US Online Casino Promo Codes – What is a casino bonus code?

• bet365 USA – code USB365
• betMGM – code USDOTBET
• PartyCasino – use AGPARTY, new bonus code
• Borgata – casino codes NJBETBRGT (NJ) and PABETBRGT (PA)
• Betrivers – promo code USBTRV

Some online casinos require you to enter a unique code when you create an account. This is just to access a specific bonus or promotion.

Some casinos do this because they have numerous promotions running at once. Meanwhile, others list codes within their terms and conditions as one of the requirements you must meet.

Helpfully, if an online casino is running a promotion with a specific code, it will be published on the website’s homepage. It is also in the terms and conditions.

Promotional codes change regularly. So, you should always check that you have the current bonus code or risk missing the offer.

When do you enter the promo code? Even for online casino no deposit promo codes?

Typically, if you need to enter a promo code to access a welcome bonus, you must enter it as soon as you create an account.

In this case, you can write the code in the box when you submit your personal information.

Other casinos ask you to enter the code for your first deposit.

Again, if necessary, at this stage, you must type the code into the box provided on the screen. Often US Online Casino Promo Codes are not needed at all.

Casino Sign-up Bonuses: Other bonus terms to be aware of

If you’ve played at an online casino before, you will probably know that you often need to do more than enter a bonus code to access free money.

Usually, terms and conditions are part of the promotion. You should consider before taking advantage of the offer. Some things to look out for include:

Opt-in to US Online Casino Promo Codes

Often, online casinos require you to opt-in for their bonuses and promotions. This could be as simple as ticking a check box when creating an account.

However, you may also need to provide your email address to receive personalized offers. These, you can access with an initial minimum deposit.

If you get the option as you create an account at an online casino, always check the box to opt-in to offers and promotions.

You can always change your mind and remove yourself from the mailing list later on. However, it’s a handy step if you’re looking to maximize the bonus funds available to you.

Minimum deposit to qualify for Best US Online Casino Bonuses

Unless you’re accessing a no-deposit bonus, you must make a real money deposit to trigger the welcome package. Most of the time, you must enter the promo code when you deposit in the box provided. Other times, you must enter the code as soon as you create an account.

At most online casinos in the United States, the minimum deposit required to trigger a bonus is $10, but it can be as low as $1 and as high as $20 or $30 at some betting sites.

While you can deposit more than the minimum, make sure you deposit at least the required amount. Otherwise, you will forfeit your right to access the promotion.

Deposit method

You also need to consider your payment method to trigger the deposit. At some US casinos, e-wallet deposits via Neteller and Skrill are ineligible for the welcome package, so you should avoid these payment methods if stipulated in the terms and conditions.

This tends to be for anti-money-laundering reasons, so always check the terms before depositing.

To be safe, we advise you to add funds to your casino account via a debit or credit card. This is a safe, secure, and convenient payment method.

Practically all online casinos in the United States allow you to access the bonus when you make a real money deposit with your card.

Regardless, if you want to get the best US Online Casino Promo Codes, use a simple deposit method.

Wagering requirement to unlock best online casino sign up offers

After unlocking the welcome package with an initial deposit and the relevant promo code, you must consider the wagering requirement. This figure, given as a multiplier, indicates how much money you must deposit and wager before cashing out any winnings from the bonus.

At the top online casinos, the wagering requirement is as low as 1x.

This means you would only need to wager $10 of your cash if you unlocked a $10 welcome bonus.

However, some casinos stipulate wagering requirements of 30x or higher. Thus, you must check this before accessing the bonus so you know exactly how much it will cost you to access your winnings.

US Online Casino Promo Codes – Game eligibility for qualification

Another thing to check is the games you can play with your bonus funds. As mentioned, some online casinos offer numerous welcome packages. For instance, one might be for slot fans, while another might be exclusively for live dealer titles. The same is true when online casinos offer one promotion while a sportsbook offers another, as at FanDuel.

Therefore, you should always check that the promotion you’re accessing is available on games you wish to play. You will nearly always find slot games available from studios like NetEnt and Pragmatic Play.

