States with online casinos and bonuses
Considering how deeply we need to dive into bonus specifics, it’s crucial to point out that online casino gaming is legalized on a basis that varies by state. Available games, bonuses, age requirements, and more can differ by location. Sadly, you can indulge in online gambling only in certain states that have specifically legalized this form of play. Surprisingly, right now you can participate in lawful online casino games and claim enticing bonuses in the following states:
If you’re not physically located in one of the previously mentioned states, you won’t have the opportunity to play a real money casino game online or obtain a casino bonus. Numerous casinos provide free-to-play trial versions of their games, usable outside approved areas, but real money play is restricted. Remember, all users must download a plugin or activate geolocation services on their devices to confirm their location before participation. Stay alert to these requirements.
The promising news is that more states adopt this regulation with each passing year. Although New Jersey was on an isolated iCasino path for years, others are now treading in the Garden State’s direction. Pennsylvania started operations in 2019, West Virginia launched in 2020, and Connecticut with Michigan joined in 2025. Surely, more will follow this trend, so stay informed!
Online casino promo codes explained
How do you claim an online casino bonus? Many online casino bonuses will ask the user to enter a special promo code or bonus code during sign up or when depositing. The promo code lets the casino know that we sent you, and in turn, they’ll hook you up with our Casino Sites Pro offer. Using the wrong promo code, or going without entirely (gasp) will cost you free money. Online casino games are fun, and they’re the most fun when you’re playing with house money. Before you sign up for a new online casino be sure to check with us first to make sure you’ve got the right code and can claim the best offer.
Keep in mind that some online casinos will label these codes as ‘Promo Codes’, others will use ‘Bonus Codes’, and it’s possible you’ll see some other variants, too. For all intents and purposes, they mean the same thing. If there’s a blank field during sign up or when depositing with the cashier that mentions a code, slap ours in the box in you are good to go.
casino-sites casino promo codes will get you better offers
Now that you know why you need a casino promo code, you may be asking, why use a promo code? To put it simply: we’ve got connections. With years of in-industry experience under our belt, we’ve built positive working relationships with the countries top online casinos. In turn, they’ve hooked us up with the best available offers. Using an exclusive promo code will add more value to your online casino play than others. The offers available to the general public don’t stack up with the deals.
Identifying a good casino bonus
Online casino bonuses come in all shapes and sizes. There are free money offers, free spins, deposit match bonuses, bonus plays, and much more with figures ranging from $10 up to thousands being tossed around. So the big question is, how do you know a good bonus from a bad bonus? It’s really all about the details… and by details we mean wagering requirements.
Always read the terms & conditions
Before tackling a casino bonus make sure you read the terms and conditions. It may seem tedious but it’s an incredibly valuable part of the process. Generally speaking the T&C will tell you if the offer is worth your time. Some bonuses may seem like an incredible opportunity on the outside, but when you dig in, the value just isn’t there. If you’ve got questions about a specific offer, refer to our Casino Sites Pro online casino reviews. We do the math for you, and break down all the t&c’s in terms anyone can easily understand.
Wagering requirements: Bigger bonuses aren’t necessarily better
All online casino bonuses have some sort of wagering requirement attached to their offers. Without them you could claim the bonus and then bounce immediately with the free money. Casinos make money, but they can’t give away the store – so to speak. Before you can cash out your iCasino bonus you will need to play some games. That’s where the wagering requirements come in.
Let’s say you’re about to sign up on a new online casino and have narrowed it down to two options:
- Casino 1: Offering new players a 100% up to $1,000 deposit match bonus
- Casino 2: Offering new players a 100% up to $250 deposit match bonus
Which offer are you picking? It seems like a no brainer… $1,000 is bigger and better than $250, right? Not so fast, my friend. You have to check the terms and conditions and scope out the wagering requirements first. Keep an eye out for the playthrough rate, which should be listed clearly. The playthrough rate signifies how much you’ll need to wager before you can withdraw the bonus. If the playthrough rate is 10x, you will need to wager every dollar you took in bonuses 10 times before that money is yours to keep. Rates across the industry generally range from just 1x (a great offer!) up to 40x+ (not so great).
