An online casino welcome bonus is applied to your very first deposit at most gambling sites. A common version is a bonus that doubles your first deposit amount, with or without additional free spins in selected games. A lot of these offers are similar but throw an eye on the terms & conditions as they tend to vary more. All of the best casino welcome bonuses in the US are listed on this page. 

Why Claim a Welcome Bonus?

✅ Extra funds for online gambling

✅ Extended gambling sessions

✅ More value for what you spend

Online casinos with free signup bonuses are ideal if you want to try out a new site without having to spend a cent. These bonuses are typically smaller than any casino deposit bonus and come with attached T&Cs like all other offers. However, they’re completely free, and you even have a chance to win with it.

A no deposit bonus is essentially risk-free — you get to experience the casino and gamble without any of the stress! It doesn't get much better than that. The main downside, however, is that no deposit bonus casino sites are becoming rarer these days.

You can often instantly qualify for an online casino bonus. But this isn’t always the case, as you may have to provide a promo code. They’re used as a promotional tool by US online casinos to attract new players and retain them.

Wouldn’t you like to know about the codes you use? You never want to miss out a bonus that rewards you with extra funds. Otherwise, you won’t have the opportunity to maximize your bankroll.

With free spins, the concept is pretty simple. The casino rewards you with spins that you can use to play designated slot games. You don’t have to spend any extra money for those spins — they’ll be credited to your account!

Of course, free spins are available as standalone promotions. However, they’re a lot more common as an additional reward with other bonuses. For example, welcome bonuses will include free spins to entice more players to sign up. 

Why Claim Free Spins?

✅ Low risk but with real money wagers

Even if luck isn’t on your side, you’ll still get something in return. Cashback bonuses represent a percentage of the money you lose, given back to you by the casino. This way, you can mitigate your risk and gamble a little more freely. 

Is a cashback casino even worth joining? In our opinion, it certainly is because you never want to leave any money on the table. Cashback bonuses are very beneficial because you’re preserving the long-term value of your bankroll. 

Why Claim a Cashback Bonus?

✅ Real money losses aren't as harsh 

✅ Protection of your bankroll over time

✅ Winnning something even when you lose

It’s very common among US players to seek out bonuses that offer 120 free spins. The rules aren’t very complicated — you’ll become eligible and claim your reward. Furthermore, 120 free spins are considered to be a very generous amount. 

Unfortunately, you won’t discover many casino bonuses that include exactly 120 free spins. However, this doesn’t mean that you can’t claim the specified amount. You’ll also discover other promotions that offer you free extended gameplay. 

Why Claim 120 Free Spins?

200 appears to be the magic for many online casino players. The 200 free spins package is very popular, sought after by slot enthusiasts around the US. This is a bonus involving free spins, of course, and sometimes a deposit isn’t necessary to claim them. 

Again, 200 is a specific number. Many US online casinos offer free spin but in increments that often vary from each other. The good news is that you can combine multiple bonuses to cross the 200 free spin threshold.

There are as many types of bonuses out there as there are casino operators. What's more, these promotional offers change all the time. Depending on your gambling style and budget, one might be a better fit than another. 

Of course, you can't claim these bonuses if don't know where they're available. That's why we'd like to break down the best online casinos that offer a variety of bonuses. 

Online casinos are only legal in six US states: New Jersey, Pennsylvania, Delaware, West Virginia, Michigan, and Connecticut. While you don’t have to be a resident there, you must be located in the state when playing. Geolocation software will determine if you are, whichever device you're on. Any play outside these states is illegal, other than sweepstakes-style casinos. 

Once you’re in a legal US state, you can take advantage of bonus offers. To get the best online casino deals and the most out of your experience, we recommend that you browse through the sites that are available in regulated states so that you can get an overview of the offers available.

Here is a more detailed rundown of where you can play legally and find casino welcome bonuses in the US.

Online casino bonuses are an incentive for players to sign up and keep betting. When bonus offers can boost your bankroll without driving to a land-based casino, it's more of a reason to wager online and play real money slots.

Casinos also use bonuses to get a leg up on the competition. Some operators undercut playthrough and deposit requirements to generate loyal users. Others go all in on a flashy welcome bonus to attract new players. At the end of the day, everyone wants to turn a profit. If an online casino offers bonuses with a fair house edge and wager requirements, it's a win-win.

