The Best Online Casino Bonuses in the US for 2025

My Top 5 Online Casino Bonuses

All our top-rated US online casinos are strong in the bonus department. In fact, they’re strong in all areas, including games, payments, and customer support.

So, to avoid stating the obvious, I’ll focus on each casino’s bonus offers and features. This will help you find the right sites and bonuses for you.

1. BetMGM Casino - $25 No Deposit Bonus + 100% Deposit Match Up to $1,000

• Bonuses available at BetMGM Casino: No deposit bonus, welcome bonus, loyalty rewards, free-play giveaways, bonus spins, and bonus drops.

BetMGM Casino is the best bonus online casino for no-deposit offers. While wagering requirements do apply, BetMGM consistently provides more no-deposit bonuses and giveaways than other US online casinos.

It all starts with the welcome bonus. Using the BetMGM Casino bonus code WSNCASINO during registration gets you $25 on the house ($50 and 50 bonus spins if you are in West Virginia). Once you choose to deposit, you’ll get a 100% deposit match up to $1,000 ($2,500 in West Virginia).

From there, you can enter daily prize draws. In 2025, a standout has been the Family Feud Daily Round. I also like the arcade claw bonus offer, which gives you a chance to literally pick up prizes worth up to $5,000.

Finally, I can’t ignore BetMGM Casino’s loyalty program. What’s unique about this program is that it evolves with the seasons. For example, in the run-up to Christmas, the Holiday Gift Shop gave players a chance to swap points for festive gifts, including jewelry and tech.

2. FanDuel - Deposit $10 and get 500 Bonus Spins & $40 In Casino Bonus

• Bonuses available at FanDuel Casino: No deposit bonus, welcome bonus, cashback, free spins, and reload bonuses.

FanDuel is one of the best-known brands in the US iGaming space. Originally starting as a daily fantasy sports operator, it now also runs its own online casino. New players who join FanDuel Casino can take advantage of a special welcome offer, which includes 500 bonus spins and $40 in bonus credits.

To claim this offer, simply sign up using our sign up link and make a first deposit of at least $10. In my opinion, this is a fantastic offer for casual players, as it provides a lot of value without requiring a big investment.

The bonus spins are credited to your account over ten days, with 50 spins arriving each day. These bonus spins can be used on any slot, including the recent addition to FanDuel: the Huff N’ More Puff slot.

I really like this format. Online casino promotions that continue to unfold after you’ve initially signed up make the experience more engaging.

On the other hand, the $40 in bonus credits is credited to your account right away, and you can use it on any game you like. The bonus spins expire five days after they’re credited, while the bonus credits expire after seven days.

The great thing about this casino bonus offer is that both the free spins and the casino bonus have a 1x playthrough wagering requirement. Meaning, you only have to wager them once, and you get to keep all your winnings.

Once you've claimed the welcome bonus, be sure to explore FanDuel’s full promotions page, which includes daily jackpots, boosted spins, and a referral bonus.

3. Caesars Palace Online Casino - $10 Sign-Up Bonus + 100% Deposit Match up to $1,000

• Bonuses available at Caesars Palace Online Casino: No deposit bonus, welcome bonus, loyalty rewards, leaderboards, and slot spins giveaways.

Caesars welcomes you with two welcome bonuses. The first is a $10 no deposit bonus that’s released once you successfully create an account using the promo code WSNLAUNCH. After that, you’ll receive a first deposit match bonus worth up to $1,000. 

You’ll need to wager 1x to release your no deposit bonus and 15x to get your deposit bonus. The only other caveat you need to know, and it’s one I don’t love, is that you can only clear your bonuses by playing selected slots. I often tell newbies to play slots because they allow you to clear bonuses efficiently, but I also like being given a choice. 

Beyond its welcome bonus, Caesars Palace Online Casino does a great job of creating unique free spins bonuses. It offers all the usual promotions, like deposit bonuses, but it mixes things up with draws. The best example of its prize draw was the 100,000 bonus spins giveaway.

