Caesars Palace Online Casino – Best for welcome bonuses
Caesars Casino has become a top option among leading brands in the US gaming industry. The site’s welcome bonus fuses three distinct promotions into one. First, Caesars online casino is a free bonus no deposit casino: you get a $10 sign-up bonus. Second, you get a 100% deposit match of up to $1,000. On top of that, wagering at least $25 earns you 2,500 credits in the Caesars Rewards program, considered the best in the industry. The casino sign up bonus code for this offer is FREELAUNCH.
Caesars sets fair terms for its online casino bonuses. For example, you only need to wager the $10 sign-up bonus 1x on slots, or 2x on video poker, or 5x on other casino games to claim your winnings.
In addition to the welcome bonus, Caesar has other benefits as well. For one, there is an extensive library of games. There are hundreds of slots, traditional table games, and even poker. Popular software providers like IGT, NetEnt, Playtech, and Big Time Gaming supply all the games. The casino’s website works well with both desktop and mobile devices. So, whether you prefer to play on the go or in the comfort of your home, you can fill in your online bonus code easily. The website is also smooth, and navigation is easy. Finally, once you join this online casino, you will enjoy steady and rewarding experiences that deliver real value.
Quick Facts:

BetMGM – Best no deposit bonus code
One of BetMGM’s standout features is a strong game selection, the largest in the industry, featuring tables, slots, and live dealer options.
However, the platform’s promotional offers are also generous, with the welcome bonus particularly appealing. As a new player, if you use the online casino bonus code PLAYUSA100, you will receive a $50 casino no deposit bonus once your verification is complete, which is the highest USA no deposit bonus code. Additionally, you are also eligible for a 100% deposit match promotion worth up to $2,500, another solid total. The minimum deposit for claiming this part of the bonus is $10. And in WV, you also get 50 bonus spins.
BetMGM is recognized for fair terms, applying just a 1x wagering requirement to its $50 casino offer. The 100% deposit match promotion has a 15x playthrough. BetMGM applies similar conditions across many of its bonus offers. As a result, this online casino is known as one of the more player-friendly choices when selecting platforms with reasonable terms and conditions. BetMGM is also known for its sportsbook, reliable payment options, and active customer support.

BetRivers does not complicate the welcome packages like some of its competitors do. To welcome you to its platform, BetRivers provides a total bonus of $500, with only a 1x playthrough. The BetRivers casino sign up bonus code for the welcome offer is RIVUSA.
The game library is modest but delivers quality experiences through its slots, table games, and live dealer options. It might not have the most extensive library compared to giants like BetMGM. However, it compensates for this by offering quality games sourced from top developers in the iGaming industry. The iRush Rewards loyalty program is another standout feature you will enjoy. This loyalty program offers various perks, including bonus store points and rewards.
On the downside, BetRivers could offer more variety in its promotions. However, it remains a strong option for players seeking a fair and straightforward experience. The website has a clean interface and a dedicated mobile app. Customer support is also reliable, and you won’t need to wait too long to get the help you need.

Horseshoe – Best for mobile gaming
Despite being relatively new, Horseshoe has earned a fine reputation within a short time. A big part of the reason is the impressive welcome offer you get with casino bonus code FREEWW. To begin, you get a 100% deposit match bonus worth up to $500. Next, you will receive 20 bonus spins for the Double Top Dollar slot. You are also eligible for second 100% deposit match bonus up to $500 for your second deposit.

Apart from this welcome offer, Horseshoe also provides a good mix of slots and live dealer games. The live casino is outstanding, with over 35 options to pick from. Although smaller in comparison to other betting platforms on this list, the live dealer options still stands due to the quality experiences it provides.
Horseshoe’s integration with Caesars Rewards is another crucial feature that makes the site a top option.

