Reviewing the best online casino bonuses

I've reviewed the top operators to help you compare the best real money online casino welcome bonuses. You'll also find SBR-exclusive registration links and bonus codes to help point you in the right direction.

1. BetMGM online casino bonus - Best casino sign up bonus

By offering $25, BetMGM Casino is one of the only U.S. online casinos that features a no deposit bonus. After signing up, players will also be greeted with a 100% first deposit match up to $1,000 for using code SBR1000. If you’re in West Virginia, use the code SBR1000, and you'll get a 100% deposit match up to $2,500, a $50 no deposit bonus, and 50 bonus spins. 

Make sure to use the correct BetMGM Casino bonus code when prompted, depending on your state.

For a limited time, new users in all four states can instead choose a 100% deposit match up to $2,500 plus 100 bonus spins as their welcome bonus. Use our exclusive promo code: SBR2600.

BetMGM is my top pick thanks to the no deposit bonus. It's one of only two real money casinos currently offering a no deposit bonus as part of its welcome offer, setting it apart from the rest of the pack.

Follow our BetMGM Casino link, select your state (MI, NJ, PA, or WV), register, then verify your details, and the $25 (or $50) will be automatically credited to your account. To receive the 100% match bonus, you must deposit at least $10.

2. Caesars Palace online casino bonus - Biggest welcome bonus

Caesars Palace Online Casino offers one of the largest deposit-match bonuses in the regulated U.S. market. Additionally, it gives players a substantial amount of points for its coveted loyalty program, Caesar's Rewards, which is why we ranked it as one of the best online casino bonuses in the United States.

New U.S. customers from MI, NJ, PA, and WV can claim a $10 Sign-Up Bonus + 100% Deposit Match up to $1,000 + 2,500 Reward Credits . You will receive the no deposit bonus after registering and using the Caesars Palace Casino promo code SBRLAUNCH. The Reward Credits will become available only after wagering at least $25 on casino games during the first seven days after registration.

Caesars Palace earns high marks for its layered welcome offer. Getting a sign-up bonus, a deposit match, and Reward Credits is more valuable than you'll find at most other operators.

You will also have seven days to meet the bonus offer wagering requirements.

3. DraftKings online casino bonus - Best for exclusive games

DraftKings Casino has one of the best dollar-for-dollar welcome bonuses among U.S. online casinos, Bet $5, Get 1,000 Flex Spins without a DraftKings Casino promo code.

The offer requires a minimum wager of $5 and the 50 daily spins are issued upon login for 20 days. They expire 24 hours after choosing a select game.

In addition to a solid welcome bonus, DraftKings Casino is a great destination if you're looking for a variety of games to play. DraftKings has a bevy of exclusive titles, including Shiver Me Spinners, Chompin Cash, One and Out, and many more.

Additional online casino bonuses after sign-up

Welcome bonuses are a great way to get in the door, but the best online casinos know that existing players need promos too. Here are some of our favorite casino bonuses beyond the welcome offer from the top operators.

How to choose the best online casino bonus

Picking the best online casino bonus requires similar research to picking the best sportsbook promos. Below, we offer a couple of important tips for choosing the best online casino bonus for you.

Pick a bonus based on your deposit amount

If you’re a high roller willing to deposit over $1,000, you should pick a casino with a large deposit match bonus, like the offer from Caesars Palace Online Casino. If you just want to start with a smaller deposit, it might be more prudent to opt for a promotion like DraftKings'.

Mind the wagering terms

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, such as game eligibility, wagering contributions, and time limits. 

It's always crucial to check whether there are any restrictions on which casino games are eligible for a bonus. It's not uncommon for some games to be ineligible, with bonuses restricted to featured games only.

Check the bonus for your specific state

Online casinos often have different bonuses for different states. Read the fine print so you know exactly what bonus is available to you and how to claim it. For example, BetMGM offers a larger deposit match to players in West Virginia than to those in Michigan, New Jersey, and Pennsylvania.

