What are casino bonus codes?  

Some online gambling sites require casino bonus codes to access new player offers or existing player promotions. Promo codes will help you navigate the offers at sites that offer numerous bonuses, whether they are free spins, a crypto bonus, or a first deposit match.  

When you enter the relevant bonus codes for casinos, you’ll gain instant access to the bonus funds or spins, which you can then use to play top-rated games. 

Do you need bonus codes for casinos?  

This just depends on the casino online site. Some require you to enter a bonus code, while others don’t. In researching the best bonus casinos, we found that most online casinos don’t require a promo code. In these cases, when you create an account and make at least the minimum deposit, the bonus funds will be automatically added.  

Where online casino bonus codes are required, they are listed explicitly on promotional material from the casino itself. You can also find details of the welcome bonus promo code listed on the offer’s terms and conditions. In other words, these codes aren’t difficult to find if required.

While checking for bonus codes for casinos, you can also look at the other essential terms and conditions. This will give you all the information about the promotion and explain how and when to access the relevant casino deposit bonus codes.  

How to access casino bonuses with promo codes  

When researching bonus codes for casinos, we found that most welcome bonuses and ongoing online casino promotions were available without casino promo codes. Most promotions are triggered by a minimum deposit or opting in rather than needing a specific code.  

That said, a handful of online casinos require special codes to access casino bonuses, so it helps to know how to enter them if you sign up for one of these sites. Typically, there are three ways to access bonuses with casino promo codes:  

When you create an account  

Some online casinos ask you to enter a bonus code when you create your account to activate an offer. This is most likely the case with no-deposit bonuses, activated when you sign up and don’t require a real money deposit. When following the sign-up prompts, you’ll see a box for entering the promo code, and as soon as you confirm your account, the no-deposit bonus is added to your account balance.  

When you make your first deposit  

At other casinos, you must enter the bonus code when you make your first deposit. You can do this after creating your account and spending some time on the site. Navigate to the casino’s cashier page, which you can find under the “Payments” or “Banking” tab, choose a deposit method, decide how much to add, and enter the promo code in the relevant box. If you’re eligible for the promotion, the bonus funds or spins will be immediately added to your account. 

When you make a subsequent deposit  

As a current casino customer, you might be sent promo codes to your email address or via SMS. Alternatively, you might see them listed under the site’s “Promotions” tab when looking for the latest offers. Casino promo codes for existing customers are typically for reload bonuses, which are triggered when you make your next deposit. So, head to the cashier and deposit on the relevant day with the promo code to pick up your reload bonus.  

Different types of casino promo codes  

Online casino bonus codes can be used to access different promotions. Some are exclusively available to new players, but casino promo codes exist for existing customers. Here are the different types of promotions that the current bonus code might trigger at an online gambling site:  

Deposit match promo codes

One of the most prevalent offers at online casinos for new players is the deposit match. Here, the casino offers to match 100% of your initial deposit up to a specific amount, perhaps €100 or even €1,000. To access the deposit match, you must enter the promo code when signing up or as you make your first deposit, depending on the casino’s terms and conditions. Remember, you only get one chance to make a first deposit, so don’t forget to enter the promo code!  

Free spins  

You might also come across free spins promotions triggered by a casino promo code. Free spins might be available for new customers or existing players, depending on the promotion. If they’re available as part of the welcome package, you’ll need to enter the promo code when creating an account or when you make a deposit. Free spins typically add 50 or 100 spins to your account when you make a minimum deposit of €10. 

Cashback  

A casino’s cashback promotion might also need a special promo code. Here, the casino offers to refund a percentage of your losses up to a specific amount within a given time frame. For example, if you deposit and play with between €20 and €100, the casino might return 30% of your casino losses within your first 48 hours of play. In this case, you must enter the promo code when creating your account so the cashback offer is triggered immediately. 

No-deposit bonus codes

One of the best ways to get started at an online casino is with a no-deposit bonus. As the name suggests, the casino offers bonus cash without requesting a deposit in return. In other words, you can play casino games for real money without risking your own cash. Though no-deposit bonuses are available for relatively small amounts, they’re a great way to kick things off. To use casino bonus codes for no-deposit offers, you must create an account and enter the promo code when prompted. The bonus cash will then be immediately added to your account. 

Reload bonuses  

While many casino bonus codes are for new customers, some bonus codes for casinos are specifically for existing players. If you head to the casino’s “Promotions” tab, you’ll find details of the relevant offer and any required bonus codes, which activate reload bonuses on specific days. For example, if you deposit funds on a Monday with a specific casino promo code, you might be eligible for a deposit match bonus of up to €100.  

How to activate promo codes at the best bonus casinos  

If you require an online casino bonus code to access the site’s promotions, here are the steps you need to follow to get started with a bankroll boost:  

1. Create an account: Head to the casino’s homepage and click the “Sign Up” or “Register” button. Then, follow the prompts, provide details, and create your account. If you’re accessing a no-deposit bonus, enter the promo code when creating your account.  

2. Check for a bonus code: Before making your first deposit, check the terms and conditions of the casino’s bonus to see if you need to enter a code. If no code is required, you might need to “opt-in” for the bonus, which means you need to check a box. You should also check for any other actions, such as the minimum deposit required and how long you have to make the initial deposit.  

3. Deposit funds and enter the code: Choose one of the secure payment methods and make at least the minimum deposit to trigger the bonus. When prompted, enter the online casino bonus code in the box provided.  

4. Play games: Check that the bonus funds or spins have been added to your account and play participating games.  

5. Satisfy the wagering requirements: If you win while playing with bonus funds, you must satisfy the wagering requirements before cashing out. 

Gamble responsibly when playing with bonus funds  

Responsible gambling is crucial to your enjoyment while playing at the best bonus casinos. You should always bet within your means, even when playing with bonus funds or free spins. Central to this is setting your limits and ensuring you don’t spend more than you can afford to lose. You can also visit the casino’s safer gambling portal for tips and tools to help you stay in control.  

Where can you find casino promo codes for existing customers?  

Though many casino promo codes are marketed to new customers, existing customers may also need them to access ongoing promotions. In this case, casino promo codes for existing customers can usually be found under the “Promotions” tab on the casino website. Email the customer support team for further assistance if you can’t find the relevant code. 

Are there any casino bonus codes for no-deposit promotions?  

At some of the top online casinos in the US, in particular, you can enter a specific promo code to access a no-deposit bonus before making your first deposit. Details of this code can be found within the casino’s promotional terms and conditions, so read through the offer details before signing up.  

Which are the best bonus casinos?  

BetMGM, BetRivers, and Borgata are rated as the best bonus casinos, offering outstanding promotions, great value, and game variety. Check our top list of casinos to get started at any of the best bonus casinos, and take note of any promo codes you need to access the welcome package. 

Do you need a promo code for deposit match bonuses?  

Sometimes. If you need to enter a promo code to access a deposit match bonus as a new customer, the casino will list the bonus code underneath the main banner on the website or the “Promotions” page. You should always read through the terms and conditions before making your first deposit so you don’t miss out on any key actions you need to take to trigger the bonus.  

Is there a promo code for free spins promotions at online casinos?  

Some casinos might require a promotional code for free spins offers. Whether available to new customers or existing players, some promotions require you to enter a code to access them. This is particularly true if the online casino runs multiple offers simultaneously, letting you specify which offer you want to access.
