US Online Casino Bonuses

When you join a new online casino, they should always give you something free; whether it is a free spin, no deposit bonus, or the first deposit bonus. BonusSeeker strives to be your "Home of the Bonus Code" where you can find the best free no deposit sign up bonus available at legal online casinos using our navigation menus to see what is available in your state.

When it comes to online casinos, no matter where they are, they will always offer bonuses of some kind. The most popular, and arguably the most important, is the welcome bonus.

Also known as the sign-up bonus, a welcome bonus is there to draw in players to an online casino and encourage them to open a new account and make a deposit. But that's not the only use it has. These promos serve to make the casino stand out from the crowd, making them more appealing to potential new players.

US online casino bonuses can be a range of different things but generally tend to be deposit match bonuses or free spin bonuses. Depending on the casino, welcome bonuses can offer vastly different things, so it's important for you to check out the various bonus options, scout out the different amounts you can get and see if there are any wagering requirements attached to the bonus payout.

How Do Online Casino Bonuses Work?

Online casino bonuses are relatively simple to figure out. After all, the casino wants to bring in new players and keep them, not confuse them! 

Casino bonuses follow two different types:

  • Deposit match bonuses
  • No deposit bonuses

They can be made up of matching deposited money, free cash or free spins. All you need to do is either input one of our listed bonus codes when prompted on sign up, or simply sign up for a new account via our link with no code required. 

The bonus will be added to your account immediately and can then be used on casino games right away.

PartyCasino in New Jersey, for instance, offers brand new players a no deposit bonus for simply signing up. This money gets added directly to your account and can be bet instantly. However, PartyCasino doesn't stop there. They also offer a first deposit bonus to newcomers. 

In order to get this promo, you need to make an initial minimum deposit of at least $10, which will be matched 100% by the casino thus giving you double the amount to play with. The bonus continues with a 100% match deposit on the second and third deposits, making this a pretty lucrative offer.

With this in mind, it’s a good idea to point out that just because one casino offers a higher match percentage, it doesn't mean it's a better bonus. You need to check the maximum amount the casino will be happy to match. For instance, a casino that offers a 100% match up to $200 is giving you more money than a casino offering a 400% match but only up to $25. So bear that in mind when checking out the different bonus options.

Online Casino Bonus Codes

Many online casinos require a bonus code for you to obtain your welcome offer. Some casinos require a two-step process like, for example, the Mohegan Sun Online Casino bonus:

STEP 1: Click the link directly on our page. Enter the code SEEKER when you sign up. Doing so will give you the Mohegan Sun no-deposit bonus.

STEP 2: Use bonus code SEEKER to receive your full first deposit bonus, a 100% match on your initial deposit.

You won't always need an online promo code, as not all casinos will use them, but if you do come across one you don’t want to miss out on using it. Some online casinos will simply automatically add the bonus to your account once you've finished signing up, but not all. 

Some will require a bonus code. This is actually better for most players as casinos will have a few different options available and you can guarantee you get the specific bonus you want.

If you want to make use of the bonus code, just copy and paste the code in when prompted during the signup process. The casino will then know that you want to accept their offer and will see that your account is credited accordingly. 

Bonus codes are particularly useful if the welcome bonus spans several deposits - they allow both you and the casino to keep track of what promos you have collected.

Online Casino No Deposit Bonus

One of the more popular US online casino bonuses is the no deposit bonus. This kind of promo is awarded to your account the moment you sign up and create a new account. Your no deposit bonus can be used immediately to play at the casino you’ve just joined. 

These cash bonuses can often be used on any game in the casino so you can try out a range of games you might not otherwise play. Of course, it's important to note that your no deposit bonus is not cash you can just withdraw right away. It will be in the form of casino bonus dollars, which have to be used on their online games and cannot simply be withdrawn once claimed. This is where the wagering requirements come in.

Why Should I Look For No Deposit Bonuses?

  • Your play with a no deposit bonus counts towards your VIP rewards
  • You can test out games and casinos before using your own money
  • The bonus can (mostly) be played on any game within the casino
  • Once your playthrough requirements are met any profit is yours

How To Claim A No Deposit Bonus

  • Choose a US online casino
  • Click on the signup button on our page and fill out the required information to create your account
  • If there is a bonus code prompt, input the code we have listed for the casino. Alternatively, simply tick the box for opting in for the promo
  • Confirm and verify your account
  • The no deposit bonus should already be in your account
  • Get betting!