Most casino bonuses are calculated based on a percentage of your initial deposit. This number typically ranges from 50-200%. This is the portion of the deposit amount you are eligible to receive as bonus cash. The bonus is usually capped at a certain amount; you’ll see 1,000 dollars often being the max amount for a bonus offer. 

Say you’re making a deposit of $1,000 and get a bonus of 100%. You then have a total of $2,000 in your player account. The bonus works just like regular cash, but of course, come with terms and conditions that could be of great importance. I’ve therefore broken down the things you want to check out before you make use of a bonus offer.

Once you find a casino bonus that fits your preferences, here is how to take advantage of the offer:

1. Review the T&C – Pay attention to the bonus terms and conditions. Check out the wagering requirements, minimum deposit, eligible games and payment methods and the expiry date.
2. Create an account - You will be required to fill out the registration form with information like name, age, address, phone number and such. This usually only takes a couple of minutes.
3. Make a deposit – Go to the sites cashier and make the required deposit to claim the offer, or more if you wish. If you’ve found one that doesn’t require a deposit, the bonus should already be in your account.

Most bonus offers come with wagering requirements, also called playthrough requirements. These conditions dictate the number of times you have to bet a bonus before you can withdraw funds. Wagering requirements are generally between 30 and 50, depending on the site and bonus type.

For example, let's say you get 100% of your first deposit up to $1,000. This bonus carries a 30x wagering requirement. You have to bet $1,000 x 30 ($30,000) to withdraw cashable bonuses. In short, look out for offers with the lowest wagering requirements!

How to Beat Wagering Requirements:

• Choose online casino bonuses with a low playthrough
• Play games with high contribution rates
• Boost cash funds early with high volatility games
• Stabilize bankroll with low volatility slots

The latest casino bonuses and free spins are often found on the “Promotions”-page at any given casino, so keep an eye out there as you won’t necessarily find it all in your inbox. Some of the most typical offers you’ll find are:

Reload Bonuses

A reload bonus usually follows the initial casino sign-up bonus. It essentially acts as a deposit bonus for existing players. It’s definitely nice to have if you play often. Most reload bonuses match 25-50% of a deposit up to a certain amount. Some are only rewarded for specific payment methods. If you’re interested in reload bonuses, you're in luck as most casinos listed here offer them!

Cashback Bonuses

Cashback bonuses are usually offered after you’ve played for at least a week at sites that offer them. Bonus terms always vary, but a rule of thumb is that you have to play for a certain amount one week to receive a percentage of your losses back the following week.

High Roller Bonuses

Players sporting heftier bankrolls will gain access to high roller casino bonuses through VIP-programs. These bonus offers tend to be more generous and sometimes with considerably lower wagering requirements. There are usually 5 VIP levels that offer a bigger slice of the action as you progress.

Mobile Casino Bonus

Sometimes you’ll find offers specifically for mobile use, although the best online casino bonuses are available on all devices. Mobile casinos may not offer all the games you want, but you can place bets and cash in chips on the go without missing a beat. There are also casino apps by various operators that can make things easier if you log in frequently.

It can be tricky for players to sort through every casino bonus online. How do you know which ones offer you the most value? Each bonus is different, and you may not know what you’re getting until you begin gambling. 

The good news is that we have a flawless rating system that involves casino bonuses. We look at several key factors to differentiate the best from the worst:

Deposit Match and Amount

Online casinos often match a percentage of your first deposit. At most legal gambling sites, it’s usually 100% of your first payment, which is pretty fair. However, the percentage can also vary depending on the casino operator. 

Of course, the deposit match also covers a certain amount of money. Our job is to determine how much every gambling operator is willing to cover. In some instances, you can claim as much as $2,500 in extra funds. A bonus like this will often appeal to high rollovers. 

Rollover Requirements

Every player must bet the amount of their deposit a certain number of times. This is known as a rollover requirement, and it’s meant to prevent fraud/bonus abuse. We always check to see if the playthrough is manageable for every casino player. 

Gaming Eligibility

Now what’s the point of claiming a bonus if you can’t use it? Every online casino limits your eligibility to certain games. We tend to favor any bonus that gives you more freedom to explore the overall gaming selection.
