Top casino sign-up bonuses reviewed

Editor's Note: Casino bonus mentions are for US residents in legal casino markets only.

Claiming a welcome bonus is one of the very first things you’ll do after joining an online casino or best sportsbook promos. They often require a minimum deposit (aside from rare no-deposit bonuses) and a promo code (if applicable).

This table will help you better compare the best online casino sign-up bonuses and promotions, complete with our exclusive registration links and bonus codes.

Caesars Palace Online Casino 

Deposit Match up to $2,500

Terms and Conditions Apply

Sportsbook Review may receive advertising commissions for visits to a sportsbook betting site. 21+. Gambling can be addictive, please play responsibly

Caesars Palace Online Casino offers the biggest deposit match bonus in the regulated U.S. market. Additionally, it gives players a substantial amount of points for its coveted loyalty program, which is why we ranked it this year’s best online casino bonus in the United States.

New U.S. customers from MI, NJ, PA, and WV can claim a 100% first deposit match up to $2,500 and 2,500 Reward Credits. You will receive the deposit bonus after making a deposit of at least $10 and using the promo code ‘SBR2500’ during sign-up. Meanwhile, the Reward Credits will become available only after wagering at least $25 on casino games during the first seven days after registration.

You will also have seven days to meet the bonus offer wagering requirements, which are 15x on video slots, 30x on video poker, and 75x on all other games except craps. These playthrough requirements seem a little steep compared to some of the other offers you’ll see down this list, but the sheer scope of the promotion ensures it stands out from the crowd.

FanDuel Casino 

Deposit $10, Get $20 In Site Credit & Play It Again $1,000

New customers. Deposit $10, get up to $1,000 back in bonus funds + $20 site credit. Funds and credit expire after 7 days.

Sportsbook Review may receive advertising commissions for visits to a sportsbook betting site. 21+. Gambling can be addictive, please play responsibly

Signing up to FanDuel Casino from MI, NJ, PA, or WV will make you eligible for $20 in site credit and up to $1,000 back in bonus funds. There’s no promo code you need to use, so just follow our links, register a new account, and deposit at least $10.

This is another very attractive welcome offer with two components. You’ll get the $20 in site credit regardless of the initial deposit amount, as long as it's $10 or more. In addition, the ‘Play It Again’ bonus covers your first-day losses (first 24 hours) up to $1,000.

The best part of this bonus, and all other bonuses in FanDuel Casino, is that it comes with wagering requirements of only 1x, giving you a realistic chance of turning the bonus funds into withdrawable cash. The bonus expires seven days after being credited to your account.

DraftKings Casino 

Play $5, Get $50 in Casino Credits Instantly

Terms and conditions apply

Sportsbook Review may receive advertising commissions for visits to a sportsbook betting site. 21+. Gambling can be addictive, please play responsibly

DraftKings casino arguably has the best dollar-for-dollar welcome bonus among U.S. online casinos, with a $5 wager earning you $50 in Casino Credits.

You can place the qualifying wager on any of the DraftKings Casino games within seven days of creating a new account and will receive the bonus regardless of the wager’s outcome. The reward will appear in your account immediately (or within 72 hours in case of technical difficulties).

The $50 in Casino Credits carry a 1x rollover and must be used within seven days. You can use the bonus to play all the games at DraftKings Casino, except live dealer games.

BetRivers Casino 

100% Refund Up To $500

Terms and conditions apply

Sportsbook Review may receive advertising commissions for visits to a sportsbook betting site. 21+. Gambling can be addictive, please play responsibly

If you’re located in MI, NJ, or WV, BetRivers Casino will cover your net losses up to $500 on your first day. Delaware players can receive a refund of $250, while players from Pennsylvania can claim a 100% deposit match up to $250 instead.

Regardless of where you access BetRivers Casino from, make sure to use the promo code ‘SBRBONUS’ when making your initial deposit. The minimum deposit is $10.

Once the payment is through and you start playing, the net losses you sustain during the next 24 hours will be returned to your bonus balance within 72 hours up to the maximum of $500. The refunded bonus carries a 1x playthrough.

This is essentially a less generous version of the FanDuel Casino bonus, which covers your losses two times over and gives you an extra $20 in casino credits immediately upon deposit.[BP2] 

BetMGM Casino 

100% Deposit Match up to $1,000

Terms and conditions apply

Play Now

Sportsbook Review may receive advertising commissions for visits to a sportsbook betting site. 21+. Gambling can be addictive, please play responsibly

BetMGM Casino is one of the few online casinos in the U.S. that offer a no-deposit bonus. Newly registered users get $25 on the house before laying down their first payment, plus a 100% first-deposit match up to $1,000. Better yet, if you’re from West Virginia, you will get a 100% bonus up to $2,500, $50 on the house, and 50 bonus spins.