Online Casino First Deposit Bonus

First deposit bonuses are possibly the most common welcome promo offered. First deposit bonuses require you to actually make an initial deposit at the casino but you will get that amount matched (or exceeded) by the casino. 

Usually, there is a minimum and maximum amount you can deposit to qualify for the bonus. Once your deposit has been made, the casino will then match this value by a pre-specified value. 

The most common match percentage is 100%, which means you get double the money you deposited  to play with. In some cases, though, the match can be lower eg. (25%) or as high as 400%. First deposit bonuses do require you to put a little money in to start but you do get a substantially larger bankroll to begin your play, which means you can test out a wider range of games you might not have tried.

Why Should I Look For First Deposit Bonuses?

  • Essentially free money to play with
  • You can test out a wide variety of games or choose your favorites
  • Access additional welcome bonuses if the first deposit bonus spans subsequent deposits
  • Often these bonuses have free spins attached

How To Claim A First Deposit Bonus

  • Click on one of our links at
  • Sign up to the casino you chose by inputting all the required information
  • Opt-in for the bonus either using the bonus code or ticking the required box if necessary (some first deposit bonuses do not need an opt-in but will be added automatically once the first deposit has been made)
  • Once the account is finalized and verified, head to the banking section of the casino
  • Choose your preferred payment method
  • Select the amount you'd like to deposit
  • Click submit
  • Deposits occur instantly so your account will be credited within minutes
  • Once the payment is verified, the casino will match the amount and add that value to your casino account
  • Time to get playing!

More Online Casino Bonuses

Ongoing online casino deposit bonuses work along very similar lines to a first deposit bonus, in that they match the amount of money you have just added to your account. The only difference here is that the promo isn't exclusively for new players.

Instead, this promo can be offered at any time to any player. For instance, an online casino may allow both new and old players to take advantage of their deposit bonus offer. However, when existing players make use of the promo, it's generally called a “reload” bonus. 

Often, though, the actual match value will be lower - sometimes just 50%, as you might already be comfortable and settled at the casino. This doesn't make it a worse promo though, as you're still getting some additional free money to use and potentially win with!

Online Casino Free Spins

Free spins can actually come under both the match deposit header as well as the no deposit bonus, depending on the casino.

Unlike a no deposit bonus that gives you free bonus cash to use on potentially any game (unless otherwise noted), some online casinos offer free slot spins as their no deposit bonus offer. Hard Rock Online Casino in New Jersey, for example, offers a free spins no deposit bonus (giving 500 free spins at signup).

It’s rare for casinos to offer free spins alone, with no strings attached, so generally free spins come as part of a match or first deposit bonus. This means that in order to get your hands on them, you will have to make the required deposit into the casino. Only then will you be awarded the spins into your account. 

Additionally, these free spins are usually attached to a specific game so you can't play them on any slot. While this may sound like a drawback, it does mean that you get to test out a game you might otherwise not try.

Free Spin Bonuses for Specific Slots or Games

As a general rule, game-specific bonuses tend to be free spins offered where the spins have to be played on the allocated game. Trying to use the free spins on another slot game will only result in failure if you have no credit in your account, or you will simply find that you have spent your actual cash in playing the game. 

Sometimes a US online casino offers welcome bonuses tailored for specific games. Other times, it’s for a specific casino game type. For instance:

The Borgata Online Casino no deposit bonus offer is only allowed for slots: 

"Only play on slots, classic slots or progressive slots count towards the wagering requirement for the $20 Bonus Slot Dollars."

In some cases, game-specific promos are also available when choosing a live casino or poker promo, but even these only tend to specify a genre rather than a single game within that group.

However, game-specific bonuses can be very handy as they offer a lot of practice on a specific casino game. 

What are Online Casino Cashback Bonuses?

Cash back bonuses at online gambling sites are like an insurance policy. The online casino will give you the money back if you lose your deposit, or a portion of it, during an initial play period. 

There’s no reason why you shouldn't take advantage of this kind of promo when it's offered as long as you are ready to meet the list of various requirements.

The average cashback bonus varies but you may find sites that offer it up to $50. The important terms and conditions include the fact players must be 21 or over to sign up and located in a state that offers online gambling. Additional conditions may include the fact it must be a first deposit, no less than a certain amount, and up to a maximum of $100.

What is a VIP Club Bonus?

