Types of Casino Bonuses and Rewards

Gambling sites will offer a number of online casino promotions for players. As standard, nearly every online casino will offer a welcome package. However, you’ll also find no deposit offers, free spins packages, and bonuses for existing players too. If you’re unsure which promotion is right for you, below are the different types of bonuses for US online casinos in June 2026.

Welcome Bonuses

Welcome bonuses are by far the most popular amongst online casino platforms and players. These bonuses give you extra cash when you sign-up for the first time. 

Many of the top US online casino will offer a 100% deposit matching welcome offer, doubling the amount of money you deposit with the platform.  This is commonly known as a match bonus or a welcome offer. 

Note that no match bonus is unlimited as it typically comes with a specified cap. 

No Deposit Bonuses

Not the most popular but without a doubt the most sought after is the no deposit bonus , the reason it’s searched for its pretty self-explanatory. Who doesn’t love an offer that requires no deposit? 

This offer is typically reserved for players looking to see how different games work, along with user experience and interface operations. Activating this type of offer gives you free cash immediately upon registration.  

Recurring Bonuses and Promotions

Recurring US online casino bonuses and promotions are typically for loyal customers. Players who continue to use the same platform will see loyalty points earned with games played. Over time, operators will usually shower these loyal players with different rewards. 

Rewards can range from monthly bonus offers, timely promotions or exclusive events for big games such as the Super Bowl or March Madness.

High Roller Casino Offers

Big spenders are US online casinos best friends, and the operators will go through many hurdles to keep their ‘VIP’ customers happy. Whether you consider yourself a high roller or not will impact your promotion choice.  

These high roller casino bonuses usually see a special match offer on large deposit sums, typically at least $1K. These spenders get special treatments such as dedicated concierges and exclusive experiences. 

Free Spins

Free spins are another popular bonus promotion that US online casino players search for. This is an excellent offer to go after if you enjoy slots, which most do. 

Free spins offers don’t always require a deposit but are usually tied to a specific game. Unless an operator specifically states that you get free spins with no wagering requirements, always assume there will be wagering requirements before you’re allowed to withdraw money won in free games played.  

Mobile Casino Bonuses

There are mobile-dedicated offers that US online casinos use to push bonus offer and promotions. This is typically designed to get customers to use the mobile devices more, such as apps or HTML5 mobile-friendly websites.  

These offers are notorious for disappearing quickly, so if you see a mobile casino bonus available for a game you like then hop on it quickly. 

Sweepstakes Bonuses

If you can’t play at any real money casino because of where you live, there are always sweepstakes casinos or social casinos . These casinos let you play with gold coins or sweepstakes cash instead of real money, that you can then convert into prizes.  

Sweepstakes bonuses are some of the most popular for US online casino players outside legal jurisdiction for real money operators. Not all states have legalized social casinos though, so if you see a sweepstakes bonus you like be sure you’re in legal jurisdiction.  

How to Claim a Casino Sign Up Bonus

Claiming a casino welcome offer is quick and easy. You need to be a new customer and create a new account with the online casino. After that, the steps will differ slightly depending on the offer and the terms and conditions. Keep in mind that some casinos also require you to enter a promo code during registration - without this, you may miss out on the offer! Here’s what you can typically expect: 

1. Choose a casino sign up bonus from our list of offers. 

2. Tap the green ‘Claim’ button and head to the casino’s site. 

3. Read the offer terms and conditions carefully. 

4. Tap ‘Join Now’ and start account registration. 

5. Enter your full name, email, and personal details. 

6. Opt into the offer or enter a promo code during registration. 

7. Head to the cashier and make a first deposit, if required.  

8. Your welcome bonus will be added to your account! 

Why You Can Trust Casino Bonuses Recommended by oddschecker

There are a few reasons why online casino bonuses offered by legal and regulated gaming sites in the US can be trusted, and why they have been endorsed by oddschecker:

• Licensing and Regulation: Online casinos operating in legal US markets like Michigan, New Jersey, Pennsylvania, West Virginia, and others are licensed and regulated by state gaming commissions. These authorities set strict rules that casinos must follow regarding bonuses, wagering requirements, and marketing claims, which means they can be trusted.

• Consumer Protection Laws: Consumer protection laws in the US prohibit deceptive advertising practices. Casino bonuses must be clearly explained with fair terms and cannot mislead players.

• Audits: Regulated US online casinos undergo regular audits and testing by approved independent agencies that help verify the online casino bonuses and promotions they offer are legitimate.

• Reputation Risks: Major online casino brands authorized in the US have invested heavily to enter these regulated markets. They cannot afford any scandals around rigged or deceptive bonuses that could jeopardize their licenses and reputations. While bonus terms can still be confusing or have substantial playthrough requirements, licensed US online casinos face much stricter oversight to act transparently compared to unlicensed offshore sites

• Player Complaint Resolution If players feel any terms of an online casino bonus are unfair or deceptive, they can file complaints with regulators who can investigate and take disciplinary action.

