It means that, if you know what you’re doing and get a bit of luck along the way, you can wind up winning real money online totally free.

This page is your complete guide to the best no deposit casinos and how they work.

We’ve got all the details you need to know about no deposit bonuses: the different types, how you can claim them, no deposit casino bonus codes, advantages and disadvantages, and much more.

Everyone loves getting something for nothing, and we’re going to show you how you can do just that at online casinos.

Best No Deposit Casino in the US in September, 2023

Casinos and sportsbooks offer bonuses and promotions for one very important reason: to attract new players and encourage people to try out the site. The hope is that once you get through the virtual doors with your bonus, you’ll become a loyal member and maybe deposit some of your own money down the line.

No deposit bonuses are arguably the most attractive offer they use, for the simple reason that they are totally free. They mean you can sign up and start playing real money games without ever reaching for your wallet.

All online casinos in the US have welcome bonuses for new players, but not all of them include a no deposit bonus as part of the offer. Their rarity is another thing that makes no deposit bonuses so sought after and valuable.

Here you can find the best US casinos which have no deposit bonuses up for grabs right now.

It’s worth noting that if your favorite US casino isn’t included below, there’s still a decent possibility that they’ll come up with a no deposit bonus down the line.

• BetMGM – $25 free bonus cash
• Borgata – $20 free bonus cash
• Unibet – $10 free bonus cash
• Harrah’s – $10 free bonus cash

Best No Deposit Casino Bonuses

Unlike the vast majority of casino bonuses, no deposit bonuses are entirely free. Normally, all you need to do to claim one is register with a casino, and you’ll get the chance to play some real money games for free.

That’s the general idea, but no deposit bonuses do come in different shapes and sizes. We’re going to cover them all in this section.

The most common type of no deposit bonus involves receiving a small amount of bonus cash when you register with a site – normally around $10 or $20. Bonus cash works just like regular cash, in that you can use it to play real money games, with the difference being that you can’t withdraw it right away.

BetMGM No Deposit Bonus

One of the best no deposit offers available right now is from BetMGM.

As soon as you create your account, you’ll be given $25 FREEPLAY® – which is what BetMGM calls bonus cash.

This is an excellent offer for a couple of reasons. For one, the wagering requirements attached are just 1x, so once you gamble all your bonus cash once you’ll be able to withdraw your winnings. This is basically a dream scenario for no deposit bonuses.

Better still, there’s still a deposit bonus – worth up to $1,000 – waiting for you if you do decide to make a deposit down the line. This offer really is the best of both worlds.

Borgata No Deposit Bonus

Borgata’s welcome offer is very similar, which is no surprise as both sites are owned by the same parent company  – MGM Resorts International – and share similar software.

In this case, you’ll receive $20 instead of $25 – but the rest of the conditions are the same.

The only slight downside to these two offers is that the timeframe to turnover the bonus cash is a little tight. You have 7 days for the no deposit bonus (which is fine) but 14 for the deposit bonus – which isn’t that long if you have up to $1,000 to play through.

If you prefer a little longer timeframe, Unibet is a good option.

Unibet No Deposit Bonus

With this offer, you’ll get less money – $10 up front and a deposit bonus worth up to $500 later – but you’ll have a full 30 days to complete the wagering requirements. Plus, the $10 also has just 1x playthrough.

Harrah’s No Deposit Casino Bonus

Harrah’s also gives you $10 on sign up, and also with 1x playthrough.

All of these offers are pretty similar, and classic examples of no deposit bonuses.

The other main no deposit offer you’re likely to come across involves free spins or free bets. When a casino gives you free spins, it means you can play real money games for free – with each spin representing an individual turn on a slot machine. Each free spin has a monetary value, often $0.10 or more.

While free spins are often included as part of a deposit bonus, or as an on-running promo for regular players, they can also be handed out as a no deposit bonus when you sign up. For example, a casino might give you 20 free spins when you register, with no need to use any of your own money first.

Just like with bonus cash, the money you win from free spins often has terms and conditions attached before it can be withdrawn, and we’re going to cover them in the next section.

Below, you can check out a handy guide to the different no deposit bonuses available at US casinos right now.

No Deposit Bonus Terms and Conditions

We’ve already mentioned some of the terms and conditions associated with the bonuses above, and in this section we’re going to explain them a little more in depth. Every bonus at the casino has some small print you need to be aware of, and no deposit bonuses are no different.

The single most important factor is something called wagering requirements or turnover, and it refers to the number of times you need to gamble with some bonus cash before you can withdraw it or your winnings.

Wagering requirements are designed to stop people simply signing up to a casino, claiming their no deposit bonus and immediately withdrawing it, without ever playing any games.

For example, let’s say you get a no deposit bonus of $20, with 20x wagering requirements attached.

You’ll need to place bets totalling $400 ($20 x 20) before you can withdraw any of your winnings. It seems like a lot, but remember you don’t need to win $400, just bet that amount over time. Whatever your balance is once you’ve bet that much is yours to keep.

