Best Online Casino Promos for 2024

Following a detailed cross-examination of the market, we’ve highlighted the best online casino bonuses in the US below. As you can see, most of them feature first deposit matches, casino credits, free spins, or a combination of these. Besides being generous, they also come with player-friendly terms and conditions.

If you want to make the most of the best online casino promos, we recommend that you consider some key criteria, such as wagering requirements, validity periods, and eligible games and payment methods. Stay tuned to learn how to choose the offer that’s most suitable for you based on these factors.

Most Popular Types of Casino Bonuses

The best online casino bonus offers come with different requirements and amounts, and each of them caters to different player preferences. A few common examples are sign up promos, free spins, and cashback deals. You can review the most popular types of casino bonuses in the table below:

We’ve selected promotions from the best online casinos, so the quality of both the platform and the offer are unquestionable. You get attainable wagering requirements, adequate validity periods, and sometimes exclusive bonus codes for even more attractive offers. Now let’s review each bonus in more detail.

Sign Up Bonus

As suggested by its name, you can only claim this bonus upon registering with a new platform and making your first deposit. Typically, such offers may include a deposit match (capped at a specific amount) or free spins (a specified number). In the case of BetMGM online casino, for example, the latest welcome bonus is a combination of the two.

Cashback Bonus

This is one of our personal favorites, as it gives you a portion of your losses back in the form of cash or bonus funds. Let’s give you an example – imagine that you sign up with a platform, deposit $150, and incur losses of $100. A cashback bonus may give you 10% back, which would be $10. Virgin Casino has an offer of up to $100 real cash back.

Free Spins Bonus

Free spins are extremely common at online casino sites, and they are the perfect bonus for slot enthusiasts. Due to their nature, we also recommend them to newbies. Essentially, free spins allow you to play your favorite slots without having to use your own funds. Stardust Casino online will give you 200 free spins on Starburst upon your first deposit on the site.

Refer-a-Friend Bonus

A refer-a-friend bonus will give you a reward for every new player you refer to the site. This could be in the form of cash or some casino credits. At Caesars Palace Online Casino, both you and your friend will receive $100. Before that, however, your friend must have deposited and wagered a specific amount of money.

No Deposit Bonus

It’s in the name – you can claim such bonuses without having to make any deposit. This is perfect for inexperienced players or if you want to test a new platform, as you don’t have to take any unnecessary risks. No deposit bonuses are rare and usually smaller in value – e.g., 50 free spins or around $25-$50 оn the house.

Other Types of Online Casino Promos

In addition to the best casino promos we already discussed, there’s a range of other bonus types you can find online. Some of them are more suitable for newbies, while others are targeted at advanced players. There are also offers for high rollers, low rollers, and so on. We’ve included a few recommendations below:

If you’re playing at the best online blackjack casinos, you might find suitable bonus offers, although they are less common than welcome bonuses. The same applies to the top roulette sites and any other platform. That’s why you should carefully review the available promotions and their terms, consider your gambling preferences, and then decide which offer to claim.

How to Claim a Bonus

It’s generally quick and straightforward to register at an online casino and claim a bonus. To make things even easier, we’ve prepared a short step-by-step guide to help you orientate yourself. What’s even better is that you can skip steps 1-3 if you’re already registered with the casino.

1. Step Enter your email address and create a password
2. Step Enter your personal data
3. Step Activate the account
4. Step Head to the ‘promos’ section
5. Step Choose a bonus offer
6. Step You’ll need to make a deposit to trigger a deposit match bonus
7. Step Meet the playthrough requirements within the validity period
8. Step Turn your bonus into real cash

Make sure that you enter correct, verifiable information to avoid any future inconvenience. You should also read the T&Cs of any bonus you’re thinking about claiming. Check if things like wagering requirements and validity period work well with your gambling style. Ensure that the offer can actually add value to your play.

