Looking for ways to boost your bankroll with online casino bonus codes?
This comprehensive guide will walk you through everything you need to know about casino bonus codes – from what they are and how they work, to tips on finding the best casino promo codes available in the USA.
We’ll also highlight real examples of top promo offers from legal US online casinos like BetMGM, Caesars, FanDuel, DraftKings, and BetRivers.
Whether you’re a new player hunting for a welcome bonus or an existing player seeking free casino promo codes for existing customers, we’ve got you covered!
What Are Online Casino Promo Codes?
Online casino promo codes (also called bonus codes or coupon codes) unlock exclusive bonus offers at online casinos. Think of them as secret passwords for promotions. Casinos use these codes as a way to reward players with extra money or free spins.
Online casino promo codes are a win-win: players get real money casino bonus codes that boost their bankroll, and casinos attract new customers or encourage loyalty.
These codes don’t cost you anything – they simply unlock bonuses such as:
- No-Deposit Bonuses: Free bonus credit or spins with no deposit required (just for creating an account).
- Deposit Match Bonuses: The casino matches a percentage of your deposit in bonus funds.
- Free Spins: A bundle of free slot spins on specified games.
- Cashback/Play Insurance: Bonus credit back on losses (often for a first-day “risk-free” period).
Sometimes the casino will ask for the promo code during the account registration process, and other times you’ll enter it when making a deposit or in a promotions tab.
In many cases, especially with welcome bonuses, you only get the bonus by using the code (or special signup link).
Some casinos have started auto-applying bonuses via special links, meaning no promo code is needed, but the concept is the same. We’ll cover how to use them step by step later.
It’s worth noting that most promo codes are for new players (sign-up offers), but there are also promo codes for existing customers in certain cases.
For instance, casinos might send loyal players a code for a reload bonus or free spins as a reward or during a holiday promotion.
Overall, online casino promo codes are your ticket to extra betting money and freebies, as long as you use them correctly and follow the terms.
Note: Online casino bonuses are available in states where online casinos are legal and licensed. Always play on regulated sites and be sure you’re 21+ and physically located in a legal state to claim these real-money bonuses.

How to Use an Online Casino Promo Code
Ready to claim that bonus? Using an online casino promo code is simple if you follow these steps. Here’s a quick step-by-step guide:
Choose a Casino and Bonus Code
Pick a legal, trusted online casino in your state and the bonus you want to claim.
Copy the promo code, or if it’s a link-based offer (like some FanDuel or DraftKings promos), just click the link to activate the bonus automatically.
Sign Up and Enter the Code
Go to the casino’s website or app and register. During sign-up, look for a field like “Promo Code” or “Bonus Code.”
Paste in the code you copied, and make sure there are no typos. If the offer doesn’t require a code, the field may not appear.
Verify Your Account
Once you’ve registered, you may need to verify your email, phone number, or identity (especially if age verification fails).
Casinos won’t credit bonuses to unverified accounts, so take care of this step right away.
Enter the Code at Deposit (If Needed)
Some codes are applied at the deposit rather than the signup. When funding your account, look for a promo code field in the cashier section.
For example, if you’re using TODAYCAS2500 at Caesars, be sure to enter it when depositing. If you already entered the code at sign-up, it usually carries over – but double-check just in case.
Confirm the Bonus Is Active
After signing up or depositing, check your account to see if the bonus is credited. You should see bonus funds, free spins, or a confirmation email.
If nothing shows, don’t start playing – contact customer support first to make sure the code was applied correctly.
Use Your Bonus
Play using your bonus funds or free spins. Follow the promo rules. Some are tied to specific games, and most have wagering requirements.
For instance, CASINOTODAY at BetMGM has just a 1x requirement on the $50 no-deposit bonus. Take your time and enjoy the bonus play!
Complete Wagering & Withdraw
Once you meet any wagering requirements, your bonus funds convert to withdrawable cash. You can either cash out or keep playing.
