How Does an Online Casino Promo Code Work?

Picking a reliable online casino known for its high-quality services 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 them on the casino promotions page, and most are open to all customers.

However, other 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. You must enter into a box to redeem any exclusive codes. 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. 

Most bonuses are best used for online slots sites. They can be used on table games, but generally they only contribute 20-50% to the bonus.

Once you enter your real money casino promo code, the bonus is automatically applied 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 you can qualify for some online casino bonuses automatically. This is convenient because you don't need to search for an exclusive casino promo code. 

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, promo codes for online casinos has never been more straightforward. We’ve listed the best sites with the hottest bonuses alongside any bonus codes you need to access them.

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 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 Bonuses

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. Some casinos even offer a 200 dollar welcome bonus in some occasions.

No Deposit Bonuses

Sometimes you can grab a free promo codes casino reward without depositing money into your gambling account. This is known as online casino no deposit bonus and will usually be a smaller bonus with a low wagering requirement. 

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. 

VIP Bonuses

Many online casino operators provide a VIP loyalty program that rewards customers for betting. Players accumulate points every time they bet. There are also two types of loyalty schemes. One is where you can redeem points for prizes. Another is where points help you progress through a tier system, picking up increasingly generous benefits as you go. 

Mobile Bonuses

Most bonuses will are accessible on both desktop and mobile. However, some of the best online casino apps and casino sites offer bonuses exclusive to mobile players. 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

Online slots are the most popular games at online casinos, and the best slot sites have hundreds or even thousands of slots. A free spins offer is a very popular type of bonus at online casinos. Some casinos even offer 120 free spins for real money in the USA

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

Cashback casino 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 Bonus 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.

One example is a refer-a-friend bonuses, which is when the casino will offer you 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 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. Check your casino budget and find a bonus that fits what you can afford. There are attractive and accessible bonus opportunities available.

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. This way, you can potentially snag a smaller offer while avoiding a casino that has fewer blackjack games. What's more, certain bonuses may not even be eligible 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. Of course, you can't claim any rewards after you meet the playthrough requirements. To prevent players from taking advantage of promotions, casinos will often cap how much you can bet. There's also sometimes a limit on what you win when using bonus funds/spins.

Expiration Dates

Most 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. Slot games are usually 100%, while table games such as blackjack and roulette are between 5% and 50%. Some games do not contribute at all. 

If you enjoy playing table games like roulette, be sure to check out the best roulette casinos we recommend here at Casinos.com.

Ultimately, the golden rule is that you always 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 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 using 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
  • Make sure you make the minimum deposit required
  • Only use a real money promo code available in your state

Of course, a little research can go a long way in helping you find the bonus bonuses and promo codes. That's why we have an entire page full of information about casino bonuses. We urge you to visit this page and read through it so that you'll know what to expect!

Online Casino Promo Code Wagering Requirements

Have you been browsing online casino promo codes and their related bonuses? If so, you'll have seen the term “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 and online slot sites have different wagering requirements. The playthrough commitment will change from casino to casino and even from bonus to bonus. 

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, 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. 

A wagering requirement over 40x is starting to get high, while anything under 30x is pretty standard. More importantly, the wagering requirement must be realistic, giving you a fair chance of making the most of the bonus.
