Best Online Casino Bonuses and Welcome Offers for US Players 2024

Online casino bonuses and welcome offers help players increase their bankrolls and try out casino games.

The most common types of casino welcome bonuses include no-deposit bonuses, deposit-match bonuses, risk-free bets, and free spins.

Use your bonus to play slots, table games, live dealer games, game shows, arcade games, crash games, bingo, keno, and more.

If you accept a deposit-match bonus or risk-free bets, you’ll deposit funds into your account in USD. When you make wagers, it will be with real money.

When it’s time to cash out, you’ll withdraw them in USD, though you’ll need to clear wagering requirements before you can withdraw your winnings – and sometimes even possibly, your holdings.

Top Online Casino Bonuses for 2024

Types of Online Casino Bonuses for New Players

Welcome Bonuses

Welcome bonuses are offered by online casinos to entice new players to sign up and try out the platform.

The most common casino signup bonuses include no-deposit bonuses, first-deposit matches, and risk-free bets.

These bonuses are only offered to new players who have never created an account previously on the platform. Sometimes online casinos also prevent players from claiming welcome bonuses at sister sites, if they’ve created an account on another platform owned by the parent company.

No-deposit bonuses must be claimed upon new account signup; if you create an account without using the bonus code, manually claiming the bonus, or failing to use an affiliate link, you won’t be able to accept the bonus later.

With first-deposit bonuses, you must claim the bonus when making your first deposit. There’s no way to “retroactively” claim the bonus.

One example of a welcome bonus is the BetRivers Casino deposit bonus.

New players can get up to $500 in casino losses back in the first 24 hours after signing up when using the bonus code ODDSBONUS.

No-Deposit Bonuses

No-deposit bonuses offer players free fixed-amount account credits or free spins to try out games.

As the name suggests, there’s no deposit necessary to claim these bonuses. All you need to do is sign up for a new player account using an affiliate link or a bonus code and potentially manually claim the bonus.

Once qualifying actions have been completed, the bonus funds should be available in your account immediately.

If the bonus is a fixed amount, you can use those account funds to play qualifying games; if the bonus is for a set number of free spins or free plays, you can use those on specific games.

Right now, Bally Casino is offering the best no-deposit bonus of a $50 account credit to new players when signing up for an account.

Players in New Jersey or Pennsylvania can use this bonus to play over 400 games, including slots, table games, live dealer games, and more.

Free Spins

Another type of popular no-deposit welcome bonus is free spins.

Similar to the fixed dollar amount bonuses, you don’t need to deposit any funds into your casino account to claim this type of bonus.

But you won’t get a fixed dollar amount you can use to play any game. Instead, you’ll get a certain number of free spins that you can use on slot machines – or in some cases, specific slot machines.

Right now, one online casino offering such a welcome offer is PlayLive! Casino, which is offering new players in New Jersey and Pennsylvania a no-deposit bonus of 25 free spins.

You can use these spins on any slot machine, but you must then clear 20x wagering requirements on any money you win while playing your free spins.

Cashback Bonuses

Cashback bonuses, which are more commonly referred to as risk-free bonuses or bonus backs, are a type of casino deposit bonus.

These are commonly offered as both a casino signup bonus and a promotion for existing players.

With these bonuses, you must deposit funds into your casino account. You’ll then play these funds on qualifying games. If you incur net losses during a set time period, you’ll get your losses back in the form of an account credit.

Right now, FanDuel Casino is offering new players a great cashback bonus of up to $1,000 back in net losses on the first day.

Just deposit up to $1,000 into your casino account and play games. Any net losses you incur on that first day will be returned.

The best part is that there is only a 1x wagering requirement on this bonus, meaning you don’t need to play any returned funds before withdrawing them.

High Roller Bonuses

The bonuses with the highest dollar amounts are generally casino deposit bonuses. Online casinos don’t offer huge bonuses without requiring players to deposit funds.

The good news is that larger bonuses are usually offered as a welcome bonus. All you need to do to claim such a bonus is use an affiliate link or bonus code and create a new player account at a casino offering a big first-deposit bonus.

Borgata Casino is offering new players a high roller bonus of up to $1,000. This bonus is a first deposit match, so you’ll need to create a new player account, use the bonus code ODDSBONUS, and make a qualifying deposit to claim it.

Once you’ve created an account, make a deposit of up to $1,000. You’ll get a 100% bonus match, meaning you’ll get an additional $1,000 account credit added to your deposit.

You can use your funds to play slots and table games.

The bonus comes with 15x wagering requirements, so you’ll need to play $15,000 on eligible games before your winnings can be withdrawn.