Most casinos show your wagering progress so you’ll know exactly when you’re eligible to withdraw.
How to Find the Best Online Casino Promo Codes
Finding the best casino promo codes can feel like a treasure hunt, but we’re here to make it easy. Here are some surefire ways to track down top bonus codes for online casinos:
Casino Promotions Pages
Check the official website of the online casino under their “Promotions” or “Bonus Offers” section. Many casinos openly advertise their welcome bonus (sometimes including the promo code).
If a code is required, it will be shown in the offer details. Always make sure the offer is valid in your state before trying to use the code.
Email & SMS Offers
Once you sign up at an online casino, opt in to receive promotional emails or texts. Casinos frequently send out bonus codes for existing customers via email newsletters or text alerts.
These could be reload bonuses or time-limited offers around weekends or holidays. Keep an eye on your inbox – some of the best deals are given to loyal players.
Social Media & Forums
Some casinos announce special promo codes on their social media accounts (Twitter, Facebook) or through community forums and discussion boards. For instance, a casino might tweet a surprise code for Free Spins Friday.
Likewise, player communities (like subreddits or gambling forums) often share promo code findings.
Just be cautious: always verify that any code you find this way is from a legal US casino site. Avoid “too good to be true” codes for unlicensed offshore casinos.
Compare and Shop Around
Don’t settle on the first bonus you see. The “best” online casino promo code for you depends on your preferences. If you want the biggest bang for your buck, a large deposit match code might be best. If you prefer not to deposit initially, a no deposit bonus code is ideal.
It’s perfectly okay (even smart) to claim bonuses at multiple online casinos.
For example, you could use one code to get a bonus at Caesars and another at FanDuel – there’s no rule limiting you to one casino. Taking advantage of several welcome offers gives you more free play and helps you find which casino you enjoy most.
Things to Know About Casino Bonus Codes
Grabbing a big bonus with a promo code is exciting, but it’s important to understand the wagering requirements and terms attached to that bonus.
These terms are the “rules of the game” for your promo, and they determine how (and if) you can turn bonus funds into withdrawable cash.
Here are the most important bonus terms to watch out for:
This is how many times you need to wager the bonus (sometimes deposit + bonus) before you can cash out. It’s shown as a multiplier, like 10x or 20x.
A $100 bonus with 10x means you must bet $1,000 before withdrawing. Lower requirements are obviously better. No-deposit offers often have low playthroughs (1x–5x), while big deposit matches usually have higher ones (15x+).
Always check if the requirement is for just the bonus or deposit + bonus. For example, BetRivers had a 1x bonus-only playthrough – place a $100 bet and you’re good. Caesars had 15x, so you’d need $1,500 in bets. Huge difference.
Also, think about your budget and game style – slots eat through bets fast, but if you play slow, high-RTP games, high playthroughs can be tough. There are also no wagering casino bonuses out there, check them out.
Not all games count equally toward wagering. Slots usually count 100%, while table games like blackjack or video poker might count 10%, 20%, or even 0%. Some bonuses are slots-only or exclude live dealer games. Always check game weighting in the fine print.
A casino might say “30x slots, 60x tables”—so blackjack players have double the grind here. This is because table games have better odds for players. If you’re chasing a bonus, stick to games that count 100%.
Watch for excluded games too – some high-RTP or jackpot slots might not count or only partially count.
Bonuses have time limits. Most welcome offers expire 7 days after crediting, though some allow 14 or 30 days.
For example, BetRivers gives you 30 days. If you don’t finish wagering in time, both the bonus and winnings can be forfeited.
No deposit bonuses and free spins often expire quicker, sometimes within 24 hours. It’s best to start wagering early to avoid scrambling at the last minute.
Some bonuses, especially no-deposit ones, cap your cashout. A $20 no-deposit bonus might limit your withdrawal to $100 – even if you win $300.