Types of casino bonus codes explained
Each casino bonus code is distinct and created for a specific promotion. Its important you understand how they function in order to select the most suitable offer for you. Here we list out the types of bonus codes based on the promotion they are created for.
Welcome bonuses
The most common online casino bonus codes by far are those for welcome bonuses, the first rewards you get for signing up as a new player. Bonus codes tied to welcome offers basically give you some pretty impressive incentives for giving the site a try. Here are some of the common types of offers you will find:
- No deposit bonus codes: Real money online casino no deposit bonus codes are the most popular bonus codes for online casino players. You simply enter a code, and you get instant cash or spins without needing to deposit. You can’t cash them out right away, but you get a chance to try the games, and if you win with those credits, you can then cash them out. Free casino bonus no deposit codes are excellent if you are looking to try new games without risking your funds.
- Bet and get codes: For these offers, you place a small bet with the casino and receive a bigger reward. For example, bet $10 and win $50 in bonus credits.
- Deposit match bonus codes: Here, the casino will instantly match your deposit. Usually, the match will be 100%, but sometimes it’s only 50% and sometimes it’s 200% or more. Simply enter the promo code, make your deposit, and multiply your bankroll instantly.
- Free spins codes: These online casino promo codes will provide several free spins for slot games (or in some case, bonus spins more accurately because you have to make a deposit). In most cases, the casino will indicate the slot titles to which the free spins apply.
- Cashback bonus codes: With cashback codes you get a percentage of your losses (usually 100%) back as a bonus. Note that the credits you get back will be for your net losses over the specified period of time (usually one day or one week), not covering any individual.
- Bonus codes for extra Rewards Program Points: These are codes that award loyalty or VIP points. With these points you get to enjoy perks like faster withdrawals, exclusive games, or luxury prizes.
Bonus codes for existing players
Bonuses go way beyond just your first deposit at the best online casinos. Casinos also use them to reward their loyal and returning customers. These casino bonus codes often come in the following forms:
- Reload bonuses: These are minor versions of welcome bonuses. You must type in a code on subsequent deposits to receive additional cash or free spins.
- Free spins on regular play: Most casinos send codes via email or app alerts to their existing users, offering free spins. You simply need to copy the codes and apply them.
- Seasonal/event codes: You may occasionally see special online casino promo codes with added perks during holidays or special events.
- Cashback offers: Some sites require a code to activate weekly casino cashback promotions. Applying the code correctly helps you get back a portion of your losses from the previous week.
The majority of casinos will either email you these codes or send them as a push notification from top online casino apps. Some of them also appear in the promotions tab within the platform. Ensure you monitor these channels of communication to avoid missing out on worthwhile offers.
State-specific online casino bonus codes
As you might expect, not all casinos offer the same casino bonus codes everywhere. In the US, each state has its own individual gambling and betting laws. As a result, operators sometimes vary their welcome offers based on where you play. For example, BetMGM offers bonus spins for West Virginia players that is not available in other states. And for BetRivers, the bonus comes in the form of a deposit match in PA but a cashback bonus in other states.
Another factor to consider is that not all casinos are available in every state. Some online casinos may be available in New Jersey, for example, a state that offers more licenses, and unavailable in other states. In Delaware, the BetRivers bonus code is the only one you can claim.
The bottom line is that you must always make sure that the bonus code you select matches the state you are playing in. You can click on any of the links below to learn more about the bonus codes available in specific states.
How to use online casino bonus codes
You can claim and use a casino bonus code within a minute or two while signing up for an online casino. Follow the steps below to do so:
1. Pick a licensed casino site: As your first step, ensure your selected casino is duly regulated. Also, check the site’s promotions page and check the terms of the bonus first.
2. Create your account: When signing up, use your actual information, including your real name. Doing this is essential to avoid complications when withdrawing. Verify your age and location. Also, look for spaces to enter a bonus code, if it’s not already pre-filled for you. Caesars Palace online casino is a great example of how this works. If you click using a link on this page, the code will be automatically applied, as it is in the screenshot below.
Or, if you just went to the site on your own, you can click the text that says “Have a different promo code?” and enter the casino bonus code there to get the best deal.
3. Opt in (if required): Certain casinos require you to manually opt in for bonus offers. If your selected casino has this requirement, make sure you click the buttons that indicate your desire to receive bonuses.
4. Navigate to the cashier tab, if a deposit is required: Of course, at some sites, you get a free casino bonus no deposit code. However, at most sites, you need to make a deposit to activate the bonus code or to withdraw your winnings. If so, find the cashier section. Usually, right in the main lobby, you will find a button to get there. If not, you go to your account profile and it should be right there. Almost always, you will find it in the right-hand corner on both desktop and mobile. A perfect example is FanDuel Casino, where you can click the green plus to add funds directly or click on the little person icon to go to your account and enter the cashier that way.
5. Make an eligible bet or deposit: Choose your payment method and satisfy the online casino minimum deposit requirement by funding your account with the appropriate amount. Usually, the minimum deposit for the site as a whole is a the minimum deposit needed to qualify for the bonus code offer. (So, a $5 deposit casino will require $5 for the bonus.) But sometimes, you need to deposit more than the minimum to claim a bonus code. For example, PlayStar Casino is technically an online casino with a $10 minimum. But we put it on our $20 deposit casino list because that’s how much you have to deposit to unlock the welcome offer.
Also, be sure to identify which methods are eligible for promotional offers. Deposits using prepaid cards and certain ewallets are sometimes not eligible for bonus offers. Also, at some sites (like BetRivers), you also need to put a bonus code here to get the offer. And with certain bonus code offers, you don’t activate the promo until you have played some games.
6. Check the bonus confirmation: Look for the bonus message after meeting the requirements. Always keep in mind the time limit attached to the promotional offer.
7. Track your progress: Use the bonus tracker to monitor your activities. Always play eligible games and do not try to withdraw unless you complete the wagering requirement.
8. Complete KYC: You need to upload some documents to complete your verification process. Doing this promptly helps you avoid delays when you want to withdraw your winnings.
9. Withdraw your winnings: Once verification is complete and you meet all playthrough requirements, cash out your winnings.
Troubleshooting tips
Here are some quick tips to avoid errors or difficulties with bonus codes:
- Codes are case-sensitive, so copy and paste each code.
- Expired codes won’t apply, so ensure to check the dates before reapplying.
- First-time user rules matter, since you can’t claim the same code twice.
- When a code is not working, pause and reach out to support before you begin to play.