Therefore, in the above example, if the $250 match bonus has just a 1x playthrough, that promotion would be far more appealing than a $1,000 bonus with a 10x+ requirement. The smaller offer would be significantly easier to clear and take to the bank, while the larger would require you to wager tens of thousands to unlock. The devil is in the details, it is vital you make sure you check the wagering requirements!
That being said, just because an offer has higher requirements, does not make it a bad value. Generally, online casino games have a much higher return rate than their retail counterparts. Where the average in-person slot game will only average around 88% return, most online slot games offer a 95% return on your money. It is fully up to you where you want to start. A $250 1x is quick and easy, where a $1000 10x will take more time, but may be worth more in the long run.
Look for qualified games restrictions
Once you’ve nailed down the wagering requirements and playthrough rate, look for qualified games. Some casinos restrict the games that you can play to clear a bonus. For example, a bonus might have a 1x playthrough but it has to be cleared by playing slots. If you enjoy slots, that’s not a problem… but if you only really enjoy playing blackjack, baccarat, or other table games, that offer won’t be worth as much to you.
Sometimes casinos will even restrict you to certain slot titles. They may provide a list of slots, typically, if restricted, it will be the high ‘return to player’ machines that don’t qualify. Other times the casino may list various contribution percentages. In these sorts of scenarios it might have slots with a 100% contribution percentage, meaning $1 wagered at slots will count as $1 towards the clearance of the bonus. However, a game like blackjack might be at 20%… meaning for every $1 wagered at a blackjack table you will only clear $.20 of the bonus.
While the wagering requirements tell you how much you need to play to clear the bonus, the qualified games tell you what you need to play.
Check the expiration date
Online casino bonuses don’t last forever and knowing the expiration date will greatly inform your strategy. Generally speaking, users are given a specific window of time to clear a bonus offer. Once it expires, any uncleared bonus is lost. Expiration dates typically range from as little as three days to as much as 90 days. The longer you have to clear the offer, the better.
With that being said, don’t let a shorter expiration date turn you away. These offers are still worthwhile… but just make sure you have enough time to play to finish the requirements in time. In other words, if you don’t use it, you lose it.
Types of U.S. casino bonuses
Legal U.S. online casinos generally rely on a few different types of welcome offers. While at times you will see others, the following promotions are the most common. Keep in mind it may be possible to claim more than one at a time, too. Some casinos may offer a welcome package combo that includes both a free money component, and a deposit bonus. The best of both worlds.
Online casino free money, no deposit bonuses
We’ll start off with the best of the best. You simply can’t top a free money bonus offer. No deposit bonuses are promotions that you can take full advantage of without making a deposit. Yes, you read that correctly. Since no deposit is required there’s no financial risk to the user. No deposit bonuses are typically pretty small, since the casino is literally passing out free money, but what have you got to lose? Free money offers can typically net you between $10 and $30 which you can use to splash around and try out a few games. It will be a challenge to build a bankroll from, but it’s certainly worth the effort to try.
Like all legal online casino bonuses, free money offers come with T&C so be sure to read them. This is a marketing tactic to get you to try their product, so the casino isn’t just going to toss you $30 bucks and let you withdraw it right away. You will need to fulfill the wagering requirements before the bonus (and any winnings from using it) are withdraw-able… but again, it’s all free anyway.
Casino deposit match offers
Deposit match bonuses are as advertised: you deposit some cash, the casino matches it with a bonus. Match offers are described with a percentage, and a maximum cap on the bonus. For example, a 100% up to $500 deposit match bonus means the casino will match all of your deposit (100%) up to a total of $500 and you will start out with a $1000 bankroll. While you could still deposit more than $500, the bonus you receive would be capped at that amount.
An example of a casino deposit match offer would be WynnBet Casino promo code offering $1K Deposit Match, or Hollywood Casino promo code granting $502 Deposit Match.
