BonusFinder Tip

Big doesn't always mean best. Smaller offers often come with easier wagering and faster payouts.

Types of Casino Welcome Bonuses

There are several types of casino welcome bonuses you can choose from. The best online casino bonus codes range between $40 to $2,500, and you can claim all offers in your state if you want to. Here are the types of bonuses you're going to see:

• Deposit Match Bonuses: The classic — casinos match your deposit up to a set amount.
• No Deposit Bonuses: Free funds on signup, no deposit required. Usually $10–$50.
• Free Spins: Great for slot fans.
• Cashback/Lossback: Play games with a safety net.
• Social Casino Bonuses: Free coins and sweepstakes prizes where real-money casinos aren't legal.

1. Deposit Match Bonuses

Deposit matches are the most common online casino offers in the US. You can get big or small bonus offers, depending on your style of playing and how much of your own money you're ready to deposit. Some of the best online casino bonuses are available only in certain states: make sure to check yours from the top of this page.

The benefit of these bonuses is that you can play nearly any game with them (but do check the T&Cs before claiming each bonus). In addition, you can choose the amount of the bonus you want, up to the cap.

The Best Deposit Offer for New Users

The award for the best deposit bonus casinos in the USA goes to two different US online casinos; Caesars and FanDuel.

If you are looking for a big welcome bonus to spend on the slots, take a look at Caesars and grab $1,000 in casino credits with a 15x playthrough requirement. You also get a sweet $10 no deposit bonus upon registration!

If you want to get the most out of your money, take FanDuel's offer. You only need to deposit $10 to get 500 spins and $40 on the house! You need to play your spins just once before you can cash out your winnings.

2. No Deposit Bonuses

No deposit bonuses are exactly what they sound like: welcome bonus cash, no deposit required.

Regulated casinos in the US give out between $10 and $50 in bonus funds. You can find up to $200 no deposit bonus casino offers by combining offers from multiple casinos.

You can find the most bonuses in NJ, but all legal online casino states offer some form of no-deposit online casino bonus. A couple of social sites also offer a Bitcoin casino no deposit bonus.

The Best No Deposit Casino

BetMGM is the best real money online casino for no deposit offers in the US for several reasons. First, they have a $25 no deposit sign up bonus. They also have an impressive deposit match (up to $1,000 in casino credits) if you want to fund your account further.

Secondly, they are available in all the legal gambling states. Thirdly, their selection of the best online slots, tables, and free scratch off games is excellent.

Note that the no deposit bonus is a secondary offer, as the current primary offer is a big $2,500 deposit match and 100 spins.

3. Free Spins

Free spins no deposit win real money bonuses are still quite rare in the US compared to free and first deposit online casino bonuses. However, this welcome bonus is still available either as no deposit spins or bonus spins with a small deposit.

This is often game-specific and rarely applies to new games, but there are plenty of options to play with most free spins offers.

Top Free Spins Bonus

The best spins casino site isn't that hard to find. FanDuel gives you 500 spins for Huff N'More Puff with only a $10 deposit. Smaller free spin amounts are available without a deposit, like on Harrah's online casino.

4. Other Types of Bonuses

In addition to the main types listed above, some real money casinos in the gaming industry offer losses back/cashback bonuses. These offers are great since you make a deposit, play online casino games, and get compensated in site credit for your losses.

A bonus type that's growing in popularity is 'Do X, Get Y' offers. These are also great, since you often have to place just a small initial deposit to get the bigger offer. The site credit often has just 1x wagering, which is great, especially for new players.

Free chip bonuses have gained significant popularity recently. You have the option to convert your no deposit bonuses into no deposit free chips and enjoy playing the available games. You can get a $75 free chip no deposit combined bonus from various sites.

The Best Alternative Casino Offer

Honestly, any of these types of bonuses is a great option, but if you want to get the most out of it, FanDuel has the best online casino bonus. On the other hand, Bally Casino site offers cashback, which means there is no wagering requirement!

5. Social Casino Bonuses

If you don't live in states where real money online casinos are legal, you can still claim welcome bonuses from social casinos. These sites offer free coin bonuses which let you play for free; you can also purchase better casino bonuses! You can find a list of social casinos USA on BonusFinder US. Most of them accept players from nearly all states so there are plenty of options.

The Top Social Casino Bonus

The best social casino bonuses are offered by Wow Vegas, High 5 Casino, and Chanced.com. If you've already claimed those, we have several different options to pick from. You can always play entirely for free as sweepstakes casinos offer daily bonuses as well. What's even better, you could even win real money prizes with these bonuses!

Casino Bonus Codes

Basically, every online casino in the US offers casino bonuses. These offers sometimes require you to insert a bonus code. For instance, you need the BetMGM bonus code FINDER2500 or FINDERMI2500 to get the welcome offer when creating your account. Make sure that you deposit at least the minimum amount as well.

Using Casino Promo Codes

To claim online casino bonuses, you need to use the promo code in the required field. Usually, the online casino will give you the chance to enter the code in a designated field when you register a new online casino account. This method will help you claim various promotions from our 100 Dollar Free No Deposit Casino list.