Location-Specific Bonuses

There are many big-name online casinos that have online casinos in several states.

Casinos like BetMGM, BetRivers, and Caesars Palace, all have online casinos in different states.

Since these casinos are operated separately (with different land-based casino partners), each online casino may offer different bonuses.

One such casino is BetMGM, which offers a first-deposit match to players in New Jersey, Michigan, Pennsylvania, and West Virginia.

Yet, the bonus for New Jersey, Michigan, and Pennsylvania only offers a first-deposit match of up to $1,000.

The bonus for West Virginia players offers a first-deposit match of up to $2,500, plus a $50 casino bonus, and 50 bonus spins.

Make sure you sign up for an online casino account on the state platform where you plan to play.

If you live in Pennsylvania but travel to West Virginia, you can sign up for accounts in both states – but you can only play and use casino signup bonus funds in the state where you’re physically located.

Types of Online Casino Bonuses for Existing Players

In addition to casino welcome bonuses, online casinos also commonly offer promotions for existing players.

Though not as “generous” as welcome bonuses, these promotions encourage players to deposit funds during certain periods or play games they might not otherwise have tried.

The most common types of bonuses for existing players include reload bonuses, rewards programs, monthly and seasonal bonuses, and free spins.

Reload Bonuses

Reload bonuses allow you to get a deal when making an online casino deposit.

Similar to first-deposit matches, these bonuses give you a “boost” on deposits.

Although you might not get quite as large of a deposit-match percentage as you would with a first-deposit bonus, you can still increase your bankroll when taking advantage of reload bonuses.

Some online casinos offer a deposit-match percentage, and some offer a fixed dollar amount of credit to your account when you make a qualifying deposit.

Wheel of Fortune Casino sometimes runs an Everyone's A Winner promotion. When you opt-in during an active period and deposit $20, you’ll get a $10 account credit that you can play on slot games. 

Loyalty Rewards Program

Another way that online casinos reward existing players is through loyalty rewards programs.

When you sign up for an online casino account, you’re usually automatically enrolled in its loyalty rewards program.

With each qualifying play you make, you’ll earn points. The more points you earn on a monthly basis, the higher your tier level will be.

Each tier level has its own benefits, so you’ll be able to earn better and better rewards the more you play.

One example of an online casino with a great rewards program is the BetRivers iRush Rewards program.

You can see in the table below that this program offers 11 tiers of rewards. There are also special benefits associated with each level.

Refer-a-Friend Bonuses

Another way online casinos reward existing players is through refer-a-friend bonuses.

When you refer friends to your favorite online casino, using your unique referral link or code, you could get a bonus in the form of an account credit.

Your friend will need to sign up for a new player account, using your referral code or link. Then, they’ll probably need to deposit and wager a minimum amount of money for you to get your bonus credited.

Some online casinos offer casino signup bonuses to players who sign up using a referral link or code; some do not.

An online casino with a solid friend referral bonus is DraftKings Casino.

When your friends sign up using your unique referral QR code, make a minimum deposit of $25, and bet those funds, both you and your friend will receive a bonus.

The amount of the deposit will be matched, up to $100, by DraftKings, in the form of an account credit.

Weekly/Monthly Promotions

Many online casinos also offer weekly and monthly promotions on a rotating basis.

These types of promotions could include:

• Deposit bonus happy hours

• Wheel spins for prizes

• Weekend tournaments

• Community chat promotions

Stardust Casino advertises promotions that change every week.

To find out what types of promotions are currently available, log into your Stardust Casino account and click the “Promotions” page.

Since these offers vary from week to week and month to month, you’ll need to log into your account frequently to find out when they’re being offered – and which types of promotions are available.

Free Spins

Free spins are another popular promotion for existing players.

Online casinos offer free spins for new slot machines or to encourage users to play during slower gaming times.

Similar to free spin no-deposit welcome bonuses, you’ll usually need to opt in to receive this bonus as an existing player.

Sometimes online casinos send email notifications to let you know when these deals are offered, so you’ll want to opt in to email alerts if you’re interested in getting free spins.

They might also offer bonus spins when you make a minimum deposit.

One example of an online casino that has offered bonus spins in the past is FanDuel. During the holiday season, players who opted in and wagered at least $25 on Christmas slots received bonus spins on the Cleopatra slot machine.

Comparison of Online Casino Sign Up Bonuses

Best Online Casino Bonuses by Category

How to Choose The Best Casino Bonus

Wagering Requirements: The best online casino bonuses have lower wagering requirements, meaning you’ll only need to play your bonus funds 1x before you’re eligible to cash out winnings.

