Best Casino Bonuses in America | 2025

Casino bonuses are the closest you can get to beating the house. You get to play your games with their money and if you win you get to keep it! It's a great way to try out a casino at a discount. 

Keep this mental attitude and you'll not just make the most money from your bonus, you'll also get the most fun for your money -- or even better, the house's money! 

On this page, I'll show you top casino bonus offers at the best online casinos in the United States. 

• These bonuses depend on what's available in your state. Change the state using the drop-down menu.
• If real money online casinos aren't available in your state, you’ll see your next best option, whether that be choosing from a list of sweepstakes casinos (where you can still win real money) or a social casino where you cannot. 

If you see real money casino bonuses on the list, great, I'll show you how to work out what they are worth here. Sweepstakes bonuses I'll deal with down the page.

There are a lot of big numbers floating about in this list, but are the numbers real? I'll get to the various types of bonus later, but for now, I'll focus on helping you work out what the numbers you see on the list mean in real money.

You'll see a lot of these bonuses with a deposit match. If you deposit a $1,000 then the casino will usually add $1,000 to your account. This is an awesome deal but notice the wagering requirements. 

A low wagering requirement would be 15x. This means you have to wager $15,000 before you can cash out any of the bonus amount or any winnings from it. 

Scroll back up the list and you'll see the wagering requirements for each offer. 

Sweepstakes bonuses are a little bit different. Smaller, but relative to the stakes and cost of play they offer real value. You don't get dollar figures at sweepstakes, you get coins. Two types of coins, usually gold coins and sweeps coins, but different casinos use slight variations of the terminology.

Gold coins turn into sweeps coins and sweeps coins turn into cash. That's the bit to remember.

Social casinos using the sweepstakes system don't standardize on any specific conversion rate from gold coins to sweeps coins. You have to look at the terms and conditions. There is a de facto standard for sweeps coins; one sweeps coin almost always has a value of $1.

If you get the details of one of the bonuses listed above, you can see how it works using our Wagering Calculator. Try a few out and see how each bonus is different. 

Every casino wants to be different but there are only so many ways to package a promotion. These are the typical bonuses I see most regularly.

An online casino welcome bonus is applied to your very first deposit at most gambling sites. A common version is a bonus that doubles your first deposit amount, with or without additional spins in selected games. 

Why Claim a Welcome Bonus?

• ✅ Extra funds for online gambling
• ✅ Extended gambling sessions
• ✅ More value for what you spend

US online casino bonus codes attract new players. Everyone likes to be special, everyone wants to get a bigger bonus. Truth is, bonus codes rarely make much difference; your bonus is going to be what everyone else is offered. Unless....

Some large gambling marketing companies can arrange bespoke deals with casinos that are better than the offers you'll find elsewhere. We are one of those companies, so every now and then we'll have an offer that our competitors can only dream of! You only get this offer if you use our promo or bonus code.

The other reason for using our casino promo code is so that the casino knows that you found the offer at Casinos.com. That helps us, which is why we can help you with all the advice and content on our site. So, in advance, thank you for using our promo codes when you register for your casino bonus! 

Why Claim a Casino Bonus Code?

• ✅ Extra value that you can unlock
• ✅ Access to time-sensitive bonuses
• ✅ It helps us to help you

Online casinos with no deposit bonuses are ideal if you want to try out a new site without having to spend a cent. These bonuses are typically smaller than any casino deposit bonus and come with attached T&Cs like all other offers. 

A no deposit bonus is a simple way to experience the casino and gamble without any of the stress! It doesn't get much better than that. The main downside, however, is that no deposit bonus casino sites are becoming rarer these days. 

Why Claim a No Deposit Bonus?

• ✅ Real money wagers using their money, not yours
• ✅ No financial commitment 
• ✅ Great way to try before you buy

With free spins, the concept is pretty simple. The casino rewards you with spins that you can use to play designated slot games. You don’t have to spend any extra money for those spins — they’ll be credited to your account!

Of course, free spins are available as standalone promotions. However, they’re a lot more common as an additional reward when you claim other casino bonuses.

Why Claim Free Spins?

• ✅ Free plays on online slots
• ✅ Low wagering requirements to cash out winnings
• ✅ A chance to win a much bigger bonus

Now these I like! Cashback bonuses represent a percentage of the money you lose, given back to you by the casino. Have a bad day and cashback bonuses make everything seem a lot brighter. 

Why Claim a Cashback Bonus?

• ✅ Real money losses aren't as harsh 
• ✅ Protection of your bankroll over time
• ✅ Winning something even when you lose

First you need to register with the casino offering the bonus. I can do this in a couple of minutes, but then I have many, many accounts at different casinos!

• Hit a “Play Now” link on this page to land on the casino’s official site – this avoids you ending up at sketchy scam sites. 
• Select your state if prompted, then fill out the registration form with your personal info to comply with age and identity verification rules.
• Enter any Bonus or Promo code listed in the offer above – it’s good for us and guarantees you the advertised deal.
• Check the boxes to confirm you’re of legal age and agree to the terms and conditions. You’re nearly done!
• My personal advice: head straight to the responsible gaming section (usually at the page bottom) to set time or spending limits for safe play. Don't forget to sign up with the casino rewards program. 
• Review the T&Cs – Pay attention to the bonus terms and conditions. These are linked to the bonus description. Check out the wagering requirements, minimum deposit, eligible games and payment methods and the expiration date.

Whatever else you do, have fun. Don't make it about the money, make it about the entertainment. That's how I extract the most value from my bonuses.

I don't play online casino games to get rich. They're fun, they are a few hours of entertainment for which I pay a few dollars that I can afford. Every now and then I get a win big enough to make me feel good. I still can't beat the house, nobody can in the long run.

Casino bonuses are the closest you can get to beating the house. A great way to try a new casino at a discount.

Keep this mental attitude and you'll not just receive a bonus, you'll get the most entertainment for your money which in this case means their money!

Some Online Casino Bonus Dos and Don'ts

• Don't play higher stakes than you normally do just to try to earn a bigger bonus. It generally ends badly.
• Don't redeposit if you've reached your budget limit. It's not worth it.
• Do read the Terms and Conditions before you claim the bonus.
• Do, unless you're a high roller and know what you're doing, avoid the bonuses that have very high wagering requirements. If you are a high roller, fill your boots!
• Don't forget this is fun. I repeat myself, but the aim is to enjoy your time, not get the last red cent of extra value.

Focus on the real aim of playing at online casinos. It's entertainment with the chance of a prize. In fact prizes can come thick and fast but statistically, you will lose money in the long run. I hate that phrase lose money. I don't lose money when I play, I pay money to play.

Casino bonuses make it cheaper to play. They are a discount on the price. Casinos need to attract customers, and they need to keep them playing. They spend a lot of money on this so there's no reason not to take your fair share. All you have to do to get your hands on that cash is hit the Play Now button on any of the offers I listed above.
