How Does An Online Casino Promo Code Work?

Picking a reliable online casino known for its high-quality service is a fantastic idea – that way, you’ll get an excellent all-around experience. Top operators lay out a red carpet for customers in the form of lucrative bonuses. You’ll spot these on the casino promotions page, and most are open to all customers.

However, other casino bonuses are more exclusive and require a unique code to access. Online casino promo codes add a layer of exclusivity to an offer while giving you more control over your participation. Usually open to new customers or VIP players, online casinos in the USA typically use bonus codes on special offers for specific users. 

Online casino promo codes are a combination of numbers and/or letters that you must enter into a box to redeem an exclusive bonus. Casino sites offer several different types of welcome bonus that suit players of various budgets and styles. When you register with an online casino, you will be asked to provide the bonus code to claim the site promotion. 

Once you enter the code, your casino will automatically apply the bonus to your account. Remember, you’ll still need to meet the wagering requirements and other T&Cs before getting the reward. It’s important to note that some online casino bonuses are automatic. This is convenient as it means you do not need to find the promo code. 

Although, with an automatic bonus, you have no choice but to participate in the promotion. Using online casino promo codes allows you to choose whether to claim the offer or not. And thanks to our page, finding promo codes for top online casinos has never been more straightforward. We’ve listed the best sites with the hottest bonuses alongside any promotion codes you need to access them. 

What Are the Best Sites for Online Casino Promo Codes?

Online casinos are never created equally, with every site offering something a little different. There are casino brands that offer more games, bonuses, payment methods, customer support options, and features. We list a wide variety of casino sites that offer online casino promo codes, from the big brands to smaller operators that are building their reputations. 

You are free to compare and pick from those, choosing the best based on your specific requirements. Still, it is best to start with the major operators, including our following top picks. Of course, every site we recommend is safe, legal, and regulated. 

FanDuel Casino

Known as one of the largest daily fantasy sports (DFS) providers since 2009, FanDuel Casino launched in 2021. This standalone casino provides a solid selection of games, flexible payment methods, and a classy mobile app. FanDuel Casino in Michigan, for example, is also known for unique promotions, including a generous welcome bonus. Offers are also plentiful for ongoing customers and include tournaments, reloads, deposit matches, and free spins. 

DraftKings Casino

Another DFS leader turned sportsbook/casino giant, DraftKings has been available since 2012, and its online casino followed several years later. One of the most trusted US casino operators, DraftKings Casino provides a massive selection of games from top software providers. Moreover, the operator is known for its large bonuses available to new customers and existing players. 

Caesars Palace Online Casino

One of the most iconic gambling brands, Caesars Palace Online Casino provides the same quality as the company’s land-based venues. Caesars Palace Online Casino in PA is an excellent desktop and mobile casino with a broad selection of real money slots online and live dealer options in its game lobby. Regarding promos, the casino has a generous welcome package and unique exclusive bonuses for returning customers.

BetMGM Casino

One of the most popular online casinos in the US, BetMGM has been in operation since 2018. The casino is one of the slickest-looking user experiences around, with a classy design and thoughtful UI. For example, BetMGM NJ online casino has regular colossal welcome bonuses that rank as some of the most generous casino promos in the United States. Importantly, BetMGM often uses a very accessible wagering requirement to make accessing the bonuses easier. 

Types of Online Casino Promo Codes

Grabbing one of our listed online casino promo codes allows you to take advantage of an attractive welcome bonus from a top casino site. Bonuses come in all shapes and sizes and will cater to all types of players. We recommend taking the time to get to know these different online casino bonuses. That way, you can make the best decision based on your requirements. 

Finding a bonus that suits your budget, favorite games, experience, and other gambling preferences. To help, we have put together the following list of the most common casino bonuses you can find online. Use these popular promos to understand what is available at the leading online casinos we recommend: 

Welcome Bonus

The main introductory offer at most online casinos is for customers who register for the site. Sometimes you will need casino promo codes to access the casino welcome bonuses, but often it is open to all players automatically. A deposit bonus is the most common offer as a welcome bonus. Here, the casino will reward you with bonus funds when you make a first deposit. For example, a 100% match on deposits up to $1000.

