The list is updated regularly to ensure it reflects the most current casino bonus offers in the US. So far, it looks like online casinos don’t change their bonus offers too often. The bonus ranked number one may not be the best fit for absolutely everyone, but it’s definitely the best one-size-fits-all casino bonus available in the US today. If you’re looking for something more specific, check out the category winners below.

Best Casino Bonus by Category

Welcome bonuses take many shapes and sizes. This is a fairer assessment compared to the top list as it singles out the best bonus in its category. Whether it’s free spins you’re after, or a no deposit bonus, US online casinos cover everything.

All of these target different players’ needs and wants. You can find all these available to new players, except for the tournaments and daily offers. To take part in them, you’ll either need to skip the welcome bonus, or wait until you’re done with the wagering requirements.

Casino Bonuses to Avoid

As with online casinos in general, there are some kinds of casino bonuses you should avoid. While most of these should be avoided because of legal issues, there are also legal casinos that simply offer bonuses with unreasonable wagering requirements.

If the bonus terms aren’t publicly displayed, you should start asking more questions. Rogue casinos are known to change terms and conditions very often and enforce them retroactively. They do this with the casino welcome bonuses as well, which can end up costing you.

How to Find the Best Casino Bonus for You?

The longer the criteria list, the better verdict you can make on which online casino bonus is the right one for you. You can come across a bonus that’s good, but that doesn’t mean it’s necessarily what you’re looking for. Here’s a step-by-step approach to finding the best casino bonus.

1
choose game and budget
Step 1

Identify the type of game you want to play and set a budget

2
check licenses us
Step 2

Make sure the online casino is licensed in the US

3
check porcentages and amounts
Step 3

Look for the highest bonus percentage and the highest maximum bonus amount

4
check bonus terms
Step 4

Check the bonus terms in detail. WR, limits, expiration period, game restrictions. Anything that’s relevant to you.

5
choose bonus
Step 5

Do this with every potential bonus until only one or a couple are left. You will get what you’re signing up for!

You don’t need to follow the above steps in this particular order. However, these steps will help you eliminate most bonuses that don’t fit your needs.

You should be very careful when picking online casino bonuses since there are still lots of shady casinos out there. Take your time, read the full T&Cs and don’t get carried away with flashy offers. This especially goes if you are looking for a bonus that enables you to play table and card games because legal online casinos in the US still offer only a handful of those promotions.

How to Claim a Casino Bonus

Once you have found your ideal casino welcome bonus, there’s one last thing left to do: claim it! It isn’t a complicated process, but we’ve broken it down into simple steps for you.

How do I claim a casino bonus?

  1. Register with a legal US online casino
  2. Go to the cashier and opt-in for the welcome bonus
  3. Use a casino bonus code if one is required
  4. Make sure you deposit at least the minimum required amount
  5. Upon depositing, the bonus money is added to your account balance
  6. You can now start playing for real money

After you deposit, some casinos may require you to play with your money before you can access your bonus funds.

Enabling players to claim bonuses easily is casino operators’ biggest challenge. New players find them confusing, and experienced ones are usually very picky when it comes to bonus terms. Operators have pushed the boundaries and have improved the user experience in this regard. However, casino bonus codes, to this day, are a highly effective way of offering and claiming online casino bonuses.

What Are Casino Bonus Codes?

Casino bonus codes are a mechanism that allows online casinos to offer a specific offer to hundreds of players, without the players having to follow a specific link or a landing page. Players should use the bonus code during registration or when making their first qualifying deposit.

There’s no difference between a casino bonus that you get with the use of a bonus code and one that doesn’t use a code. Instead of bonus code, some casinos use the term “coupon code” or “promo code”. They all mean the same thing, these are just different naming conventions.

Pros & Cons of Casino Bonuses

Online casinos bonuses exist solely to attract new casino players or to reactivate and re-engage existing ones. Whether you’re one or the other, the following advantages and disadvantages likely apply:

Pros
  • Extended play time
  • Higher chances to win
  • They are an opportunity
  • More games to try out
  • Widely available
Cons
  • Wagering requirements
  • They lock in your cash
  • Game restrictions

Some of the pros and cons don’t apply to all types of casino bonuses. They are all bundled together, meaning our evaluation takes into account casino bonuses in general, not any specific bonus type.