Once you click on our link and head over to BetMGM, select your state (MI, NJ, PA, or WV). Create an account, verify your details, and the $25 (or $50) will be automatically credited. To receive the 100% match bonus, you must deposit at least $10. Make sure to use the promo code SBRBONUS when prompted.

The wagering requirements are 1x on the no-deposit bonus and 15x on the deposit bonus, but keep in mind that not all games contribute to wagering (see the list of excluded games on the bonus T&Cs page).

bet365 Casino 

100% Bonus up to $1,000

Terms and conditions apply

Play Now

Sportsbook Review may receive advertising commissions for visits to a sportsbook betting site. 21+. Gambling can be addictive, please play responsibly

Similar to Caesars Palace and BetMGM, bet365 Casino offers a 100% deposit match for its first-time customers. However, because the bonus' maximum amount is smaller and the rollover is higher, we ranked bet365’s welcome offer slightly lower on our list.

The maximum bonus you can receive is $1,000, and the wagering requirements are 20x on the deposit plus the bonus amount (as opposed to 15x in Caesars Palace and BetMGM). You have 60 days to wager the bonus, and you can wager it on all games, excluding live dealer games, baccarat, Quantum Roulette Instant Play, and virtual sports.

To receive the bonus, use our promo code ‘SBRBONUS’. Please note that bet365 Casino currently only operates in New Jersey.

Betway Casino 

100% Deposit Match up to $1,000

Terms and conditions apply

Sportsbook Review may receive advertising commissions for visits to a sportsbook betting site. 21+. Gambling can be addictive, please play responsibly

Rounding out our top list is the Betway Casino bonus, which grants first-time PA and NJ players 100% and 50% welcome bonuses, respectively, up to $1,000.

The minimum deposit is $10, and the playthrough requirements are 25x for PA and 30x for NJ players, but you can only wager the bonus on video slots. The playthrough must be completed within 30 days of receiving the bonus funds.

How to choose the best online casino bonus

Now that we have laid out the best online casino bonuses in the U.S. and uncovered their most important terms, it should be easier for you to choose your favorite. But if you’re still uncertain as to which bonus is best for you, we hope that some of these pointers will nudge you in the right direction:

• Pick a bonus based on your deposit amount: If you’re a high-roller willing to deposit $1,000 or more right from the get-go, you should pick a casino with a large deposit match bonus, like the $2,500 on offer from Caesars Palace Online Casino. On the other hand, if you just want to dip your toes in the water with a small $10 or $20 deposit, it’s wiser to opt for something like the “bet $5, get $50” promotion on DraftKings.

• Mind the wagering terms: Naturally, the lower the wagering requirements, the easier it will be for you to clear the bonus. However, you should also pay close attention to other wagering rules, like game eligibility, wagering contribution, and time limits.

• Check the bonus for your specific state: Online casinos often have different bonuses for different states. For example, joining Betway Casino from PA will grant you a solid 100% first deposit bonus, but NJ players only get a 50% bonus with stricter terms.

• Find bonus codes: Bonus or promo codes sometimes lead to more extensive and exclusive bonuses. Luckily, you don’t have to go anywhere to find these codes, as we have our own right here at SBR.

• You can use more than one bonus: There’s no limit to how many online casinos you can join from your state, so instead of just picking one casino and using one welcome bonus, you can opt for several and play through them one at a time.

• Beware offshore or unregulated platforms: Plenty of international or offshore online casinos will happily take your money. However, there are many with dismal reputations for fair play and actually letting you withdrawal any winnings. Stick to the online casinos that are licensed in your state in order to have confidence that you'll receive your welcome bonus, as promised.

Types of online casino offers

Online casinos reward players in various ways, from welcome bonuses incentivizing newcomers to VIP programs designed for loyal customers. Understanding the differences between these promos and learning their benefits and disadvantages is essential to getting the most value for your money — and avoiding potential pitfalls.

The following table contains some of the most popular welcome offers among U.S. casino sites and outlines their key characteristics.

Welcome Casino Bonuses 💰

All online casinos offer welcome bonuses to attract new players. They can take multiple forms, with first-deposit match bonuses being the most prevalent type.

• You receive the bonus as soon as you complete your first payment.
• The minimum deposits are usually just $10.
• First-deposit match bonuses are often between 50% and 100%, with max amounts ranging from $500 to $2,500.

No-Deposit Casino Bonuses 🤑

No-deposit bonuses are small incentives given to new players who register at an online casino. They are quite rare.

• The bonus becomes available immediately after you sign up and verify your details.
• This is an excellent way to scope things out on a casino site without taking risks.
• They often come in small amounts between $10 and $50.

Monthly Casino Bonuses and Promotions 📆

Many casinos honor their regular customers by issuing them bonuses on a weekly or monthly basis.

• Getting a bonus every month helps maintain your bankroll.
• Monthly bonuses are often one of the perks of being a member of a casino’s loyalty program.
• The longer you play, the better the monthly bonuses become.