No Deposit Bonus

Sometimes you can grab a casino reward without depositing money into your gambling account. This is known as no deposit bonus and will usually be a smaller bonus with a higher wagering requirement. Still, if you meet the T&Cs, a no deposit offer is an excellent promo. Common types of no deposit offers include free cash, free spins, or free play. 

Loyalty Reward Bonuses

Many online casino operators provide a loyalty scheme that rewards customers for betting. Players accumulate points every time they bet. There are two types of loyalty schemes; one where you can redeem points for prizes and another where points help you progress through a level system, picking up increasingly generous benefits as you go. 

Mobile Bonuses

While most online casino bonuses will be accessible on both desktop and mobile, some of the best online casino apps and casino sites offer bonuses that are exclusive to mobile players. These offers will be available when you access the casino through dedicated mobile casino apps or an HTML5-optimized browser. Remember to check the T&Cs to see if an online casino promo code is needed to access the bonus at the top mobile casinos

free spins

Free Spins

Online slots are the most popular games at online casinos, and the best slot sites have hundreds or even thousands of slot games. A free spins offer is a very popular type of casino bonus. It's found at free spins casino sites and caters directly to slot players. As the name suggests, the casino operator will give you free stakes on specific slot games. You can only use your spins on games selected by the casino. Plus, there will be bet and win limits alongside the wagering requirement of these slot bonuses. 


Cashback bonuses are rare and are usually only available to invited VIP players. But if you can find one, this is one of the best online casino promos for US players. For every wager you place, the casino will provide a percentage amount back over a defined timeframe. Cashback can be anywhere from 5% to 50% of the money you spend, depending on the casino site.

Casino Promo Codes For Existing Customers

Bonuses are not only for new people who register with a site. Online casino operators understand it is vital to keep their existing customers happy. This is why most casino sites have a rolling roster of promos, such as slots bonus offers, free spins, reload bonuses, tournaments, and more.

Online casino promo codes are also available for other types of casino bonuses. For example, refer a friend is a bonus where the casino will reward you with a small reward if you recommend another player. This person will need to register and deposit with the casino before you receive your bonus.

How Do I Choose the Best Online Casino Promo Code?

There is no doubt that casino bonuses can grab your attention in an instant. However, it is essential that you do not randomly and blindly claim bonuses without getting more information. Every casino promo has specific terms and conditions you must meet before claiming the offer. This can range from clear restrictions and rules to playthrough requirements. 

Your main goal should be finding a casino bonus that meets your individual needs. That does not always mean the promo that has the biggest rewards. In fact, if a promo looks too good to be true, it often is. It is best to check your casino budget and look for a bonus with requirements that match what you can afford to play. But don’t worry; while it can be confusing, there are excellent bonus opportunities that are both attractive and accessible. 

You also need to select bonuses that are available on the games you prefer to play. For example, if you are a blackjack player, it's best to choose one of the best blackjack casinos online and potentially snag a smaller offer than to choose a bigger bonus from a casino that has fewer blackjack games, or bonuses that can't be used on blackjack. 

And, of course, we are here with our expert ratings. Our team only recommends the best casino offers with the most generous T&Cs. When browsing the top online casino promo codes and bonuses we highlight, look for details on the following bonus rules:

Wagering Requirement

This is the playthrough amount you must meet before cashing out winnings you made through the bonus. For example, if a promotion has a 20x wagering requirement for a $20 bonus, you will need to wager $20 a total of 20 times. That means a total wagering commitment of $400 (20 x 20). 

Bet and Win Caps

Casino bonuses essentially give you something for free once you meet the playthrough requirements. To prevent players from taking advantage of promotions, casinos will often cap how much you can bet or win when using bonus funds/spins.

Expiration Dates

Online casino bonuses are not available forever. There will be a strict time limit on your promotion. This will be a timeframe that you have to claim the deal, such as 7 days or one month. Once this time passes, you will no longer be eligible for the bonus, even if you are working towards the wagering requirement. 

Game Weighting

You must play casino games to meet the playthrough requirement. It is worth noting that gambling sites will weigh games differently in terms of how they contribute to the wagering requirement. Slots are usually 100%, while table games such as blackjack and roulette are between 5% and 50%. Some games do not contribute at all.

Ultimately, the golden rule of casino bonuses is always to read the small print. By understanding the T&Cs, you can redeem online casino promo codes in confidence and on your terms. 