Bonus spins are great, but they’re only suitable for slot players. That’s why I want to mention Caesars Rewards. This loyalty program is suitable for everyone, and not just because you start earning points when you wager $5 or more.

Caesars Palace Online Casino runs a variety of promotions that give you more loyalty points, such as the 5x Reward Credit Multiplier for playing the Game of the Week. You can also earn points for spending money at Caesars' 50+ land-based casinos. This means you’ve got plenty of ways to earn online casino bonuses, hotel discounts, free meals, luxury vacations, and more.

4. bet365 Casino - Match Bonus up to $1,000 + Up to 500 Spins

• Bonuses available at Bet365 Casino: Welcome bonus, spins, missions, free prize giveaways, and live dealer casino bonuses.

bet365 Casino’s promo team understands the value of engagement. By giving you reasons to stay active, the team is simultaneously giving you more ways to earn extra credits. The first example of bet365 Casino’s penchant for promotional engagement is the welcome bonus.

Or, to be precise, two welcome bonuses: a $1,000 first deposit match or 10 days of spins. Both offers are activated when you deposit at least $10. The match bonus has a 30x playthrough, but free spin wins are paid in cash. 

What’s fun about the spins is that you never know what you’re getting. Basically, you tap the red, yellow, or blue button ten times in 20 days. Each button reveals between five and 50 spins.

bet365 Casino also keeps you engaged with Slots Missions that require you to complete challenges. Each of the four challenges you complete unlocks a certain number of bonus spins. Complete all four, and you get 60 spins.

The other ongoing offer designed to keep you engaged is Cash Cascade. This promotion sees you earn raffle tickets each time you wager $5. The more tickets you earn, the more chances you’ve got to be selected in the $5,000 prize draw.

5. Hard Rock Bet - 200 Bonus Spins + 100% Cashback up to $1,000

• Bonuses available at Hard Rock Bet: Welcome bonus, loyalty rewards, happy hour offers, reload bonuses, sweepstakes draws.

Hard Rock hits a high note with its opening track (aka offer). New customers get 100% cashback up to $1,000 (1x playthrough) and 200 bonus spins. 

I’ve seen cashback bonuses before, and they’re a great way to offset initial losses. But rarely have I seen bonus spins with cash payouts added to the mix. That’s why I'm happy to vibe with Hard Rock Bet’s Casino welcome bonus. 

Hard Rock Bet is an online casino that values loyalty. I could, of course, say that about any casino with a loyalty program. However, Hard Rock Casino stands out in this regard because its regular bonuses improve in line with your status.

For example, Hard Rock Bet Casino offers weekly reload bonuses. The standard offer is a 25% deposit bonus with a 15x playthrough. As your status improves, the multiplier increases, and the playthrough decreases. At the top end, you get a 100% reload bonus with a 1x playthrough.

Earning points also gives you access to a weekly sweepstakes draw. Again, your potential value is determined by the number of points you’ve earned. More points give you more chances to win one of 500 prizes. Finally, my pro tip for all you bonus hunters out there is to play during Happy Hour. This will give you maximum earning potential for the least effort.

All US Online Casino Bonuses & Promos December 2025

The latest US online casino promo codes are always changing, which is why we keep an eye on the market at all times. Below are all the available online casino bonuses in the US you can claim right now.

Types of Casino Bonuses

I know that casino bonuses can sound confusing to new players, particularly when it comes to wagering requirements. I too was confused when I first started out. 

I didn’t know how to claim casino bonuses, whether I could withdraw site credit, or what offers to look out for. It took a while, but I learned. 

Now, to save you time, I’ve condensed everything I know about every type of casino bonus currently available in the US.

1. Deposit Match

Match bonuses double or sometimes even triple your starting deposit. For example, if you deposit $50, you’ll receive $50 worth of bonus credit.

The majority of online casino welcome bonus offers in the US are deposit matches. This helps distinguish them from reload bonuses that are worth a percentage of your deposit’s value. 

You’ll often see these bonuses called 100% deposit match offers. The “100%” refers to the fact that your bonus is worth 100% of your deposit’s value, rather than an amount more commonly associated with reload offers, such as 25%.

