Exclusive US Casino Bonus Codes

We are always on the lookout for casino bonus codes that lead to valuable promotions. We also understand that these codes are only temporary, so we continually check for fresh ones that can unlock new offers. Once we find them and test them to see if everything works as advertised, we promptly update this page with the latest information.

Below are a couple of tables that contain the best casino bonus codes you can enter at top online casinos and sweepstakes platforms across the US.

Free Casino Bonus Codes for Existing Customers

In 99% of cases, casino bonus codes are used to unlock some of the best casino bonuses, most of them being a welcome bonus. They are often entered upon registration or while completing your first deposit or purchase. 

However, on some rare occasions, a casino bonus code may be applied to an offer designed for existing customers. For instance, a casino may present a special holiday bonus during Christmas or Valentine's Day, but only for those players who have it.

If we ever run into a casino bonus code leading to an ongoing promotion, you will find it right here.

How to Use a Casino Bonus Code: Step-by-Step

A casino bonus code is a special alphanumeric string entered to unlock a specific promotion. Here is how to use one:

1. Find a Valid Bonus Code Locate the code you want to use. You can find these on the casino's official promotions page or on trusted review sites like WSN, which often host exclusive offers. Be sure to copy the code exactly as it appears.

2. Locate the Code Field Depending on the type of offer, you will need to enter the code in one of two places. For welcome bonuses, look for a "Promo Code" field while filling out the sign-up form. For reload offers, you will usually find the field on the cashier's "Deposit" page before you confirm your payment.

3. Enter the Code to Opt In Type or paste the code into the designated box. This step acts as your "opt-in," telling the casino exactly which promotion you wish to claim if they are running multiple offers simultaneously.

4. Make a Qualifying Deposit Most codes require a deposit to trigger the offer. Complete your transaction, and once it is processed, the bonus funds or free spins should be automatically credited to your account.

Types of Casino Bonus Codes

Casino bonus codes can unlock a variety of casino promotions, including but not limited to:

• No deposit bonuses: By applying the right code, you can get bonus cash, coins, or free spin bonuses just by signing up without committing any of your own money. Check the best no deposit casino bonuses in the US that you can claim today.

• First deposit bonuses: These typically match a player’s first deposit, like 100% up to $1,000, for example. They can also be a combination of a deposit match and free spins or can be spread across multiple deposits.

• Cashback offers: Instead of giving you the bonus funds right away, this promotion merely returns a percentage of your net losses during the promo period. While they are rarer than the others you can still find cashback casino bonuses in the US.

• Exclusive promotions: The right promo code may land you a special deal that is available only through a select partner like WSN.

• Holiday offers: These can be claimed during and around certain holidays like Christmas, Easter, the Fourth of July, Valentine’s Day, Halloween, and more.

Why Do Casinos Use Bonus Codes?

You might wonder why casino bonus codes are necessary in the first place. They serve a few key purposes beyond just unlocking a deal. Primarily, they act as a simple tool for player choice, allowing you to easily select the specific welcome offer you want if a casino provides more than one option.

Internally, these codes help the casino track performance, showing them which promotions are most popular with players. They are also vital for affiliate partnerships; when you use a code from a site like WSN, it signals to the casino that we referred you. This allows them to track the partnership and guarantees you receive the exact, tested offer we advertised.

How to Claim Bonus Codes for Online Casinos

To use a bonus code, you just need to find its associated bonus code casino, copy-paste or manually type in the code during registration, deposit, or while claiming the bonus, and you’re done.

Here’s a quick step-by-step guide that describes how using a casino promo code works:

1. Find a valid online casino promo code: To complete this first step, you just need to look at the list on this page. Our experts here at WSN curate and verify the best offers and share bonus codes that help you unlock them.

2. Register to a casino site: If you’re a new player, you’ll need to create an account. This often requires you to share your email, name, address, phone number, and other personal details. You also must be of legal age and from an eligible state.

3. Enter the bonus code: The registration form will often contain a field where you can paste or manually enter the promo code. Some casinos require codes later on during deposit or bonus activation.

4. Start playing: Once the bonus funds have been credited to your account, you can explore the casino’s games and start playing.

5. Meet the requirements: Most bonuses come with wagering requirements, game restrictions, and expiration dates. Always check the bonus terms to understand how to unlock your winnings.

Casino Sites That You Should Avoid

Not all online casinos that claim to be US-friendly are actually licensed and regulated. Some run without proper oversight, use unfair terms, or make withdrawals almost impossible. Even offshore casinos dangle tempting promo code offers to lure players in, only to trap them with hidden restrictions and shady practices. If you ever come across a casino bonus code that seems too good to be true, always double-check that the casino is legitimate.

There are too many casinos you should avoid to even count, so I’ll only highlight a few. Also, if you suspect a casino may be fraudulent, please feel free to report it to us so we can add it to our blacklist casino list.

The following three you should definitely avoid:

1. Slots Empire - This site has a history of unresponsive customer support, frequent payout issues, and very low withdrawal limits that make it hard for players to access their winnings.

2. Manhattan Slots - Associated with the notorious AffPower Group, this casino has received plenty of player complaints and enforces low cashout limits that can frustrate even casual users.

3. Raging Bull - Known for slow payouts and poor customer support, Raging Bull also has extremely high minimum deposit and withdrawal requirements that make it an impractical choice for most players.

Every relevant factor goes into our evaluations, from bonus value to game variety, our user experience, banking, and customer care. Once everything is checked, we give the casino a final grade and rank it accordingly.

Our work is never done, as we also spend several hours each week checking whether the bonuses are still active or if any new ones were added, ensuring that the list before you is always up to date.

• Limit your playing time: Legit online casinos have handy, responsible gambling tools you can use to keep gambling from taking over your daily routine. These include time, deposit, and loss limits, as well as temporary and permanent account closures.