Find bonus codes

Bonus or promo codes unlock offers that aren’t always advertised on an operator’s main landing page. These often include bigger deposit matches, free spins, or a no deposit bonus. The good news is you don’t need to scour the internet to find them. We regularly update and verify the latest working codes right here at SBR, so you can quickly access the best available offers.

You can use more than one bonus

There’s no restriction on how many online casinos you can sign up for at the same time, which means you’re not limited to just one welcome bonus. Many players take advantage of this by claiming multiple online casino sign up bonuses at different sites. This approach can extend your playtime and increase your chances of finding the platform and games that suit you best.

Beware offshore or unregulated platforms

I'd encourage you to stick with licensed and regulated online casinos in your state or jurisdiction. Licensed operators are required to honor their promotions, provide fair gameplay, and process withdrawals reliably. Offshore or unregulated platforms may advertise attractive bonuses, but they often come with unclear terms, delayed payouts, or added risks that you should look to avoid.

How to claim your casino bonuses online

Our step-by-step guide will help you start using your new online casino bonuses as quickly as possible. First, check the full bonus terms and conditions before registering. For example, at Caesars Palace, you only have 7 days to use your bonus after registering and making a deposit. Additionally, every online casino will require you to meet the wagering requirements for your bonus funds before they can be redeemed.

1. Choose your state and register an account with the required details. Usually, you'll be prompted to enter your name, DOB, and SSN, etc.
2. Use our exclusive SBR bonus code when prompted. This usually happens during registration or when making a deposit. At Caesars Palace, the promo code is SBRLAUNCH.
3. Complete the first deposit while keeping the minimum deposit limit and maximum bonus amount in mind. At Caesars Palace, the minimum deposit is $10. It's always important to know what the minimum deposit and maximum bet amounts are at a particular casino before you decide if it's the right one for you.
4. Follow the casino’s instructions to activate the bonus and start playing. If we've provided a bonus code, enter it. If not, fulfilling the required deposit or bet usually activates the bonus automatically.

Types of online casino bonuses

We’ve broken down the most common online casino bonuses to help you understand which offers are actually worth your time and fit your gaming style best. Below, you’ll find a guide to the different types of bonuses you’re likely to encounter at top online casinos, and how each one can impact your play.

Deposit casino bonuses

Casinos that offer bonuses for players who make a deposit are usually best suited for those who are comfortable making a larger initial investment.

Both BetMGM and Caesars are offering new users a 100% deposit match up to $1,000.

No deposit bonuses

No deposit bonuses are incentives given to new players who register at an online casino. These offers allow you to collect bonus bets just for signing up. The bonus usually becomes available immediately after you sign up and verify your details.

Free spins bonuses

Free spins are a great way to get into playing video slots. If you get lucky, you can win plenty of bonus credits. They're usually available on specific video slots, and often for just one particular game.

Right now, Golden Nugget Casino is dishing out 500 spins over 10 days on Huff N' Puff games for new customers. 

Refund or loss back bonuses

You can play up to a certain amount, as the casino will refund you in the form of a bonus. You only get this bonus if you lose, and there are no rewards for just completing a deposit.

Bet and get bonuses

These are an easy way to accumulate bonus funds, as you only need to make a small wager. They're rarer and smaller than other bonus types (usually up to $100).

FanDuel has an ongoing promotion that awards users 500 bonus spins, plus a $40 casino bonus after a deposit of at least $10.

Daily login bonuses and promotions

Many operators offer daily login casino bonuses and promotions to keep players sticking around and help them top up their bankroll. It's always important to note when a daily bonus resets and if you're eligible to combine it with any other offers.

Weekly and monthly casino bonuses and promotions

Many casinos honor their regular customers by issuing them bonuses on a weekly or monthly basis. Monthly bonuses are often one of the perks of being a member of a casino’s loyalty program.