Types of Casino Bonus Offers

Depending on the nature of the casino bonus, who can claim it, when, how many times, and why, there are quite a lot of different types of casino bonuses. However, what you get at the end can be put into three different categories.

The following types of casino bonuses are also available, though are much less common, and aren’t considered categories in and of themselves:

  • Casino tournaments – some tournaments require a deposit as a buy-in fee. Some casinos charge a buy-in fee. Either way, tournaments allow players to win prizes from prize pools that go well into 5 and even 6 digits.
  • VIP loyalty rewards – casinos thank their most loyal patrons by handing out a variety of rewards, cash prizes, exclusive bonuses, all-expense trips and other special privileges. Some of the perks go beyond the online offer and take you to land-based casinos in places like Las Vegas and Atlantic City.
  • Cash drops – Sometimes, all it takes is clicking “Enroll”, and you don’t have to do anything else. Whether it’s a perfectly timed deposit, or you’ve joined the casino at the right time, you can win cash simply by being part of the casino community. You need be an active player to be eligible for cash drops.
  • Reload bonuses – the equivalent of the sign-up casino bonus is the reload bonus, but for already registered patrons. You can usually find these in casinos’ “Promotions” section, or in your account dashboard. While similar, the wagering requirements are known to be radically different, including some winnings limits, and a condition that prevents you from claiming bonuses on every deposit, meaning you need to make a few deposits between casino bonus offers.
  • Free play bonuses – this is a mix of free spins and bonus money because you play with the “free play” credits, and whatever you win is converted to bonus money which you then need to complete WR on. Upon completion, you can potentially win and withdraw real money. This type of casino bonuses is extremely rare. It’s worth reading the bonus terms to ensure you’re on the same page.

All online casino bonus offers have two sides, external and internal factors. The former you can identify easily, the bonus percentage and the maximum bonus amount. The latter is what we call small print, the fine detail.

How Do Online Casino Bonuses Work?

Casino bonuses have one purpose: growing the player base. Bonus offers have become an integral part of every online casino, so much so that one without casino promotions and bonus offers would likely go out of business pretty quickly.

Here are two specific examples. The one on the left shows the national averages for casino bonuses, and on the right, you can see the best casino bonus in the US right now.

The US gaming market is pretty homogenous. Casino bonuses are well-balanced, and you can claim any of the offers above, or even all of them. Remember, though, every bonus has wagering requirements and other bonus conditions to meet before they can be redeemed.

Understanding what each of these terms means, and how they affect the quality of casino bonuses is vital to making sure you have a great bonus experience.

How to Calculate Your Bonus

Understanding what you’re getting out of the bonus offer sets the expectations for the bonus terms. Online casino operators have been known to use subtle tricks to make their offers look a lot more attractive than they really are.

If you’re dealing with a bonus offer advertised as “200% Deposit Bonus up to $1,000”, thenthis means that you’re better of capping your first deposit at $500, as anything above that doesn’t count towards the bonus amount.

However, despite it being a 200% bonus (i.e. double what most US online casinos offer), this comes at a steep price. When bonus percentages are this high, they almost always come with more difficult wagering requirements.

For example, this bonus has a WR of 10x the bonus amount. Your qualifying deposit is $500, but the bonus amount is $1,000. In practice, you’d need to wager $10,000 before being allowed to withdraw any of your winnings.

If you don’t have that kind of budget to spend on online casinos, then you’ll either need to aim for a much smaller bonus amount, or find a different online casino with more reasonable bonus wagering requirements.

Bonus Wagering Requirements Explained

Wagering requirements (WR) are the key bonus term that defines whether a bonus is worth your time. These require players to “rollover” an amount in order to “redeem” their bonus funds and make them withdrawable.

The WR amount is usually determined by the bonus amount, or by the sum of the deposit and the bonus amount. The former is definitely more favorable, whereas the latter pushes away most experienced players. Nevertheless, it all comes down to what the actual multiplier is.