USA online casinos show their appreciation to their players through loyalty clubs and VIP benefits. When you are part of one of these programs, you'll never have to worry about leaving the tables empty-handed.

Rewards programs usually have levels or tiers which you can climb by playing real money games and accumulating points for rewards. These awards include:

  • Special bonuses
  • Event tickets
  • Gifts
  • Discounts on hotel stays
  • Free spins and plays
  • Free real money cash bonuses

Advantages Of An Online Casino Signup Bonus

Grabbing an online casino bonus when it’s offered might seem like a no brainer, but there are still a surprisingly large number of people who avoid taking a promo when joining a casino. 

It could be that they are nervous about putting their own money in, or they don't feel they can meet the wagering requirements. Whatever the reason, some people avoid them. However, we generally think that saying yes to a casino promo is the way forward. Here are just a few of the reasons why you should take on an online casino welcome bonus:

  • Chance to check out the casino and the games it offers
  • Depending on the bonus, you get free money to play with
  • Even if you don't succeed in winning you’ve gained valuable experience
  • Taking one bonus can open you up to further bonuses offered by the casino down the line

Online Casino Bonus Codes vs. Promo Codes

Online casino bonus codes and online casino promo codes are really the same things. It comes down to what an online casino site decides to call it. Some online casinos in the US refer to the code as a “promo code” or a promotional code, while others refer to it as a “bonus code.”

No matter what it's called, the end goal is the same. You should use promo codes and bonus codes to qualify for offers that casinos might not otherwise give you. That's why it's critical to research and find the best promo and bonus codes for online casinos in the US. We at BonusSeeker do that for you so you don't have to waste your time.

Frequently Asked Questions

Can I claim and use an online casino bonus on my phone?

For the most part, yes you can use an online casino bonus on your casino app or gambling app. These days, online casinos make sure that all their features are available across all of their gaming platforms.

How do I cash out my online casino welcome bonus?

If you’re lucky enough to make some winnings on your welcome bonus, you might then be looking to cash it out. First though, you need to make sure you have fulfilled any of the wagering requirements otherwise you will not be able to make the withdrawal. If you've fulfilled these, then simply head to the banking section of the casino, select the amount you'd like to withdraw, choose your payment method and click confirm. See here for the online casinos with the fastest cash outs.

Are casino bonuses for new players only?

It depends on the type of bonus. Welcome bonuses are indeed for new players only and you will not be able to access them if you already have an account at that online casino. However, other promos such as loyalty or reload bonuses are available for you.

What Are Wagering or "Play Through" Requirements?

Wagering or playthrough requirements are a necessary part of online casino bonuses. What these are is a given figure for how many times you must bet your winnings before you can cash it out. For example, if you make $10 on a slot with a wagering requirement of 20x. This means that the $10 must be played through 20 times before it can be withdrawn. 

This will mean that you have to spend $200 at the casino - though this can be done simply by repeatedly playing the winnings you make rather than depositing any more money.

Many players are put off from taking a casino promo because of these wagering requirements, but don't be. These are here to protect both the player and casino from fraudulent activity. Without these requirements in place, online casinos really wouldn't be able to reward players with bonuses.

However, we still suggest checking out the wagering requirements attached to a bonus when you're looking at the different options. Generally, requirements tend to sit between 1-25x, which are decent enough and quite doable in terms of meeting them. 

On the high end is 50x, which is best avoided. In some cases, you'll get lucky and find a casino with no wagering requirements at all (snap that bonus up instantly), or one that offers a playthrough between 2-10x.

What is the Game Contribution Percentage?

When you accept a promo that has wagering requirements attached, you need to check out the game contribution percentage. This is important as not all game types and genres will contribute the same amount.

The contributing percentage is the amount that each type of game counts towards the final wagering requirement. Essentially you can view it as a multiplier: if the betting on a game is just 50%, you effectively need to wager double the amount to meet the same requirements.

If you like slots, the contributing percentage is generally a full 100%, so the wagering requirement stays at that level. Some games like live games or various table games may not even count at all towards the wagering requirements, which means you should avoid playing those games altogether when trying to fulfill these requirements. 

Things change depending on the game type and you can find this information by reading the terms and conditions of each online casino - something we can't emphasize that you do enough!

When checking out a new potential promo, you should be looking at the wagering requirements coupled with the contribution percentage and matching this to your game preferences before launching in and accepting a new bonus offer. After all, no matter how good a promo sounds, it still needs to be the best one for you!