Making a deposit will allow you to earn far more in bonuses than solely relying on free money offers. Deposit match offers regularly balloon to over a thousand dollars, but as we’ve discussed, you’ll need to hit the tables before you can pull the bonus money off the site. If you’re ready to grind, a deposit match bonus is right up your alley. Read the terms and conditions before depositing to make sure you’re not caught of guard by the bonus requirements.
Cashback bonuses – claim a refund
Cashback casino bonuses are essentially a refund. After you sign up and make a deposit the casino will comp you a period of time where you can more or less gamble bonus. If you have lost money at the end of the time period they’ll credit you with a bonus equal to the amount lost. Obviously, there is a limit to the potential refund, usually $100 – $500, but they’re still very valuable. Cashback offers aren’t found as regularly as the other promotions, but they’re definitely worthwhile.
Now, if you don’t start off hot and you do need the refund to bring you back to even – keep in mind that you will still need to satisfy the wagering requirement. Any bonus bucks the casino credits you will need to be wagered through, but usually are only 1x. So once again… familiarize yourself with the terms and conditions.
Free slot spins
Free spins are rarely a focal point of an online casinos offer, but more of an added cherry on top. To incentivize slots action online casinos will regularly toss in some free spins on one of their preferred machines. It’s hard to assess the overall value from free spins as your takeaway can vary greatly… but either way they’re a good time and should provide some enjoyment. That’s what it’s all about, right?
Mobile casino bonuses
Mobile casino bonuses are actually the same as a standard online casino bonus. The majority of legal U.S. online casinos offer games through a web-browser based casino for use on a computer, plus a savvy mobile casino app on both iOS and Android. Once you claim a casino welcome bonus you can clear it while playing on any device, it all counts as the same offer. You can register via mobile and play on your computer, or vise versa. Play on the platform you prefer.
Clearing your bonus: Make a plan
Online casino bonuses can be hard to clear, but they’re not impossible. Finishing an offer can be extremely lucrative so it actually pays to approach it the right way. Here’s our advice on how to attack an online casino offer:
- First up, read the terms and conditions! We may seem like a broken record here, but the importance of knowing every detail about the offer can’t be understated. Keep an eye out for the key points we discussed above: wagering requirements, restricted games, expiration dates, etc.
- Next, carefully consider your game selection. All online casino titles will have a specific Return to Player rate (RTP). The RTP determines how much cash you can expect to win back for each dollar you spend. For example, a high return slot may award 97%+. At 97%, if you wagered $100, on average, you can expect to win back $97 of it. Needless to say, the higher the RTP the better.
- Finally, develop a plan. Once you know all of the bonus terms, the games you want to play, and the size of the bonus you’re going to be clearing, you can lay out a strategy. If you’re going to clear the bonus playing blackjack, you can estimate out how many hands you’ll need to play and at what stakes to complete it within the given time frame. If you are playing slots, pick the machine(s) that you’re going to focus on and how many spins it might take. Nailing down these sorts of details beforehand will greatly increase your chance of maximizing the offer.
- Last but not least, have fun with it. Online casino games are a form of entertainment, enjoy them!
Online casino VIP rewards
Completely separate from the welcome bonus, many online casinos have developed a sophisticated online casino loyalty rewards program. Some online casino VIP programs are tied to their brick-and-mortar set ups like BetMGM and its MGM Rewards, while others are online-only. Either way, we highly recommend familiarizing yourself with any and all available benefits. Generally speaking, the more you play, the more you stand to get back in value. Rewards programs often pay out in the form of room comps, show tickets, and other in-person benefits… but sometimes you can actually unlock valuable online casino bonuses. For example, you may be able to cash in rewards points in exchange for a special bonus. VIP bonuses will still need to be cleared, like all offers, but they will still contribute to your bottom line.
Online sportsbook bonuses
Many online casinos also offer sports betting services, opening the door for sportsbook bonuses. Some sites that offer both may allow you to claim a sports bonus and a casino bonus, some you may have to pick one or the other, and other sites may offer one comprehensive bonus that you can clear by playing multiple products. Regardless of how the offer is structured, if you’re interested in sports betting there are bonuses available. Check them out.