Here are the usual wagering requirements for different online casino bonuses at legal operators in the US:

Wagering requirements
Deposit bonus WR

5x – 30x bonus (deposit + bonus)

Free spins bonus WR

1x – 5x bonus (free spins winnings)

No deposit bonus WR

1x – 30x bonus

Daily/weekly bonuses WR

1x – 20x bonus (deposit + bonus)

These ranges show you what you can expect from online casino bonuses in the US. It doesn’t make any sense to go for a casino bonus that’s not within these ranges.

The lower the WR, the better the bonus offer is. We always recommend selecting bonuses that will give you bang for your buck without too much effort involved. And remember: always check for the WR before committing!

How to calculate the wagering requirement?

The wagering requirement calculation is straightforward. All you need is the

  • bonus amount
  • number of times you need to wager the said amount
  • if you need to wager the bonus only, or both the deposit and the deposit amount.

For the time being, most bonuses at US casinos only require players to rollover the bonus amount only. Considering how new the online casino industry is in the US, though, this could change at some point.

Bonus amount: $100
Wagering requirement: 5x deposit + bonus amount
Amount to wager to release funds: ($100 + $100) x 5 = $200 x 5 = $1,000

Bonus amount: $20
Wagering requirement: 10x bonus
Amount to wager to release funds: $20 x 10 = $200

These two examples give you an idea of how wagering requirements work in practice. We don’t recommend committing to any bonuses that will force you to go over budget on your monthly bankroll.

Contribution Rates

If the WR sets the pace, the casino game contributions set the tone of the offer. As a casino bonus player, it’s important to make sure that you’re not spending any more than you need to. In some cases, casinos even limit players to just a few specific titles.

The most important thing to know is that different types of games contribute different percentages to your wagering requirements. 100% of what you stake on slots contributes to meeting the WR, but table games often have far lower values. In some casinos, as little as 20% of your bets on table games contribute to WR, while others don’t take those games into consideration at all.

The big, well-established online casinos offer more options to bonus players. They are the ones that allow bonus players to complete the WR playing roulette, blackjack, and in some cases live dealer games. Even though reading the terms and conditions is dull, we still strongly recommend going through all the details.

Clearly, a bonus that carries WR that can be completed by playing a wide array of games is better than one that limits you to just playing slots.

Game Restrictions

This is actually one of the easier terms to understand. There are games that casinos don’t allow players to use bonus funds on.

In general, live dealer games are usually set to real money play only. However, there’s a small number of operators, like BetMGM Casino, that allow even bonus funds to be used on live casino games.

Progressive jackpot slots are also usually kept out of reach of casino bonus players. This is done to avoid a huge jackpot being won by a player who hasn’t put their own money into the pot. Network progressive jackpot slots are restricted 99% of the time. In reality, there’s no cash transaction, and the casino technically has to transfer the jackpot fee to the game provider.

Expiration Period

All casino bonuses come with an expiration time. Casino welcome bonuses are available for a limited period, from the moment you open the casino account. Ideally, you claim all and any bonuses the moment you sign up with the online casino. This is the only way you don’t miss out on any casino promotions.

Expected expiration times
Casino deposit bonus

14 to 30 days

Free spins

3 to 7 days

No deposit bonus

3 to 14 days

Reload bonus

14 to 30 days

Other promotions

7 to 30 days

Except for limited time promotions, most others are available between 14 and 30 days. This way, the casino operator can predict potential cash flow disruptions, ensuring they stay solvent even if all their new players are winners.

Winnings Limits

The US gaming market is still growing, and as such, winnings limits are not a concern, yet. Considering other gaming markets, it’s only a matter of time before online casinos start imposing winnings limits on the extremely generous casino bonuses that easily reach four digit amounts.

Winnings limits allow online casinos to offer highly attractive bonuses with high maximum bonus amounts, yet they prevent players from winning big.

Something that you should prepare about, hopefully not soon, are winnings limits that are in the range of 2x to 5x the deposit amount, or up to 10x the bonus amount.

Tips to Complete Casino Bonus WR and Win Real Money

Contrary to popular belief, there are some ways you can increase your chances of successfully completing online casino bonus wagering requirements.