How to Choose the Best Sign-Up Bonus for You

We've chosen BetMGM as the best casino bonus, but you might have another top pick. Here are the steps to choosing the perfect site for you:

No Wagering Casinos

No wagering casinos in the U.S. are rare. That said, low-wagering options like DraftKings Casino exist. These casinos offer quick and easy cashouts for excellent value! You can also refer to our review of free spins no wagering casinos in the United States.

How to Calculate Casino Bonuses

Calculating how much bonus money you will get for each offer is extremely simple and probably quite self-explanatory. Here are tips that you can apply for most casino welcome bonuses:

1. No Deposit: As implied by the name, you get these types of bonuses for free. This means no calculation necessary! You just complete the required steps and the bonus is placed on your account.
2. Deposit: To claim a deposit offer, you need to make a deposit. This deposit is then matched up to a certain percentage. For example, If you get a 100% up to $500 bonus by depositing $200, the calculation is: $200 + (1x$200) = $400. If you claim a 125% up to $500 bonus with the same deposit, you would get $200 + (1.25 x $200) = $450 to play with.
3. Cashback/Losses Back: Finally, this one can be a bit complicated at first. If you deposit $500, play games with that amount, and end up with $300, you will get $500 - $300 = $200 back as bonus money or cash at cashback casinos. If you end up $550, you don't get any money since you didn't accumulate any losses!

Casino Bonuses' Terms & Conditions Explained

Casino promotions come with attached T&Cs, and online casinos require that you follow them. These requirements might be a bit confusing to new and experienced players alike.

Therefore, we explain the most common T&Cs that new players need to know when creating an account or making their first deposit. Always read the small print on the casino operators' pages as well!

Wagering Requirements

Casino sites don't just hand out free bonuses or deposit matches to players as cashable funds. In order to cash out your casino promotion, you need to fulfill wagering requirements. You have to wager a set amount by playing video slots or card games.

Usually, the best bonuses are from low wagering online casinos. In the US, these playthrough requirements are quite lenient, usually at around 15x for online slots. The difference to Europe or the United Kingdom is huge, where it's common to get 35-70x wagering requirements.

Practical Example

Let's say you receive a 100% up to $1,000 match from Borgata. It has a 15x wagering requirement, meaning you'll have to wager $15,000 to cash out. While this sounds like a lot, it's actually one of the most lenient wagering requirements in the industry!

Game Contribution

Not all games contribute equally when it comes to wagering requirements. Online slot games, including fish table games, usually contribute 100%. Games with high RTP, such as progressive jackpots or video poker, might only contribute 20% towards wagering.

So, instead of looking for Roulette bonuses, claim the welcome bonus and play other games to complete the wagering. Once you've completed the wagering, you can play all kinds of games and get to cash out winnings immediately. Check the table below for common game contribution rates:

Game Restrictions

Most real money gambling sites exclude certain games and online slots from bonuses because of their high RTP. Progressive jackpot slots, online lottery games for real money, real money online keno, and live games are usually excluded.

Therefore, always check the fine print for the restricted slots and which games count as eligible games. Our recommended online casinos let new players use their bonuses on a wide selection of games.

Minimum Deposit Amount

Minimum deposit is the amount that you need to deposit to qualify for the bonus. There are some $5 deposit casinos, but the qualifying deposit could be as high as $30. The minimum deposit requirement should always be listed clearly.

Max Bonus

Maximum bonus describes the maximum amount of extra funds available with a single deposit. For example, the primary bonus on BetMGM gives new players a 100% up to $2,500 bonus. This means that if you deposit $2,500, you'll receive $2,500 extra.

However, if you deposit $1,250, you'll still only receive $1,000, as that's the max bonus. The bonus percentage tells you how much to deposit to get the offer.

Wagering Time Limits

Most casinos usually attach a time limit or an expiration date to their online casino bonus. This means that you have only a certain amount of time to wager through the money. A typical requirement ranges from 7 to 30 days.

This might sound like a short time, but you go through it quite quickly. Just imagine how quickly the reels spin on a Las Vegas casino slot machine: it's the same thing online.

Max Bets

Deposit casino bonus terms also often indicate a max bet. Although the original game provider might have a $100 max bet for the game, a casino might restrict the maximum bet to $10 to prevent huge losses.

Rewards Programs & Other Casino Promotions

If you want to keep playing games, consider joining loyalty programs or VIP programs to get loyalty bonuses. You can receive news, exclusive offers like a monthly bonus, and many other types of benefits when you regularly visit a casino online.

Almost every top casino provider has a rewards program in the US; the most popular ones are Caesars Rewards program and MGM Rewards program. Other great rewards programs are Dynasty Rewards and Wynn Rewards.

Casino operators also reward existing players with reward credits and site credits. For example, if you play Blood Suckers with $25, you get 25 spins to play a new game on the platform. Unlike sign-up bonuses, you can opt in as many times as you like to get these casino cash prizes.

There are many different forms of daily and monthly bonuses, so head over to the Promotions page on a regular basis to claim a bonus and other rewards.