Bonus Amount: Obviously, the higher the bonus, the better. Look for online casino bonuses with high dollar amounts and low wagering requirements.

Game Contributions:If the games you want to play don’t contribute toward wagering requirements, the bonus won’t be worth much to you. Look for online casino promotions with lots of games that contribute 100% toward those requirements.

Validity Period:You’ll want as much time as possible to play your bonus and clear wagering requirements. Look for casino bonuses with the longest validity periods possible.

Eligible Games: You want to ensure the games you want to play are eligible with your bonus. Some bonuses only allow you to play certain games (or in some cases, one specific game). Make sure you can play games you’re interested in before accepting a bonus.

Withdrawal Methods: Most online casinos offer plenty of withdrawal methods, but you should always double-check to see if your preferred method is accepted on the platform. You’ll also want to check to see how long it takes to process withdrawal requests, so you’re not waiting for your winnings.

Reputation of the Casino: Most online casinos in the U.S. have similar reputations, mostly because they’re heavily regulated by states. But you should always read online casino reviews to ensure that the casino is reputable.

Casino Bonus Terms and Conditions

All casino bonuses come with terms and conditions, which you must satisfy before you can withdraw any winnings (or sometimes holdings).

It’s important to read bonus terms and conditions – as well as the platform’s terms and conditions – thoroughly before accepting any online casino bonus.

These terms and conditions will detail whether the bonus is fair, how long it could take to withdraw winnings, which games you’ll be able to play, and if you’re even eligible for the bonus in the first place.

The most common restrictions dictated in bonus terms and conditions include wagering requirements, game contribution percentages, bonus eligibility, time limits, and minimum deposits.

Wagering Requirements: All online casino promotions come with wagering requirements. This is the amount of times you need to play your bonus funds before they’re eligible for withdrawal.

The best online casino bonuses come with low wagering requirements

Wagering requirements are at least 1x and at legit online casinos in the U.S., can go up to 30x.

If you accept a bonus of $1,000 with a wagering requirement of 15x, you’ll need to wager $15,000 on eligible casino games before you can withdraw your winnings.

Game Contributions: Not all games contribute equally toward wagering requirements at online casinos. While most slots will contribute 100%, some slots, jackpot slots, and some table games, may not contribute at all (or a lesser percentage).

If you play $1,000 worth of bonus funds on an online casino game that contributes 25% toward wagering requirements, you’ll need to wager $60,000 to clear those requirements.

The best online casino bonuses are offered for games with high contribution rates.

Eligibility:Not every player is eligible to receive every casino bonus. To sign up for an online casino account, players must be at least 21 years of age, be physically located in the state in which they’re betting, and not be on any exclusion lists.

To accept a casino signup bonus, players must not have opened an account at that casino previously, and in some cases, they must not have previously opened an account at sister casino sites.

Time Limits: Every casino bonus comes with time limits. Online casinos set a limit as to how long you have to play your bonus – as well as clear wagering requirements.

The best online casino bonuses give you plenty of time to clear these requirements.

With some casino bonuses, you could have three days to clear wagering requirements (this is usually for small dollar amount bonuses). With others, you may have up to one week to 30 days to clear these requirements.

Time limits are always clearly posted in the bonus terms and conditions.

Minimum Deposit: To claim some bonuses, you may need to make a minimum deposit – this is common with casino deposit bonuses.

This amount is usually around $10, though it may vary depending on the bonus and the platform.

Some deposit bonuses are contingent on the initial deposit, including deposit-match bonuses (i.e. you’ll get the amount of your deposit matched if you deposit a minimum of $10); others simply require you to deposit the minimum amount to get a set bonus (i.e., deposit $10 to get a $50 bonus or 25 bonus spins).

Sometimes, to claim even a no-deposit bonus, you must have made a minimum deposit into your casino account within a certain time period.

Final Thoughts on Online Casino Bonuses

Online casino bonuses are a great way to boost your bankroll and – in some cases – try out an online casino platform without depositing any of your own funds.

Although casino signup bonuses offer the highest fixed dollar amounts and the most bonus spins, promotions for existing players can help you increase your account balances, too.

Before signing up for a new player account at an online casino, you should always check the welcome bonus offerings, especially since you’ll need to claim these upon signup.

Bonuses vary by each online casino, so it’s always important to target sites that offer the most ways to play the games you love the most.

And since all online bonuses come with restrictions, such as wagering requirements, game contribution percentages, and time limits, you’ll want to make sure that the bonuses you accept still allow you the freedom to play at your own pace.