However, you might also be able to play table games and video poker. Some casinos even permit you to play live dealer titles, but these games are often excluded.

US Online Casino Promo Codes – Timeframe for Completing Wagering Requirements

Last but certainly not least, you should check how long you must use the welcome bonus.

First, consider how long you have to enter the promo code and make a deposit after creating an account, which could be as little as 24 hours.

Then, look for how long you must use the funds before they expire. Finally, you will have to check how long you have to satisfy the wagering requirements. Most casinos offer seven, 14, or 30 days to play through the bonus funds before they disappear.

Three of the Best Casinos with US Online Casino Promo Codes

Though many online casinos offer promotions without requiring a promo code, below are three of the most prominent betting sites in the United States that offer you a generous welcome package as soon as you enter the relevant bonus code:

BetMGM Casino – The Top US Online Casino Promo Code & Sign Up Offer

• Code: USDOTBET
• Offer: 100% deposit match up to $1,000 + $25 on the house

BetMGM Casino is one of the leading gambling brands in the United States.

BetMGM’s casino offers over 1,500 superb slots, table games, and live dealer titles. The casino is available in Michigan, New Jersey, Pennsylvania, and West Virginia. When you sign up and create an account with the code “USDOTBET,” you will trigger a two-part welcome package.

The first is the no-deposit bonus, which provides you $25 in bonus cash without requiring an initial deposit.

The no-deposit bonus comes with a wagering requirement of just 1x. This is easy easy to play through if you land any winnings from the bonus.

Next, when you’re ready to make your initial deposit! You can trigger a 100% deposit match bonus of up to $1,000.

This bonus comes with 15x wagering requirements, which you must satisfy within 14 days. Slots contribute 100% towards the wagering requirements. So, you’re better off using this bonus to play these games rather than table games.

DraftKings Casino

• Code: DOUBLEDOWN
• Offer: Play $1 for $100 in casino credits

As a new player at the impressive DraftKings Casino, you can access a superb welcome bonus. When you create an account, enter the code “DOUBLEDOWN,” deposit it, and play just $1. You will instantly receive $100 in casino credits. You have seven days to activate the promotion after signing up, which you can do by depositing and entering the promo code, as explained above.

To withdraw winnings from the $100 casino credits, you must satisfy the 1x wagering requirement within seven days. For instance, you must wager at least $100 of your cash to play through any winnings before the credits expire.

Players in CT, MI, NJ, and WV can use the casino credits on any game at DraftKings. But, if you live in Pennsylvania, live dealer titles are excluded from the promotion. Given that you can unlock this welcome package with a bonus code and just $1, it’s highly attractive to all low-budget players.

BetRivers Casino

• Code: USBTRV
• Offer: 24 hours of casino losses back up to $500

The welcome bonus at BetRivers differs from many currently available at online casinos in the United States. Rather than matching your initial deposit, BetRivers offers to refund your casino losses within your first 24 hours of play, up to $500 if you live in Michigan, New Jersey, or West Virginia.

If you live in Pennsylvania, the bonus is a standard 100% deposit match promotion of up to $250. Both bonuses have an impressively low wagering requirement of 1x, which you have thirty days to satisfy.

When you sign up, you must enter the bonus code “USBTRV,” and any losses you incur during your first 24 hours of play, up to $500, will be returned to your account. The refund will show on the account dashboard within 48 hours for most players. For anything longer than this, contact customer support to chase up your refund.

Caesars Palace Online

At Caesars Palace, they’ll be giving you a $10 registration bonus in casino credit just for signing up with their online casino. The rollover requirements on this no deposit bonus are a bit more complicated than at other sites. You have seven days to meet the requirements.

If you choose to play slots, the rollover is a straightforward 1x. It doubles to 2x on video poker and up to 5x on all other casino games. Craps do not count against the wagering requirement.

DraftKings Bonuses

DraftKings is delivering to new online casino players $35 in no deposit casino funds. They’ll give you seven days to meet the 1x rollover requirement on this $35 in casino bonus play.