Regulated US casinos usually don’t cap winnings on deposit bonuses, but free sign-up promos often do. Look for any “Maximum Withdrawal” clause. It’s rare in the legal market but still shows up in smaller offers or sweepstakes.
Always check the terms so you know the limits upfront.
Welcome bonuses are typically one per person, household, or IP address. Don’t try to game the system with multiple accounts – it’ll get you banned. If someone in your household has already claimed a code, you might not be eligible.
Most codes are for new users only, and if you’ve ever registered before – even without using a bonus – you might not qualify. Just be honest; casinos verify identities and catch out duplicates very easily.
Make sure you hit the minimum deposit for a bonus. If a promo says “100% match up to $2,500, min $20,” and you only deposit $10, you won’t get the bonus.
Same with “bet $5 get spins” or “play $1 get $100” – you usually need to deposit a certain amount first.
These small requirements trip people up a lot, so double-check the terms before depositing.
Promo codes expire or change. A code might be valid only until a certain date. If it doesn’t work, check for typos, the promo period, or updated offers.
Casinos often rotate codes for new campaigns. If in doubt, ask customer support for the current one. Don’t assume a code from a week ago is still live.
To claim a bonus or withdraw winnings, you’ll need to verify your identity and location.
Casinos may request ID or proof of address. You also need to be physically located in a legal state – geolocation will block you otherwise. Don’t try using a VPN or fake info; it’s against the rules and will void your bonus.
Stick to legal play and you’ll be fine.
Tips for Choosing the Right Promo Code
With so many bonuses out there, how do you decide which promo code is best for you?
Following these tips, you’ll be able to pick promo codes that offer practical value for you, not just flashy numbers. The “right” promo code is the one that you can use effectively and enjoyably.
Here are some practical tips to help you choose wisely and get the most value:
Match the Bonus to Your Budget
Pick a promo that fits your deposit and play style. If you’re a casual player, a huge “100% up to $2,500” isn’t necessary – you might be better off with a smaller, low-risk offer like “Bet $1, get $100.”
On the flip side, if you plan to deposit big and play often, go for the large match to get the most value. Don’t stretch your budget just to chase the biggest bonus – there are offers for every bankroll.
Consider Wagering Requirements
Always look at the rollover. A 100% match with 20× playthrough might be worse than a smaller bonus with just 1×. Lower wagering = easier profits. If you’re a low-volume player, aim for offers with minimal or no rollover.
But, if you don’t mind putting in volume, higher wagering could be worth it. Just be honest with yourself – $2,000 at 15× means $30k in bets, which isn’t realistic for everyone.
Look at Game Preferences
Choose bonuses that match how you play. Slots players are usually in the clear – most promos count slots 100%. But if you prefer blackjack or live dealer, check the fine print. Some casinos make clearing the bonus with tables tough.
Others (like FanDuel or BetRivers) are more flexible. Love slots? Free spin bonuses are a nice perk. Hate slots? Skip them. Go with the bonus that fits your actual play style.
No Deposit vs Deposit Bonuses
New to online casinos? Start with a no deposit bonus, then move on to the deposit match for more value. If you can do both, start with no deposit, then stack the deposit bonus.
No deposit bonuses give you a free taste, while deposit offers deliver bigger rewards if you’re ready to invest. Try multiple no-deposit offers to find your favorite casino, then go all in with that site’s welcome match.
Compare Total Value (Bonus + Extras)
Some codes include free spins, loyalty points, or other perks. Factor those in when comparing bonuses. Caesars gives reward points, which are great if you also bet on sports or visit their casinos.
DraftKings offers 500 free spins, giving you tons of chances to win. A slightly smaller cash bonus might be better overall if it comes with extras you actually care about. Make a quick list and choose the best full package.
Check Current Promotions for Existing Players
Already registered somewhere? See if that casino offers promos for returning users, like reloads, cashback, or weekly spins. These can offer more long-term value than a one-time welcome bonus. Some casinos reward loyalty better than others.