2. No Deposit Bonuses

A no deposit casino bonus is exactly what it sounds like: a reward credited to your account without requiring you to add any funds first. While many of the best online casino promotions are unlocked by deposits, these offers are given for different reasons, such as simply creating an account.

For example, an online casino sign-up bonus is released once you’ve completed the registration process. In other words, you’re being rewarded for signing up to a new online casino.

However, keep in mind that no deposit bonuses still have wagering requirements. Additionally, to withdraw any winnings, you will usually need to make a small deposit to verify your payment method. The upside, of course, is that you have a good reason to do so.

3. Bonus Spins

Bonus spins allow you to play selected slots without spending a cent. The beauty of these bonuses is that spins are the same as real-money wagers. This means you’re playing for cash prizes.

In most cases, the money you win from bonus spins will be paid in site credit that can’t be withdrawn until you hit a playthrough target. The best casino bonus offers in this category pay prizes in cash that you can withdraw instantly.

Bonus spins have a set value (usually 10 cents or 20 cents) and can only be used on selected slot games.

4. Cashback Bonuses

A cashback casino bonus is essentially a refund on your bad luck, returning a percentage of your net losses over a specific period. Losses are a natural part of casino gaming, but these promotions act as a safety net to help you recoup some of those funds.

The refund is calculated on your net loss (total wagers – bonuses – wins), and in most cases, it is paid out weekly.

The reason cashback is arguably the best casino bonus is that rebates are often paid as site credit. Unlike standard bonuses, site credit usually has a 1x wagering requirement. This simply means you use it to play a game once, and anything you win becomes real cash you can withdraw.

5. Special Bonuses

Special bonuses are unique offers that fall outside the standard categories. Instead of being available year-round, these promotions are usually tied to specific celebrations or moments in time and include a mix of different casino bonuses.

While casinos can get creative with these, the two most consistent types you will encounter are Seasonal Bonuses and Birthday Bonuses.

Seasonal Bonuses

The lead-up to holidays and major cultural events is a good time for casino bonus hunters. The theme of these promotions matches the event.

For example, if it’s the festive period, a US casino operator might run a month-long Advent calendar promotion that gives away new bonuses every day.

Christmas, Easter, and Thanksgiving are the best times to collect seasonal bonuses. Every top-rated US casino has new offers during these times, so don’t be afraid to shop around for good sesonal deals. You can find the latest promotions for specific holidays here:

• Thanksgiving Casino Bonuses

• Black Friday Casino Bonuses

• Christmas Casino Bonuses

• Easter Casino Bonuses

• St. Patrick's Casino Bonuses

• Halloween Casino Bonuses

Birthday Bonuses

One of the perks you often get for climbing the ranks of an online casino’s loyalty program is a special online casino birthday bonus. In most cases, you’ll receive a few free spins or a reload bonus.

The best bonus online casino sites may also give you wager-free rewards, which means any prizes you win get paid in cash.

You must verify your identity to use legit US online casinos. Therefore, it’s not a good idea to lie about your date of birth just to get an instant bonus. Be truthful, and you’ll get a reward when the time comes.

Things to Watch for When Claiming a Casino Welcome Bonus

Welcome offers are the top online casino bonuses when it comes to one-off payments. That’s why online casino welcome bonuses are so important.

With so much potential out there, it’s important to understand how the best online casino welcome bonus offers work.

I’ve claimed thousands of dollars through these casino promotions, and you can do the same by following these tips:

1. Make Sure You’re a Newbie

You can only claim welcome bonuses if you’re a new customer. That means you haven’t previously created an account with any site connected to the casino.

The most common mistake I’ve seen people make is thinking they’re a new customer when they’ve already got a sportsbook account.

Let’s say you joined FanDuel Sportsbook in 2024. It’s now 2025, and you want to play some casino games. You can’t open a new account at FanDuel Casino and claim the welcome bonus because you’re already a customer.

So, if you’re trying to claim an online casino sign-up bonus, make sure you’re a completely new customer. 