  • Play high RTP games – based purely on numbers, playing slots and other types of games with high RTP increases your odds of winning in the long run. Then again, if you play any casino game long enough, you will run out. Ignore any games that are rated to have an RTP under 96.00%.
  • Play low variance slots – variance determines the frequency of wins. Low variance slots come with frequent low wins. Triggering a bonus game usually makes up for the difference from bet to prize. This is the secret recipe to success of experienced casino bonus players.
  • Don’t switch between games too often – it’s a myth, but one that tends to work in players’ favor. Some players stick to only a handful of high RTP, low variance games for wagering requirement purposes.
  • Finish the WR as soon as possible – the expiration time is there to allow the operator to have some control over risk involved and volatility. It’s best if you complete the WR as soon as possible. Failing to do so voids all winnings. The fastest way to finish the WR is to play slots that contribute 100% of the bet amount or play blackjack and roulette with slightly higher bets.
  • Use correct information when you register – if any of the information you provide a casino is false when registering your account, then you’d be in breach of the casino’s terms and conditions (and even in the law, in some states). When you make a withdrawal request, the operator can deny payment on the grounds of using false information. This voids the bonus, and your account will likely get closed.

New Online Casino Bonuses

The only thing limiting the number of sign-up casino bonuses you can claim is the number of online casinos you sign up with. Beyond the welcome bonuses, you can take part in casino promotions that are available to registered players.

The type of offers you should be on the lookout for are as follows:

  • Reload bonuses (recurring bonus offers)
  • Casino tournaments
  • Loyalty rewards (in all shapes and sizes)
  • Daily bonus deals (available on a specific day)
  • Weekly bonus deals (available during a specific week)
  • Featured free spins (usually promoting a new slot release)

We strive to review every legal and licensed online casino as soon as they launch, and we make efforts to keep all of the bonuses on this page updated.

Why You Should Play with Casino Bonuses

Online casino bonuses win the popular vote. They are widely available, because all casino players want them, use them, and enjoy them. However, they’re only worthwhile if you can come to terms with the cons that come with them.

Here’s a more balanced look, for anyone who’s still on the fence:

Pros
  • More play time
  • More chances to win
  • More casino games to explore
  • Some are free casino bonuses
Cons
  • They tie your cash to the bonus
  • Wagering requirements
  • Game restrictions

As long as you’re not into a specific game that could potentially be restricted, or you don’t like the idea of wagering requirements, we recommend claiming every online casino bonus offer you can.

FAQs

At the moment, Golden Nugget Casino has the best welcome bonus in the US. It’s a match bonus up to $1,000 with 200 free spins on top, which you can use on 88 Fortunes Megaways slot by Scientific Games. The bonus varies by state, yet considering the options it brings to the table, it should be your top choice. If you are looking for alternatives, BetMGM Casino can deliver a similar experience.

There are welcome bonuses and bonuses that are available to already registered players. To claim welcome bonuses, all you need to do is open a casino player account and make a qualifying deposit. There are no deposit bonuses that are available immediately upon signing up, and no deposit is required.

New players should prioritize bonuses with simpler bonus terms and conditions. Alternatively, you can select one of the welcome bonuses displayed in our top list. BetMGM Casino’s welcome bonus is considered a generous new player bonus with straightforward bonus terms. It also allows players to enjoy a wide array of casino games.

An online casino welcome bonus is an incentive given to newly registered players. In most cases, it’s a match bonus with favorable wagering requirements and few game restrictions. Casino players can only ONE welcome bonus per operator. Crossing the state borders and attempting to sign up from a different location does not make you eligible for another new player bonus with the same casino.

Online casinos offer bonuses and promotions to attract new players and reactivate ones that are already registered but haven’t played any casino games in some time. In short, they are incentives to grow and maintain the player base. All casino bonuses and promotions are subject to bonus terms that protect the operator’s interest and preventing them from going insolvent.

At the moment, free spins for new players are rare in the whole of US. This applies to legal online casinos. The only online casino that offers free spins as part of their welcome package is Golden Nugget. In our experience, it’s only a matter of time until other operators see the positive effects of offering more free spins. However, there are much more US casino sites that offer free spins to registered players.