If one site has fewer upfront perks but hooks you up every week, it might be worth sticking around.
Read Reviews and Reputation
Promos are great – but only if the casino is legit. Stick with licensed, well-reviewed sites. Don’t fall for flashy bonuses from unknown brands without checking their licensing and reputation.
Look for recent reviews: Are payouts smooth? Is support helpful? A one-time bonus isn’t worth the headache of a shady site. Go with trusted names.
Plan Your Playtime
Only claim a bonus when you’re ready to play. If the offer expires in 7 days and you’re slammed with work, wait. Make sure you have time to enjoy it and meet the requirements.
There’s no rush – claim offers when you can use them. But, don’t let a good bonus expire!
Don’t Chase Losses for a Bonus
Once you meet the requirement, consider cashing out. Don’t keep playing just because you’re “up.” Set a goal (like double your deposit) or a loss limit. If a promo has a huge playthrough requirement that feels like a stretch, skip it; there will always be more.
Bonuses should add fun, not pressure, so never deposit more than you’re comfortable with just to “get the max.” Always stay in control.
Types of Online Casino Promo Codes Explained
Online casino bonuses come in many flavors. Let’s break down the main types of promo codes you’ll encounter, and what each one means for you:
No Deposit Bonus Codes
These are the holy grail for new players – a bonus you can claim without putting in any money of your own. No-deposit promo codes typically grant a small amount of free credit (e.g. $10–$50) or a bundle of free spins just for signing up.
Keep in mind there’s usually a catch: these bonuses often have some conditions like wagering requirements (and you may need to make at least a minimum deposit later before you can withdraw any winnings from the free bonus).
Still, they’re a fantastic way to get started without spending a dime up front.
Deposit Match Bonus Codes
Very common for welcome offers, deposit match codes reward you when you fund your account. The code will trigger the casino to “match” a percentage of your deposit with bonus money.
A typical example is a 100% deposit match up to $1,000 – meaning if you deposit $200, you get $200 in bonus; deposit $1,000 to get the full $1,000 bonus, etc. Some top casinos offer even larger matches.
Deposit match codes usually require at least a minimum deposit (often $10 or $20) and come with wagering requirements on the bonus funds.
This type of promo code is great for effectively doubling your bankroll, but be prepared to play through the bonus a certain number of times, as per the terms.
Free Spins Codes
These codes grant a number of free slot machine spins. Sometimes they’re part of a welcome bonus or given to existing players when new games launch. Free spins may come with either a fixed value per spin or be limited to specific slot titles.
For example, a casino might offer 50 free spins on a popular slot like Starburst when you use a promo code. Winnings from free spins usually convert to bonus money that then must meet wagering requirements.
If you love slots, keep an eye out for free spin promo codes, as they let you play new games without using your cash balance. (Tip: also check if the casino’s deposit match bonus includes extra free spins – many do!)
Reload Bonus Codes
These are promo codes for existing customers, used to “reload” your account with bonus funds on subsequent deposits after the welcome offer. A reload code may grant a 50% bonus on your next deposit or a fixed bonus.
Reload bonuses are usually smaller than first-deposit offers, but they’re valuable perks to keep players engaged. Casinos might offer reload codes on a weekly or monthly basis, or during special events.
For instance, around holidays, you might see reload promotions (such as a Thanksgiving bonus code emailed to players for a free $10). Free casino promo codes for existing customers can include reload bonuses, free spins, or even no-deposit credits given as a loyalty reward.
Always check the Promotions page when you’re a regular player – you might find a new code to use each week!
Cashback and “Second Chance” Codes
Some casinos offer promo code deals that ensure you play up to a certain amount. These are often advertised as cashback offers.
In practice, this means you play for a set period (usually 24 hours after your first deposit); if you lose money overall, the casino refunds those losses as bonus funds. If you win, great – you keep your winnings (but then you obviously don’t get a refund since you didn’t net lose).