High-Roller Bonuses 🎲

Making large deposits will surely get you noticed by the casino, which may offer exclusive high-roller deals and perks.

• A high-roller is a player who regularly deposits and stakes big money, typically in the thousands.
• Players recognized as high-rollers may get invited to special events and receive bespoke gifts from the casino.
• A high-roller status may include added benefits like a dedicated account manager or personalized support.

Game-Specific Bonuses 🃏

Some bonuses are only to be used on a particular game or game type.

• Free spins are the most common game-specific bonus, often only available on select video slots.
• Some casinos have bonuses for live dealer games, like live casino cashback.
• Game-specific bonuses are usually made available when a casino wants to promote its new lineup of games.

Mobile Casino Bonuses 📱

Online casinos sometimes offer special mobile bonuses to incentivize players to download their mobile apps.

• You can only claim a mobile bonus if you download and log in through the casino’s app.
• This is an excellent bonus if you prefer playing casino games on smartphones or tablets.
• Installing the app takes minutes, costs nothing, and usually doesn’t take up too much storage.

State-Specific Bonuses 📍

Online casinos may offer different bonuses to players from various states for multiple reasons.

• A player from New Jersey may get a bigger bonus than one from Pennsylvania, and vice versa.
• Sometimes, the type of bonus can be state-specific, not just its amount.
• You don’t need to be a resident of a given state to claim a bonus; you just need to be physically present in that state during sign-up.

7. Follow the casino’s instructions to activate the bonus and start playing. Best of luck!

Casino bonuses for existing customers

Bonuses for first-time players at real money online casinos are often the biggest and provide the best value, which makes a lot of sense considering casinos use them to attract new customers. But no matter how generous they are or whether you turn them into real-money winnings, sign-up bonuses will eventually run out, usually within a few weeks or a couple of months.

That’s why it’s crucial to pick a casino that not only has an attractive welcome offer but regularly supplies various promotions to players who have outgrown their ‘new customer’ status. These promos come in many shapes and sizes, with the most common ones being:

• Reload bonuses: A bonus similar to a first-deposit offer, only made available to subsequent depositors.

• Friend referrals: Inviting a buddy through a referral link may result in a bonus for both of you.

• Periodical bonuses: Regular players can receive bonuses once every week or month.

• Game tournaments: Participating in tournaments and ranking high on the leaderboards usually comes with a reward in the form of a bonus.

• Loyalty programs: Casinos with loyalty programs have a point system in place. The more points you win (usually by making deposits and wagering), the higher your status becomes, which leads to special loyalty bonuses and other perks.

How we rate & review the best online casino bonuses

We created our best online casino bonuses list after much research and consideration. Our panel of experts carefully reviewed each welcome offer, examining its terms and determining its actual value.

Our research focuses on the following key areas.

Safety & Security

The casinos promoted on this page must abide by stringent state regulations, which include ensuring the utmost safety of all players and the confidentiality of their sensitive information.

Bonus Type & Amount

The simplest way to compare two bonuses is by looking at their face value. Of course, we also must consider the bonus type. Maybe a first-deposit bonus of up to $1,000 is larger than a ‘Bet $5, get $100’ offer, but the latter requires less financial commitment from the player and is, therefore, better overall value.

Wagering & Playthrough Requirements

These are the most important bonus terms, as they essentially tell us how hard it is to convert the bonus into real money. Of course, the lower the wagering requirements, the better.

Games & Other Restrictions

Looking into eligible games is important, as some bonuses may seem easy to clear, only for you to find out that all the high-RTP games have been excluded from the full wagering contribution.

Validity & Expiry Period

We appreciate a casino giving players enough time to claim, use, and clear a bonus. Depending on the bonus type and the casino’s generosity, the validity period of a bonus can be anywhere from a few days to a couple of months.

Cap on Winnings

Another “hidden” term that can be devastating to your casino bonus hopes is the cap on winnings. It’s great when a casino doesn’t impose any maximum limit on your bonus wins, but they’ll usually restrict them to a certain amount, making sure you don’t get away with being too lucky.

Legitimacy & Legality

It is vital to establish an online casino's safety and legality before we examine its bonuses. We only scan platforms licensed in one or several states that have legalized online casino gambling.

Legal online gambling in the US

Legal online casinos in the U.S. are currently limited to just seven states, including Delaware, Connecticut, Michigan onlne casino, NJ online casino, PA online casino, Rhode Island, and WV online casino. To play, you don’t necessarily have to be a resident of these states but must be physically located inside their borders.

This doesn’t mean that players from other states are completely devoid of options. Namely, sweepstakes casinos are allowed to operate in nearly all U.S. states by offering online gambling in a non-direct way. You can only win real money prizes on these platforms by purchasing, wagering, and then redeeming virtual currency. This unique set-up is not considered real money gambling by most states and is currently the sole legal option for enjoying online casino games in the majority of the country.