Online Casino Promo Codes to Avoid

It can be challenging to spot the online casino bonuses you should avoid. Some legitimate and excellent promos have massive rewards and generous terms. Sometimes, something looking too good to be true is not a suitable measurement. Luckily, you can learn to avoid bad quality or even fake bonuses by paying attention to these tips:

  • Avoid high wagering requirements
  • Read the T&Cs always
  • Only choose bonuses from licensed casinos
  • Select one of the online casino sites we recommend

Online Casino Promo Code Wagering Requirements

If you have been browsing online casino promo codes and their related bonuses, you will have seen the terms “wagering requirement” time and time again. This rule is attached to 99.9% of all casino promotions online. A wagering requirement is the number of times you must play through a bonus amount. 

More specifically, you must play before the bonus amount a set number of times before you can cash out winnings you made with the bonus funds. Casino operators or online slot sites use different wagering requirements, so the playthrough commitment will change from casino to casino and even from bonus to bonus. 

how to

Let’s imagine you see a welcome bonus offering a 100% deposit match of up to $200. If your first deposit is $200, the casino will match your deposit by 100%, so $200 in bonus funds. For this example bonus, let’s say there is a wagering requirement of 30x. Therefore, you’ll need to wager the bonus amount thirty times before withdrawing related winnings. 

So, that means you will need to wager 30 x $200, which amounts to $6,000. In other words, you must spend $6,000 before you can cash out any winnings you made with your $200 bonus. That may seem a lot, but you can meet the wagering requirement by depositing, winning games, and reinvesting your winnings. 

Of course, in many cases meeting the wagering requirement will mean using a lot of your own deposited cash. Although, if you have big winnings from your $200 bonus, it may be worth meeting the commitment. 

It is essential that you know the wagering requirement before you start playing for a bonus. The obvious next question is, what is a good or lousy wagering requirement? Well, in some ways, it depends on your individual budget and how much you can spend on wagering. Even so, some wagering requirements are high, making a bonus hard to achieve. 

A wagering requirement over 40x is starting to get high, while anything under 35x is a good deal. More importantly, the wagering requirement must be realistic, giving you a fair chance of making the most of the bonus.

How to Use an Online Casino Promo Code

Now that you have the best online casino promo codes from leading gambling sites, it is time to put them to use. We asked our team of casino industry experts to put together the following simple tips for using online casino promo codes:

Research Online Casino Promotions

Remember – knowledge allows you to make the best decisions for your individual needs. Compare the best online bonuses by checking out our list of recommended online casinos. Read the T&Cs of all promotions you want to claim and pick the bonuses that match your budget and game preference. Also, remember to avoid offers with a super high wagering requirement. 

Register at Your Online Casino

Select one of our recommended online casinos and click the link to head directly to the website. Hit “Register” and complete the sign-up process, which involves providing information such as your name, address, phone number, email address, and the last four digits of your SSN. 

Activate Your Online Casino Promo Code

During the registration process, the casino will ask you to provide the bonus code if one is needed. Input the promo code in the available box to opt-in to the bonus. Remember, some online casinos do not require a bonus code. If that is the case, you will be entered into the offer automatically. 

Fund Your Casino Account

It is now time to make your first deposit. Top online casinos provide a selection of payment options to cover the needs of players. Available payment methods will differ from casino to casino, but common financial options include debit and credit cards, bank transfers, e-wallets such as PayPal and Skrill, ACH, and prepaid cards. 

Deposits will be free and clear into your casino account instantly. As for withdrawals, different casino payment methods have varying timeframes for clearing your money. For example, e-wallets may complete withdrawals within a few hours, while debit/credit cards can take up to 5 business days. 

Play Online Casino Games to Use Your Promo Offer

With your account funded, you can now play games to meet the wagering requirement and claim your bonus winnings. Remember to check the wagering requirement and eligible games to play towards your bonus. 

Withdraw Your Winnings

You can now cash out your bonus winnings when claiming online casino promo codes. To do this, you’ll first need to verify your ID and address. This is a basic rule for first withdrawals at all online casinos. Send a copy of your ID (driver’s license, passport, etc.) and proof of address (utility bill, phone bill, bank statement, etc.)