Common Terms and Conditions

With so many online casino promos available in 2026, online casino gamblers have plenty of opportunities to win real money for free. However, we know how daunting can be to try to understand what promotions offer the best value, especially when you need to navigate through complicated terms and conditions. Luckily, we're here to help you find your way and show you how the terms and conditions impact you as a player and why some can change the value of a casino promotion in an instant.

Minimum Qualifying Deposit

You should know what is the minimum deposit amount that a gambling site attaches to a bonus before you start playing. Nearly all the offers for 'regular' new players begin at $10. Those targeting high rollers have completely different limits, often targeting deposits of $1,000 or more.

Deposit Methods

Deposit offers can be connected to specific payment methods, so it's always good to check if a casino bonus matches your preferred deposit option.

Casinos use this to push for those payment methods that make deposits and withdrawals easier and faster for players (e.g. credit cards) and exclude those with high commission fees.

Wagering Requirements / Playthrough

You will have to play the bonus amount several times before an online casino will let you withdraw your winnings.

Here the rule is: the lower the wagering requirements are, the better. Most casinos have wagering requirements that range between 25x and 40x.

A 25x wagering requirement means that you need to bet your bonus amount 25 times before you can complete your first withdrawal and cash out your winnings.

Game Contributions

Different games contribute to clearing the wagering requirements of a casino signup bonus in different ways. Most casinos apply the lowest percentile to the games with the best odds and the highest to the games with the worst ones.

That's why games like video poker and online blackjack , on average, contribute less than other ones like real money slots or scratch cards.

If you know what type of casino games you will be playing, look for a casino that applies the highest percentage to them. This way, clearing the wagering requirements will not require anything more than you playing your regular games.

Time Limit

Most online casino promotions come with a time limit that applies both to the use of the free money (or free spins) and the process of playing through to meet the wagering requirements.

Cap on Winnings

While it would be great to use casino bonuses and free spins to win an unlimited amount of money online, this is simply not possible.

Nearly all bonuses come with a cap of winning, meaning there's a limit on the money you can win with each offer.

Game Restrictions

Casino bonuses tend to be connected to specific games, especially when they come in the form of free spins or bonuses with no wagering requirements.

When this happens, you will be able to use your free spins or bonus money on specific slots and not on the entirety of the site's slot portfolio or table games.

Free signup bonus offers cannot be used to play games with progressive jackpots .

Are Online Casino Bonuses Legal in the US?

Yes, online casino bonuses are legal in the US, but it depends on where you’re located. In states with regulated online gambling, you can safely claim bonuses from licensed operators that follow strict local laws. If you’re based in New Jersey, Michigan, Pennsylvania, Connecticut, West Virginia, Rhode Island, or Delaware, you’ll have access to legal online casinos that offer a range of welcome bonuses, free spins, and ongoing promotions. In states where online casinos aren’t yet regulated, some players turn to social or sweepstakes sites.

How to Choose the Best Online Casino Bonus

Finding the right online casino bonus isn’t just about finding the biggest deposit match. The best offers combine real value, fair terms, and a realistic chance of turning bonus funds into withdrawable winnings. Here’s a few of our expert tips to look out for when comparing offers:

1. Check the Welcome Offer Value

At first glance, a large welcome bonus can seem like the obvious choice. However, its true value depends on how much you need to deposit to unlock it. The average minimum deposit is $10-$20, though you’ll sometimes be able to find no deposit welcome offers (though these are rare). A slightly smaller offer with added perks can often provide better overall value, especially if it gives you more chances to play without risking real money.

2. Read the Terms and Conditions Carefully

The fine print is where you’ll work out if an offer is really worth claiming. Look out for things like game restrictions, maximum bet limits, and any withdrawal caps tied to bonus winnings. Some bonuses may only apply to specific games, while others might limit how much you can cash out, regardless of how much you win. Taking a few minutes to read through these details can save you from frustration later down the line.

3. Review the Wagering Requirements

Wagering requirements (sometimes called playthrough requirements) are one of the most important factors in any casino bonus. They determine how many times you need to play through the bonus before you can withdraw any winnings. For example, a $100 bonus with a 10x wagering requirement means you’ll need to place $1,000 in bets before cashing out. Lower wagering requirements generally offer better value.

4. Research Potential Bonus Codes

Some of the best casino offers aren’t automatically applied, you may need a bonus code to unlock them. These codes are often featured in promotions or exclusive deals, and they can sometimes give you access to better offers than what’s advertised on the casino’s homepage. Before signing up, it’s worth doing a quick search to see if there are any valid codes available.
