claiming any of these rewards. For example, not every game available at BetOnline will contribute towards wagering requirements. And if that isn’t limiting enough, the bonus terms state that when you use free funds to play games, you will only be able to use them on Betsoft casino games.

 

7. Everygame – Exciting 5-Part Bonus for New Players

What made this site stand out from all of the other casinos with sign up bonus offers we’ve listed was the fact that there are a number of offers to choose from. The one we felt was the most rewarding was the offer listed under “Casino Red”. This welcome bonus gives you the chance to enjoy exciting rewards when you make your first five deposits. This reward can be triggered with a low deposit and can also be used to enjoy a range of mobile casino games.

Just remember to read through the terms and conditions carefully as there are special Everygame Casino bonus codes that may need to be used to successfully claim your deposit bonus. Although we found that there are a number of unique options to enjoy after you’ve claimed your bonus, we were disappointed to discover that not all of the games available at this casino can be played using bonus funds. So, before you decide whether or not to claim, make sure you’re able to use your casino welcome bonus to play your favorites.

 

8. Super Slots – Low Wagering Welcome Offer Available

Many players shy away from claiming bonuses because they simply feel that the wagering requirements are too high. However, when you register at Super Slots, you’ll have the opportunity to claim a low wagering bonus when you make your first deposit. Unlike many of the other casinos with sign up bonus offers we’ve recommended, Super Slots offers not one but two rewards for new players to claim. If you choose to claim the standard reward, you’ll have the chance to use a Super Slots bonus code to enjoy a generous deposit match when you make your first six deposits.

Those who prefer to gamble with methods like Bitcoin will also have an exclusive offer to consider. And although it only rewards you when you make your first deposit, you will benefit from one of the best deposit match bonuses available online. The only issues we found while exploring the bonus terms for these offers was that not all games can be played using your funds. And only casino slots will contribute 100% towards wagering requirements.

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.

Types of Online Casino Sign Up Bonuses

When you start checking out different offshore gambling sites you’ll notice that there are quite a few different types of casino welcome bonus offers. Next, we take a look at examples of popular rewards you’ll find at online casinos with sign up bonus offers.

Match Deposit Bonuses

Most of the online casinos with free sign up bonus offers will offer a match deposit bonus. This type of offer will reward you with bonus funds when you make a deposit. And the bonus you can expect to receive will completely depend on the amount you deposited into your account.

For example, let’s say that you’d like to claim a casino welcome bonus of 100% up to $1,000. When you make a deposit of $500, you’ll receive a 100% match based on that amount. This means that you’ll get an additional $500 credited to your bonus balance, giving you $1,000 to spend on exciting online casino games.

Free Spin Bonuses

If you enjoy the thrill that comes with playing online casino slots then you’ll want to keep your eyes peeled for casinos with sign up bonus offers that include free spins. Free spins are great because it allows you to enjoy even more game time which could lead you to your next big win.

However, you should note that you will almost always have to use these spins on specific slots. Although this can seem like a bit of a drawback, the games that need to be played using these bonuses are often extremely entertaining and rewarding.

No Deposit Bonuses

Not all online casinos with sign up bonus offers will require players to make a deposit to claim the reward. And although no deposit bonuses are pretty rare in general, if you do manage to stumble across one it’s a great opportunity to try out the real money games on the site without having to spend any real money right away.

Usually, all you need to do is create an account. However, just because you don’t need to make a deposit doesn’t mean that there are no wagering requirements. It’s also important to note that no deposit bonuses may be a great way to game online for free, however, the rewards aren’t usually as big as what you can expect from a deposit bonus.

Bitcoin bonuses

These days, most casinos with sign up bonus offers will have two rewards available for new players. You will find a standard offer that can be claimed using traditional methods. And a bonus that can only be claimed using crypto like Bitcoin. A Bitcoin casino welcome bonus allows you to enjoy much bigger rewards and they’ll also usually have better terms.

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.

• 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.

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.

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.

Best Payment Method for Casino Sign Up Bonuses

Being able to use your preferred method to claim online rewards is important. This is why you’ll find that online casinos accept a range of different methods. However, each of these methods come with advantages and disadvantages which is why you should always compare a few before deciding to use a specific one. Here we’ve provided a little more information about the popular methods players use to claim welcome offers online.

Crypto

These methods are used by hundreds of players in the US as many casinos offer exclusive crypto bonuses. Bitcoin casino bonuses will allow you to enjoy much bigger rewards compared to what you’d receive if you used an alternative method instead. You’ll be able to enjoy speedy deposits and withdrawals with zero transaction fees. And what makes it even better is that you won’t have to enter any financial information to claim your reward.

eWallets

Although E-Wallets aren’t as popular today as they were a few years ago, many players still prefer using these methods. This is because no financial information needs to be shared and withdrawals are processed quicker than most alternatives. However, if you’d like to use an E-Wallet to claim a welcome bonus, you should note that there are some casinos that don’t allow players who use methods like Cash App, Skrill and Neteller to qualify for welcome offers.

Regular Payment Methods

Almost every casino we’ve come across accepts methods like Visa and Mastercard. And although traditional payment methods are safe and easy to use, you should consider the possible drawbacks that come with using them to claim welcome bonuses. For example, you will probably be able to claim your reward by making a credit card deposit, however, most of the time you can expect to pay a pretty hefty transaction fee.

If you’d like to make a deposit with classic payment methods like credit cards, you’ll receive an excellent deposit match. And if you prefer crypto instead you have a much bigger reward to look forward to.

You’ll be able to use these bonus funds to play a range of games and when it comes to runtime you have more than enough time to meet the wagering requirements and withdraw your big win. This is why we recommend Las Atlantis to anyone in the US looking to find the ultimate welcome bonus online.