Casino bonus codes provide you with a chance to start your player journey on the right foot. But they aren’t free money. They come with terms and conditions attached to them before you can use them and before you can withdraw anything. Here is a quick explainer of some of the main terms you need to analyze:

Some casinos do not require a bonus code. Instead, you get the bonus automatically as you sign up or make a deposit. Other casinos will prompt you to enter a code when creating an account. Always check the details of any promotion to get a better understanding before claiming.
A no-deposit bonus will provide you with free cash to play for simply signing up to join a casino. On the other hand, with online casino free spins you get a certain number of bonus spins for slot games. Both of these bonus offer offer chances to experiment with a casino without spending your own money yet.
Most online casinos only have one running bonus at a time. As a result, you can only use another bonus code if your current one has expired or you cancel it.
That said, you can absolutely sign up for as many online casinos as you would like and claim the promo code offer for all of them.
Real-money casino bonus codes only work in states where online casinos are legal. Currently, these include New Jersey, Pennsylvania, Michigan, Connecticut, Delaware, Rhode Island, and West Virginia. However, there is an expectation that more US states are likely to legalize online casino gambling soon.

Yes. But with the condition that you have complied with the rules. You will always have to use the credits on a game at least once before withdrawing. You may have to use the bonus to play only specific games. Also, the majority of no-deposit codes limit how much you can earn with the bonus funds.
Yes. Bonus codes are official offers from casinos. They are made to appeal to new players and also reward loyal and returning players. All you need to do is ensure that the casino site is legal in your state or jurisdiction. If so, the site is regulated and trustworthy. If not, you have no legal recourse if the casino pulls any shady tricks.