High-roller bonuses

Making large deposits will surely get you noticed by the casino, which may offer exclusive high-roller deals and perks. Players recognized as high rollers may be invited to special events and receive bespoke gifts from the casino.

For example, Caesars Palace offers a maximum bet of $20,000 on some of its games, including Live Dealer Blackjack. Caesars' rewards program is also very beneficial for players who are drawn to wagering larger amounts.

Game-specific bonuses

Some bonuses are valid only for a particular game or game type. Free spins are the most common game-specific bonus, often only available on select video slots.

Horseshoe Online Casino currently has a weekly reload bonus available of up to $15. It requires a $10 minimum deposit with 2x wagering on slots games, 4x on video poker, and 10x on table games. This means you must wager your bonus amounts twice on slots, four times on video poker, and 10 times on table games before you're eligible to withdraw.

Mobile casino bonuses

Online casinos sometimes offer special mobile bonuses to incentivize players to download their mobile casino apps. You can only claim a mobile bonus if you download and log in through the casino’s app. Apps like BetMGM will often reward mobile use with loyalty/MGM Rewards benefits.

Meanwhile, Caesars Palace launched its Remote Reels, connecting mobile app users to live slot gameplay from the casino floor at Tropicana Casino in Atlantic City, New Jersey.

Best games to play with your online casino sign-up bonus

Most casino bonuses can be used across a wide variety of games from any of the best payout online casinos. Often, promotions are designed for specific titles, such as slots, table games, or live dealer games. Be sure to check things like Return to Player Rate (RTP) and wagering requirements with particular games to ensure you maximize your online casino sign-up bonus. It's important to note that game types vary in how many times bonus funds must be played through at most casinos. 

We've broken down the various types of games you're likely to encounter with your bonus.

Online slots

Slots are the most common type of game you'll encounter with your bonus as they're fairly straightforward, have quick redemption times, and usually fully count toward any wagering requirements. Many online casinos offer free spins bonuses tied to some specific online slots games. If you're looking for the easiest way to use your bonus, slots are the way to go.

Online table games

Many operators offer a variety of table games, including blackjack, roulette, baccarat, and video poker. Unlike slots, some casinos tend to shy away from including table games in connection with any promos or bonuses. They also tend to have a higher wagering requirement than slots titles. 

Live dealer games

Live dealer games are a more interactive option than online table games, as they let you play with real dealers and chat with other players. Most online casinos offer a somewhat limited array of live dealer games, which can have lower contribution rates than other game types.

Game show games

These are similar to live dealer games, but mix in elements you might find on a television show. They often feature bonus rounds, spinning wheels, and large multipliers. 

Progressive jackpots

Most online casinos offer progressive jackpot slots where the prize increases until someone wins. Unfortunately, most casino bonuses tend to shy away from these progressive jackpots by limiting game eligibility or wagering amounts.

Exclusive games

Most major online casinos offer a variety of exclusive games on their platforms. Before you try any of these, make sure they're eligible titles for your bonus and have reasonable wagering requirements.

Best US casino bonuses summary

Use the following table as a reference, so you can pick the bonus that best suits your style of play.

Best casino bonuses by state

Online casinos offer different bonuses to players depending on the state in which they sign up. The table below shows how different the world of legal online casinos and sweepstakes is from state to state.

Not in a legal casino state? There are sweepstakes and social casinos available in other states too.

You can still find most sweepstakes options in Texas, Florida, and Ohio online casinos.

However, many states have started to crack down on sweepstakes operators, banning them altogether in many instances. Both New York online casinos and California online casinos only offer social casino options at this time as a result of legislation in each state.

How we rate & review the best online casino bonuses

To create our lists of the best casino bonuses, 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 featured on this page must comply with stringent state regulations. This includes ensuring excellent player safety and protecting 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 a lower financial commitment and, therefore, provides better overall value.

Wagering & playthrough requirements

Playthrough requirements essentially tell us how hard it is to convert the bonus into real money. 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 bonus's validity period can range 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.

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.