2. Does Your Deposit Qualify?

Deposits need to meet or exceed a minimum limit to qualify for bonuses. The best casino welcome bonus offers usually have a minimum deposit of $10, but there are low minimum deposit casinos in the US that only ask for $5.

You should also check that your chosen casino payment method is eligible. This is more of an issue in Europe than the US, but certain methods, like PayNearMe, may occasionally be excluded from bonus offers.

3. Play Through Your Bonus Like a Pro

Unless it’s a wager-free bonus, you’ll need to hit a casino playthrough target before you can request a withdrawal. These targets are always multiples of your bonus. For example, if you claim a $10 bonus with a 5x playthrough, you need to wager 5 x $10 ($50).

The most efficient way to hit playthrough targets is by playing popular online slots. Not only are betting rounds over sooner in slots than in other casino games, but 100% of your wager counts. That’s not the case for most casino table games.

The average contribution weighting - i.e., the percentage of a bet that goes towards your playthrough target – for table games is 10%. So, if you wager $1 on blackjack, only 10 cents goes towards your target.

The same $1 wager on a slot game clears $1 of your target, which is why pros play slots when they’re chasing bonuses.

4. Watch the Clock

All offers expire, even the very best casino bonus online. In most cases, you’ll have between seven and 14 days to hit your playthrough target.

Some top online casino bonuses have a 30-day playing period. Whatever the time limit, make sure you’ve hit your playthrough target before the bonus credits expire.

5. Don’t Game the System

This tip is one that very few people talk about, simply because they don’t know about it. I’ve been around the block more than once, which is why I never try to game the system.

By that, I mean you shouldn’t play in a way that’s either illegal or that contravenes a casino’s bonus terms. Illegal activities are things such as fraud (i.e., having multiple accounts), exploiting a casino’s software, and playing with money that isn’t yours.

Contravening a casino’s bonus terms is when your bets breach the rules. For example, betting on restricted games doesn’t contribute to your playthrough target. Another overlooked mistake is system betting.

Otherwise known as low-risk betting, these strategies are frowned on by online casinos. If you’re deemed to be using a low-risk strategy, such as covering over 90% of the board in roulette, your bonus will be revoked.

How to Claim an Online Casino Welcome Bonus

I’ll admit that there’s a lot to take in when it comes to online casino bonuses. You need to know what’s out there, how each offer works, and the rules for converting bonuses to cash.

The good news is that claiming the top online casino bonuses is easy. As long as you’re a new and eligible player (21+ in a state with legal online casinos), it takes just four steps to claim an online casino welcome bonus:

1. Use our safe sign-up links to start the registration process.

2. Enter your details and enable the casino’s geolocation tracker to register. *Enter a bonus code, if required. If you use our links the code will be added automatically.

3. Verify your account via the link sent to your inbox.

4. Open the cashier page and make a qualifying deposit.

Complete those steps, and you’ll receive your casino bonus as a new customer.

How to Use an Online Casino Sign-Up Bonus Responsibly

I’ve given you my top five tips for claiming welcome bonuses. Most of those tips can also be applied to ongoing offers, such as reload bonuses. What I haven’t discussed is the importance of playing responsibly.

I’ll end this guide with some general guidance on how to gamble responsibly. Right now, I want to tell you how to view bonuses. You should treat every offer, even the very best online casino bonus, as an added extra.

Don’t try to claim all bonuses at any cost. It’s tempting at times, particularly when the best online casino promotions are worth upwards of $1,000. However, you’re risking a lot more than you stand to gain if you’re playing recklessly.

By that, I mean you’ve claimed a bonus without reading the terms, and now you’re fighting to hit an unreasonable playthrough target. It can also mean that you’ve deposited more than you can afford just to get a bigger bonus.

The problem is the same in both instances: you’ve got to play more often and for higher stakes than you should. Even experienced players struggle to play responsibly when they’re chasing bonuses, but you can do it by keeping these tips in mind:

• Bonuses are added extras; they’re not integral to your bankroll.

• Always read the terms so you understand the task at hand.

• Withdraw from offers or let them expire if you can’t comfortably hit the playthrough.

Follow these three rules, and you won’t make the same mistakes other players do.