PokerStars Bonus

Also called the Stars Casino, they’re stepping up their no deposit bonus offer game in a big way. The PokerStars Casino will give new players a whopping $100 no deposit bonus. And there’s just a 2x wagering requirement attached to this wad of bonus casino play.

TOP Welcome Offers for New Online Casino Customers

What States Allow Online Casino Bonuses? 

Casino gambling online is currently legal in six US states. This changes all the time.

So, there’s a chance that more might legalize it shortly (Rhode Island is expected to join the list in 2025) 

For now, the states where you can play are Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, and West Virginia. All of these states allow bonuses and promotions, but it’s important to keep in mind that the bonuses might differ a little between the states. 

The best way to find out what’s available is to visit the online casino website through a link on this page and select your state. 

How to Sign Up and Claim Your Bonus 

You must create your online casino account before you can claim your sign-up bonus. You can follow our step-by-step guide to doing so: 

• Click on a link on this page to visit the online casino website. Make sure the platform is available in your state 
• Create your account (use your name, address, date of birth, email, and mobile number). Verify your account (using your SSN or by sending in your proof of ID and address documents) 
• Opt in and apply the promo code if required. Make your first deposit to claim your offer. Start playing. 
• Before you make a real money deposit to claim your online casino offer, you’ll want to ensure you understand all the T&Cs. These can vary between sites. So, the best thing to do is visit the terms of the promotion or the overall bonus T&Cs so that you’re completely prepared for the promo. 
• One of the key terms to look out for is wagering requirements. This refers to how many times you need to play through the bonus amount, deposit and bonus amount, or free spins winnings before you’ll be eligible to withdraw, and it can be around 35x at some online casinos. Certain games, like table games and live dealer options, don’t always count. 

Popular Casino Bonuses

While the sign-up bonus is often the biggest offer you can expect, top US online casinos know that regular players deserve to be rewarded, too. 

You can always head to the promotions section when you’re logged in or sign up for marketing emails to find out what’s available as a regular player. 

Many platforms operate a promotion calendar. For example, you might get free spins on a Monday and a deposit match on a Friday, while other casinos run more ad-hoc promos, so it’s always a surprise. 

VIP and loyalty programs are another popular way that casinos reward regular players. People who play often or for a lot of money sometimes get special offers or accumulate points that can be exchanged for freebies. Some casinos even offer priority support and invitations to special events.  

Matched deposit bonuses 

Most US online casinos offer new players a matched deposit bonus. This means that when you make your first deposit, you’ll get a certain percentage extra awarded in bonus funds. For example, if a site has a 100% matched bonus up to $100 and you deposit $100, you’ll have a total of $200 to play with. 

Look at the Bet365 or Borgata welcome offers, which give you a 100% match up to a whopping $1,000 when you make your first deposit.  

These funds are awarded as a casino bonus, so you won’t be able to withdraw immediately, and they might also have wagering requirements attached. Casino bonus funds are usually valid on almost all slot games, so you can choose how to use your free money. 

Free spins 

Some US gambling platforms include free spins as part of the welcome package. You might get these just for signing up (called a registration bonus) or need to make a qualifying deposit to get your spins. 

Free spins are generally awarded on just one game or a selection of a few, so although this is more limiting than a casino bonus, you might just get to discover a new favorite game. 

Cashback Bonuses

A cashback offer is a money-back guarantee. Some online casinos award you any net losses back after a certain period, like your first day or your first week, so if you haven’t been lucky at the start, you’ll get your losses back either as cash or as a casino bonus. 

Other online casinos are slightly less generous and award 10% or 15% of your losses back. Cashback offers are particularly popular at online live casinos, as live dealer games can often be excluded from standard casino welcome bonuses. A great example of a cashback offer is the BetRivers welcome offer, which allows you to claim back up to $500 in losses after your first day.  

No deposit bonuses

A no-deposit bonus is exactly what it sounds like – you don’t need to make a deposit to claim the offer, and it can take the form of a free casino bonus or some free spins. For example, when you sign up at BetMGM, you’ll get $25 in free casino bonus money before making a real money deposit.  