Second-chance or cashback bonuses are excellent for reducing risk on your initial play. Just remember that any refunded bonus will likely have a small wagering requirement.
Not all cashback offers require a code – some are automatic – but if you see a “Second Chance” bonus advertised, be sure to enter the code if needed when you deposit.
Loyalty and VIP Promo Codes
These are less common as codes (since VIP perks are often automatic), but occasionally, casinos will give out special codes to their VIP members for extra bonuses. Also, some loyalty programs let you redeem points for bonus codes or free play.
While you won’t usually find these codes publicly listed (they’re targeted to specific players), it’s good to be aware that as you stick with a casino, you may earn exclusive promo codes as part of loyalty rewards.
Refer-a-Friend Codes
Traditional refer-a-friend bonuses usually use referral links rather than promo codes, but we’ll mention it here. If a casino does have a refer-a-friend promo code, it might be a code your friend enters (like your username or a refer code) to give both of you a bonus.
For example, if your friend uses your referral code, you might get a $50 bonus, and your friend gets $50 as well. Most US online casinos handle this with links/invites, but the result is similar to a promo code bonus.
Check the casino’s referral program details – it’s a nice way to get extra bonus money on top of other offers.
Online Casino Promo Codes FAQs
Let’s go over the most frequently asked questions our readers have about online casino bonus codes and their usage.
Yes. As long as you’re using them at a licensed online casino in a legal state like New Jersey, Pennsylvania, Michigan, etc. You must be 21+ and physically located in the state. Promo codes are totally legal and just part of the casino’s marketing.
Not always. Some codes unlock no deposit bonuses – you get a reward just for signing up. Others, like deposit match offers, require you to deposit before the bonus kicks in. There are also hybrid codes that give a little for free and then more when you deposit.
Yes! Once you’ve used a welcome code, you won’t get another one at that casino, but you’re not out of luck. Most sites offer reload bonuses, cashback, free spins, and other promos for returning players. Some require codes, some don’t.
Check the site’s promotions tab and keep email/text alerts on to catch the best offers. Loyal players often get regular treats, especially around holidays or special events.
The “catch” is usually the wagering requirement. You have to bet the bonus money a certain number of times before you can withdraw it. But yes, you can win real money – people do all the time.
Just know the bonus isn’t instant cash; you have to play through it first. Time limits and game restrictions can also apply, so read the fine print. Treat it like a fun boost, and if you win? Even better.
Usually not. Casinos only allow one active bonus at a time, especially with welcome offers. You can’t combine two codes on the same deposit unless the terms say otherwise.
That said, many sites let you use a no-deposit bonus first, then a deposit bonus after. If you want multiple offers at once, just sign up at a few different casinos. One site = one bonus at a time.
First, double-check the code and make sure that the spelling is correct and that there are no extra spaces. Then, confirm you met all the requirements, like a minimum deposit or being a new user.
Still not working? Reach out to customer support with the code and promo name. Most casinos can credit the bonus manually if there’s an issue. It helps to keep a screenshot of the promo, too, just in case.
Promo codes change regularly. To stay up to date, come back to this page often, check casino promo pages, sign up for emails from the casinos you like, and follow them on social media.
Keep an eye out around holidays or big events – casinos often roll out limited-time offers. It pays to stay in the loop!
Final Words on Promo Codes
By now, you should feel confident about finding and using online casino promo codes. These bonuses are a fantastic way to enhance your online gambling experience, giving you extra chances to win and longer playtime without additional cost.
Just remember to gamble responsibly: use these promo funds for entertainment and potential profit, but never chase losses or view bonuses as a guaranteed income. The house still has an edge, but promo codes tilt the odds slightly more in your favor by reducing your risk and increasing your reward.
With the info shared above, you’re equipped to make the most of the offers out there. So go ahead and explore the legal online casinos available to you, claim those bonuses, and most importantly, have fun!