Getting a bonus with just 1x turnover – which you can right now at the casinos we’ve mentioned – is excellent.

There is also an expiry date on bonus cash, meaning you’ll need to complete the wagering requirements within the stated time frame. Often, this will be a week or two, but can be longer.

The next thing we need to understand is the concept of weighted contributions. This refers to the idea that different games count towards clearing wagering requirements at different rates.

When we talk about wagering requirements of 20x, this is the basic rate and normally refers to slot games. Slots are consistently the most popular type of game at online casinos, and the majority of casino promotions are focused on them.

If you want to play table games like blackjack or roulette, they tend to count towards clearing your bonus cash at a lower rate – often at something like ¼ of the basic playthrough rate.

With 20x playthrough, this effectively means 80x if you decide to play table games. Bonus cash is also often not eligible for use on live dealer games.

All of these terms and conditions will be explained in the small print of the bonus offer, and it’s absolutely essential that you read it carefully before you claim any bonus.

Like we said, no deposit bonuses are great because they give you a genuine chance to win real money for free – but you need to know what you’re doing to give yourself the best chance.

Best Bonuses By Software

There are loads of ways to play at online casinos. Playing on a desktop or laptop computer has slowly given way in popularity to mobile gaming, and all the top US casinos now have dedicated apps for both iOS and Android devices.

Playing via a mobile app means you have 24/7 access to your favorite casino or sportsbook, anywhere you are connected to the internet.

Sometimes casinos release mobile-exclusive bonuses, to encourage players to try new types of software.

However, all the bonuses covered on this page are available for both the mobile and desktop platforms of the respective casinos. No matter how you play, you’ll get the same no deposit bonus.

Of all the casinos on the list, BetMGM is the highest rated on the App Store, at 4.7/5. If you like to play on your iPhone, this is a great option.

On the Google Play Store, Borgata tops the list with 4.4/5.

How to Claim a No Deposit Bonus

No deposit bonuses are normally easy to claim, as long as you follow the casino’s instructions. Gambling sites aren’t really looking to trick people with welcome bonus offers; they are designed for you to take advantage of.

There are a couple of actions you may need to take to claim your bonus.

One is using a promo code or bonus code. This is like a password which triggers a specific bonus, and you can normally either type it in during the registration process, or afterwards in the cashier or in your account.

This is the case with Unibet’s no deposit bonus – you’ll need to use the code UBCASINO10 when you create your account.

Sometimes casinos publicize promo codes themselves, but sometimes they are released exclusively by partners of the casinos as a special offer.

If no bonus code is required, you still may need to opt-in to claim your no deposit bonus. This could be done by clicking a confirmation button or checking a box during the signup process, or in your account afterwards.

Or sometimes there is no action required on your behalf at all, and the casino will simply credit your account with the bonus once you sign up.

Again, the important thing is to read the bonus instructions carefully, and you should have no trouble.

The big attraction with no deposit bonuses is that you don’t need to spend any money to claim them, but chances are you’re going to be making a deposit at some stage down the line. Plus, if you wind up winning from your no deposit bonus, you’ll need a way to withdraw your cash.

US casinos support lots of different payment methods. Below are some of the most common options:

• Bank Cards (Visa / MasterCard / Amex / Discover)
• ACH Transfer / e-Check
• Bank Transfer
• E-wallets (PayPal / Skrill)
• Play+  Card
• PayNearMe (deposit only)
• Cash at Casino Cage
• Paper Check via Mail (normally for withdrawals)
• Wire Transfers
• Cryptocurrency (Bitcoin / Ethereum)

Why Should I Look for No Deposit Bonuses?

There’s a good reason no deposit bonuses are so highly prized. In fact, there are several.

Here are the main advantages of this type of bonus, according to our experts:

• No deposit bonuses are more or less the only promotion casinos offer which is genuinely free. It’s a chance to win real money with no financial commitment on your behalf, a shot to nothing. You don’t need to ever type in your bank details, and if you lose your no deposit bonus you can walk away with no questions asked.
• No deposit bonuses are a great way to test out a casino, or a couple of casinos, with no pressure. You can choose to play more or deposit some money down the line if you want, but there’s no obligation. They’re a great way for beginners to get their feet wet with a new site, or experiment with unfamiliar games.
• They are a god-send for micro stakes players. $20 might not seem like a lot to high rollers, but for anyone who likes to play at smaller stakes it represents a pretty healthy bankroll.

Downsides to No Deposit Bonuses

We also asked our experts if there were any drawbacks to no deposit bonuses, or why someone might want to choose a different type of promo. Here’s what they came up with.

• For higher rollers, no deposit bonuses just might not be attractive. If you’re used to betting $10 a hand or a spin, you probably won’t be enthused by a $10 bonus and the associated wagering requirements.
• On a similar note, there are often alternative welcome bonuses which allow you to claim considerably more bonus cash, even if it does mean you’ll also need to deposit some of your own cash. If you’re comfortable spending a decent chunk of your own money up front, you can wind up with a much bigger bankroll from a regular deposit bonus, compared with a no deposit bonus.