Please note that these no deposit offers are subject to change, and players should always check the casino’s official site for the most current terms and conditions.

Typically, the standard no-deposit bonus is a small stipend presented to the new account holder in the form of casino credit. The minimum amount is usually $10, with some sites offering as much as $25. On the flip side, the wagering requirement attached to these no deposit funds is generally minimal, often just a 1x rollover of the funds.

What Is A No-Deposit Bonus, And How Can I Claim One At An Online Casino?

A no-deposit bonus is exactly what it is advertised to be. You are getting an amount of cash from an online casino and all you need to do in order to access that cash is to open a new account with that online casino. 

This no-deposit bonus offer comes in a variety of forms. The most commonly-offered type of no-deposit bonus is an amount of cash that is to be used for casino bonus play. 

For instance, you’ll get a $25 no-deposit bonus if you open a new account with the BetMGM Casino in New Jersey. It’s $25 in casino bonus funds. Likewise, New Jersey players at the Borgata Casino online site will be rewarded with a no-deposit bonus of $20 in casino bonus play if they open a new account with the Borgata.

As a New Jersey online casino player, you can also access $30 in casino bonus funds from the Virgin Casino, $50 from the Bally Casino and $10 from the Tropicana Casino, also as no-deposit bonus offers.

Win Real Money Slots No Deposit – Online US Casino Offers

You’ll find that there are terms and conditions attached to these no-deposit funds. Of course, the money must be wagered in the online casino before it can be withdrawn from your account. Usually, the standard on no-deposit funds is a one-time playthrough requirement. Sometimes, the online casino will only permit you to keep winnings from wagers played with these bonus funds, and not the stake. 

The advantage to the player from a no-deposit bonus amount is that it gives you a chance to test out the new online casino you’ve just joined without the need to risk any of your own money.

Another popular no-deposit option is the chance to get bonus spins, again for doing nothing more than opening a new online casino account. In New Jersey, the Stardust Casino is offering online players 25 bonus spins for registering a new account with them.

Similar to the no-deposit funds, these free spins have wagering requirements. They usually are restricted to certain slot games and it’s likely you’ll have to bet any winnings from the free spins at least once. 

How Do Wagering Requirements Work For Online Casino Bonuses?

Whenever you are presented with some sort of bonus offer by an online casino, you should recognize that you aren’t getting those funds free and clear. To ultimately claim this money as your own, you are going to have to meet a predetermined standard of wagering requirements.

What are wagering requirements, you ask? That’s a good question. It’s certainly one you should always get answered prior to signing up with an online casino and accepting any bonus offer.

Also referred to as rollover or playthrough requirements, these wagering requirements are established by the online casino and revealed in the terms and conditions that accompany any online casino bonus offer. When they say always read the fine print, this is one of the reasons why you need to do just that.

The online casino is going to require you to bet the bonus funds a certain number of times before the money will be cleared for you to withdraw it from your account. And some of these wagering requirements can be quite restrictive. On average, the industry standard for playthrough is 15x. Some online casino games will contribute more quickly to clearing the bonus funds than others. Usually, slots are quicker to clear, whereas table games with their lower house edge won’t move you through the wagering requirements with the same frequency.

How Long Do I Have to Meet a Casino Bonus Wagering Requirement?

As well, the online casino is going to put a time limit on how long you have to meet these requirements and clear those bonus funds. It could be as little as seven days to as much as 30 days. 

Let’s look at a couple of specific online casinos to understand this concept with more clarity. For instance at BetMGM, the wagering requirement on their online casino welcome bonus offer of a matching first deposit of $1,000 is 15x the amount you received. Basically, what that amounts to is you’ll need to wager $15 for every $1 in bonus funds you receive. So if you got the maximum $1,000 signup bonus, you’re going to need to wager $15,000 to clear the bonus funds. And you’ve only got 14 days to meet this requirement.

By contrast, the BetRivers Casino only requires online players to meet a 1x wagering requirement. Granted, their welcome bonus is much lower. They’ll return to you between $250 and $500 in net casino losses over your first day of play. But you’ll only need to wager those funds once and they’ll be yours to keep.