How to Choose the Best Online Casino Bonus Offers

When it comes to the best casino bonuses online, there’s a set of criteria you should consider. Start with the offer’s value and proceed with its terms and conditions, including the minimum required deposit, wagering conditions, eligible games, and payment methods. As gambling experts who assess the highest payout online casinos, we always include these in our evaluations.

Playthrough Requirements

The playthrough requirements are crucial and can make or break a bonus. Simply put, you won’t be able to withdraw your bonus winnings if you don’t meet them. Also known as wagering conditions, they are expressed as a multiplier and indicate how many times you’ll need to play through the bonus money.

For example, if you claim a $10 bonus with a 10x wagering requirement, you’ll need to wager $100 before you can withdraw any bonus winnings. It’s best to avoid offers with playthrough conditions of 50x or more, as they are often difficult to meet. Additionally, focus on playing eligible games with high contributions.

Bonus Validity

Most bonus offers have validity periods, meaning you’ll have to use the bonus funds and complete the playthrough requirements within a specified time frame. Watch out for short promotion periods, as they tend to work against you. Anything lower than 14-30 days is already a bit dicey.

Let’s take a promotion period of 7 days. Even if you deposit $20 on a %100 match bonus with a low wagering requirement like 10x, that’s still $200 you have to playthrough by the end of the seventh day. The validity periods vary from bonus to bonus and casino to casino, so pay attention to that.

Minimum Deposit

Regardless of whether you play at VIP Preferred online casino websites or anywhere else, most bonuses have low minimum deposit requirements. That’s usually equal to the overall minimum deposit amount on the site, but it may vary from platform to platform and across the different promotions.

In our personal experience, this will usually be around $10-$20. At most casinos that accept Venmo, for example, the minimum deposit amount is $10. If you’re lucky enough to come across a no deposit bonus offer, you’ll be able to play entirely risk-free, which is an excellent opportunity.

Overall Bonus Amount

Oftentimes, the bonus amount is a maximum that can only be activated by a matching deposit. So, if a casino offers a 100% deposit match up to $1,000, then you need to deposit the $1,000 to get the full amount. Of course, you can also make a deposit of $10 and receive an extra $10 to play with.

If you’re having difficulties calculating how much you can get from a particular bonus or how much you’ll have to wager before being able to withdraw any potential winnings, you can use our bonus calculator. All you have to do is enter a few details, such as the minimum required deposit, wagering requirements, etc.

Eligible Games

Every bonus comes with a list of eligible games, which you can find in the corresponding terms and conditions. Different types of games usually have different contributions towards the fulfillment of the wagering requirements. While US online slots normally contribute 100%, roulette and blackjack games have a contribution of about 20%.

Live dealer tables, on the other hand, oftentimes have no contribution whatsoever. It’s your responsibility to check if your favorite games are exempt before claiming an offer. This will make your gambling experience a lot easier and way more pleasant. Another thing to check is if deposits with your preferred payment methods count for claiming the bonus.

Bonus Calculator

We built a free bonus calculator to help you decide if an offer’s worth it. It takes out all the guesswork and makes things way easier for you. Simply add the required details (available in the T&Cs) to find out if the amount you need to wager is actually more than the free and total play money you receive. A top casino bonus should give you a realistic chance at withdrawing more money than you spend.

If you’re using the online casino bonus calculator, double-check if the playthrough requirement is based on just the bonus or the bonus + deposit and select accordingly. This way, you’ll make sure that the results are accurate. It’s more common for the wagering conditions to be based on the bonus alone, but there are exceptions.

Responsible Gambling Practices

Remember that you should always gamble responsibly and stick to predefined budget and time limits. Don’t go chasing bonuses, regardless of how attractive they may seem. Hardly anything comes for free, and every online casino promotion has strict terms and conditions you have to familiarize yourself with.

If you or anyone you know is struggling with signs of compulsive gambling, you should seek help immediately. You can add yourself to a self-exclusion list at the state level and also call or text the national hotline 1-800-GAMBLER for direct contact with support. There are many other NGOs like Gamblers Anonymous and Gambling Therapy.
